Internal combustion engine cooling water pumps and their accessories
УРАП Water pump talks about on-site repair knowledge of water pump shaft wear
Abrasion and corrosion of the water pump shaft is an inevitable phenomenon, and there are many ways to repair the abrasion of the water pump shaft, some directly replace the new shaft, some repair welding machine processing, some electric brush plating, some laser cladding and so on.
УРАП Water pump introduces the head knowledge of the pump
The difference between the total energy of the liquid unit at the inlet and outlet sections of the pump is the pump head. The pump head refers to the height of the pumped unit liquid or the energy given to it called the pump head, that is, the work done by the pump on the unit weight of the liquid. It refers to the height at which the pump can lift water and is an important working performance parameter of the pump. Also known as pressure head.
УРАП Water pump tells how to make water pump motor parts
The water pump has motor components to drive the water pump to work. If it is not started for a long time, the equipment is prone to rust, which makes the initial starting torque of the motor rotor shaft large, so the motor current when starting will also be large, which may easily cause the motor to start overload And damaged.
УРАП Water pump talks about several small problems encountered in the use of the water pump
If the pump is unable to pump out the liquid, the pump needs to be refilled if the liquid is not filled.
Г Introduction of A3-52Water pump: How to solve the cavitation of water pump?
Cavitation phenomenon is: when the pump suction vacuum is greater than the allowable suction vacuum, cavitation occurs. It mainly occurs at the outer edge of the impeller blade and cover, the volute or the guide wheel, and does not occur at the entrance of the blade.
What is the reason why the K700 water pump does not fill the water?
The reason will vary depending on the unit, but generally the supply rate and temperature of the water will cause some internal damage.
Д245 Water pump small class explanation: What are the filling methods of the water pump?
Manual water filling method For small pumping stations with the inlet pipe diameter less than 300mm, the inlet valve usually has a bottom valve at the inlet of the inlet pipe.
The river water contains more sediment, which has a greater impact on the characteristics of the centrifugal pump. Due to hydraulic wear and mechanical wear, the flow rate is reduced, the head is reduced, the efficiency is reduced, and the pump characteristic curve changes corresponding to the increase in power.
Д245 Water pump tells how to choose the number of water pumps?
A water pump is a machine that transports liquids or pressurizes liquids.
Д245 Water pump tells how to distinguish true and false pumps?
Some water pumps are refurbished with waste parts. At this time, you can find the old paint after removing the paint on the surface of the parts. Do not use such water pumps.
A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy or other external energy of the prime mover to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid-base liquids, emulsions, suspoemulsions and liquid metals.
MT3 Water pump tells what you need to know during the use of the pump?
If the water pump has relatively minor faults, remember not to let it work. If the packing of the water pump shaft is worn out, it should be added in time. If the water pump continues to be used, air leakage will occur. The direct effect of this is that the energy consumption of the motor will increase, which will damage the impeller.
