Pneumatic Dual Fluid Injection Pump With Three Pumps

Pneumatic double - fluid injection pump accessories product introduction

3 zbqs12/10 mine pneumatic dual fluid injection pump grouting pump accessories are set multidisciplinary advanced technology developed a new kind of grouting equipment, mainly used in mines, tunnels, water and electricity, the subway, building, bridge construction project, pneumatic dual fluid injection pump is used for crushing rock grouting consolidation, water plugging and fill the gap of engineering construction;Eliminate the underground hidden danger in flood fighting and rescue.Mine pneumatic dual fluid injection pump accessories with compressed air as power source, because of the cylinder and cylinder has great effect of the grouting area ratio, with smaller pressure can make the grouting cylinder produces high grouting pressure.Each cylinder vertical arrangement, and the stress condition is good, the reciprocating movement of the cylinder adopts advanced built-in control valve, bidirectional drive, safe and reliable, the volume rate is greatly increased, low gas consumption, energy saving effect is remarkable, the grouting cylinder as the single pole double-acting cylinder, which can realize continuous slurry, compressed oxygen self-rescuer,slurry mixing, grouting pressure fluctuation is small.we can supply the air cannon , pneumatic diaphragm ,electrical machinery.

Technical characteristics of pneumatic double fluid injection pump fittings

Outstanding advantages of this series of grouting pumps: advanced structure, high rated grouting pressure, high efficiency, convenient movement and maintenance;High pressure, large displacement is a multi - function pump.

Complete function. It can be filled with either a single group of slurry or a double group of slurry.Both chemical slurry can be injected and cement slurry can be injected.Each cylinder works synchronously, mixing ratio can be adjusted, mixing slurry is even, still can act as emulsion pump or high pressure pump, hydraulic pump and so on, used for other occasions.underground mining rail car,coal mining tunnel locomotive .
Good safety. It can be used safely in places with high variations in inflammable, explosive, temperature and humidity.mine car arrester

According to the different needs of customers to adjust parameters, meet different pressure, flow, multicomponent slurry mixing ratio and the special requirements of different media: can work three cylinder or cylinder can realize 4:1 or slurry mixing ratio of 1:1.

Structural characteristics and working principle of pneumatic dual-fluid injection pump accessories

Mine pneumatic dual fluid grouting pump accessories with compressed air as power source, because of the cylinder and cylinder has great effect of the grouting area ratio, with smaller pressure can make the grouting cylinder produces high grouting pressure.

Each cylinder vertical arrangement, and the stress condition is good, the reciprocating movement of the cylinder adopts advanced built-in control valve, bidirectional drive, safe and reliable, the volume rate is greatly increased, low gas consumption, energy saving effect is remarkable, the grouting cylinder as the single pole double-acting cylinder, which can realize continuous slurry, slurry mixing, grouting pressure fluctuation is small.

Pneumatic dual - fluid injection pump maintenance instructions

Be sure to remove 3 screws from the fixed pressure gauge (1.6mpa) on the cover, remove the PU pipe behind the pressure gauge, and remove 8 screws from the cover before removing the cover.

Screw down the nut that fixed the grouting tank, and then screw down the nut that fixed the grouting cylinder piston rod and piston rod drive block.

3, the grouting cylinder screw on cap unscrewing, large (small) into the first pulp box from large (small) grouting can be removed, must take out large (small) into pulp after mouth sealing washer, then the piston rod pumped from grouting cylinder, otherwise easy to damage the piston sealing ring.

Unscrewed the large (small) grouting cylinder screw cover, take out the piston rod, on the other side with special nylon rods or copper bar, the piston rod combination ring (axis) from grouting cylinder ejector (small circle grouting cylinder assembly is the small piston rod combination (axis) from grouting cylinder ejector).

Special attention should be paid to the installation direction when replacing the sealing rings of the grouting cylinder, and the sealing rings should not be damaged.

Remove the four nuts of the upper cover of the cylinder and open the cylinder.

Remove the screw from the upper cover of the cylinder to open all components of the pneumatic valve.

Pneumatic double fluid injection pump equipment maintenance

Good maintenance is the prerequisite to ensure the normal operation of the equipment and to extend the service life.Regularly add lubricating oil to the lubricating point of grouting pump for tightening, adjustment and maintenance.After proper maintenance, the catalyst hose should be replaced after about 10 tons of grouting materials are used.About 20 tons of grouting material will require replacement of worn piston parts and seals.
