Structural characteristics and technical parameters of diesel engine water pumps. Diesel engine water pumps are widely used and are also suitable for general use in urban water supply, large-scale water conservancy projects, farmland irrigation, drainage, drainage pumping stations, power plants, mines, industrial water supply systems, air conditioning systems, fire protection systems, shipbuilding industry, and oil refining industry. Then, the following introduces the structural characteristics and technical parameters of diesel engine water pumps.
Description of the structural characteristics of diesel engine water pumps:
1. Compared with other similar pumps, diesel engine water pumps have the characteristics of long life, high efficiency, reasonable structure, low operating cost, and convenient installation and maintenance. Because it is open in the middle, there is no need to remove water during maintenance. The oil outlet pipeline and the motor (or other prime mover) are viewed from the coupling to the pump. The air inlet and oil outlet of the diesel engine water pump are both located below the axis of the water pump, and the horizontal direction is perpendicular to the axis, which is the pump shell. , The water pumps rotate in the direction of the anti-dimension needle.
2. The materials of diesel engine water pump include copper, cast iron, ductile iron, 316 stainless steel, 416 rust steel, monel alloy, titanium alloy and No. 20 alloy. The other main components of diesel engine water pump are pump body, pump cover, impeller, shaft, double suction seal, sleeve, bearing, etc.
3. The pump body and pump cover form the impeller studio. The inlet and outlet flanges are provided with pipe thread holes for installing vacuum gauges and pressure gauges, and the lower part of the inlet and outlet flanges is provided with pipe thread holes for draining water.
4. The hydraulic design of the impeller adopts advanced CFD technology. Its axial position can be adjusted with boss nuts. The axial force of the impeller is balanced with the symmetrical configuration of the blades, which improves the hydraulic efficiency of the diesel engine water pump. The impeller is fixed on the shaft with bosses and boss nuts on both sides after static balance detection. The remaining axial force may be borne by the bearings at the coaxial end.
5. The pump shaft of the diesel engine pump is supported by two sets of rolling bearings. The design life of the bearings is more than 100,000 hours. Double-row thrust bearings and closed bearings can also be used. Installed at both ends of the pump body. According to the unique bearing body design, the bearing can be lubricated with grease or thin oil. The diesel engine water pump is directly driven from the motor through an elastic pin coupling or a metal laminated coupling. The pump body is equipped with a double suction seal, which is easy to disassemble and replace. The driving machine can also be an internal combustion engine or a gas turbine.
6. The diesel engine water pump shaft sleeve is made of a variety of different materials. The wear ring pump body and the impeller are equipped with a replaceable wear ring to prevent the corrosion and wear of the shaft. The shaft sleeve can be replaced to prevent the pump body and the impeller from wearing. The replacement is convenient and the maintenance cost is low, while ensuring the running clearance and high working efficiency.
7. The diesel engine water pump shaft seal can be sealed with packing or enter the shaft seal chamber through an external cooling water pipe. It is not necessary to remove the water pipe and the motor for inspection, which is convenient for maintenance and can also be sealed with a machine. The shaft seal cooling flushing water can enter the shaft seal chamber through the groove on the opening surface of the pump cover. The structural size of the pump can be changed according to the needs of the user.
