22kw Irrigation Centrifugal Water Pump
22kw Irrigation Centrifugal Water Pump complies fully to the European Standard BS EN733 / DIN24255 of performance and dimensions. They are used for pumping clean water or liquids similar to water, achieving wide application in plants, mines, city water supplies, air-conditioning coolers, firefighting system and irrigation.
Pumps of the same model have different performance levels basing on different diameter after impeller trimming. Overall the whole series, there are only four sizes of shaft and five of bearing housing. As long as their bearing housings are of the same size, different pumps can interchange chief parts such as shaft, shaft sleeve, shaft seal, impeller nut, etc.
22kw Irrigation Centrifugal Water Pump is also very easy to be installed and maintained. Back pull-out design, driven through flexible coupling, so that pump casing and motor can remain in position while other spare parts are removed.
1). Check direction of pump rotation, which should be clockwise viewing from the drive side.
2). Check alignment of the couplings both of pump and motor before using. Over-tolerance will damage flexible elements in a short time, and also cause over standard vibration as well as noise.
3). Check leakage of gland packing and tightness of gland cover; make them adequate to the job. If it is fitted with mechanical seal, make sure that the pump is operating with water inside; otherwise the dynamic and stationary rings would be worn out in dry operation
4). Check oil level, which should be kept in the specified range by oil gauge If it is grease, make sure that the bearings are filled with grease.
