Description

  The present invention relates to an oil cooler leakage check device, and in particular, an oil cooler leak suitable for confirming the presence or absence of oil leakage by observing the cooling water of an oil cooler installed in a power plant or the like. It relates to a confirmation device.

  In an oil cooler such as a lubricating oil cooler installed in a power plant or ship engine room, if the cooling pipe is broken or cracked, the oil enters the cooling water and interferes with the operation of the generator or ship engine. Therefore, the presence or absence of oil leakage in the oil cooler is confirmed by various methods.

  For example, in the oil leakage detection system disclosed in Patent Document 1 below, a cooling water outlet header pipe provided behind a cooling water outlet valve, an oil detector attached to the cooling water outlet header pipe, and a console Provided with an oil content detection indicator lamp, a signal line for connecting the oil content detector and the oil content detection indicator light, a signal line connection box for connecting the signal line, and a power source for operating each device, and a cooling water outlet The oil in the cooling water flowing into the header pipe is detected by the oil detector, the detection signal is output to the oil detection indicator via the signal line connection box and signal line, and the oil detection indicator is turned on. An abnormality of the cooling pipe of the cooler is detected and recognized by the driver.

  However, since the oil leakage detection system disclosed in Patent Document 1 described above is a technique for lighting the oil content detection indicator lamp and causing the driver to recognize an abnormality in the cooling pipe of the oil cooler, the cooling water outlet header pipe and It is necessary to provide an oil detector, an oil detection indicator, a signal line, a signal line connection box, and a power source. Therefore, there is a problem that the configuration is complicated and the equipment cost is high.

  An object of the present invention is to provide an oil cooler leakage check device that can be simplified in configuration.

Embodiments of an oil cooler leakage check apparatus according to the present invention will be described below with reference to the drawings.
The mounting position and configuration of an oil cooler leakage check device 10 (hereinafter referred to as “oil leakage check device 10”) according to an embodiment of the present invention will be described with reference to FIGS. 1 (a) and 1 (b). To do.
In the oil cooler 1 shown in FIG. 1A, oil (for example, lubricating oil for a generator, a ship engine, etc.) flows through the oil inflow pipe 2 and passes through the oil inflow valve 3. After being cooled by the cooling water flowing in the cooling water inflow pipe 6 and flowing into the oil cooler 1 through the cooling water inlet valve 7, the oil extraction pipe 4 is passed through the oil outflow valve 5. It flows out and is returned to a generator or a ship engine. The cooling water that has flowed into the oil cooler 1 flows through the cooling water outlet pipe 8 through the cooling water outlet pipe 9 and flows out to the outside.

  As shown in FIG. 1A, the oil leakage confirmation device 10 is located behind the cooling water outlet valve 9 of the cooling water outflow pipe 8 attached to the oil cooler 1 (on the side opposite to the oil cooler 1). It is attached.

  Further, as shown in FIG. 1 (b), the oil leakage confirmation device 10 is attached to the cooling water outflow pipe 8 at its end so as to extend vertically upward with respect to the pipe axis direction (longitudinal direction) of the cooling water outflow pipe 8. The oil leakage confirmation cooling water intake pipe 11, the oil leakage confirmation cooling water intake pipe 11, and the lateral direction (relative to the pipe axis direction of the oil leakage confirmation cooling water intake pipe 11 The observation window 13 attached to the tip of the oil leakage confirmation cooling water intake pipe 11 so that the inside of the oil leakage confirmation cooling water intake pipe 11 can be seen from the vertical direction), and the tube axis of the cooling water outflow pipe 8 An oil leakage confirmation cooling water discharge pipe 14 attached between the intake valve 12 and the observation window 13 of the oil leakage confirmation cooling water intake pipe 11 so as to extend parallel to the direction, and the oil leakage confirmation cooling And a discharge valve 15 attached to the water discharge pipe 14.

Next, an oil leakage confirmation method of the oil cooler 1 using the oil leakage confirmation device 10 will be described with reference to FIGS. 2 (a) and 2 (b).
When the monitoring person checks the cooler 1 regularly (for example, once / day), after confirming that the discharge valve 15 is closed, the intake valve 12 is opened and the cooling water outflow pipe is opened. The cooling water flowing through 6 is taken into the cooling water intake pipe 11 for oil leakage confirmation.

  Thereafter, the monitoring person keeps the intake valve 12 open and looks at the inside of the cooling water intake pipe 11 for checking oil leakage from the observation window 13.

  At this time, if there is no oil leakage in the oil cooler 1, the oil leaks from the observation window 13 after a certain time (for example, 1-2 minutes) after the cooling water is taken into the cooling water intake pipe 11 for oil leakage confirmation. When the inside of the cooling water intake pipe 11 for oil confirmation is viewed, only the cooling water 21 is visible as shown in FIG.

On the other hand, when there is oil leakage in the oil cooler 1, the oil leakage confirmation cooling water intake pipe 11 is inserted into the oil leakage confirmation cooling water intake pipe 11 from the observation window 13 after a certain period of time after the cooling water is taken into the oil leakage confirmation cooling water intake pipe 11. 2, the cooling water 21 and the oil 22 accumulated on the cooling water 21 can be seen as shown in FIG.
Thereby, the monitoring person can confirm the presence or absence of oil leakage in the oil cooler 1 only by looking inside the cooling water intake pipe 11 for oil leakage confirmation from the observation window 13.

  In addition, the monitoring staff collects oil 22 on the cooling water 21 in the cooling water intake pipe 11 for oil leakage confirmation even if a certain time has elapsed after the cooling water is taken into the cooling water intake pipe 11 for oil leakage confirmation. If it is confirmed that the intake valve 12 is closed, the discharge valve 15 is opened and the cooling water 21 in the oil leakage confirmation cooling water intake pipe 11 is discharged through the oil leakage confirmation cooling water discharge pipe 14. . Thereafter, the monitor closes the discharge valve 15 and finishes the oil leakage check operation.

On the other hand, when the monitoring person confirms that there is oil leakage in the oil cooler 1, after closing the intake valve 12, the monitoring valve opens the discharge valve 15 and leaks oil through the cooling water discharge pipe 14 for oil leakage confirmation. The cooling water 21 in the cooling water intake pipe 11 for confirmation is discharged. Thereafter, the monitoring person closes the discharge valve 15, then opens the intake valve 12, takes again the cooling water flowing in the cooling water outflow pipe 6 into the cooling water intake pipe 11 for oil leakage confirmation, and passes the elapsed time. At the same time, the amount (thickness) of the oil 22 accumulated on the cooling water 21 is observed.
Thereby, the supervisor can grasp | ascertain the leak condition (degree of leak) of the oil in the oil cooler 1. FIG.

  As described above, by using the oil leakage confirmation device 10 according to the present embodiment, it is possible to confirm the presence or absence of oil leakage in the oil cooler 1 with a simple configuration.
