Abstract
The present disclosure relates to a monitoring system for a hydraulic system in a comminution apparatus including at least one pressurized accumulator. The monitoring system includes at least one pressure sensor and a control unit, wherein the pressure sensor is connected to the control unit. The pressure sensor is arranged to measure a pressure in the at least one accumulator and the control unit is configured to determine that a pressure in the accumulator is outside of a predefined range. The control unit is further configured to control a pressure regulating system that is arranged to restore the pressure in the pressurized accumulator.
Claims13
A monitoring system for a hydraulic system in a comminution apparatus including at least one pressurized accumulator, wherein the pressurized accumulator comprises a first chamber containing hydraulic liquid and a second chamber containing a pressurized gas, wherein said monitoring system comprises at least one pressure sensor and a control unit, wherein said pressure sensor is connected to said control unit, said pressure sensor being arranged to measure a pressure in said at least one accumulator and wherein the control unit is configured to determine that a pressure in said accumulator is outside of a predefined range and wherein the control unit is further configured to control a pressure regulating system arranged to restore the pressure in the pressurized accumulator, wherein the pressure sensor is arranged to measure a gas pressure in said second chamber, wherein the second chamber of each accumulator is connected to a source of pressurized gas via a manifold block, and wherein the manifold block comprises solenoid valves.
A comminution apparatus including at least one pressurized accumulator comprising a first chamber containing hydraulic liquid and a second chamber containing a pressurized gas, said comminution apparatus comprising a monitoring system, wherein said monitoring system comprises at least one pressure sensor and a control unit, wherein said pressure sensor is connected to said control unit, said pressure sensor being arranged to measure a pressure in said at least one accumulator and wherein the control unit is configured to determine that a pressure in said accumulator is outside of a predefined range and wherein the control unit is further configured to control a pressure regulating system arranged to restore the pressure in the pressurized accumulator, wherein the pressure sensor is arranged to measure a gas pressure in said second chamber, wherein the second chamber of each accumulator is connected to a source of pressurized gas via a manifold block, and wherein the manifold block comprises solenoid valves.
