Installation Points & Common Faults and Solutions Of Industrial Pump

  1.Installation points

The installation position of industrial pumps should meet the requirements of allowable suction vacuum,must be based on a level and stable, to ensure the rotational direction of the power machine is consistent with the pump.When the power machine using the shaft coupling,and the axis must along the same line,in case the generate vibrating and bearing lopsided wearing when the unit runs.If you using the tape driver,the axis should parallel to each other and the belt wheel should In the same position.If have more than one unit in one room,between the units, the units and the wall should have at least 800mm distance.The suction pipe of industrial pumps must be sealed;minimizing bends and valves;should be drained of air when you fill the water;the pipe should not accumulate the air when it runs;the suction pipe coupled with the pump inlet upward sloping slightly;Inlet should have a certain depth of submerging.The pump’s holes should be based on the size of the pump.

  2.Common Faults and Solutions

Different types of pumps, the malfunctions are not the same.

  (1).Insufficient flow

Causes:Most of the affect of insufficient flow, suction pipe and bottom valve leak;the inlet clogs;The water depth of bottom valve is not enough;Pump speed is too low;Excessive wear of sealing ring and impeller;Suction height exceeded and etc.

Solution: Check the suction pipe and foot valve;Block the leaking source;Clean the sludge or blockages of the inlet;the water depth of the bottom valve must be greater 1.5 times than the diameter of the inlet pipe and increase the depth;Check the supply voltage, increase the pump speed, replace the sealing ring and the impeller;Reduce pump’s installation location or replace the high lift pump.

  (2). Excessive power consumption

Causes:Pump speed is too high,the shaft is curving and the shaft of motor and the pump is misaligned or not parallel;choosing the inappropriate pump’s head;Pump suction Inhale sediment or obstruction;the ball bearing of motor is damaged.

Solution: Check the circuit voltage, reduce the pump speed,correct the shaft or adjusting the relative position of the pump and motor;choosing the right lift for the pump,clean the sands and blockages;replace the motor’s ball bearings.

  (3).Severe vibration or noise of pump’s body.

Causes:The installation is not firm or too high;Motor’s ball bearing is damaged;the shaft is curving and the shaft of motor and the pump is misaligned or not parallel.

Install the pumps with a right way or reduce the installation height;replace the motor’s ball bearings;Correct the crooked pump shaft or adjusting the relative position of the pump and motor.

  (4).The shaft or motor bearings are overheating;

Causes:Lack of lubrication or the bearing is ruptured and etc.

Solution:Filling oil or replace bearings.

  (5)The pump is no water.

Causes:The pump and suction pipe are not filled with water;The water level is below than the filter pipe;The suction pipe is ruptured.

Troubleshooting the issue of bottom valve,filled with water;reduce the installation height; Make the filter pipe under the dynamic water level or pump up the water till dynamic water level higher than the filter pipe.
