Description

System for quantitative monitoring of fueling

More particularly, the present invention relates to a lubrication controller for lubrication of a lubrication apparatus by detecting whether or not the lubrication oil is contained in the vapor recovered from the lubrication port of an automobile, And an oil leakage detection unit for generating an emergency control signal to provide a metered fuel supply monitoring function.

The 'vapor' is generated when the fuel oil is injected into a fine gap, or when the fuel oil contacts with the high-temperature equipment and is vaporized. When the vapor concentration of the vapor increases or the high temperature is applied in the closed space There is a risk of explosion.

Techniques have been proposed for eliminating oil vapor, such as installing vapor monitoring equipment, temperature monitoring equipment, or installing equipment for recovering vapor. As such prior arts, Korean Patent Laid-Open No. 10-2004-0020313 entitled " Vapor Inhalation Apparatus for Lubricating Oil Purifier " and Korean Patent No. 10-0786623 entitled " Liquid Porous Lubricator Having Vapor Recovery Function "

However, since the conventional arts do not monitor the leakage amount, the oiling worker and the driver can not recognize the leakage amount even if the oil is not supplied.

As a technique for solving such a problem, the present applicant has proposed Korean Patent No. 10-1787688 entitled " Vapor Collector Monitoring System ". In the conventional art, it is detected that leakage fluid is contained in the recovered oil vapor, so that leakage is detected during oiling, and the control unit controls the oiling situation.

However, in the above-described prior art vapor recovery and monitoring system, in the detailed implementation process of the present applicant, which is not based on disclosure, a detailed configuration of a lubricator is provided so as to additionally provide a leak detection unit in a lubricator controller for controlling a common oil supply pump Further improvements to this detailed configuration have been desired.

For example, in the detailed construction of the related art, when the lubricant controller detects the leakage of fuel during oiling in the state where the lubricant controller is controlled to be turned ON according to a normal lube oil input, And the additional direct oil supply pump is controlled to be OFF (emergency state operation).

However, at this time, the lubricator controller, which controls the basic operation of the lubricator, does not directly control the oil feed pump (emergency operation) but controls the oil feed pump directly so that the lubricator controller does not control the entire control of the lubricator There was a limit that could not be done. For example, although the lubricator controller has continuously recognized the oil feed pump by the ON control, the oil feed pump may be turned off by the oil leak detection unit.

In addition, in the configuration in which the leakage detection unit directly controls the emergency state operation, although the normal oil supply structure is achieved so that the usual input and output means (user interface) of the lubricator is controlled by the lubricator controller, It has been necessary to provide or control the alarm display means.

1 is a schematic diagram of a metered quantity lubrication monitoring apparatus installed in a gasifier according to an embodiment of the present invention.

The quantitative lubrication monitoring apparatus according to an embodiment of the present invention is installed in a gasifier (F).

The gasifier device F includes a gas supply nozzle 200 and a gasifier 100. In FIG. 1, the ladle 100 is shown as a stand type, but the present invention is not limited thereto. A ceiling ladle may also be regarded as a ladle 100 of the present invention.

The fueling nozzle 200 includes a supply unit 220 for supplying fuel oil to the fuel filler port A of the vehicle and a recovery unit 240 for recovering the fuel vapor from the fuel filler port A of the vehicle.

For example, the inside of the injection nozzle 200 may be formed as a double pipe structure including a center tube and an outer tube surrounding the center tube. The supply part 220 for supplying the fuel oil can be understood as a center pipe, and the recovery part 240 for recovering the fuel oil can be understood as an outer pipe.

The oil supply pipe 122 is divided into upper and lower parts in order to facilitate understanding of the oil supply pipe 122 and the return pipe 124. However, when the oil supply nozzle 200 is configured as a double pipe, And the return pipe 124 may be connected to the outer pipe and may be provided on the outer side in the form of surrounding the center pipe. The mechanical configuration of the gasifier 100 or the gas nozzle 200, which is not described in detail in this embodiment, can be referred to in Korean Patent Nos. 10-1114971, 10-0262869, 10-1439172, etc. have.

