Custom Mine Pneumatic Grout Pump 20L/Min To 50L/Min Pneumatic Injection Pump

Mine Pneumatic Grout Pump Support Customization

Features of Pneumatic Injection Pump

1. The pump has an advanced structure, high-rated output pressure, large displacement, high efficiency, easy to move, and easy to use and maintain;
2. Full-featured, that is, it can inject single-component slurry or two-component slurry; it can be injected with chemical slurry or cement and other slurries; each cylinder works synchronously, the mixing ratio can be adjusted, and the mixing is uniform; and It can be used as an emulsion pump, hydraulic pump, etc. for other occasions;
3. Good safety, can be used safely in places with flammable, explosive, temperature, and humidity changes;
4. The parameters can be adjusted according to the different needs of customers. Meet the special requirements of different pressures, flow rates, and different conveying media;
5. It can work with three cylinders or two cylinders to achieve the requirement of a 4:1 or 1:1 slurry mixing ratio. The pump has high pressure and a large output flow, which can meet the requirements of high-intensity injection.

Technical Parameter of Mining Pneumatic Grouting Pump

Installation method of Pneumatic Injection Pump

1) Before connecting the gas pipeline to the pump intake pipeline, please clean the pipeline port first, then open the gas to blow the impurities in the pipeline once, and then connect to ensure the cleanliness of the gas source.
2) Pay attention to observe that there should be lubricating oil (No. 20 oil) in the lubricator, observe the observation cup on the lubricator, and adjust the handle to make the oil dripping speed about 5~6 drops/min (the new pump has been adjusted when it leaves the factory). When refueling, first remove the cover, push down the black button on the oil cup of the lubricator, remove the cover of the oil cup, and then refuel.
2) Connect the two slurry suction pipes to the slurry suction port respectively, and fasten them with pipe hoop or iron wire to prevent air leakage.
3) Connect the two high-pressure pulp pipes to the high-pressure tee outlet with a U-shaped card.
4) Prepare a clean water tank, no less than 100L, and fill it with clean water (special cleaning agent for chemical slurry).
5) Place the two slurry suction pipes and faucets in the clean water tank, and at the same time place the slurry discharge pipe in clean water.
6) Open the intake valve, at this time the plunger rod of the pneumatic grouting pump should reciprocate, and the two grouting pipes should discharge clean water respectively.

8) After 1 minute of trial operation, if there is no abnormal phenomenon, you can connect the two grouting pipes to the combiner, the high-pressure valve, and the grouting orifice pipe to prepare for grouting.
9) Before the formal grouting, please make preparations for mixing the grouting materials and cleaning with clean water after the grouting. For the grouting materials such as cement slurry, it is required to stir evenly. Pump.
10) When working, adjust the air pressure by adjusting the round handle of the pressure-reducing valve (the pressure of the working air source can be adjusted to 0.63MPa) and adjust the reciprocating speed through the air inlet valve (if grouting for a long time, the reciprocating stroke should be controlled at 30 times/min). within). The series of pneumatic grouting pumps have the characteristics of automatic variables, that is, when the grouting pressure is low, the grouting flow rate is automatically maintained at a large value, and the grouting flow rate is automatically reduced when the grouting pressure is high. Traffic is minimal.
11) At the end of grouting, the suction and discharge pipe should be placed in clean water immediately, and the clean water should be sucked and discharged for no less than 10 minutes to ensure that there is no residual slurry in the pipeline.
