Description
Technical field
The utility model is related to a kind of piston-cylinder liner component wear system for measuring quantity, in specifically a kind of diesel engine
The real-time measurement system of piston-cylinder liner wear extent.
Background technology
The state of wear of internal combustion engine-cylinder sleeve is to determine one of principal element of diesel engine service life.Due to cylinder
The irregular wear of wall causes the high temperature and high pressure gas in cylinder to leak into crankcase, causes the pressure of gas and temperature in crankcase
Degree is raised, and its wear extent is bigger, and gas leakage is more, and in crankcase, air pressure is higher, accordingly, it would be desirable to the abrasion to piston-cylinder liner
Amount is measured, and is all traditionally to piston-cylinder liner by indentation method, radioisotope method, iron spectrometry and spectroscopic methodology etc.
Abrasion amount measuring, said method cannot meet the real-time measurement request of wear extent, and the capacitance measurement rule for adopting later has biography
Sensor measuring point quantity is more, the shortcomings of measurement apparatus are complicated.
Content of the invention
Technical problem to be solved in the utility model is to provide one kind and can pass through monitoring leakage gas in crankcase
Pressure carry out the wear condition of monitoring, diagnosing piston-cylinder liner, and then predict the piston-cylinder liner wear extent of the residual life of cylinder
Real-time measurement system.
In order to solve above-mentioned technical problem, the real-time measurement system of piston-cylinder liner wear extent of the present utility model, including peace
The gas pressure sensor of crankcase side is mounted in, gas pressure sensor connects one is used for collecting crankshaft loading pressure
The data acquisition equipment of data, gas sensor can be detected and leak into the pressure of gas the data letter by detection in crankcase
Breath is transferred to data acquisition equipment, and the data acquisition equipment connects a computer, data acquisition through an interface circuit
The data information transfer for collecting can be processed to computer and by computer by equipment to the information data for receiving, institute
State computer and be connected with the output equipment for being exported to information data.
The output equipment includes sound equipment and/or LCDs.
The data acquisition equipment and the computer connected by interface circuit are all positioned in central station of floating dock.
The side of the crankcase is provided with explosion proof door, and the gas sensor is arranged on the one of crankcase by explosion proof door
Side.
The buzzer for reporting to the police is connected with the computer.
After using above-mentioned structure, due to the gas being connected installed in crankcase side and with data acquisition equipment for arranging
Pressure sensor and the computer being connected with data acquisition equipment, thus can detect barrel wear by gas pressure sensor
Leak into the pressure of the high temperature and high pressure gas in crankcase and data acquisition equipment and computer can be passed through, realize signal
Collection, the transimiison analysis of data and process such that it is able to complete to diesel cylinder liner abrasion detection and can pass through at computer
The residual life of cylinder is predicted after reason analysis.
Description of the drawings
Schematic diagrams of the Fig. 1 for the real-time measurement system of the utility model piston-cylinder liner wear extent；
Flow charts of the Fig. 2 for the real-time measurement system of the utility model piston-cylinder liner wear extent.
Specific embodiment
With reference to the accompanying drawings and detailed description, the real-time measurement system to piston-cylinder liner wear extent of the present utility model
System is described in further detail.
As illustrated, the real-time measurement system of piston-cylinder liner wear extent of the present utility model, including installed in crankcase 1
The gas pressure sensor 2 of side, the side of crankcase 1 are provided with explosion proof door 7, and gas sensor 2 is arranged on by explosion proof door 7
The side of crankcase 1, gas pressure sensor 2 connect a data acquisition for being used for collecting crankshaft loading pressure data and set
Standby 3, there is data acquisition module in data acquisition equipment 3, as seen from the figure, when the high temperature and high pressure gas in cylinder leak into bent axle
After case, gas pressure sensor 2 can detect the pressure for leaking into gas in crankcase, and the data information transfer of detection is given
Data acquisition equipment, data acquisition equipment 3 connect a computer 5 through an interface circuit 4, and there are in computer 5 data
Analysis and processing module, data acquisition equipment 3 can by the data information transfer for collecting to computer and by computer to receive
To information data be analyzed process, computer 5 is connected with the output equipment for being exported to information data, and which is concrete
In processing procedure, the data acquisition module in data acquisition equipment is used for arranging carries out A/D turn using frequency, to primary signal
Change；Analysis and processing module in computer is analyzed to gas leakage pressure signal and processes.
Further, described data acquisition equipment 3 and the computer 5 connected by interface circuit are all positioned in collection control
In room 6, it is easy to cabin operator on duty observation cylinder wear situation, described output equipment to include sound equipment and/or LCDs,
The alarm for reporting to the police is connected with computer 5, and described alarm is buzzer, LCDs and alarm output gas
Cylinder wear and tear overrun is reported to the police and shows the information such as cylinder life-span.
Its operation principle is as follows：
Gas sensor measurement leaks into the pressure of gas in crankcase, gas in data acquisition equipment timing acquiring crankcase
Body pressure data, is connected with computer by interface circuit, realizes that the place to gathered data is realized in the transmission of data, computer
Reason, analysis and judgement, need threshold value first in the process, and barrel wear is more serious, leaks into the gas in crankcase
More, bent axle loading pressure is bigger, if the abrasion standard of cylinder sleeve is m, now corresponding bent axle loading pressure P is to sentence
Disconnected barrel wear threshold value, as shown in Fig. 2 when using, start the analysis and processing module in computer, timing collection and analysis
Data, if cylinder wear amount exceedes the threshold value of regulation, trigger buzzer warning, otherwise make in liquid crystal display screen display cylinder
With the life-span, thus make use of buzzer to realize the exceeded warning of cylinder wear, cylinder sleeve residual life is shown by LCDs.
