XA end suction pump

Techincal Help

PIPELINE CONNECTION
The water pipe should have its own supports in order to avoid all the weights depressing on the pump.
The pump line should be connected to the discharge nozzle by means of a flaring pipe with taper 1:7.
The average flowing velocity of water in the pipe is recommended not to exceed 2-3 m./s.
As for the suction pipe, the follows must be considered: the pipe must be as short as possible so as to reduce the resistance possible.The pipe must be bent according to prevailing regulation. It is not permitted to have too small bending curvature in order to avoid producing excessive losses.The connections of the pipes must be tight to prevent air from entering into the pipes.
When the pump position is higher than the water level, a foot valve should be installed at the bottom of the suction pipe or priming by a vacuum pump.
A gate valve and a non-return valve are installed between the discharge pipe and the pump. The inner diameters of the valves must not be smaller than the discharge pipe. The non-return valve is located on fro-side of the gate valve.
OPERATION
Inspecting the dates in the nameplate such as capacity, head, speed, and they must be accordance with the requirement.
The couplings shall be operating smoothly when rotating the pump by hands.
The starting task is to inspect whether the rotation direction of the motor corresponds to the requirement of the pump.
The valves, the pressure gauge on the discharge nozzle and the screwed plug on the vacuum gauge must be closed.
The pump shall is filled with liquid before starting. For pumps with a suction diameter equal to or less 300mm, the plug on the pump cover must be taken out and water is poured in through the plug hole on the top of the pump cover. For pumps with a suction diameter larger than 350mm, open the cock on the top of the pump cover and under the water indicator, and then start the vacuum pump. When the water level reaches the water indicator, clock the cock immediately.
Having done the procedure described above, start the motor and open the cock for a pressure gauge.
When the rated revolution of the pump is obtained and the pressure gauge shows a proper reading, open the cock for the vacuum gauge and the gate valve on the discharge pipeline gradually up to the required extent.
For stopping the pump, close the gate valve on the discharge pipe line gradually, close the cock for vacuum gauge, then stop the motor and close the cock for the pressure gauge.
Caution: when the ambient temperature is at 0℃ or below, the water remained in the pump must be drained off through the holes under the suction and discharge nozzles.
When the pump is to be out of use for a long time, it must be disassembled, cleaned and then packed for storage.
