According to different working principles and structural characteristics, metering pump manufacturers can classify metering pumps into plunger pumps, gear pumps, screw pumps, and other types. The plunger pump compresses and delivers liquid by reciprocating the plunger in the cylinder body; Gear pumps achieve fluid transportation through the meshing between gears; The screw pump pushes the liquid out through the movement of the screw in the spiral groove. Different types of metering pumps are suitable for different work scenarios, and the appropriate type can be selected according to specific needs.

When using a metering pump, the following points should be noted: choose the appropriate metering pump model and specifications according to actual usage requirements; Secondly, it is necessary to regularly inspect and maintain the metering pump to ensure its normal operation; Again, it is necessary to operate the metering pump correctly according to the operating instructions to avoid equipment damage caused by misoperation; Pay attention to the safety of the metering pump to avoid leaks or other accidents.

What are the tips for daily cleaning and maintenance of metering pumps introduced by metering pump manufacturers?

Clean the external surface of the metering pump. During the use of the metering pump, it is inevitable to be contaminated with some dust and dirt, so it is necessary to regularly wipe the external surface of the metering pump with a clean damp cloth or soft brush to maintain a clean and tidy appearance.

Secondly, clean the internal components of the metering pump. After long-term use, liquid residues and impurities inside the metering pump can affect its normal operation, so it is necessary to regularly clean the internal components, especially key components such as the pump body and valves. Professional cleaning agents and soft brushes can be used for cleaning to ensure smooth internal passages.

Once again, lubricate the key components of the metering pump. The metering pump requires lubricants during operation to reduce friction and wear, improve pump efficiency and lifespan. Therefore, after cleaning the internal components, it is necessary to regularly add an appropriate amount of lubricating oil to key components such as hydraulic cylinders and actuators to ensure the normal operation of the pump.

Check the sealing and connecting components of the metering pump. The sealing and connecting components of the metering pump are key factors for the normal operation of the pump. If oil leakage, liquid leakage or looseness is found, it needs to be repaired or replaced in a timely manner to prevent leakage and malfunction.

The metering pump transports fluid from one location to another through pressure or volume, accurately controlling the flow rate and pressure of the fluid, ensuring the stability and accuracy of the production process. In the pharmaceutical industry, metering pumps are widely used to transport various drugs and drug mixtures, such as physiological saline, drug solutions, recombinant proteins, etc. The metering pump can accurately control the flow and pressure of the medication, ensuring precise delivery and stability of the medication.

Metering pumps are widely used in chemical, pharmaceutical, food, medical and other fields. In the field of chemical engineering, metering pumps are used for batching, conveying corrosive liquids, chemical reagents, etc; In the pharmaceutical field, it can be used for drug formulation and infusion control, etc; In the food industry, it can be used for accurate transportation of juices, beverages, dairy products, etc; In the medical field, metering pumps are commonly used for operations such as infusion and injection. Metering pumps play an irreplaceable role in these fields, improving production efficiency and product quality.
