What are the scientific maintenance methods of sprayers?

Because of its ease of use and high work efficiency, the electric super-large capacity sprayer is loved by more and more vegetable farmers, and has now become the main tool for the prevention and control of pests and diseases in the greenhouse. However, electric sprayers are relatively "delicate", and once they are not properly operated and maintained in time, they are prone to failure. How to maintain in order to extend the service life of the sprayer, the reporter interviewed Manager Han, who is engaged in the sales of the sprayer, and he suggested that vegetable farmers should do the following.

First of all, when you use it for the first time, check whether there is air leakage in each connection. When using, install clean water test spray first, and then charge the agent. When adding medicine, it is necessary to add the agent first and then add water, and the liquid level of the liquid medicine should not exceed the safety water level.

Before spraying, open the electric sprayer in advance to make the air pressure in the barrel rise to the working pressure to ensure smooth spraying.

Secondly, after the sprayer is used, it is necessary to first clean the liquid medicine barrel, hose, spray rod and other parts, and pay special attention to removing the oil scale on the pump and the soil on the bottom recess of the liquid medicine barrel. Because most pesticides have a certain corrosive effect on the sprayer, after disuse, it should be washed with alkaline water in time, and then rinsed with water. Especially after spraying corrosive pesticides such as Bordeaux liquid, it is best to soak them in alkaline water for 1 2 hours.

Care should be taken to prevent rust. All parts that can be disassembled must be removed and cleaned. The inner pipe wall of the spray rod and nozzle should be coated with engine oil to avoid moisture and rust.

1. After the sprayer is out of use, the appearance of the liquid medicine barrel, hose, spray rod and other parts should be scrubbed clean, and special attention should be paid to removing the oil and dirt on the bottom of the liquid medicine barrel.

Second, because most pesticides have a certain corrosive effect on the sprayer, so after disuse, it is necessary to wash it with alkaline water in time, and then rinse it with water, especially after spraying Bordeaux liquid, it is best to soak it in alkaline water for 1-2h, because Bordeaux liquid is very corrosive.

Third, pay attention to prevent rust. All parts that can be disassembled must be removed and cleaned. The inner pipe wall of the spray rod and spray head should be washed with oil to avoid moisture and rust.

Fourth, we must do a good job of maintenance. Inspect each part in detail, all the parts that are fixed by the screws or the places that are often worn should be coated with glycerin, and if there are damaged parts, they should be repaired in time for reuse.

5. After completing the above inspection, the small parts should be wrapped in paper and placed in the liquid storage cylinder to avoid accidental loss. The whole sprayer should be hung in a dry and ventilated warehouse, not in a dark and damp corner, and not in the open air.

Winter is the peak period for the occurrence and control of various vegetable pests and diseases, and it is also the time when the frequency of use of pesticide application equipment such as sprayers is high.

The sprayer is an important plant protection device widely used by many rural farmers.

Although it is in the winter greenhouse vegetable pest control materials and equipment preparation stage, but some farmers usually only pay attention to the use of equipment, do not pay attention to maintenance, when it comes to use, often envy the rest of the hands and busy, resulting in a lot of inconvenience in the actual operation.

So how to use the nebulizer maintenance? What is the solution to the negrometer failure? Let's find out.

Use and maintenance of sprayers.

1. When using, check whether there is air leakage at each connection of the sprayer, and then fill it with water for spraying.

2. After adding the liquid medicine, the liquid level should not exceed the water line.

Before spraying, the plate shaker is more than 10 times to make the air pressure in the barrel rise to the working pressure.

Note that the board rocker should not be overforced, so as not to burst the air chamber.

3. After the spraying operation is completed, the residual liquid in the bucket should be poured out in time, and then washed with water and dried upside down; At the same time, check whether there is stagnant water in the air chamber, and if there is stagnant water, remove the water outlet joint to release the stagnant water.

