Abstract

The invention particularly relates to a vortex type air compressor which comprises an integral shell, wherein a compression chamber, a gas-oil separation device and an oil return pipe are adjacently arranged inside the shell and all arranged inside the compressor to form the air compressor with compact structure. The air compressor has the advantages of small size and good shock resistance effect and can meet the low-temperature working requirements since the oil return pipe is internally installed.

Description

Air compressor

Technical field

The invention belongs to bleed pressure and supply with the field, be specifically related to a kind of scroll type air compressor.

Background technique

In the bleed pressure supplier, usually oil air separation and return tube are split-type structurals, and volume is big, and anti seismic efficiency is poor, and can not satisfy the requirement of low-temperature working.

Summary of the invention

The purpose of this invention is to provide that a kind of volume is little, anti-seismic performance good and can satisfy the air compressor of low-temperature working requirement.

For achieving the above object, the present invention adopts following technological scheme: the present invention includes an integrally-built housing, adjacent pressing chamber, gas and oil separating plant, the return tube of being provided with in the inside of described housing.

As shown from the above technical solution, the three is arranged on compressor inside, forms a kind of air compressor of compact structure, and volume is little, anti seismic efficiency good, and return tube is built-in, can satisfy the requirement of low-temperature working.

Description of drawings

Fig. 1 is the structural drawing that air compressor of the present invention is connected with motor;

Fig. 2 is the structural representation of air compressor of the present invention.

Embodiment

As shown in Figure 2, the present invention includes an integrally-built housing, adjacent pressing chamber 10, gas and oil separating plant 20, the return tube 60 of being provided with in the inside of described housing.

The three is arranged on compressor inside, forms a kind of air compressor of compact structure, and volume is little, anti seismic efficiency good, and return tube is built-in, can satisfy the requirement of low-temperature working.

As shown in Figure 2, the inside of described pressing chamber 10 is provided with compressor 11, and compressor 11 links to each other with suction port 40, and as shown in Figure 1, the transmission shaft 50 of compressor 11 is connected with the rotating shaft of motor 30.

Described transmission shaft 50 is provided with external key or external splines, and the end cap of motor 30 is provided with internal key or internal spline, and described compressor 11 is connected with motor 30 with the engagement of internal key or internal spline by external key or external splines.

The shell of this device is provided with integral type fin type radiating fin, and the cooling fan (not marking among the figure) by motor 30 cools off, and described radiating fin is arranged at the vacant place of air compressor shell.

Compressor 11 adopts external key or external splines, directly link to each other with motor 30, simple in structure, concentricity easily guarantees, the air compressor shell adopts the heat radiation of integral type fin type, and good heat dissipation effect can directly utilize the cooling fan of motor 30 that air compressor is cooled off, need not add fan, reduce the volume and weight of air compressor.

As shown in Figure 2, described gas and oil separating plant 20 comprises high-pressure chamber 22 that is arranged at top and the oil storage storehouse 23 that is arranged at the bottom, described high-pressure chamber 22 and pressing chamber 10 communicate by the through hole on the next door that is arranged at both, described high-pressure chamber 22 and oil storage storehouse 23 communicate by the through hole on the dividing plate that is arranged at both, the top of high-pressure chamber 22 is provided with oil-gas separating filter element 21, oil-gas separating filter element 21 links to each other with air outlet 70, one of described return tube 60 terminates at the bottom in oil storage storehouse 23, and the other end links to each other with the bottom of pressing chamber 10 by a through hole.

Pressing chamber 10 also is provided with oil ga(u)ge, can observe what of oil mass in the pressing chamber 10 by oil ga(u)ge, oil storage storehouse 23, high-pressure chamber 22, transmission shaft 50, compressor 11, suction port 40, vernier 80, oil-gas separating filter element 21, air outlet 70, return tube 60 etc. all design at internal body, form a kind of air compressor of compact structure, user demand in light weight, as to satisfy low temperature and antidetonation, minimum operating temperature can reach-40 ℃, especially is suitable for the occasion of vehicular applications.

Described compressor 11 is a scroll compressor, and advantages such as that scroll compressor has is energy-efficient, noise is low, vibrations are little, durable in use, life-span length, pressurized air cleaning adopt scroll compressor, makes that the present invention is energy-conservation, noise is low, shelf life is long.

As shown in Figure 2, described suction port 40 and air outlet 70 are arranged at the same side of described housing, and suction port 40 and air outlet 70 are arranged at a side, are convenient to the installation of air inlet pipeline and outlet pipe.

It is 0.6 ~ 0.8Mpa that the present invention exports the bleed pressure scope, and 70 places connect different gas pressure sensors in the air outlet, can obtain the source of the gas of different pressures, and pressure maximum can reach 1.5Mpa.

The working principle of preferred embodiment of the present invention is described below in conjunction with Fig. 1, Fig. 2, motor 30 drives scroll compressor 11 work by transmission shaft 50, pressurized air, band is got lubricant oil and is lubricated and seals simultaneously, the oil-containing high-pressure air enters high-pressure chamber 22 from pressing chamber 10, the pressurized air that enters high-pressure chamber 22 carries out Oil-gas Separation by oil-gas separating filter element 21, cleaned air after the separation is discharged by air outlet 70, filter the remaining oil in back and be stored in the oil storage storehouse 23, get back to pressing chamber 10 through return tube 60 and use for 11 next times for scroll compressor.
