11 are used to set system operational parameters, adjust system operating mode, control system working condition；Display 12 is arranged on fuel tank 1
On, for showing liquid level gauge 10, pressure sensor 8, the real time data of the feedback of temperature sensor 9 and instantaneous operating conditions and event
Hinder early warning etc..By the opening and closing of switching device 6 repeatedly, test system can complete to hold tested braking device of speed reducer
It is continuous, alternate to open and close, realize the simulation to braking device of speed reducer practical work process.
Exemplified by testing sealing property, concrete operation step is as follows：
Braking device of speed reducer 15 to be measured, is connected by the first step using fluid pressure line 14 with switching device 6.
Second step, startup test system, setting test parameter (including testing time, maximum working pressure (MWP) etc.) and Working mould
Formula (manually or automatically), proceeds by performing leak test.
In test process, when reversal valve is in right position, i.e., when switching device 6 is opened, work fluid passes through reversal valve stream
Enter in braking device of speed reducer 15, fluid flow direction is as shown in figure 3, braking device of speed reducer 15 is opened under oil liquid pressure effect；
When reversal valve is in left position, i.e., when switching device 6 is closed, work fluid flows back to fuel tank 1 by overflow valve 5, and fluid is flowed to such as
Shown in Fig. 4, braking device of speed reducer 15 is closed under own spring force effect, and the fluid of residual is also therewith by conveying oil return box 1.
Under the control of controller 11, whole test process reversal valve is constantly commutated, and pressure oil liquid is opened in braking device of speed reducer 15
Open-close-open in this circulation and constantly sealing engagement face is impacted.
3rd step, in test process and after test, the fluid that face is sealingly engaged on observation braking device of speed reducer oozes out
Situation, judges the sealing property of braking device of speed reducer.
When carrying out seal durability test, operating procedure is similar, need not simply limit total testing time, but need
The time of leakage takes place in record sealing engagement face, and the seal durability of braking device of speed reducer is considered with this.
