Siphon liquid blasting machine blasting,hand sprayer  the use of high-speed compression blasting produces a negative pressure flow ejector effect, the abrasive fluid tank through the hose suction and discharge of abrasive blasting gun, and then with the high-speed flow of compressed air from the nozzle blasting onto the workpiece surface, to sandblasting.
Liquid and conventional dry sand blasting machine are different, liquid abrasive blasting machine placed in the water, with the mill compressed air through the pump and the high-speed jet lance the grinding fluid workpiece surface to be machined, to the part surface cleaning and light decoration effect. Liquid sandblast machine high efficiency, garden hand sprayers abrasive consumption, to achieve improved surface finish and surface intensity. As a result of wet sandblasting machine liquid sealing operation, liquid abrasive grinding using water and natural sand (pill), but also a cycle work, so the work does not produce dust, does not emit toxic waste, no pollution to the environment produced equipment installation convenient and simple, does not require a separate workshop.
Box-type liquid blasting machine, blasting on mechanical parts, you can make the mechanical parts of the surface on the basis of the original increase of 0.5 to 2.0 finish, if we adopt a different pill material also allows mechanical parts to achieve light or matt effect. Liquid blasting is surface polishing, polishing one of the best ways.

Matters described using silicon carbide

Because use of silicon carbide, high temperature, high temperature, anti-oxidation, corrosion resistance, heat up fast, long life, high temperature deformation, easy installation and maintenance features. Good chemical stability. If the power supply system with automated matching can get an accurate constant temperature, but also according to the actual needs of the production process according to curve the thermostat. Now widely used in national defense, machinery, metallurgy, lightweight, ceramics, semiconductors, laboratory analysis, scientific research and other areas, for a variety of electric kiln furnace electric heating element. To test each silicon carbide heating element is good work, power clamp meter tests available individually measured current. In the same area a voltage equal to the current requirements under similar deviation does not exceed 10%, if the individual current is too small to explain the resistance. If the current is too small, not too much resistance is poor contact pin press. If there is no current may be silicon carbide heating element has been broken, should further examine the replacement. Crack easily when wet silicon carbide, GD rod contacts easily broken after damp damage, therefore, silicon carbide in the store, the installation process should pay attention to moisture, so as not to affect their life. In order to ensure uniformity of furnace temperature and rods bear the load before installation to be with the group, each silicon carbide resistance deviation does not exceed 10%. Silicon carbide hard and brittle,agricultural sprayer in the handling, unpacking and installation, maintenance when things do not care to avoid damage. Power to run an electric furnace at the beginning, to gradually slow step, can not be a plus full load, otherwise they will be the impact of current is too large, resulting in damage to silicon carbide.

By adjusting the addition of silicon carbide components electrical load, reducing the surface load density. If a smaller load and low surface load density, kiln temperature is high, you can maintain a fairly long life, either by changing the silicon carbide component installation count, or change the component specifications to regulate heat size of the surface to achieve. Surface load density and inversely proportional to temperature furnace, the furnace temperature is higher, the smaller the permissible surface load density; overload will cause decomposition of silicon carbide heating element overheated surfaces off, burning. To ensure the component life,portable sprayers should allow the heating element in the overload condition, the general control its value 6 ~ 8W/cm2. Non-silicon carbide overload. If for some reason stick breaks or discover uneven bars fever, localized phenomenon was incandescent or dark a period of time, indicating that aging is inconsistent rods, a section of resistance that much difference, should be shutdown for maintenance rods, replace all the best bars . Such as replacement of some of the new rod or rods when the new single from the new and used rod rod resistor resistor matching inappropriate, leading to unbalanced load, temperature uniformity. Therefore, due to large differences in resistance level rod temperature difference is large, will seriously affect the life.