Note that the sprayer that has been sprayed with herbicide should be distinguished from other sprayers, and it should not be used to spray insecticides.

4. When it is no longer used in the short term, the main components should be cleaned, dried and installed, and placed in a cool and dry place; If you don't use it for a long time, pay attention to coating each metal part with butter to prevent rust.

How to deal with the sprayer troubleshooting.

1. The switch is leaking.

Wear of the switch gasket or wear of the switch asbestos wire will cause the switch to leak, and the new gasket or asbestos wire should be replaced.

2. The switch is not flexible.

The sprayer has not been used for a long time, the switch will be embroidered due to the liquid medicine, you can remove the switch and put it in kerosene to clean, wipe off the rust, apply an appropriate amount of lubricating oil and install it, and tighten the switch cap.

3. The air chamber cannot be inhaled, and the rocker cannot be pressed downward.

It may be caused by dry shrinkage, hardening or cracking of the leather bowl or loose nut at the bottom of the leather bowl.

The leather bowl should be slightly pressed open or replaced with a new leather bowl, soaked in animal oil, lubricated and expanded, installed, coated with a little engine oil, and tightened the bottom nut.

There is a possibility that the nozzle hole of the nozzle is blocked, the filter screen in the casing is blocked, or the inlet and outlet balloon valves are held by dirt.

Spray holes and debris should be dredged; If the casing is blocked, the casing should be disassembled, the filter should be cleaned, and the ball valve and dirt should be checked.

5. The plug rod of the air chamber rises automatically, and water bubbles up at the top of the gland.

It is mostly caused by cracks in the air wall or the bottom of the air chamber that are desoldered or the glass ball in the valve shell is blocked by debris, which cannot be sealed with the valve body or the leather bowl is damaged.

When repairing, the Wei brothers should use soldering to repair cracks, valve body sundries, and replace leather bowls.

6. Air leakage from the air chamber gland or air leakage from the water cap.

The reason is that the skin gasket is damaged or the protrusion is desoldered from the air chamber, and the gasket or tin soldering desoldering place should be replaced.

First of all, it is necessary to quit bad habits and relax the mood, and in addition, it can be more than 20 minutes longer, it is recommended to eat more mutton, leeks, oysters, onions and other warm foods, appropriate exercise, and improve physical fitness. I hope my answer is helpful to you.

There are three main points in the maintenance of the sprayer.

Operate according to the instructions of the machine, check and adjust the technical status of each component, and lubricate each lubrication point. Keep it clean and remove the mud in time.

Clean water rinsing: Spray with clean water for a few minutes after the spraying operation every day to remove the residual liquid medicine in the liquid tank, liquid pump and pipeline, and finally remove the clean water.

After the storage of the sprayer is completed, if it is parked for a long time, in addition to cleaning the liquid tank, liquid pump and pipeline, etc., the V-belt, spray hose, nozzle, mixer and suction pipe and other parts should be removed, and these parts should be cleaned and placed in a cool and dry place with the body. The sprayer should not be stacked with corrosive items such as fertilizers and pesticides to avoid rust damage. Rubber products should be hung on the wall to avoid pressure and fold damage.

If not properly operated or stored, the sprayer is susceptible to corrosion, thereby shortening the service life, so the following points should be paid attention to in terms of maintenance:

2. After the operation, rinse and spray several times with clean water in time to clear and clean the remaining liquid medicine in the liquid medicine tank, liquid pump and pipeline. Check the sprayer for malfunction and allow it to dry. 3. After the end of seasonal operation, the sprayer is stored for a long time, in addition to cleaning the body, it should also remove the V-belt, spray hose, nozzle, mixer and suction pipe and other parts, rinse them, and place them in a cool and dry place with the body.

If it is a rubber product, it needs to be hung on the wall to avoid crushing damage. At the same time, it is necessary to stay away from corrosive items such as fertilizers and pesticides to avoid rust damage.
