The high-pressure diesel water pump is composed of a diesel engine and a high-pressure multi-stage centrifugal pump. The pump group is in the form of a horizontal, single-suction, multi-stage centrifugal pump. It has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. For conveying clean water or other liquids with physical and chemical properties similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material of the pump flow parts, the sealing form and increasing the cooling system. The axial force is balanced by the balance disc. Shaft seals generally use packing seals, and mechanical seals can also be used according to user needs.
Conditions of Use
1) Ambient temperature≤50℃, medium temperature≤80℃, 2) The weight of the medium does not exceed 1240kg/m3. 3) The liquid level must be higher than the water inlet of the pump, and idling without liquid is prohibited.
It is suitable for mine drainage, industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire pressurization, high mountain long-distance water supply, heating, bathroom and other cold and warm water circulation pressurization and equipment matching.
Working Principle
The driver drives the impeller to rotate through the pump shaft to generate centrifugal force. Under the action of centrifugal force, the liquid is thrown to the outlet of the impeller along the blade flow channel, and the liquid is collected by the volute and sent to the discharge pipe. The liquid obtains energy from the impeller, which increases both pressure energy and velocity energy, and relies on this energy to transport the liquid to the work site. When the liquid is thrown to the impeller outlet, a low pressure is formed at the center of the impeller inlet, and a pressure difference is generated between the liquid suction tank and the liquid at the center of the impeller. It continuously enters the impeller through the suction pipeline and the suction chamber of the pump.
Advantages
1. Advanced hydraulic model, high efficiency and wide performance range.
2. The pump runs smoothly and has low noise.
3. The shaft seal adopts soft packing seal or mechanical seal, the seal is safe and reliable, the structure is simple, and the maintenance is convenient and quick.
4. The shaft is a fully sealed structure, which ensures no contact with the medium, no rust, and long service life.
