Everyone can use a hydraulic metering pump, but if you use it often, do you forget to clear it? If not cleaned, it will harm the application.

When the hydraulic metering pump is applied, the connection between the pipe and the valve should be maintained for leakage, and the valve should be cleaned every 3 months to avoid blockage (the cleaning time can be adjusted according to the performance of the drug, for example, the application of thermal expansion drug at least once a month as far as possible). When the metering pump is not running, it should be cleaned before application.

Hydraulic metering pump cleaning the whole process:

1. First clean with water for about ten minutes, and then empty yourself for about five minutes, it is remarkable that the water in the tube has been drained, and the disassembly state initially reduces the risk

2. Turn off the switching power circuit of the hydraulic metering pump and remove all the valves (when disassembling and assembling, still pay attention to the remnants of drugs and water as much as possible to avoid damaging or splashing the switching power circuit and some other mechanical equipment and causing harm).

3. Clean the valve and valve parts with water

4. Check whether the parts are damaged, deformed, split, etc. If so, please carry out disassembly and replacement

5. Reinstall all valves

6. Test according to spraying water for five minutes (if there are crystals, please apply crystal paint thinner for about ten minutes, and then change to water for five minutes).

Friendly tips from metering pump manufacturers: When cleaning, please wear safety factor protective clothing (protective glasses, rubber gloves, etc.); The valve of the metering pump is made of plastic. Avoid using special tools during the disassembly and assembly period to avoid damaging parts. The liquid in the accurate measurement verification is very easy to evaporate; The proportion of accurate measurement verification liquid is very large; When a large number of four-stroke frequencies are necessary; When the metering pump is working in the plateau area; When used in the field, it is necessary to have a large storage tank, and in cases where natural suction is not possible, the metering pump can be used, in which case it can fill the suction pipe.
