KX-P Type: It adopts the world-famous Germany Leybold vacuum pump as the vacuum drive and imports the very high vacuum special-used glass to produce elaborately; It has the airproof design which adopts the screw thread pushing type without oil and the very high vacuum ripple pipe joints with the international standardized swift discharge joint meet. The minityped adjusting cooper valve and theBOC Edwards vacuum importing press meter from England are used to control the charging quantity. It has a big cubage cylinder gas (cubage: 1.4 L, purity: 99.999%, compressive press: 100Mpa). The digital thermometer is used to monitor and measure the temperature and the finger-type vacuum instrument is used to do the vacuum direction, and the wind cold-type diffusion pump is used to improve the system vacuum degree and the pumping speed. (Pumping speed: 80L/S, Vacuum degree: 5*10-4Pa). Besides, it adopts the pipeline separation design method which improves the lifespan of the diffusion pump and also adopts double direction discharging method which improves the working efficiency.
