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 considered that the gap between the two mounting surfaces of the 0 type ring is too large.It is recommended to reduce the fit clearance or increase the retaining ring.
Q:In the automotive seals company is not a permanent solution to the health
Sealing enterprises are mainly vulcanizing workshop smell. But now some enterprises of the production of professional protection of employees do very well, negative pressure workshop, airtight machinery, the smell will not be great.
Q:Classification of sealing strip by use
Y ring seals, piston seals, sometimes static sealsMechanical seals, pumps, turbines, high pressure vessels, compressors, agitation. A combination of different materials, including metal bellows seals, can be usedThe oil seal is sealed or sealed with other seals, and dustproofSplit slip ring seal, hydraulic turbine, steam turbine, multipurpose graphite, slip ringLabyrinth seal steam turbine, pump, compressor reciprocating, should be high speed, low speed do not useFloating ring seal pump and compressorCentrifugal seal and screw seal pumpThe magnetic fluid sealed compressor is only used in gas mediumTable 29.2-3 types and applications of dynamic sealsVacuum pressure (absolute pressure) /MPa (g) /MPa / C working temperature line speed of /m - S-1 / M - H-1 leakage rate using the term applicationPacking sealing 1.33 * 10-3, 31.38 -240 ~ 6002010~1000 - clean centrifugal pump, plunger pump, valve stem sealContact forming packing, extrusion type, 1.33 * 10-7, 98.07 -45 ~ 230100.001 ~ 1 ~ 0.16 months hydraulic cylinder, hydraulic cylinderLip type 1.33 x 10-9 0.1 to 10Rubber oil seal - 0.29 -30 ~ 150123~6 months bearing sealing and dust-proof
Q:How should the piston rings for piston wear be chosen? What is the national standard?
Material applicationNBR NBR sealing ring: suitable for use in petroleum system, hydraulic oil, glycol hydraulic oil, two ester lubricating oil, gasoline, water, silicon grease, silicone oil and other media. It is the most widely used and lowest cost rubber seal at present. Not suitable for polar solvents such as ketones, ozone, nitro hydrocarbons, MEK and chloroform. The general use temperature range is -40~120 degrees centigrade.
Q:The function and principle of cooling water for mechanical seal of water pump?
For mechanical seal water, first of all, you should understand the structure of the mechanical seal, mainly by grinding between the static and dynamic ring seal
Q:How to prevent the metal from sticking to the gasket?
Gasket and flange sealing surface should be cleaned, must not have any influence on the sealing performance of scratches, spots and other defects exist.
Q:What rubber kind of rubber does the brake seal of the car use?
The synthesis of liquid to polyethylene glycol or glycol and boric acid ester, because this "oil" may mislead him. Second, the brake should be used three yuan synthetic liquid ethylene propylene rubber (EPDM), which is resistant to chemicals because of the elementary concentration. He used EpDM production after swelling qualified, is very happy.The production of rubber products is important for the accumulation of knowledge
Q:What's the seal water? What about the water seal?
Seal water is to pump the water seal way, in operation the seal water pressure difference, mainly depends on the seal water to enter the water pipe's seal water control valve to carry on the automatic adjustment. The seal groove is arranged in the ash bucket of the lower box, the lower part of the length of a steel plate. Steel plate with displacement in the header, but still not out of the water, this is the one hand to ensure the water wall expansion free, and ensure good sealing process of expansion.
Q:Differences and connections between fasteners and seals
In general, we are divided according to materialOr directly defined as mechanical components
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?
