Description
Technical field
The utility model relates to lubrication system, specifically is a kind of lubrication system with pipeline leak detection function.
Background technique
In various lubrication systems, the oil plant leakage problem of pipeline exists always, and this also will directly influence the lubrication effect of fueling injection equipment, damages if find the untimely relevant device that also can cause, thereby causes heavy losses.Lubrication system commonly used is monitored the output of lubricant oil through the unlatching of monitoring respective valves, and when monitoring valve opening, normal supply is thought by system; Thinking during valve closing does not have fuel feeding.But for industry spot, leak, for equipment, still can not reliably obtain fuel feeding, still have the risk of damaging in case the pipeline behind the valve exists.Therefore, the pipeline leak detection function of lubrication system is particularly important.
The model utility content
To above defective, the utility model provides a kind of lubrication system with pipeline leak detection function, can realize real-time monitored pipeline state, guarantees the reliability of equipment fuel feeding.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme:
A kind of lubrication system with pipeline leak detection function; Comprise with the control valve that comes oil pipe line to be connected, be used to detect the sensor one and the oil feed line of said control valve opening state; Back pressure valve is installed being positioned at the fuel feeding point place that oil feed line do not hold, this back pressure valve can be opened under setting pressure; The sensor two that is used for the detected pressures state is installed on the said oil feed line.
Preferably, said control valve adopts solenoid valve, pneumatic valve or hydraulic operated valve.
Preferably, said sensor one is a displacement transducer.
Preferably, said sensor two is a pressure transducer.
Further, said lubrication system also comprises the control gear that is electrically connected with said sensor one, sensor two and control valve.
Special, said back pressure valve and fuel feeding point removably link together or become one.
The described lubrication system of the utility model with pipeline leak detection function, through back pressure valve is installed before fuel feeding point, when control valve was opened, back pressure valve was opened under setting pressure to fuel feeding point normal fuel injection; Whether when control valve was closed, back pressure valve cut out and makes oil feed line keep corresponding pressure, keep through detecting corresponding pressure, can confirm whether pipeline exists leakage, thereby reach leak detection function; The further control gear through being connected with control valve with sensor can be realized the control of this lubrication system and function of measuring accordingly.

According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the said embodiment's one of the utility model a structural principle schematic representation;
Fig. 2 is the said embodiment's two of the utility model a structural principle schematic representation;
Fig. 3 is the structure principle chart of the said back pressure valve of embodiment.
Among the figure:
1, solenoid valve; 2, displacement transducer one; 31, displacement transducer two; 32, pressure transducer; 4, oil feed line; 5, back pressure valve; 6, fuel feeding point; 7, control gear; 8, in-line; 51, valve body; 52, spool; 53, spring.
Embodiment
Embodiment one:
As shown in Figure 1, provided a specific embodiment structure principle chart of the said lubrication system of the utility model.Its formation comprise with the solenoid valve that comes oil pipe line 8 to be connected 1, solenoid valve 1 on displacement transducer 1 is installed; This sensor is used to detect the opening state of solenoid valve 1; The outlet of solenoid valve 1 connects oil feed line 4; Put 6 places at its fuel feeding of not holding back pressure valve 5 is installed, back pressure valve 5 removably links together with fuel feeding point 6 or becomes one; This back pressure valve 5 can be opened under setting pressure; The displacement transducer 2 31 that is used for the detected pressures state is installed on the said oil feed line 4.Displacement transducer 1, displacement transducer 2 31 and solenoid valve 1 are electrically connected with control gear 7, and this control gear 7 can receive the information of two sensors and be used for the keying of control electromagnetic valve 1.
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 control gear 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.
Fig. 3 has provided the structure principle chart of the back pressure valve that the utility model adopted 5; It is made up of valve body 51, spool 52, spring 53; When its import has certain pressure; Can promote the elastic force that spool 52 overcomes spring 53, thereby make back pressure valve open conducting, corresponding magnitude of back pressure can realize through the elastic force that changes spring 53.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But the utility model is not limited to the detail in the above-mentioned mode of execution, in the technical conceive scope of the utility model; Can carry out multiple simple variant to the technological scheme of the utility model; Also can adopt pneumatic valve or hydraulic operated valve to replace like control valve, the form of change control terminal and mounting point etc., these simple variant all belong to the protection domain of the utility model.
