Application and Structure of KCB-55 Gear Oil Pump

Application and Structure of KCB-55 Gear Oil Pump

Gear Oil Pump KCB-55 is popular lubrication equipment in the mechanical equipment industry, whose main function is to transport lubricating oil in various mechanical equipment lubrication systems. This gear pump has a wide range of applications and can meet the lubricating oil needs of various types of mechanical equipment.

The structural design of the gear oil pump KCB-55 is simple and scientific, mainly composed of core components such as gears, shafts, pump bodies, and shaft end seals. Gears undergo heat treatment and have high hardness and strength. During pump operation, the gear and shaft are installed together in a replaceable shaft sleeve to ensure stable operation of the pump. In addition, the lubrication of all parts in the pump is automatically achieved using the output medium during pump operation, reducing maintenance costs.

It is worth mentioning that the design of the KCB-55 gear oil pump takes into account the possible torque force that the gear may bear during operation, and particularly sets up oil discharge and return grooves to minimize the torque force that the gear bears during operation, thereby reducing bearing load and wear, and improving pump efficiency.

The KCB-55 gear oil pump has a wide range of applications, especially suitable for conveying lubricating oils with viscosity ranging from 5X10-6 to 1.5X 10-3m2/s (5-1500cSt) and temperatures below 300 ° C. If equipped with copper gears, it can also transport low internal point liquids such as gasoline, benzene, etc. This characteristic enables KCB gear pumps to play an important role in many industries.

To ensure the safe operation of the equipment, the KCB-55 gear oil pump is equipped with a safety valve as overload protection. The total return pressure of the safety valve is 1.5 times the rated discharge pressure of the pump, and can also be adjusted according to actual needs within the allowable discharge pressure range. However, it should be noted that the safety valve cannot be used as a pressure reducing valve for long-term operation. If long-term pressure reduction is required, it is recommended to install a separate pressure reducing valve on the pipeline.

Another highlight of the design of the gear oil pump KCB-55 is that it rotates clockwise when viewed from the extended end of the main shaft towards the pump. This feature enables the pump to better meet the needs of the lubrication system during operation, improving the pump’s work efficiency.

In summary, the gear oil pump KCB-55 has become an ideal choice for mechanical equipment lubrication systems due to its excellent structural design and wide range of applications. In the pursuit of efficiency, environmental protection, and safety today, KCB gear pumps undoubtedly bring good news to many enterprises. Let’s look forward to KCB-55 gear oil pump bringing more breakthroughs and innovations to China’s lubrication equipment market in the future development.
