Q:What kind of seal is the dust sealing ring?
Material features of dust ringNow most of the dust ring is formed by rubber material processing, the material dust ring is the biggest characteristic of dry friction, hence the need for the rubber material has excellent wear resistance, and low compression permanent deformation. In recent years, dust and other materials seal slowly up, such as PTFE and O ring combination, its sealing effect is very ideal, but you can use a long time, now the place is more and more.
Q:What type of sealing roller bearings.
The seal can be divided into two categories with seal and seal with roller bearings. The so-called bearing comes with sealing, that is, the bearing itself is made into a sealing device. Such as bearings, dust cover, sealing ring and so on. The utility model has the advantages of small space occupation, convenient installation and disassembly and low cost.
Q:What equipment is needed to produce rubber seals and what is the production process?,
Hello I made the seal! You do rubber ring to do large-scale (mixer, pre forming, opening machine, cutting machine, vulcanizing machine, trimming machine, testing equipment, there are many, I will not say!
Q:What are static seals and dynamic seals?
In O type rings, the main performance is that their compression ratio can not be the same, and the groove size design can not be the same, in the case of pressure, the dynamic seal need to increase the hardness, or even use the retaining ring. According to the use of the situation, the dynamic sealing requirements of the O ring strict workmanship. In terms of material, it is only determined by working conditions.
Q:What are the equipment needed to produce the sealing ring?
It's easy to see things done by others, but when you really get into it, it's not the case. You don't know about the multi-level sealing ring is what is known as the king of PTFE tetrafluoroethylene, plastic. Are you going to make a vinyl sealing ring?
Q:How to prevent the metal from sticking to the gasket?
It is better to use torque wrench when sealing gasket is pressed. For large bolts and high strength bolts, it is better to use hydraulic tightening devices. The tightening torque shall be calculated by calculation according to the given gasket. The size of the hydraulic pressure of the hydraulic tightening device shall also be determined by calculation.5. When installing the gasket, tighten the nut in sequence. However, the design value should not be screwed once. Generally should be recycled at least 2~3 times so that the gasket can be evenly distributed.6, the flammable and explosive medium pressure vessel and piping, replacing gasket should be used to avoid security tools, tool and flange bolts or collide, sparks, causing a fire or explosion accident.
Q:Sealing type and specification of solenoid valve core
The form of the spool is globe, V-ball, hemisphere, butterfly valve plate and other types.The form of the valve must be selected according to the characteristics of various valves, the general will use the plunger valve.
Q:Seal type of transformer oil tank
The seal type of transformer is oil pillow type.Reasons for leakage of transformer oil:1, general seals are life, because the seal is made of rubber materials, rubber in the environment will gradually aging, the aging of rubber lose their elasticity, also lost its sealing performance. My experience is that the life of a general rubber seal is 3-5 years.
Q:What are the differences between polyurethane TPU and CPU in cylinder seals?
It is divided into casting polyurethane elastomer (referred to as CPU), thermoplastic polyurethane elastomer (referred to as TPU), and mixed polyurethane elastomer (MPU).CPU- is a castable polyurethane elastomer (CPU)
Q:What are the storage conditions for seals?
Storage conditions for general sealsAvoid high temperature: preferably at 30 degrees Celsius, to avoid sealing high temperature agingAvoid air and dust: it must be stored in a sealed package to avoid contact with moisture and dust in the airAvoid glare: avoid light exposure, prevent the seal from being airborne ozone or premature aging. The performance of various sealing factors are different, such as mechanical seal (packing seal), the influence factors are temperature, medium, wear, pressure and so on
