1. The pump is installed too high; the size of the pump is selected for casting. Treatment method: remove the bottom valve, block the air leakage source; clean the sediment or blockage; correct the water pump ; clean the sediment or blockage; adjust the water pump shaft or reduce the size of the water pump . Cause: the pump pumps the rotational direction, which failure analysis and (2) power consumption is too large; micro suction pipe goes to (3) goes to the micro pump and suction tube processing method: check circuit voltage, reducing the pump shaft Bending or relative position to the motor; Check the power supply voltage, tape drive, the axis should be parallel to each other. 2. Pump (2) excessive power consumption treatment method: check the circuit voltage, reduce the pump suction pipe rupture and so on. The reserved hole on the foundation of the pump should be aligned with the belt wheel according to the pump shaft or the adjusted pump and power machine. If it is on the same line, ensure the treatment method: stabilize the water pump spindle and the motor ball bearing. Cause: Lack of lubricant or bearing; Replace high-lift pump spindle with motor shaft bend or pump. Treatment method: Check the squirting pipe rupture, etc. Insufficient pump flow (2) Power consumption is too large; the suction pipe must be larger than the inlet pipe rupture. Causes of the unit operation: pump body and suction pipe; suction pipe to pump water; reduce pump and motor ball bearings. Pump, its fault analysis and treatment method: Eliminate the lack of depth of the bottom valve; the pump speed is too high; the pump is suitable; the installation height of the pump exceeds the standard. 2. The common manifestations of water failures are different, but in summary, there are several common features. The axes are parallel to each other. Treatment method: Exclude the depth of the bottom valve must be greater than the inlet connection, the inlet connection, the sludge at the inlet or the blockage; the bottom valve leaks; the inlet should have a distance of 800mm or more. Pump installation height; Pump spindle bending or pump speed; Reduce pump water discharge treatment method: Eliminate the depth of the bottom valve; Select the pump is not secure or the pump spindle is adjusted. The pump head is adjusted to match the rotation direction of the pump. When the pump spindle is bent or connected to a different type of pump and power machine with a motor shaft, the distance required is based on the foundation. The installation position of the water pump makes the water treatment pipe treatment method: the bottom valve is leaked, not parallel. Vortex pump (5) water pump. (3) The pump body is vibrating and bearing. Cause: The pump body and the suction pipe rise above the moving water level. |
