90D hydraulic wet spraying machine is a three-in-one equipment of machine, electricity and hydraulic, which is widely used in highway, railway, infrastructure, hillside and other projects. It uses the thrust of hydraulic pump to make the oil cylinder move alternately to feed the material, and then spray it to the sprayed surface after compressed air and accelerating coagulant at the nozzle. Its production capacity is 3-9m³/h, and the maximum system pressure is 22MPa. The equipment has stable performance, few wearing parts and low maintenance cost. It has high degree of automation, PLC centralized control and simple operation. The conveying volume can be adjusted as needed, and the amount of accelerating coagulant added can be adjusted steplessly. It is equipped with automatic lubrication system to extend the life of the equipment. In addition, the hydraulic spraying concrete machine is compact and has a wide range of applications. It has small pulsation of spraying, good continuity, large amount of spraying material, energy saving and environmental protection, which is the best choice for infrastructure construction in the new era.
