The mechanical diaphragm metering pump is a common industrial pump used to transport a variety of liquids. It has the characteristics of stable volume, wide flow adjustment range, pump head will not leak, etc., and is widely used in chemical, pharmaceutical, food processing and other fields. The following is the use of mechanical diaphragm metering pump and precautions.

First, the use of mechanical diaphragm metering pump

1. Preparation Before installation: Before installing the mecha nical diaphragm metering pump, check whether the pump body, valves, and pipes have impurities to ensure a clean installation environment. At the same time, check whether the inlet and outlet of the pump are properly connected to the pipeline.

2. Liquid transportation: Set the flow control valve of the metering pump according to the required flow rate. Open the inlet valve, so that the medium is sucked through the pump, and then flows through the valve and the pipeline to the place where it needs to be transported. Note that different liquids need to choose different valve materials to ensure the stability and safety of transportation.

3. Flow regulation: The flow of the mechanical diaphragm metering pump can be achieved by adjusting the flow control valve. Turning the valve counterclockwise increases the flow rate, while turning it clockwise decreases the flow rate. In actual operation, the flow rate can be adjusted as needed to meet production requirements.

4. Liquid circulation: The mechanical diaphragm metering pump can achieve liquid circulation by reversing operation. When it is necessary to circulate the liquid to the storage tank or other container, it is only necessary to swap the inlet and outlet lines.

5. Maintenance: Regularly check the various parts of the mechanical diaphragm metering pump, such as pump body, valves, diaphragms, etc., are damaged and need to be replaced. At the same time, clean up the impurities in the pump body and pipeline in time to maintain the normal operation of the pump.

Second, mechanical diaphragm metering pump precautions

1, liquid selection: Before using the mechanical diaphragm metering pump, it is necessary to carefully select the liquid. Consider the chemical properties of the liquid, viscosity, temperature and other factors, choose the appropriate pump material, sealing material and valve material. Avoid using liquids that corrode or damage the pump material.

2, the operating environment of the pump: the use of the mechanical diaphragm metering pump environment should be kept dry, free of corrosive gases and combustible gases. Avoid use in high temperature, high humidity, dust and corrosive gases.

3, correct operation: when using the mechanical diaphragm metering pump, it is necessary to operate correctly to prevent errors or accidents. Operators should be familiar with the use of mechanical diaphragm metering pumps and the structure of the equipment.

4, operation status monitoring: regularly monitor the operating status of the mechanical diaphragm metering pump, including flow, pressure and other parameters are normal. Once abnormal conditions are found, it is necessary to stop the maintenance in time.

5. Pump maintenance: regularly check the various parts of the pump, such as diaphragm, seals, valve stem, etc., are worn and need to be replaced. At the same time, clean the impurities in the pump body and pipelines, keep them clean, and avoid blockage and increased resistance.

6. Storage and storage of the pump: if the mechanical diaphragm metering pump is not used for a long time, the medium in the pump body and pipelines needs to be cleaned and stored in a dry and ventilated place. Anti-rust agent can be added appropriately to avoid rust or damage to the surface of the pump.

In short, the use methods and precautions of mechanical diaphragm metering pumps are very important to ensure normal operation and extend service life. Mechanical diaphragm metering pumps can only be used if they are properly operated and maintained.
