Regulating control mechanism for high-vacuum oil filling equipment and oil filling speed regulating method thereof

Abstract

The invention provides a regulating control mechanism for high-vacuum oil filling equipment. The mechanism comprises a speed limiting rod, a guide control rod, a regulating mechanism and a sliding sealing mechanism, wherein the regulating mechanism controls the throttling end of the speed limiting rod by controlling the guide control rod so as to change the cross sectional area, which is suitablefor oil to pass through, of an oil outlet and control the oil filling speed of the oil outlet. The invention also provides an oil filling speed regulating method for filling oil into an inertia element by using the regulating control mechanism. In the method, the regulating mechanism is operated, the throttling end of the speed limiting rod is controlled by controlling the guide control rod, so that the cross sectional area, which is suitable for the oil to pass through, of the oil outlet of an oil storage device is changed and the oil filling speed of the oil outlet is controlled. The regulating control mechanism for the high-vacuum oil filling equipment and the oil filling speed regulating method thereof can accurately and slightly regulate the oil filling speed, ensure the air tightness of a vacuum chamber, reduce the occupied space of the equipment and improve oil filling efficiency.

Description

technical field [0001] The invention relates to the field of instruments and meters (analytical instruments), in particular to an adjustment control mechanism for high vacuum oil-filled equipment and an oil-filled speed regulating method for assisting in oil-filling inertial elements. Background technique [0002] In recent years, with the development of aviation, navigation industry and military technology, my country's demand for inertial sensing components and inertial navigation components, such as gyroscopes and accelerometers, has increased rapidly. These inertial components need to be exhausted and filled with oil (that is, oily substances such as insulating oil are injected into their inner cavities) to ensure their normal operation. [0003] The above oil filling process needs to be carried out in a high vacuum environment. This is because if the oil filling is performed in an atmospheric environment, the oil injected into the inertial element will contain a large n...
