KCB, 2CY type gear oil pump

KCB, 2CY type gear pump is equipped with a pair of rotary gears in the pump body, relying on the mutual meshing of the two gears, the entire working chamber in the pump is divided into two independent parts. When the pump is running, the active gear drives the passive gear to rotate, and when the gear is out of mesh, a local vacuum is formed on the suction side, and the liquid is sucked. The inhaled liquid fills each tooth valley of the gear and is brought to the discharge side, and the liquid is squeezed out of the pump when the gear enters the mesh.

● Suitable for conveying a variety of lubricating liquids, the temperature is not higher than 70℃, if the need for high temperature 200℃, contact with the unit can be equipped with high temperature resistant materials, viscosity of 5×10-5 ~ 1.5×10-3m2/s.

● Not suitable for conveying corrosive, containing hard particles or fibers, highly volatile or low flash point liquids, such as gasoline, stupid, etc.

It is composed of parts such as pump body, gear, front and rear pump cover, safety valve, bearing and sealing device.
1. Pump body.

The front and back covers and other parts are gray cast iron, and the gear is made of high-quality carbon steel. Can also be made of copper or stainless steel according to user needs.
2. Safety valve.
2CY type gear oil pump itself does not have safety valve, the user needs to install safety valve in the pipeline system. KCB, 2CY type gear oil pump is equipped with safety valve above the rear pump cover or pump body, when the pump or discharge pipe fails or
When the discharge valve is completely closed and the high pressure and high pressure shock are generated, the safety valve will automatically open and remove part or all of the high pressure liquid back
To the suction cavity, so as to play a safety protection role for the pump and pipeline.
3. Bearing.
2CY gear oil pump all use DU bearings; Tin bronze bearing can be used according to user requirements. &0818.3-83.3, 2CY1.1 gear type oil pump using DU bearing; Tin bronze bearing can be used according to user requirements.
KCB133-960, 2CY8-60 gear type oil pump adopts DU bearing, tin bronze bearing and rolling bearing three structures, need to be indicated when ordering. Those not specified when ordering are supplied according to DU bearing structure.
The bearing is a built-in type, relying on the transport medium for lubrication; 011 bearings and tin bronze bearings can work in non-lubricating media.
4. Shaft seal.
The shaft end seal of this series of products has three structures: skeleton oil seal, mechanical seal and packing seal.
a. Skeleton oil seal: skeleton oil seal is characterized by easy maintenance and replacement, low cost, but short life. Ding Qing rubber skeleton oil seal is suitable for 1001: the following working environment; Fluororubber skeleton oil seal is suitable for working environment below 200℃.
b.1 Mechanical seal: Mechanical seal is characterized by reliable sealing, long life and high cost. The matrix of the mechanical seal is made of stainless steel, and the dynamic and static circumferential media are different, respectively, made of YG8 carbide or YG8-graphite, and the use temperature is below 200℃.
c. Packing seal: Packing seal is only used for high temperature oil pump, which is characterized by high temperature resistance and a small amount of leakage. During use, it is necessary to adjust frequently according to the leakage situation, and the use temperature is below 250℃.
The type of sealing structure required by the user should be indicated when ordering. Where the order is not indicated, the supply is according to Ding Qing rubber skeleton oil seal structure.
5. Type of inlet and outlet:
The inlet and outlet of the 2CY gear oil pump are British pipe threads (G) corresponding to the diameter, which are directly made on the pump body.
KCB18.3-200, 2CY1.1-12 gear type oil pump is equipped with waist flange with pipe thread opening; Other pumps are not equipped with flanges, when the user needs to be equipped with flanges, should be indicated in the order.
6, the pump and the motor are connected with an elastic coupling and installed on the public chassis.
