Why does the fuel pump fuse keep blowing?

There might be an issue with the fuel pump, and it is recommended to replace it promptly. Below is some extended information about the fuel pump: 1. The function of the fuel pump: It draws gasoline from the fuel tank and delivers it through the pipeline and fuel filter to the float chamber of the carburetor. It is precisely because of the fuel pump that the fuel tank can be placed at the rear of the vehicle, far from the engine, and lower than the engine. 2. Relay (English name: relay): It is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (excitation quantity) reaches the specified requirements. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is usually used in automatic control circuits and is essentially an 'automatic switch' that uses a small current to control the operation of a large current. Therefore, it plays roles such as automatic regulation, safety protection, and circuit conversion in the circuit.

How to Calculate 10 Days for Booking Subject 2?

10 working days later, you can book Subject 2. Here is the relevant introduction to Subject 2: 1. Basic operations: Subject 2 requires students to master the basic driving operation essentials and possess the basic ability to control the vehicle. Proficiently master the basic methods of driving on the site and on-site roads, have the ability to reasonably use vehicle control components and correctly control the spatial position of the vehicle movement, and be able to accurately control the driving position, speed, and route of the vehicle. 2. Subject 2 test failure: According to Article 37 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses", if the applicant fails the test, they need to first pay the re-examination fee at the vehicle management office. Each subject test can be taken once, and if it fails, it can be retaken once.

How to Solve the Dashboard Reflection on the Windshield?

Solutions to reflection are as follows: 1. Replace the front windshield film to improve its light transmittance: According to national standards, the visible light transmittance of the front windshield and other areas within the driver's line of sight should be greater than or equal to 70%, and no reflective film should be applied to any window glass. Films with lower light transmittance are more prone to reflection. When purchasing, you can also check the labeled light transmittance and reflectivity. 2. Purchase a dashboard sunshade mat: Placing it on the dashboard can prevent reflection. However, sunshade mats have both advantages and disadvantages, and whether to install one depends on personal preference. The pros and cons of sunshade mats are as follows: 1. Advantages: They can prevent dashboard reflection by absorbing sunlight that falls on them. 2. Disadvantages: They prevent dust from falling on the dashboard, making cleaning easier.

Solutions for Hydraulic System Failing to Lower

There are three possible reasons why a hydraulic cylinder fails to lower during its stroke: hydraulic oil blockage in the cylinder, contamination inside the cylinder, or reverse flow in the hydraulic lines. Below is extended information about hydraulic systems: 1. Function: The purpose of a hydraulic system is to increase applied force by altering pressure. A complete hydraulic system consists of five components: power elements, actuating elements, control elements, auxiliary components (accessories), and hydraulic fluid. Hydraulic systems can be divided into two categories: hydraulic transmission systems and hydraulic control systems. Hydraulic transmission systems primarily function to transmit power and motion. Hydraulic control systems are designed to ensure the hydraulic system output meets specific performance requirements. 2. Composition: A complete hydraulic system consists of five parts: power elements, actuating elements, control elements, auxiliary components (accessories), and hydraulic fluid.

Where can I simulate the Subject 1 driving test?

You can practice on various internet websites and mobile apps. Here is some relevant information: 1. There are four subjects in the driver's license test: Subject 2 and Subject 3 are practical driving tests, while Subject 1 and Subject 4 are theoretical test subjects. There is no limit to the number of times you can schedule the theoretical tests. 2. Within the 3-year validity period of the driving skills permit: The number of scheduling attempts for Subject 2 and Subject 3 road driving skills tests cannot exceed 5 times, meaning there are a total of 10 test opportunities for Subject 2 and Subject 3. If you fail the 5th scheduled test, all previously passed subjects will be invalidated. 3. Although there is no limit to the number of scheduling attempts for Subject 1 and Subject 4: This means there is no limit to the number of retakes, but on the day of a scheduled test, you only have 1 retake opportunity. However, Subject 4 can only be taken after passing the Subject 3 road driving skills test. If you fail, you can directly apply for a retake, and the previously passed road driving skills test scores remain valid.

How is overloading a commercial vehicle by one person penalized?

Driving a commercial passenger vehicle exceeding the approved passenger capacity by more than 20% will result in a 12-point penalty; driving a commercial passenger vehicle exceeding the approved passenger capacity by less than 20%, or driving any other passenger vehicle exceeding the approved passenger capacity by more than 20%, will result in a 6-point penalty. The hazards of overloading are as follows: 1. Vehicle overloading severely damages road infrastructure: Due to the load of overloaded vehicles far exceeding the design capacity of roads and bridges, it leads to pavement damage, bridge fractures, and significantly shortens the service life. 2. Vehicle overloading: Increased mass leads to greater inertia, longer braking distances, and higher risks. If severely overloaded, it may cause tire blowouts, sudden deviation, brake failure, rollovers, and other accidents due to excessive tire load and deformation. Additionally, overloading affects the vehicle's steering performance, making it prone to steering failure and accidents. 3. Drivers operating overloaded vehicles: Often experience increased psychological burden and stress, leading to operational errors, affecting driving safety, and causing traffic accidents.
