Description
Technical field
The invention belongs to freezer compressor technical field of performance test, and in particular to a kind of freezer compressor performance test is set
Standby check device.
Background technology
Compressor is the heart of refrigeration system, and it sucks the refrigerant gas of low-temp low-pressure from air intake duct, is transported by motor
Turn after being compressed with piston to it, the refrigerant gas of HTHP discharged to blast pipe, power is provided for kind of refrigeration cycle,
So as to realize the kind of refrigeration cycle of compression → condensation → expansion → evaporation (heat absorption).Compressor it is general by housing, motor, cylinder body,
Piston, control device (starter and thermal protector) and cooling system composition.The type of cooling has two kinds of oil cooling and natural cooling.One
As domestic refrigerator compressor be that power supply is used as using single-phase alternating current.
Compressor is produced in a pipeline fashion.Cylinder body, piston are produced in engineering shop's (including casting) (to turn
Axle), valve block, connecting rod, bent axle, the parts such as end cap；Rotor, stator are assembled in motor workshop；Shell is produced in press workshop
Body etc..Then assembled in assembly shop, welded, cleaning, drying, most afterwards through examining qualified packaging to dispatch from the factory.At present, it is mostly raw
The producer of compressor is produced after the completion of production and assembly compressor, due to being limited by plant produced condition, the work of compressor is produced
Factory tends not to detect the performance of compressor, or is only limitted to the field investigation to its mechanical performance, and this allows for pressure
There is certain risk in reliable performance in actual applications in contracting machine.
Therefore, freezer compressor manufacturer, increasingly payes attention to the exfactory inspection work of freezer compressor, to ensure refrigerator pressure
Contracting machine dispatches from the factory acceptable performance, product competition type is improved, while also increasing economic efficiency.Wherein, with the operation freezer compressor that is powered,
To test based on its combination property.Carried out because freezer compressor is powered in performance test process, it is necessary to be accurately positioned refrigerator pressure
Contracting machine, the process that follow-up freezer compressor energization performance test could be carried out；Occur in position fixing process freezer compressor by
Snap-off-distance is produced in effect of inertia, causes its positioning inaccurate；It is therefore, a kind of universal in order to eliminate its snap-off-distance
Check device is the emphasis and focus in freezer compressor performance test field.
The content of the invention
The present invention is in order to overcome the above-mentioned deficiencies of the prior art there is provided a kind of freezer compressor performance test apparatus with stopping
Return device, the present apparatus is simple in construction, and governing speed is fast, it is adaptable to which various types of freezer compressor, versatility is very high
And manufacturing cost is low, it can preferably realize that freezer compressor is accurately positioned requirement before energization performance test.
To achieve the above object, present invention employs following technical scheme：
A kind of freezer compressor performance test apparatus check device, the check device includes non-return mechanism and non-return machine
Structure connects and supported the bracket institution for coordinating non-return mechanism to limit freezer compressor resilience.
It is preferred that, the non-return mechanism includes U-shaped seat, the non-return block being rotatably fixed on U-shaped seat, the non-return block
The height that free position is originated in rotation process is higher than the top plan of U-shaped seat；It is embedding between the non-return block and U-shaped seat to be connected with
Elastic mechanism.
Further, cushion block is installed close to bottom end in the U-shaped seat, the U-shaped proximal portion that seats against is equipped with pin
