In order to maintain the sealing of hydrogen inside the generator, the sealing oil system has become an indispensable component. In the sealing oil system, the role of the vacuum pump is crucial, and the reducer M01225.OBGCC1D1.5A that drives the vacuum pump to operate stably is the key equipment in this system. Now we will introduce in detail the working principle, technical characteristics of this reducer and its important role in the hydrogen-cooled generator sealing oil system.

I. The role and challenges of the hydrogen-cooled generator sealing oil system

The working principle of the hydrogen-cooled generator is to use the high thermal conductivity and low density of hydrogen to efficiently cool the inside of the generator, thereby improving power generation efficiency and reducing energy loss. However, the high permeability of hydrogen also brings sealing problems. In order to ensure the purity and pressure of hydrogen inside the generator, the sealing oil system is designed to prevent hydrogen leakage and external air from entering.

The core functions of the sealing oil system include:

1. Sealing effect: Form a barrier between the generator rotor and the sealing ring through the oil film to prevent hydrogen leakage.

2. Cooling effect: take away the heat generated by the friction between the sealing ring and the rotor.

3. Purification effect: extract the gas and impurities in the sealing oil through the vacuum pump to maintain the purity of the oil.

In this system, the role of the vacuum pump is particularly critical. It needs to run continuously to maintain the cleanliness of the oil and the stability of the system. However, the operation of the vacuum pump requires a stable low-speed and high-torque drive, while the motor usually provides a high-speed and low-torque output. At this time, the role of the reducer M01225.OBGCC1D1.5A is particularly important.

II. Working principle of reducer M01225.OBGCC1D1.5A

The reducer gearbox M01225.OBGCC1D1.5A is a high-precision transmission device specially designed for the vacuum pump in the hydrogen-cooled generator sealing oil system. Its core function is to convert the high-speed rotation of the motor into the low-speed and high-torque output required by the vacuum pump, thereby driving the vacuum pump to operate stably.

1. Transmission principle

The reducer achieves speed reduction and torque increase through the internal gear system. The high-speed rotation of the motor is transmitted to the reducer through the input shaft, and after the meshing transmission of multi-stage gears, the output shaft finally rotates at a lower speed while outputting greater torque. This transmission method not only meets the working requirements of the vacuum pump, but also ensures the stability and reliability of the system.

2. Lubrication and cooling

The reducer is equipped with an efficient lubrication system to ensure that the gears and bearings remain in good lubrication during operation. The lubricating oil not only reduces the friction and wear during gear meshing, but also plays a cooling role to prevent excessive temperature caused by long-term operation. In addition, the sealing design of the reducer can effectively prevent lubricating oil leakage and adapt to the high-demand environment of the sealing oil system of the hydrogen-cooled generator.

3. Precision design and materials

The gears and bearings of the reducer are made of high-strength alloy steel materials, and are precision machined and heat-treated to ensure their durability under high load and impact conditions. This design not only improves the service life of the reducer, but also reduces noise and vibration during operation, making it perform well in the complex working environment of the hydrogen-cooled generator.

III. Technical features of reducer M01225.OBGCC1D1.5A

The reason why reducer M01225.OBGCC1D1.5A can play an important role in the hydrogen-cooled generator sealing oil system is inseparable from its unique technical features:

1. High transmission efficiency

The reducer adopts optimized gear design and precision manufacturing process, and the transmission efficiency is as high as 95% or more. This not only reduces energy loss, but also reduces operating costs.

2. Low noise and low vibration

Through precise gear meshing and high-quality bearing support, the noise and vibration generated by the reducer during operation are extremely low, ensuring the smooth operation of the system.

3. High reliability and long life

The gears and bearings of the reducer have been specially treated to withstand high loads and frequent start-stop conditions, with a long service life and low maintenance costs.

4. Compact design and easy installation

The reducer has a compact structure and occupies little space, which is easy to install and arrange in the sealing oil system. At the same time, its modular design also makes maintenance and replacement more convenient.

IV. Application of reducer in hydrogen-cooled generator sealing oil system

In the hydrogen-cooled generator sealing oil system, reducer M01225.OBGCC1D1.5A works closely with the motor and vacuum pump to complete the following tasks:

1. Driving the vacuum pump

The reducer converts the high-speed rotation of the motor into the low-speed and high-torque output required by the vacuum pump, ensuring that the vacuum pump can operate stably and efficiently. The vacuum pump maintains the purity of the oil by extracting the gas and impurities in the sealing oil, thereby maintaining the sealing of the hydrogen inside the generator.

2. Maintaining system stability

The high-precision transmission and low-vibration characteristics of the reducer ensure the smooth operation of the vacuum pump and avoid system instability caused by vibration or speed fluctuations. This is essential for the long-term operation of hydrogen-cooled generators.

3. Reduce maintenance costs

The high reliability and long-life design of the reducer reduce the maintenance frequency and failure risk of the system and reduce the operating cost. At the same time, its modular design also makes maintenance and replacement more convenient.