The oil pump 100 is connected to the oil supply nozzle 200 through the oil supply pipe 122 and is connected to the oil supply nozzle 200 through the oil supply pump 140, And collects the vapor from the fuel injection nozzle 200 by the operation of the recovery pump 160.

The recovery pump 160 is a pump having a function of a gas suction device (for example, an air pump) for sucking and transporting vapor, and is configured to be capable of sucking the vapor from the outer end of the gas supply nozzle 200.

The operation of the recovery pump 160 when unexpected leakage occurs at the outer end of the injection nozzle 200, the interior of the injection nozzle 200, the connection between the injection nozzle 200 and the oil feed pipe 122, The leakage fluid can be sucked into the recovery pipe 124 together with the vapor.

That is, it can be understood that the leakage fluid contained in the recovered water recovered by the recovery pump 160 has a problem when oiling the oil, and the occurrence of the leakage fluid means that the oil is not discharged in a fixed amount.

Therefore, when leakage fluid is generated, it is desirable to take an emergency state operation such as stopping the oil supply and / or outputting an alarm.

In addition, the emergency state control function can be variously configured without changing the configuration of the lubricator controller 410 itself, which is provided to control the basic lubrication function in the lubricator device F. In addition, There is an advantage to be able to do. These advantages are particularly useful when the oil recovery and leak detection functions are extended and installed in a conventional oil lubrication apparatus that does not have a vapor recovery function.

In this case, And outputs a control signal. For example, the recovery unit controller 420 is connected to the signal input side of the recovery unit controller 420 to the control signal line output from the lubricator controller 410 to the refueling pump 140 to sense a control signal have.

When the emergency state signal is transmitted from the leakage detection unit 430 while the ON control signal is being output, the lubricator controller 410 outputs an OFF control signal to the oil supply pump 140, .

The recovery unit controller 420 outputs an OFF control signal to the recovery pump 160 when an OFF control signal is output from the lubricator controller 410 to the refueling pump 140 Output.

In the present embodiment, when the emergency state signal is generated from the leakage detection unit 430, both the oil supply pump 140 and the recovery pump 160 are controlled to be OFF to perform both the fuel oil operation and the vapor recovery operation Emergency state control in a stopping manner. This is an advantageous way to reliably implement the stop control according to the emergency condition and to deal with the leakage problem.

The lube oil controller 410 outputs an ON control signal to the oil supply pump 140 when the lube oil operation start command is input through the input unit 442. The lube oil pump controller 410 outputs the on- And outputs an OFF control signal to the oil supply pump 140 when it is determined that the flow measurement value provided from the oil supply pump 140 reaches the input flow rate input through the input means 442.

When the amount of leakage as a reference of the emergency state signal is set low or when the oil supply flow rate at the oil supply reaches almost the completion of oil supply at the input flow rate (for example, 90% oil supply progress) It may be ineffective to stop all the operations until the lubrication operation and to confirm the operator. In this case, the leak recovery operation can be stopped and the lubrication operation can be completed to prevent the leakage fluid from being continuously generated.

FIG. 5 is a partial cross-sectional view of a leakage fluid sensor according to an embodiment of the present invention. FIG. FIG. 6 is an operational state diagram of the leakage fluid detection sensor unit according to an embodiment of the present invention.

For example, as shown in FIG. 5, the leakage detecting sensor unit 300 includes a housing 320, an inflow tube 340 formed at one side of the housing 320 and through which the collected material flows, And a discharge pipe portion 350 formed on the other side of the housing 320 and discharging the vapor separated from the recovered product.

The leakage detecting sensor unit 300 separates the recovered water flowing into the housing 320 through the return pipe 124 into a vapor stream and a leakage fluid.

For example, when the recovered material flows into the inflow pipe portion 340 through the return pipe 124, the recovered oil is discharged to the discharge pipe portion 350 by the recovery pump 160, It can not move to the inner side of the housing 320 due to its own weight.

At this time, the separated vapor is sent to the fuel oil supply side, and the leakage fluid is stored in the housing 320.

The fuel oil supply side may be, for example, a reservoir 500, a gasoline nozzle 200, an oil feed pipe 122, or the like, through a liquefier (not shown) for liquefying the oil vapor and reusing the fuel oil It is preferable to send it to the fuel oil supply side.

