Ground direct and quantitative filling system and method

Abstract

The invention relates to a ground direct and quantitative filling system and a ground direct and quantitative filling method, which are used for filling an end correction storage container. The ground direct and quantitative filling system comprises a rack, an air channel system, a liquid path system, an electronic control system, a filling tank, an overflow tank, a waste gas treatment device, a filling and draining connector and an electronic scale, wherein the liquid path system, the air channel system and the electronic control system are positioned in the rack and are used for starting working procedures, controlling a valve, monitoring display, controlling a filling amount and filling accuracy and regulating filling speed. The filling method comprises the following steps of: controlling the filling accuracy, controlling filling flow, controlling the filling process, controlling filling time and controlling filling counter pressure. In the ground direct and quantitative filling system and the ground direct and quantitative filling method, the filling accuracy is close to the filling accuracy reached in a quantitative mode of the storage container on a rocket by utilizing technologies of controlling the filling accuracy, the filling flow, the filling process, the filling time and the like, 'one-button' type filling is realized, and the requirement of filling accuracy of the end correction storage container is met.

Description

technical field [0001] The invention relates to a filling technology, in particular to a ground direct quantitative filling system and method that meets the filling accuracy requirements of a finishing tank. Background technique [0002] The propellant filling technology of launch vehicles at home and abroad usually adopts the quantitative method of the storage tank on the arrow to achieve the required high filling accuracy. However, due to the structural limitations of some types of final repair tanks, there is no quantitative device inside, so the required filling accuracy must be achieved by direct quantitative method on the ground, and the filling process, filling speed and filling back pressure must be monitored. automatic control. Since it is difficult to achieve the required filling accuracy by the direct quantitative method on the ground, it is rarely used except for final maintenance and attitude control propellant filling, and there are no reports at home and abro...
