2. Operation of the 1200 ton four cylinder elbow pushing machine
Operating procedures are as following:

According to the elbow size select the main pushing pump-- As per the elbow size select the speed -- feeding, close gate --After the mandril been heated to a suitable temperature begin pushing (during working the pushing speed is adjustable) -Reaching the end point ,pushing machine stop automatically- Strobe fix the core rod  -- feeding -- release the strobe, pushing machine return to the end point -- strobe leave the core rod 5mm starting pushing
Except elbow forming machine,hei yan also manufacture pipe bending machine,pipe expanding machine,hydraulic press,medium frequency heating source etc.

Maintenance of machine:

The equipment should be serviced about once a month, maintenance as following:

1.Check each part of fasteners, ensure they are fixed.

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.
