Description

Technical Field

[0001] This utility model relates to the field of compressor lubrication system testing technology, specifically a device for simulating and evaluating the risk of compressor oil deposition and blockage in the return oil line. Background Technology

[0002] The lubrication system of air compressors (such as screw and reciprocating types) is crucial for the stable operation of the equipment. During the circulation process, some oil mist that is not completely separated from the air in the oil-air separator needs to be returned to the main unit for recycling through the return oil line.

[0003] However, in actual operation, the return oil pipeline often gets blocked due to oil deposits and gum deposits, which prevents the oil from flowing back to the main unit normally. Key components such as bearings and screws suffer from dry friction due to lack of lubrication, which can cause abnormal wear, high-temperature sintering, or even jamming in a short period of time, seriously affecting the performance and lifespan of the equipment.

[0004] Currently, there is no device to simulate this process, which prevents users from effectively assessing the risk of deposits and blockages in different compressor oil lines. Utility Model Content

[0036] The components include: 1. Cylindrical glass oil tank; 2. Test tube; 3. Oxygen conduit; 4. Metal catalytic coil; 5. Silicone oil; 6. Polyethylene tube; 7. Glass stopper; 8. Conical flask; 9.

Detailed Implementation

[0037] In this experimental example, by simulating on-site operation, the pressure difference across the return oil pipeline was measured, and deposits were collected and weighed to determine the degree of blockage. The equipment used to implement this process includes... Figure 1 As shown, this embodiment provides a device for testing the anti-clogging performance of compressor oil return pipe, which includes an imitation oil vapor evaporation component A and an imitation condensation return oil component B;

[0038] Among them, the simulated oil vapor evaporation component A is used to simulate the oil vapor evaporation process after the oil is running in the machine; the simulated condensation return oil component B is used to simulate the process of the evaporated oil vapor condensing through the return oil pipeline.

[0039] The specific structure is as follows:

[0040] The simulated oil and gas volatilization component A includes a test tube 2, a test tube heating device 1 (i.e., a constant temperature oil bath 1), a gas inlet pipeline (i.e., an oxygen conduit 3), and an oil and gas volatilization channel (i.e., a return pipe 14).

[0041] The test tube 2 has a sealing element at the opening, namely, a glass stopper 7;

[0042] The constant temperature oil bath 1 is filled with silicone oil 5 (that is, the structure of a traditional constant temperature oil bath). The heating effect is achieved by heating the silicone oil 5. The temperature control range is 30℃-150℃. In order to improve the heat preservation effect, a heat insulation cover 15 is installed at its opening. The test tube 2 is upright in the oil bath 1 through the circular opening of the heat insulation cover. That is, the test tube 2 passes through the heat insulation cover 15, with one end extending into the constant temperature oil bath 1 and the other end located on the outer viewing side of the heat insulation cover 15.

[0043] The first end of the oxygen conduit 3 passes through the glass stopper 7 and enters the interior of the test tube 2, and the second end is connected to the gas supply device. In this experimental example, the gas supply device is an oxygen cylinder. The specific installation method is that the glass tube 3 is directly inserted into the polyethylene tube 6, and the other end of the polyethylene tube 6 is connected to the oxygen cylinder, thereby achieving the effect of passing oxygen into the oxygen conduit 3.

[0044] The oxygen conduit 3 enters the test tube at one end, reaching or near the bottom of the test tube, thereby forming a uniform airflow and promoting the full evaporation of the oil.

[0045] The portion of the oxygen conduit 3 that enters the test tube is wholly or partially wrapped with a metal catalytic coil 4.

[0046] The first end of the return pipe 14 passes through the glass stopper 7 and enters the interior of the test tube 2, and the second end is connected to the simulated condensation oil return assembly, so that the volatilized oil and gas are introduced into the simulated condensation oil return assembly to achieve condensation recovery.

[0047] The end of the reflux tube 14 that enters the test tube is suspended in the air, close to the lower end face of the sealing element.

[0048] The simulated condenser oil return assembly B includes an oil return pipe 11, a condenser 10, and an oil return receiver 9.

[0049] The return oil pipe 11 is made of transparent borosilicate glass. Its first end is connected to the second end of the return pipe 14 through a three-way valve 12A to receive volatile oil and gas from the simulated oil and gas evaporation component. During use, it is arranged at an angle. The tilt angle of the return oil pipe can be adjusted by changing the three-way valves at different angles, which can simulate the high and low flow rate conditions of the actual return oil pipe. In addition, the structure is segmented and detachable, which is convenient for installation and carrying. Moreover, the carbon deposition process and carbon deposition area on the pipe wall can be observed in real time during the experiment. After the experiment, the pipeline is disassembled and the solid deposits in the return oil pipeline are weighed.

[0050] The second end of the return oil pipe 11 is connected to the first end of the condenser 10 via a three-way valve 12B.

[0051] The second end of the condenser 10 is connected to the oil return receiver 9;

[0052] The end of the oil return receiver 9 is connected to a conical flask 8 for collecting the returned oil. After the test is completed, the weight of the recovered oil is determined by weighing.

[0053] To measure the pressure difference across the return oil line, pressure sensor 13A is connected to the third port of three-way valve 12A, and pressure sensor 13B is connected to the third port of three-way valve 12A. This facilitates recording the changes in pressure difference sensor readings before and after the test.

[0054] The function and effect of this embodiment:

[0055] 1. Direct observation of the carbon deposition process through transparent tubing makes the experimental process and results more intuitive;

[0056] 2. By replacing the tee with different specifications and adjusting the tilt angle of the return oil pipe, the high and low flow rate conditions of the actual return oil pipe can be simulated, and the evaluation of different working conditions can be realized.

[0057] 3. By measuring the pressure difference in the return oil pipe, the anti-clogging performance of the oil can be quantitatively evaluated;

[0058] 4. Short testing cycle and lower cost than on-board testing.
