The filter screen of the small turbine oil pipeline is clogged, and the governor trips and stops. There are a few doubts: 1. The internal structure of the speed regulator is not clear. How to pump oil from the bearing box? 2. What is the principle behind the speed regulator tripping and stopping without lubricating oil supply? The speed regulator with this structure is very old. The new speed regulator has its own oil tank and does not need to pump oil from the bearing box of the small turbine. The speed regulator is inspected and calibrated by a professional organization. It has never been disassembled. It is relatively unfamiliar and there are no relevant drawings. Is there any master on the forum who has information that can be shared?
This type of equipment is directly dismantled, arranged in the order of disassembly, photographed, and the relevant gaps of the parts are measured and recorded while dismantling. Repair or replace problematic mechanical parts, and clean and rust-remove non-problematic parts. Then reinstall in order. When reassembly, follow the steps and reassemble according to the appropriate gap. The rotor must be rotated at each step. When rotating parts with bearing bushes, oil the bearing bushes to prevent dry wear. Then turn the whole thing manually (turn the car), confirm that there is no jamming phenomenon, and then you can start the test run. After all disassembly, the fuel tank, speed control box and transmission must be thoroughly cleaned. (Use dough stick for final cleaning) Be sure to keep it clean every step of the way when reassembly. After the test run is completed, it is recommended that the entire machine be painted with anti-corrosion paint, and it is better to apply silver paint to the heated parts. For reference. The oil pump of your equipment should be in the body itself, and the driving force may be obtained from the main rotor. This work can be done by ordinary maintenance workers, and no drawings or the like are needed.
There is a gear inside the speed regulator to form a chamber of a gear oil pump in the space to achieve the purpose of forced lubrication. It won't work without lubricating oil. Check to see if there is a sensor to send a signal to the actuator.
This may be a Woodward speed regulator, which is usually PG-PL and TG10. There is a gear oil pump inside for forced circulation filtration and cooling. There are: It is composed of a mechanical flyweight induction mechanism (there is also a hydraulic induction mechanism), a signal amplification servo mechanism, an oil motor actuator, a feedback stabilization mechanism, etc.
