Q:Is polyurethane TPV suitable for sealing products?
The supplier of rubber material, Mr. Chen, reminds you that A polyurethane (TPU) is suitable for sealing (mainly anti-wear and oil resistant). B thermoplastic vulcanized rubber (TPV) application, 1 automobile industry, auto seal, seal series; 2, car cover, fender, ventilation pipe, buffer, corrugated pipe, air inlet pipe; 3, automobile high voltage wire. High voltage 3040KV, can meet the requirements of UL94 V0 flame retardant; consumer products 1, hand tools, electric tools, gardening equipment weeding machine parts; 2, household appliances, washer parts; handle grips 3, scissors, toothbrush, fishing rod, pneumatic equipment, kitchen supplies and other products, cosmetics, beverages, 4; food, bathroom accessories, medical equipment and other products of various types of packaging; soft parts, all 5 wheels, buzzer, pipe fittings, such as belt joint.
Q:How to choose the sealing ring according to the shaft?
General hardness is chosen according to pressure, low pressure with low hardness material, high hardness with high pressure. According to the load type can be divided into static seal and dynamic seal. According to the sealing use, can be divided into hole seal, shaft seal and rotating shaft seal
Q:How about the sealing ring for the piston rod seal?
Previously, the piston rod seals were mostly made of O - shaped sealing rings, narrow section Y - shaped sealing rings and V - shaped sealing rings. Because of the dry friction between the piston rod and the seal, these seals often lead to premature wear of the sealing lip. In the past, the piston rod seals were mostly made of O - shaped sealing ring, narrow section Y - shaped sealing ring and V - shaped sealing ring. Sealed with the sealing structure and common rod which allows ring velocity are relatively low, so it is widely used in motor speed are not high, such as engineering machinery, metallurgical equipment, light industry and agricultural machinery hydraulic equipment.
Q:What is the life span of all kinds of rubber seals?
Your question is a false proposition, the rubber seal life is related to material and working conditions, rubber is a lot of weight, there are fluorine rubber, silicone rubber and so on,
Q:What seals should be used for high speed spindle rotation?
Rotary shaft lip type suggested use is made of fluorine rubber seal (seal fluorine rubber material), resistant to environmental conditions are as follows: -20 degrees -240 degrees, excellent chemical resistance, excellent wear resistance.
Q:What is the international requirement for the temperature of the seal in the hydraulic cylinder?
X ring, rubber ring, rubber ball, Pu seal, seal, pipe joints seals, rubber gaskets and rubber parts. All imported raw materials.
Q:What kind of seals are divided into?
Seals can be divided into two categories: static seal and dynamic seal.Static seals are mainly gasket seal, sealant sealing and direct contact sealing three categories.According to the work pressure, static seal can be divided into medium and low pressure static seal and high pressure static seal. Low and medium pressure static seals are usually made of soft and wide width gasket. High pressure and static seals are made of hard material and metal gaskets with narrow width.
Q:Classification of the use of seals
Seals can be divided into two categories: static seal and dynamic seal. Static seals are mainly gasket seal, sealant sealing and direct contact sealing three categories. According to the work pressure, static seal can be divided into medium and low pressure static seal and high pressure static seal. Low and medium pressure static seals are usually made of soft and wide width gasket. High pressure and static seals are made of hard material and metal gaskets with narrow width. Dynamic seals can be divided into rotary seal and reciprocating seal two basic types. According to the seal of the relative movement of the parts is divided into sealing contact, contact and non-contact seal; according to the seal and the contact position can be divided into circumferential seal and the seal, the seal is also called mechanical seal. The centrifugal seal and spiral seal in the dynamic seal are sealed by the power of the medium when the machine is running, so it is sometimes called the power seal.
Q:The seal of the front end of the cylinder and the cylinder, "O" ring, why has it been serrated for some time?,
It should be the sawtooth at the other end of the pressure chamber.
Q:Does the PTFE seal contain plasticizer? Does the silicone seal require temperature during use?
At the same time, PTFE has the characteristics of high temperature resistance, its coefficient of friction is very low, so it can be used as lubrication, but also become an ideal coating to clean the inner layer of the water pipe.Most of the PTFE material contains plasticizers.
