The brake oil pressure of steam turbine refers to the oil pressure used to control the brake operation during the operation of steam turbine. The brake is used to quickly stop the operation of the turbine in an emergency by spraying high-pressure oil on the turbine to brake and shut down the turbine. The stability and accuracy of gate oil pressure are very important to ensure the safe operation of steam turbine. Proper brake oil pressure can ensure that the turbine can be stopped quickly and safely in an emergency to avoid accidents. Therefore, the monitoring and maintenance of gate oil pressure is an important part of turbine operation management.
The hanging gate is to move the slide valve from the lower fulcrum position to the upper fulcrum position through the action of oil pressure before the turbine starts up, so as to establish the oil pressure to realize the subsequent turbine impulse and other work.
