The double liquid grouting pump is mainly used for tunnel excavation and maintenance, road, bridge, dam, mine construction, and foundation treatment engineering of high-rise buildings, as well as various grouting construction projects. Its function is to inject easily solidified substances or mixtures into the cracks and cavities of rock layers or soil, in order to prevent leakage and strengthen the foundation. A single cylinder pump can be used for both single and double liquid injection, and the double cylinder pump is suitable for single and double liquid injection. Users can make reasonable choices based on the needs of the construction site. This series of products not only has a compact structure, stable performance, adjustable pressure and displacement, small volume, light weight, and easy disassembly and transportation, but also features reliable operation, high pumping pressure, more wear-resistant material cylinder, and long service life.

Working performance of hydraulic dual fluid grouting machine
This series of hydraulic grouting pumps is a professional grouting equipment that can achieve both single fluid grouting and dual fluid grouting.
Due to the use of full hydraulic pressure, it has a small volume and light weight, making it suitable for a wide range of construction.
3. Good adjustable performance: Within the design range, the pressure displacement of the pump can be adjusted arbitrarily. When the pressure exceeds the allowable pressure, the relief valve will automatically open, and the oil cylinder and working cylinder will stop working, playing a safety role.
After replacing the electric motor and air cooler of this series of grouting pumps with explosion-proof components, they can be used in flammable and explosive construction sites such as coal mines.
There is a seismic pressure gauge installed in the hydraulic system, which can accurately reflect the working status of the pump.
This series of hydraulic grouting pumps can also be used as clear water pumps, sewage pumps, and mud pumps.
Maintenance and precautions for hydraulic dual fluid grouting machine equipment:
1. The grouting pump should be placed in a horizontal position and fixed as much as possible to avoid twisting or folding of the oil pipe and suction pipe. The suction pipe should be shortened as much as possible, and its vertical distance should not exceed 1m.
Regularly inspect the fuel tank filter and oil circuit filter, clean them, and replace the hydraulic oil regularly. It is recommended to replace the hydraulic oil about once a month. Use No. 46 hydraulic oil in summer and No. 32 hydraulic oil in winter, with an oil volume of about 45Kg.
3. The workplace should have sufficient water sources for easy work.
4. Each hydraulic joint should be inspected regularly and not loosened.
Construction operators must have certain grouting experience to ensure smooth construction operations.
The electrical control box and motor should be kept clean and dry, and the integrity of the connecting wires should be checked regularly to avoid damage and leakage.
When moving the machine, do not have large bumps and do not knock on any parts of the machine at will.
