Two-wire centralized lubrication system

Abstract

The invention relates to a two-wire centralized lubrication system which comprises an electric lubricant pump, a lubricant pump motor, a fuel tank and a control cabinet, wherein a liquid level sensor is arranged in the fuel tank, and a refueling pump is embedded in the fuel tank; the refueling pump is connected with the electric lubricant pump, and the electric lubricant pump is provided with a safety valve and a solenoid directional valve; a pipeline for connecting the safety valve and the solenoid directional valve is provided with a pressure gage, the solenoid directional valve is connected with a longitudinal main oil supply pipe, and the longitudinal main oil supply pipe is provided with a grease filter and connected with a horizontal main oil supply pipe; one side of the horizontal main oil supply pipe is connected with a two-wire distributor A and a two-wire distributor C, the horizontal main oil supply pipe is connected with a differential pressure switch by the two-wire distributor A, and the differential pressure switch is connected with a two-wire distributor B; and the other side of the horizontal main oil supply pipe is connected with a two-wire distributor D and a two-wire distributor E, the control cabinet is connected with a remote monitoring computer, and the remote monitoring computer is connected with an alarm. The two-wire centralized lubrication system has the advantages that because lubricating points are distributed widely, a plurality of lubricating points can be lubricated; and meanwhile, the two-wire centralized lubrication system can be monitored remotely.

Description

technical field [0001] The invention relates to a centralized lubricating system, in particular to a two-line centralized lubricating system. Background technique [0002] System piping is an important link in the design of the dry oil centralized lubrication system. The reasonable layout of the piping system and the correct selection of connection methods can ensure the normal operation of the entire system and reliably supply lubricant to each lubrication point. Two-line centralized lubrication system is mainly composed of lubrication pump, reversing valve, two main oil supply pipelines, branch pipelines, two-line distributor, differential pressure switch (pressure control valve) and pipeline accessories. The lubricating grease output by the lubricating pump passes through the reversing valve and is alternately transported by the two main oil supply pipelines to the inlet of the double-line distributor. After quantitative distribution by the double-line distributor, it is ...

AI Technical Summary

Problems solved by technology

The lubricating grease output by the lubricating pump passes through the reversing valve and is alternately transported by the two main oil supply pipelines to the inlet of the double-line distributor. After quantitative distribution by the double-line distributor, it is sent to each lubrication point. This lubrication system only has the function of on-site lubrication. , in the case of unattended, in case of special circumstances, the lubrication of each point cannot be carried out smoothly
