Description

Technical Field

[0001] The utility model belongs to the technical field of oil separators, and in particular relates to an oil separator. Background Art

[0002] The oil separator is an auxiliary equipment in the compression refrigeration system. It is usually installed between the compressor and the condenser of the compression refrigeration unit to separate the lubricating oil from the high-pressure refrigerant gas discharged from the compressor.

[0003] It is difficult to control the flow rate or flow rate of the refrigerant gas entering the existing oil separator. When the flow rate of the refrigerant gas is too fast or the flow rate is too large, insufficient oil separation is likely to occur due to the limited separation capacity of the oil separator. Summary of the invention

[0004] The utility model aims to solve the above-mentioned technical problems existing in the prior art and provides an oil separator with a novel structure. The added solenoid valve can accurately control the flow rate and flow rate of the refrigerant gas to adapt to the actual working conditions. The added filter can filter out solid impurities in the oil to prevent the solid impurities from flowing back to the compressor with the oil and causing compressor failure.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An oil separator comprises: a cylinder, an air inlet pipe and an air outlet pipe are arranged on the cylinder, and a U-shaped oil outlet pipe is arranged at the bottom of the cylinder, and is characterized in that: an electromagnetic valve is connected to the air inlet pipe; and a filter screen is arranged at one end of the U-shaped oil outlet pipe extending into the cylinder. The oil separator has a novel structure, and the additional electromagnetic valve can accurately control the flow rate and flow of the refrigerant gas to adapt to the actual working conditions, and the additional filter screen can filter out solid impurities in the oil to prevent the solid impurities from flowing back to the compressor with the oil and causing compressor failure.

[0007] Furthermore, a mounting block is provided on the cylinder body, and a mounting hole is provided on the mounting block. A nail is inserted into the mounting hole to facilitate fixing the whole to a designated position, thereby improving installation convenience.

[0008] Furthermore, an oil level sensor is provided on the air intake pipe. The rod of the oil level sensor extends into the cylinder. An oil inlet hole and a filter mesh sleeve are provided on the rod body. The filter mesh sleeve is located outside the oil inlet hole. The oil level sensor is used to detect the oil level in the cylinder, which is convenient for the staff to flexibly control the oil output according to the oil storage amount, reducing the management difficulty; the filter mesh sleeve can filter out solid impurities in the oil to prevent the solid impurities from clogging the oil inlet hole and affecting the use of the oil level sensor, thereby playing a simple protective role.

[0009] Furthermore, an end plate is provided at the top of the intake pipe, and a flange is provided on the oil level sensor. The flange is fixedly connected to the end plate by bolts, and is reliably fixed, thereby ensuring the installation stability of the oil level sensor, and the sensor is easy to assemble and disassemble, and can be used whenever installed, which is flexible and convenient.

[0010] Furthermore, a sealing gasket is provided between the flange and the end plate. The sealing gasket is in close contact with the flange and the end plate, and the gap is very small, so leakage is not likely to occur there, thereby improving the sealing of the connection between the oil level sensor and the intake pipe.

[0011] Furthermore, the filter screen sleeve is threadedly connected to the rod body through the screw sleeve, which is reliably fixed. The position of the filter screen sleeve on the rod body is variable, ensuring that the filter screen sleeve can cover the oil inlet hole. It is detachable and replaceable, and can be used at any time, which is flexible and convenient.

[0012] Furthermore, the inner wall of the cylinder is coated with an oleophobic layer, which has a good oleophobic effect, so that the inner wall of the cylinder has a good repulsive force on oil molecules, and the oil molecules are not easy to adhere to the inner wall of the cylinder, thereby reducing the residual oil molecules when discharging the oil, and improving the oil return volume and oil return efficiency.

[0013] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0014] 1. The solenoid valve can accurately control the flow rate and flow of the refrigerant gas to adapt to the actual working conditions, avoiding the phenomenon of insufficient oil separation due to the limited separation capacity of the oil separator when the flow rate of the refrigerant gas is too fast or the flow is too large, thus ensuring the separation effect.

[0015] 2. The filter sleeve can filter out solid impurities in the oil to prevent the solid impurities from clogging the oil inlet and affecting the use of the oil level sensor, playing a simple protective role; the position of the filter sleeve on the rod body is variable to ensure that the filter sleeve can cover the oil inlet, and the filter sleeve is removable and replaceable, and can be used at any time, which is flexible and convenient.
