KCB gear oil pumps are widely used in my country. The structure and design are the products introduced from the Soviet Union in the early 1950s. They have the characteristics of simple structure, practicality, convenient use and maintenance. KCB gear pumps are equipped with valves. When the SS KCB gear oil pumps is overloaded, it will automatically open to protect the motor, but it cannot be used as a normally open overflow valve to adjust the working pressure of the pump. The comparison of KCB gear pumps and YCB gear pump in the scope of application has always been a topic that everyone is very concerned about. The following sai ken pump industry will briefly introduce you:
1. Scope and reasons of KCB gear pump
The internal gear of KCB gear pump is involute helical gear structure. The gear has high hardness and strength after heat treatment. It is installed together with the shaft in a replaceable shaft sleeve to run. The lubrication of all parts in the pump is automatically achieved by using the output medium when the pump is working. There is a reasonable drain and return groove in the pump, which means that the torque of the gear is small during the work, so the bearing load is small, the wear is small, and the pump efficiency is high.
The price of KCB gear pump is moderate, which makes it easier for customers to accept. But the disadvantage is that the wear between the straight teeth is very large, the noise is high, and the service life is shorter. Usually, it is used as a consumable in some working conditions.
2. The practical application and reasons of YCB gear oil pump
YCB type arc gear pump double arc and sine curve compound into a tooth shape, which can completely eliminate the involute gear delivery pump. He has won major scientific and technological achievement projects and won the third prize of scientific and technological progress of the Education Commission. The arc gear is in continuous contact between the two meshing tooth profiles without oil trapping, which completely solves the phenomenon of vibration, noise and increased bearing load of the involute gear pump caused by oil trapping. The gear is manufactured with double arc sine curve tooth shape. Compared with the involute gear, its outstanding advantage is that the tooth profile surface does not slide relatively during the gear meshing process, so the tooth surface is free of wear, smooth operation, no liquid-induced phenomenon, low noise, long life and high efficiency. The pump got rid of the constraints of traditional design, making the gear pump enter a new field in design, production and use. The characteristics of SS YCB arc gear oil pumps are low noise, high pressure, and good energy saving effect. The cost of YCB arc gear pump is higher than that of KCB gear pump, but considering the use effect, the service life is long and the price is higher.
