KCB-300 stainless steel gear pump is a gear pump, specifically a kind of acid-resistant, wear-resistant gear pump. According to the design proposal provided by the utility model, the driving shaft and the driven shaft are mounted on the housing, the gear is mounted on a section of the driving shaft located in the housing, the gear engaged with the gear is arranged on the driven shaft to form a pair of gear pairs, The shell is provided with an inlet and an outlet for materials. The utility model is characterized in that a ceramic plate is arranged on the inner wall of the cavity for accommodating the gear pair in the shell. The device by changing the gear pump structure, to improve the gear pump acid and wear resistance. KCB stainless steel gear pump gears are common spur, helical, herringbone, helical teeth, tooth profile are mainly involute and arc type. Usually small gear pump to use more involute spur gear, high temperature gear pump often use variable gear, conveying high viscosity, high pressure melt polymer melt more use of involute helical gears. Gear and shaft made of one, its rigidity and reliability is higher than gear and shaft separately manufactured gear pump. Foreign low-pressure gear pump gear is often used square structure, that gear tooth width equal to the addendum circle diameter. The high-pressure occasions used in high-viscosity gear pump gear tooth width less than its tip diameter, which is to reduce the gear radial compression area, reduce gear, bearing load. KCB-300 stainless steel gear pump It is mainly used in small flow, high lift water system, such as drinking water supply system, pressure boiler water supply system, high purity water purification system and pharmaceutical, food, fine chemicals, papermaking and other industries, washing, spraying Other processes. KCB-300 stainless steel gear pump is a new type of liquid conveying machinery, which has the advantages of simple structure, safe and reliable operation, convenient use and maintenance, continuous and uniform liquid discharge and stable pressure.
