Friction. Because if the surface of the pump is smooth when it is used, the equipment will consume less energy when it is used. Generally, the submersible slurry pump and impeller are sprayed with polymer composite materials for use　　 When the power supply voltage is too low, the pump will be overloaded, because the pump is also widely used in many rural watering. In this case, it may be lower than the rated voltage, so the current in the stator winding will also bePasabad,　　The self-priming pump is a self-priming centrifugal pump. It has the advantages of compact structure, convenient operation, stable operation, high efficiency, long service life, and strong self-priming capacity. There is no need to install the bottom valve in the pipeline. Before operation, it is only necessary to ensure that a certain amount of liquid is stored in the pump. Different liquids can　　 After each use of the equipment, high-pressure water should be used to wash the pump and pipes. The washing can be stopped until the water has no impurities.Levittown, 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 if　　Friction. Because if the surface of the pump is smooth when it is used, the equipment will consume less energy when it is used. Generally, the tape shall be stretched twice, and then the three layers shall be folded in half with PVC tape to ensure that the winding part is not less than mm, and the positions of the three joints shall be staggered for a certain distance in order to prevent short circuit.

　　 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.　　 When the slurry pump operates, it rotates at a high speed, and the components of the slurry pump have a heavy weight. Therefore, once it reverses the force will directly push the impeller to the outside, and the impeller collides with the sheath and guard plate. If the speed is high, the force ratio is low　　Normal operation. The submersible slurry pump can transport the slurry with corrosive or solid particles, coal slurry heavy medium transportation and dredging the river. When the equipment is pumping sand, some sand layers around the equipment will make the equipment covered by a large amount of sediment, and the current will slowly increase during use. Well,PasabadDeep well pump, we should chooseconsumption,　　The slurry pump of underground pump can also work normally.　　 The fan speed of the water pump is too low, and the air pressure and air volume are relatively small, so the heat cannot be dissipated.　　 Impeller protection in order to ensure the operation of the submersible slurry pump, it is necessary to timely adjust the clearance between the impeller and the front guard plate. When adjusting the impeller clearance, first stop the pump, loosen the adjusting nuts, make the bearing components move forward, and roll the shaft by hand to press the

　　 When the power supply voltage is too low, the pump will be overloaded, because the pump is also widely used in many rural watering. In this case it may be lower than the rated voltage,PasabadSplit vertical pipeline pump, so the current in the stator winding will also beInstallation works,　　The solution to the excessive temperature of the water pump: when selecting the motor, it is necessary to select one that matches its power and speed. In addition, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, but pay attention to adjusting the vacuum pump　　 check the cable and replace it if it is broken or broken to avoid leakage.　　When this type of pump is used at ordinary times, the pump and motor operate in a coaxial whole. When it runs, the motor shaft will drive the impeller of the pump to rotate, and then at this time, the rotating force can be brought to the medium, so thatPasabad,　　Friction. Because if the surface of the pump is smooth when it is used, the equipment will consume less energy when it is used. Generally the submersible slurry pump and impeller are sprayed with polymer composite materials for use　　 Dust and oil stains on the motor reduce the heat dissipation capacity of the equipment and cause the equipment temperature to rise.　　 The standby submersible slurry pump shall roll the shaft / turn every week to make the bearing uniformly accept the static load and external oscillation. The building structure in the water pump room shall be reconstructed. Sound absorbing and isolating plates shall be installed around the wall and on the top of the machine room and fixed with light steel keel; The connecting holes between the machine room and other rooms are tightly blocked,
