Abstract

The invention relates to the technical field of LNG / L-CNG filling stations, aims to solve the problems of low working efficiency and slow filling speed of existing LNG / L-CNG supercharging devices, and provides an LNG / L-CNG hydraulic pressure boosting installations and filling stations. The LNG / L‑CNG hydraulic booster device includes the first hydraulic pump, the second hydraulic pump, the L‑CNG booster cylinder, the LNG booster cylinder, the first directional valve, the second directional valve, the oil tank, the ball valve, and the first hydraulic pump The oil inlet is connected to the oil tank, the pressure oil outlet is connected to the oil inlet of the first directional valve, and the first directional valve is connected to the L-CNG booster cylinder. The oil inlet of the second hydraulic pump is connected to the fuel tank, the pressure oil outlet is connected to the oil inlet of the second directional valve, and the second directional valve is connected to the LNG booster cylinder. The first port of the ball valve communicates with the first communication port between the pressure oil outlet of the first hydraulic pump and the oil inlet of the first directional valve, and the second port of the ball valve communicates with the pressure oil outlet of the second hydraulic pump and the second directional valve The second communication port between the oil inlets. The invention has the beneficial effects of high working efficiency, low energy consumption and fast filling speed.

Description

technical field [0001] The invention relates to the technical field of LNG / L-CNG filling stations, in particular to an LNG / L-CNG hydraulic booster and a filling station. Background technique [0002] LNG / L-CNG hydraulic pressure booster is a device for LNG / L-CNG gas filling station for LNG filling or L-CNG gas filling. [0003] Existing LNG / L-CNG hydraulic pressure boosting devices generally use submersible pumps as the power source, and LNG liquid filling and L-CNG gas filling have the problems of low work efficiency and slow filling speed during use. Contents of the invention [0004] The present invention aims to provide an LNG / L-CNG hydraulic booster to solve the problems of low working efficiency and slow filling speed of the LNG / L-CNG booster in the prior art. [0005] Another object of the present invention is to provide an LNG / L-CNG filling station equipped with the above-mentioned LNG / L-CNG hydraulic booster. [0006] Embodiments of the present invention are ach...
