Embodiment
Embodiment one:
As shown in Figure 1, provided a specific embodiment structure principle chart of intelligent multipoint mode centralized lubrication system according to the invention.
Whole system comprises oil station 9 and controller 7; In-line 8 parallelly connected oil supply controllers are passed through to each lubricating point in oil station 9; The oil supply controller is selected solenoid valve 1 for use; Said master controller 7 circuit connect solenoid valve 1 and control its action, are each fuel feeding point fuel feeding by oil station 9 through in-line 8, and the fuel-displaced pipeline in said oil station is provided with pressure controlled valve control oil pressure.The fuel-displaced pipeline in oil station is provided with pressure transducer 10 and is used to detect oil pressure, is serially connected with filter 11 and is provided with pressure controlled valve 12 control oil pressure.
Said controller 7 adopts the PLC programmable controller, is connected with computer 13, can and monitor its working state through computer 13 programmings.
Its relevant work principle is following:
After pressure oil gets into from in-line 8 shown in the figure, respectively to each solenoid valve 1 fuel feeding, when electromagnet get electric after; The promotion electromagnetic valve core is opened, and pressure oil gets into solenoid valve lower piston chamber, shifts piston onto the cavity low order end; Make pressure oil pass through the upper piston chamber and get into oil feed line 4, this moment, pressure oil promoted the lubricant housings that back pressure valve 5 gets into fuel feeding point 6, and displacement transducer 1 is used to detect piston motion in this process; Whenever solenoid valve 1 fuel feeding just often, i.e. lower piston chamber piston motion is when the cavity low order end, displacement transducer 1 detects displacement signal; And convert displacement signal into electrical signal output; The existence of back pressure valve 5 can make and form certain back pressure in the oil feed line 4, and oil feed line 4 directly links to each other with the piston cavity of displacement transducer 2 31, when solenoid valve 1 fuel feeding; Under the effect of oil feed line 4 terminal back pressure valves 5; Make to form certain back pressure in the pipeline, back pressure can be pushed into the cavity right-hand member with the piston in displacement transducer 2 31 piston cavity, and this displacement signal converts electrical signal into and exports controller 7 to.In the whole process of fuel feeding, displacement transducer 1 is accomplished fuel feeding and is detected, and when it has electrical signal output, shows that fuel feeding is normal; Displacement transducer 2 31 is accomplished pipeline leakage and is detected, and when it has electrical signal output, shows that pipeline does not have leakage; Otherwise oil feed line leaks.
Embodiment two:
To above-mentioned enforcement one, change displacement transducer 2 31 into pressure transducer 32 accordingly, concrete structure schematic diagram such as Fig. 2 ask; Detect the pressure state in the oil feed line 4 by pressure transducer 32, in the whole process of fuel feeding, displacement transducer 1 is accomplished fuel feeding and is detected; Pressure transducer 32 is accomplished pipeline leakage and is detected, and promptly when displacement transducer 1 has electrical signal output, shows that fuel feeding is normal; Otherwise fuel feeding is undesired to be that solenoid valve 1 stops up; Like back pressure valve 5 setting pressures is 3Mpa, when the detected pressures of pressure transducer is 3Mpa, explains that oil feed line 4 does not have leakage, when detected pressures breaks down greater than 3Mpa explanation back pressure valve 5, when detected pressures has been leaked less than 3Mpa explanation oil feed line 4.
