The purpose of ZJB-3 single cylinder grouting pump:

1. In construction engineering, it is used for vertical and horizontal transportation of mortar and cement slurry.

2. In the metallurgical and steel sector, it is used for repairing blast furnaces and other equipment.

3. Used for grouting in national defense engineering, civil defense engineering, mining, and tunnel construction.

4. In the chemical industry, it is used to transport magnetic materials and other media in slurry form raw materials.

5. In farmland and water conservancy projects, it is used to reinforce dams. Sand well drilling is used to reinforce the wellbore, etc.

6. In railway construction, it is used for grouting reinforcement of bridges and culverts.

7. Used for conveying fly ash slurry in thermal power plants.

8. Pre stressing component engineering is used for injection and expansion of cement slurry.

9. In highway pavement maintenance, it is used for void grouting at the bottom of cement concrete pavement. ZJB-3 single cylinder grouting pump:

(1) Regular attention should be paid to the indication of the pressure gauge. If the indication of the pressure gauge or the safety device fails to function after exceeding the pressure, the cause should be identified, the fault cleared, and then restarted.

(2) Pay attention to whether the structure of the mortar pump and motor is normal. When any faults are found, stop immediately, open the slurry valve to reduce pressure, and troubleshoot.

(3) Regular attention should be paid to ensuring that the gland is tightly pressed against the packing to prevent any leakage. If there is still leakage during compression, the packing or piston should be replaced according to the specific situation.

(4) The mixed mortar should undergo consistency measurement before entering the pump.During the test, the consistency meter should be placed perpendicular to the surface of the mortar and easily lowered to allow for self weight sinking.

(5) After the shutdown of each shift, it is necessary to immediately pump clean water and clean the inside of the pump until it is completely cleaned, ensuring that the ball valve, discharge port, suction port, and discharge valve are clean and unobstructed.
