Description
Technical field
The present invention relates to a kind of oil level control device of Semi-closed piston compressor.
Background technology
At present, it is by shell casting using motor cavity and the shoe cream room of the Semi-closed piston compressor of splash lubrication
What opening directly communicated.Such structure Shortcomings, casting opening is bigger, the level height phase of shoe cream room and motor cavity
Deng, in compressor operating, in motor cavity substantial amounts of lubricating oil can follow refrigerant enter refrigeration pipe in, the refrigerant of circulation
Band oil mass is too high, and this will influence the performance of refrigeration system.
The content of the invention
In order to solve problems of the prior art, the present invention provides a kind of oil level control of Semi-closed piston compressor
Device, it can solve the problem that the problem of existing refrigerant band oil mass is big during compressor operating.
Technical scheme is as follows：
A kind of oil level control device of Semi-closed piston compressor, including case partition, valve body and activity template, the motor of compressor
Chamber and shoe cream room are located at case partition both sides, and the through hole of a connection motor cavity and shoe cream room, valve body installation oil storage are set on dividing plate
The through hole of chamber side, through hole set an activity template close to shoe cream room side, and support plays position-limiting action to activity template, works as shoe cream room
Oil level when being higher than motor cavity, activity template is located at valve body lowermost end, and now activity template is by the passage between motor cavity and shoe cream room
Shut, lubricating oil will not flow into motor cavity from shoe cream room；When the oil level in motor cavity is higher than shoe cream room, the lubrication in motor cavity
Oil flows into shoe cream room after activity template is pushed away into valve body bottom, and the one-way flow of lubricating oil is realized by activity template, shoe cream room
Lubricating oil will not flow direction motor chamber, the refrigeration oil of motor cavity can flow to shoe cream room, a small amount of profit is only had in such motor cavity
Lubricating oil, refrigerant band oil mass is very low during compressor operating.
Wherein, the support that position-limiting action is played to activity template is provided with the valve body.
Wherein, the support both sides are provided with sealing ring, prevent the oil stream in shoe cream room from entering motor cavity.
Wherein, the top that the valve body is located in shoe cream room is provided with back-up ring, and a number of perforate is provided with back-up ring.
Wherein, the valve body is disposed in proximity to the position of shoe cream room bottom, and small more than zero degree with the formation of shoe cream room base
The angle of Yu Jiushi degree.
The present invention has the advantages that：
1st, the present invention can solve the problem that the problem of existing refrigerant band oil mass is big during compressor operating.
2nd, the present invention is simple in construction, is easy to dismount.
Brief description of the drawings
Fig. 1 is the sectional structural map of the oil level control device of Semi-closed piston compressor of the present invention.
Reference is expressed as in figure：
1- valve bodies, 2- supports, 3- back-up rings, 4- activity templates, 5- sealing rings, 6- shoe cream rooms, 7- motor cavities, 8- case partitions.
Embodiment
The present invention will be described in detail with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of oil level control device of Semi-closed piston compressor, including case partition 8, valve body 1 and activity
Piece 4, the motor cavity 7 and shoe cream room 6 of compressor are located at the both sides of case partition 8, a connection motor cavity 7 and oil storage are set on dividing plate 8
The through hole of chamber 6, valve body 1 install the through hole of the side of shoe cream room 6, and through hole sets an activity template 4 close to the side of shoe cream room 6, works as storage
When the oil level of oil pocket 6 is higher than motor cavity 7, activity template 4 is located at the lowermost end of valve body 1, and now activity template 4 is by motor cavity 7 and shoe cream room 6
Between passage shut, lubricating oil will not from shoe cream room 6 flow into motor cavity 7；When the oil level in motor cavity 7 is higher than shoe cream room 6,
Lubricating oil in motor cavity 7 flows into shoe cream room 6 after activity template 4 is pushed away into the bottom of valve body 1.
Preferably, the support 2 that position-limiting action is played to activity template 4 is provided with the valve body 1.
Preferably, the both sides of support 2 are provided with sealing ring 5, prevent the oil stream in shoe cream room 6 from entering motor cavity 7.
Preferably, the top that the valve body 1 is located in shoe cream room 6 is provided with back-up ring 3, and certain amount is provided with back-up ring 3
Perforate.
Preferably, the valve body 1 is disposed in proximity to the position of the bottom of shoe cream room 6, and is formed with the base of shoe cream room 6 and be more than zero
Angle of the degree less than 90 degree.
The use process of the present invention：
Referring to Fig. 1, case partition 8, the shoe cream room of case partition 8 are provided with the motor cavity 7 and shoe cream room 6 of compressor housing
6 sides are provided with valve body 1, and valve body 1 plays position-limiting action built with activity template 4, support 2 to activity template 4, when the oil level of shoe cream room 6 is high
When motor cavity 7, activity template 4 is located at the lowermost end of valve body 1, and now activity template 4 seals the passage between motor cavity 7 and shoe cream room 6
Extremely, lubricating oil will not flow into motor cavity 7 from shoe cream room 6；When the oil level in motor cavity 7 is higher than shoe cream room 6, in motor cavity 7
Lubricating oil flows into shoe cream room 6 after activity template 4 is pushed away into the bottom of valve body 1, so ensures that the freezing oil level in motor cavity 7 begins
Shoe cream room 6 is not higher than eventually, refrigerant band oil mass when reducing compressor operating.
