Q:What kind of equipment do you need to open a small seal factory?
If you don't have any technical support, you can only make some regular products, such as O rings, which are very low in profit.The last one advised you not to do it
Q:Why should the hydraulic cylinder be sealed? Which parts need to be sealed? What are the common sealing rings?
The main purpose of hydraulic cylinder is to push the piston through hydraulic oil to transfer energy to the force body. If the hydraulic cylinder is not sealed, then the two chambers of the tank will be exchanged to form an inner leakage, which will not push the piston to move.Generally in the piston, both ends of the cylinder has a sealing ring (including oil seals and dust).The common sealing rings are O, Y and special sealing rings.
Q:What are the differences between polyurethane TPU and CPU in cylinder seals?
TPU thermoplastic polyurethane elastomer (referred to as TPU)Is a new type of polymeric material between rubber and plastic, in practical application, much as rubber replacement products, also has excellent abrasion resistance and CPU (elastic body most), at room temperature into a solid, heated or solution to make it into a liquid, processing after forming, to become solid polyurethane materials. TPU is one of the most widely used and the largest production of polyurethane elastomer, such as sports equipment: skate wheel, shoe buckle, Internet, accessories, snow boots industrial parts: seal, steam pipe, pipe fittings, accessories (dust damping analysis, industrial wheel, conveyor belt material: air pressure pipe, water pipe medical tube, wire and cable, and a watchband, film, shoe soles, shoe accessories: sheet, cushion, accessories, leather, labels and so on, a day
Q:What is the international requirement for the temperature of the seal in the hydraulic cylinder?
Oil leakage - ~ change a good, try to know, check out whether the seal is in the end!

Q:What are the criteria for choosing the sealing ring type of hydraulic cylinders?
Basically refer to the following criteriaGB/T 10708.1-2000 reciprocating rubber sealing ring structure dimension series first parts: unidirectional sealing rubber (piston seal)GB/T 10708.2-2000 reciprocating rubber ring structure size series, second part, two-way sealing rubber ring (piston rod seal)GB/T 10708.3-2000 reciprocating rubber sealing ring structure size series third parts: rubber dust sealing ring standardOf course, engineering machinery selection of mechanical or other industry standards
Q:How to choose the sealing ring material, sealing ring of different materials, what is the difference?
The silicon rubber sealing ring is also suitable for various articles that have contact with the human body, such as a kettle,Water dispenser, etc.;Not recommendedSILSilicone rubber seals are used in most concentrated solvents, oils, concentrated acids, and sodium hydroxideSIL;Silicone rubber gasketThe general service temperature range of sealing ring is
Q:Mechanical seals do not refuel, can not?
Do you mean mechanical seals or mechanical seals? Where can I get gas? If the medium, you must add the specified medium
Q:What's the difference between the sealing ring shaft and the bore?
Hole is mainly used with outer diameter, can be bigger, not small, the axis of the opposite, with more internal diameter, set on the rod is the axis...... Very intuitive.
