Everyone can use the metering pump, but if you often use it, have you forgotten to clean it? If not cleaned, the application will be affected.

The manufacturer of metering pump will introduce the cleaning method of metering pump to you in detail. When the metering pump is applied, the connection between the pipeline and the valve shall be maintained regularly to see if there is leakage, and the valve shall be cleaned every 3 months to prevent blockage (the cleaning time can be adjusted according to the characteristics of the drug, for example, the drug with grain size must be cleaned once a month). When the metering pump does not operate for a long time, it shall be cleaned before application.

The whole process of metering pump cleaning:

1. First wash it with clean water for about ten minutes, and then evacuate it for about five minutes. It is obvious that the water in the pipe has been discharged, and the disassembly posture has just begun to reduce the risk

2. Turn off the switching power supply circuit of the metering pump and remove all valves (during disassembly and assembly, pay special attention to the residue of drugs and water to prevent damage or splashing on the switching power supply circuit and other relevant machinery and equipment)

3. Clean the valve and valve parts with clean water

4. Check whether the parts are damaged, deformed, cracked, etc. if so, please disassemble and replace them

5. Reinstall all valves

6. The test shall be carried out according to spraying clean water for five minutes (if there is crystallization, please apply crystalline paint thinner for about ten minutes, and then change to clean water for five minutes).

Friendly reminder from metering pump manufacturer: please wear safety protective clothing (goggles, rubber gloves, etc.) when carrying out cleaning posture; The valve of the metering pump is made of plastic. Please avoid using common tools during disassembly and assembly to prevent damage to parts. Accurately measure the liquid in the certification, which is very volatile; Accurate measurement of certification solution accounts for a large proportion
