Can a Leaking Car Condenser Be Repaired by Welding?

Car condenser leaks can be repaired using gas welding. Below is relevant information about automotive air conditioning systems: Automotive air conditioning structure: Typically consists of the compressor, electromagnetic clutch, condenser, evaporator, expansion valve, receiver-drier, piping, condenser fan, vacuum solenoid valve, idle speed controller, and control system. Compressor operating range: Under normal conditions, when the compressor operates at 1500-2000rpm, the high-pressure side maintains approximately 1.5-2.0MPa while the low-pressure side remains around 0.15-0.35MPa. In high ambient temperatures, high-pressure readings may reach 2.5-2.8MPa, though generally not exceeding 3.1MPa.

Which Vehicle Management Office to Go for License Plate Registration in Yanjiao?

Go to the Yanjiao Vehicle Management Office. Here are the precautions for new vehicle license plate registration: Note the exemption policy: Although imported motor vehicles and some domestic cars, small and mini passenger vehicles have been included in the exemption scope, the number of domestic car models exempt from inspection is relatively small. After the implementation of the new policy, all domestic cars can be exempt from inspection. The exemption scope for new vehicles includes cars and small, mini passenger vehicles and two-wheeled motorcycles marked with "new vehicle exempt from inspection." Exempt models: This does not include off-road vehicles, small and mini ordinary passenger vehicles, or heavy and medium-sized trucks. Exemption does not mean direct license plate registration: The exemption for new vehicles does not mean you can go directly for license plate registration. Currently, it only eliminates some items of the on-line inspection. New vehicles must still undergo appearance inspection, photo-taking, and number stamping at the inspection site before license plate registration. In addition, the tail gas inspection required for environmental protection must still be conducted.

How Long Can a Car Air Conditioner Be Turned On?

It is advisable to turn on the car air conditioner for about 15 minutes at a time. Prolonged use can lead to poor heat dissipation and damage to the car engine. In relatively enclosed environments, such as garages, it may cause carbon dioxide poisoning. It's best to use the air conditioner in open or well-ventilated areas and leave a slight window gap. When the car is idling, the engine operates at a lower speed, resulting in lower intake pressure. In this state, the engine increases the throttle opening, thereby increasing fuel injection. Shortly after entering the car, you should open the windows or activate the external circulation ventilation system to introduce fresh air. Avoid driving for extended periods with closed windows and doors, and never sleep or rest for long durations in a sealed car. As oxygen levels gradually decrease in the enclosed space, occupants may experience dizziness, nausea, and general weakness over time. Maintain air exchange between the inside and outside of the car: After purchasing a new car, it's essential to facilitate air exchange between the interior and exterior, similar to ventilating a newly renovated house, to allow harmful gases inside the car to dissipate as quickly as possible. Regularly clean the car's air conditioning system: If not cleaned for a long time, bacteria can proliferate within the system, posing health risks to passengers.

What Causes the Clicking Sound When Starting an Electric Tricycle?

The reasons for the clicking sound when starting an electric tricycle are as follows: Controller malfunction: The controller is the main device that controls occasional commutation. When the controller is damaged (mainly due to internal control program disorder or loss), the electric vehicle will make a clicking noise during startup and riding. In this case, it is necessary to replace the controller with the corresponding phase angle and brake level, or replace it with a Hall-less self-learning type controller. Throttle handle malfunction: According to electric tricycle manufacturers, when the throttle handle has poor contact or the internal Hall performance deteriorates, the electric vehicle will make a clicking noise during startup and riding. At this time, you can use the DC voltage range of a multimeter to measure the voltage between the Hall signal line and the negative pole, and the value varies depending on the throttle handle and controller.
