Jacking oil pump filter element HBX-250×10

The function of the Jacking oil pump filter element HBX-250x10 at the outlet of the shaft oil pump is to reduce the vibration and noise of the entire oil pump electrical system, ensuring the excellent and reliable overall performance of the system. The shaft jacking device is an important component of the steam turbine unit, which plays a role in jacking the rotor during the start-up and shutdown processes of the unit, such as turning the engine to warm up and evenly cool down. The elliptical bearings of the steam turbine generator set are equipped with high-pressure jacking oil pockets. The high-pressure oil provided by the jacking device forms a static pressure oil film between the rotor and bearing oil pockets, forcibly lifting the rotor, avoiding dry friction between the shaft and the bearing during the low speed process of the steam turbine, reducing the turning torque, and playing an important role in protecting the unit, especially the rotor and bearings.
