The compensation valve 4 can be a manual valve or an electromagnetic valve, that is, the compensation valve 4 can be manually controlled or electrically controlled, and similarly, the compensation pump 5 is a conventional liquid pump for controlling the liquid flow rate and can be manually controlled or electrically controlled. In this embodiment, in order to realize automatic compensation, the oil level compensation device further includes a controller 13, a first oil sensor 11, and a second oil sensor 12. The controller 13 may be a conventional control device, such as a single chip or a DSP.
As shown in fig. 1, the first oil amount sensor 11 is provided at the lowest allowable oil level position in the oil storage tank 1, and the second oil amount sensor 12 is provided at the highest allowable oil level position in the oil storage tank 1. When the actual oil level of the oil tank 1 falls to the minimum allowable oil level, the first oil amount sensor 11 outputs a signal; when the actual oil level of the oil tank 1 increases to the maximum allowable oil level, the second oil amount sensor 12 outputs a signal. Both the first oil amount sensor 11 and the second oil amount sensor 12 may be conventional liquid level detection devices. The minimum allowable oil level position and the maximum allowable oil level position are set according to actual needs.
