Description
Technical field:
The present invention relates to a kind of pick-up unit, particularly relate to a kind of swivel adapter head oil circuit pick-up unit.
Background technology:
Swivel adapter head has three hydraulic fluid ports to be connected with workshop pipeline usually, is in A mouth, B mouth and Y mouth respectively.The shell of three hydraulic fluid ports and swivel adapter head is static connection.Shell keeps relative to not rotating with uncoiler or coiling machine.The diameter of axle is less than the diameter of shell, and the gap between the cylinder barrel of its gap and general hydraulic cylinder and piston is suitable.Because the reason of installing makes swivel adapter head can produce swing in rotary course, two bearings for bearing the axial force produced when shell swings, and make to keep gap between axle and shell.The material of rotary seal is wear-resisting compound substance or metal material, and rotary seal is installed between axle and shell.Rotary seal can bear high pressure, usually can reach 200bar, and material is comparatively hard, and sealing property is bad.Oil sealing is framework lip-shaped sealing, can not bear too high pressure, usually can not more than 3bar, but it has good sealing in low-voltage high speed situation, and the Leakage Energy from rotary seal is closed in its effect.Leakage Energy must be flow back in fuel tank, to protect oil sealing not damaged when very low-pressure.
Therefore, swivel adapter head must carry out strict detection before dispatching from the factory, and not only will detect its whether leakage of oil under working pressure, also will detect the maximum pressure that oil sealing can bear.Traditional detection method is detected swivel adapter head by special high pressure pumping station, and special high pressure pumping station investment is large, and occupation area of equipment reaches, heavy again, operation inconvenience, very flexible.
Summary of the invention:
It is simple that the object of the invention is to provide a kind of structure, swivel adapter head oil circuit pick-up unit easy to use.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of swivel adapter head oil circuit pick-up unit, comprise storage tank, communicating pipe, draft tube, control tube, gas outlet, tensimeter, flowline and hydraulic oil flexible pipe, a vertical communicating pipe is welded with on the top of storage tank, the control tube of a level is welded with on the top of communicating pipe, one end of control tube is connected with draft tube, and the other end is connected with gas outlet.Have a flowline at the bottom welding of storage tank, the outer end of flowline is connected with hydraulic oil flexible pipe, and flowline is provided with a tensimeter, is convenient to the pressure size of observing hydraulic oil.
Further, described storage tank adopts existing liquid gas storage tank, and raw material is easy to get, good pressure-resistant performance, conveniently moving, is easy to processing.
Further, described communicating pipe is heavy wall seamless metal pipe, and bearing capacity is strong, and be easy to welding, the lower end of communicating pipe is connected with storage tank, and upper end is connected with control tube.
Further, described control tube is heavy wall seamless metal pipe, and bearing capacity is strong, is easy to welding, and the control tube at control tube and connecting pipe tie point two ends is respectively provided with an operation valve, for controlling air inlet and exhaust.
The invention has the beneficial effects as follows, structure is simple, easy to manufacture, low cost of manufacture, easy to use, take up room little, and be convenient to mobile, accuracy of detection is high.
Accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is unitary construction figure of the present invention.
In figure: 1 storage tank, 2 communicating pipes, 3 draft tube, 4 control tubes, 5 gas outlets, 6-7 operation valve, 8 tensimeters, 9 flowlines, 10 hydraulic oil flexible pipes.
Embodiment:
