[Asia Pump Network News] KCB pump consists of pump body, gear, front and rear pump cover, safety valve, bearings and seals and other components, zero. Now to introduce the structural characteristics of KCB-type gasoline pump what? Gasoline pump KCB-type gasoline pump structural features 1, the pump body, before and after the cover and other parts of gray cast iron, gear made of high-quality carbon steel. 2, safety valve 2CY series gear lubrication pump itself without safety valve, users need to install their own safety valve in the pipeline system. KCB, 2CY series pump installed in the rear pump cover or pump body safety valve, gear pump pump or discharge pipe failure or the discharge valve is completely closed to produce high pressure and high pressure impact safety valve will automatically open, remove Part or all of the high-pressure liquid back to the suction chamber, which pump and pipe play a safety role. 3, bearing 2CY series pumps all use DU bearings; tin bronze bearings can be used according to user requirements. & 0818.3-83.3,2CY1.1 gear pump with DU bearings. 4, shaft seal This series of gasoline pump shaft seal has a skeleton oil seal, mechanical seal and packing seal three structures. a. Skeletal Oil Seal: Skeletal oil seal is characterized by maintenance, easy replacement, low cost, but shorter life expectancy. NBR frame oil seal is suitable for 1001: the following working environment; FKM oil seal is suitable for the following 200 ℃ working environment. b. Mechanical seal: mechanical seal is characterized by reliable sealing, long life, high cost. The base of the mechanical seal is made of stainless steel. The different media of the dynamic and static rings are respectively made of YG8 cemented carbide or YG8-graphite, and the working temperature is below 200 ℃. c. packing seal: packing seal is only used for high temperature pump, which is characterized by high temperature, a small amount of leakage. The use of the process should be adjusted according to the leakage often, the use of temperature below 250 ℃. 5, into and out of the port Type 2CY series of gasoline pump inlet and outlet ports and the diameter corresponding to the British pipe thread (G), directly produced in the pump body. KCB18.3-200,2CY1.1-12 gear pump with pipe thread mouth waist-shaped flange; the remaining pump is not equipped with flange. 6, pump and motor with flexible coupling connection, and installed in the public chassis.