The leakage detecting sensor unit 300 senses leakage of leakage fluid of a reference capacity or more to the housing 320 and senses leakage.

As used herein, the term " reference capacity " is a sensing reference value for confirming whether a fixed amount of lubrication is performed. For example, the reference capacity may be a predetermined amount irrespective of the amount of lubrication.

The leakage detection sensor unit 300 includes a leakage fluid detection sensor 360 for detecting whether the amount of leakage fluid stored in the housing 320 reaches a reference capacity.

For example, the leak detecting sensor 360 may be implemented by a type of position sensor or a level sensor including a magnetic switch (e.g., a lead switch) A variety of known sensors may be used.

In the present embodiment, the leakage leakage detecting sensor 360 will be described based on the position sensor using the reed switch.

For example, the leaked-fluid detecting sensor 360 includes a two-wire signal transmitting portion 362 having switch contacts 362a and 362b at one end thereof, and a signal transmitting portion 362 having the switch contacts 362a and 362b. A magnetic tube 364 having the switch contacts 362a and 362b therein so as not to affect the state of the switch contacts 362a and 362b and a magnetic body A body 367 formed on the outside of the vacuum tube 364 and surrounding the signal transmission part 362 up and down and a floating body 367 which is movable up and down the body 367, And a float 368 configured to float at least a portion of the leakage fluid upward.

As shown in FIG. 6, the leakage amount detection sensor 360 gradually increases the height of the leakage fluid D while the leakage fluid D is stored in the housing 320, and the height of the leakage fluid D The float 368 rises together.

The leakage detecting sensor unit 300 may further include a snap ring 369 at a predetermined distance above and / or below the float 368. The snap ring 369 may include a float 368 And acts as a stopper for controlling excessive rise or fall of the battery.

6, when the float 368 rises and a predetermined portion of the float 368 (for example, the upper and lower middle portions of the float 368) is positioned at a position corresponding to a preset leak fluid height h, The switch contacts 362a and 362b are charged to different polarities by the induction magnetic force of the magnetic body 366 and the switch contacts 362a and 362b are attracted to each other by mutual contact Signal.

At this time, the leakage detection unit 430 receives a signal sensed by the leakage sensing unit 300, and generates an emergency state signal when it is judged to be leaked based on the received signal.

For example, if the leakage fluid is stored by the preset leakage fluid height h, it is determined that the leak fluid is not leaked. If the leakage fluid is not stored by the preset leakage fluid height h, have.

For example, the leakage detection unit 430 can be set to be leaked when the amount of leakage fluid reaches a leakage fluid height corresponding to a specific value (for example, 150 ml or 200 ml) irrespective of the actual injection amount , Where this specific value (e.g., 150 ml or 200 ml) is set as the reference volume.

The leakage fluid detection sensor 360 detects a leakage signal from the leakage detection sensor 430 when the stored leakage fluid D reaches the reference capacity, Lt; / RTI >

The leakage detection unit 430 is configured to generate an emergency state signal when it determines that the amount of leakage fluid corresponding to the sensing signal is a preset reference capacity.

The leakage detection unit 430 may be configured to generate an emergency state signal when the amount of the leakage fluid corresponding to the sensing signal exceeds a preset reference capacity.

The reference capacity relative to the main amount of fuel is set in proportion to the amount of fuel to be supplied. For example, the upper limit of an allowable tolerance range defined as a fixed amount based on a specific amount of fuel (for example, 20 L) , 150 ml).

The reference capacity to the main flow rate may be set to a fixed amount (e.g., 150 ml) or a constant rate (e.g., 0.5%).

For example, the pre-set lubricant fluid height h may be set based on the amount of fuel oil corresponding to the upper limit of the allowable tolerance range for the amount of fuel injected when a constant amount of fuel is injected. For example, The height of the leakage fluid corresponding to 150 ml may be set to be the leakage fluid height judged to be leaking.

The subsequent process configuration according to the generation of the emergency state signal is as described above. The contents of the leaky fluid detection sensor unit 300 may be referenced in the Korean Registered Patent No. 10-1787688 filed by the present applicant.
