Centralized lubricating device with low liquid level alarm function

Abstract

A centralized lubricating device with a low liquid level alarm function comprises a grease pump shell, a grease pressing disc, a folding grease bag and a grease box shell, the grease pressing disc is installed in the grease box shell and connected with the folding grease bag, and an grease guide pipe is inserted into a cavity of the folding grease bag through an installation hole in the grease pressing disc and a grease injection hole of the folding grease bag. A spring push plate assembly drives the grease pressing disc to move in the grease box shell, a magnet synchronously moving along with the grease pressing disc is arranged on the peripheral face of the grease pressing disc, a reed switch is arranged at the position, close to an end cover of the grease box shell, of the inner part of the grease pump shell, and the two ends of the reed switch are connected with an alarm circuit through wires respectively. When the grease pressing disc moves to a certain position, the magnetic force of the magnet enables the reed switch to be conducted, the alarm circuit is conducted, and the alarm unit is controlled to output an alarm signal. According to the scheme, the structural composition of the centralized lubricating device is optimized, and when grease in a grease box is about to be used up, a warning system arranged in a vehicle can automatically send out warning information to remind workers to supplement the grease in time.

Description

technical field [0001] The invention relates to the technical field of centralized lubrication, in particular to a centralized lubrication device with a low liquid level alarm function. Background technique [0002] At present, dry oil centralized lubrication technology is mainly used in large vehicles, construction machinery, wind power generation, industrial production and other fields. Its function is to automatically pump grease to the lubricating point through the oil pump to meet the lubrication needs of the corresponding kinematic pair. The centralized lubrication and oil supply system solves the shortcomings of traditional manual lubrication. It can provide regular, fixed-point, and quantitative lubrication during mechanical work, which greatly reduces the wear of parts and greatly reduces the amount of lubricant used. It is environmentally friendly and energy-saving. At the same time, reduce the loss of parts and maintenance time, and finally achieve the best effec...

Problems solved by technology

The current product still has one shortcoming: when the lubricating grease in the oil box is about to be exhausted, it cannot automatically alarm, and it is necessary to manually check whether the grease in the oil box is exhausted; it is easy to cause the problem that the oil box is not replaced in time and affects the lubrication of the whole machine
