Description
Technical field
The present invention relates to a kind of magnetic float-type oil-level signalling means durability test device, the durability test device particularly in hot environment.
Background technology
The endurancing of magnetic float-type oil-level signalling means, fundamental purpose is the permanance testing the use of its internal signal switch.During test, control the change of oil pressure and oil level by the mode that people is oil extraction exhaust, make pressure signal device and the action of oil level signal device, with control oil pump by various directions running status.By testing its a series of parameter on testing table, thus draw its endurance life maximum under simulated environment.Substantially adopt the mode adding, drain the oil at present, or stepper motor drives magnetic float-type oil-level signalling means to rotate and the mode of stepper motor forward and backward promotion magnetic float is tested, its weak point is:
1. adopt automatically control to add, defuelling system, structure is more complicated, and peripheral control system makes loaded down with trivial details, and cost drops into higher.
2. when needed for product, test ambient temperature is too high, motor is in test ambient temperature and cannot works, and existingly to add, jettison gear, also cannot be suitable for, required consider and buy as high temperature resistant fuel tank, pipeline, peripheral loaded down with trivial details control system, adds, the connection of defuelling system etc. automatically; And adopt large molded breadth temperature temperature controlled environment equipment etc., considerably increase experimentation cost.
How to find a kind of for the endurancing of magnetic float-type oil-level signalling means, in hot environment, particularly carry out the not only reliable but also simple of endurancing, and detection means that can be cost-saving, become the problem that current line is anxious to be resolved in the industry.
Summary of the invention
The object of the invention is the weak point existed for above-mentioned prior art, there is provided a kind of reliable simple again, not temperature influence, experimentation cost can be saved, can fully ensure to be in the drawing mechanism axially-movable track outside experimental enviroment and the right alignment being in the signalling means magnetic float central shaft in experimental enviroment, and be convenient to regulate, and be applicable to all products of the same type.Realize magnetic float-type oil-level signalling means under various temperature environment, the device of the endurancing particularly in hot environment.
The technical solution adopted for the present invention to solve the technical problems is: a kind of magnetic float-type oil-level signalling means durability test device, comprise the signalling means main body installing mechanism that haulage gear outer with experimental enviroment is coaxially connected, magnetic float fixed mechanism and magnetic float-type oil-level signalling means, it is characterized in that: at least one the magnetic float being placed in experimental enviroment fixedly lies on the platform of described magnetic float fixed mechanism 11, signalling means axostylus axostyle is through the magnetic float center pit on magnetic float fixed mechanism 9, spacing by locking end face clip, towbar 2 and signalling means magnetic float central shaft keep right alignment, traction rope 3 is connected through the sliding guide sleeve on haulage gear 7 base plate, stay cord is fixed on the eccentric rotary axle of rotating disk, pull signalling means main body installing mechanism 9 in experimental enviroment, magnetic float fixed mechanism 11 bottom motoring ring test environment, form the relative motion with the magnetic float under stationary state, when the stepper motor 5 on the outer haulage gear of experimental enviroment drives stay cord stationary shaft 4, during traction rope tension, stepper motor 5 often turns around, magnetic float relative signal device axostylus axostyle complete one complete upper, down stroke.
The present invention has following beneficial effect compared to prior art:
Reliably, simply.Draw-gear is positioned over the mechanical connecting structure outside experimental enviroment by the present invention, completely not temperature influence, while satisfied test demand, saves experimentation cost in a large number.
The present invention adopts towbar 2 and signalling means magnetic float central shaft to keep right alignment, by reliable and simple mechanical connecting structure, can fully ensure to be in the drawing mechanism axially-movable track outside experimental enviroment and the right alignment being in the signalling means magnetic float central shaft in experimental enviroment.
The location of stay cord stationary shaft on rotating disk, the most accurately controls and ensure that the relative efficiency displacement of magnetic float on axostylus axostyle; Connected mode, makes stepper motor 5 often turn around, and just effectively can realize magnetic float relative signal device axostylus axostyle and complete a complete upper and lower stroke.Its one-piece construction advantage is that volume is little, and structure is simple, is easy to processing, installs the impact of the factor such as environment, instrument size that is not put to the test, and for the effective travel of different product, only need change Special turntable, convenient, simple.The application of eccentric rotary axle, has abandoned the required switching control rotating forward stepper motor, reverse of traditional control system, has effectively saved the former required programming of control system and components and parts material cost.。
The present invention is applicable to all products of the same type, realizes magnetic float-type oil-level signalling means under various temperature environment, the endurancing particularly in hot environment.
