　　When discussing cement slurry consolidation engineering, it is almost always mentionedPneumatic grouting pump for coal minesTo strengthenZBQ27/1.5 Pneumatic grouting pump for coal minesIn terms of usage status, we need to actively recommend and establish a good service mechanism. Hongyi people are actively striving for market position and sincerely hope to receive your support. There are actually many types of pneumatic grouting pumps used in coal mines, including those for injecting cement slurry and those for injecting chemical slurry. Today, we will talk about pumps that specialize in cement slurry.

　　IIIZBQ27/1.5 Pneumatic grouting pump for coal minesRepair Instructions

　　1. Remove the flange screws, extract the grouting cylinder, and if necessary, unscrew the grout cap.

　　2. Loosen the nuts at both ends of the small piston rod and remove the small piston rod.

　　3. Remove the bolts between the pump body and cylinder, and separate the pump body from the cylinder.

　　4. Unscrew the cap nut on the top of the cylinder.

　　5. Push the piston to the deepest part of the cylinder, unscrew the transmission rod from the piston, and then unscrew the exposed control rod.

　　6. Screw the piston rod into the piston a few more times and pull the piston part out of the cylinder.

　　7. Check the intake and exhaust valves on the piston to ensure they are sturdy, clean, and have reliable sealing. The gap between the sealing surfaces of the two intake valves and the piston plane is between 3-4mm, and the intake valve stem is not loose.

　　8. Check the wear and damage of each component and replace it if necessary.

　　9. Clean the accumulated dirt on each component, apply lubricating grease to the surfaces that move relative to each other, and then proceed with assembly

　　1. Connect the oil pot in series with the intake pipeline, unscrew the oil pot nut, add lubricating oil, use a screwdriver to tighten the screws inside the oil pot, then reverse a small angle to obtain a satisfactory amount of lubricating oil, and then tighten the oil pot nut.

　　2. The pressure gauge and the pressure gauge socket are sealed with oil and are usually not removable.

　　3. The pressure gauge pipe joint is connected to the grouting port on the tunnel wall. When it is stopped from use, it should be thoroughly cleaned immediately. If necessary, the pressure gauge seat can be removed. The material accumulated at the diaphragm should not be damaged by sharp tools.

　　Before disassembling the discharge pipe, the pressure relief valve should be opened first to relieve pressure.

　　5ZBQ27/1.5 Pneumatic grouting pump for coal minesThe principle of focusing on cement slurry:

　　Compressed air enters the cylinder through a ball valve, a binary air source, and a two position five way directional valve, pushing the cylinder piston to make reciprocating motion. Due to the connection between the cylinder rod and the slurry cylinder rod, the reciprocating motion of the cylinder piston also drives the reciprocating motion of the slurry cylinder piston to complete the suction and discharge action. The direction change is controlled by a dial installed on the cylinder rod, which moves the stroke valve back and forth to change the direction of the cylinder's intake and exhaust, and continuously completes the reciprocating motion of the cylinder piston.
