First, the structure of stainless steel gear pump 1, stainless steel gear pump is a horizontal rotary pump, the main pump body, gear, bearing seat, safety valve, bearings and seals and other mechanical components. 2, The pump body and bearing seat are made of gray cast iron. The gear is made of high quality carbon steel. It can also be made of copper material or stainless steel according to the special needs of users. 3, The packing seat on the bearing seat plays the role of axial sealing. KCB-300 ~ 960-type pump with mechanical density device, the bearings using single row radial ball bearings. KCB-18.3 ~ 83.3-type pump with three oil-resistant rubber ring and the middle of a spacer ring composed of adjusting pressure on the cover of the two nuts to adjust the degree of sealing, bearings using copper-based powder oil bearing. In addition, stainless steel gear pumps can be filled with packing to good flexibility, high temperature and low temperature, chemical stability and self-lubricating flexible graphite as a filler. 4, stainless steel gear pump equipped with safety valve, when the pump or discharge pipe failure or mistakenly discharge valve is completely closed and produce high pressure and high pressure impact valve will automatically open, remove some or all of the high pressure liquid back to low pressure Cavity, which pump and pipe play a safety role. 5, with flexible coupling directly connected with the drive motor, and installed in a public cast iron chassis. Second, stainless steel gear pump (stainless steel pump) features 1, stainless steel gear pump structure is simple and compact, easy to use and maintain. 2, stainless steel gear pump with good self-absorption, so each time before opening the pump without filling the liquid. 3, stainless steel gear pump lubrication is delivered by the liquid automatically reached, so the daily work without additional lubrication.
