As the fluid precision measurement and the ideal dosing equipment, metering pump has been widely used in various fields including water, food and beverage industry, pharmaceutical and petroleum chemical industry, and in the measurement process bears a strong corrosive, toxic, high viscosity and high pressure medium added task. But when we are in the process of using, we often appear the situation that the metering pump can not get the liquid medicine. Now, the Xiaobian of Huaian branch diaphragm pump manufacturer, koyu machinery, summarizes the reasons and treatment methods for you.

1. filter is blocked with the tube of the medicine.

2. the ball valve of the drug intake and the outlet of the drug is blocked by foreign objects.

The sealing of the ball valve of 3. inlet and outlet is not good, and gas leakage.

The ball valve is swirled several times to make it close to the base.

4. loose or shedding of the sealing ring of the inlet and outlet

Treatment: check if the seal ring of the pump is all installed.

5. pump head produces liquid release or diaphragm breakage

Treatment: the diaphragm is damaged, the new diaphragm is replaced, replaced, and reinstalled.

The 6. connecting rod group dies.

Treatment methods: one is the maintenance of the rod group parts apart, rusty parts with file plus lubricating oil can be removed or replaced; new linkage.

The 7. motor burned out.

Treatment: replace the new one.

8. adjust the cam to the "0" position, the flow is zero and can not make the water.

Processing method: adjust the cam adjustment to make its scale not 0.

9.AKS603 traverse.

Processing method: horizontal is not playing drops, it must be placed vertically. So the sealing ability can achieve good effect.
