Problems solved by technology
[0003] The hydraulic system pressure of civil aircraft is generally 3000PSI-5000PSI. Under this high pressure, it is difficult for ordinary multi-channel hydraulic valves to accurately control the flow of purple oil, and the valve control response time is long, and temperature stratification of purple oil is prone to occur during the mixing process.
Based on the above shortcomings, the commonly used valve adjustment method cannot be used for temperature control and mixing of purple oil.

The invention provides a purple oil temperature control device which comprises a curved tube heat exchanger, a flow temperature detector and a purple oil mixer. The curved tube heat exchanger is connected to a normal temperature oil tank through a hydraulic pump and used for heating normal temperature purple oil to be at the set temperature. The flow temperature detector is connected to the curved tube heat exchanger and used for measuring the flow and temperature of the heated purple oil. The purple oil mixer is connected to the flow temperature detector and connected to a low temperature oil tank through a hydraulic pump. The purple oil mixer adjusts the flow of the low temperature purple oil according to the flow and temperature, detected by the flow temperature detector, of the heated purple oil, so that the mixing ratio of the high temperature purple oil and the low temperature purple oil is controlled, and the temperature of the output purple oil is controlled.
Description
technical field [0001] The invention relates to a temperature control device for purple oil under high pressure. Background technique [0002] Hydraulic actuator is a driving device widely used in civil aircraft. Aviation purple oil is used as the driving fluid, and its dynamic performance is greatly affected by the temperature of the working purple oil. At present, during the use of the actuator, it is generally only required that the temperature of the purple oil be within a certain allowable range, and the influence of temperature changes in the work of the purple oil is rarely mentioned. Therefore, by inputting purple oil with temperature change, and then conducting dynamic response test of variable temperature frequency sweep on the actuator, the change of dynamic characteristics of the actuator can be studied. [0003] The hydraulic system pressure of civil aircraft is generally 3000PSI-5000PSI. Under this high pressure, it is difficult for ordinary multi-channel hydr...
