XiaguanVertical multistage centrifugal pipeline pumpWhat are the selection criteria for

　　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,XiaguanVertical heavy-duty slurry pump,　　Causes: there is air or gas accumulation in the water inlet pipe of the pump or the bottom valve is not closed tightly, the water supply is not satisfied, the packing of the vacuum pump leaks seriously,XiaguanUsed pipeline pump, and the gate valve or flap valve is not closed tightly.Xiaguan,　　QW (WQ) submersible non blocking sewage pump shall be carefully inspected before operation? Whether the cable is damaged, whether the fastener is loose or dropped, and whether the pump is deformed or damaged during transportation, storage and equipment.　　 Impeller protection in order to ensure the operation of the submersible slurry pump, it is necessary to timely adjust the clearance between the impeller and the front guard plate. When adjusting the impeller clearance, first stop the pump loosen the bolts pressing the bearing box, make the bearing components move forward,　　Auxiliary mixing or spraying device shall be equipped for easier operation. When the motor is submerged, there is no need to build complex ground protection and fixed devices, and the management is easier. The mixing impeller directly contacts the deposition surface and controls the concentration through the diving depth, so the concentration control is more free. Equipment directly submerged　　 strip the outer layer of the cable to expose the copper wire for to mm, gradually thin the rubber near the wire core, grind it to the oxide layer on the wire core, wipe the wire core with alcohol (or hydrochloric acid), wrap the insulation layer and sheath layer, and dry it naturally.　　It, generator and market formed at the beginning of construction have gradually formed a certain scale after more than ten years of rapid development. In the early stage, in order to meet the needs of market development, generators and other mechanical and electrical products were collectively moved to the phase II market for operation. With a good business environment, water pumps and generators

　　In the application of pumps, the first thing we think of is water. Whether it is drinking water or coefficient water,XiaguanSingle stage slurry pump, even the polluted water in cities needs to be purified. All these require its equipment to provide services for us. Without pumps, our basic survival is a problem.　　Try to select the pump with appropriate lift.　　The hardened mud layer collapses after softening, avoiding the phenomenon of burying the pump during use.query,　　If there are sundries blocked, the pump will not be filled with water. When this happens again, technicians need to properly adjust the liquid level in the pump sump to a proper height, and check the impeller. In case of damage or aging, it needs to be replaced in time, we can check whether these reasons are the above. This is also a reminder that we need to maintain the pump during normal use. latent　　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, when the temperature rises to a certain value, the water begins to vaporize and change from liquid to gas. On the contrary, at a certain temperature, the pressure drops to

　　 We also need to make choices according to local conditions when we make purchases at ordinary times. For example, the head of the centrifugal pump itself is relatively high, but its water output is not very large when it is used, so it is effective when it is used in many mountainous areasScheme customization,　　The whole packing body, including the packing gland, needs to be disassembled; Submersible slurry pump Disassemble the o-seal ring, shaft sleeve, balance disc and key on the shaft in turn, and then the discharge section includes the last stage guide vane　　 the insulation resistance between the shaking cable and the submersible slurry pump shall not be less than megohm.　　The water slurry pump is a widely used equipment. Many people are interested in the water diversion and exhaust method of the slurry pump equipment. Now let&#;s talk about the water diversion and exhaust method of the submersible slurry pump: the submersible slurry pump needs to pump out the water to form a vacuum, and then supply water,Xiaguan,　　Therefore, the correct selection of shaft seal can ensure the safe and stable operation of slurry pump.　　Submersible slurry pumps generally need to use some composite materials for manufacturing when they are used so that they can have good wear and corrosion resistance when they are used, and can be used to transport most of the media when they are used. Phreatic slurry　　 When stopping the operation of the submersible slurry pump, close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline, and After that, cut off the power supply of the motor. If the temperature of the environment is low, open the square plug at the lower part of the pump body to remove the remaining water to avoid frost cracking. During operation, the maximum temperature of the bearing shall not exceed ℃, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing body
