Series of two-fluid pneumatic injection pump prototype is a pulp cylinder rod chamber and the rod chamber double solution grouting pulp cylinder piston wear double slurry will be mixed in the cylinder, resulting in blocking the pump, blockingtube. My company after years of field fumble and several improvements designed to form a two-cylinder independent agency is reliable, easy maintenance, a new type of two-fluid pneumatic injection pump, maintain a prototype pumping performance, improved inadequacies, and achieved good social benefits and economic benefits of the company. Existing generic product in the market today. However, we do not take this as sufficient generation dual hydraulic pneumatic injection pump has been generated, after the improvement of the main valve, replaced with a Manifold the external connection piping and stroke valve, shape simple, reliable and institutions are goes a step further, welcome friends advice, adoption.
The series injection pump can be used for underground rock bolting in grouting the tunnel boring ahead of the guide rod support grouting borehole wall water shutoff and broken rock consolidation grouting, water dams, railway roadbed reinforcement grouting. The series injection pump grouting pressure and flow rate is inversely proportional to the the soft features slurry transport function, high efficiency. Shallow grouting can effectively play the role of protective rock structure unchanged.
