Grouting machine adopts new high-pressure perfusion to stop leakage
Published Time:2014.01.16 Views No.

The double liquid grouting pump can carry out two kinds of grouting methods: single liquid grouting (cement slurry) and double liquid grouting (cement slurry, water glass), and also can transport corrosive liquid. It can also be used in places where environmental changes are large and bad. After the continuous improvement of our company, has the double liquid grouting pump upgrade from the basic function of the original to a better level, the main features are: small size, easy to carry mobile, suitable for mobile multi point injection. Pneumatic drive is adopted to make grouting pump obtain large flow at low grouting pressure, and the technique of obtaining small flow rate when grouting pressure is high. Pneumatic transmission, flammable, high explosive, water, dust and other work environment can also be applied. Under the condition that the slurry ratio needs less, the pump can be completed by using a pump, which greatly reduces the cost of construction.
The filling machine adopts the high pressure perfusion model of plugging fracture trap by using high-pressure grouting plugging agent, high pressure grouting plugging agent is a kind of polyurethane materials, there will be a strong reaction in the water after contact, closed elastic material foaming reticular, injected into the building through cracks in the grouting machine after pressure by water reaction the release of large amounts of carbon dioxide to produce two osmotic pressure, through the two kinds of pressure of the elastomeric high pressure grouting plugging agent generated is pressed into the cracks, so as to achieve a purpose to fill.
Double fluid grouting pump is a single cylinder double acting piston pump, which can transport cement, yellow mud, water glass, oil, water and other media. At the same time can transport two kinds of media, can also be transported by a single medium, stable performance, compact structure, easy operation and maintenance. Double liquid grouting pump is widely used in water tunnel, grouting coal mining working face; Water Leakage wall rock drift and concrete wall grouting; tunnel cracks, broken rock, evacuation rock reinforcement; grouting; grouting backfill and prevent landslide, ground subsidence, the building of the correct skew grouting etc.. The main technical characteristics of double liquid grouting pump: single cylinder double acting, piston reciprocating once, can realize the suction and discharge of two kinds of liquid. Hydraulic drive, reliable machine, high pumping pressure. The original reversing mechanism can also be applied to workplaces (explosion protection) with special requirements.
