Q:National standard for mechanical seals
activeGB/T 10922-200655 degrees unsealed pipe thread gauge, national quality supervision, inspection and quarantine. Current 2006-08-01GB 11023-1989 high voltage switchgear six sulfur hexafluoride gas sealing test method Ministry of machinery electronics industry 1990-01-01
Q:The difference between piston seal and piston rod seal
The sealing groove should be sealed on the shaft, that is to say, the piston is sealed. The sealing groove is opened on the hole and should be sealed. That is to say, the piston rod is sealed
Q:What's the function of the sealing ring?
Mechanical seal work should pay attention to the problem1, installation notesA, take great care to avoid installation errors in installation(1) to tighten the gland should be aligned in the coupling bolts should be uniform, to prevent the end cap oblique, with feeler check, the error is less than 0.05 mm.(2) clearance check the gland and the shaft or shaft diameter (i.e. concentricity), around to evenly, not more than 0.01 mm check with the feeler the tolerance.B, spring compression amount should be carried out according to regulations, not allowed to have too large or too small phenomenon, requiring 2 millimeters of error. Excessive assembly increases the face to face pressure, and the other speeds end wear. Too little will cause less pressure than sealing.C, the ring should be installed to ensure flexible movement on the axis, the moving ring pressure to the spring, it should automatically bounce back.
Q:Why is there no decent seal for domestic oil seals? What time can Chinese manufacturing resurgence?
Because it is domestic, cheap and convenient, can only be made in china. Import of expensive, there must be a process, but also fewer agents. The export made in China is good. Domestic quality to put up some other, Chinese too fraud, from the Party Central Committee to all civilians in the fraud and adulteration
Q:How should the piston rings for piston wear be chosen? What is the national standard?
Cylinder piston due to long-term reciprocating motion, reciprocating piston seals should be used to require wear-resistant, oil corrosion resistance, hardness is best at about 85 degrees.The choice of sealing ring material is of great importance to its sealing performance and service life. The performance of the material directly affects the performance of the sealing ring.
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 are the main seals used in nuclear power plants?
Nuclear power plants mainly use sealed gaskets, graphite gaskets are used in pipelines, rubber gaskets are used in non-standard equipment. Nuclear grade graphite gaskets require high levels of halogens and sulfur
Q:Reasons affecting the tightness of cylinder
Mainly machining accuracy, the sealing pad between the cylinders also plays a big role. There is the problem of design, basically mature products will not appear airtight problems
Q:How heavy is the mechanical seal of the centrifugal pump?
Simple mechanical seal and double face seal (container type), the weight of a single seal is about 2 kilograms, and the double seal is in the range of 3.5~5 kg.Mechanical seals are one of the most complicated and complex mechanical basic components. They are the key components of various pumps, reaction reactors, turbo compressors, submersible motors and other equipment.
Q:What are the categories of commonly used hydraulic seals?
Polytetrafluoroethylene (PTFE) blocking ring, tube, rod, plate; Polyoxymethylene (POM) guide ring (DM), piston guide ring (LW, SHJ), clamp (K), ring (LDN, LDW); imported rubber (NBR, FKM), polyurethane (PU) of various types of hydraulic materials make the bud ring, drum circle, Yamagata ring, U ring, Y ring, O ring and X ring seal. Products are widely used in a variety of domestic and imported coal mines, the use of hydraulic support, single hydraulic props, emulsion pumps, mining machinery and other hydraulic systems.
