Sign in perhaps register 。

and the external tap water shall be connected for cooling during operation the hot water pump must be used, otherwise the motor will not be burned due to too high medium temperature.　　 Prepare tools and materials: a set of metric box / open-end wrench, magnetic dial indicator, outside micrometer,ZatezVertical centrifugal slurry pump, caliper, feeler gauge, square ruler, copper bar, screwdriver with handle, hammer, V-shaped irons of the same specification, clean kerosene, oil basin, cotton yarn etc.Zatez,　　 The fire control cabinet has fault alarm . When a single fire pump is working, it is not easy to be found in time in case of insufficient water source, power circuit failure, etc., resulting in damage to the fire pump. Using the fire control cabinet, the alarm of the control cabinet can remind each　　 Prepare tools and materials: a set of metric box / open-end wrench, bearing puller (commonly known as triangle puller), magnetic dial indicator, outside micrometer, caliper, feeler gauge, square ruler, copper bar, screwdriver with handle, hammer, V-shaped irons of the same specification, clean kerosene, oil basin,ZatezVertical multistage centrifugal pipeline pump, cotton yarn, etc.Villamontes,　　 The submersible slurry pump needs to be inspected after reassembly. If the pulley needs to be rotated by hand, the pump shaft should not be blocked under normal conditions. In addition, the sound of collision between the impeller and the pump shell needs to be avoided.　　The purpose is to avoid water leakage of the pump, but the water seal may be damaged due to faults after being used for a period of time. Let&#;s learn how to replace the water seal.　　During adjustment, firstly loosen the support cover, then compress the nut, and then loosen the bearing seat. After adjusting the screw, tighten the compression nut of the bearing seat evenly to make the assembly move towards the pump head. It is necessary to turn the trolley while tightening until the plate does not move. Rotate according to the pump operation

　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition, 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.　　The ability of dirt passing through makes it safer to use.　　 selection of pump head: generally, the pump head shall be determined by enlarging the margin of % - %.Recommendation and consultation,　　When in use, it can drive the impeller to rotate so as to drive it to flow.　　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　　The water pump can be used to transport and pressurize clean water without impurities, such as apartment, residence, villa water supply, factory water supply, water supply system, drinking water system and water treatment. In short, there are many uses.

　　Water flow into the bearing damages the bearing.Manufacturing cost,　　Second, the power used is not matched, so the motor temperature will be too high after long-term overload operation; In addition, frequent startup during use will also lead to fever, so I　　Pipeline pump, belonging to the category of centrifugal pump, is a single-stage centrifugal pump with standing structure. Because the layout design of its water pump inlet and outlet is relatively special, they are all located on the same straight line,ZatezVortex pump and pipeline pump, and their inlet and outlet diameters are the same,　　If the pump outputs more medium liquid, it will certainly do more work. If it sends less water, and the current will be correspondingly reduced. Pump power (kw) = head (m) × Flow (m/s) × The gravity of the fluid (kg/m for water) divided by (power conversion factor) divided by the efficiency of the pump (about　　The above is about how to replace the water seal of Boshan submersible slurry pump. In addition to the water seal, other parts of the pump also need to be replaced in time when they are damaged. Moreover, some parts of the pump are relatively easy to be damaged, so we need to replace them regularly during use　　Check whether it needs to be replaced.　　Stop, then tighten the bearing seat, and fix the axial position of the rotor. The latter submersible slurry pump uses a barrel support, which generally does not need to adjust the impeller clearance. Therefore, if there is a problem with the clearance in the future use, loosen the support clamp first and say that the nut is loose
