Structure and Characteristics of Roots Screw Vacuum Pump Unit

Roots screw vacuum pump unit can be widely used in pharmaceutical, chemical, aerospace, electronics, solar energy, metallurgy, food and other industries, the unit is suitable for chemical and pharmaceutical industries, high vacuum distillation, vacuum evaporation, Dehydration and crystallization process; It can also be used in the vacuum impregnation and vacuum drying process of electric power industry, or the ideal vacuum equipment for vacuum coating, vacuum smelting, vacuum heat treatment, vacuum oil filtration, freeze-drying and aviation simulation. Then Roots screw vacuum pump unit structure is what? And what are the characteristics? Then introduced Roots screw vacuum pump unit structure and characteristics. Roots screw vacuum pump unit structure and characteristics of the screw vacuum pump unit is composed of ordinary roots pump and the middle of the pump, screw pump for the fore pump in series oil-free vacuum pump unit. Roots vacuum pump and screw vacuum pump working principle and structure similar to the Roots vacuum pump and screw vacuum pump unit has the advantages of screw vacuum pump at the same time through the series pumping speed Roots vacuum pump, doubled the pumping speed of the screw vacuum pump to raise the limit Vacuum degree, at the same time make exhaust system has better energy-saving effect. Roots screw unit high degree of vacuum, high vacuum pumping efficiency. Through the matching control system, the unit should be automatically Kai, stop, and with overload, over current, water and other automatic protection. The entire vacuum unit can be anti-corrosion treatment, so that it can be used to remove corrosive gases occasions. When the vacuum pumps of the units adopt vertical stacking or stepped structure, the unit area is small, and foreign matter is not easy to accumulate for each pump and the middle pipe. It has obvious advantages when pumping gas containing small amount of condensable gas or small amount of dust. According to the size of the pumping system, work pressure and other factors reasonably configure the vacuum unit, vacuum pump unit pumping ratio (pumping ratio) can be selected between 1: 2 ~ 1: 8, the ratio will increase the pump pumping Reduced gas efficiency, reduced working pressure range, slow start, extended pre-pumping time.

Solid-phase synthesis, as the main process in the production of Bio-pharmaceuticals, is widely used for the synthesis of peptides, deoxyribonucleic acid (DNA) and so on. The synthesis method is to bound the functional group such as hydroxymethyl on a bead, which primiarly is polystyrene microsphere with low crosslink.

Solid Phase Synthesis Resin based on monodisperse beads is able to keep the unformity of the modified functional group, enhance the quality of the target products, reduce the occurance of drug allergy and lower the production cost.
