So how to detect whether there is cavitation when using the equipment at ordinary times?Information recommendation,　　Slurry pump Inappropriate model is selected when selecting the pump. In actual use, when the load conditions do not match the model of the slurry pump, for example, the pump lift used is too high or too low, which will lead to overload, so we are selecting the pump　　It is worth noting that the vertical pipeline pump can work like the self-priming pump after it is equipped with a siphon device. However, due to the existence of the self-priming pump, few people will install this device for the vertical pipeline pump.　　If the submersible slurry pump cannot be installed and operated, the blank operation point can be supplemented.Chatak,ChatakSubmersible pump can pump sewage,　　 One frequency converter with one slurry pump is adopted for installation. The specific transformation method is as follows: close the return valve, adopt the water level closed-loop control mode, install the liquid level sensor on the inner wall of the tank by the manufacturer of the slurry pump and use the PID adjustment of the frequency converter. When　　Generally, the diving depth of the submersible slurry pump is not more than meters, and the operation is reliable. Why not more than meters? This is the crucial technical point of the submersible slurry pump, not because the slurry pump has a problem, but because　　When using the submersible slurry pump, we should do a good job in all aspects of commissioning and precautions. We also need to do a good job in protecting the equipment parts and some parts of the motor. Only in this way can we avoid the impact of water and other impurities entering the motor

　　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　　 It may be that the motor power of the water pump is too large, the working current is too large, and the heat generation is too large, resulting in the high temperature of the vacuum pump.Bnei Brak ,　　The resistance loss in the lifting pipe and the resistance loss of the water delivery pipe after the outlet of the pump base.　　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.Sangmelima,　　 Another possibility is that the gas is sucked in when the pump is in use.　　Submersible slurry pump In addition, it must be used continuously during transportation. If there is an interval in the middle it must be avoided that the interval is relatively long, so as to avoid the solidification of slurry in the pump when the operation is stopped.　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition,Bnei Brak Vertical slurry pump,Bnei Brak Ah slurry pump, 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.

Only after the first stage pump is started,Bnei Brak Vortex pump and pipeline pump, the submersible slurry pump can open the outlet valve of the last stage pump (the opening size is based on the motor current of the first stage pump as the rated power　　(b) The maximum ambient air temperature varies with seasons, but does not exceed ℃.　　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,Fair price,　　Only in this way can its service life be extended to a large extent.　　It will burn out. If there is a heating problem in use, you can refer to the following reasons.　　The above introduction is about the cause ysis of the overload of the slurry pump. When we find these conditions when using the pump, 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

　　 The pump body (can not) bear the pressure from the outlet pipeline system. The standby pump in the warehouse should rotate (/ times a week to make the shaft bear the load and external vibration evenly. The belt CR drive is that the motor is on the (right) side of the pump from the inlet of the pump.technological innovation,　　 The submersible slurry pump usually relies on water cooling to dissipate heat. If the motor leaks out of the water without water cooling, the motor temperature will rise, so it is easy to burn out the motor.　　If you want to know how the slurry pump is classified, and a device that converts the electric energy into the kinetic energy and potential energy of the medium. and　　In recent years, the demand for submersible slurry pumps has increased greatly. In many fields, submersible slurry pumps have replaced vertical slurry pumps. What are the differences between the two? Let&#;s yze.Bnei Brak ,　　The direction of the differential pressure force is opposite, which can offset part of the axial force and prolong the service life of the bearing.　　Under the action of auxiliary devices, it can transport the slurry, and because the sealing device itself is special, it can also ensure the internal and external balance of the submersible slurry pump during transportation, so that the pressure at both ends of the equipment can be balanced during normal use　　The vertical sand pump is generally a submersible slurry pump. Its main application method is that the motor and water pump can pump up the materials that need to be escorted when they are put into underwater mining.

　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand, although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum. The main reason is that the above-mentioned use is convenient and flexible; In addition the application market of submersible slurry pump is also better than that of vertical pump　　This phenomenon shows that the failure of the pump is not only a material problem, but also reminds the pump designers and producers that in addition to good working conditions, the pump should also have good corrosion resistance, high reliability and long service life.
