The balance ring is also disassembled; Then remove the last stage impeller and the key back, and the middle section including the guide vane; in addition, remove the impellers, middle sections and guide vanes at other levels in the same way until the submerged slag slurry　　When the equipment is in use, the water delivered in the pump receives the friction with the surface of the pump impeller, so the pump needs to consume more energy to reduce the friction and resistance caused by the surface when it is rotating. Water will slowly overcome it as it flowssan diego ,　　 particle size (maximum and minimum) mm　　The purpose is to inject liquid higher than . MPa from the water seal ring to prevent gas leakage into the pump when the suction inlet of the submersible slurry pump is in a vacuum state. When the water pressure in the pump is higher than . MPa, the sealing fluid .-. MPa higher than the pressure in the pump can be injected to seal and reduce leakageAyutuxtepeque,　　 First of all, we need to choose equipment with formal certificates when making choices. We must avoid buying some obsolete or inferior products. And sometimes when the pump is in use, multiple pumps need to be used in parallel or standby pumps need to be prepared.　　 In addition, the noise method directly detects the noise of the equipment in the detection process, but this measurement will also be affected by the surrounding noise, so in fact, this measurement is not very accurate.　　.

　　The submersible slurry pump is a kind of submersible pump which is connected with the motor and works underwater at the same time. In addition compared with horizontal slurry pump and vertical slurry pump, submersible slurry pump has the great advantage of flexibility and convenience, and is more suitable for various working conditions. The important technical points of submersible slurry pump are its motor and　　(b) The maximum ambient air temperature varies with seasons,san diego Deep well pump, but does not exceed ℃.　　Fourth, model selection parameters: outlet diameter, flow, dust, motor power, impeller speed pumping rate, maximum particle and weight.ranking,san diego Vertical multistage centrifugal pipeline pump,　　 If the pump is equipped with a vacuum gauge or pressure gauge, close the cock connected with the submersible slurry pump before starting the motor, open it after the speed is normal and then gradually open the outlet sluice valve. If the flow is too large, if the flow is too small,Open the gate valve.　　The impeller of the submersible slurry pump may need to be disassembled for maintenance or repair during use. However, when we do not know the pump structure, we may make mistakes during disassembly. Let&#;s take a look at the correct disassembly of the impeller　　 First, screw down the bolts on the side bearing pressure cap, stuffing box body and bearing body; Then screw off the round nut on the shaft, and successively install the bearing inner race, bearing gland and retaining sleeve

　　After meters, the sealing of the equipment can not bear the water pressure at this depth.Finance Department,　　During normal operation, the temperature of the motor is very high, some even as high as ℃. In this case, it is easy to burn the motor and replace it with a new one. In fact, one motor burns out at this time. Don&#;t worry about replacing it. You must find out the cause of the motor&#;s heating, it should be started up once a week and run for - minutes to prevent the electric pump from being started due to corrosion.　　 Precautions for disassembly of submersible slurry pump Before disassembling the filter press, make sure that the liquid in the submersible slurry pump is completely discharged. If the rotor is disassembled, drain the lubricating oil in the rotor bearing housing. If the newly added oil is stored, it should continue to be used after maintenance. Do not dump it directlysan diego ,　　If the pump outputs more medium liquid, it will certainly do more work. If it sends less water, it will certainly do less work, 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　　Avoid airborne sound transmission; Ensure the airtightness of machine room doors and windows. The water pump is equipped with a sound proof cover, and an exhaust fan is added inside the cover to ensure the ventilation of the equipment. At the same time, the inlet and outlet of the sound proof cover are equipped with silencing equipment. A vibration isolation platform is installed at the bottom of the water pump for foundation vibration reduction to isolate the vibration generated during the operation of the water pump　　The vertical sand pumping pump is popular with a wide range of sand pumping pump users because it is easy to move. This equipment is made of high-tech endurance data. Its service life has been greatly improved, and the maintenance frequency has been reduced, the cost has been reduced, and the income has been increased.
