Hydraulic cylinder elbow forming machine

Hydraulic cylinder elbow forming machine adopts medium frequency induction heating, this type elbow forming machine is our traditional manufactured products, production history nearly more than 20 years.

Hydraulic cylinder elbow forming machine is designed and constructed for manufacturing the 45 degree, 90 degree, 180 degree elbows with bending radius of 1.0D, 1.5 and with diameter from 1/2" to 28" of carbon steel and alloy steel elbows,

Hydraulic system is one of the most important part to elbow machine.
Hydraulic system is composed with the following five main parts.
1.Energy device, it provide pressure oil for the hydraulic system, transform the mechanical power into hydraulic power. Normally type is hydraulic pump.
2.Execute device, it transform hydraulic power into mechanical power.Hydraulic cylinder, hydraulic motor, they are all called execute piece of hydraulic system.
3.Control adjustment device, it controls the pressure, flow rate or flow direction of the hydraulic system. I.e overflow valve, throttle valve, reversing valve, start-stop valve etc.
4.Auxiliary device, i.e oil tank, oil filter, oil pipeline etc. They are necessary to keep hydraulic system working well.
5.Working medium, that is hydraulic oil.

2.Make sure that all connectors of the hydraulic pump station are equipped with oil seal rings, if the seal rings appear damaged or oil leakage, should be replace timely.

3.If found forward or backward abnormality, first check electro-hydraulic valve whether operate normal, if working normally, then you should check whether the electro-hydraulic relief valve or the one-way unloading valve has contaminant that made it could not working or not(this phenomenon usually happen when you just use this machine). If has contaminant, you should open it, clean by gasoline or diesl oil, everything is ok, then re-install.

4.Operated this equipment within 15 days, you should clean the tank and filter hydraulic oil once.

5.When cleaning tank, you should clean the inside the oil filter of tank also.
