NYP series high viscosity internal tooth pump is the most suitable for conveying high viscosity material. Its structure is more reasonable than the general gear pump, which belongs to the internal meshing internal tooth pump. The main working part of the high viscosity pump is the outer rotor and the inner rotor with inner teeth. The rotor structure is a cycloid with less tooth difference, and the tooth shape of the rotor is the internal equidistance curve of the short outer cycloid.

Compared with the structure of the cycloid rotor with one tooth difference, it is not easy to kill the bites.

The gear pump and the screw pump are generally used as high viscosity pumps, and their working principles are similar, all of which are conveyed by the volume change in the pump. The working part of the gear pump is the gear, the working part of the screw pump is the screw, and it can also be called the rotor. So the two pumps can also be a rotor pump. The highest viscosity of the high viscosity pump can reach 1000000 CIS.

Of course, when a high viscosity pump works in a pipeline, it depends not only on its own performance but also on the performance of the pipeline system. The two are combined to determine the working conditions of the pump in the pipeline system.

The principle of CYZ series self suction centrifugal pump is to use the centrifugal force of the impeller to carry out the liquid. The viscosity of the liquid has a vital effect on the performance of the CYZ series self suction centrifugal pump.

When the viscosity of the liquid is large, the loss of hydraulic friction increases, and the effect of centrifugal force is difficult to be used normally. The flow and lift of the centrifugal pump will all be affected by its influence. The input power of the centrifugal pump increases and the efficiency of the pump is reduced. Therefore, the centrifugal pump is not suitable to be used as a high viscosity pump.

Therefore, the CYZ series self suction centrifugal pump can not be used as a high viscosity pump, that is, the centrifugal pump is not suitable for transporting high viscosity materials.
