Between increase reinforcing rib 93, guarantee the intensity of entire cylinder body, ultimately form with air cavity package air cavity wall structure.Work as compressor operating
When, the charge air flow of low temperature enters inlet chamber 92 from cylinder air inlet 91 first, and is full of inlet chamber 92, the air inlet gas of low temperature
Stream package cylinder wall 95, exchanges heat, the frictional heat of cylinder wall 95 is conducted to the charge air flow of low temperature, i.e. the air inlet gas of low temperature
Stream is instead of cooling water.It under gas cylinder working condition, is neither water-cooled, can also reach the operating condition for having the cooling cylinder of water.
The working principle of the high revolving speed compressor set of reciprocating-piston in the present embodiment are as follows:
High revolving speed main motor driving compressor crank shaft rotation, by connecting rod, crosshead, is converted into cross for the rotary motion of crankshaft
The reciprocating motion of head, crosshead band piston move back and forth in cylinder, and the dielectric gas in piston compression cylinder makes to press
Power increases, and achievees the purpose that gas boosting.
Dielectric gas is entered in air inlet buffer by being connected to the pipeline of air inlet buffer, enters back into cylinder intake
Chamber enters cylinder interior by the intake valve between inlet chamber and compression chamber.Gas is after piston compresses, pressure rise
Temperature also increases, and closes intake valve, opens the exhaust valve between outlet chamber and compression chamber, and pressure high temperature hot gas passes through
Exhaust valve enters inblock cylinder air cavity, then in exhausting buffer, enters aerial cooler by pipeline.Pressure high temperature hot gas
It enters in separator after cooling, after the liquid for isolating condensation, medium gas drain separator enters downstream.Work as compression
When machine is multi-stage compression, gas enters the air inlet buffer of next stage, repeats the above process after separator discharge.
High temperature grease in body oil sump is sucked out oil pump (such as spindle nose pump), enters oil cooler after pressurization discharge
(air-cooled form) enters after supercooling and arrives oil strainer, passes through pipeline after filtering out impurity, enters compressor and respectively lubricate
Point.Wherein lubricating oil is branched into from total fuel feed pump to each main bearing shell all the way, and lubricating oil flows through main bearing shell, for main bearing shell profit
It is sliding, wash away the fines that friction generates and take away the heat that main bearing shell friction generates, oil between main bearing shell and crankshaft between clearance flow
Out.Another way lubricating oil is branched into from fuel feeding general pipeline to each crosshead crawler shoe oil-feed port, and a part oil is after crawler shoe lubricates
It is discharged from gap, another part oil oil circuit built-in from crawler shoe enters crosshead body and crosshead pin matching part, is ten
Prefix pin lubrication.A portion oil is to be discharged after crosshead pin lubrication from gap, and another part is built-in from crosshead pin
Oil circuit enters small end of connecting rod watt, enters major part watt for oil circuit built-in from gonnecting rod body again after microcephaly watt lubrication, is finally
Major part watt is discharged after having lubricated from gap.The hot oil being finally discharged from each lubricant housings gap, is pooled to body oil sump bottom.
Lubricating oil is discharged from oil syringe, and by filter, the note of each cylinder, filler is entered by stainless steel fuel feed pump
Hydraulic fluid port.
The high revolving speed compressor set of the present embodiment is to eliminate the cooling water of conventional compact unit entirely without water-cooled compressor group
The dielectric gas of system, the high pressure-temperature being discharged from cylinder is cooled down using aerial cooler；Using anhydrous air-cooled structure cylinder,
I.e. with the structure of inlet chamber package cylinder wall, inlet chamber is filled up in the air inlet (general 40 degree of medium gas intake air temperature) of low temperature, with gas
Casing wall exchanges heat, and the frictional heat that piston packing ring is generated with cylinder wall is taken away.Filler uses Patent No.
ZL201520071820.X, entitled " a kind of anhydrous cooled stuffing-box for high revolving speed reciprocating compressor "；Movement mechanism
Lubricating oil in lubricating oil system is cooling using aerial cooler；Main motor is cooled down using the air-cooled type of cooling.
