Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of air compressor, particularly a kind of oil free screw formula air compressor.
Background technique
In industrial production, air compressor (claiming air compressor again) is a kind of widely used equipment, and it is that atmosphere is added a kind of engineering equipment that presses to pressurized gas.
For example, " single-screw air compressor " that Chinese patent CN2589694Y provides, it is that the shell etc. of cavity is formed by screw rod and inside, and the quantity of screw rod is one.Be provided with a pair of star-wheel that is meshed with screw rod at screw rod monosymmetric, formed two complete axisymmetric closed compression chambeies like this, be in the air pressurized in above-mentioned two closed compression chambeies, thereby discharge pressurized gas.
But above-mentioned single-screw air compressor and most existing air compressor all adopt fluid to realize cooling, lubricated and sealing.For industry requirement pressurized air such as picture medicine, food, electronics, senior spraying, sophisticated technology fields, the absolute occasion of not having oil, the exhaust end base of oil injection threaded bolt machine does not just meet usage requirement, and existing dry type does not have oily machine, no matter be piston type or screw type, owing to be dry friction, gear efficiency is very low, working life is very short, and operation, maintenance cost is very high.
Summary of the invention
The purpose of this utility model is at the air-polluting problem of existing in prior technology compressor oil, and the water lubrication oil free type that a kind of operating cost is low, stability in use is high air compressor is provided.
The purpose of this utility model can realize by following technical proposal: a kind of water lubrication screw air compressor, comprise that an inside is the housing of cavity, axial restraint has screw rod and be provided with bearing between screw rod and housing in housing, also be connected with two spider pieces in the described housing with some teeth, the axis of two spider pieces and screw axis are perpendicular and spider piece is symmetrical is positioned at the screw rod both sides, the teeth of spider piece are meshed with the teeth of above-mentioned screw rod, have the import and the outlet that communicate with cavity on the described housing, it is characterized in that, be provided with the sealing mechanism that the flowing medium that can stop in the housing cavity enters the bearing place between described bearing and the screw rod.
In this water lubrication screw air compressor, screw rod drives its rotation by power mechanism (as: motor).In the cavity of housing, have water, in the screw rod rotation process two spider pieces little by little with screw engages, make under the lubricated and seal action of water that atmosphere is unidirectional all the time to discharge by outlet, make that what discharged by the outlet port is pressurized gas.
Meanwhile, under the effect of sealing mechanism, make water can not enter the bearing place all the time, thereby improved the working life of bearing.
In above-mentioned water lubrication screw air compressor, the quantity of described bearing is two, and these two bearings are enclosed within the two ends of screw rod respectively.Make screw rod in housing, to rotate smoothly by these two bearings.
In above-mentioned water lubrication screw air compressor, described sealing mechanism is mechanical seal, and mechanical seal comprises inner seal ring and exterior seal ring.
By the sealing between inner seal ring realization Sealing and the screw rod end, by the sealing between exterior seal ring realization Sealing and the housing.
In above-mentioned water lubrication screw air compressor, described bearing is made by graphite material.Adopt this material to make not only waterproof of bearing, and scratch-resistant performance is good.
As another scheme, in above-mentioned water lubrication screw air compressor, described bearing is made by carbofrax material.Adopt this material to make not only waterproof of bearing equally, and scratch-resistant performance is good.
Compared with prior art, this water lubrication screw air compressor is because bearing adopts nonmetallic material, and employing water is medium in the housing, has so not only reduced the operating cost of air compressor, and the stability in use of air compressor also obtains improving.
Simultaneously, sealing mechanism makes water can't enter the bearing place, the further like this stability in use that improves air compressor
Description of drawings
Fig. 1 is the sectional structure schematic representation of this water lubrication screw air compressor.
Fig. 2 is along the A-A sectional structure schematic representation among Fig. 1.
Among the figure, 1, housing; 1a, import; 1b, outlet; 2, screw rod; 3, spider piece; 31, coupling shaft; 4, bearing; 5, mechanical seal; 6, sliding bearing.
Embodiment
As depicted in figs. 1 and 2, this water lubrication screw air compressor is used for compressed atmosphere, thus the output pressurized gas.It is made up of housing 1, screw rod 2, spider piece 3 etc.
Also be provided with two spider pieces 3 in housing 1, the axis of these two spider pieces 3 is all perpendicular with the axis of screw rod 2, and two spider pieces 3 are positioned at the both sides of screw rod 2, has some teeth on the spider piece 3, and two spider pieces 3 all are meshed with screw rod.In the present embodiment, the two ends of spider piece 3 have coupling shaft 31, are provided with sliding bearing 6 between coupling shaft 31 and the housing 1.
Between bearing 4 and screw rod 2, be provided with the mechanical seal 5 that the flowing medium that can stop in housing 1 cavity enters bearing 4 places.
During the work of this water lubrication screw air compressor, driven by motor screw rod 2 rotates, because two spider pieces 3 mesh with screw rod 2 all the time.In the gap of having eliminated under the effect of water between spider piece 3 and the screw rod 2, formed a plurality of closed compression chamber in screw rod 2 rotation processes, in the screw rod 2 continuous rotation processes just by the outlet 1b place of housing 1 output pressurized gas.
Simultaneously, under the effect of sealing mechanism, make water can not enter bearing 4 places.And bearing 4 employing nonmetallic material are made the energy waterproof.
