OIL REFINING MACHINE observer called the first angle projection method

OIL REFINING MACHINE observer called the first angle projection method. Projection plane in between the machine and the observer is called the third angle projection method. Both projection methods are equally well expressed in the shape of the part. China's Oil refining machine national standard provides for the first angle projection method.

The Oil refining machine cross-sectional view is a schematic view in which a part is cut away from the observer and the cut surface, and the remaining part is projected onto the projection surface to obtain a pattern. Section view is mainly used to express the internal structure of parts. The cross-section diagram only depicts the cross-section pattern. A sectional view is often used to express the cross-sectional shape of a rod-like structure.

For the Oil refining machine drawing of some of the more complex structure, in order to improve the efficiency of drawing allows to simplify it after drawing, simplified painting is called simplified painting. Mechanical drawing standards for which the threads, gears, splines and springs and other structures or parts of the painting system has an independent standard.

Oil refining machine Drawing is in accordance with the structural shape and size of the parts in accordance with the appropriate scale.

At the beginning of the 20th century, the mechanical structure of the drawing machine, improve the efficiency of drawing. In the second half of the twentieth century, a computer drawing was made, and the computer program was inputted into the electronic computer. The computer then converted it into graphic information to the plotter to draw the pattern, or sent to the automatic machine controlled by computer.

Oil refining machine Patterns generally need to be portrayed as a transparent base map, a blueprint with a transparent base map or ammonia smoked purple map. In the middle of the 20th century, there was an electrostatic copier, which replicates the original pattern directly and enlarges or reduces the figure. With this Oil refining machine new technology can save the tracing process.

Oil refining machine Mechanical seals, also known as face seals, are used primarily for sealing seals on rotating shafts of pumps, compressors, hydraulic drives and other similar equipment. Mechanical seal consists of a pair and a number of pairs of dynamic ring and static ring composed of the plane friction pair of sealing device.

The Oil refining machine mechanical seal is constituted by at least one pair of end faces perpendicular to the axis of rotation which are formed by the fluid pressure and the force of the compensating mechanism (or magnetic force) and the auxiliary seal cooperating to prevent the fluid from leaking. Compensating ring auxiliary seal for the metal bellows called bellows mechanical seal.

Oil refining machine composition

Mainly have the following four types of components:

1, the main Oil refining machine seal: the dynamic ring and static ring;

2, auxiliary Oil refining machine seals: seals;

3, Oil refining machine compression parts: spring, push the ring;

4, Oil refining machine transmission parts: elastic seat and keys or fixed screw.
