Background technique
Semi-closed compressor is widely used in the various industrial departments such as refrigeration, power, chemical industry, machinery, due to semiclosed pressure
Contracting machine has many advantages, such as that noise is small, light-weight, small in size, reliable operation, and occupation rate in the market is very high.Semi-closed compressor
Motor usually is cooled down using the low-pressure low-temperature gas come out from evaporator, to reduce the operating temperature of motor, avoids motor
It is burnt since temperature is excessively high.
But since the relative mechanical movement between each components of semi-closed compressor generates friction, thus can be in unit
Portion, which generates some impurity and iron filings, these impurity and iron filings, to be flowed with refrigerant, finally enter gas via evaporator
Gas-liquid separation is carried out in liquid/gas separator, subsequently into compression and cooling motor is carried out in semi-closed compressor, so as to cause iron filings
It can be adsorbed onto the rotor surface of motor, be difficult to clean up, and since the gap between the stator and rotor of motor is very narrow, blocked up
It will affect the normal work of motor after plug, it is necessary to be removed before iron filings enter semi-closed compressor.Therefore, ability is needed
Field technique personnel develop a kind of semi-closed compressor group novel gas-liquid separator.
Utility model content
In order to solve the problems, such as how by iron filings enter semi-closed compressor before be removed, the utility model provides
A kind of semi-closed compressor group novel gas-liquid separator.
In order to achieve the above objectives, the utility model uses following technical scheme: a kind of semi-closed compressor group is with novel
Gas-liquid separator, the gas-liquid separator include gas-liquid separator shell, inlet pipe, outlet pipe, U-tube and for adsorbing the permanent of iron filings
Magnet, the inlet pipe, outlet pipe be set to gas-liquid separator shell on, the inlet pipe, outlet pipe with gas-liquid separator enclosure interior cavity
It connects, the U-tube is set in gas-liquid separator enclosure interior cavity, and the outlet pipe is in gas-liquid separator enclosure interior chamber
Intracorporal one end is connected with U-tube one end, and the U-tube other end is set as gas vent, and the inlet pipe is in gas-liquid separator
The intracorporal one end of enclosure interior chamber is set as inner port, and the position of the inner port is lower than the gas vent of U-tube, the gas-liquid
The bottom and two sidewalls of shell separator inner cavity are respectively equipped with a permanent magnet.
Preferably, the U-tube bottom is provided with an oilhole, and the oilhole is equipped with one layer of filter screen.
Based on the above-mentioned technical proposal, the utility model has following technological merit compared with prior art:
The utility model uses semi-closed compressor group novel gas-liquid separator, at the bottom of gas-liquid separator housing cavity
Portion and two sidewalls are respectively equipped with a permanent magnet, enter the iron filings in gas-liquid separator to magnetic absorption, with traditional technology phase
Than that can enter in semi-closed compressor with gas from the outlet pipe of gas-liquid separator to avoid iron filings, iron filings is avoided to be attracted to half
The rotor surface of hermetic compressor and the case where cause motor can not work normally.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model gas-liquid separator.
Fig. 2 is in specific embodiment of the present invention using the partial cutaway of the semi-closed compressor group of permanent magnet frequency conversion motor
View.
In figure: 1. gas-liquid separator shells, 2. inlet pipes, 2-1. inner port, 3. outlet pipes, 4.U shape pipe, 4-1. gas go out
Mouthful, 4-2. oilhole, 4-3. filter screen, 5. permanent magnets, 6. permanent magnet frequency conversion motor stators, 7. permanent magnet frequency conversion motor rotors.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.Following embodiment is only used for practical to this
It is novel to be explained, rather than the restriction to utility model.
Referring to Fig. 1, a kind of semi-closed compressor group novel gas-liquid separator, which includes gas-liquid separator
Shell 1, inlet pipe 2, outlet pipe 3, U-tube 4 and the permanent magnet 5 for adsorbing iron filings, the inlet pipe 2, outlet pipe 3 are set to gas-liquid separation
On device shell 1, the inlet pipe 2, outlet pipe 3 connect with 1 internal cavity of gas-liquid separator shell, and the U-tube 4 is set to gas-liquid
In 1 internal cavity of shell separator, the outlet pipe 3 is in the intracorporal one end of 1 inner chamber of gas-liquid separator shell and 4 one end of U-tube
It is connected, 4 other end of U-tube is set as gas vent 4-1, and the inlet pipe 2 is intracorporal in 1 inner chamber of gas-liquid separator shell
One end is set as inner port 2-1, and the position of inner port 2-1 is lower than the gas vent 4-1 of U-tube 4, the gas-liquid separator
The bottom and two sidewalls of 1 inner cavity of shell are respectively equipped with a permanent magnet 5.
4 bottom of U-tube is provided with oilhole a 4-2, the oilhole 4-2 and is equipped with one layer of filter screen 4-3.The inlet pipe
2 are used to connect with an evaporator in the one end in 1 outside of gas-liquid separator shell, and the outlet pipe 3 is in 1 outside of gas-liquid separator shell
One end for being connect with a semi-closed compressor.
Referring to Fig. 1-Fig. 2, in the semi-closed compressor group using permanent magnet frequency conversion motor, the low-temp low-pressure with iron filings
Gas-liquid two-phase cold-producing medium enters inlet pipe 2 by evaporator, enters 1 internal cavity of gas-liquid separator shell, liquid by inner port 2-1
