News Detail
Earlier Concrete shotcrete machine appearred as a pump products , it is the working chamber by means of periodic changes in volume to achieve the purpose of transmission fluid. Its main role is in the process of drilling mud into the hole with the drill bit, play a bit cool, clean drilling, fixing the wall, drive drilling and cuttings back to the role of the ground after drilling.

4.The commissioning of the l00h, pump load, torque, pressure, speed, etc. should be 50% to 75% of the rated value;
5. Commissioning period, bearings, guides packing boxes, transmission gear, etc. The temperature must not exceed 75 ℃, the oil must flow, oil pressure should be 0.1 ~ 0.4 (MPa) between;
6. The new pump is running 50h, lubricating oil must be replaced after each operation 700h, change the oil once again;
