Abstract
The present invention relates to a method for judging whether the key characteristic of a compressor is qualified or not by limiting the consumption time of gas exhaust volume. The present invention is characterized in that: a, a gas cylinder (1) in which a piston (3) is arranged is used as a test instrument and test equipment; in the preparation work, the height (h) of the piston (3) jacked by gas in unit time t is determined by the starting work of a standard compressor; in the test steps and the judgment method, the condition that the piston (3) is jacked by gas in the gas cylinder (1) in the unit time t after the compressor (6) is started is observed, when the piston (3) exceeds the height (h) in the time period which is less than or equal to the unit time t, the work compression ratio or the refrigerating capacity of the measured compressor (6) is qualified; when the piston (3) reaches the height (h) in the time period more than the unit time t, the work compression ratio or the refrigerating capacity of the measured compressor (6) is unqualified.
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.GB GB9098---the compressor that the refrigerator purposes has been decided in restraining in 88 is tested 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 and GB GB9098---the embodiment of formulating in 88 has the simple and direct embodiment of equivalent relation, 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:
A. the test instrument equipment of Cai Yonging:
Inside is provided with the inflator of piston, and this inflator adopts transparent toughened glass to make;
B. preparatory work of the present invention:
Start work by the standard compression machine is determined: unit time t inner carrier is by the height of gas jack-up;
C. testing procedure and determination methods:
A, with the outlet pipe of tested compressor by pneumatic tube, link to each other with the bottom of inflator, allow the suction tude of tested compressor be exposed to airspace;
B, energising start tested compressor;
C, observe piston in inflator by the situation of gas jack-up:
When piston had been less than or equal to have crossed described height in time period of unit time t, then: the work compression ratio or the refrigerating capacity of tested compressor were qualified;
When piston just arrives described height in more than the time period of unit time t, then: the work compression ratio or the refrigerating capacity of tested compressor are defective.
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 this inflator 1 adopts transparent toughened glass 2 (being convenient to observe piston 3 positions) to make.
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 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.
Obviously, key of the present invention is:
Allow work compression ratio or refrigerating capacity just reach relevant GB required standard compressor, and be critical data to discharge the needed time of certain gas volume, whether the relevant key characteristic of judging other tested compressor fast is qualified, promptly whether reaches the requirement of GB.
