2cy series marine gear pumps are mainly composed of gears, shafts, pump bodies, relief valves, and shaft end seals. The gear has a higher hardness and strength after heat treatment, and is installed in a replaceable sleeve together with the shaft to run. The lubrication of all parts in the KCB gear oil pump is automatically achieved by using the output medium when the pump is working.　　There are reasonably designed oil drain and oil return grooves in the pump. The gears bear low torque during work, so the bearing load is small, the wear is small, and the KCB gear oil pump has high efficiency. 【High Pressure Gear Pump】　　2cy series marine gear pumps are equipped with an overflow valve as overload protection. The total return pressure of the overflow valve is 1.5 times the rated discharge pressure of the pump. The KCB gear oil pump can also be adjusted according to actual needs within the allowable discharge pressure range. But note that this overflow valve cannot be used as a long-term pressure reducing valve, and can be installed on the pipeline when necessary.　　 Looking at the pump from the extended end of the main shaft, it rotates clockwise.

Causes of seal damage of multistage vacuum pump There are two kinds of reasons for the seal damage of multistage vacuum pump: artificial damage and natural damage. The seal of multistage vacuum pump will be damaged by scratch, bruise and squeeze when it is opened and closed. Mechanical damage between two sealing surfaces. Under the action of high temperature and high pressure, atoms permeate each other and cause adhesion. When the two sealing surfaces move with each other, the adhesion is easily pulled and torn. The higher the surface roughness of the sealing surface of the multi-stage vacuum pump, the more easily this phenomenon occurs.When the medium is active, the sealing surface of multi-stage vacuum pump is worn, washed and cavitated. The floating fine particles in the medium collide with and offend the sealing surface, causing local damage. The high-speed moving medium directly washes the sealing surface, causing local damage. When the medium is mixed and vaporized locally, the gas generating bubble blasting impacts the sealing surface, causing local damage. Medium erosion and chemical erosion alternate action, will strongly erode the sealing surface.The potential difference and electrochemical corrosion will occur due to the contact between sealing surfaces, the contact between sealing surfaces and sealing body and valve body, as well as the concentration difference of medium and oxygen concentration, which will lead to the corrosion of sealing surface on the anode side. However, in the case of no current generated by the medium near the sealing surface, the medium directly reacts with the sealing surface, forming chemical erosion and eroding the sealing surface.Industrial craneRoots BlowersRoots Vacuum Pump

Skeleton Seal: it is a kind of self tightening lip seal with simple structure, small size, low cost, convenient maintenance and small resistance torque. It can not only prevent medium leakage, but also prevent the invasion of external dust and other harmful substances, and has certain compensation ability for wear, but it is not resistant to high pressure. Therefore, it is generally used in gear oil pump of low pressure occasions, such as KCB series gear oil pump, 2CY Series gear oil pump. Gasket seal: gasket is the basic component of static seal of centrifugal pump, which is widely used. The selection of gasket is mainly determined by the factors such as conveying medium, temperature, pressure and corrosivity of chemical pump. It is mainly used for sealing the pump body of Y-type centrifugal pump, mostly made of aluminum sheet.
