The sprayer is a major plant protection machine and many failures occur after a period of use. Every year, there are always a lot of farmers carrying sprayers to overhaul agricultural stations. Its common faults and overhaul methods are described below, hoping to help the majority of farmers. Do not spray continuously evenly. Cause: When the pump was started, the switch was not closed, leaving the air chamber full of liquid and no compressed air. Repair: Remove the air chamber, pour the liquid, close the switch, and re-pump the air so that the air in the air chamber is expelled. Leakage. Cause: Leakage around the piston rod on the pump cap. Repair: If the liquid exceeds the safe water level, the excess liquid should be poured out below the safe water level. If the felt or felt under the pump cover is damaged, it should be replaced. No fog can be sprayed. Causes: nozzle hole, nozzle blockage; switch's dirty water circle damage or leakage network damage; due to serious wear and tear of the ball valve leads to lax close.

This chemical product does not require a production license for medicines, and can be produced in ordinary chemical plants. As long as it reaches a certain level, it can be used for the synthesis of medicines.
