Abstract
The utility model discloses a full oil-less compressor with crosshead, belonging to a reciprocating piston compressor. The aim of the utility model is to provide a new full oil-less compressor with crosshead and piston-rod. The utility model is characterized in that a crosshead, a piston-rod, a packing sealing device, and a friction support bushing are added to the utility model compared with the ordinary full oil-less compressor. The utility model has all the advantages that the full oil-less compressor has, improves the sealing performance of the compressor, makes the whole machine not leak, and widens the application range of the full oil-less technology. The single row of the utility model can achieve a one-level compression to a three-level compression, particularly be suitable for small displacement of hydrogen, nitrogen, oxygen, liquid gas, natural gas and other special gases, the compression of the high voltage, the medium voltage and the low voltage, and the transportation of the high voltage, the medium voltage and the low voltage.
Description
Technical field:
The utility model belongs to Reciprocting piston compressor.
Background technique:
Obtain than widespread usage in the microminiature air compressor completely without oil tech.What is called all adopts the rolling bearings that are lubricated with lubricating grease completely without crank shaft, the connecting rod that oil is actually compressor, and complete machine lubricating oil filling in addition is lubricated.But the defective of this type is no crosshead body, piston-rodless, nothing fills out the letter seal arrangement.Compresser cylinder relies on piston ring fully and seals, thereby sealing is poor, only is suitable for boosting of low-pressure air, and is unsuitable for the compression conveying of special gas.
Summary of the invention:
The purpose of this utility model is to provide a kind of compressor new architecture completely without oil with crosshead body.The utility model is realized with following mode: a kind of completely without oil band crosshead body compressor, it has base 2, fuselage 3 is installed on base 2, crank shaft 4 and its crank throw coupler link 5 major parts are housed in fuselage 3, the end in addition of crank shaft 4 connects flywheel coupling 1, this flywheel coupling 1 is positioned at outside the fuselage 3, and crank shaft 4 connecting rods 5 are the rolling bearing of band lubricating grease; The microcephaly who it is characterized in that connecting rod 5 connects crosshead body 6 connection piston rod 8 again, and the piston body on this piston rod 8 is in cylinder 10, and piston rod 8 is to fill out letter seal arrangement 9 with the sealing of cylinder 10, and crosshead body 6 is housed on connecting rod 5, and friction supporting sleeve 7 is equipped with on these crosshead body 6 surfaces.This completely without oil band crosshead compressor, it is that microcephaly with connecting rod 5 connects with a crosshead body 6, and rotatablely moving of crank shaft 4 become the linear reciprocating motion of crosshead body 6, drives piston rods 8 by crosshead body 6 again and moves reciprocatingly.The friction supporting sleeve 7 of the good self-lubricating property of tool is equipped with on the crosshead body surface of this crosshead body 6, and piston rod 8 adopts with the sealing of cylinder 10 and fills out letter seal arrangement 9.The utility model possesses whole advantages of oil-free compressor, has increased the sealability of compressor greatly, can realize that complete machine does not have to leak, and has widened the application area completely without oil tech greatly.Single-rowly realize one-level to three grade compression, be specially adapted to the little discharge capacities of special gas such as hydrogen, nitrogen, oxygen, liquid gas, rock gas, the compression of high, medium and low voltage, conveying.
Description of drawings:
Fig. 1-Fig. 2 is a structural representation of the present utility model.Wherein Fig. 1 is embodiment 1: hydrogen three stage compressor structural representation; Fig. 2 is embodiment 2: nitrogen single stage compressor structural representation.
Embodiment:
Now the utility model is described in further detail in conjunction with the accompanying drawings.
With reference to Fig. 1, embodiment 1: the hydrogen three stage compressor; With reference to Fig. 2, embodiment 2: the nitrogen single stage compressor; The band crosshead body 6 that the utility model is designed, band piston rod 8 completely without oily new architecture, its structure is crank shaft 4, the connecting rod 5 that keeps completely without oil, has increased crosshead body 6, piston rod 8, and has filled out letter seal arrangement 9.For realizing the oil-free lubrication of crosshead body 6, adorn a friction supporting sleeve 7 that self-lubricating property is good on crosshead body 6 surfaces, do not need to be lubricated in addition when making it in slideway to-and-fro motion.In actual motion, as long as be no more than the PV value allowable (product of specific pressure and crosshead linear velocity, the MPA.M/S of unit) of supporting sleeve material, 7 wearing and tearing of friction supporting sleeve are minimum, can guarantee long-term good operation.
