Abstract
A method to judge whether the key character of compressor is qualified by exhausting volume in limited time has the characteristics: A. the testing instruments: piston and air cylinder inside; B preliminary work : decided by the work of standard compressor: the height h of piston jacked by air in unit time t; C. testing steps and judging method: observe the distance of piston jacked by air in air cylinder in unit time t and when the distance is equal to or surplus the height h, the work compression rate or refrigerating capacity of the compressor is qualified; when the distance is smaller then h, it is not qualified.
Description
Technical field:
The present invention relates to compressor characteristics quality inspection technology.
Background technique:
Compressor is modal mechanical classification, and its work compression ratio is high more, and so, its compression property is just good more.Yet, whether the quality that the method that the actual conditions that the service behaviour detection of compressor was often adopted 1: 1 detects is differentiated it is qualified, for example: the compressor of refrigeration purposes, be the refrigeration system that it is placed actual applying working condition, by the test result of its refrigerating capacity being judged whether it is up-to-standard.Control the compressor of having decided the refrigerator purposes among the GB GB9098----88 and test the standard of judging that whether qualified it is by it forms refrigerating capacity in refrigeration system size.
If whether the compressor of producing in factory mass all adopts national standard method to differentiate compressor as its essential items for inspection embodiment qualified, obviously is difficult.If can adopt with GB GB9098----88 in the embodiment formulated the simple and direct embodiment of equivalent relation is arranged, it is examined the project implementation scheme as compressor function character, so, the quality inspection project of reflection compressor cooling flow characteristic has been created condition with regard to the essential items for inspection that can be used as every compressor.
Summary of the invention:
The present invention's purpose: propose a kind of simple and direct embodiment that can reflect compressor key function characteristic quality inspection project fast, for its essential items for inspection that become every compressor create conditions.
In order to realize goal of the invention, intend adopting following technology:
Allow its work compression ratio or refrigerating capacity just reach relevant GB required standard compressor, and the exhaust volume in the unit time of measuring with its is a critical data, perhaps, to discharge the needed time of certain gas volume is critical data, whether the relevant key characteristic of judging other tested compressor fast is qualified, promptly whether reaches the requirement of GB.
Characteristics of the present invention:
Because the present invention can require to set up equivalent relation with GB, these essential items for inspection that just make it possible to reflect that the quality inspection project of key characteristic of compressor (work compression ratio or refrigerating capacity) can become every compressor product have been created condition.
Description of drawings:
Figure has illustrated one embodiment of the present of invention.
1: inflator; 2: the gas overflow hole; 3: piston; 4: pneumatic tube (flexibility); 5: outlet pipe; 6: tested compressor; 7: suction tude; H: piston is by the height of gas jack-up (position in gas overflow hole).
Embodiment:
A. the test instrument equipment that adopts of the present invention:
Inside is provided with the inflator 1 of piston 3, and inflator 1 transparent toughened glass of preferably drawing materials is convenient to observe the position of piston 3.
B. preparatory work of the present invention:
Start work by standard compression machine (work compression ratio or refrigerating capacity just reach the requirement of relevant GB) is determined: unit time t inner carrier 3 is by the height h of gas jack-up, after this, because the existence in gas overflow hole 2, piston 3 can not continue to be risen by gas.
C. testing procedure of the present invention and determination methods:
A, with the outlet pipe 5 of tested compressor 6 by pneumatic tube 4, link to each other with the bottom of inflator 1, allow the suction tude 7 of tested compressor 5 be exposed to airspace.
B, energising start tested compressor 6.
C, observe unit time t inner carrier 3 in inflator 1 by the situation of gas jack-up: when piston 3 had been less than or equal to have crossed height h in time period of unit time t, then: the work compression ratio or the refrigerating capacity of tested compressor 6 were qualified; When piston 3 just arrived height h in more than the time period of unit time t, then: the work compression ratio or the refrigerating capacity of tested compressor 6 were defective.
Claims (2)
