TurnhoutDouble suction slurry pumpWhat are the detection methods

　　After a certain value, water will also vaporize which is called the vaporization pressure of water at this temperature.　　 drainage and water injection with vacuum equipment: the self exhaust of centrifugal pump is the same as the negative pressure exhaust of vacuum pump,TurnhoutSubmersible slurry pump, so the water ring vacuum pump is used for exhaust to achieve the of water inlet.Turnhout,　　It is worth noting that the QW mobile type is generally used without a fixed position, so it is usually used temporarily without an electric control cabinet, and a special person is required to control the shutdown of the water pump.　　In addition, the sundries inside the pump body and impeller shall be cleaned. Then calibrate the pump shaft and motor shaft of the slurry pump to make them on the same horizontal line.Timimoun,　　It can also be used for cooling and lubrication. Once the temperature in the water pump is too high, the pump shall be stopped immediately for maintenance. Otherwise, the excessive temperature will not only affect the wear of small parts inside the equipment,TurnhoutSubmersible sewage pump, but also seriously affect the working efficiency of the equipment. So what is the reason for the high temperature of the equipment　　The submersible slurry pump and equipment can also choose to add some water inlet detection devices according to the actual use needs. The overheat monitoring devices are often used in a large amount in time, so　　After that, before starting again, and then start the pump.

　　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　　Operation maintenance and upkeep During the operation of the electric pump, always observe the current, voltmeter and water flow and strive to make the electric pump operate under the rated working condition.　　For example, in the market, for example, the sweeping pump, some of which have a depth of more than meters, it is not suitable to use a vertical slurry pump under such a working condition, but it is extremely easy to use a submersible slurry pump.Installation requirements,　　What is the solution to this situation?　　 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.　　Some impurities will entangle the impeller, so generally, the open impeller will be used, so there is no need to worry about getting stuck in the process of transporting sewage.

　　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,　　 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　　 The reasons for excessive power loss are as follows: the running speed of the screw rod is too high.　　 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, so that the slurry pump can be started normally. The advantage of this approach is that even ifTurnhout,　　It will generate heat, but when it is serious, it will directly burn out the insulation; There may also be some faults in the ventilation system. At this time, it is necessary to check whether the fan of the submersible slurry pump is damaged or rotating　　About %),TurnhoutAh slurry pump, and motor power p=i × U indicates that high power and current will increase.　　Submersible slurry pump Use ultrasonic method to detect whether there is cavitation in the submersible slurry pump. This method is often convenient for re detection. Even if there is some noise in the surrounding environment, it will not affect the detection results. Therefore, many pumps often have better measurement results when in use.
