Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further illustrated:
As Fig. 1, shown in Fig. 2, prevent the device of hydrostatic testing machine top petrol tank oil spout, by hydrostatics testing headstock 1, master cylinder 2, top petrol tank 3, return tube 1, return tube 25, oil inlet pipe 6, pumping plant fuel tank 7, supplement fuel tank 8, bolt 9, sealing gasket 10, flow-off 11, pipeline support 12 and filling valve equipment 13 form, master cylinder 2 is arranged on hydrostatics testing headstock 1, supplement fuel tank 8 and be arranged on top petrol tank 3 tops, pumping plant fuel tank 8 is connected with master cylinder 2 by oil inlet pipe 6, master cylinder 2 output terminals are connected with top petrol tank 3 by return tube 1, top petrol tank 3 output terminals are connected with pumping plant fuel tank 7 by return tube 25, forming oil circuit closed loop flows, flow-off 11 is arranged on the position, boundary of return tube 25 and top petrol tank 3, pipeline support 12 is arranged on the centre of return tube 25 bottom top petrol tanks 3 and pumping plant fuel tank 7.
Return tube one 4 diameters are Φ 159 × 4.5mm, and return tube 25 diameters are Φ 80 × 3mm, and oil inlet pipe 6 diameters are Φ 33 × 2.5mm.
The operating method of the device of oil spout while solving the work of hydrostatic testing machine top petrol tank, by increasing return tube 25 diameters, increase the volume of top petrol tank 3, change return tube 25 and be connected connecting line path with top petrol tank 3, prevent that fuel injection event from producing, concrete steps are as follows:
1) before transformation, the Φ 159x4.5 return tube 4 from master cylinder 2 to top petrol tank 3 is larger than Φ 50x3 return tube 25 diameters from top petrol tank 3 to pumping plant fuel tank 7, during quick oil return, do not mate, oil return speed is slow, increases the diameter of Φ 50x3 return tube 5 two, making diameter is 80mm, and wall thickness is constant;
2) the oil storage volume of increase top petrol tank 3, improves flow-off position, and reserved retraction volume equates with the volume of master cylinder 2, avoids the not enough generation of the oil storage space fuel injection event of master cylinder 2 top petrol tank 3 that moment causes when the too much also quick return of oil storage;
3) mounting point of top petrol tank 3 is above the ground level 1.5 meters, 2.3 meters from flow-off 11 positions of top petrol tank 3 far from ground of return tubes 25, pumping plant fuel tank 7 and apart 3 meters of top petrol tanks 3, but in the middle of two fuel tanks, there is the filling valve equipment 13 of water system, when therefore return tube 25 is installed at the scene, line arrangement will get around this equipment, and then approximately 6 meters of ground distances and have 4 elbows get back to the pumping plant fuel tank 7 that is positioned at high 1.5 meters of, oil return resistance is very large, has reduced oil return efficiency.For reducing oil return resistance, by installation pipeline support 12 between two fuel tanks, return tube 25 is aloft directly connected top petrol tank 3 with in the middle of pumping plant fuel tank 7;
4) volume of top petrol tank 3 is calculated, the flow-off below retraction volume of finding top petrol tank 3 is 1/3rd of master cylinder 2 volumes, if hydrostatic testing machine normally advances with return in 200mm when pressure testing, top petrol tank 3 leave retraction volume meet and be difficult for oil spout, but in actual production because operator is many times for saving the usually not return of cylinder bar of master cylinder 2 after pressure testing of pressure testing time, Guan Junxu of the every examination of high pressure oil of pumping plant fuel tank 7 is to oiling in master cylinder 2, 7～8 left and right of accumulative total, if run into the cylinder bar initial position of being longer than master cylinder 2 until pressure testing steel pipe tube end position when entering hydrostatic testing machine, master cylinder needs return to exceed 200mm, recirculating oil quantity now will exceed the reserved master cylinder of top petrol tank 3 1/2nd three volume, there is oil spout.Solution is predetermined operation work technique, each pressure testing finish rear master cylinder 2 must return 200mm in, when steel pipe carries out hydrostatic testing machine, tube head position does not allow to exceed 200mm, if exceeded with hoist the pressure testing steel pipe centering of slinging.
As shown in Figure 2 and Figure 3, increase the oil storage space of top petrol tank 3, reserved retraction volume equates with the volume of master cylinder 2, solve master cylinder 2 in oil storage too much and the not enough fuel injection event that occurs of oil storage space of the top petrol tank 3 that moment causes during quick return, supplement fuel tank 8 and connect into entirety by connecting bolt 9 and sealing gasket 10 and top petrol tank 3.
