Q:What are the standard drawing numbers for hydraulic couplings?
The ends of the pipe shall be flush. The pipe should be flush in sawing grinding wheel and other tools, and burr cleaning and blowing with high pressure air before use.When installing, the coaxiality of pipe and joint body should be kept as far as possible. If the pipe deflection is too large, it will cause sealing failure.If the pre loading force is unfavorable, the inner edge of the ambassador card sleeve is just inserted into the outer wall of the pipe, and the clamping sleeve should not be deformed obviously. When the pipeline connection, and then according to the specified tightening force assembly. Phi 6-1 card sleeve tightening force is 64-1 15N, 16 MMR 259n, Phi Phi 18mm for 450n. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.
Q:Is the trachea connected directly to the inside and outside threads? I remember a sealing ring
1. quick installation, simple and smart, space saving 2. forms, to meet the need of any pneumatic pipe arrangement. 3. even after installation, the plastic pipe can be freely turned. The 4. release ring adopts elliptic design, easy to dismount. All 5. taper pipe thread pre coated with Teflon to prevent leakage, good sealing performance.
Q:Hydraulic pipe joint seal, with raw meal belt and sealant that good?
Hydraulic is not high temperature oil, usually with O ring, can not seal the oil, is not the joint surface is not good, can not cut off the replacement of joints, raw rubber tape, sealant is not reliable
Q:Can the pressure vessel pipe joint adopt G thread? Why?
3, pressure vessel, English: pressure vessel, refers to contain gas or liquid, carrying certain pressure airtight equipment
Q:Principle of fast pipe joint
The application with a one-way valve, a one-way valve end is connected with the gas source, when the check valve closes automatically when connected to a one-way valve open end of the thimble.Self locking is the use of steel balls embedded in the groove, while the "cone - cylinder" sleeve to lock the ball.
Q:Pipe joint thread, said in 2 / 3 / 4 points, what does that mean, how to convert ah?,
2 points =2/8, that is, 1/4 inches, and the others are divided by 81 inches =25.4 mmIf it means the thickness of the pipe, it is the British tube of 1/4Indicates that the thread size is the thread of G 1/4
Q:Hot melt pipe joint leakage how to do?
3, with polyurethane waterproof powder (generally used in toilet waterproof), after water transfer brush in the water leakage.4, with weather glue hit in the water leakage.
Q:Hydraulic tubing connections are made of material steel
Hydraulic tubing connections are generally over 20MPa to 40MPa, high pressure multi carbon steel and high strength steel, low pressure useful carbon steel, red copper or brass material
Q:Specification for thread of gas couplings
3, pneumatic connectors, foreign brands are more well-known SMC, domestic brands are commonly used, SNS, TPM.4, pneumatic joints commonly used series are PCH, PCF, PL, PLF, PB, PD, PX, SL, PH and so on
Q:How to distinguish the type of tubing joint?
Corresponding to the different pipe fittings, you should have a good look at the mechanical design manual
