What is the BMW brake disc replacement standard?

Brake discs are replaced every 100,000 kilometers, which means they are replaced every two brake pad changes. Below are the specific details about BMW brake discs: 1. BMW brake disc thickness: Different BMW models are equipped with different brake discs, with thicknesses of 22mm, 24mm, 26mm, 30mm, etc. The usable thickness for general models is only 2.4mm. For M models or some models using perforated brake discs, the usable thickness is only 1.6mm, equivalent to a 30mm thick brake disc. When it wears down to 28.4mm, it reaches the limit and must be replaced. 2. Usage of BMW brake discs: In terms of brands, BMW uses a variety of brake disc brands. Replacing brake discs, like replacing brake pads, requires a break-in period of several hundred kilometers. During this time, driving should be more cautious as the braking performance may not be optimal.

Where are the 20 points deducted on the ramp?

Starting on a ramp with 20 points deducted may be due to the following reasons: 1. Rolling back less than 30 cm after stopping, deduct 10 points; 2. Failing to turn on the left turn signal when starting, deduct 10 points; 3. The front bumper not reaching the stop line after the vehicle stops, deduct 10 points; 4. The right front wheel being more than 30 cm away from the edge line when parking, deduct 10 points; 5. Stalling, deduct 10 points. Below is more information about starting on a half slope: 1. Starting on a half slope is a test item in the second subject of the driver's license test, which involves starting a vehicle parked on a steep slope upwards. 2. The test requirement is that if the front bumper of the car or the front axle of the motorcycle is not aligned with the pole line after the vehicle stops, and it exceeds 50 cm forward or backward, it is considered a failure.

Is the Driver's Archive Bag Important?

The driver's archive bag is very important. The driver's license archive serves as proof of the entire process from learning to drive to completion. It is highly useful; without the archive, one cannot schedule or participate in the driver's license examination. The driver's license archive records the owner's scores for various subjects, registration information, and medical examination details. Below is an introduction to the contents of the driver's archive bag: 1. Contents: It includes a signed application form by the trainee, medical examination form, training record form, test score sheet, examination appointment slip, skill sheet, and other relevant information. If the archive lacks complete information, the trainee's driver's license will not be issued. For example, missing the trainee's signature or the examiner's approval slip, etc. After the trainee completes all examinations, the archive must be preserved for at least three years. 2. Function: The trainee's archive for applying for a motor vehicle driver's license is kept by the vehicle management office after the trainee passes the examination and obtains the driver's license. This archive is extremely important as it contains records of the trainee's participation in all subject examinations and learning materials. If a new driver is involved in a major traffic accident within three years, the archive will be reviewed for accountability.

What are the six major protection systems of a steam turbine?

The six major protection systems of a steam turbine are: OPC overspeed protection, electrical overspeed protection, mechanical overspeed protection, emergency trip device, reset test valve assembly, and steam turbine trip system. A steam turbine, also known as a steam turbine engine, is a rotary steam power device. High-temperature and high-pressure steam passes through fixed nozzles to become accelerated airflow, which is then ejected onto the blades, causing the rotor with blade rows to rotate and perform external work. Steam turbines are the main equipment in modern thermal power plants and are also used in metallurgical industries, chemical industries, and marine power plants. Electrical overspeed protection: To ensure high reliability of the steam turbine overspeed protection, an independent two-out-of-three signal system is adopted. The system periodically conducts fixed tests. The overspeed protection system has a fast response speed, high reliability, and safety. Mechanical overspeed: Composed of the emergency trip device, emergency trip mechanism, high-pressure trip assembly, and emergency trip linkage. The action speed is 110%-111% of the rated speed (3300～3330r/min). When the speed reaches the set value of the emergency trip device, the flywheel (or flyweight) of the emergency trip device is ejected, striking the latch of the emergency trip mechanism, causing the latch to release. Through the emergency trip linkage, the emergency trip valve in the high-pressure trip assembly is activated, cutting off the high-pressure safety oil supply and releasing the high-pressure safety oil, quickly closing all steam inlet valves and interrupting the unit's steam intake. Emergency trip device: A protection device used to prevent severe overspeed of the steam turbine, also known as the emergency safety (trip) device or overspeed safety device. The emergency trip device is one of the important overspeed protection devices. Reset test valve assembly: In the tripped state, according to the operator's command, the reset solenoid valve 1YV of the reset test valve assembly is energized and activated, introducing lubricating oil into the piston side chamber of the emergency trip mechanism. The piston moves up to the top dead center, and through the linkage of the emergency trip mechanism, the latch of the emergency trip mechanism is reset. Steam turbine trip system: The steam turbine trip system is a dual-channel system connecting electronic protection, overspeed protection systems, and trip solenoid valves. All steam turbine trip commands, overspeed protection systems, electronic protection systems, generator protection, trip buttons, etc., generate shutdown signals, which are executed by the steam turbine trip system to activate the trip solenoid valves and interrupt the unit's operation.
