Diesel engine fire pump as an important tool for fire fighting and rescue, rescue of life and property, must have a faster reaction rate, especially the diversion time must be very short, so as to reduce the loss to the maximum extent. The time of fire pu
In order to improve the performance of the diesel engine fire pump and prolong its service life, the cavitation experiment of the forest fire pump is designed according to the possible cavitation in the centrifugal pump. The test system is mainly composed
Centrifugal pump impeller, and the general diameter of the front and back cover.
Mixed flow pump impeller back shroud, than the front cover, section view, there is a certain angle.
Fluid flow direction, perpendicular to the fluid flow in the inlet and t
Centrifugal pump is the impeller rotation, the mechanical energy can be passed to the liquid, so that the liquid to obtain kinetic energy, and through the spiral case to the kinetic energy into static pressure liquid conveying machinery. The work principl
Electric high pressure water pump is driven by electric pump, electric high pressure pump is composed of pump body, water pipe, pump seat, submersible motor (including cable) and starting protection devices, etc.. Before using the electric high pressure p
In addition to the selection of a certain number of pumping station, according to the different requirements of the water supply to the water supply reliability, but also need to use a certain number of spare pump. The number of the standby pump should be
1. If the diesel generator is used in indoor, must will exhaust pipe conducting outdoor and exhaust pipe diameter must be greater than the silencer a smoke pipe diameter, pipe elbows should not more than three, to ensure the smooth flow of exhaust gas, a
Water supply pump station is the source of water supply engineering system, water pump station from the pump station (pumping station), two pumping stations (pumping station), pressure pump station, the composition of the pump station.
The way of maintain the diesel engine water pump:
1. Installed correctly,
2. Properly adjust the tightness of the belt,
3. Fill in the lubricating oil in time,
4. Can not plug the overflow hole,
5. And he shall not play the hard knock.
Multistage pump for diesel engine with diesel engine as a driving force, pump group through elastic coupling driven by diesel engine, with advanced and reasonable structure, high efficiency, cavitation performance, small vibration, low noise, smooth opera
1. The unique single or double vane impeller structure, can greatly improve the ability through the dirt, can effectively of the pump diameter of 5 times the fiber material and a diameter of approximately 50% of pump diameter solid particles.
Went to the agricultural irrigation time, to help broad farmer friend make good use of the mixed flow pump, we sort out 7 details, if farmers do the seven details of the work, I believe that not only can extend the service life of the mixed flow pump, but
Generally speaking, used for irrigation and drainage of the pump, commonly used in the centrifugal pump, axial flow pump, mixed flow pump, water turbine pump, long shaft pump, submersible pump, etc.. But the most widely used axial flow pump and mixed flow
Household water well pump what best, self suction pump in vertical height 1 meter level the length of the longest can also pick up a long tube to suck out the water to, there is no a pump motor at home, 40 meters wells in pipe water pump to spare to.
Axial flow pump is a high specific speed of the pump, generally more than the speed between 500 ~ 1000. Because of the greater the speed, the lower the head, the greater the flow. Because the qv-H performance curve of the axial flow pump is very steep, th
Cast iron/SS bule 4" 6" 7" 8" 10" 12" QJ submersible multistage deep well pump
Diesel engine fire pump group, such as the automatic control of the fire pump group, in the heat exchange pipe to add a solenoid valve and valve in parallel. Under nor
Diesel fire pump engine cooling using dual closed loop heat exchanger cooling system. The system has advantages of high cooling efficiency and less impact on the environment temperature in the pump room. Cooling water flow, from the water pump outlet pipe
Single level direct vortex pump is for pumping water or the physical and chemical properties similar to liquid water, using liquid temperature does not exceed 60, commonly used in boiler water supply facilities and in shipbuilding, textile, chemical indus
Single stage vertical centrifugal pump for vertical structure, import and export of the same caliber, and is located in the same center line, can be installed in the pipeline as the valve, compact and beautiful appearance, small occupation area, low const
