Operation and use of electric sprayer
Agricultural machinery as a good helper for agricultural production and wealth
Not only must be able to purchase and maintain, but also the correct operation, use, maintenance, and maintenance of machinery is also very important.
According to Article 23 of the "Regulations on Responsibilities for Repair, Replacement and Return of Agricultural Machinery Products", the three guarantees cannot be implemented for mechanical failures caused by personal reasons. For this reason, the majority of operators pay attention to the following four points:
1. Read the manual of the machine carefully, master the structure and performance, and don't swallow the date all the time, be self-righteous, and can't act as a "know-how".
2. Operate the machinery to follow the operating rules, and pay attention to the methods of maintenance, avoid carelessness and fooling around.
3. The functions of agricultural machinery are limited, and the speed of the load-carrying vehicle is regulated. Avoid "small horse-drawn carts", and greedy small ones and lose big ones.
4. Resolutely do not operate diseased machinery. Once faults are found in the machinery, stop the operation immediately and carry out maintenance and maintenance in time.
How to use technical knapsack sprayer
Knapsack sprayer
1. To install the sprayer parts correctly. Check whether each connection is leaking. When using, install clean water and test spray first, and then install the medicine.
2. For formal use, you must add the medicine first and then the water, and the liquid level of the medicine should not exceed the safe water level. Before spraying, move the rocker more than 10 times to increase the air pressure in the barrel to the working pressure. Do not use excessive force when turning the joystick to avoid explosion of the air chamber.
3. When the chemical liquid is first filled, since the air chamber and the spray bar contain clear water, the concentration of the chemical liquid sprayed during the first 2 to 3 minutes of spraying is low, so pay attention to the supplementary spray to avoid affecting the control effect of pests and diseases.
4. After the work is completed, you should pour out the remaining liquid medicine in the bucket in time, wash it with clean water, and pour it out. At the same time, check whether there is water in the air chamber. If there is water, remove the water connector to release the water.
5. If the sprayer is not to be used for a short period of time, the main parts should be cleaned, wiped dry and installed, and stored in a cool and dry place. If it is not used for a long time, grease all metal parts to prevent rust.
Common faults and troubleshooting methods in use
Insufficient spray pressure and poor atomization: If the water inlet ball valve is set up by dirt, the water inlet valve can be removed and the dirt can be removed with a cloth; if the cup is damaged, a new cup can be replaced; if the connection part is not installed The sealing ring, or the air leakage due to the damage of the sealing ring, can be installed or replaced.
No fogging: If the oblique hole of the nozzle body is blocked by dirt, the oblique hole can be cleared; if the nozzle is blocked, the nozzle can be removed and cleaned, but hard objects such as iron wire or copper needle can not be used to poke the nozzle to prevent the hole from expanding , Make the spray quality worse; if the filter screen in the casing is blocked or the water valve ball is set up, the filter screen should be cleaned and the dirt that has set up the ball should be cleaned.
The switch leaks or cannot be screwed: if the switch cap is not tightened, the switch cap should be tightened; if the gasket on the switch core is worn out, the gasket should be replaced; the switch cannot be screwed because it has been placed for a long time or has been used for a long time, the switch The core is stuck due to the erosion of the agent, the parts should be removed and cleaned in kerosene or diesel; if it is difficult to remove, it can be soaked in kerosene for a period of time, and then it can be removed after disassembly. Do not hit with hard objects.
Water leakage in each connection part: if the joint is loose, the nut should be tightened; if the washer is not flat or damaged, the washer should be leveled or replaced; if the washer shrinks and hardens, it can be soaked in animal oil before use .
