The high-pressure grouting machine for mining should be fixed in a flat position as much as possible to prevent the oil and slurry pipes from being distorted or discounted. The slurry pipes should be minimized as much as possible, and their safe distance should not exceed one meter. Regularly maintain the fuel tank mesh and fuel pipe filter mesh, clean them, and replace the hydraulic oil on time. Generally, the hydraulic oil should be replaced up and down every month. In summer, use No. 68 hydraulic oil, and in winter, use No. 46 hydraulic oil. Change the hydraulic oil by 45kg each time.
The working position of the high-pressure grouting machine for mining should have sufficient water resources for easy operation. Each hydraulic joint should be regularly maintained and not loosened. The operators must have certain grouting work experience to ensure the smooth progress of successful construction and quality assurance. Electrical control cabinets and motors should be kept clean and dry, and transmission lines should be regularly checked for damage and leakage.
If the high-pressure grouting machine for mining is no longer in use in the near future, the oil circuit and cylinder should be dismantled, cleaned up, brushed with rust proof water or vegetable oil, and then installed for proper storage. Ensure that there is no slurry inside to avoid being blocked and unable to work in the next use.
