Liquidometer 10 is installed to any one on requiring liquid level check valve 20 below, in the present embodiment 3, if it is desired to oil level
The position shown in dotted line, then liquidometer 10 may be alternatively mounted at any one place in liquid level a, b, c below.
When installing liquidometer 10, liquid level display part 19 need to be kept vertical, and opening upwards, by oil pipe 12 and check valve 20
After connection, oil pipe 12 opens spool 26, and a small amount of lubricating oil in hub reduction gear 30 flows into oil pipe 12, oil by check valve 20
Oil in pipe 12 enters liquid level display part 19 by connection component, damping piece 17.
Different size of damping hole 175 is selected according to the oil of different viscositys, to flow into lubricating oil with suitable flow velocity
Liquid level display part 19 prevents from spraying because flow velocity is too fast.
The intracorporal a small amount of hydraulic lubricant oil of case is entered in liquid level display part 19 by damping hole 175, forms the pressure such as one
Chamber, according to Pascal's theorem, the liquid level in liquid level display part 19 will be flushed with 30 internal liquid level of hub reduction gear, by observing liquid
The liquid level of position display part 19 can visually detect the oil mass in hub reduction gear 30.
The liquidometer 10,26 self-return of spool in check valve 20 are removed after having detected, check valve 20 is closed.Liquidometer
A small amount of residual oil liquid in 10 can be recycled or be discarded.
It should be noted that in the absence of conflict, the feature in embodiment in the present invention can be combined with each other.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
