Abstract
The utility model relates to the technical field of lithium battery energy storage, specifically relates to a liquid supplementing device, the liquid supplementing device includes manual pump, it includes pump body, the pump cavity formed in the inside of pump body and the suction port and the liquid injection port that communicate pump cavity with outside, the suction pipeline, its water inlet side is connected to outside water source, and the water outlet side is connected to the suction port, the liquid injection pipeline, its water inlet side is connected to the liquid injection port, and the water outlet side is connected to the liquid supplementing equipment, the pressure gauge is located on the liquid injection pipeline, the exhaust valve is located on the water outlet side side of pressure gauge and is connected to the liquid injection pipeline. Liquid supplementing device runs through manual pump operation, and the pressure gauge is used with manual pump, when the real -time liquid pressure that pressure gauge detects approaches threshold value, the operator can control the manual pump and make the flow rate of liquid slow down, and the liquid of slow -speed approaches the state of static pressure. The liquid supplementing device does not need external power supply to supply electric energy, can avoid the risk of electric shock, is suitable for a variety of scenes indoors and outdoors, simple operation, and the liquid supplementing amount is accurate.
