Water content of lub oil analyzer for towboat rudder propeller

Abstract

This invention relates to lubricating oil water content tester of towboat rudder quant device. It includes water content sensor module, intelligence transmitter module. The sensor includes that standard signal generated by signal generator is attenuated through bacillary probe and changed into electrical signal that opposite to water content of the testing oil. The bacillary probe is connected to linear circuit through amplifier circuit and rectification filter circuit. The intelligence module includes temperature compensating circuit, the circuit is separately connected to LCD display, RS232 interface, operation keyboard through A / D switching and CPU. The volume of the device is small, precision is high, reliability is good, and it is convenient to carry. The bind that normal lubricating oil water content test must done in lab is conquered, the test can be done at any time at spot. It is propitious to towboat rudder quant device lubricating oil system and any other oil water content detecting system, and it can also be extended to diesel oil water content detecting, so it has wide market development prospect.

Description

technical field [0001] The invention relates to a tester, in particular to a lubricating oil moisture tester for a tugboat rudder paddle device. Background technique [0002] With the continuous development of the port industry, the tugboat's operating volume is increasing, and the operating range is expanding outward. All kinds of tugboats mainly operate in the harbor and offshore shallow water areas, where there are many fishing nets and floating objects, and the waterway is complicated. During the sailing operation of the tugboat, the rudder propeller is easily damaged and entangled by the sundries, causing damage to the stern shaft seal and leakage, resulting in excessive moisture in the lubricating oil of the rudder propeller transmission device, which seriously affects the lubrication performance. If the performance index of lubricating oil is lower than the standard, mainly because the water content exceeds the standard, it will seriously damage the transmission mech...

AI Technical Summary

Problems solved by technology

The damage caused by water largely depends on the length of its existence and the degree of emulsification. For the situation where the water content of the lubricating oil of the rudder propeller transmission device exceeds the standard, generally experienced engine management personnel can only make a rough judgment based on experience.

Conventional lubricating oil moisture detection methods include on-site experience method. Through the summary of on-site experience, the water content is roughly judged, and the error is large. According to 1, visual method 2, sound method 3, test paper method, or use laboratory analysis to collect oil samples and submit them to the experiment Laboratory professionals to conduct analysis, the analysis accuracy is high, but the analysis period is long and the cost is high
