Abstract

The invention discloses a liquid composite spring push-pull type vacuum liquid injection machine and a liquid injection method, comprising a vacuum pump, a vacuum pump solenoid valve, a vacuum quick-change joint, an oil tank, a gas-liquid separator, a high-pressure water pump, a high-pressure water pump solenoid valve, a liquid discharge Solenoid valve; the vacuum pump is connected to the gas-liquid separator, the gas-liquid separator is connected to the solenoid valve of the vacuum pump, and the solenoid valve of the vacuum pump is connected to the vacuum quick-change joint; the bottom of the gas-liquid separator is connected to the drain solenoid valve, and the drain solenoid valve is connected to the oil tank. The upper part of the gas-liquid separator is divided into two cavities, and the two cavities are respectively connected with the vacuum pump and the liquid composite spring. When recovering the medium, the negative pressure and liquid gravity are used to reflow and separate the cavity separation, so as to realize the gas-liquid separate. The invention can realize on-site liquid injection and on-site mobile inspection, realize liquid injection and pressure maintenance and medium recovery, fully separate gas and liquid during medium recovery, prevent the medium from flowing into the vacuum pump, and prevent damage to the vacuum pump.

Description

technical field [0001] The invention relates to the technical field of vacuum liquid injection. Background technique [0002] Liquid compound spring vacuum liquid injection machine is a kind of operation equipment specially provided for liquid compound spring inspection and liquid injection, which can realize liquid injection after vacuum and negative pressure liquid return; It is an indispensable equipment for daily liquid injection, inspection and maintenance. In the current vacuum liquid injection device, the gas-liquid separation is not sufficient during medium recovery, and the liquid is easy to flow back to the vacuum pump, causing failure or even damage to the vacuum pump. There are still some technical problems to be solved in terms of realizing on-site liquid injection and on-site mobile inspection, realization of liquid injection and pressure maintenance, and medium recovery. [0003] In the prior art, the utility model with the application number CN201620904045....
