Background technology
Refrigeration compressor is the important component of the electric refrigerator equipment such as air-conditioning, refrigerator.Wherein piston connecting rod type refrigerant compression
Machine is current most widely used compressor.At present piston connecting rod type refrigeration compressor moved by piston in cylinder cylinder holes into
Discharged after row gas compression, when piston movement is to cylinder holes tail end, the clearance of piston end surface to valve block, have influence on each piston movement
When discharge the amount of gas, influence the refrigerating efficiency of compressor.When cylinder head clearance amount is big, compressor horsepower is low, and refrigerating capacity is low, refrigeration
Efficiency is low；Cylinder head clearance amount hour, compressor horsepower is high, and refrigerating capacity is high, and refrigerating efficiency is low.Therefore refrigerant compression is confidential by cylinder head
Stand off is controlled in certain scope.The control in refrigeration compressor assembling process to stand off is measured by bottom clearance at present
After place corresponding pad, pass through the indirect control stand off such as piston projection amount, spacer thickness.Reality after having been assembled to compressor
Border stand off, in the case where not disassembling, without detection means, the compressor cooling caused by cylinder head clearance error can not be avoided
Efficiency fluctuation.
Utility model content
Technical problem to be solved in the utility model is to provide one kind can in the case where not disassembling and accurately detected
The refrigeration compressor cylinder head clearance amount detection systems of the actual stand off gone out after compressor has assembled.
The utility model solves refrigeration compressor cylinder head clearance amount detection systems used by its technical problem：Including work
Plug, cylinder, cylinder cap, vaccum-pumping equipment, vacuum inspective meter and the pad arranged successively from cylinder to cylinder cap direction, inlet valve
Piece, valve plate, exhaust valve plate, gland shim, the piston are located in cylinder, and discharge chamber and suction muffler are provided with the cylinder cap,
The vaccum-pumping equipment connects with discharge chamber, and the vacuum inspective meter connects with discharge chamber.
It is further, in addition to controller and display, the signal input part of the vacuum inspective meter and controller
Telecommunication connects, and the display connects with the signal output part telecommunication of controller.
It is further that wireless signal output module is provided with the vacuum inspective meter, is set on the controller
There is reception of wireless signals module.
The beneficial effects of the utility model are：The ingenious architectural feature using piston connecting rod type refrigeration compressor of the application,
By the way of vacuumizing, make suction airflow and vacuumize air-flow formation balance, keep the stable vacuum values for being easy to measurement.It is logical
Cross and measure the vacuum values to obtain accurate piston and suction valve chip stand off.The application need not tear the compressor assembled open
Open, measurement is quick, convenient, and can accurately measure the piston after assembling and suction valve chip stand off, can be more accurately
Control clearance is so as to effectively avoid compressor cooling efficiency fluctuation caused by cylinder head clearance error.
Brief description of the drawings
Fig. 1 is the structural representation of the application；
Parts, position and numbering in figure：Piston 1, cylinder 2, pad 3, suction valve chip 4, valve plate 5, exhaust valve plate 6, cylinder
Lid 7, discharge chamber 8, suction muffler 9, gland shim 10.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, refrigeration compressor cylinder head clearance amount detection systems of the present utility model：Including piston 1, cylinder 2, cylinder
Lid 7, vaccum-pumping equipment, vacuum inspective meter and the pad 3 arranged successively from cylinder 2 to the direction of cylinder cap 7, suction valve chip 4, valve plate
5th, exhaust valve plate 6, gland shim 10, the piston 1 are located in cylinder 2, and discharge chamber 8 and suction muffler are provided with the cylinder cap 7
9, the vaccum-pumping equipment connects with discharge chamber 8, and the vacuum inspective meter connects with discharge chamber 8.The wherein connection of discharge chamber 8 system
The exhaust end of cold compressor, suction muffler 9 connect the suction end of refrigeration compressor.
When practical vaccum-pumping equipment vacuumizes from exhaust end, discharge chamber 8 forms negative pressure, and exhaust valve plate 6 is opened necessarily by suction
Angle, gas siphons away out of cylinder body cylinder holes and forms negative pressure, and suction valve chip 4 opens certain angle by suction, and gas is inhaled from inlet chamber
Enter.When suction airflow is with air-flow formation balance is vacuumized, vacuum value stabilization.
When suction airflow is with air-flow formation balance is vacuumized, under vacuum values stable case, when piston 1 is run to top dead centre
During, the end face of piston 1 can prop up the suction valve chip 4 of opening, and piston 1 arrives the stand off of suction valve chip 4, determines piston 1
The angle that suction valve chip 4 opens in top dead centre.Vacuum value corresponding to different opening angles be it is certain, both piston 1 with
The stand off of suction valve chip 4 is corresponding with vacuum values.Actual stand off is measured according to the big I of vacuum values.
Also including controller and display, the signal input part telecommunication of the vacuum inspective meter and controller connects,
The display connects with the signal output part telecommunication of controller.The vacuum values that vacuum inspective meter detects can pass
Controller is given, controller sends numerical value to display again, and vacuum values are directly displayed into tester by display.
Program can also be write according to vacuum values and the corresponding relation of refrigeration compressor cylinder head clearance, allow controller to turn vacuum
Directly displayed again by display after changing clearance amount into.
Wireless signal output module is provided with vacuum inspective meter, reception of wireless signals mould is provided with the controller
Block.Using transmission of wireless signals mode, signal conveying is not influenceed by line, can be direct by a large amount of testing results for detecting workshop
Management system is imported to be handled.
The ingenious architectural feature using the link-type refrigeration compressor of piston 1 of the application, by the way of vacuumizing, makes suction
Air-flow forms balance with air-flow is vacuumized, and keeps the stable vacuum values for being easy to measurement.Standard is obtained by measuring the vacuum values
True piston 1 and the stand off of suction valve chip 4.The application need not take the compressor assembled apart, and measurement is quick, convenient, and
And the piston 1 after assembling and the stand off of suction valve chip 4 can be accurately measured, clearance can be more accurately controlled so as to effectively keep away
Compressor cooling efficiency fluctuation caused by exempting from cylinder head clearance error.
Wireless signal output module is provided with the vacuum inspective meter, being provided with wireless signal on the controller connects
Receive module.Using wireless signal transceiver module, it is possible to achieve the long-distance transmissions of detected value, facilitate the fast of batch detection data
Fast typing.
