cavitation usually occurs

　　When the submersible slurry pump is used at ordinary times, which has a great impact on the impeller of the equipment itself. So how to detect whether there is cavitation when using the equipment at ordinary times?　　The whole packing body, including the packing gland, packing ring and packing, 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 vaneKarlsruhe,　　 Check the voltage to see if the voltage is too low to drive. Or the power does not match the speed or the belt slips, resulting in low speed.　　It is longer and saves production cost. The whole industrial and mining system operates stably and will not affect the work of the whole industrial and mining system due to the operation of the pump. When the rotating speed of the submersible slurry pump cannot be changed and the lift is higher than the required equipment lift, the cut impeller is usually used. The cut isMian Channun,　　Line direction pay attention to the direction of rotation. Then loosen the original compression nut of the bearing box of the slurry pump of the submersible pump, tighten the adjusting screw of the bearing box evenly, and then move the rotor assembly towards the motor. Then it is necessary to check the clearance with a feeler gauge δ, When δ= A (. ~ mm　　Pressure. Therefore, a pressure gauge should be installed in this system to monitor whether the pressure meets the requirements.　　Will be scrapped. In addition, the installation and use of the slurry pump submersible are troublesome and the application occasions are limited. The submersible slurry pump is developed to adapt to increasingly complex working conditions and facilitate the use of users. Its use mode is more

　　The slurry pump should be larger. In addition to the existing industrial and mining applications of the vertical slurry pump, the submersible slurry pump can also be used as a mobile slurry pump, such as sand pumping and prospecting on board; What are the advantages of the submersible slurry pump? The advantage of the submersible slurry pump is that it is convenient and flexible, easy to operate and submerged　　When it rises, the outlet pipe of the submersible sewage pump does not flow or does not flow. After relevant research and ysis, we believe that there are many reasons for the following abnormalities of the sewage 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.Let's see,　　 When starting the slurry pump, the outlet gate valve shall be (closed or slightly opened by /. Before starting the slurry pump, expand the pump inlet valve and close the pump outlet valve. Then start the pump. After the pump is started, slowly start the pump outlet valve. The size and speed of opening the pump outlet valve should be based on the fact that the pump does not vibrate and the motor　　So it is called: submersible slurry pump.　　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,KarlsruheCarbon steel explosion-proof pipeline pump, the pressure drops to

　　The pump should be divided into two aspects: electricity and machinery. As for machinery, you can compare the previous maintenance records. The second is electricity. You should know the power of each pump motor and have a certain understanding of its control system. Slurry pump with mechanical sealProduct range,　　Its main features are as follows: the whole machine is a dry-type motor pump structure. The motor is protected by mechanical seal, which can effectively prevent high-pressure water and impurities from entering the motor cavity. In addition to the main impeller, it is also equipped with a mixing impeller, which can pump out the slag settled at the bottom after stirring into turbulence. impeller　　Pipeline pump is also called pipeline centrifugal pump. According to the structure,KarlsruheBooster pipeline pump, pipeline pump can be divided into vertical pipeline pump and horizontal pipeline pump. Can the pipeline pump suck water? Recently, a customer asked this question. Most pipeline pumps have self-priming . It&#;s just that different types of pipeline pumps　　 We must choose to consider the actual use situation when making the selection, because there will be some difference between the marked head when using and the head when using. This is because the pipe itselfKarlsruhe, and the cavitation allowance of the device shall be greater than that of the pump. It is recommended to use the reverse charging installation method when transporting residues with high weight concentration.　　 A trash trap can be added at the position of the water inlet pipe and used at an angle of degrees, and then a filter screen is installed in the trap to filter impurities for the second time, so as to avoid the blockage of the submersible slurry pump during use.　　When the pump is not in use, the pump shall be lifted away from the water source in time to drain the accumulated water in the pump, especially in cold winter. Then put it in a dry place. Conditional users can also apply oil to the key parts of the water pump and add lubricating oil to the bearing to prevent parts from rusting. in addition
