Detailed description of the invention
Being described principle of the present utility model and feature below in conjunction with accompanying drawing, example is served only for explaining this practicality
Novel, it is not intended to limit scope of the present utility model.
As it is shown in figure 1, rubber-roller machine control pressurer system, including fuel tank 1, the oil outlet end of described fuel tank 1 passes through the first oil circuit
11 are connected with hydraulic oil pump 2, check valve 3, overflow valve 4 and rubber roll oil piping system in turn, and described overflow valve 4 is by the second oil circuit 12
Connecting described fuel tank 1, the first oil circuit 11 between overflow valve 4 and rubber roll oil piping system is provided with oil gauge 5；Described rubber roll oil circuit system
System is composed in parallel by upper roller oil piping system A and lower roll oil piping system B, described upper roller oil piping system A and the oil of lower roll oil piping system B
Road is identical；Being provided with three-position four-way valve 6 in described rubber roll oil piping system, the oil inlet end of described three-position four-way valve 6 passes through the 3rd oil circuit
13 are connected with hydraulic control one-way valve 10, accumulator 7 and rubber roll oil cylinder 9 in turn, are provided with oil pressure between described accumulator 7 and rubber roll oil cylinder 9
Table 8；Described rubber roll oil cylinder 9 rod chamber is sequentially connected with described three-position four-way valve the 6, the 5th oil pipe 15 and described by the 4th oil pipe 14
The oil inlet end of fuel tank 1；Described rubber roll oil cylinder comprises the oil cylinder that at least two groups are in parallel.
Work process: when rubber-roller machine runs, three-position four-way valve 6 is in the first valve position, and fuel tank 1 provides for hydraulic oil pump 2
Hydraulic oil, hydraulic oil flow to overflow valve 4 through check valve 3, and overflow valve 4 plays level pressure overflow effect, hydraulic pressure in control pressurer system
