Description
Technical field
The locomotive pressure device pressurize filtering system that the present invention is a kind of has the memory self-checking function belongs to the lubricated control technique of pressurized machine field.
Background technique
Diesel engine of locomotive use pressurized machine ubiquity rate of fault is high, the broken situations such as many of repairing of facing of machine, the pressurized machine rate of fault accounts for more than 30% of locomotive failure rate, leak as oil sealing, carbon distribution is dead, burn bearing, sweep thorax and the series of problems such as blade breaks, impeller grazing housing usually occur, these problems are perplexing transportation department for many years always, become a difficult problem that deeply worries about of transportation department; Manufacturer has carried out repeatedly rectification for this situation, and still, because the pressurized machine predecessor is that boats and ships are used, in the face of special structure and the Environmental Conditions of locomotive, its deficiency and shortcoming are more and more obvious, and this safe handling to locomotive has caused very large hidden danger.
Analyze the common problem of their defectives, find that the defective that exists is: locomotive pressure device rotating speed is that 24000rpm is many, in order to solve the problem of rotor critical speed, have to adopt flexible shaft, thereby must adopt sliding bearing, and in order to keep higher empty boasting rotating speed, its internal clearance just requires a little bit smaller, the fit up gap of its floating ring internal diameter and main shaft is only 0.01-0.032mm, like this, will be higher to the required precision of manufacturing, and also harsher to the requirement of service condition, the turbidity test of machine oil especially; And at present the lubricant oil that uses of diesel engine of locomotive pressurized machine and diesel engine used be same machine oil, its turbidity test are difficult to reach this requirement (boats and ships sail on the water, and environment is very little to the dustiness of machine oil), the cleaning that improves machine oil is particularly important.
the pressurized machine lubricating oil is provided by the diesel engine oil pump, when diesel engine of locomotive is shut down suddenly, machine oil adverse current in pipeline is returned diesel engine oil pan, producing pressurized machine end oil pressure reduces suddenly, but the pressurized machine short-term also is in the high speed rotating state, at this moment, very easily cause and damage pressurized machine because of the bearing oil starvation, the pressurized machine oil seal structure is weaker, be easy to occur oil leakage fault, the engine oil pressure fluctuation is also a key factor that forms the oil sealing leakage of oil on the other hand, the oil sealing leakage of oil is a main aspect that causes the broken fault of pressurized machine machine, due to above reason, cause in actual using process, be very easy to occur because of the bearing calcination, carbon deposit, dead supercharger rotor etc., and then cause the phenomenon of accident of locomotive defect frequently to occur.
Summary of the invention
The present invention has overcome the deficiency that prior art exists, and provides a kind of and can realize that pressurized machine fuel feeding oil pressure monitor and have a pressurized machine fuel feeding self-checking system of remembering prompting function.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of locomotive pressure device pressurize filtering system with memory self-checking function, the pressurized machine oil supply system mainly is made of main lubricating oil pump, filter cleaner and pressurized machine, be communicated with by oil pipe between the filler opening of Oil gallery delivery side of pump and filter cleaner, the oil outlet of filter cleaner is communicated with by reduction valve with the lubricating pipe entrance of pressurized machine, and the lubricating pipe outlet of pressurized machine is communicated with fuel tank; The filler opening place of described filter cleaner and oil outlet place are equipped with respectively the first pressure transducer that detects the filler opening oil pressure and the second pressure transducer that detects the hydraulic fluid port oil pressure, the signal output part of described the first pressure transducer and the second pressure transducer all is connected with the input port of cpu chip, and described cpu chip is connected with and shows prior-warning device and storage.
On oil pipe between the filler opening of described Oil gallery delivery side of pump and filter cleaner, flowmeter is installed, the signal output part of described flowmeter is connected with the input port of cpu chip.
Be connected with accumulator on oil pipe between described filter cleaner and reduction valve, be provided with safety check on the oil pipe at filter cleaner oil outlet place, stop fluid to pass back into filter cleaner.
Described filter cleaner is two filter cartridge constructions.
The present invention compared with prior art has following beneficial effect.
One, the present invention detects by the oil pressure to filter cleaner filler opening and oil outlet, reach the monitoring to pressurized machine fuel feeding situation, and can remind trainman's fault message by acoustic-optic alarm, can notify the attendant in the very first time that fault occurs, improved the sensitivity of system, avoid the further expansion of fault, increased the reliability of system; Whole apparatus structure is simple, and the element cost is lower.
Two, the present invention is equipped with flowmeter on the oil pipe between the filler opening of Oil gallery delivery side of pump and filter cleaner, the flowmeter monitoring is by the flow of the fluid of filter cleaner, when flow reaches certain value, filter cleaner has reached specified working life, and remind the trainman in time to change filter cleaner by acoustic-optic alarm, the overburdening of the filter cleaner of avoiding is used, and has further improved the reliability of system.
Three, the present invention has increased accumulator and safety check in the lubricant oil oil feeding line of pressurized machine; the charge oil pressure of pressurized machine is slowly reduced; the fault that the pressurized machine bearing that has caused when having avoided diesel engine of locomotive to shut down suddenly produces because of oil starvation; adopt the filter cleaner of two filter cartridge constructions to improve filtering precision; increased pollutant holding capability; extend the Cleaning period, improve the reliability of filtering, be unlikely to occur pressurized machine the phenomenon of excessively heated axle occurs because of oil starvation.
