Description
Technical Field
The utility model belongs to the technical field of vehicle air conditioner compressor, a vehicle air conditioner compressor casing oil baffle structure is related to.
Background
The rotary vane compressor shell has the following functions:
1. the compressor shell is matched with the compressor head cover to form a closed body, the internal rotating part is sealed, and a main structure of the compressor is formed and connected with the whole vehicle; (ii) a
2. The compressor shell is provided with an exhaust port, the bottom of the shell is smooth, and the bottom of the compressor shell has an oil storage function.
The problem that smooth design in current compressor housing bottom exists is: when the compressor works, the rear part of the shell is a high-pressure cavity of the compressor, high-temperature and high-pressure refrigerant gas separates lubricating oil from the refrigerant through an oil separator structure at the rear part of a revolving body of the compressor, the refrigerant enters an air conditioning system pipeline through an exhaust port in the shell, and the lubricating oil is dripped into the bottom of the shell of the compressor under the action of gravity and lubricates internal parts of the compressor through oil circuit circulation. However, the smooth design of the bottom of the existing compressor shell can cause that a large amount of lubricating oil enters a pipeline along with a refrigerant when the refrigerant is discharged, so that the lubricating oil in the compressor is reduced, and in severe cases, the inside of the compressor is blocked due to insufficient lubrication, and finally the compressor fails, so that the use of customers is affected.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's is not enough, provides a vehicle air conditioner compressor casing oil baffle structure, and this structure makes the compressor in the high temperature high-pressure gas working process of discharging, and a large amount of lubricating oil are blocked by the oil baffle, and only few lubricating oil can be along with the refrigerant entering system pipeline to guarantee the lubrication of the inside spare part of compressor.
The purpose of the utility model is realized like this: the utility model provides a vehicle air condition compressor casing oil baffle structure, the blind end upper portion of casing is equipped with the gas vent, is close to closed end department and is equipped with oil separator, oil separator installs on compressor solid of revolution rear end plate, the inner wall of casing is equipped with the oil baffle towards the extension of casing center department, the oil baffle is located the oil separator below, and is higher than the oil storage face of casing bottom, makes the compressor when discharge high temperature high-pressure gas, and a large amount of lubricating oil of casing bottom is blocked by the oil baffle, reduces lubricating oil and runs off, the horizontal section face thickness of oil baffle is reduced towards casing center department by the inner wall of casing gradually.
Furthermore, the oil baffle plates are arranged in two numbers, are respectively arranged at the lower part in the compressor shell and at the part which does not interfere with the oil separator, and one of the oil baffle plates is positioned in the horizontal direction.
Since the technical scheme is used, the utility model discloses following beneficial effect has:
1. the utility model discloses oil baffle structure has been designed on the compressor housing to set up oil baffle below the compressor oil separator, make the compressor discharge high temperature high pressure gas working process, a large amount of lubricating oil of compressor housing bottom is blocked by oil baffle, only few lubricating oil can get into the system pipeline through the gas vent on compressor housing upper portion along with refrigerant gas, avoided lubricating oil to get into the system pipeline along with refrigerant gas a large amount, influence the lubricated problem of gyration spare part in the casing, thereby guarantee the normal operation of compressor inside spare part;
2. the height of the oil baffle is determined according to the length of a rotary body in the compressor and the structure of surrounding parts; the oil baffle plate is designed into a structure that the thickness of a transverse section plane is gradually reduced from the inner wall surface of the shell to the center of the shell on the premise of not interfering with the revolving body, the strength of the oil baffle plate can be enhanced while oil is blocked, and the oil baffle plate is designed below the oil separator of the compressor and can play roles in positioning and preventing mistakes in mounting the revolving body.

Detailed Description
The embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1-2, in order to avoid the situation that lubricating oil enters a system pipeline along with refrigerant gas and affects the lubrication of rotating parts, an oil baffle 4 is extended from the inner wall of the shell 1 to the center of the shell, the oil baffle 4 is located below the oil separator 3 and is higher than the oil storage surface at the bottom of the shell 1, the height of the oil baffle is determined according to the length of the rotating body, the height of the oil baffle 4 in the embodiment is smaller than the dimension from the outer peripheral surface of the oil separator 3 to the inner wall surface of the shell 1, so that when the compressor discharges high-temperature high-pressure gas, a large amount of refrigerant at the bottom of the shell 1 is blocked by the oil baffle 4, and only a small amount of lubricating oil enters the system pipeline along with the refrigerant gas, the lubricating oil loss is reduced, and the lubrication of the internal parts of the compressor is ensured.
As shown in fig. 3, in this embodiment, the thickness of the transverse section of the oil baffle 4 gradually decreases from the inner wall of the casing to the center of the casing, and the adoption of this structure enhances the strength of the oil baffle and facilitates the process drawing.
As shown in fig. 2, two oil baffle plates 4 are provided in the present embodiment, and the two oil baffle plates are respectively provided at the lower part in the compressor housing and at the position not interfering with the oil separator to form a barrier to the lubricating oil at the bottom of the housing, wherein one oil baffle plate is located in the horizontal direction, and the angle between the other oil baffle plate and the horizontal direction depends on the structure of the components.
The design of the position of the oil baffle plate 4 is generally designed under the compressor oil separator on the premise of not interfering with the revolving body in the shell, and can play the roles of positioning and mistake proofing for the installation of the revolving body.
The utility model discloses set up the fender oil plate structure and can reduce the compressor in lubricating oil run off the not enough dead trouble of card when inside spare part operation that leads to of lubricating oil, reduce after-sales maintenance cost.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
