It is mobile, inconvenient for use if volume is larger；For air-pressure type grouting pump due to structure design defect, degree of integration is not high, equipment volume
Greatly, quality weight, difficult, since the gas under mine inside high-pressure air hose contains more impurity particle, so that cylinder inner wall
And piston plate ring wear is serious, in addition the gas atmosphere stability in down-hole high pressure air hose is inadequate, so that Pneumatic grouting pump
Slip casting rate is unstable, influences grouting quality, and external device is not easy to remove cleaning, and slurry is remaining in slip casting working cylinder and check valve
Object is not easily cleaned, and is caused working cylinder and check valve to block, is influenced normal use, finally makes that grouting pump service life is short, failure
Rate is high.
Chinese patent CN203430720U discloses a kind of single hydraulic pneumatic grouting pump: " including pump bracket and be mounted in pump bracket
The pump housing in portion's support plate, it is characterised in that: the pump housing includes cylinder barrel, and cylinder barrel both ends of the surface respectively have a cylinder
End socket, the top of two cylinder end sockets are respectively equipped with a limit valve, are connected to inside limit valve and cylinder barrel；Outside cylinder barrel
Lateral roof is equipped with a gas commutating valve, and two gas vents of gas commutating valve are connected with two limit valves respectively；Cylinder
End socket both ends outer end face center is respectively equipped with a working cylinder, there is a working chamber, working chamber and gas in the working cylinder
Working cylinder plug is equipped between cylinder inner wall of cylinder；A piston plate, piston plate both ends of the surface centre bit are equipped with inside cylinder barrel
It sets and is respectively provided with a piston rod, the piston rod passes through working cylinder plug and extend into inside working chamber, in piston rod and working chamber
Wall is fitted close and can slide；Each working cylinder outer wall is respectively provided with a slurry-feeding hole and a pulp by the symmetric position of proximal end
Hole, the slurry-feeding hole and slurry outlet are communicated to corresponding working chamber；One is equipped with outside each slurry-feeding hole into slurry check valve,
It is equipped with one outside each slurry outlet and goes out slurry check valve ", structure is still relative complex, and needs tolerance regulation ball valve to grouting pump
Be adjusted to stablize pulp rate, while the structure of external pump bracket causes grouting pump external dimensions larger, be unfavorable for transport and
The placement of small space.
