Description

Oil blocking assembly for compressor

Technical Field

The utility model relates to a compressor technical field, concretely relates to oil blocking component that compressor was used.

Background

The bottom of the compressor is generally provided with refrigerant oil for lubricating the kinematic pairs and reducing the temperature of the pump body. Specifically, the refrigeration oil can enter from the tail of the crankshaft along with the rotation of the crankshaft and reach the top of the crankshaft along a spiral oil groove on the crankshaft, and due to the fact that the crankshaft and the main end have certain offset, the refrigeration oil can be thrown out when the crankshaft rotates, part of the thrown-out refrigeration oil can be sucked into a pump body from a muffler air suction port in a compressor and then is compressed by a piston together with sucked gas and is discharged into a refrigeration system, the stability of the refrigeration system is reduced, and the reduction of cooling and lubricating effects can be caused due to the reduction of the refrigeration oil.

Therefore, an oil baffle sheet is generally sleeved on an exhaust pipe in the compressor and used for preventing the frozen oil from dropping or sputtering to a silencer air suction port positioned below the side of the exhaust pipe, but because the oil baffle sheet is only of a sheet structure, the frozen oil drops on the oil baffle sheet and then converges together, part of the frozen oil overflows to one side close to the silencer air suction port, and part of the frozen oil which is difficult to avoid in the overflowing process splashes to the silencer air suction port; in addition, once a large amount of the refrigeration oil drops on the oil baffle sheet in a short time, the oil baffle sheet cannot temporarily store a large amount of the refrigeration oil, and the oil baffle effect of the oil baffle sheet is extremely limited.

In view of the above problems, it is desirable to design an oil baffle assembly for a compressor.

SUMMERY OF THE UTILITY MODEL

In order to prevent effectively that the refrigeration oil from spilling over and sputtering, the utility model provides an oil blocking component that compressor was used can let the realization that the refrigeration oil can be better keep in and the water conservancy diversion to avoid the refrigeration oil to get into muffler suction opening department.

In order to solve the technical problem, the utility model discloses specifically adopt following technical scheme:

the utility model provides a fender oil subassembly that compressor was used, includes base and oil scraper ring, the one end of oil scraper ring with the top fixed connection of base, the other end of oil scraper ring deviates from the base upwards extends, the hole of stepping down has been seted up to the centre of base for the blast pipe in the compressor is established to the cover, square oil drain hole has still been seted up at the top of base, just square oil drain hole is located the inboard of oil scraper ring.

Compared with the prior art, the utility model discloses following beneficial effect has:

the base is sleeved on the exhaust pipe of the compressor, a basic structure similar to an oil baffle sheet is constructed, the base is provided with the square oil discharge hole, so that the refrigerant oil can conveniently drip to the bottom in the compressor through the square oil discharge hole, and the refrigerant oil is effectively prevented from flowing to one side of the air suction port of the silencer after being gathered; in addition, set up the oil scraper ring on the base, further prevented overflowing and sputtering of refrigeration oil, promoted the oil blocking ability of oil blocking subassembly by a wide margin, let the refrigeration oil can be better realize keeping in and the water conservancy diversion on oil blocking subassembly.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1-2, the utility model provides a technical solution: the utility model provides a fender oil assembly that compressor was used, includes base 10 and oil slinger 13, oil slinger 13 one end with base 10's top fixed connection, oil slinger 13's the other end deviates from base 10 upwards extends, the hole 14 of stepping down has been seted up to the centre of base 10 for the blast pipe 19 in the compressor is established to the cover, square oil drain hole 11 has still been seted up at base 10's top, just square oil drain hole 11 is located oil slinger 13's inboard.

In the preferred embodiment of the present invention, as shown in fig. 2, the square oil drainage hole 11 is distributed around the circumference of the abdicating hole 14, so that the outflow rate of the refrigerant oil can be increased in unit time, and the excessive convergence of the refrigerant oil on the oil blocking assembly can be avoided.

In the preferred embodiment of the present invention, as shown in fig. 1, the inner wall of the oil deflector ring 13 is provided with an oil absorption layer 15 in a surrounding manner, and the oil absorption layer 15 is preferably made of polyethylene oil absorption fiber, so that the oil absorption speed and the oil absorption rate of the oil absorption layer 15 can be effectively increased, and the oil deflector ring is also convenient to use and recover.

In the preferred embodiment of the present invention, as shown in fig. 1 and fig. 3, one side of the oil retainer 13 is provided with a side door 17 which can be opened and closed, and the side door 17 is provided with a handle 18, so that the side door 17 can be opened conveniently to discharge the frozen oil from the side door 17, thereby providing more channels for the discharge of the frozen oil; during the specific use, the sealing washer should be preferred all around of side door 17, promotes its sealed effect, and one side of side door 17 must deviate from muffler induction port 20 department, prevents that the freezing oil from dripping to muffler induction port 20 department.

In the preferred embodiment of the present invention, as shown in fig. 1, fig. 2 and fig. 3, the sleeve 12 is disposed in the center of the top of the base 10, and the inner diameter of the sleeve 12 is smaller than the inner diameter of the yielding hole 14, so that the exhaust pipe of the compressor can be conveniently in interference fit, and the oil blocking component can be more firmly disposed on the exhaust pipe 19 of the compressor.

In the preferred embodiment of the present invention, as shown in fig. 1, the four corners of the base 10 are provided with rounded corners 16, so as to avoid other parts and pipelines in the base 10 cost-effective compressor.

The utility model discloses a preferred embodiment, as shown in fig. 1, fig. 2, fig. 3, square oil drain hole 11 is when concrete design, and the preferred hole 14 of stepping down that is close to avoids the refrigeration oil to be close to muffler induction port 20 when flowing out via the hole 14 of stepping down, and the overall dimension of base 10 should be as far as more of design under the prerequisite of not interfering to the inside formation of compressor to this forms better guard space to muffler induction port 20

The working principle is as follows: establish in the blast pipe 19 of compressor through keeping off oily subassembly cover for the refrigeration oil that is located fender oily subassembly top can only at first drip at the top of base 10, and discharge via square oil drain hole 11, because the combined design of oil slinger 13 and oil absorption layer 15, make the refrigeration oil can not sputter away, and can a large amount of keep in fender oily subassembly, then discharge via square oil drain hole 11 or side door 17, the oil effect of keeping off has been promoted by a wide margin, refrigeration oil has been avoided getting into muffler suction inlet department.
