When pushing oil level indicator 14, the sealing formed between oil level indicator 14 and sealing frock 3 can prevent liquid from flowing into sealing
In the inner cavity of tooling 3.By the way of pull rod 7 and the first compressed spring, the initial drawing that sliding panel 2 is subject to can be conveniently adjusted
Power, and the first compressed spring is always positioned on liquid level, is conducive to the durability and stabilization that keep oil level indicator experimental rig
Property.
In another embodiment, elastomeric element 8 is the second compressed spring (not shown), and the upper end of the second compressed spring is supported
It is connected to the lower surface of sliding panel 2, the lower end of the second compressed spring is connected to pedestal 1 or sink 13, and the second compressed spring can be arranged
On guide post 5, when original state (when driving mechanism 10 does not apply thrust), sliding panel 2 is located on liquid level, pushes away in driving mechanism 10
Dynamic sliding panel 2 enters before liquid, and the second compressed spring need to ensure oil level indicator 14 and sealing frock to the thrust of sliding panel 2
The sealing formed between 3 can prevent liquid from flowing into the inner cavity of sealing frock 3.It should be noted that elastomeric element 8 can also be with
Using the elastic component of other forms, it is not limited to spring.
The test method of oil level indicator experimental rig mainly comprises the steps that
1, oil level indicator experimental rig is in its natural state as shown in Fig. 2, elastomeric element 8 passes through the pressure of adjusting nut 9
Elastic force is passed to sliding panel 2 by pull rod 7, it is ensured that sliding panel 2 is in the above position of liquid level (shown position) by contracting；
2, oil level indicator 14 is placed on sealing frock 3；
3, the downing switch of driving mechanism 10 is opened, driving mechanism 10 drives 4 downlink of pushing mechanism and oil level indicator 14
Upper surface contact, passes to oil level indicator 14 for downward pressure.The upward elastic force that sliding panel 2 provides elastomeric element 8
Sealing frock 3 and oil level indicator 14 are passed to, so that forming certain sealing effect between sealing frock 3 and oil level indicator 14
Fruit, when which ensures that oil level indicator 14 is into liquid, liquid does not enter in the inner cavity of sealing frock 3；
4, since the downlink strength of cylinder is far longer than the elastic force of elastomeric element 8, driving mechanism 10 continue traveling downwardly until
Sliding panel 2 is contacted with pedestal 1, and oil level indicator 14 is completely immersed in liquid.The operating pressure of driving mechanism 10 acts on oil level
On sealing ring 15 between indicator 14 and sealing frock 3, which ensures the compression of filling 0.4MPa in sealing frock 3
Air is without leaking；
5, the air circuit breaker of test compressed gas is opened, test compressed air is filled in the inner cavity of sealing frock 3, observes
Whether oil level indicator 14 bubbles determine whether product sealing effect is good；
6, after the completion of leakage test, test compressed air is closed, and the compressed air of the inner cavity of sealing frock 3 is discharged；
7, the upstream switch of driving mechanism 10 is opened, pushing mechanism 4 moves upwards, and sliding panel 2 is also in the work of elastomeric element 8
It firmly moves upwards down, eventually stops at the position of liquid level or more；
8, oil level indicator 14 is removed from sealing frock 3, completes test.
The oil level indicator experimental rig of the utility model avoids test tool and is threadedly coupled with oil level indicator, thus
It prevents and is threadedly coupled possible damage and pollution.In addition the external screw thread of existing test tool and oil level indicator connects
It connects, the compressed gas of test is located at the inside of oil level indicator, and (inside is when oil level indicator uses towards in gear-box
Side), i.e. the pressure direction of compressed gas be it is outside from the inside of oil level indicator, the sheet glass in oil level indicator is pressed
The sealing ring on the outside of sheet glass can be compressed after power, cause the sealed pressure of sheet glass to increase, it is therefore possible to lead to not
Obtain correct testing result.And the compressed gas of the oil level indicator experimental rig test of the utility model refers to positioned at oil level
Show the outside of device, then can avoid above situation, be conducive to the accuracy of test data.
