Abstract
Provided is an oil cooling AC generator housing seal test apparatus. The lower end of a generator housing is in seal connection with a venthole in a base through a large intubation tube and a large rubber ring; and the upper end of the generator housing is in seal connection with a pipeline block through a small intubation tube and a small rubber ring. The upper and lower ends of the generator housing are in sealing connection through pipelines, allowing the generator housing to form an enclosed cavity. Air enters through an air inlet and enters the enclosed cavity through an air incoming pipe. The base is also provided with a plurality of support bars. The upper ends of the support bars pass through an upper clamp plate, and the upper clamp plate is fixed to the upper end of the generator housing through nuts. According to the oil cooling AC generator housing seal test apparatus, the oil cooling generator housing forms the enclosed cavity through pipeline sealing connection; and when the enclosed cavity is inflated and pressurized, airtightness of the generator housing can be detected by monitoring the pressure change via a pressure gauge. The oil cooling AC generator housing seal test apparatus is simple in structure, is convenient to use, and does not need to detect the airtightness of a finished generator, thereby saving work time and improving work efficiency.
Description
Technical field
The present invention relates to tightness test device, particularly oil cooling alternator body seal test device.
Background technology
The airtight method of existing inspection oil cooling alternator normally product is repaired general assembly complete after on bulk testing platform, whether the duty of simulation generator, after carrying out work for a long time, observe generator surface has Seepage to check the sealing of generator.If find, generator has Seepage, then need generator again to carry out overhaul, the method wastes time and energy, and considerably increases the workload of maintainer.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of oil cooling alternator body tightness test device, solves in prior art the sealing needing the method that generator observes generator whether seepage by analog operation state on testing table to be checked generator.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: generator housing is fixed on base, generator housing lower end is connected with the vent seal on base with two large cushion rubbers by two large intubate, generator housing upper end is tightly connected by little cushion rubber and pipeline block on two spiles and two, the upper and lower two ends of generator housing are connected by line seal makes generator housing form an airtight cavity, gas enters from air intake opening, enter in airtight cavity by draft tube, base is provided with multiple support bar, train wheel bridge is fixed on the upper end of generator housing through train wheel bridge by post upper by nut.
Described draft tube is provided with tensimeter and ball valve.
Described support bar is at least three, and post upper is provided with external thread, and support bar lower end is weldingly fixed on base.
Described large intubate, large cushion rubber, spile and little cushion rubber are respectively two.
Oil cooling alternator body tightness test device provided by the invention, being connected by line seal makes oil-cooled generator housing form an airtight cavity, inflating pressure in airtight cavity, detects the sealing of generator housing by tensimeter monitoring air pressure change.Structure of the present invention is simple, easy to use, without the need to carrying out the detection of close property to finished product generator, saving the working time, improve work efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention.
In Fig. 1: base 1, support bar 2, little cushion rubber 3, spile 4, pipeline block 5, train wheel bridge 6, nut 7, generator housing 8, large intubate 9, large cushion rubber 10, tensimeter 11, ball valve 12, draft tube 13, air intake opening 14.
Embodiment
As shown in fig. 1, oil cooling alternator body tightness test device, generator housing 8 is fixed on base 1, generator housing 8 lower end is connected with the vent seal on base 1 with large cushion rubber 10 by large intubate 9, generator housing 8 upper end is tightly connected with pipeline block 5 by spile 4 and little cushion rubber 3, generator housing about 8 two ends are connected by line seal makes generator housing 8 form an airtight cavity, gas enters from air intake opening 14, enter in airtight cavity by draft tube 13, base 1 is provided with multiple support bar 2, train wheel bridge 6 is fixed on the upper end of generator housing 8 through train wheel bridge 6 by support bar 2 upper end by nut 7.
Described draft tube 13 is provided with tensimeter 11 and ball valve 12.
Structure thus, by spile 4, little cushion rubber 3 and large intubate 9, large cushion rubber 10, generator housing 8 upper and lower side is tightly connected with base and pipeline block respectively, generator housing 8 is made to form an airtight cavity, opening ball valve 12 allows gas be entered by air intake opening 14, enter in airtight cavity by draft tube 13, judge whether generator housing 8 has seepage, and can sealing meet technical requirement by observing tensimeter 11 pressure value after pressurization.
Ball valve 12 can control the switch of gas-pressurized as required, makes gas inlet and outlet.
The Main Function of intubate and cushion rubber makes generator housing 8 upper and lower side connect into the pipeline of sealing with pipeline block 5 and base 1 respectively, makes generator housing 8 form airtight cavity.
Described support bar 2 is at least three, and support bar 2 upper end is provided with external thread, and support bar 2 lower end is weldingly fixed on base 1.By three support bars 2, train wheel bridge 6 is connected with base 1, the inner space of placing generator housing 8 can be formed between train wheel bridge 6 and base 1.The external thread of support bar 2 upper end can make nut 7 be fixed on support bar 2 upper end, makes train wheel bridge 6 upper end being pressed in generator housing 8 tightly, the airtight cavity of generator housing 8 is more sealed by clamp nut 7.
Described large intubate 9, large cushion rubber 10, spile 4 and little cushion rubber 3 are respectively two.
The step using said apparatus to carry out generator housing tightness test is:
First underproof oil cooling alternator body 8 is fixed on base 1, by large intubate 9 and large cushion rubber 10, the lower end of base 1 upper vent hole and oil cooling alternator body 8 is tightly connected, the upper end of oil cooling alternator body is tightly connected with pipeline block 5 by spile 4 and little cushion rubber 3, oil-cooled generator housing about 8 two ends are connected by line seal makes generator housing 8 form an airtight cavity, then support bar 2 is installed, train wheel bridge 6, fastening nut 7 makes train wheel bridge 6 upper end being pressed in oil-cooled generator housing 8 tightly, open ball valve 12, gas enters in the airtight cavity of oil cooling alternator body 8 by air intake opening 14 by the draft tube 13 in base 1, subsequently to the gas boosting in generator housing 8, pressurization is stopped when the force value of tensimeter 11 reaches 2.06MPa, close ball valve 12 and keep 1 minute, generator housing 8 surface is detected with or without leakage phenomenon by observing tensimeter 11 numerical value, as normal in tensimeter 11 numerical value, generator housing 8 No leakage phenomenon can be judged, sealing is good, now open ball valve 12 Exhaust Gas and namely complete tightness test.
