Description
Technical field
The present invention relates to a kind of accurate filling apparatus of high viscosity fluid constant temperature and pressure, belong to filled fluid technical field, have
Body is related to the filling apparatus that miniature composite solid pushes away motor charge batch production.
Background technology
It is one of power set main in China's national defense cause and aerospace industry that composite solid, which pushes away engine, and it is used
Fuel be solid propellant.Composite solid, which pushes away engine as carriage by air carrier, needs extremely accurate kinetic parameter, in the inner
The combustion stability and coherence request of portion's propellant are high.Because composite solid pushes away motor body physical dimension and solid propellant propulsion
The diversity of agent prescription, for the engine of different structure function, need to use different charging means.Current composite solid, which is pushed away, to be started
The most common charging means of machine are spray cast under vacuum, i.e., motor body is placed in sealed vacuum chamber, medicine slurry exists
Uniformly freely it is dropped in the presence of atmospheric pressure by flow control valve in housing.
Miniature composite solid pushes away motor body external diameter and is generally 20mm to 50mm, and explosive payload is 10g to 100g.It is miniature compound
Admittedly push away and use ultra high burning rate propellant engine more, because the propellant has high concentration, low ignition point, high friction sensitivity, Gao Ran
Speed and containing can it is high the features such as, powder charge production exist higher security risk.According to the charging means of vacuum pouring, there is work
Difficult design, explosive payload control difficulty are filled, frequent disassembling fixture and cleaning difficulty problem is needed.And the powder charge side loaded by hand
Then there is the risky operation of frequently shovel medicine in formula, high viscosity medicine slurry causes powder charge speed slow, the shortcomings of doing over again time-consuming.
In summary, the features such as physical dimension that pushes away engine due to miniature composite solid is small, explosive payload is few and dangerous big,
Vacuum pouring mode and manual filling mode are difficult to safety, high-volume and the completion of low cost its powder charge pouring technology.Therefore
The characteristics of pushing away motor charge for miniature composite solid, designs a kind of simple and safe filling apparatus and can solve the problem that above mentioned problem.
