Pneumatic injection pump features and working principle
ZBQ type pneumatic grouting pump is mainly used in mine, subway, water conservancy construction, grouting water and broken rock formation consolidation project. It can also be used to pre-grout the working face in accordance with well depth. The pump can be used for single grout (grout), but also for the two-liquid grouting (grout, water glass), but also can be used for conveying other viscosity or corrosive not too large variety of slurry and water. But also in flammable, explosive, strong radiation, dust, temperature changes and water places can be. Pneumatic grouting pump features: (1) small size, light weight, moving handling, to adapt to frequent mobile multi-point grouting. (2) Due to the pneumatic transmission, the pump grouting performance is very suitable for large flow rate when the grouting pressure is low, and the small flow rate working condition when the grouting pressure is increased. (3) due to the use of pneumatic transmission in flammable, high explosive, water, dust and other work environment can also be used. (4) In the conditions of the slurry is not very strict requirements can be achieved using a pump double liquid grouting, greatly reducing the purchase cost of construction equipment. Working principle: Compressed air through the ball valve, gas source duplex, two five-way valve into the cylinder to promote reciprocating motion of the cylinder piston. Due to the connection of the cylinder rod and the rod of the slurry tank, the reciprocating motion of the cylinder piston also pushes the piston of the slurry tank to reciprocate to complete the suction and discharging action. Reversed by the dial mounted on the cylinder rod, back and forth toggle stroke valve to control the direction of cutting changer into the exhaust direction, the cylinder piston to complete the reciprocating motion. (1) When using this type of grouting pump for double-liquid grouting, when ordering, it shall specify the ratio of double grout to be injected. (2) The pressure of gas supply must not be less than 0.6 ~ 0.7Mpa and the gas supply amount should not be less than 0.7 m3 / min (1) When using this type of grouting pump for double grouting, when ordering, please note the ratio of double grout. (2) The air supply pressure must not be less than 0.6 ~ 0.7Mpa, the air supply must not be less than 0.7m3 / min
