Most of the metering pumps on the market now use ordinary pump heads. It is produced by processing PVC round rods on a lathe. The places where the ball valves are released at both ends can only be connected by internal and external threads. The larger the thread, the greater the thickness of the round bar will be, and the increased cost will double. Domestic production of PVC round rods over 300 millimeters is almost impossible. The price of imported products from Germany is more than twice that of domestic ones. The thinner the round bar is, the lower its cost will be, but its strength will also be poorer. The result is that the pressure borne by the pump head is not high. The metering pump operates in a pulse mode, with significant impact force and buffering force. Therefore, the connection parts of the pump head are prone to breakage and leakage, which greatly reduces the service life of the metering pump.

	The metering pump of our company uses an integrated pump head. The production process involves making plastic molds and then using the molds to produce pump heads. The entire pump head is of an integrated structure. For the consideration of strength, the external thread can be infinitely enlarged. The pump head injection mold can adopt the material removal method, and the additional cost will not be too much. In this way, the pressure that the pump head can withstand can reach a very high level. Moreover, the pump head is extremely sturdy, with a strength more than twice that of an ordinary pump head. There will be no situation of fracture or leakage, which greatly increases the service life of the metering pump.

The turbine rod was the first generation of deceleration method in the 1950s and 1960s. Disadvantages: ① It cannot operate without oil ② The turbine is prone to wear ③ Low transmission efficiency ④ Poor impact force Advantage: Low cost

	The commonly used reduction method for reducers with a ratio of 30 or less currently available on the market. This type of reducer has no problem when used in transmission with uniform force. However, the metering pump is subjected to single-point impact force, so the requirements for bearings and gears are relatively high. If it is two-stage deceleration, the bearing and the gear each bear 50% of the force

To enhance the performance and quality of our products, our company has collaborated with a reducer motor manufacturer to develop a three-stage reducer motor with a ratio of 10 to 25. The force on the bearings and gears has been reduced from 50% to 33%, which has prolonged the service life of the bearings and gears in the reducer. At the same time, all the original reduced frames were changed to raised frame reduction motors. By now, the service life of the transmission parts of our company is at least 10 years or more.
