The invention provides a performance testing device for an engine respirator. The performance testing device comprises a mechanical loading system, a pressure loading system, a temperature loading system and a control system. The mechanical loading system is mainly composed of a servo motor, a simulated crankcase and a simulated crankshaft. The servo motor is connected with the simulated crankshaft in the simulated crankcase. The pressure loading system is mainly composed of an air compressor, a voltage stabilizing chamber, a pressure regulating valve and a pressure sensor. The air compressor,the voltage stabilizing chamber and the pressure regulating valve are serially connected with the simulated crankcase. The temperature loading system is mainly composed of a heating coil and a temperature sensor. The performance testing device has the following advantages of accurately simulating parameters such as exhaust gas pressure, machine oil temperature and crankshaft rotating speed of thecrankcase in different working conditions, truly reflecting the actual working condition of the respirator, simulating the engine crankcase environments with different number of cylinders through changing non-standard crankshafts, and realizing relatively high versatility.
Description
technical field [0001] The invention belongs to the technical field of engine breather design, and in particular relates to a performance test device for an engine breather. Background technique [0002] The breather is a key component of the engine crankcase ventilation system, which plays an important role in ensuring the safe operation of the engine. Poor performance or poor matching of the respirator will lead to serious oil leakage from the respirator, high oil consumption, high exhaust gas pressure in the crankcase, etc., which will seriously affect the performance of the engine. In addition, the poor exhaust gas exhaust of the crankcase will also cause the moisture in the exhaust gas to make the lubricating oil appear white, which will affect the lubrication of various components, accelerate local wear, and affect the service life of the engine. Therefore, the design and matching of respirators are more and more valued by designers. In order to accurately evaluate t...
