Grout Injection Pump|Double fluid and high pressure variable used in grouting construction
Grout Injection Pump is a stable and durable high-pressure injection pump, can transport large concentrations of cement slurry, yellow mud, oil and water and other media.
1. Mainly used for charcoal, railway, metallurgy, hydropower and other departments of the underground work in the excavation of the face (oblique, vertical, flat) to grout water shutters, nudes or seaside wall plugging water. Maintenance, easy to operate. After hundreds of different conditions under the use of underground grouting works, the effect is very good.
2. 2TGZ-60/210 double liquid speed high pressure grouting pump is the construction equipment, underground engineering, water conservancy projects, environmental engineering, municipal, subway, tunnel, culvert project seepage plug construction, crack reinforcement of the preferred equipment, Professional water seal construction of the best choice.

1, before the use of pneumatic driven injection pump to be used before the test pump, the duct, suction pipe, the pulp pipe is connected, open the pump for water test pump, observe the operation of the injection pump, the normal after Note Slurry operations. Common problems for the tracheal connection error, grouting pump can not be normal suction. If the quick connection is used, it is necessary to weld the quick connector (usually Φ25mm) at the inlet of the injection pump. If the connection is made with the horse mouth, pay attention to the diameter of the downhole pipe and the note Inlet diameter of pump. Connect the air duct before the first pressure air drainage, the wind pipe in the water blow clean before connecting the injection pump, so that the wind pipe dirty water into the injection pump to cause damage.
2, should always pay attention to the pressure gauge instructions, such as pressure gauge instructions or more than pressure, the safety device does not work, should identify the cause, clear the fault and then start.
3, the need to wear the tool with the need to prepare pneumatic driven injection pump the tools used in addition to the pump comes with special tools need to have a pair of vise (needle nose pliers, flat nose pliers each one), 16, a wrench, 18 pipe wrench two, screwdriver (plum, a word each) two.
4, note that the pump and the motor structure is normal, when found any fault, should immediately stop, open the drain valve to make the pressure drop, troubleshooting.
5, after mixing the slurry into the pump should be determined by the consistency of the consistency of the test will be vertical and pulp surface, easy to lay down to self-weight sink.
6, should always pay attention to make the packing does not make the Grande pressure phenomenon. Such as compression still leakage phenomenon, as the case may replace the packing or piston.
7, the Grout Injection Pump up and down the well transport Notes injection pump up and down the transportation process, to muffler (a total of six), pressure gauge (a), U-type hose (two), gas nozzle vulnerable loss Parts removed, with tools such as bringing down the well to prevent damage or loss, the interface with a good cotton block
8, after the end of each class stop, you must immediately pump water, clean the pipe and pump the internal until the clean, to ensure that the ball valve, slurry mouth, suction pulp mouth, drain valve clean and smooth.
9, grouting volume recorded to the grouting drilling compiled number, record each grouting hole grouting volume and the final pressure of grouting, conditional on each grouting pipe hanging on the card.
