Description

A kind of gs-oil separator

Technical field

The utility model relates to a kind of gs-oil separators, and gas and oil are begun to rehearse out by centrifugal separation.

Background technique

Screw compressor is widely used in each production since it has many advantages, such as that energy-efficient, noise is lower, runs smoothly In industry.Screw compressor is mainly formed by the dynamic and static vortex of two digamma function equation scrollworks is mutually ratcheting.Screw compressor passes through Oil supply system carries out feed lubrication to each component in compressor.And the refrigerant gas of lubricating oil and high temperature and pressure in compressor It is mixed to form fuel-air mixture, is discharged outside compressor after the compression of whirlpool disk, so that the oil mass in compressor be caused to reduce.

To solve the above problems, gas and oil separating plant usually is set in the exhaust ports of screw compressor in the prior art, To which lubricating oil be separated from refrigerant gas.But in existing gas and oil separating plant, exhaust passage has multiple mutation circle Face, and channel is narrow, will cause pressure at expulsion loss, increases compressor power consumption.

Utility model content

Based on problem and deficiency described in background technique, the utility model is intended to provide a kind of oil of no pressure at expulsion loss Gas separating device can be applicable to the occasion of any gas-liquid separation, especially be useful in screw compressor and use.

In order to achieve the above objectives, the utility model uses following technical scheme:

A kind of gs-oil separator, including cylindrical shell, the housing cavity forms exhaust passage, shell be equipped with into Port, the air inlet inclination are provided with housing exterior walls.

Preferably, the air inlet is down-set along a tangential direction relative to the shell inner peripheral surface, air inlet central axis Line and casing center axis angle are less than 90 degree.

Preferably, the housing bottom offers outage.

Preferably, the gs-oil separator further includes having positioning pipe, and the positioning pipe is fixedly connected with the casing and is connected to and sets It sets.

Preferably, sealing ring is equipped at the positioning pipe and housing connection surface.

Preferably, exhaust pipe is inserted in the positioning pipe.

The beneficial effects of the utility model are: inclination offers air inlet on the oil separator case of the utility model, It is vented tangentially entering obliquely from oil cavity cross-section, approach axis is tangential, the tangential entrance of gas on circular arc interface So that close to the gas rotating of inner walls, and rotation is lost in gas so that gas is first rotated down at greater than 90 ° of angles downwards Oil is discharged by the central axial direction of shell again after rotatory force.Therefore housing cavity is directly as exhaust passage, structure letter It is single, avoid the loss of pressure at expulsion.

Specific embodiment

The utility model is further described below in conjunction with the drawings and specific embodiments, but present embodiment is simultaneously It is not limited to content below, arbitrarily can change and implement in the range of the purport of lossless the utility model.

As shown in figure 3, the gs-oil separator 8 of the utility model includes cylindrical shell 21 and positioning pipe 22, the shell Body 21 is bolted to connection with positioning pipe 22 and is connected to setting, is equipped with sealing ring at positioning pipe 22 and 21 joint face of shell 23, exhaust pipe 9 is inserted in positioning pipe 22.

As seen in figures 3-6, the shell 21 is equipped with an air inlet 24, and the inclination of air inlet 24 is provided with outside shell 21 Wall.Air inlet 24 is down-set along a tangential direction relative to 21 inner peripheral surface of shell, 24 central axis of air inlet and shell 21 Central axis angle is less than 90 degree.

As Figure 7-8, when being mixed with the refrigerant gas of lubricating oil and entering 21 inner cavity of shell from air inlet 24, gas Approach axis is downwardly into along 21 inner peripheral surface tangential direction of shell, so that gas is downward close to the inner wall rotation of shell 21 Movement, and downward angle is at greater than an angle of 90 degrees.After gas is rotated downwardly to bottom, gas loses the power of rotation, later It is discharged upwards by the central axial direction of shell 21 again.Therefore housing cavity will not be because of collision directly as exhaust passage, gas Abrupt interface and cause stress loss.

Effect of the gas through centrifugal force is attached to mist of oil on the inner wall of shell 21, and the bottom of shell 21 opens up an outage 25, lubricating oil converges into downwards 21 bottom of shell along 21 inner wall of shell by gravity, and is back to scroll compression by outage 25 In contracting machine.

The utility model gs-oil separator 8 can be applied to any required occasion for carrying out gas-liquid separation, be not limited solely to point From refrigerant gas and lubricating oil.Preferably, the utility model gs-oil separator 8 can be widely applied to the gas of screw compressor Liquid separation.Fig. 1-2 shows the scroll compressor structure schematic diagram using the utility model gs-oil separator 8, screw compressor Including shell 1, main shaft 2, end cap 3, fixed scroll 4, movable orbiting scroll 5, support frame 6, driving motor 7, gs-oil separator 8, cross slip-ring 14, the shell 1 is bolted connection with the end cap 3.Be equipped in shell 1 main shaft 2, driving motor 7, support frame 6, Cross slip-ring 14, fixed scroll 4 and movable orbiting scroll 5.

Support frame as described above 6 is fixed in shell 1, and one end of main shaft 2 is connected by bearing and the rotation of support frame as described above 6 It connects.The other end of the main shaft 2 is connect by bearing with 1 lower rotation of shell.The rotor of the driving motor is fixed at On main shaft 2, stator is fixed at 1 inner sidewall of shell.6 upper surface of support frame as described above is equipped with fixed scroll 4, in the fixed scroll 4 Equipped with movable orbiting scroll 5.

Integrally formed with crankpin 16,16 end sleeve of crankpin is equipped with axle sleeve 15, described dynamic for one end of the main shaft 2 Disk 5 bottom in whirlpool is rotatablely connected by bearing and the axle sleeve 15.The cross slip-ring 14 be set to support frame 6 and movable orbiting scroll 5 it Between.The fixed scroll 4, movable orbiting scroll 5 are set to 17 side of gasket, and support frame as described above 6 is set to 17 other side of gasket.

The side wall of the shell 1 offers inlet channel 10, and the side wall of the end cap 3 offers exhaust passage 11, described End cap 3 and the sealing of fixed scroll 4 form high pressure chest 13, and the shell 1 is enclosed low pressure chamber 12, exhaust passage 11 with support frame 6 Place is equipped with gs-oil separator 8.

As shown in Fig. 2, 4 surface of fixed scroll offers lubricant passage way 18, the oil inlet end of shown lubricant passage way 18 is equipped with Strainer 19.The mixed gas of system refrigerant and lubricating oil is sucked in screw compressor low pressure chamber 12 by inlet channel 10, through dynamic After whirlpool disk 5 and fixed scroll 4 are compressed, the gas of high temperature and pressure enters in high pressure chest 13, and the mist of oil in high pressure chest mixed gas is through oil The effect of gas separating device 8 becomes oil droplet and is back in high pressure chest, and flows into low pressure chamber 12 through lubricant passage way 18 in fixed scroll 4, To effectively reduce the loss of lubricating oil in screw compressor.
