High-pressure grouting pump pressure grouting method refers to the use of hydraulic overpressure to solidified slurry evenly injected into the filler stratum, the slurry to fill, infiltration and squeeze, etc., drive out the water between the particles and air filled after filling Position, after a certain period of time, the slurry will be the original loose soil cement into a whole, so that reinforced soil foundation to reduce post-construction settlement. First, the use of grouting pump GZB-40C high-pressure grouting pump for high-pressure rotary jet supporting equipment, mainly for high-pressure rotary jet to provide high-pressure grout. For new buildings, highways, high-speed railway, subway and other soft ground reinforcement and reinforcement for the perimeter of foundation pit, cofferdam dam and reservoir seepage control. Second, the characteristics of grouting pump GZB-40C high-pressure grouting pump is the original GZB-40A, GZB-40B based on the gradual improvement made. Compared with similar products, the bearing-type transmission can avoid the sudden accident of the pin-type transmission, and prolong the service life of the power end; the bold crankshaft ensures that crankshaft breakage will never happen; the structure of the hydraulic end is reasonable and the disassembly is convenient , Accessories durable. For a very mature and applicable high pressure mud pump. Third, the injection pump parameters plunger stroke: 100mm speed ratio: 1 = 7.2545 plunger stroke: 169 times suction tube diameter: 50mm discharge tube diameter: 16 ~ 25mm plunger diameter: 45,50,55 mm output flow rate: 96 , 99,110L / Min Rated pressure: 42,40,35 Mpa (with 90kw motor) 35,30,28 Mpa (with 75kw motor) 25,22,20 Mpa (with 55kw motor) Motor Type: YCT335-4C Motor maximum speed: 1340r / Min Dimensions: 3050 * 1800 * 1150mm Weight: 3000kg This article is provided by Tianjin Poly High Pressure Pump Co., Ltd.
