Q:What type of sealing roller bearings.
1, bearings, lubricants and types (grease and lubricating oil);2, bearing work environment, the size of space;3, the supporting structure of the shaft has the advantage of allowing angular deviation;4, the circumferential speed of the sealing surface;5, the working temperature of the bearing;6, manufacturing costs.
Q:Classification of sealing strip by use
Table 29.2-1 classification of sealsThe basic requirements of the seal is the sealing is good, safe and reliable, long service life, should be compact in structure, simple system, convenient maintenance, low cost, most of the seal parts, should ensure interchangeability, realize standardization and seriation.Various types of by sealing group leader have their characteristics and scope of use, the design of sealing should first be analyzed and compared.Table 29.2-2 lists the characteristics of a variety of commonly used sealing methods. Table 29.2-3 is the type and range of applications of dynamic seals.Sealing type, reciprocating motion, rotation, pressure resistance, high speed resistance, heat resistance, cold resistance, durability, remarksPacking seal pump, turbine, valve, autoclave. Available for filament packing, textile packing, or molding.O - ring seal piston seals are widely used as static seals, with good durability at this time.
Q:What are the requirements of bearings for sealing?
Non contact seals include axial curve seals, radial bend seals, oil groove seals, retaining rings, seals, etc.
Q:How are ceramic and metal sealed joint?
If it is static sealAxial, O ring or flat gasket can be used; radial O ring can be used.If it is dynamic seal, in addition to radial seal, but also consider whether the need for axial dust ring.The end face seal has a special sealing ring, and the lip is contacted with the ceramic surface.For reciprocating motion, a combination of O rings or other cross sections can be used.
Q:Why is there no decent seal for domestic oil seals? What time can Chinese manufacturing resurgence?
Ha ha, now the high-end sealing products are basically occupied by foreign brands, NOK, Parker, good Wright, and so on. But now Taiwan seals are very expensive, you can choose Taiwan seals as an alternative,
Q:What are the criteria for choosing the sealing ring type of hydraulic cylinders?
Hello I do hydraulic seals!Selection of sealing ring for hydraulic cylinder:1. depends on whether you need the sealing ring, shaft or hole.2. see if the sealing ring you need is groove type or press plate type
Q:How long will it take for the seal to age naturally after the seal has been installed on the cylinder?
This question you can consult their agents, my personal opinion is: 1. sealed packaging storage; there is no need to not open the package; 2., placed in a cool and dry place, away from the heat source! The failure of sealing ring, will change color or blooming phenomenon!
Q:What kind of seals are divided into?
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:All the seals in the car engines, especially those sealed in the cylinders.
Before and after the crankshaft oil seal, valve oil seal, camshaft seal, valve cover gasket, oil pad, cylinder gasket, oil pump gasket, oil cooler oil filter gasket, cushion and so on, what's the problem?
Q:What's the difference between an oil seal and a seal? Is it the same thing?
Broadly speaking, seals include oil seals. In a narrow sense, it can be understood that seals can be used to seal oil or to seal air, i.e., oil seals and pneumatic seals. But in the sealing field, oil seal is used for rotating the skeleton oil seal, and non professional fields, such as some used seal factory engineers, said the oil seal is used to seal oil seal, including static seal and reciprocating rotary oil seal oil seal and seal oil seal.
