High pressure pump is the equipment that provides high pressure power for high pressure rotary jet mud, which is used for strengthening and strengthening the foundation of buildings, highways, etc. It can also be used for high pressure water jet auxiliary rock breaking and coal dropping, underground hydraulic support for liquid supply, anchoring water expansion metal anchor to pump high pressure water, dredging and cleaning of large underground pipelines. The low pressure pump is a centrifugal pump with a rated head of 1-100m. The easy difference between high pressure pump and low pressure pump is the level of pressure, but the difference behind this must be more than this, we must know how to accurately distinguish it in order to use it in the actual work. The following is the structure after comparing the high pressure pump and the low pressure pump, from which it is not difficult to find the difference?
First from the appearance of the structure, the high pressure pump and the low pressure pump volume and the material used are different, the high pressure pump pump body is obviously much larger, and its material requirements are relatively high, to have the basic ability to withstand greater pressure and torque. The support methods used by the two pumps are also different, the high pressure pump is more supported by the center, and the low pressure pump is mainly supported by the pump foot.
If you look carefully, it is found that the type of bearings in the high pressure pump and the low pressure pump are different, because the power of the high pressure pump is relatively large, so the sliding bearing can meet the needs of the low pressure pump, and the rolling bearing can be. From the point of view of its internal performance, the specific speed and head of the pump have different performances.
