Problems solved by technology

The inspection cycle is long. During the inspection period, cleaning needs to be continued, and the cleaning work cannot be stopped in time when the standard is met, resulting in waste of hydraulic oil. In addition, it also causes the delivery cycle of the shipyard to be extended.

Embodiment Construction

[0014] In the present invention, the online cleaning method of marine hydraulic pipeline cleaning oil is as follows: figure 1 , as shown in 2,

[0015] At first the sampling point is set, and in the present invention, the sampling point is set before the entrance of the pipeline cleaning pump station on the main oil circuit 1 of the ship pipeline; a detachable transparent sampling bypass is set at the sampling point, and the transparent sampling bypass The two ends of the tank are respectively connected to the main oil circuit, and a capacitive sensor module and a photoelectric sensor module connected to the signal processing system are arranged on the transparent sampling bypass.

[0016] As a more specific implementation of the present invention:

[0017] Signal processing system 12 adopts AT89C2051 single-chip microcomputer, and forms signal processing system with peripheral interface circuit MAX1109 type A / D converter, serial port and peripheral chip 74LS164.

[0018] Th...

Abstract

The invention relates to a marine hydraulic pipeline cleaning-oil online cleaning method. The marine hydraulic pipeline cleaning-oil online cleaning method is characterized in that a sampling point is arranged at the entrance, to a pipeline cleaning pump station, of a main oil circuit of a shipping pipeline; a detectable transparent sampling bypass is arranged at the sampling point, and a capacitance sensor module and a photoelectric sensor module are arranged on the transparent sampling bypass; the shipping pipeline is wholly and circularly cleaned by the aid of hydraulic oil; sampling detection is performed in the manner that during the sampling process, flow rate of the hydraulic oil is controlled to be 6-10m / s, moisture in the hydraulic oil is detected through the capacitance sensor module, scrap iron and oxide impurities in the hydraulic oil are detected through the photoelectric sensor module, calibration display of cleanliness of cleaning oil is performed through processing of a signal processing system, the preset national standard value is compared, and on-off of the pipeline cleaning pump station is controlled. Therefore, cleaning schedule can be fed back to a working staff in time, consumption of the cleaning oil is reduced, cleaning circle is shortened, construction time can be reasonably arranged, and working efficiency can be provided.

Description

technical field [0001] The invention relates to a method for detecting the cleanliness of cleaning oil, in particular to an online cleaning method for marine hydraulic pipeline cleaning oil. Background technique [0002] my country's shipbuilding industry has always paid too much attention to shipbuilding, while ignoring the research and development and manufacturing of ship supporting facilities. The lack of research and development of supporting facilities has restricted the development of my country's shipbuilding industry. The value of ship supporting products accounts for about two-thirds of the total value of ships, and plays a pivotal role in the shipbuilding industry. Improving the international competitiveness of the ship supporting industry is a necessary condition for building a world-class shipbuilding power. [0003] As we all know, the fuel, lubricating oil and hydraulic piping systems must be oiled and cleaned before being installed on board. The oil feeding a...
