Abstract
The invention relates to a hydraulic dual-fluid grouting pump, in particular to a grouting pump used for grouting, plugging water and filling gaps in gas coal mines, shaft building and underground waterproofing work. According to the hydraulic dual-fluid grouting pump, a gear pump is driven by a motor to rotate; high pressure oil is fed into an oil cylinder through an overflow valve and a reversing valve and is reciprocated in the oil cylinder through a reversing mechanism; and meanwhile, piston rods are used for driving pistons in a grouting cylinder to synchronously reciprocate, so that the grouting is realized. The hydraulic dual-fluid grouting pump has the advantages that the setting time of grout can be mastered, the pressure can be automatically adjusted, and the hydraulic dual-fluid grouting pump is convenient to use.
Description
Technical field
The present invention relates to a kind of grouting pump, be particularly applicable to coal containing methane gas ore deposit, shaft building and down-hole waterproofing project, the cutting in tunnel and maintenance, build dam, large bridge, the based process of tall building and the hydraulic double-liquid grouting pump of all kinds of underground engineering.
Background technique
At present, the grouting for water blocking during gassy colliery both domestic and external, shaft building and down-hole waterproofing project, Large-scale Railway and vcehicular tunnel, reservoir dam basis, high-rise are basic, filling the grouting reinforcement of space, broken rock, is all implemented by grouting pump.Like this, not only increase speed of production, also improve structural quality simultaneously.But original grouting pump is in the set time of slurries, and grouting pressure aspect all cannot control voluntarily, does not reach original slip casting effect.
Summary of the invention
Object of the present invention, is to provide one and realizes two fluid grouting, can operate the set time of slurries, simultaneously according to the hydraulic double-liquid grouting pump being regulated pressure by the rock stratum situation of slip casting voluntarily.
The present invention is realized by following approach: this hydraulic double-liquid grouting pump is made up of permissible motor, coupling, gear oil pump, fuel tank, split type control valve (relief valve, unloading valve, selector valve), oil cylinder, grouting cylinder, valve chamber, changement, high-pressure rubber pipe, return tube, water cooler, pulp-absorbing pipe, midge halter, discharge pipe, mixer, anti-shock pressure meter.Motor is by shaft coupling transmission, and driving gear pump rotates, and the hydraulic oil in fuel tank is sucked gear pump and discharges, the high pressure oil of discharge, and through relief valve, selector valve, high-pressure oil pipe sends into oil cylinder, promotes piston, makes its to-and-fro motion.Oil return flows into water cooler through return tube, and return fuel tank after cooling and complete a circulation, oil cylinder is connected with grouting cylinder by piston rod, therefore two-cylinder piston does synchronous reciprocating motion, thus make slurries through suction, plasma discharge pipeline and valve chamber, suck and discharge, finally making slurries inject in injected hole.
The grouting cylinder of above-mentioned hydraulic double-liquid grouting pump, can respectively connect a valve chamber, realize slip casting by the reciprocating motion of the pistons in grouting cylinder at two ends.Can install a valve of sizing mixing additional between the midge elbow of a valve chamber and pulp-absorbing pipe wherein during two fluid grouting, this valve of sizing mixing can adjust flux arbitrarily, to reach required proportioning.
The anti-shock pressure meter of above-mentioned hydraulic double-liquid grouting pump, is provided with two pieces of anti-shock pressure meters, one piece of side being arranged on relief valve, is used for measuring the pressure of pressurized oil system; Another block is installed on the mixer, is used for measuring the pressure of slurries.Anti-shock pressure meter impact resistance manyfold stronger than ordinarily manometer, is especially used on single duplex double action pump, has superiority significantly, thus can reflect the working state of pump accurately.
The split type control valve of above-mentioned hydraulic double-liquid grouting pump is made up of relief valve, unloading valve and two-position four way change valve valve, relief valve and unloading valve not only can make pressure regulator valve but also can be used as safety valve, its effect can be as required, grouting pressure is set up arbitrarily within the scope of nominal pressure, and energy pilot pressure is constant, can raise by limiting pressure again simultaneously, play safety effect.The high pressure oil flowed out through gear pump flows into oil cylinder by two-position four way change valve, utilizes oil pressure that in-oil cylinder piston is moved reciprocatingly, and makes commutation flexibly, fast, accurately, reliably.
The present invention has following advantages: the present invention is all-hydraulic, and single, double liquid is dual-purpose, adjustable-pressure grouting pump.Have volume little, lightweight, flexibility and reliability, can grasp the set time of slurries voluntarily, the feature such as to be widely used.
