China Elbow forming machine has uniform stress, compare with two cylinders big pushing force Elbow machine, it is lower cost, reasonable design. Hei Yan Four cylinder Pushing Elbow Forming Machine saves cost for customers and it is good asset to enterprises.

China Elbow forming Machine has following functions :auto mandrel adjustment,auto clamp,also insert board. Operating is easy ,with Elbow machine,working efficiency can be raised.

Pump station is combined by stage pumps,due to different flow out,it has 2-4 stages. The first stage is empty running,fast pushing,fast return. Hei Yan technician are doing deep researching,there are lots of improvment. I.e. Generators below of oil tank in order to heat dissipation.China Elbow forming machine has high working efficiency.

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.
