Description
Technical field
The present invention relates to technical field of refrigeration compressors, specifically a kind of for arranging refrigerant on reciprocating compressor
Go out the exhaust system of shell.
Background technology
The movement of compressor piston makes inner pressure of air cylinder change, so as to cause the opening and closing of suction valve chip.
When piston is moved to cylinder head, the pressure in cylinder can increase；When the pressure in cylinder is more than the pressure in shell, inhale
Air valve is closed；When the pressure in cylinder continues growing and is more than the pressure in discharge chamber, air bleeding valve is opened, and refrigerant enters gas
High pressure chest in cylinder cap enters back into interior comb subsequently into the discharge chamber on crankcase, finally enters the exhaust pipe row of compressor
Go out except compressor housing.High pressure chest of the refrigerant of high temperature and pressure out of cylinder head, into the discharge chamber on crankcase this
The operating path of section gas has prodigious relationship with compressor air-discharging pulsation.In addition the position of throttle orifice is also to compressor
Exhaust gas pulses have prodigious relationship.Since the structure of the exhaust system of existing crankcase is more complicated, crankcase casting cost ratio
It is higher, while because that can not arrange throttle orifice in the grate flow channel of existing crankcase, thus exhaust gas pulses are bigger.
Invention content
Technical problem to be solved by the present invention lies in a kind of exhaust gas pulses that can effectively reduce compressor are proposed, it is implemented as
This lower exhaust system for reciprocating compressor.
In order to solve the above technical problems, a kind of exhaust system for reciprocating compressor of the invention include crankcase, cylinder,
Cylinder head and interior comb, are equipped with high pressure chest in the cylinder head, the crankcase be equipped with first row air cavity, second row air cavity,
Third discharge chamber and the first cushion chamber, between the high pressure chest and the first row air cavity in the cylinder head, described first
It is respectively equipped with through-hole between discharge chamber and the second row air cavity, between the third discharge chamber and first cushion chamber, institute
It states and is connected to by connecting tube between second row air cavity and the third discharge chamber, the interior comb and the third discharge chamber phase
Even.
Above-mentioned a kind of exhaust system for reciprocating compressor, between the first row air cavity and the second row air cavity
The through-hole is throttle orifice.
For the present invention as a result of above-mentioned technical pattern, it has given full play to the effect of four exhaust cavitys on crankcase,
The exhaust gas pulses of compressor are minimized.Meanwhile without increasing too many part when implementation, the connection by cavity of arranging is suitable
The setting of sequence and throttle orifice, you can reduce exhaust gas pulses, application cost is relatively low.

Specific implementation mode
In order to obtain preferable exhaust system, the present invention devises five kinds of exhaust system schemes, lists possible exhaust line
The location arrangements of diameter and throttle orifice carry out analogue simulation and experiment test, with the preferable exhaust system scheme of determination so that
Exhaust gas pulses are minimum.
Such as Fig. 1, exhaust system scheme one includes cylinder 1k, cylinder head 3, first row air cavity 1a, second row air cavity 1b, connection
Pipe 4, third discharge chamber 1c, the first cushion chamber 1d and interior comb 5.The high temperature and high pressure gas through overcompression initially enters in cylinder 1k
High pressure chest 3a in cylinder head 3, then by being connected to the through-hole 1e of first row air cavity 1a, into first row air cavity 1a；Then lead to
The through-hole 1g for crossing connection second row air cavity 1b, into second row air cavity 1b；Then by connecting tube 4, into third discharge chamber 1c,
Part of refrigerant enters interior comb 5, and part of refrigerant enters the through-hole 1h of the first cushion chamber 1d of connection, finally returns the
Three discharge chamber 1c, enter back into interior comb 5.
As shown in Fig. 2, exhaust system scheme two includes cylinder 1k, cylinder head 3, high pressure chest 3a, connection first row air cavity 1a
Through-hole 1e, first row air cavity 1a, the through-hole 1g of connection second row air cavity 1b, second row air cavity 1b, connecting tube 4, third exhaust
Chamber 1c, through-hole 1h, the first cushion chamber 1d and the interior comb 5 for being connected to the first cushion chamber 1d, the high temperature through overcompression is high in cylinder 1k
Body of calming the anger initially enters the high pressure chest 3a in cylinder head 3, then by being connected to the through-hole 1e of first row air cavity 1a, into first row
Air cavity 1a；Then by being connected to the through-hole 1g of second row air cavity 1b, into second row air cavity 1b（Through-hole 1g is throttle orifice, is passed through
Throttling action is played in reduced bore, reduces exhaust gas pulses）；Then by connecting tube 4, into third discharge chamber 1c, part system
