Piston stroke of hydraulic actuator
Thread Content
Boss, is the stroke of the turbine’s oil actuator fixed by design and cannot be adjusted? How can these values be measured on-site?
It generally cannot be adjusted. The data can be measured using the scales on site
These are the design parameters; on-site adjustments are made based on these values. Sometimes the actual data deviates, and adjustments are necessary. There are adjustment screws on top of the oil valve
The maximum stroke of a hydraulic actuator is related to the size of the cylinder. To ensure reliability in operation, manufacturers generally do not allow the actuator to reach its maximum stroke; instead, they leave a certain margin of safety. If, due to scaling on the turbine, a valve opening of 100% is not sufficient to meet the load requirements, it is possible to increase the actuator’s stroke manually. In other words, by adjusting the stroke, the valve opening can be increased beyond 100%, thereby raising the steam inflow. The unit can be stopped and a valve adjustment test can be conducted to make these adjustments
