Description
Technical field
The present invention relates to a kind of natural gas supply sub-station compressor field, particularly relate to the gas compressing apparatus of this compressor.
Background technology
Natural gas is a kind of preferable automobile-used alternative energy source, and its application technology reaches its maturity through many decades development.It has cost
Low, high efficiency, pollution-free, use the features such as safe and convenient, the most day by day demonstrate powerful development potentiality.In recent years, along with
Country constantly promotes gas combustion automobile, and the quantity of Gas Filling Stations in Cities constantly rises.Natural gas compressor is as the pass of natural gas filling station
Button apparatus, its performance will directly affect the operation at full station.
The gas pressure change of natural gas supply sub-station source of the gas is relatively big, and this high compression ratio, the type of relatively low discharge capacity, with piston
Formula compressor is the most applicable.The piston compressor of natural gas filling station of the prior art generally contacts reciprocating compressor,
This compressor is mainly by fuselage, bent axle, connecting rod, piston, cylinder and suction, air bleeding valve, crosshead, slideway, piston rod with fill out
The compositions such as material letter；During compressor operation, motor band dynamic crankshaft rotates, and makes piston make by connecting rod, crosshead reciprocal
Motion.Bent axle rotates a circle, and reciprocating motion of the pistons once, realizes the process of air-breathing, compression, aerofluxus in succession in cylinder, the completeest
Become a cycle of operation.This compression function have enough be applicable to low pressure (including vacuum), pressure, high pressure and supertension, its efficiency
Higher than Rotary Compressor and speed mode compressor, the adiabatic efficiency of Large-scale Reciprocating Compressor is more than 80%, secondly, and aerofluxus
Weight range is relatively wide, also can keep higher efficiency under less capacity, and capacity fluctuated by pressure at expulsion affected the least.
In addition gas density is less notable on the impact of compressor performance, therefore the versatility of machine is good；But this compressor has following lacking
Point:
1, structure is more complicated, and consumable accessory is more, safeguards, overhauls and install the most cumbersome, rubs and weares and teares relatively big, piston and gas
Between cylinder, between piston rod and cylinder filler, all there is friction power loss, reduce the efficiency of unit, there is substantial amounts of consumable accessory,
Housing Starts is low, maintenance cost is high；
2, it is integrated attachment structure due to whole gas compressing apparatus (bent axle, connecting rod, piston and cross are first-class), causes reciprocal
Inertia force relatively big, therefore rotating speed is relatively low；When the bigger capacity of needs, its body is huge, and heaviness also needs large foundation, therefore,
When capacity is bigger, the volume that piston compressor is corresponding is bigger；
3, aerofluxus is discontinuous, causes gas, produces gas resonance, can cause the damage of pipe network or parts time serious.
Summary of the invention
Present invention aim at providing a kind of natural gas supply sub-station compressor, be used for solving structure complexity, inertia in prior art
