液压式注浆泵工作原理及工程应用

Working principle and engineering application of hydraulic grouting pump

液压式注浆泵由电动机、齿轮油泵、溢流阀、液压换向阀块、油缸、工作缸、混合器以及油箱、散热器、油滤器、进排阀和电控箱等部件组成。液压式注浆泵由电动机直接驱动齿轮油泵，齿轮油泵输出的高压油液经溢流阀进入液压换向阀块，由液压换向阀块控制油缸做往复运动，由于油缸与工作缸是同步运动，又因工作缸的缸径行程都与油缸相同，所以工作缸的排量和压力基本与油缸相近，工作缸的两端各有一套吸浆阀和排浆阀，即可以吸排同一种浆液，也可以分别吸排两种不同的浆液。

The hydraulic grouting pump is composed of motor, gear oil pump, overflow valve, hydraulic reversing valve block, oil cylinder, working cylinder, mixer, oil tank, radiator, oil filter, inlet and exhaust valve and electric control box. The hydraulic grouting pump directly drives the gear oil pump by the motor. The high-pressure oil from the gear oil pump enters the hydraulic reversing valve block through the overflow valve. The hydraulic reversing valve block controls the reciprocating motion of the oil cylinder. Because the oil cylinder and the working cylinder are in synchronous motion, and because the cylinder diameter stroke of the working cylinder is the same as that of the oil cylinder, the displacement and pressure of the working cylinder are basically similar to those of the oil cylinder Each has a set of suction valve and discharge valve, that is, the same slurry can be sucked and drained, or two different slurry can be sucked and drained separately.

Engineering application of hydraulic grouting pump

液压式注浆泵主要应用于铁路公路隧道、水利水电、地铁隧道、矿山巷道、军事设施、各种地下建筑和抢险等领域的工程施工。液压式注浆泵重点应用于顶管注浆，膨润土注浆，双液隧道注浆，地基处理下沉，地面下沉，后注浆（开塞注浆），高压注浆，二次注浆，地下室防水堵漏等工程。

Hydraulic grouting pump is mainly used in railway highway tunnel, water conservancy and hydropower, subway tunnel, mine roadway, military facilities, various underground buildings and rescue engineering construction. The hydraulic grouting pump is mainly used in pipe jacking grouting, bentonite grouting, double liquid tunnel grouting, foundation treatment subsidence, ground subsidence, post grouting (plug grouting), high-pressure grouting, secondary grouting, basement waterproof and plugging, etc.
