Abstract
A kind of single screw compressor casing improving water spray mouth structure, corresponding to the setting of pitch tooth socket bosom in the inner wall of casing, there are two hole for water sprayings one, it is characterized in that, hole for water spraying two there are two being added in the corresponding position close to exhaust end of inner wall of casing, Packed annular chamber is set between the casing and discharge end bearings seat, water pump outside annular chamber connection, the hole for water spraying one and hole for water spraying two are connected to by axial passage with annular chamber, are supplied water by annular chamber.The utility model can reduce temperature rise and lubrication, improve efficiency, improve its reliability and stability, service life greatly prolongs by adding water jet in rational position.
Description
Technical field
The utility model belongs to oil-free water-lubricating single screw compressor technical field, in particular to a kind of improvement water jet knot
The single screw compressor casing of structure.
Background technique
When oil-free water-lubricating single screw compressor works, as screw rod continues to rotate, gas is turned by star-wheel in screw rod tooth socket
Dynamic to squeeze, pressure rises greatly, and temperature continues to increase therewith.Excessively high temperature is easy to make screw rod and casing expanded by heating or locking, or
Components are damaged, and rely on increase fit clearance that locking is avoided to will increase tolerance loss, reduce efficiency.
To solve this problem, two water jets, spray are provided on oil-free water-lubricating single screw compressor casing inner wall
Mouth positional symmetry is arranged in the middle part of screw rod, temperature rise can be reduced to a certain extent, however as what is required compressor operating
It improves, in the case where long-play, this kind of structure can not uniformly reduce running extruder temperature, and lubricant effect
It not can guarantee, cause to generate screw rod locking phenomenon.
Summary of the invention
In order to overcome the disadvantages of the above prior art, the purpose of this utility model is to provide a kind of improvement water spray mouth structures
Single screw compressor casing can reduce temperature rise and lubrication, improve energy by adding water jet in rational position
Effect, improves its reliability and stability, service life greatly prolongs.
To achieve the goals above, the technical solution adopted in the utility model is:
A kind of single screw compressor casing improving water spray mouth structure, corresponds to pitch tooth socket most in the inner wall of casing 4
There are two hole for water sprayings 1 for depths setting, which is characterized in that has additional two in the corresponding position close to exhaust end of the inner wall of casing 4
A hole for water spraying 22, is arranged Packed annular chamber 3 between the casing 4 and discharge end bearings seat 5, and annular chamber 3 connects outside
Water pump, the hole for water spraying 1 and hole for water spraying 22 are connected to annular chamber 3 by axial passage 8, are supplied water by annular chamber 3.
The water spraying direction of the hole for water spraying 1 is that the screw channel of screw rotor 7 is tangential.
The water spraying direction of the hole for water spraying 22 is vertical with screw shaft 6.
4 axial channels 8 are provided in the casing 4, each hole for water spraying 1 and each hole for water spraying 22 are distinguished
It is connected to by 1 channel 8 with annular chamber 3.
Compared with prior art, the utility model has the beneficial effects that
1, only in screw rod tooth socket bosom, there are two cooling and lubricating hole for water sprayings for original single screw compressor, but in compression process
Suction end has just started that compression pressure is low, and temperature is low, and exhaust end pressure is high, and temperature height does not have cooling and lubricating hole for water spraying instead.Pass through
Increase by 2 cooling and lubricating hole for water sprayings, not only changed lubrication state, but also the liquid film for declining exhaust end temperature, and generating
Leakproofness is improved, efficiency is improved, lower power consumption.
2, the utility model hole for water spraying arrangement form and axial water spray position are to guarantee that lubrication can obtain maximum energy
Imitate the key of ratio.
Detailed description of the invention
Fig. 1 is hole for water spraying in casing circumferentially arrangement schematic diagram.
Fig. 2 is that hole for water spraying arrow along chassis axial arrangement schematic diagram, figure is water (flow) direction.
Specific embodiment
The embodiments of the present invention is described in detail with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of single screw compressor casing improving water spray mouth structure, the screw rod with screw rotor 7
Axis 6 is mounted in casing 4 by air-breathing end bearing block 9 and discharge end bearings seat 5, and the inner wall of casing 4 corresponds to pitch tooth socket
There are two positioned at same circumference and about centrosymmetric hole for water spraying 1, the water spraying direction of hole for water spraying 1 is spiral shell for bosom setting
The screw channel of bar rotor 7 is tangential.
In order to overcome the low screw rod temperature distortion of water spray lubrication efficiency in traditional structure uneven, or there is screw rod and casing
Locking phenomenon corresponds to screw rod in the inner wall of casing 4 and adds close to the position (when pressure is close maximum in screw slot) of exhaust end
There are two positioned at same circumference and about centrosymmetric hole for water spraying 22, the water spraying direction of hole for water spraying 22 is vertical with screw rod.
Packed annular chamber 3 is set between casing 4 and discharge end bearings seat 5, annular chamber 3 connects external water pump,
4 axial channels 8 are provided in casing 4, each hole for water spraying 1 and each hole for water spraying 22 pass through 1 channel 8 and ring respectively
Shape chamber 3 is connected to, and is supplied water by annular chamber 3.
Lubrication is abundant when the position of two hole for water sprayings 1 and two hole for water sprayings 22 makes compressor operation, and screw rod is heated
Deformation uniformly, guarantees that back lash is accurate, stablizes, improves efficiency.
When work, under motor effect, screw shaft 6 is rotated, and compressor inlet end and exhaust end can then generate pressure difference, is moistened
Sliding cooling water enters the ring between casing 4 and discharge end bearings seat 5 via system pipeline, water inlet under the action of pressure difference
In shape seal chamber 3, and by the 4 month ages of a draught animal in the same plane with annular chamber 3, respectively into the axis on 4 barrel of casing
To channel 8 be ejected into the screw channel of rotation, make then by the hole for water spraying 1 and hole for water spraying 22 that are communicated with inner wall
Cooling and lubricating water energy is equably sprayed at screw rod from the closed different working face of star-wheel, screw rod and casing, reaches cooling profit
Sliding purpose.The structure type is simple, practical, reliably.
