Research on diagnostic methods The expert system based on artificial intelligence and artificial neural network are currently two methods for fault diagnosis of plum blossom coupling units in China, and there are many differences between the two. Abnormal vibration of steam turbine During the operation of the steam turbine, when there are phenomena such as friction vibration, rotor thermal deformation, air flow excitation, etc.

The inspection of the internal conditions of the condenser revealed that there is a relationship between the decrease in vacuum and the leakage of the low-pressure cylinder joint surface. For example, in March 2011, the condenser of Unit 2 of Nanhai Power Plant in Foshan, Guangdong had a fault with low vacuum.

When the vacuum of the condenser drops, problems such as the continuous rise of exhaust temperature and unit vibration will occur, which will affect the normal operation of the steam turbine, and its influence will be great in a high temperature environment.

No matter what Wholesale CV Joint Suppliers the instrument is, no matter how many advantages the instrument itself has, it is inevitable that large and small failures will occur during long-term work and use, and long-term failures are bound to cause great damage to the components of the instrument. run. Today, we will tell you about the common faults of the auxiliary equipment of the drum gear coupling steam turbine. 

When the rotor is thermally deformed, it will cause the double-frequency amplitude to continue to expand, and when the standby group is started up at a constant speed in cold state, it will cause abnormal vibration of the unit; when there is airflow excitation, there will be a lot of vibrations.

For the poor quality diaphragm couplings produced by some informal manufacturers, it is not only very prone to noise during use. In this process, it is recommended that you must be able to choose a professional and regular team Disassemble instead of disassembling at will.

There were some errors in the installation process of the coupling If someone has some faults during installation and use, this will have some impact on the overall use function, and it is easier to have some dangerous situations, and may even cause problems with mechanical equipment, so if you want to get good use Effective, and to avoid serious noise, it is recommended that everyone should be able to pay attention to reasonable installation, but also need regular maintenance.

As a mechanical product, the coupling sometimes has abnormal noise, so why does the coupling have abnormal noise? What are the reasons? The quality of the coupling CV Joint components Suppliers is not very good This coupling can only exert a stable use effect, and can also meet the needs of various industries. , And will seriously affect its protective effect. The axial offset of the coupling is too large or too small If the axial offset angle of the coupling is very large, or the deflection angle is very small, this will cause shaking during the work, and can not achieve a good anastomosis effect, so usually very serious Sound, in view of this situation is very easy to solve, re-install and select the appropriate specifications of the coupling, so that the application effect can be good, to avoid various failure problems.

The speed code disc of the coupling is faulty If you find that the coupling has a very serious sound, you also need to consider whether the motor speed code disc is malfunctioning, so you have to disassemble it for inspection

An important part of the automobile suspension system is its spherical joint. The ball joint is made of super-hard steel and is the pivot point between the suspension and the car tire. This part helps to support the weight of your car, and like some vehicles, they can be used to help set the alignment. Let us take a closer look at this key component of the car suspension system.

The joint is enclosed in a steel shell and is used in the front end of almost all cars, trucks, SUVs and minivans. It is expected that this important component will suffer a lot of wear and tear, so in order to protect them properly, they are installed in a closed dustcover to prevent dust from entering the joint assembly. There are two suspension systems that use ball joints.

The first is a conventional system using upper and lower joints. The second system is called the MacPherson support system, which uses a single lower joint and upper support bearing. No upper joint is needed because the upper support bearing replaces this work. Over the years, the maintenance of this component in most cars has changed. Many vehicles are equipped with permanently lubricated joints, so lubrication is unnecessary, even because the lubricated components are permanently sealed.

When they are worn or damaged, you can find spare parts that come with the lubrication accessories; in this case, you need to replace the new equipment regularly, as when changing the car oil. When checking the Half Shaft Suppliers car suspension, you should also pay attention to the ball joints. Perform a complete wheel alignment and make sure there is no wear. If they are worn out and have not been replaced, you will soon experience uneven tire wear or unreliable steering (such as drift). Obviously, part wear is a safety issue and must be corrected immediately.
