Movable kerosene fuel filling sledge

Abstract

The invention relates to the technical field of rocket kerosene filling, in particular to a movable kerosene fuel filling sledge which comprises a container tank car and a 20-inch container type chassis. According to the movable kerosene fuel filling sledge, a plurality of rented kerosene tank cars with pumps are used for replacing conventional kerosene cars and on-site pump trucks, and a vehicle-mounted quantitative filling skid is used for replacing on-site filling pipelines, so that the one-time investment cost is reduced; the filling sledge comprises a flow regulating valve, an emergency cut-off valve, a mass flow meter, a pressure transmitter and other valve instrument assemblies, and the filling task can be safely and quantitatively completed; the quantitative filling skid chassis is designed according to the mounting form of a 20-inch container and can be conveniently mounted on a container trailer, the maneuverability of the pump truck and the quantitative filling truck is good, a launching site is saved, and transition is facilitated; compared with outdoor arrangement, the vehicle-mounted filling skid is good in storage condition, easy to maintain and longer in service life.

Description

technical field [0001] The invention relates to the technical field of rocket kerosene filling, in particular to a mobile kerosene fuel filling skid. Background technique [0002] Liquid oxygen and kerosene are economical fuel combinations for a new generation of launch vehicles. At present, the commonly used rocket kerosene filling scheme in China is shown in the following diagram: the launch site purchases a filling pump truck that meets the requirements of filling efficiency, and pressurizes the medium in the kerosene tank truck through the pump truck, according to the initial small flow rate → large flow rate → final The filling operation of the rocket fuel tank is completed in three processes with small flow rate. [0003] This filling method is mature and rich in filling experience, but the purchase cost of the filling pump truck is high, the pump failure rate is high, the scope of application is very limited, and the operation is inconvenient. Therefore, the market n...
