Description
Technical field
The utility model is related to the Parts of Compressor of refrigeration plant, more particularly to two kinds of blowdown Compressor Air Exhaust Valve Plates
Limiter.
Background technology
The suction of refrigeration compressor, exhaust valve plate are one of critical components in compressor, and it is direct control refrigeration system that it, which is acted on,
The conveying of refrigerant in system, the conveying of refrigerant is suction, exhaust valve plate open and close progress by compressor, is particularly existed
In exhaust valve plate opening process due in compressor casing pressure at expulsion it is higher, and the flow velocity of refrigerant is very fast, exhaust valve plate
The refrigeration oil of refrigerant produces higher temperature because of shock when producing shock with limiting plate makes refrigeration oil produce carbon fouling sometimes,
This carbon fouling is harder, is the pollutant in a kind of harmful compressor, if this harder carbon scaling fouling thing can not be arranged
Go out and remaining in compressor is easily caused the cylinder body of compressor to be pulled and make compressor in the cylinder body of air-breathing to compressor
Damage；On the other hand due to compressor in breathing process if some impurity in suction refrigeration system are also a kind of to compression
The harmful pollutant of machine, harmful pollutant of cylinder body can also be pulled to compressor formation by remaining in compressor cylinder body.
If one existing freezer compressor exhaust valve plate generates freezing oil carbon fouling when being hit with limiting plate when
As in the case of carbon fouling be difficult to be vented outside cylinder body, and easily flow into and cause compressor to produce scuffing of cylinder bore in the cylinder body of compressor to show
As and cause compressor damage, the utility model is exactly that the end of the limiting plate of air bleeding valve is processed into a small circular holes when freezing
Refrigerant has certain impulsive force, the carbon knot so formed under high-voltage high-speed when fry dried food ingredients has during carbon fouling due to exhaust
Dirt will be flushed in refrigeration system by refrigerant without remaining in the cylinder body of compressor.Same compressor is in breathing process
It is also possible to suck harmful impurity in system, if rushed in exhaust process by high speed and high pressure air-flow by tongue tongue
It is unlikely to damage compressor in the system of returning.
The refrigeration system of freezer compressor typically all carries out strict cleaning in production process, should not generally there is shadow
The impurity and pollutant of refrigeration performance are rung, but can occur mechanical wear unavoidably in refrigeration system running and produce some impurity
With other pollutants, also exhaust valve plate during opening and closing between valve plate and limiting plate high speed and high pressure collision and
The high temperature of generation makes the refrigeration oil in compressor occur harder carbon knot, and these impurity, pollutant and carbon fouling are to compressor cylinder
Body is particularly detrimental, it is easy to pull the cylinder body of compressor, causes compressor damage, and in the row of spacing plate of discharge valve block front end
When stomata position processing one has aperture, if having foreign-matter contamination and carbon fouling in system, it will by the air-flow band of refrigerant
In the cylinder body for being unlikely to flow to compressor into the system of compressor, the damage of compressor is so can be avoided, so as to carry
The high reliability of compressor.
