Analysis of the operation method and precautions of the double-cylinder double-liquid hydraulic grouting pump

How is the double-cylinder double-liquid hydraulic grouting pump grouting? Many customers do not know much about the operation method of the double-cylinder double-liquid hydraulic grouting pump. Zhenjiang Diancheng grouting pump manufacturer kindly reminds that the grouting construction personnel must be trained and qualified before they can safely operate the double-cylinder double-liquid hydraulic grouting pump without training. Do not operate the grouting pump arbitrarily. Below, a detailed analysis of the preparations for the grouting operation of the double-cylinder dual-liquid hydraulic grouting pump, the formal grouting operation method and the precautions for grouting operation are made in order to understand and use the grouting pump.

1. Preparation work before grouting operation of double-cylinder double-liquid hydraulic grouting pump

1. Check whether the power supply is normal.

2. Check the motor and gear oil pump, and make a few turns.

3. Turn on the pressure gauge switch and release the pressure regulating handwheel of the relief valve.

4. Put the suction tube into clean water for testing.

5. Check whether the steering direction of the motor and gear oil pump is correct.

6. Check whether the hydraulic reversing valve block can control the reciprocating motion of the oil cylinder.

7. Start the motor, adjust the system pressure to 1-2Mpa, and run it for about 5 minutes (the mixer discharge valve is fully opened at this time). If the operation is normal, close the valve on the mixer and adjust the oil pressure to the required level. the maximum pressure, and then stop the pump, ready to work.

2. Formal grouting operation method of double-cylinder double-liquid hydraulic grouting pump

1. Open the grouting valve of the mixer and pour water for 1 minute.

2. If everything is normal, put the two slurry suction pipes into the slurry tank quickly and carry out normal grouting operation.

3. After each grouting, if you do not continue grouting, you should immediately transfer the two suction pipes to the clear water tank to clean the residual slurry in the pump to prevent the slurry from solidifying over time and increase unnecessary trouble.

4. After the working cylinder and the inlet and exhaust valve bodies are cleaned, the suction pipe should be taken out of the water, continue to start the machine, drain the remaining slurry in the working cylinder and the inlet and exhaust valve bodies, and then cut off the power supply.

3. Precautions for grouting operation of double-cylinder double-liquid hydraulic grouting pump

1. The grouting pump should be placed in a horizontal position as fixed as possible to avoid twisting and folding of the oil pipe and the suction pipe. The suction pipe should be shortened as much as possible, and the vertical distance should not exceed one meter.

2. Regularly check and clean the oil tank filter and oil circuit filter, and replace the hydraulic oil regularly. It is recommended to replace the hydraulic oil about once a month. Use No. 68 hydraulic oil in summer and No. 46 hydraulic oil in winter, and change about 45 kg of hydraulic oil each time.

3. The workplace must have sufficient water sources to facilitate work.

4. All hydraulic joints should be checked regularly and must not be loosened.

5. Construction operators must have certain grouting experience to ensure smooth construction operations.
