Separation technology is an extremely widely used technology, applicable to pharmaceutical, chemical, metallurgy, textile, environmental protection, food, military and other industries, it is to promote liquid-solid, liquid-liquid or liquid-solid suspension by centrifugal force Liquid or emulsion according to the characteristics of physical properties, different separation requirements to achieve a different separation of a device, due to its simple structure, high efficiency, pure physical separation process, can fully guarantee the characteristics of the separation of materials. Therefore, the market for centrifuges is extremely broad.
As we all know, the harm of corrosion is extremely large. There are many examples in the world to illustrate that the centrifuge is a high-speed rotating device. Its safety requirements are as important as the pressure vessels. Most of the centrifuge manufacturers are designing, selecting and In the application, more consideration was given to the effect of uniform corrosion on the strength parts, and the structural design, processing technology, and other adaptations to the corrosive environment were neglected, resulting in some serious consequences. Not only does the part have a tendency to corrode, it pollutes the material being separated, and even more serious causes the machine to die.
First, the centrifuge environment
Centrifuges are divided into different types of equipment by function and structure, but they all have common features:
1, drum for high-speed rotating parts;
2, the main body of the drum constitutes a separate space;
3, drum was shaped structure;
4. There are some other connectors or accessories in the drum.
These characteristics of the drum indicate that the core part of the centrifuge is a stress piece. Its irregular geometry leads to the distribution of stress distribution of parts and the cooperation of multiple parts, which in turn makes it possible to form a pair of electric couples. This is something worth noting.
Second, the possible corrosion phenomenon
Corrosion morphology is mainly divided into two categories: uniform corrosion and local corrosion. The former is easy to find because of apparent phenomena, and it is clearly stated in most manual data. It will not be elaborated here. Only the latter is discussed.
Corrosion occurs only partially, is a very serious and harmful damage, such as pitting, crevice corrosion, intergranular corrosion, stress corrosion, wear and corrosion, etc. In the centrifuge, local corrosion is widespread, Emphasis is placed on analyzing the mechanism of its formation, taking measures and overcoming them.
1.Our company produce high quality products for small and medium plate, plate type, shell type, automobile connecting rod and the hydraulic valve and mold class of complex parts .realized the high precision, high efficiency,automatic , flexible, low cost and many other features.
2. features of machine
1)Basic part of the machine adopts special casting, useing of Vertical Machining Center lathe bed and a sliding seat , so it has high rigidity structure. height from worktable to ground is also greatly reduced, it is more easy to operate and loading and unloading workpiece for workers
2)The guide rail and the work table are quenching and grinding, plastic pate matched with the guide rail lubrication, automatic Intermittent lubrication , feeding smoothly without crawling, keeping good accuracy.
3)Machine tool with x/ yaxes both are the ball screw drive, connection mode for motor and screw is direct connection
4)The machine has the strong cutting, high flow rate of cooling, the width of the swarf discharging slot
5)Can be equipped with guangzhou cnc system .model 980MD . Three axis are servo motor control mode.
Spindle box is full gear transmission structure, the max torque of the spindle is 350NM, spindle box can move up and down by manual.
