Abstract
An oil leak checking device for a high-voltage circuit of a hydraulic mechanism's breaker comprises a box-type body. One side wall of the body is provided with an oil level gauge for measuring oil level. The side wall of the body is also provided with an observation window for observing the inside situation of the body. The bottom of the body is connected with an oil valve for oil injection and oil drainage through an oil tube. The top of the body is equipped with a detachable top cap which can be left open so as to put the hydraulic mechanism of the breaker therein. The observation window is arranged on the other side wall adjacent to or opposite to the side wall of the oil level gauge, and the observation window is sealingly fixed on the side wall by the use of a rubber blanket and a cover plate through bolts. The bottom of the body is provided with a stainless steel supporting seat, and four base angles are equipped with fixed bolt holes. According to the utility model, normal pressing of an oil pump is simulated, and after pressing, leak checking can be carried out on each seal valve such that the high-voltage circuit of an FX22 switch impregnates oil. Leak checking can be carried out on each seal valve after pressing, and observation can be carried out at a closing position after processing.
Description
Technical field
The utility model relates to a kind of leakage of oil testing fixture for the high tension loop of hydraulic mechanism isolating switch, the leakage of oil testing fixture of especially French Alstom FX22 type hydraulic machine mechanism circuit-breaker high tension loop.
Background technology
The fuel tank of France Alstom FX22 type hydraulic machine structure is enclosed construction, if when leaking in mechanism occurs, we are difficult to observe directly, can by observing manometric fall off rate or recording oil pump suppressing number of times and whether exceed standard in 24 hours, analyze reason and the trouble spot of judgement frequent starting according to the running status of isolating switch frequent starting.
Alstom FX22 type isolating switch emerged in operation hydraulic mechanism oil pump frequent starting fault, may be because the hydraulic circuit seepage causes, seepage is divided into and leaks outside and interior leakage, leak outside and to be seen by naked eyes, and interior leakage is not easy to be found out by naked eyes, but because fuel tank is an enclosed construction, in its pump start process, valve body has or not the leakage of oil situation so can't observe.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of simple in structure, easy to use, can suppress in order to observe analog operation state lower fuel tank internal safety valve and oil pump the leakage of oil testing fixture of the hydraulic mechanism isolating switch high tension loop of reverse checkvalve working condition.
The purpose of this utility model is completed by following technical solution, and it includes a box body, and a sidewall of this body is equipped with for the oil level indicator of measuring the oil level height, also is provided with the view window of observable body interior situation on the sidewall of body; Described body bottom is connected with a fuel tap that is used for oiling and drains the oil by oil pipe; The top of body dispose one can open wide in order to put into the removable top cover of Hydraulic Mechanism of Circuit-breaker.
Described view window is arranged on another sidewall of adjacent or relative oil level indicator sidewall, is fixed on sidewall by bolt seal by rubber blanket and cover plate; On the open ports that the top that described removable top cover is bolted on described body is offered.
The bottom of described body is provided with Stainless Steel plate supporting seat, and is provided with fixed bolt hole at four base angles.
The utility model is by a box body, through normally suppressing of simulation oil pump, and suppress complete after, can carry out each sealing valve port is hunted leak, thereby make FX22 switch high-pressure loop oil impregnate, can hunt leak to each sealing valve port after suppressing, can observe at closing position after processing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side-looking structural representation of Fig. 1.
Fig. 3 is the top view structural representation of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2,3, the utility model includes a box body 1, one sidewall of this body 1 is equipped with for the oil level indicator 2 of measuring the oil level height, also is provided with the view window 3 of observable body interior situation on the sidewall of body 1; Described body 1 bottom is connected with a fuel tap 5 that is used for oiling and drains the oil by oil pipe 4; The top of body 1 dispose one can open wide in order to put into the removable top cover 6 of Hydraulic Mechanism of Circuit-breaker.
View window 3 described in the utility model is arranged on another sidewall of adjacent or relative oil level indicator sidewall, is fixed on sidewall by bolt seal by rubber blanket and cover plate; On the open ports that the top that described removable top cover 6 is bolted on described body 1 is offered.
The bottom of described body 1 is provided with Stainless Steel plate supporting seat 7, and is provided with fixed bolt hole 8 at four base angles.
Embodiment
Press the explanation of Alstom manufacturer, the FX22 isolating switch suppressed in one day 24 hours number of times 20 times with subordinate's normal range within, and Wang Dian becomes the frequent starting of 5062 Hydraulic Mechanism of Circuit-breaker C phases and the contrast of other isolating switch, real genus abnormality.Can observe more intuitively in oil circuit pressurized situation the leak detection of hydraulic system by this leakage detection apparatus, safety valve and valve body contact face have obvious leakage of oil, and on-the-spot judgement top rubber O-ring seal loses sealing function (neglected loading O-ring seal when finding that A, C assemble for producer mutually when the disintegration overhaul of scene) because of aged deterioration.
Body frame described in the utility model is made by stainless steel, and as shown in Figure 1: oil level indicator is equipped with in the body front, is used for measuring the height of oil level.Shown in Figure 2: mechanism bottom is connected with body by oil pipe by fuel tap, be used for oiling, drain the oil.Mechanism's tank wall both-side opening is as view window.During oiling, view window is covered by rubber blanket and cover plate, by 10 bolt fixing seals.Drain oil during observation, then unclamp set bolt, open cover plate, can observe the FX22 Hydraulic Mechanism of Circuit-breaker of putting into.
Shown in Figure 3: the top is opened wide, and can put into from the top FX22 Hydraulic Mechanism of Circuit-breaker, and the part of suppressing of hydraulic mechanism is all put in this device, and fixed bolt hole is left at four jiaos, this device top, and device is fixed with bolt after putting into hydraulic mechanism.Both sides, mechanism bottom are supported by corrosion resistant plate, and are provided with fixed bolt hole at four base angles.
Put into the FX22 Hydraulic Mechanism of Circuit-breaker from testing fixture top, then open fuel tap by the fuel tap oiling, observe oil level by oil level indicator and arrive the device top, stop oiling, hydraulic mechanism is suppressed operation, suppress complete, open the fuel tap oil extraction, observe oil level indicator, after draining oil, open at last the both sides view window and just can observe FX22 Hydraulic Mechanism of Circuit-breaker leakage of oil situation.
