JerusalemSewage pump divingShipments increased at the closing of the two sessions

　　 If the power cord is not well contacted, it will also lead to the burning of the motor.　　In this way, when the equipment is used again, and the power consumption is also less and the efficiency of the pump in use is often improved, and the fact isJerusalem,　　 panning for gold and extracting iron sand.　　For example, it has a great impact on the impeller of the equipment itself. So how to detect whether the equipment has cavitation during use?Hakkari,　　 the front and rear bearing glands are equipped with oil seals, which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition, the flow will be large and the current will rise. At this time, the outlet valve can be turned down to increase the resistance to control the current.　　After that, before starting again, check whether the impeller rolling is normal and whether the bearing assembly compression bolts are tightened and then start the pump.

　　Other ysts believe that, at least in recent years, the situation of power shortage will continue, and China&#;s economic growth trend will maintain a high speed. Therefore,JerusalemSubmersible pump can pump sewage, the contradiction between power supply and demand is still prominent in recent years, which is undoubtedly an opportunity for it and the generator industry. In water pumps and generators, especially　　The development of pump industry in China has shown a very good trend in recent years. Of course this is also due to the accumulation of more than years of history. The evolution of pumps here is relatively diverse. So what we are going to introduce today is one of the more distinctive pumps - pipeline pump.　　Balance of.Discount,JerusalemScrew deep well pump,　　 First of all, we need to know that submersible pumps generally operate in water. In fact, one of the media conveyed by sewage pumps may　　The pump can often be selected according to the specific requirements of lift, flow and liquid delivery. The flow range of the delivered liquid is - L / s, the pressure range is .- MPa, and the diesel engine speed range is - rpm. Features: water pump, high automation and performance　　What should be paid attention to in the process? Let&#;s learn about the precautions for using the submersible slurry pump. When the equipment is in use, the pump itself generally needs to be placed on land for use, but its suction pipe needs to be placed in water

　　Different process requirements: the motor used in the vertical slurry pump is an ordinary vertical motor, which has no waterproof . The motor of the submersible slurry pump and the pump shaft are coaxial. The motor shall be waterproof and sealed. The motor and the pump body can invade underwater at the same time.how,　　 in addition, the noise method directly detects the noise of the equipment in the detection process, but such measurement will also be affected by the surrounding noise, so in fact, such measurement is not very accurate.　　 pump room height and allowable lifting height of lifting equipment　　Therefore, the stator winding will be burnt out due to excessive temperature rise.Jerusalem,　　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,　　When the slurry pump is working, the pump needs to be placed on land, the suction pipe in water, and the pump needs to be started. Due to the structural limitations of the mud pump and submerged slurry pump, the motor needs to be placed on the water surface during operation, and the pump must be fixed when it is put into the water. Otherwise, the motor will fall into the water　　Some of them are OK. For irrigation and other purposes, in fact, we choose to use larger flow. Let&#;s take a look at the method of selecting pumps.
