Description

Intelligent Hydraulic jumbolter pumping plant

Technical field

The utility model belongs to the technical field of hydraulic power unit, is specifically related to a kind of Intelligent Hydraulic jumbolter pumping plant.

Background technology

Existing pumping plant adopts the configuration structure of single variable pump mostly.But existing single pump type pumping plant because the problem of discharge capacity deficiency can not satisfy the instructions for use of jumbolter under the coal mine, has had influence on the operating efficiency of jumbolter.

Summary of the invention

The utility model can not satisfy the instructions for use of jumbolter under the coal mine in order to solve existing hydraulic power unit, affect the problem of its operating efficiency, has offered a kind of Intelligent Hydraulic jumbolter pumping plant.

The utility model adopts following technical scheme to realize: Intelligent Hydraulic jumbolter pumping plant, comprise power part, fuel tank assembly, radiator and oil-distribution component, described power part is the double pump power set, described double pump power set comprise the duplex gear pump that is connected with fire-proof motor, two oil-outs of duplex gear pump connect respectively the oil-feed sebific duct, two oil return openings of duplex gear pump connect respectively the oil return sebific duct, two oil-feed sebific ducts connect with the oil-in of corresponding jumbolter respectively, two oil return sebific ducts connect with the oil return opening of corresponding jumbolter respectively, and an oil-out of two duplex gear pump is equipped with hand stop valve.

The utlity model has following beneficial effect: can drive simultaneously two jumbolter work, join valve with hydraulic pressure and make up the equipment that can be connected simultaneously more than 3 or 3, and can be applied to other field.The utility model is to exchange flame-proof electric motor as power, and driving a duplex hydraulic gear pump is hydraulic energy with electric energy conversion, can realize exporting one tunnel oil return or the oil return of output two-way.The pumping plant operating pressure is high, and efficient is high.

Description of drawings

Fig. 1 is structural representation of the present utility model,

Fig. 2 is the lateral view of Fig. 1,

Fig. 3 is the connection diagram of the utility model and jumbolter,

Among the figure: 1-oil radiator, 2-air filter, 3-double pump power set, 4-double pump fuel tank, 5-oil-distribution component, 6-double pump passport, the 7-perspective board, 8-oil filter, 9-pressure meter, the 10-hand stop valve, 11-jumbolter I, 12-jumbolter II, the 13-fire-proof motor, 14-duplex gear pump, 15-oil-feed sebific duct, 16-oil return sebific duct, P1, P2-oil-out, O1, O2-oil return opening.

The specific embodiment

By reference to the accompanying drawings the specific embodiment of the present utility model is described further.

The utility model mainly is comprised of power part, fuel tank assembly, radiator and oil-distribution component etc.At first add 46# and 32# antiwear hydraulic oil through air filter before the use, also can replace with the machinery oil of identical viscosities.But the working oil of two kinds of different models must not load in mixture, and liquid level is advisable in the middle and upper part of oil ga(u)ge.By flame-proof switch fire-proof motor is connected to 380, on the power supply of 660V, places in the distance of main frame (20 ~ 40) rice, two sebific ducts are received respectively P1 mouth and P2 mouth, other two sebific ducts are received respectively O1 mouth and O2 mouth.Two sebific ducts of drawing from same pump are connected respectively to oil-in and the oil return opening of corresponding rig.

Connecting can starter motor after complete, and it is identical with turning to of demarcating to observe whether turning to of every oil pump, otherwise intersects power line.The outlet of every oil pump all is furnished with pressure-regulating valve.Wherein hand stop valve is equipped with in the outlet of an oil pump, when pumping plant only drives bench drill machine work, uses the oil pump that is unkitted hand stop valve to be used as power, and the stop valve of another oil pump is unclamped, and makes it to be in the drain charge state.If drive simultaneously two bench drill machine work, stop valve closed.

Claims (1)
