  Limited. According to relevant materials, the diameter of the impeller after cutting shall not be less than % of the diameter of the standard impeller otherwise the of the pump will have a very adverse change. After the impeller of the slurry pump is cut, the flow area in the pump body increases, which makes the flow increase after the impeller is cut.   the submersible slag pump is often used to transport pulp containing solid particles, so the wear resistance of the pipeline should also be considered.St. John,   Gradually disassemble the outlet pipe, gate valve and elbow with installation tools, and tighten the next section of water pipe with pipe clamping plate. In this way, disassemble the pump section by section and lift the pump out of the well. (if it is found that there is a jam during the lifting and removal process, it cannot be lifted by force, and the customer service points shall be moved up and down, left and right for safe lifting and removal)  The use of water pumps is related to all aspects of our life. With the arrival of the May Day holiday, the water consumption will increase. Therefore, it is necessary for us to choose a suitable water pump.Klagenfurt,  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  Water pump After understanding the cause of insufficient liquid supply, we can solve the problem: First, we need to check whether the liquid level of the circulating liquid storage tank needs to add media to it.  The solution to the excessive temperature of the water pump: when selecting the motor, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, the slurry pump has high operation efficiency and low loss.  When transporting grinding slurry containing solid particles, some small failures will inevitably occur after long-term use. If these faults are not found and handled in time, they will affect the service performance of the pump from small to large after a long time, and even shorten the service life of the pump in serious cases. To avoid  Water pump After understanding the cause of insufficient liquid supply, we can solve the problem: First,  The Tao part also consumes part of it.  The structure of the submersible slurry pump will be more intuitive. First, the equipment will use centrifugal force to drive the liquid from the impeller to the outer edge and obtain energy, and then leave the edge of the impeller at a higher speed  Do not exceed the rated current.

  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,Potential development,  Ordinary vertical motor can be used without waterproof, while the motor shaft and pump shaft of submersible slurry pump are coaxial,St. JohnSewage pump diving, so the motor must be waterproof and sealed, and the motor and pump can be immersed in liquid at the same time; The vertical slurry pump is an early product, and the submersible slurry pump is a newly developed product according to the market demand  Correct the bent main shaft and adjust the position of the motor and the water pump to make them parallel.  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, When δ= A (. ~ mmSt. John and then move the rotor assembly towards the motor. Then it is necessary to check the clearance with a feeler gauge δ,St. JohnSubmersible sewage pump,  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.  The above four methods can be used to detect whether the submersible slurry pump has cavitation, 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   If the power cord is not well contacted, it will also lead to the burning of the motor.
