Many owners often have doubts about some driving habits or car functions. They fear that improper operation will affect the service life of the car. They hope that they can get guidance and let cars spend more time with themselves. Chen Yong, a person in this city's auto repair industry, answered some of the questions that were of high concern.
Steering wheel killed affect the steering system?
At present, the power steering system configured on a vehicle can be roughly divided into a mechanical hydraulic power steering system, an electronic hydraulic power steering system, and an electric power steering system.
For the mechanical hydraulic power steering system and the electronic hydraulic power steering system, safety valves are provided, and there is no need to worry about the hydraulic pump being hurt by the steering wheel. In addition to the design of the safety valve, a limit device is also designed on the steering mechanism, that is, even if the steering wheel is killed, the damage to the steering system cannot be achieved.
The electric power steering system does not have a hydraulic pump as a component. Instead, it is an electric motor. The computer-controlled steering system is more sophisticated in terms of safety protection functions, and there is no need to worry about this problem.
Parking wheel does not damage the steering system?
When many novices are parked, they often cannot grasp the wheels to correct themselves. Sometimes the front wheels are locked and they are directly locked out. This is indeed a bad habit of parking, which will damage the steering system of the vehicle in the long run. When people drive, after turning the steering wheel, they feel that the steering wheel has a positive back force, because the steering lever is under stress. The parking steering wheel does not return to the correct position, and the wheel will always pull the internal pull rod, causing wear over time.
The steering wheel does not return to normal when it is parked. Apart from minor wear on the vehicle components, there is a potential hazard that when the car is started next time, if you step on the accelerator directly, you may encounter the next vehicle.
Automatic start-stop function damages the engine?
With the continuous improvement of car configuration, more and more models have been equipped with automatic start and stop functions. However, some owners have been skeptical of this function. They feel that starting and stopping the engine frequently will affect the service life of the engine.
Most of the wear of automotive engines comes from instantaneous wear during cold start, and the automatic start-stop function imposes restrictions on the engine's temperature and ambient temperature. This function will not work when the engine temperature does not reach the proper start-stop temperature. Only when the engine temperature reaches a certain value, the automatic start and stop function will work, then start the engine is called hot start. And the automatic start-stop time is often not very long. The engine oil that is attached to the inner surface of the engine block by the oil pump will not completely flow back, and the parts still retain a lot of engine oil. In the case of a warm start, there will be no impact on the engine.
At present, most automotive companies have done a full tolerance test when launching an automatic start-stop system. The number of switches used in related devices such as engine ignition switches and starters is also much lower than the theoretical life value. Therefore, the engine start-stop device will not damage the vehicle's engine.
Plate And Frame Heat Exchanger
Removable Plate Heat Exchanger (RPHE) is a type of heat exchanger composed of a series of plates which are held together with gaskets. The plates are connected in a plate pack that forms a sealed Pressure Vessel. The plate pack is assembled between a fixed frame plate and a movable pressure plate and is compressed by tightening bolts.
RPHEs are quite efficient as they have a large surface area compared to other heat exchangers. Heat transfer within the heat exchanger occurs between the plates and the fluids that flow through them. One fluid flows through the plate openings in each of them, and the heat transferred is determined by the size and number of plates in the exchanger. The heat -exchanging process is repeated in each of the plates and the collected heat is transferred to the other fluid.
Plate and Frame Heat Exchangers have proved beneficial in the food and beverage industries where they are used to maintain a safe temperature during the processing and storage of foods. In addition, they are used in chemical manufacturing to cool the various chemicals that are used in this industry.
