Embodiment Construction

[0011] The hydraulic double-liquid grouting pump includes oil tank (1), anti-seismic pressure gauge (2), high-pressure rubber hose (3), valve chamber (4), slurry discharge joint (5), slurry suction joint (6), grouting cylinder (7 ), reversing mechanism (8), oil cylinder (9), two-position four-way reversing valve (10), unloading valve (11), overflow valve (12), three-way elbow (13), gear pump ( 14), oil return hose (15), water cooler (16), coupling (17), motor (18). The technical points are: the motor (18) is connected to the gear pump (14) through a coupling (17), the gear pump (14) and the oil tank (1) are connected by a rubber tube, and when the gear pump (14) rotates, the oil is transferred from The oil tank (1) is sucked into the gear pump (14) through the filter, and one end of the overflow valve (12) is connected with the gear pump (14) and the two-position four-way through the high-pressure rubber hose (3) and the three-way elbow (13). The valve (10) is connected, and ...

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 [0001] The invention relates to a grouting pump, in particular to a hydraulic double-liquid pump suitable for excavation and maintenance of gas-containing coal mines, construction of wells and underground waterproofing projects, tunnels, construction of dams, large bridges, foundation treatment of high-rise buildings, and various underground projects. Grouting pump. Background technique [0002] At present, domestic and foreign gas coal mines, well construction and underground waterproofing projects, large-scale railway and highway tunnels, reservoir dam foundations, grouting water blocking in foundations of high-rise buildings, filling voids, and grouting consolidation of broken rock formations are all Implemented by grouting pump. In this way, not only the speed of production is increased, but also the quality of the building is improved. However, the original grouting pump cannot control the solidification time of the grout and the grouting pressure, and...
