Lubricating oil water content exceeding the standard alarm device

Abstract

The invention provides a warning device for lubricant with over-standard water content. The device mainly comprises a capacitance sensor, a guard grating oscillation circuit, a singlechip computer, a four-digit display and a voice alarm, wherein the capacitance sensor is inserted at the bottom of a lubricant tank, and the singlechip computer and a secondary meter are arranged on a distribution disc in a duty room; the singlechip computer is a singlechip computer in a AT899C5R series which contains a 8KR0M 256-bite random-access memory (RAM) and can directly drive a light emitting diode (LED); the capacitance sensor is an HS1100 capacitance sensor, and a water-content signal detected by the capacitance sensor side is converted into a square signal by an NE555 oscillator of a guard grating, and the square signal is transmitted to a 16-bit binary counter of the singlechip computer; and pulse signals are recorded regularly and stored in an internal buffer zone, are subject to digital filter sectional linear correction and water-content level calibration, and are transmitted to the display for displaying and to the voice alarm for alarming. The warning device has the advantages of simple circuit, sensitive response and reliable operation, and ensures safe operation of a high-pressure injection pump.

Description

technical field [0001] The invention relates to an alarm device for excessive water content in lubricating oil of a high-pressure water injection pump. Background technique [0002] Good lubrication of equipment is the fundamental guarantee for the continuous operation of high-pressure water injection pumps. Most of the water injection pump bearing bushes in centrifugal high-pressure water injection pump stations adopt forced lubrication. The lubrication system is mainly composed of lubricating oil tanks, lubricating oil pumps, and cooling filters. Packing leakage, cooling filter perforation and other reasons lead to a large amount of water entering the lubricating oil tank, resulting in serious emulsification and deterioration of lubricating oil, resulting in equipment damage. A large amount of water enters the lubricating oil tank, which can only be detected visually due to serious emulsification and discoloration; a small amount of water enters the oil tank and cannot be ...

A large amount of water enters the lubricating oil tank, which can only be detected visually due to serious emulsification and discoloration; a small amount of water enters the oil tank and cannot be detected in time

Replacement of deteriorated lubricating oil requires the entire station to stop production, seriously affecting the smooth injection of water injection in the entire mine
