Diesel engine double suction centrifugal pump (S-type) product introduction:

The diesel engine double suction centrifugal pump is a new type of diesel engine water pump that uses a high-power diesel engine to drive an S-shaped double suction centrifugal pump. The product has the characteristics of high flow rate, high head, and high efficiency The product is designed according to national standards and specifications, with a high degree of serialization, standardization, and universality. This type of pump has advanced performance, stable operation, safety, and reliability. It uses a new imported hydraulic model and is forged with various new materials, which can meet the transportation of various media.

Diesel engine double suction centrifugal pump (S-type) is mainly used for conveying liquids in water plants, air conditioning circulating water, heating pipeline systems, building water supply, irrigation, drainage pump stations, power plants, industrial water supply systems, fire protection systems, shipbuilding industry, mining water supply and drainage, etc. The medium is suitable for conveying clear water or liquids with physical and chemical properties similar to water.

The main features of a dual suction centrifugal pump for diesel engines are:

The main components of the pump are:; Pump body, pump cover, impeller, shaft, double suction sealing ring, shaft sleeve, etc. Except for the high-quality carbon steel material used for the shaft, the other main components are made of cast iron, cast steel, and stainless steel.

The pump body and pump cover form the working chamber of the impeller, and there are pipe screw holes for installing vacuum and pressure gauges on the inlet and outlet flanges. The lower part of the inlet and outlet flange is equipped with threaded holes for water discharge pipes.

The impeller that has undergone static balance inspection is fixed on the shaft with a shaft sleeve and two side shaft sleeve nuts, and its axial position can be adjusted through the shaft sleeve nuts. The axial force of the impeller is balanced by the symmetrical arrangement of its blades and the inflow of water on both sides.

The pump bearing is a radial ball bearing. The bearings are installed inside the bearing body and at both ends of the pump body, lubricated with butter.

The double suction sealing ring is used to reduce water leakage from the pressure chamber of the water pump back to the suction chamber.

The pump is directly driven by an electric motor through an elastic coupling, and can also be driven by an internal combustion engine if necessary.

The shaft seal is a soft packing seal (machine seal can also be installed as needed). In order to prevent air from entering the pump and cooling the lubrication sealing chamber, packing rings are installed between the packing materials. During the operation of the water pump, a small amount of high-pressure water flows into the packing chamber through the trapezoidal groove on the opening surface of the pump cover, providing a water seal.
