Abstract

PURPOSE:To make it possible to supply oil without stopping an engine to be tested, during an endurance test of the engine, by controlling the operation of an oil supply pump in accordance with the level of oil in an oil pan. CONSTITUTION:A supply pump 7 and an extraction pump 14 are disposed in an oil pipe 6 and oil pipe 11 which connect between a Y shape plug 2 attached to the bottom section of an oil pan 1 in an engine to be tested, and an oil tank 4. A control device 14 controls an electrical motor 8 serving as a drive source for both pumps which are therefore operated continuously or intermittently in the same time. When oil in the oil pan 1 reaches its set upper limit level during continuous operation, the operation of the engine is changed over into the intermittent operation to stop the rise of the oil level. With this arrangement, the automatic supply of oil may be carried out without the endurance test of the engine being interrupted, and the automatic adjustment of the oil level may be made.

(Problems to be Solved by the Invention) As described above, in the past, the engine was temporarily stopped during the engine durability test to replenish oil, which caused the following problems. In other words, if you suddenly stop a machine or engine that is rotating at high speed, it will have an adverse effect on the engine due to heat shrinkage, so it is necessary to gradually slow down and stop the engine. Sometimes, for the same reason, it is necessary to start the engine with gradual acceleration.As a result, the interruption time of the engine durability test is correspondingly longer. In addition, the tester had to check the amount of oil in the oil pan using an oil level gauge when refilling the oil, which lengthened the interruption time during the engine durability test and made the oil replenishment process more troublesome. ing.

In this automatic engine oil replenishment device configured as described above, when the test engine starts operating, in the case of intermittent operation control, the electric motor 8 is operated intermittently by the control device 14, and the supply pump 7 and the extraction pump 12 are operated intermittently. At the same time, perform intermittent operation. The intermittent operation of the supply pump 7 automatically replenishes the oil in the oil tank 4 to the oil pan 1 intermittently. In the case of continuous operation control, the electric motor 8 is operated continuously and the supply pump 7 and extraction pump 12 At the same time, the oil in the oil tank 4 is continuously and automatically replenished into the oil pan 1 by the continuous operation of the zero supply pump 7 which is operated continuously at the same time. In this case, both operation controls are applied to oil pan 1.
When excess oil exceeding the set upper limit oil level is replenished, the excess oil is sucked from the upper opening of the extraction pipe 3 and returned to the oil tank 4 by the extraction pump 12. In the case of intermittent operation control, When the operation setting timer of the electric motor 8 of the control device 14 is activated, the electric motor 8 is switched to the operating state, and the supply pump 7 and the withdrawal pump 12 are simultaneously switched to the operating state. Oil is continuously supplied to the oil pan 1, and the oil level within the oil pan 1 gradually rises.

When the operation setting time ends, the operation setting timer expires, the electric motor 8 is switched to the stopped state, and the supply pump 7 and the extraction pump 13 are switched to the stopped state again.
In addition, at the same time as the operation setting timer expires, the stop setting timer of the 1-torque motor 8 operates, and when the stop setting time ends, the stop setting timer expires, and at the same time the operation setting timer operates. The replenished amount is sucked in by the extraction pipe 5 as described above, and returned to the oil tank 4 by the extraction pump 12.

Here, if the oil supply pressure or oil supply flow rate in the oil pipe 6 becomes lower than the set value due to a malfunction of the supply pump 7, etc., the oil supply cutoff switch 10 detects this and turns on. Send a signal to 14. When the control device 14 receives an on signal (abnormality alarm signal) tl- from the oil supply cutoff switch 10, it stops the electric motor 8 and simultaneously switches the KR cutoff valves 9 and 13 to a fully closed state.

Therefore, backflow of oil within the oil pipes 6 and 11 can be prevented. In addition, when the electric motor 8 breaks down,
Since the supply pump 7 and the extraction pump 12 stop at the same time, excessive oil replenishment can be prevented. In this way, during an engine durability test, one oil pan 1
Even if the oil in the test engine drops to the set lower limit oil level, oil is refilled from the oil tank 4 to the oil pan 1 at set intervals and the oil level is controlled, so engine durability tests can be carried out without stopping the test engine. You can continue. In this embodiment, since the oil level gauge 5 with a scale is attached to the oil tank 4, the amount of oil consumed in the oil pan 1 can be easily read, and the work of measuring the amount of oil using an oil level gauge is eliminated. be able to. Note that the height position of the oil tank 4 with respect to the oil pan 1 is not particularly limited.
