How can I check whether my shock absorber fails?
In the past, pneumatic butterfly valves have become more and more common in life and consumption, and their applications are also very common. Then, pneumatic butterfly valves are mainly used to suppress the shock when the spring rebounds after shock absorption and the impact from the road surface. Pneumatic butterfly valves have a lot to do with warmth. So in ordinary daily maintenance, we often see that the shock absorber is invalid or not working well, At this time, we should learn some simple identification methods to determine whether they can be used. Today, Songxia pneumatic butterfly valve manufacturer will analyze the failure certification tips for pneumatic butterfly valves.
After confirming that there is a problem or failure of the shock absorber, check whether the pneumatic butterfly valve can leak oil or has traces of obsolete oil leakage. The oil seal washer and seal washer are broken, and the nuts of the oil storage cylinder cover are loose. The oil seal and sealing washer may be damaged and invalid, so the seal shall be replaced with a new one. If the oil leakage still cannot be eliminated, the shock absorber should be pulled out. If it feels stuck or different in weight, further check whether the clearance between the piston and the cylinder barrel is too large, whether the piston connecting rod of the shock absorber is bent, and whether the surface of the piston connecting rod and the cylinder barrel are scratched or pulled.?

Use "pneumatic butterfly valve" to set up a bridge to ensure nitrogen sealing effect
The tapping operation of converter is the most important link in the steelmaking process. The entire tapping process requires operators to check and grasp the opportunities and positions of alloy and carbon powder participation from time to time, so as to improve the absorption rate of alloy and carbon powder and control the end composition, which is usually called "end point control and deoxidation alloying".
In the tapping process, because the alloy participates in the ladle and immediately reacts with the molten steel, a large amount of smoke and dust and open fire will be generated, which will burn the hardware equipment of the alloy rotary feeding system, and at the same time, it will cause certain unsafe factors to personnel. In order to prevent this injury and ensure the nitrogen sealing effect, the maintenance personnel installed nitrogen pipes on the inner wall of the blanking pipe, that is, to seal the flame and smoke, so that it will not come up from the alloy rotating blanking pipe, thus achieving the nitrogen sealing effect during tapping. It can be found during operation that the wear of alloy block will cause great wear to the nitrogen seal and the inner wall of blanking pipe, which requires repeated repair welding with poor effect. Repair welding is required after half a month at most, and the original nitrogen sealing effect is lost.
In order to understand and solve this problem, the work section encouraged personnel at all levels to innovate and work together, and held a special meeting to discuss countermeasures. After concerted efforts, the converter section found a good plan, that is, to make air pipe interface at the mouth of the alloy rotary chute seat, and connect the air source with the pneumatic butterfly valve. In this way, the air pipe interface will rotate with the chute, preventing friction with the alloy block, reducing equipment damage rate, and lasting nitrogen sealing effect.
