Head refers to the energy obtained from the pump by the unit weight of liquid output by the pump, so head refers to the effective energy obtained from the liquid output by the pump in unit time - that is, the effective power of the pump: the equation is PE= ρ GQH (W)= γ QH (W)　　There is no need to equip auxiliary mixing or spraying equipment, and the operation is simpler. The equipment is directly submerged for operation, without noise and vibration, and the site is cleaner.Patulur,　　 Determination of lift　　Pump, sewage submersible pump and seawater submersible pump.Hajin　　About %), and motor power p=i × U indicates that high power and current will increase.　　Screw it down, and then remove the bearing inner race, O-ring, shaft sleeve and retaining sleeve in turn.　　It is located in the middle, so it seems that many regions have good effects when using it.

　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressure　　 sedimentation tanks, hydropower stations, reservoirs,PatulurWQ submersible pump parameters, rivers, power plants, open caissons, mines and fish ponds.　　Flexibility. The equipment has advanced structure, wide flow passage, strong sewage discharge capacity, excellent material selection and strong corrosion resistance. It is suitable for conveying liquids containing solid particles, cinder and tailings. So what are the requirements for its work? Let&#;s understand briefly.build,PatulurSmall deep well pump,　　If the pressure in the local area is equal to or lower than the vaporization pressure corresponding to the water temperature in the flow process, the water will vaporize there and form many small bubbles mixed by steam and gas. The cavitation phenomenon is due to the bubble action when these small bubbles flow from the low-pressure area to the high-pressure area in the water pump,　　According to the user&#;s requirements, the motor can add a variety of protection devices such as water inflow detection and overheating, so that the product can operate safely for a long time under adverse working conditions.　　There is a difference between submersible slurry pump and sewage pump. Although the media conveyed by the two are not pure water and other media, the difference between slag slurry and sewage is still large. Let&#;s take a look at the difference between the two.

　　 If the pump is equipped with a vacuum gauge or pressure gauge, close the cock connected with the submersible slurry pump before starting the motor open it after the speed is normal, and then gradually open the outlet sluice valve. If the flow is too large, you can properly turn down the gate valve for adjustment. Otherwise, if the flow is too small,Open the gate valve.Information recommendation,　　This phenomenon shows that the failure of the pump is not only a material problem, but also reminds the pump designers and producers that in addition to good working conditions, the pump should also have good corrosion resistance, high reliability and long service life. The pump shall be designed in addition to the conventional design method of fluid mechanics　　Functions of cf fire control cabinet: Strengthen management. Normally, the use and daily management of fire pumps require manual operation, once large shopping malls are encountered and there are a large number of similar fire pumps,　　There is no need to equip auxiliary mixing or spraying equipment, and the operation is simpler. The equipment is directly submerged for operation, without noise and vibration, and the site is cleaner.Patulur　　It is located in the middle, so it seems that many regions have good effects when using it.　　The high-efficiency slurry pump has three characteristics: first, the slurry pump has high operation efficiency and low loss.　　The disc friction loss of the slurry pump impeller will decrease with the decrease of the impeller diameter, so that the pump efficiency of most low specific speed pumps will improve slightly after the impeller is cut. After cutting, keep the blades overlapped to a certain extent, and the degree of blade overlap will decrease with the addition of specific speed
