Self-propelled high-pressure nitrogen filling equipment

Abstract

The invention discloses a self-propelled high-pressure nitrogen charging device. The self-propelled high-pressure nitrogen charging device comprises an upper-layer vehicle frame, a middle-layer vehicle frame and a lower-layer vehicle frame. The lower-layer vehicle frame is provided with anti-explosion lithium batteries for supplying electricity. The middle-layer vehicle frame is provided with a plurality of nitrogen cylinders. The upper-layer vehicle frame is provided with a gas valve device, a pressurization device, a high-pressure gas bomb, a hydraulic device and a plurality of pipe coiling devices. The hydraulic device comprises an oil tank, a motor, an oil pump, a filter, an overflow valve and a pilot operated directional control valve. The pressurization device comprises an oil cylinder barrel, high-pressure air cylinders arranged at the two ends of the oil cylinder barrel, a piston arranged in the oil cylinder barrel, and high-pressure plungers connected with the two ends of the piston. The nitrogen cylinders are connected with the pressurization device through the gas valve device. The output end of the high-pressure gas bomb is connected with a gas inlet connector of one pipe coiling device through a reducing valve. The self-propelled high-pressure nitrogen charging device is compact in structure, convenient to operate and capable of carrying out nitrogen charging at multiple positions simultaneously, thereby substantially improving the nitrogen charging efficiency.

Description

technical field [0001] The invention relates to the technical field of high-pressure nitrogen filling equipment, in particular to a self-propelled high-pressure nitrogen filling equipment. Background technique [0002] Nitrogen filling vehicle is a kind of nitrogen filling equipment with hydraulic pressure as the power source. It consists of four parts: hydraulic device, nitrogen booster device, instrument control system, and movable body. It can pressurize low-pressure nitrogen to 10- The pressure range of 65MPa solves the problem that the accumulator or other high-pressure containers cannot be filled with nitrogen when the nitrogen cylinder pressure is insufficient. The principle of utilizing the nitrogen-charging vehicle to inflate accumulators and other equipment can be referred to the patent application number 97229429.5 "nitrogen-charging vehicle". [0003] Nitrogen charging vehicles can be applied to: 1. Gas boosting: such as accumulators, aircraft tires, high-pressu...
