When using stainless steel metering pump often have traffic, it is a common problem, need not too much panic, mechanical diaphragm metering pump manufacturers division building remind you that this time should be to analyze the reason, to find the problem.

Here are the reasons for the lack of flow of the stainless steel metering pump:

1. When the stainless steel metering pump has no flow, it should first check whether the oil level of the stainless steel metering pump is normal and the oil is spoiled. If the oil is spoiled or oil deficient, fill in the oil in normal or replace the hydraulic chamber.

2. Check the export safety valve.

The export safety valve of the stainless steel metering pump often shows no return or leakage, causing the pump outlet pressure not to rise, and no flow. This can be solved by simply rechecking the relief valve.

3. The diaphragm.

Check the pressure of the pressure gauge mounted on the pump head. In general, the pressure gauge of the stainless steel metering pump is zero. If there is pressure to indicate that the diaphragm may be damaged, replacing the diaphragm will solve the problem.

4. Check the double function hydraulic valve of stainless steel metering pump.

The pressure of the valve is not allowed to cause leakage, which can affect the pressure of the hydraulic chamber, which can not lift the outlet pressure. This pump has appeared on several occasions during operation. Replacing this valve or rechecking the valve can be solved.

5. Check the oil filling valve.

The setting value of the oil filling valve is inaccurate, which directly leads to the hydraulic fluid entering the hydraulic chamber, resulting in the lack of oil in the hydraulic chamber, resulting in no discharge. Readjust the spring elongation of the filling valve.

6. Check the inlet valve.

There are foreign objects in the one-way valve of the entrance, which can cause the wear of the sealing surface, resulting in poor sealing effect. There is no flow when there is flow.

7. Check whether the entry filter is blocked.

The inlet filter is blocked, which causes low pressure on the suction inlet of the pump, resulting in less flow and not even.
