The hydraulic machine is large in size and heavy in weight; it is constrained by various processing conditions such as casting, casting, cutting, and equipment; therefore, the accuracy of the press itself cannot be completely ensured by the machining itself; Adjust in to reach its accuracy targets.
The adjustment is based on the specific requirements of the SKF imported bearing accuracy test; the accuracy and stability of the precision and stability depends on the pre-tightening and anti-loose methods and methods to ensure the hydraulic machine used in all walks of life; because of its usefulness Different requirements for the accuracy of their operations are also different; in the production production also follows different professional norms. In the same occupation because the production products are not the same; the accuracy of the demand is not likely to be common. Therefore, the same occupational norms do not work the same It is divided into several grades and corresponds to each precision target. In the factory production, the technical department prepares the inspection outline and the test plan according to the accuracy specification of the production press; the relevant department is issued as the guiding document; the relevant rules and measures for the detection of the items and parameters And corresponding data; as a specification for device adjustment and inspection.
It usually includes the precision items that need to be adjusted in the process of SKF imported bearings. For example, the level of the workbench in the hydraulic press, the column distance error, the flatness of the workbench and the movable workbench, and the upper and lower beams connected to the column. The straightness, the parallelism between the worktables, the straightness of the main cylinder in the working stroke and the straightness of the workbench, the touch rate of the surface nut fitting surface of the column and the upper and lower beams, etc. SKF imported bearing precision adjustment and detection Process and results; only after the full-time staff approves the signature, the necessary items and tooling in the process of inspection and adjustment are drawn by the professional craftsmen in the production process, and then compiled into the production process according to the plan. Inspection outline and inspection adjustment operation Save it.

Alloy Steel Pipe

Alloy pipe is a kind of Seamless Steel Pipe, which is divided into seamless pipe for structural use and high pressure heat resistant Alloy pipe.Different from the production standard of alloy pipe and its industry, the mechanical properties of alloy pipe are changed by annealing and tempering to meet the required processing conditions.Its performance is higher than the general seamless steel tube's variable utilization value, the alloy pipe chemical composition contains more Cr, high temperature, low temperature and corrosion resistance performance.The general carbon seamless pipe does not contain the alloy composition or the alloy composition is little.

Application

Alloy tubes are more widely used in petroleum, aviation, chemical, electric power, boilers, military industries and other industries because their mechanical properties are more variable and easy to adjust.
