        Instructions for use (i) the HW mixed-flow pump is composed of main parts such as pump body, pump cover, impeller, pump shaft and bearing body. (Ii) The pump cover is a part of the pump connected to the inlet pipe, with a specified axial end gap between the end surface and the impeller (maintaining the specified axial clearance after eliminating the axial activity gap of the bearing). The gap is too small to produce friction, too large will lead to the pump pressure water reflux, so that the pump efficiency is reduced, through the increase or decrease adjustment paper pad to meet the required requirements of the gap. Extended search: Water ring Vacuum Pump (iii) The sealing device is composed of a filler letter, a water seal letter, a filler cover and a lead powder (or oil immersion) asbestos root. Its role is: 1, in the tea to prevent air inhalation pump, play a sealing role. 2. When pumping, prevent water from flowing out of the pump too much along the shaft. (Iv) Shaft application to protect the shaft does not make it directly friction with the filler, if long-term use found that the bushing wear too much, can change the bushing. (V) The two supports of the pump shaft are bearings in the bearing body, and the bearing has an appropriate amount of grease in its body to lubricate the bearings. (Vi) The baffle on the shaft prevents water from flowing into the bearing body along the pump, thus protecting the bearing and extending its service life.
