Description
Technical field
The invention belongs to testing apparatus technical field, particularly relate to a kind of life test apparatus of compressor valve plate.
Background technique
The working life of component of machine is one of main performance requirements of machinery.At present, the test in Compressor Air Exhaust Valve Plate working life does not have special testing installation, normally adopts cam or eccentric structure that valve block is produced and moves up and down to test.As shown in Figure 1, for in prior art for the equipment of test compression machine valve block situation in working life, one end of valve block 10 is fixed by punch holder 100, die holder 101 and fastening screw trip bolt 102, the other end (free end) of valve block 10 is close on eccentric wheel 103, by the rotary actuation of eccentric wheel 103, with the cycle Bending Deformation of moving valve plate 10, thus the reliability of service life of test valve block.
But under the actual working state of compressor, valve block can periodically impact valve block baffle plate and pat relief opening under the effect of high pressure gas, the test method adopting eccentric wheel to make valve block produce Cyclic flexion deformation can not be tested in the impact of actual working state and beating process simulation valve block, and therefore test result is often not accurate enough.
Summary of the invention
The object of this invention is to provide and a kind ofly to the impact of valve block and process simulation can be patted, thus detect the testing apparatus in valve block life-span more accurately.
To achieve these goals, the present invention takes following technical solution:
Compressor valve plate life test apparatus, comprising:
Stationary platen, described stationary platen is provided with exhaust port;
Be arranged at the valve block clamping plate on described stationary platen, for clamping valve block, the free end of described valve block fits on exhaust port;
Be arranged at the electromagnet stent on described stationary platen;
The electromagnet above described valve block free end is arranged at by described electromagnet stent.
Further, the angle between the bottom surface of described electromagnet and horizontal plane is 0 ~ 20 °.
Further, the angle between the bottom surface of described electromagnet and horizontal plane is 5 ~ 15 °.
Further, described electromagnet arranges radiating subassembly.
Further, described radiating subassembly comprises heat-dissipating fan, radiating fin and lid, the dividing plate that described radiating fin is installed on described lid is positioned at below described dividing plate, described dividing plate is provided with vent hole, described heat-dissipating fan to be arranged in described lid top and to be positioned at above described dividing plate; Described radiating fin contacts with described electromagnet.
The present invention controls the motion of valve block by the electromagnet arranging periodically power on/off, absorption or release valve block in the process of magnet switching electricity, thus analog compression machine work time valve block motion state, overcoming prior art adopts eccentric wheel to make the test method of valve block generation Cyclic flexion deformation to valve block in the impact of actual working state and the defect of patting process simulation test, can not improve the validity of valve block life test result.

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in more detail.
Embodiment
As shown in Figures 2 and 3, the valve block life test apparatus of the present embodiment comprises stationary platen 1, valve block clamping plate 2, electromagnet 3, electromagnet stent 4.Valve block clamping plate 2 are arranged on stationary platen 1 by screw 2a, and valve block clamping plate 2 are for fixing valve block 10.Stationary platen 1 is processed with relief opening 1a.After one end of valve block 10 is fixing by valve block clamping plate 2, the other end (i.e. free end) of nature lower valve 10 fits on relief opening 1a.Electromagnet stent 4 is fixed by screw and stationary platen 1, and electromagnet 3 is installed on stationary platen 1 by electromagnet stent 4, and electromagnet 3 is positioned at the top of valve block 10 free end.Angle between the bottom surface of electromagnet 3 and horizontal plane can be set to 0 ~ 20 °, is preferably designed to 5 ~ 15 °.
As the preferred technological scheme of the present invention, electromagnet 3 arranges radiating subassembly 5, for giving electromagnet 3 cooling.Radiating subassembly 5 comprises heat-dissipating fan 5-1, radiating fin 5-2 and lid 5-3.Radiating fin 5-2 is installed on the dividing plate 5-3a of lid 5-3, and radiating fin 5-2 is positioned at below dividing plate 5-3a.Dividing plate 5-3a is processed with some spaced apart vent hole 5-3b.Heat-dissipating fan 5-1 is arranged in lid 5-3 top, and heat-dissipating fan 5-1 is positioned at above dividing plate 5-3a.Lid 5-3 is buckled on electromagnet stent 4 by the mode of buckle, radiating fin 5-2 is enclosed within electromagnet 3 peripheral simultaneously, radiating fin 5-2 is contacted with electromagnet 3, helps electromagnet 3 to dispel the heat.During heat-dissipating fan 5-1 work, dry toward radiating fin 5-2, thus reduce the temperature of electromagnet 3, to avoid, electromagnet 3 temperature is too high to be burnt out.Electromagnet 3 and heat-dissipating fan 5-1 are by external power source.The radiating fin that the radiating subassembly of electromagnet also can adopt separately heat-dissipating fan or contact with electromagnet.
Below in conjunction with Fig. 4 and Fig. 5, the test process of testing apparatus of the present invention is described further.
As shown in Figure 4, when electromagnet 3 is not energized, in the raw, the free end of nature lower valve 10 fits on the relief opening 1a of stationary platen 1 valve block 10, the state that during work of analog compression machine, relief opening is not vented, relief opening is closed;
As shown in Figure 5, after electromagnet 3 is energized, the free end of valve block 10 is held by electromagnet 3, makes valve block 10 upwards be attached on electromagnet 3 bottom surface, and during the work of analog compression machine, relief opening discharges the state of pressurized gas, Exhaust Open;
The landing of valve block 10 is controlled by controlling electromagnet 3, namely when electromagnet 3 is energized, valve block 10 is held by electromagnet 3, during electromagnet 3 power-off, valve block 10 is released, and then pats on relief opening 1a, during test, repeat above process, simulation valve block dash valve sheet baffle plate and beating relief opening were tested the valve block life-span.
The present invention is by arranging electromagnet, and need according to design the power on/off frequency passing to setting to electromagnet, electromagnet will adsorb valve block by the frequency discontinuity of setting, thus make valve block by the frequency discontinuity Ground shock waves electromagnet of setting and pat relief opening, real simulation goes out impact and the beating process of compressor actual working state lower valve, thus detects the reliability of service life of valve block more accurately.
Above embodiment is only in order to illustrate that technological scheme of the present invention is not intended to limit, although with reference to above-described embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that, still can modify to the specific embodiment of the present invention or equivalent replacement, as electromagnet shape except can be cylindrical except, also can be square or other suitable shapes, the structure of radiating fin and shape be also with the shape respective change of electromagnet.Therefore, do not depart from any amendment of spirit and scope of the invention or equivalent replacement, it all should be encompassed in the scope of technical solution of the present invention.
