Mechanical seal components and their associated assembly contact surface, before installation must be cleaned with acetone or anhydrous alcohol. During the installation process should be kept clean, especially moving, stationary ring and auxiliary sealing elements should be free of impurities, dust. Dynamic and static ring surface coated with a layer of clean oil or turbine oil.
　　
Tighten the gland should be corrected after the coupling. Bolt should be tightened evenly, to prevent the gland section deflection, with feeler or special tools to check the points, the error is not greater than 0.05 mm. Check the gland and shaft or sleeve diameter with the mating gap (and concentricity), we must ensure that the surrounding uniform, with a feeler to check the tolerance of each point is not greater than 0.10 mm.
　　
The amount of spring compression to be carried out according to regulations, not allowed to have too large or too small, the required error of ± 2.00 mm, over the General Assembly to increase the section pressure, accelerate section wear. Too small will cause the pressure is insufficient and can not play the role of seal, the spring installed in the spring seat to move flexible. With a single spring to pay attention to the direction of rotation of the spring, the rotation of the spring should be the opposite direction of rotation of the shaft. After the installation of moving ring to maintain flexible movement, the moving ring should be able to automatically spring back after the pressure to the spring.
3 axis machining implies that the workpiece remains in the same position while the cutting tool operates along the XYZ plane to trim away material. This is suitable for parts that don`t require a lot of depth and detailing. 3 axis machining is most commonly used to produce mechanical components and is best suited for:
Automatic/interactive operation
Milling slots
Drilling holes
Cutting sharp edges
CNC machining can be broken down into several common types: 3-Axis, 4-Axis, 5-Axis, Turning, and Electrical Discharge Machining (EDM). Although other CNC machining processes exist, such as screw machining, the focus of this CNC machining guide is on the former list.
CNC machining is a broad category for a range of processes. Computer Numerical Control (CNC) is the automated control of machining tools by means of a computer. A CNC machine transforms a piece of material according to instructions from a computer programmed to precise specifications. Although there are manual operated devices for machining, CNC machining provides accuracy and repeatability for the desired result, at a desired price.
