How to deal with the noise problem of old cars by electric butterfly valve manufacturers
There are many people who own cars. They are too shy to buy a new car. They can also choose to buy a second-hand car. But how can we deal with the noise problem of second-hand cars! Electric butterfly valve or a good choice! I will analyze the cause of noise for you!
Exhaust pipe noise: it belongs to the category of normal aging. For the exhaust pipe with a length of 10 years or 200000 km, the noise at the rear of the car body will be increased because the bottom of the car body is often exposed to acid and alkali mixture such as mud and water, or there is the possibility of air leakage due to corrosion, which can be heard clearly. The treatment method is to replace the whole or local exhaust pipe, and the noise can be eliminated immediately.
Noise of engine and its accessories: This is caused by normal wear of internal components of the engine due to age. If there has been an abnormal accident before, for example, the engine oil has leaked out and has not been found in time, or the antifreeze has leaked out. The engine with such experience will be more noisy, and its noise will be different regardless of the size of the accident. The treatment is to replace partial or all engine moving parts, such as connecting rod, connecting rod bush, piston and piston ring. It is also caused by incorrect or worn accessories such as some belts outside the engine.
Brake system noise: if the brake pads continue to be used after normal wear, the brake shoes will easily rub the brake disc (that is, the phenomenon of iron hitting the iron), which will cause a very harsh squeal when braking. The treatment is to change the brake pads (if the brake disc is worn, it should also be changed).
Noise of suspension system: although it belongs to the normal aging category, different users will have significantly different results. A large part is caused by the wear of hub bearings or the reduction of damping ability of valve fluid in electric butterfly valves. There are also many examples of valve fluid leakage. Since the valve performance of the car is achieved by valve fluid and butterfly valve, the loss of valve fluid talent will significantly increase the noise. The treatment is to go to the car shop for repair, replace the hub bearing or electric butterfly valve, etc.
