Abstract
The invention relates to a sealing test stand comprising a shell, end caps, a liquid medium, a rotating driving system, a pressure adjusting device and a data acquisition device. The liquid medium is arranged in the internal cavity of the shell in a sealing way. The pressure adjusting device and the data acquisition device are connected with the internal cavity of the shell. The end caps are arranged at the two ends of the shell and connected with the shell in a sealing way. The rotating driving system comprises a motor and a rotating shaft. The motor drives the rotating shaft. One end of the rotating shaft is contacted with the liquid medium, and the other end of the rotating shaft is contacted with air. The rotating shaft and the shell are connected in a sealing way. The sealing test stand is simple in structure and convenient to assemble and disassemble, and liquid is pressurized so that the sealing test stand is safe and reliable, static sealing and dynamic sealing can be verified by greatly simulating the actual working condition of the product, and the recorded data can be displayed in real time by the data acquisition module and the sealing situation can be fed back.
Description
Technical field
The present invention relates to a kind of testing table verifying properties of product, particularly relate to a kind of motive seal testing table, belong to the applied technical fields such as leakage test.

Turn motive seal under water in the equipment such as robot Application comparison extensive.In different systems, for different request for utilizations and periphery actual working environment, the parameter such as moment of torsion, frequency, working pressure, working temperature of turning axle is different.Low temperature resistant, reciprocating rotary sealing is well the important indicator that some subsea equipments need to ensure.But in prior art, undesirable to the performance verification effect of subsea equipment, the performance index that cannot truly feed back, can not meet actual user demand.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide the leakage test platform of a kind of slow-speed of revolution, low temperature resistant, reciprocating rotary, solve the problem that prior art performance verification effect is undesirable.
The technology of the present invention solution:
Testing table comprises housing, end cap, liquid medium, rotary drive system, pressure regulation device, data acquisition unit, liquid medium sealing is arranged on housing cavity, pressure regulation device, data acquisition unit are connected with housing cavity, and the two ends that end cap is arranged on housing are connected with housing seal; Rotary drive system comprises motor and turning axle, and motor drives turning axle, and turning axle one end contacts with liquid medium, and the turning axle other end contacts with air, is tightly connected between turning axle and housing.
Described liquid medium is cryogenic liquid, and temperature range is 1 DEG C-30 DEG C.
Be provided with annular seal groove between described end cap and housing, in annular seal groove, lip-type packing be installed.
Lip circle and Glais ring is adopted to seal between described turning axle and housing.
Described pressure regulation device adopts hydraulic hand-pump.
Advantageous effect of the present invention is as follows:
Structure is simple, and mounting or dismounting are convenient; By to liquid pressing, safe and reliable, static seal and motive seal can well be verified by analog equipment actual condition, and have data acquisition module to show record data in real time, feedback sealing situation.Demonstrate the rationality of static seal, the sealing of dynamic-sealing rotary axle construction under water, actual user demand can be met.

Be provided with annular seal groove between described end cap and housing, in annular seal groove, lip-type packing be installed.
Lip circle and Glais ring is adopted to seal between described turning axle and housing.
Seal groove and lip circle is had, for examining the static seal performance under different pressures between end cap and housing.Lip circle and Glais ring are housed between turning axle and housing, examine the motive seal performance of turning axle respectively.
Pressure regulation device primary responsibility provides required pressure source for testing table, is made up of hand increasing pressure pump and pipeline, and hand increasing pressure pump can the pressure of control system accurately.
The real-time pressure of data acquisition unit primary responsibility acquisition test system, motor speed and gyrofrequency.
When investigating static seal, between end cap 6 and housing 5, there are seal groove and lip circle, by the liquid medium pressurization in pressure regulation device 2 pairs of housings, each pressurization 0.5MPa, pressurize 30 minutes, whether real-time pressure shows pressure in real time by data acquisition module 3, observe pressure and decline, when investigating motive seal, the lip circle between turning axle and housing and Glais ring simulation is utilized to verify, 3MPa is forced into by the liquid medium in pressure regulation device 2 pairs of housings 5, afterwards rotary drive system 7 is powered, setting speed is 120rad/min, reciprocating rotating frequency 4Hz, driven by motor rotating shaft in rotary drive system 7 rotates, by pressure in data acquisition module 3 real time record housing, gyrofrequency and rotating shaft rotating speed, if pressure display numerical value is constant, be sealing good, with the sealing of this testing authentication rotating shaft under different reciprocating rotating frequency and moment of torsion.
By test, under different operating mode, the present invention can well static seal and the motive seal under water of simplation verification model device, meets design requirement.
The above know-why being specific embodiments of the invention and using, any based on the equivalent transformation on technical solution of the present invention basis, all belong within protection scope of the present invention.
