Abstract
The utility model provides a compressor upper cover with oil strain function, belongs to compressor technical field, and it is complicated to have solved present compressor upper cover oil filter device structure, and manufacturing cost is high, and is not quick detachable, and the blast pipe including the lid, is not installed to convenient to use's problem on the lid, the blast pipe bottom is provided with internal thread, the threaded pipe of the last threaded connection of internal thread, and screwed pipe bottom and hollow cylindric base intercommunication, the diameter of base is greater than the diameter of blast pipe, is provided with a plurality of inlet port on the base lateral wall. The utility model discloses compressor upper cover oil filter device simple structure, low in manufacturing cost easily dismantles convenient to use.
Description
Technical field
The utility model belongs to Compressor Technology field, particularly a kind of compressor accessory.
Background technique
In the compressor of prior art, outlet pipe is directly inserted into the inside of housing by upper cover, when compressor carries out work, in oilhole in crankshaft rotating band dynamic crankshaft, the screw of bottom rotates together, screw is transported to lubricant oil the lubrication of top for top moving element of compressor from the oil groove bottom compressor, to reduce friction.But because outlet pipe is just to bent axle oil outlet, and outlet pipe is smooth cylinder, do not stop, therefore high pressure refrigerant gas is easy to parts of lubricating oil to take away, and is discharged, cause loss of lubrication by outlet pipe; Meanwhile, with lubricant oil in cold media air, be also unfavorable for the operation of compressor, reduce the refrigerating capacity of compressor.
Application number be 200410072367 Chinese invention disclose a kind of compressor top cover with filter screen, cover on the compressor and include, be embedded in the tenminal block that covers and be embedded in the refrigerant discharge tube covered, wherein the suction port of refrigerant discharge tube is positioned at the inner side of upper cover, the exhaust port of refrigerant discharge tube is positioned at the outside of upper cover, be positioned at the suction port place of refrigerant discharge tube in the inner side of upper cover, be provided with oil resistance device.Oil resistance device includes: the filter screen stand of filter screen and support filter screen, filter screen is fixedly embedded on filter screen stand, and filter screen stand is fixed on the inner side of upper cover.This invention is provided with oil resistance device at the upper cover of compressor, compressor cold oil can not be directly injected in the circulatory system of air-conditioning, greatly improve the efficiency of air conditioner; Meanwhile, install filter screen additional, the impurity that the wearing and tearing of compressor internal cause are produced can not enter the circulatory system, but is deposited in bottom compressor, thus improves the cycle efficiency of air conditioner, extends the working life of compressor.
Application number be 201010300971 Chinese model utility disclose a kind of superstructure of compressor, described compressor comprises housing, housing is by cylindrical shell, the composition such as upper cover and lower cover, motor and compressor assembly are installed in housing, motor is by stator, the composition such as rotor and bent axle, compressor assembly is by cylinder, the composition such as upper bearing and lower bearing, upper covering is provided with outlet pipe, outlet pipe is directly inserted into the inside of housing by upper cover, the lower end of described upper cover is provided with top bearing, the central authorities of top bearing are provided with the fixing part for stable bent axle to lower process, top bearing is provided with multiple uniform relief opening, fixing part is formed with multiple uniform oil outlet.The structure barrier of this invention lubricant oil is taken away by high pressure refrigerant gas, decreases the loss of lubricant oil, improves the refrigerating capacity of compressor; Meanwhile, bent axle upper end is stretched in fixing part, reduces the vibration of compressor, improves the reliability of compressor.
Above-mentioned compressor upper cover oil filter complex structure, manufacture cost is high, not quick detachable, is not easy to use.
Model utility content
For solving existing compressor top cover oil filter complex structure, manufacture cost is high, not quick detachable, and be not easy to the problem used, the utility model provides a kind of compressor top cover with oil filtering function, and its technological scheme is as follows:
There is a compressor top cover for oil filtering function, comprise lid, lid is provided with outlet pipe;
Be provided with internal thread segment bottom outlet pipe, internal thread segment has been threaded threaded pipe, is communicated with bottom threaded pipe with the base of the cylindrical shape of hollow, and the diameter of base is greater than the diameter of outlet pipe, base side wall is provided with several inlet holes.
Preferably, the madial wall of described base is provided with filter screen.
Preferably, the internal diameter of described threaded pipe is 3.2 centimetres.
Preferably, described base side wall is circumferentially evenly equipped with four inlet holes, the diameter of inlet hole is 1.8 centimetres.
Preferably, the mesh diameter of the filter screen on described base is 1.6 millimeters.
During use, oil filter can be screwed in the internal thread segment bottom outlet pipe by threaded pipe, lubricant oil is stopped by base, avoids and is taken away by high pressure refrigerant gas, decreases the loss of lubricant oil, improves the refrigerating capacity of compressor.Base in the utility model and threaded pipe form oil filter.
The utility model has following beneficial effect: the utility model compressor top cover oil filter structure is simple, low cost of manufacture, is easy to dismounting, easy to use.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
