Materials for making hydraulic universal tester oil cylinder

Jinan Testing Machine Factory Share ProductionHydraulic universal testing machineWhat material is used in the oil cylinder generally depends on where we are going to apply. The materials we use for hydraulic universal testing machines with different working pressures are also different. When making, consider whether they can adapt to the working pressure environment!

Ji'nan test machine share what material hydroulic universal testing machine cylinder is used,to see what we should be applied to different places, the working pressure of the hydroulicuniversal testing machine, our material is not the same, in the production should consider when can adapt to work pressure environment!

First of all, hydraulic universal testing machines with excessive loads are commonly used in some heavy industry enterprises. Due to the high working pressure, this hydraulic universal testing machine is often made of seamless steel pipe materials of No. 20, No. 35 or No. 45. Among them, the No. 20 seamless steel pipe material is rarely used now because of its low mechanical properties and cannot be tempered. The cylinder block that needs to be welded with the cylinder head, pipe joints, trunnions and other parts can be made of No. 35 seamless steel pipe material and is tempered after rough processing. The cylinder block connected to other parts can be tempered with No. 45 steel to the HB241 to 285 range.

At first, some enterprises use large heavy load hydroulic universal testing machine, the hydroulic universal testing machine with high working pressure, often with No. 20, No. 35 andNo. 45 seamless steel tube material. Among them, 20 seamless steel tube material, because of its lower mechanical properties, and can not be quenched and tempered, is now rarely used. Need to joint, and cylinder head, tube parts such as cylinder trunnion welded together, making available 35 seamless steel tube material, and quenching and tempering in the rough machining. With the threads of the cylinder body and other parts link, can adopt 45 steelquenched and tempered to HB241 to 285 range.

Then, for hydraulic universal testing machines with low working pressure, high-strength cast iron can be used to make oil cylinders; for hydraulic universal testing machines with high working pressure, seamless steel pipe materials can be used to make oil cylinders.

So for the hydroulic pressure lower universal testing machine can produce cylinder made of cast iron with high strength; high working pressure for hydroulic universal testing machine, can make the oil cylinder adopts the seamless steel tube material.