How to extend the life of electric sprayer

Sprayer because easy to use, high efficiency, loved by more and more farmers, has now become a major greenhouse pest tool. However, electric sprayer more "delicate", once in use, improper operation, maintenance is not timely, it is prone to failure. How to maintain,garden water sprayer it can prolong the life of sprayer is recommended farmers should do the following.
First of all, the first official use, check all connections for leaks. When used, install water spray test, then loaded agents. Dosing when the first Canadian Pharmacy, add water, the liquid's surface can not exceed the safe water line. Before spraying, electric sprayer opens in advance, so that the barrel pressure up to a pressure of work, to ensure a smooth spraying.
Secondly, the sprayer after use, to first put the barrel body electric sprayer, hose, spray bar and other parts clean, paying particular attention to clear the pump and liquid grease on the bottom of the barrel recess soil. Because the majority of pesticides on sprayers have some corrosion, therefore disabled, to promptly wash it again with lye, then rinse with water. Especially such as Bordeaux mixture sprayed pesticides after corrosive, preferably with lye soaked 1-2 hours. Pay attention to prevent rust. Those who can disassemble the parts, must be removed to wash clean. Lance, nozzle inner wall to use the oil painting, avoid damp rust.
If you do not use the spray near term, the main components should be clean, dry bottles in a cool dry place. If the long-term need,liquid sprayer  all metal parts have to be buttered, to prevent rust.
In addition, the core component of electric sprayer electric sprayer diaphragm pump and battery. Although there are several pumps available in the market, but these pumps are afraid of clogging. So be sure to use a clean flush drugs, be sure to use a small water filter to filter to prevent clogging.
Also, remind farmers: sprayer after disabling its fully charged battery should be placed in dry shade, dry place, every one or two months on one charge. If you save electricity after a shorter time, then add distilled water inside a timely manner.

The use of degradable plastics

The use of degradable plastics has two main areas: First, the original use ordinary plastic field. In these areas,agricultural sprayer  the use of post-consumer plastics or difficult to collect back damage to the environment, such as agricultural film and disposable plastic packaging, plastic instead of other materials is based on two areas. Use of biodegradable plastics in these areas can bring convenience, such as golf courses with the ball screw, rainforest reforestation seedlings with fixing material. Specific application areas are as follows:
1 Agriculture and Forestry, mulch, water retention materials, nursery pot, seedbed, rope, pesticides and agricultural fertilizer release material.

(2) should be promptly after use rechargeable batteries, such as not using the best supplement it once every three months.
3 Check that the AC charger input voltage match.
4 operator's attention to "safety mark" (garden sprayers)a reminder not to breach their operations.

Electric sprayer charging routine maintenance and common sense

Buy a new fruit tree sprayers  simply charge with the barrel once opened, the inside of the shedding of wire can be inserted for charging.
Electric sprayer diaphragm pump working for some time suddenly no water, and most are not clean because there are particles of impurities, resulting in blockage of the pump, and you just need to pump apart, clean the inside of the impurities, the pump can be working.
If you use the process in a water leakage, check whether it is loose screws, tighten all the screws first good (except that the head does not move), or if necessary replace the leaking pump head.
Electric sprayer normal maintenance is also very important, in general, electric sprayer immediately after use later to charge, there are some people in the use of the latter, forget the timely charge, think of it the next day when the rechargeable battery has been scrapped half Therefore, in normal use and maintenance is very important, he determines the service life of electric sprayer.
Electric bottle plastic sprayer in the slack period is imperative to maintain, under normal circumstances, one to two months, charge and discharge time, you must first electric sprayer, putting it to work until the water run out of power until then charge, so you can make more long battery life.
Best electric sprayer after use with clean water to remain liquid in the pump to be cleaned inside out, the drug also need to be cleaned barrel, especially to the slack season, it is best to use the oil pump motor ripped out the clean up, and put some butter to prevent rust next year the motor is not working.
Note: For battery maintenance either under what circumstances it is better to have run out of battery power in the later charge, so the battery is the best safeguard, such a situation the longest battery life.

Sprayer dispensing needs attention

Now a lot of friends of farmers spraying herbicides are not alone in the preparation of dilutions, but directly to the herbicide added electric sprayer, electric sprayer tank in preparation dilutions, with a good directly after spraying. However, due to the technical preparation of the herbicide master well diluent, in the preparation process tends to occur, which directly affect the herbicidal effect. In order to improve the control effect of herbicides in the dispensing process must pay attention to the following four questions:
1 herbicide formulations
There are many formulations of herbicides with different formulations prepared in different ways. Such as emulsions, liquid and gel suspension agent will quickly dissolve after water and spread of these formulations can be further dilution method herbicide formulated about a certain amount of herbicide directly into the nebulizer dilute garden sprayers immediately after good Shi. 72% Doyle emulsion, 90% Wo Nice EC can use this method. Wettable powders, dry suspension emulsion and other formulations step dilution method can not be used, but must be prepared using the two-step dilution method: The first step is accurately weighed on demand herbicides, add a little water stir, it is fully dissolved liquor. The second step is to add a certain amount of mother liquor certain amount of water, diluted to spray evenly. 75% superstar hanging drying emulsion, 25% WP nitrofen and so must be diluted using this method, and must not be a one-step dilution dilution.
(2) preparation of diluent
In the medicine cabinet in the preparation of electric bottle sprayer diluent, you must first kits add about 10 cm deep water only after the mother liquor was added slowly to the pharmacy or medicine cabinet, and then add water to the water line can be sprayed. Never add water in the water tank before or will not fill with water and pour it into the tank agents or liquor, because it is difficult to prepare a homogeneous diluent, will seriously affect the control effect.
3 with a good liquid medicine chest immediately after spraying
The reason is the proportion of various herbicides and not exactly the same proportion of water, such as herbicides gravity than water, stored herbicide will sink over time, resulting in lower liquid concentration, the upper liquid concentration is small, serious impact on weeding results.
4 electric sprayer in the dilution was added to the water line of electric sprayer as well
Electric sprayer in the spray dilution was added to the water line as well, must not be filled at once. If the medicine chest full of electric sprayer, spraying personnel in the liquid medicine chest when walking is difficult to shake, Pharmacy prone to sinking or floating phenomenon, affecting the uniformity of the liquid, thus affecting the herbicidal effect. In addition, the application personnel also easy when spraying liquid spilled out from the medicine chest catchy, drip application personnel to the body, so the medicine cabinet in the liquid must not overfill.

