Single-stage centrifugal pumps in China's industrial, agricultural, construction, fire, chemical, petroleum and other fields of drainage has a very important role, it was born to help workers in such industries to be better, more Quick start working. With the rapid economic development in our country, the development of these industries is in the best period of development. The use of single-stage centrifugal pumps is also facing more opportunities. So single-stage centrifugal pump selection considerations what? Single-stage centrifugal pump selection precautions 1, check the single-stage centrifugal pump with or without reliable grounding device and safety protection device, so as not to affect the safe use of sewage pump. 2, according to the single-stage centrifugal pump price, quality, operating costs and installation, easy maintenance and other factors to consider the selection of a suitable pump. 3, stainless steel sleeve: shaft sealing position is relatively easy to be corroded, straight-type pump shaft once corroded, easy to cause mechanical seal failure. STG pump fitted here with stainless steel bushings to prevent corrosion occurred, improve the shaft life, reduce operating and maintenance costs. 4, bearings: pump with the motor, Y [Y2] 280 below the shaft end bearings [including Y180 the following fan-side bearings] with closed bearings, normal use, maintenance-free motor bearings. 5, mechanical seal: mechanical seal base generally use rubber bellows structure, the traditional mechanical seal on the shaft seal from the O-ring seal to the two pieces of rubber seal, sealing effect in the water medium to improve the sealing effect. Through the above introduction, we generally know what type of single-stage centrifugal pump roughly what. However, in the actual work of a single-stage centrifugal pump, different workplaces, different work intensity, different workers suitable single-stage centrifugal pump is different, which requires users to purchase single-stage centrifugal pump to do more practical investigation and preparation . This can play a single-stage centrifugal pump maximum efficiency, but also to ensure the smooth progress.
