Construction and application of vacuum furnace


structure
The vacuum furnace is generally composed of a main engine, a furnace, an electrothermal device, a sealed furnace shell, a vacuum system, a power supply system, a temperature control system and an outside conveyor. The sealed shell is welded with carbon steel or stainless steel, and the joint surface of the detachable part is sealed by vacuum sealing material. In order to prevent the deformation of the shell after heating and the deterioration of the sealing material, the furnace shell is usually cooled by water cooling or air cooling. The furnace is located in the sealed furnace shell. According to the use of the furnace, the furnace is equipped with different types of heating elements, such as resistance, induction coil, electrode and electron gun. The vacuum furnace for smelting metals is equipped with a crucible, and some are equipped with automatic pouring devices and manipulators for loading and unloading materials. The vacuum system is mainly composed of vacuum pump, vacuum valve and vacuum gauge.
application
Vacuum furnace is a special space in the furnace chamber using vacuum system (by vacuum pumps, vacuum measuring devices, vacuum valves and other components assembled carefully) to discharge some of the material inside the furnace chamber, so that the pressure in the furnace chamber is less than a standard atmospheric pressure, the space in the furnace chamber to achieve a vacuum state. What is the application of vacuum furnace in heat treatment?
Vacuum furnace can not only be used for quenching, tempering, annealing and normalizing of common workpieces, but also for chemical heat treatment such as vacuum carburizing (including vacuum carbonitriding), vacuum ion carburizing and glow plasma nitriding. It can also be used for sintering, brazing and vacuum coating of metals. It has the advantages of clean and bright surface, less consumption of gas and gas source.

Reasons and Solutions for Fragile Belt of Roots Blower

图片
1. Reasons for easily broken belt of Roots blower: 1. First of all, consider the high speed and high temperature of Roots blower. 2. The distance between the head and motor of Roots blower is too large and the belt is tight. 3. The belt does not match the V groove of the pulley, so it can not withstand the load fracture after wearing. 4. Active pulley and driven pulley are not parallel, resulting in serious friction between belt and groove on one side, and can not bear load fracture after wear. 5. Heavy load, long-term overload operation of belt is easy to break. 6. Roots fan nose and motor pulley are not concentric, different axes. 7. Belt quality problems. 2. Measures to prevent the belt of Roots blower from breaking. 1. Roots blower must start without load before running. After starting, it should be loaded. After running, it can generally avoid triangular belt breaking. 2. The pulley between the motor and the fan should be parallel, which is a key point. If not para