How to maintain electric sprayer

Electric chemical sprayer due to ease of use, high efficiency, loved by more and more farmers, greenhouse pest control has become the main tool. However, electric sprayer more "delicate", once in use, improper operation, maintenance is not timely, it is prone to failure. How to maintain, it can prolong the life of spray, the reporter interviewed the work in the sprayer sales Hanjing, he suggested that farmers should do the following.
First of all, the first official use, check all connections for leaks. When used, install water spray test, then loaded agents. Dosing when the first Canadian Pharmacy, add water, the liquid's surface can not exceed the safe water line. Before spraying, electric sprayer opens in advance, so that the barrel pressure up to a pressure of work, to ensure a smooth spraying.
Secondly, the sprayer after use, should be the first to liquid barrels, hose, lance and other components clean, paying particular attention to clear the pump and liquid grease on the bottom of the barrel recess soil. Because the majority of pesticides on sprayers have some corrosion, therefore disabled, to promptly wash it again with lye, then rinse with water. Especially such as Bordeaux mixture sprayed pesticides after corrosive, preferably with lye soaked 1-2 hours. Pay attention to prevent rust. Those who can disassemble the parts, must be removed to wash clean. Lance, nozzle inner wall to use the oil painting, avoid damp rust.
If you do not use the spray near term, the main components should be clean, dry bottles in a cool dry place. If the long-term need, all metal parts have to be buttered, to prevent rust.
In addition, the core component of electric manual sprayer  umps and batteries. Although there are several pumps available in the market, but these pumps are afraid of clogging. So be sure to use a clean flush drugs, be sure to use a small water filter to filter to prevent clogging.
Remind farmers: sprayer after disabling its fully charged battery should be placed in dry shade, dry place, every one or two months on one charge. If you save electricity after a shorter time, then add distilled water inside a timely manner.

How to Grow Cassia and pest control

Cassia prefer warm, humid climate, soil strict, slightly barren in places where it can grow. Drained, deep soil, loose sandy loam optimum planting can also be used in sporadic land planted courtyard.
1, pest control: ⑴ main ring rot disease is, in the incidence of spraying Bordeaux mixture 1:1:200, serious lime sulfur spray 0.3 Baume for prevention and treatment. ⑵ aphids more serious harm in the seedling stage, 40% of available times or dimethoate 2000 1:10 tobacco, lime for prevention and treatment. ⑶ morning liming can prevent slugs.
2, Harvest: bottle sprayer year 10 months late, Cassia fruit ripening. When the pods from green to brown, use sickle cut off from the base of the plants, placed drying yard threshing season, cleanse impurities, select full, no worm for the species.
3, sowing: Cassia by seed propagation, the South in the spring or summer, the northern front in Guyu. Selected full grain seeds with 50 ℃ warm water soak 1 day and night, to make it fully swelling, remove and dry surface moisture can be planted. In drilling is appropriate to open 6 cm spacing 50-70 cm deep ditch, the seeds evenly thrown into the trench, and then the casing 3 cm, slightly compacted, electric agricultural sprayers about 10 days after sowing may emerge. Height 3-6 cm Time seedlings, the seedlings Ruomiao or too dense pull; height 10-13 cm, combined tillage weed, plant spacing of 30 cm by singling. In case of drought, proper watering.
4, fertilization: Cassia roots, rhizobia, nitrogen fixation can play without a lot of fertilization. ⑴ height 10 cm when applied per acre thin human waste 1,000 kg to promote seedling growth. ⑵ 6 mid Zaishi human waste 1000 kg.
