Quid est principium vacuum coating machina?

I. Vacuum Main Corpus - in magnitudine vacuum camera variatur secundum ad requiruntur processionaliter products. At present, the widely used diameters are 1, 3M, 0, 9M, 1, 5M, 1, 8M, etc. The cavity is composed of "Stainless steel" target=_blank>Stainless steel material, requirements are not rusty, solid, etc., each part of the vacuum chamber has a connection valve to connect each pump.

II. Auxilium aer extraction ratio: et exhauriunt ratio est momenti pars in vacuo systema de coating apparatus, quod est maxime composito ex mechanica pumps, Booster Pumps (maxime in mechanica soleatus), et purgantibus Pumps. Hoc exhaurit ratio est composito ex "Diffusio pump mechanica mentis radices pump cryogenic frigus captionem polycold." The exhaust process is: the mechanical pump pumps the vacuum chamber to a low vacuum state of less than 2, 0*10-2PA, which provides a prerequisite for the subsequent vacuuming of the diffusion pump, and then when the diffusion pump pumps the vacuum chamber, the mechanical pump cooperates The oil diffusion pumps are connected in series to complete the pumping action in this way.
Mechanica sentinam et vocavit tergum pump. Mechanica sentinam est late usus humilis vacuum sentinam. Non utitur oleum ponere ad signantes effectus et innititur in mechanica modi ad continue mutare volumine de suctu cavitatis in sentinam ad facere continens exantlaretur. Volume Gas intra continuum dilatavit obtinere vacuo.

Classification of mechanica pumps: Sunt multa genera mechanica pumps. Communiter adhibetur, quae sunt lapsus valvae type (hoc maxime in magna apparatu), piston reciproco genus, certum vane type et gyratorius vane type (hoc est currently in used, hic articuli maxime inducit) quatuor genera. Mechanica sentinam animi ad opus a atmosphaera. Et principalis parametri sunt ultima vacuo et elit rate. Hoc est momenti basis ad consilium et lectio mechanica sentinam. In uno-scaena sentinam potest sentinam in quo a atmosphaera ad ultimum vacuo ex I, 0 * 10-1pa et duo-scaena mechanica sentinam potest sentinam in quo a atmosphaera ad VI, VII * 10-2pa, aut etiam altior. Et elit rate refers ad volumen de Gas, qui potest esse per unitas tempus cum gyratorius vane sentinam currit ad rated celeritate. It can be calculated by the following formula: Sth=2nVs=2nfsL fs represents the cross-sectional area of ​​​​the cavity at the end of the suction, and L represents the void Cavity length, the coefficient indicates that the rotor has two exhaust processes per revolution, and Vs indicates that when the rotor is in a horizontal position, the suction ends, the volume in the cavity is the largest at this time, and the speed is n. Et exhaurit effectum mechanica sentinam quoque ad celeritatem motricium et emissiones ad balteum. Cum balteum motricium est relative solutam et celeritatem motricium est tardissimum, exhauriunt effectus mechanica sentinam erit et facti pejus, ita crebris sustentacionem non requiritur. Et signa effectus ex mechanica sentinam oleum etiam indiget ad sedatus frequenter. Si est parum oleum, et signing effectus non erit effectum. Et sentinam erit Leak Aeris, nimium oleum et angustos ad supplicium foraminis et non potest ad haurire et exhaurit. Et oleum gradu est 0 vel V cm infra lineam. Mechanica pumps saepe solebat sentinam sicco aer, sed non sentinam vapores cum excelsum oxygeni contentus, explosive et mordax vapores. Mechanica pumps sunt plerumque ad sentinam de permanens vapores, sed non sunt bonum in humorem. Effectus, ita non potest removere humorem. Pelagus partes gyratorius vane sentinam sunt stator, rotor, shrapnel, etc Rotor est intra stator sed habet axis axis ex stator, sicut duo inscribitur circulos. Sunt duo shrapnels in rotor socors, et vere est installed inter duo shrapnels. Ut shrapnel est arcte coniuncta interiore murum Stator.
