Malfunctioning solenoid valves can lead to various issues, such as gear shifting jerks, slippage, gear engagement shocks, and inability to upshift. Extended information: Criteria for solenoid valve selection: 1. Selecting solenoid valves based on pipeline parameters: nominal diameter (i.e., DN), connection method. (1) Determine the nominal diameter (DN) size according to the on-site pipeline inner diameter or flow requirements; (2) Connection method: generally, for >DN50, flange connections should be chosen, while ≤DN50 can be freely selected based on user needs. 2. Selecting solenoid valves based on fluid parameters: material, temperature group. (1) Corrosive fluids: It is advisable to choose corrosion-resistant solenoid valves and those made entirely of stainless steel; for ultra-clean food-grade fluids: food-grade stainless steel solenoid valves should be selected; (2) High-temperature fluids: Solenoid valves made with high-temperature-resistant electrical materials and sealing materials should be chosen, and the piston-type structure is preferred; (3) Fluid state: Generally categorized into gaseous, liquid, or mixed states, especially for diameters greater than DN25, it is essential to distinguish between them; (4) Fluid viscosity: Typically, any choice can be made for viscosities below 50cSt, but if the value exceeds this, high-viscosity solenoid valves should be selected.

Can a newly purchased car be driven on the road without license plates?

A newly purchased car cannot be driven on the road without license plates. Here are the precautions to take after buying a new car: 1. No driving without a license: You can buy a car without a driver's license, but you cannot drive the car on the road after purchase. Driving without a license is illegal. 2. License plate instructions: When registering a car after purchase, the driver's license will not be checked. After purchasing a new car, you will need your ID card, vehicle certificate, purchase invoice, tax payment certificate, insurance policy, etc. to register the car. At the vehicle management office, staff will inspect the vehicle and take photos. After the car is registered, the owner will receive the vehicle registration certificate and the vehicle license. 3. The vehicle license must be carried with the car: When driving, you need to carry both your driver's license and vehicle license. During the probationary period, you are not allowed to drive on highways.

What are the minimum and maximum speed limits on highways?

Highways have a maximum speed limit of 120 km/h and a minimum speed requirement of 60 km/h. Precautions for novice drivers on highways: 1. Maintain safe distance: Following distance is the primary factor for driving safety. Many inexperienced drivers often misjudge distances due to lack of experience. If following too closely, there won't be enough time to brake in case of emergencies. 2. Speed limits: Unlike regular roads, highways have strict speed regulations. While driving slightly slower is acceptable for beginners, never go below the minimum speed limit - according to traffic laws, driving below the posted minimum speed on highways results in a 3-point penalty. 3. Avoid sharp steering: Always keep both hands firmly on the wheel at high speeds. When changing lanes or overtaking, make gradual turns to prevent skidding. For braking, apply the brakes progressively in several stages rather than slamming them suddenly to avoid losing control.

Can You Wear High Heels While Driving a Car?

Driving should not be done while wearing high heels. Wearing high heels while driving can lead to improper control of the accelerator or brake pedals, compromising driving safety. During emergency braking, high heels are prone to twisting and getting stuck in the brake pedal, which can cause brake failure and easily lead to foot injuries. High heels can also affect the movement of pressing the accelerator and brake pedals, potentially causing the foot to slip off the pedal due to excessive force. Avoid Driving While Fatigued: Ensure you get enough sleep to stay alert. If you feel drowsy while driving, pull over promptly and take appropriate rest. Proper Use of Sunglasses: When choosing sunglasses, avoid those with overly dark lenses. Opt for polarized sunglasses instead, as they can filter out harmful light. Avoid Wearing Flip-Flops: During hot summer weather, feet tend to sweat more. In the event of an emergency while driving, wearing flip-flops can easily lead to dangerous situations.

Is 90 Degrees Normal for Coolant?

Normal, the standard operating temperature is 90-95°C. Causes of overheating coolant: 1. Fluid leakage or insufficient coolant: Leakage in the cooling system can lead to insufficient antifreeze, causing the antifreeze temperature to rise. If the antifreeze level is found to be low, the first step is to check for leaks. If there are no leaks, promptly add the same type of antifreeze. Do not add tap water or other types of antifreeze to avoid dilution or sedimentation, which may cause failure or malfunction. 2. Cooling fan failure: A malfunctioning cooling fan can prevent timely dissipation of heat generated by the engine during high-speed operation, leading to an increase in antifreeze temperature and issues like "boiling over." While driving, always monitor the antifreeze temperature. If abnormalities are detected, reduce speed and stop the vehicle, but do not turn off the engine. Check whether the cooling fan and circulation water pump are functioning properly.

What is a lane with spikes?

A lane with spikes is called a tidal lane, also known as a variable lane. Here is the relevant introduction to this lane: 1. Purpose of setting: The purpose of setting is to solve the problem of vehicle flow at intersections where tidal phenomena are more serious. At an intersection, the straight-through traffic flow is relatively large during the morning peak, while the left-turn traffic flow is relatively large during the evening peak. This difference in traffic flow between morning and evening peaks is called the tidal phenomenon. This lane can change the direction of travel according to the change in traffic flow, thereby improving traffic efficiency and alleviating traffic congestion. 2. Precautions: When encountering such a lane, be sure to pay attention to the signs or traffic lights to determine the direction of travel. If you enter this lane without determining the direction of travel, you may violate traffic rules.

Is fingerprinting required for Subject One exam?

Fingerprinting is not required for the Subject One exam, only a valid ID card is needed. Please note that expired ID cards cannot be used. The total duration of the Subject One exam is 45 minutes. The test paper consists of 100 questions, including true/false and single-choice questions. The exam papers are randomly selected and combined by the computer-based driver examination system according to the proportion specified in the "Motor Vehicle Driver's License Work Regulations". Subject One exam content: The exam content includes the most fundamental knowledge such as driving theory basics, road safety laws and regulations, traffic signals, traffic rules, plus local regulations. The scheduling of the theoretical driver's test is arranged independently by local vehicle management offices. Subject One exam precautions: Bring and present your ID card for verification by the supervising officer; mobile phones must be turned off when entering the exam area; no loud talking is permitted in the exam area; theory textbooks are not allowed in the examination room (or should be kept in your bag).
