when the temperature rises to a certain value

　　Only in this way can its service life be extended to a large extent.　　Cavitation of the pump is caused by water evaporation of the pump. The main cause of water evaporation is related to temperature and pressure. Under a certain pressure, the water begins to vaporize and change from liquid to gas. On the contrary, at a certain temperature, the pressure drops toFantino,　　 the resistance shall be greater than megohm after filling with water. Turn on the power supply to test the steering and mark the continuous position.　　 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.Yamoussoukro,　　 Inspection before installation: Check the specification, size and quality of thick and thin accessories.　　The impeller of the submersible slurry pump may need to be disassembled for maintenance or repair during use. However, when we do not know the pump structure, we may make mistakes during disassembly. Let&#;s take a look at the correct disassembly of the impeller　　It is an auxiliary means for some on-site monitoring.

　　 there is also a simple method to measure the vibration frequency of the pump by vibration method. However when using one method, there may be some errors in the measurement results. When many equipment are used, there are other vibration sources that will affect the measurement results. Therefore, in fact, it is mainly　　 Pipeline booster pump: in fact, the pipeline booster pump is what we often call a booster pump. It is named according to the purpose of the pump. As the name suggests, any pump that can pressurize the liquid delivered in the pipeline can be called a pipeline booster pump. Not limited to one type of pump,FantinoCirculating hot water pipeline pump, such as centrifugal pump, pipeline　　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)Quality documents,　　Then there are new structures, such as thermohydrodynamic seals backup seals and asymmetric molded metal single wall bellows seals.　　 for screws that are too tight or rusted for a long time, or the nut can be gently knocked with a wooden hammer and then removed. This method can also be used in slurry pumps and other places.　　 Then reinstall the equipment on the engine and install the rubber hose.

　　 A vent pipe is installed at the bottom of the pump, so that when the pump is buried underground, water will be injected into the bottom of the slurry pump through the vent pipe, so that a sand water mixture will be formed at the bottom of the slurry pump,FantinoISG single stage vertical pipeline pump, so that the slurry pump can be started normally. The advantage of this approach is that even ifPackaging strategy,　　In fact, the pumps I am going to talk about here have a wide range of uses. Pumps are required for both civil and military purposes, as well as for advanced technologies,FantinoSubmersible sewage pump, especially in the mining, chemical, metallurgical and other industrial sectors. It is a widely used general mechanical equipment. Most pumps are corroded or severely corroded　　 Assembly of electric pump: assembly sequence of motor: stator assembly → lower guide bearing assembly → rotor assembly → thrust disc → left nut → thrust bearing assembly → base assembly → upper guide bearing seat assembly → skeleton oil seal → connecting seat. Adjust the studs so that the motor shaft extension meets the specified　　With the arrival of midsummer and the intensification of the contradiction between supply and demand of kerosene, the power supply across the country has been tense again, which has driven the hot sale of it and generators in the phase II market. According to relevant data, in the second half of the year, there is still a large gap after China&#;s power balance.Fantino, when the temperature rises to a certain value, the water begins to vaporize and change from liquid to gas. On the contrary, the pressure drops to　　Balance of.　　First, the reason for the motor body: the wrong connection will make the temperature rise rapidly when the equipment is used; In addition, there may be some phase to phase short circuits between stator windings, so when the situation is relatively minor, the motor is only in local places
