How to use and maintain the sprayer and the troubleshooting methods of the sprayer.

Every winter is the peak of occurrence and control of various vegetable diseases and insect pests, and it is also the time when sprayers and other pesticide application devices are frequently used.

Sprayer is an important plant protection equipment widely used by many rural farmers at present.

Although it is in the preparation stage of materials and equipment for vegetable pest control in greenhouse in winter, some farmers usually only pay attention to the use of equipment and do not pay attention to maintenance. They are often in a hurry when using it, which brings a lot of inconvenience to the actual operation and use.

So how to use and maintain the sprayer? What is the troubleshooting method of sprayer? Let's have a look.

Use and maintenance of sprayer

1. When using, check whether there is water leakage at each joint of the sprayer, then spray it with clean water and then spray it with chemicals.

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

Before spraying, move the rocker 10 times to raise the air pressure in the barrel to the working pressure.

Be careful not to use too much force when moving the rocker to avoid the air cavity bursting.

3. After spraying, the residual liquid medicine in the barrel should be poured out in time, then rinsed with clear water and hung upside down to dry; At the same time, check whether there is water in the air chamber. If there is water, remove the water outlet connector and drain the water.

Note that sprayers that have been sprayed with herbicides should be distinguished from other sprayers and can no longer be used to spray pesticides.

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

Troubleshooting method of sprayer

1, switch leakage.

Wear of switch washer or asbestos wire will cause water leakage of switch, and new washer or asbestos wire should be replaced.

2. The switch is not flexible.

If the sprayer is not used for a long time, the switch will be blurred by the liquid medicine. You can remove the switch, clean it in kerosene, wipe off the rust, coat it with proper lubricating oil, and tighten the switch cap.

3, the air chamber can't get air, and the rocker is not hard.

It may be caused by shrinking, hardening or cracking of the leather cup, or the nut at the bottom of the leather cup is loose.

The leather cup should be slightly opened or replaced with a new one, soaked in animal oil, lubricated and expanded, then installed, coated with a little engine oil and tightened with the bottom nut.

It may be that the nozzle hole is blocked, the filter screen in the shell is blocked, or the inlet and outlet ball valves are stuck by dirt.

Spray holes and sundries should be dredged; If the housing is blocked, remove the housing cleaning screen and check the ball valve and dirt.

5. The air chamber plug rod automatically rises, and the top of the gland leaks.

Most of them are caused by cracks in the air wall or the bottom of the air chamber, or the glass ball in the valve shell is blocked by sundries, which can not be sealed with the valve body or the cup is damaged.

Repair cracks, valve body sundries and replace leather cups with soldering during maintenance.

6. Air chamber gland leaks or water cover leaks.

The reason is that the leather pad is damaged or the flange is out of welding with the air chamber, so the leather pad should be replaced or the welding spot should be welded.
