High quality elbow machine

Hei Yan is specialized in producing complete sets of medium frequency induction machine and High quality elbow machine, bending machine, pipe expanding machine,we have been in the line for more than 10 years.

The High quality elbow machine we manufactured includes two system:

One is induction heating system, using 380V,50HZ three-phase alternating current, through thyristor to convert the frequency, to make 2500HZ medium frequency current, heating the raw material.
The other is hydraulic pushing system, this system can push the heated raw material to the mould end,then form elbows.
Hei Yan also manufacture pipe expanding machine,pipe bending machine,hydraulic press,tee machine,hot induction heating equipment.

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.
