Commercial vehicle air dryer oil filtering efficiency test device and method thereof

Abstract

The invention discloses a commercial vehicle air dryer oil filtering efficiency test device and a method thereof. The device comprises an air source, a pressure reducing valve, an air storage tank, afirst pressure gauge, a stop valve, a flow regulation display device, a compressed air heater, an atomized lubricator, an air dryer, a simulated air consumption device, a temperature detection displaydevice, a temperature-resistant compressed air oil content detection display device, a second pressure gauge and a compressed air oil content detection display device. A first four-way joint is arranged between the atomized lubricator and the air dryer; and a second four-way joint is arranged between the air dryer and the simulated air consumption device. According to the commercial vehicle air dryer oil filtering efficiency test device and method, the air inlet flow, the pressure, the temperature and the oil content of the air dryer can be controlled and adjusted according to test requirements, the oil content of compressed air passing through the air inlet and the air outlet of the air dryer is detected in real time, and the accurate air dryer oil filtering efficiency is obtained; and the oil filtering performance of the product is effectively verified.

Description

technical field [0001] The invention belongs to the technical field of auto parts testing, and in particular relates to a commercial vehicle air dryer oil filter efficiency test device and a method thereof. Background technique [0002] Air dryer oil filtration efficiency test device, including standard oil blowing air compressor, dryer, oil collection device, air storage tank, use the method of weighing the balance or measuring the volume of the measuring cup to test the oil collected by the oil collection device, which can only be compared The difference in the oil filtering effect of the dryer, the test cost is high, the test efficiency is low, and the error of the test test value is large. [0003] In addition, a special standard oil blowing air compressor is required. After the air compressor itself is worn out, the amount of oil blowing is not suitable for control, and the use cost is high; the oil collected through the oil collection device at the outlet of the dryer ...

[0002] Air dryer oil filtration efficiency test device, including standard oil blowing air compressor, dryer, oil collection device, air storage tank, use the method of weighing the balance or measuring the volume of the measuring cup to test the oil collected by the oil collection device, which can only be compared The difference in the oil filtering effect of the dryer, the high cost of the test, the low test efficiency, and the large error of the test test value

[0003] In addition, a special standard oil blowing air compressor is required. After the air compressor itself is worn out, the amount of oil blowing is not suitable for control, and the use cost is high; the oil collected through the oil collection device at the outlet of the dryer is weighed with a balance or measured with a measuring cup. The method can only compare the difference in the oil filtration effect of different configurations of drying tank dryers, and obtain the relative value of the oil filtration efficiency, but cannot accurately obtain the absolute value of the oil filtration efficiency
