Do you need to replace two pneumatic butterfly valves for oil leakage in cars
The application of pneumatic butterfly valve in automobiles is well known. If you don't understand, you can also read our previous article! What if your car's pneumatic butterfly valve shows oil leakage? When they sent the car to the 4S store for maintenance, they recommended changing two. Is it really necessary? The pneumatic butterfly valve has been changed. Let's talk about it briefly.
Why is it necessary to replace one pneumatic butterfly valve with another when it leaks oil? The function of the pneumatic butterfly valve is correct. The stability of the whole vehicle plays a very important role. If the pneumatic butterfly valve leaks oil, the stability of the whole vehicle will be affected.
Especially on high speed. Or on uneven low-lying road sections, I feel that the car shakes unstably back and forth. Bad pneumatic butterfly valve Good pneumatic butterfly valve
The two pneumatic butterfly valves will be different from each other. As a result, their tensile forces will be different and unbalanced. Therefore, it is recommended to replace two pneumatic butterfly valves. The service life of the pneumatic butterfly valve is about 80000 km. Compared with the new pneumatic butterfly valve, the oil of the old pneumatic butterfly valve is darker, which is due to the resistance piston inside.
When the leather cups rub the cylinder wall back and forth, the metal chips are generated, which greatly reduces the resistance and affects the operation of the whole car. For safety reasons, if the oil is real, or if it has traveled 80000 kilometers, at least one pair should be replaced, which cannot save money. Otherwise, travel will be affected. However, some riders have bad driving habits. The pneumatic butterfly valve has a problem within 80000 km. What should we pay attention to.
First, drive steadily and slowly on uneven roads, and do not pass through the fuel valve quickly, otherwise it will increase and deepen, and shorten the life of the tensile force of the pneumatic butterfly valve. Secondly, check the shock sleeve of the pneumatic butterfly valve frequently, which plays a key role. If it breaks down, some dust will attach to the rod lubricated by the pneumatic butterfly valve. Into the oil. Changing the pneumatic butterfly valves in pairs will soon break down.
Does the pneumatic butterfly valve of your car show oil leakage? The use of the pneumatic butterfly valve has a certain stability for the whole car. If the pneumatic butterfly valve shows oil leakage, it will have a great impact on the normal use of the car! I believe that the answer to the question of pair change is very clear.

Interpretation of Several Elements of Compensator Selection
There are many factors in the selection of compensators. The following sections will give you a detailed description of how to select compensators. Due to various restrictions, it is quite complicated, but any complex pipeline system can select several fixed supports and different settings at different parts, divide them into several relatively simple single pipe sections, "Z" type pipe sections and "Π" type pipe sections, and confirm the deformation and compensation amount of each pipe section. Because there are many kinds of compensators, Correct model selection is very important, so during the overall design of the pipeline system, full consideration should be given to the design of the pipeline direction and support system (including fixed pipe support, guided sliding pipe support, etc.), as well as the shape and configuration of the compensator, so as to achieve the best combination of safety, rationality, applicability and economy.
Bellows compensator is a flexible element centered on the bellows, which makes axial, transverse and angular compensation on the pipeline.
