Lan Cheng Yu pipeline remote cut-off valve test was successful

August 30, 2024

At the end of December 2005, the Langfang Control Center of the pipeline company succeeded in carrying out a series of tests on the remote emergency cut-off valves and SCADA control systems of the Lancheng-Yu pipeline, which marked the further improvement of the pipeline companies' control over the pipelines under their jurisdiction. Passed the test to improve the reliability of Lan Cheng Yu pipeline control, testing various control functions of SCADA system to further rationalize the operation plan.

Machinery shell with gearbox shell processing
Machinery for typical gearbox shell body parts, main processing plane and hole system, to ensure that the size of the hole in the process of machining precision and position accuracy, handle the relationship between hole and plane. Should follow the principle of surface before hole, namely first processing box on the datum plane, and then to datum plane positioning processing other plane, then processing hole system. Because of the planar area is large, with its positioning can ensure reliable positioning, clamping and firm, and therefore easy to guarantee machining precision holes. Secondly, cut off the casting surface uneven, create conditions to improve the machining precision of holes, facilitate and adjustment of the knife, is conducive to protect the cutting tool. Processing technology should also follow the principle of separate rough finish machining.
