Abstract

A low noise and high efficiency swirl air compressor is provided. A swirl compressor is equipped in conventional air compressors, and an oil deliver pipe is equipped to conduct lubricant in a gasholder through an electromagnetic valve and a pressure regulating valve, the lubricant is used to lubricate and cool and seal swirl blades.

Description

Scroll type air compressor

The utility model belongs to the air compressor technical field.

At present, conventional air compressor generally is piston type, rotary vane type, screw type etc., and there are shortcomings such as noise is big, efficient is low, complex structure, the huge heaviness of body, cost height in these conventional air compressors.And Whirl type compressor usedly can't apply because there being the problem of lubricated, sealing and cooling in air compression.

The purpose of this utility model provides a kind of scroll type air compressor.It has overcome the shortcoming of conventional air compressor, has solved problem lubricated, that seal and cool off again, has more advantages such as noise is little, efficient is high, simple structure, volume is little, cost is low, the life-span is long.

The purpose of this utility model is achieved in that motor passes through elastic coupling, and transmission of power is made its running to scroll type air compressor, with air compression in gas holder.Lubricant oil in the gas holder is because the effect of pressure in the gas holder, by pipeline through solenoid valve and pressure regulator valve, enter scroll type air compressor simultaneously by suction port and air mixing, be pressed into the circulation that so goes round and begins again in the gas holder simultaneously with air, thereby play purpose lubricated, that seal and cool off the scroll type air compressor turbine blade.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1, be the schematic representation of scroll type air compressor:

Fig. 2, be scroll type air compressor with belt, belt pulley and motor connected diagram:

Fig. 3, be scroll type air compressor with magnetic clutch and power connected diagram:

Among the figure: 1 scroll type air compressor, 2 motor, 3 gas holder, 4 pressure gauges, 5 safety valves, 6 pressure relayes, 7 suction ports, 8 outlet pipes, 9 draining valves, 10 oil pipes, 11 solenoid valves, 12 pressure regulator valves, 13 outlet valves, 14 big belt pulleys, 15 small belt pulleys, 16 elastic couplings, 17 belts, 18 magnetic clutchs, 19 magnetic clutch armature, 20 bearings, 21 axle journals

In Fig. 1: scroll type air compressor 1 links to each other with motor 2 by elastic coupling 16, and air enters scroll type air compressor 1 through suction port 7, compressedly enters the gas holder 3 from outlet pipe 8, and high-pressure air is discharged for use through outlet valve 13.Lubricant oil in the gas holder enters in air compressor and the gas tank through suction port 7 through solenoid valve 11 and pressure regulator valve 12 by oil pipe 10 through draining valve 9, in compressed process, plays the effect of lubricated, sealing and cooling compressor volution blade.The 4th, pressure gauge, the 5th, safety valve, the 6th, pressure relay, solenoid valve 11 are to be unlikely to the excessive compressor that enters in order to control compressor lubricant oil when shutting down, and pressure regulator valve 12 is that control lubricant oil enters compressor under certain pressure.

Fig. 2 is that scroll type air compressor 1 is used belt, the tectonic maps that the belt pulley of belt pulley and motor 2 links to each other.

Fig. 3 is equipped with bearing 20 on the casing of scroll type air compressor 1, and magnetic clutch 18 is contained on the bearing 20, and magnetic clutch armature 19 is housed on axle journal 21.When the pressure in the gas holder 3 reaches rating value, pressure relay 6 action outage, the electromagnetic coil that makes magnetic clutch 18 is because of the no magnetic force of outage, and breaks away from clutch armature 19, belt pulley idle running, scroll type air compressor 1 is not worked at this moment.When the pressure in the gas holder 3 drops to rating value, pressure relay 6 action energisings, the electromagnetic coil of magnetic clutch 18 holds clutch armature 19 because of energising produces magnetic force, drives scroll type air compressor 1 running air is compressed.The work that scroll type air compressor is gone round and begun again is to reach the purpose of saving power and improving 1 life-span of scroll type air compressor.

Claims

1, a kind of scroll type air compressor is equipped with lubricant oil in gas holder, it is characterized in that: the lubricant oil in the gas holder enters air compressor by draining valve 9, oil pipe 10, solenoid valve 11 and pressure regulator valve 12 through suction port 7.

2, according to claims 1 described scroll type air compressor, it is characterized in that: bearing 20 is housed on casing, magnetic clutch 18 is housed on it, magnetic clutch armature 19 is housed on axle journal.The electromagnetic coil of magnetic clutch 18 is in pressure relay 6 put in circuit.
