DZ - Q liquid injection gun
DZ - Q liquid injection gun, individual hydraulic prop fluid injection gun, liquid injection
gun
DZ - Q liquid injection gun works: at the beginning of the supporting force note liquid gun into
three body, card prison lock set, tightening up the grip handlers, drive for hydraulic push
rod, open for hydraulic one-way valve, high pressure fluid along the way for the pressure gauge, a path of high pressure
release device cavity hole, liquid pipe, three with injection valve pillar into inferior vena, pillar
live cylinder force increases, when the end of the pillars and the top beam contact, close to
the roof, depending on the pressure gauge index size; If the pressure reaches the provisions
of this working face roof pressure, speed stop for liquid, external driving force, moment
driverunload coping bar, open the pressure relief valves, high pressure fluid by releasing hole
eduction, the pressure in the gun is zero, well take a gun.
