The engine in the production of rotary vane vacuum pumps _

incinerator in the sediment of engine is very serious, but it's not a independent appraisal target, usually used with IVD. In contrast to the nozzle and the difference of intake valve deposits, use cleaner, only increased the sediment in the incinerator room, and then reduce the incinerator room space. Incinerator, therefore, the increment of sediment size control it only once. Here provides the rotary-vane vacuum pump are applied in the incinerator chamber vacuum solutions.

rotary-vane vacuum pump are used as the backing pump, in keeping with the vacuum pump pressure before the level before the pressure below the critical level. It is associated with pumping time and economic effect, so its function is still large. Therefore, when choosing rotary-vane vacuum pump are need to pay attention to what principle?

vacuum also is closely connected with the former stage pump unit. If there is no backing pump, vacuum unit will not be able to start, because it requires a lot of pressure to launch, but not to start motor power, otherwise it will damage the vacuum pump, environment, use different types of pump need to configure the backing pump is also different. Water ring vacuum pump used in the state of a large number of condensable gas, corrosive gas also need to use the water ring vacuum pump, while allowing water to reduce the concentration of the corrosive gas, and the water pump is a pump. In the first category, there are other vacuum pump, such as reciprocating. You need to the speed of the pump and vacuum degree are different. Use the preamplifier of pump is different.

incinerator chamber of adiabatic preparing, at one end of the blasting machine shell has a Φ 200 mm? Φ 300 mm small openings, the other end is oval, therefore cannot be accomplished through the use of the insulation of the incinerator. Conventional patch. Rotary vane vacuum pump heat insulation molding. The initiator of the shell of the insulating layer is the main reason of the stripping gas residue between the shell and the insulating layer and insulating layer and the insulating layer. The initiator of the shell with internal insulation components placed in a vacuum environment, and then perform a series of technique operation, so that the insulation preforming billet in the vacuum state, vacuum up to 50 Pa, and insulation processing. The airbag pressure conditions. The layer of repression and thermal bond to the initiator of shell. Vacuum insulation after curing, the initiator of shell ultrasonic checks showed no stripping phenomenon. Rotary-vane vacuum pump are adiabatic forming has been successfully applied to certain types, thus improving the power of this type of internal insulation of solid rocket launchers and quality.

solid propellant was lit in the combustion chamber and combustion, chemical energy is converted into heat energy, to produce high temperature and high pressure combustion products. Combustion product flows through the nozzle, where inflation and accelerating, thermal energy into kinetic energy. From the nozzle discharge to produce thrust at a high speed. Can be seen from the above, the rotary vane vacuum pump application in the trigger device incinerators in eliminating the engine nozzle and inlet valve sediment aspect really has a good effect.

Over the years, has become very popular as more and more people are trying it out.
