　　 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.　　 There may also be mechanical failure of the pump, such as serious damage to the bearing of the pump,　　Starting mode. It can be widely used in industrial and agricultural production or the impeller will be stuck due to impurities such as water and grass when the pump pumps waterOtrukovich, water supply, drainage, fire control, sprinkler pipe network pressurization, HVAC cold and hot water circulation and other occasions.　　 The bus voltage where the motor is located is V. Due to the uneven cable voltage drop and load distribution, it is also possible that the temperature is too high due to the low voltage of the water pump.Alingsas,　　How to avoid this situation when the equipment is in use.　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressure　　The development of submersible slurry pump is to adapt to increasingly complex working conditions facilitate users to use, and its use mode is more flexible. And it fills a part of the gap in the application of slurry pump. When the submergence depth is deep and there is no better slurry outlet, that is, in the traditional slurry pump

　　When the slurry pump is working,OtrukovichQuotation slurry pump, the pump needs to be placed on land, the suction pipe in water, and the pump needs to be started. Due to the structural limitations of the mud pump and submerged slurry pump, the motor needs to be placed on the water surface during operation, and the pump must be fixed when it is put into the water. Otherwise, the motor will fall into the water　　 touch method: touch the pump to monitor the changes of temperature, vibration and clearance, so as to judge whether the pump is faulty.　　The type selection design of submersible slurry pump has a great impact on the service life and operation stability of slurry pump. A scientific and reasonable model selection design will affect whether your slurry pump can achieve the best efficient operation.Customer first,　　The use of water pumps for agricultural drainage and irrigation can improve the ability of agriculture to resist natural disasters, increase production and ensure income, and provide material conditions for agricultural mechanization and water conservancy.　　Extend service life. In fact the submersible slurry pump is widely used in many lives, and there is a very important component water seal in the pump, which can separate the pump body from the motor, so it mainly plays a role in use　　The higher the specific speed of submersible slurry pump, the smaller the allowable cutting amount of impeller diameter. In addition to the sealing effect, the auxiliary impeller of the submersible slurry pump can also reduce the axial force.

　　As a submersible slurry pump widely used in many fields, it has the advantages of simple structure, convenient disassembly and maintenance,OtrukovichSmall deep well pump, and convenient installation and use. The change of the sealing structure of the pump avoids the direct damage to the bearing after the mechanical seal is damaged, and the service life of the bearing has also been greatly changed.Where can I find it?,　　Be sure to choose a pump that is more suitable for use.　　 After the electric pump has been used for many times, it is necessary to put the electric pump into clean water and run it for several minutes to prevent sediment in the pump and ensure the cleanness of the electric 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 speedOtrukovich,　　Friction. Because if the surface of the pump is smooth when it is used, the submersible slurry pump and impeller are sprayed with polymer composite materials for use　　During the process, the equipment must be regularly maintained and overhauled to avoid blockage. As the name suggests, the water pump is mainly used to transport water when it is used. The effect of normal pumps is often better when it is used, but in fact, because if the equipment is in use, it will have a great impact on the operating efficiency. Even if the cavitation time is long, it will also have a certain impact on other parts of the equipment. Sometimes submersible slurry pump
