The main principle of the XQYD type new gas-wall sealing oil baffle is to allow dry compressed air to enter the air chamber of the oil baffle, and then exhaust through the air grooves on the air chamber. This causes the compressed air to form a ring-shaped air wall around the shaft diameter. The air wall completely wraps around the shaft diameter, preventing external steam from entering the bearing housing and also preventing the splashed lubricating oil in the bearing housing from approaching the copper teeth of the oil baffle. The new gas-wall sealing oil baffle completely solves problems such as water ingress into the lubricating oil and emulsification of the lubricating oil by steam. The new gas-wall sealing oil baffle adopts a non-contact air sealing method, eliminating the problem of carbon deposition at the tips of the oil baffle teeth. Problems such as shaft wear and unit vibration caused by carbon deposition on the oil baffle will no longer occur. The new gas-wall sealing oil baffle has six major advantages: 1. Safe and reliable; 2. Energy-saving and environmentally friendly; 3. Cost reduction; 4. Low failure rate; 5. Long service life; 6. High economic benefits.

The steam turbine generator rotor extraction device is a special equipment used when the generator rotor needs to be drawn out for maintenance during the generator overhaul process and when the generator rotor is to be reinserted after maintenance. This equipment solves the primitive method of manually pulling the generator rotor out and reinserting it with a chain block.When extracting or inserting the rotor, it is controlled by an electrical button, which can safely draw the generator rotor out and insert it into the designated position. The equipment is equipped with a clutch design. After the clutch is engaged or disengaged, the wire rope (with a traction force of 23 t) can be quickly reeled in or out by using the handwheel.The principle of the generator rotor extraction device is as follows: Connect the special flange for generator rotor extraction to the excitation end of the generator rotor, assemble the balance pulley set, connect it with the main engine using a steel wire rope, and then extract the rotor.The principle of the generator rotor insertion device is to insert the rotor into the stator of the generator by using the reaction force method. Fix the special fixed pulley set of the extraction and insertion device on the screw holes of the end face of the generator stator. Through the matching extension shaft and small cross beam, use the reaction force to push the rotor into the bore of the stator. The generator rotor extraction and insertion device is designed with two output speeds, and the two speeds can be used alternately during operation.

To meet the needs of civilized overhaul in power plants, we have designed fixed baffle supports and movable baffle supports for power plants. The two types of baffle supports are used to store the baffles of high and low pressure cylinders and small machine baffles. Using baffle supports to store baffles can bring convenience to maintenance personnel, save space at the maintenance site, and classify and store baffles neatly and beautifully.Product FeaturesFixed and movable baffle supports are made of rectangular seamless steel pipes, featuring good overall strength, large bearing capacity. The external dimensions and support point positions of the baffle supports are designed according to different baffle diameters and thicknesses to ensure that the baffles are safely and stably placed in the baffle racks without damage. The movable baffle support consists of an outer frame and an inner frame. Bearings are installed on the inner frame, enabling it to move back and forth on the track of the outer frame. Fixed and movable baffle supports enable maintenance personnel to carry out inspection, flaw detection, shot peening and other maintenance work on the baffles.
