GZB-40C a high-pressure injection pump, injection pump uses GZB-40C-pressure injection pump for high pressure jet grouting equipment, primarily to provide high-pressure water spray high pressure slurry spin. For the new building, highway, railway, underground railways and other soft ground reinforcement, seepage treatment for around foundation, cofferdam and hydropower dams. Second, the injection pump characteristics GZB-40C-pressure injection pump at GZB-40A is based on the original, GZB-40B on the gradual improvements made. Compared with similar products, which can avoid needle bearing Transmission Transmission sudden accidents, power end to extend the working life; its bold crankshaft guaranteed never be broken crankshaft happen; reasonable hydraulic end structure, easy disassembly accessories and durable. Suitable for a very mature high-pressure mud pumps. Third, the injection pump parameters plunger stroke: 100mm Ratio: 1 = 7.2545 plunger stroke frequency: 169 times the suction pipe diameter: 50mm exhaust pipe diameter: 16 ~ 25mm piston diameter: 45,50,55mm output flow: 96, 99,110L / Min rated pressure: 42,40,35Mpa (with 90kw motor) 35,30,28Mpa (with 75kw motor) 25,22,20Mpa (with 55kw motor) Motor type: YCT335-4C motor maximum speed: 1340r / Min Dimensions: 3050 * 1800 * 1150mm Machine weight: 3000kg crankshaft diameter 133mm, not easy to wear, damage; tile type transmission, not damaged, does not affect the field of engineering process; forging ensuring the life of the pump head.
