Compressor of air of frequency conversion screw, managing the sources of energy saves machine of systole of atmosphere of electric frequency conversion, first class can effect, machine of screw of general frequency conversion just holds the arrangement of a bosom through arranging electric machinery rotate speed, make the platoon bosom of air compressor and the bad news bosom that furnish with gas are accorded with. And the two-tier arrangement that machine of screw of VJ series frequency conversion can execute a bosom and exhaust pressure, each other independent platoon bosoms and discharge baric force arrange with of these two parameter rises, this disappear the other party is chief, extended child to apply a category. What series of true frequency conversion and machine of screw of general frequency conversion communicate is: Do not pass measure of a kind of arrangement, pass transducer establish will execute. Its biggest advantage is, what protect pressure of pipeline network stylistic rules and layout the can most lucidly is halcyon; Most accord with applying is to use bosom to change again and again place, reach change to exerting pressure relatively the decoration using gas of acumen. Suggest every 1500-2000 hour changes new strain core, core of engine oil filter changes at the same time when oil change. Should shorten when the environment is harsh change periodic. Forbidden use core of engine oil filter for long. Otherwise, because filter core jams badly, press difference to exceed the limit of by-pass valve, by-pass valve can be opened automatically. A large number of spoil and grain can enter screw lead plane directly, cause serious consequence. Atmosphere is to show gas issues refrigeration to be contained to place in standard atmosphere not saturated vapor becomes saturated vapor and the temperature of separate out. In pneumatics machine industry, it shows dry rate of gas. Between rotor of yin and yang and rotor and air cylinder and the between space that air cylinder builds have to the specific power consumption of screw pneumatics machine showing an effect. The treatment precision that raises rotor and surface are bright and clean spending is the significant step that reduces nose component gap. Compressing air is one kind is used at drive motivation and control gas a powerful person the gas of amiable crock. In debugging a process, ordinary tap water is full of inside compressor, next ceaseless condensation is dry, produce clean fresh water. Additional, the clean water that passes condensation still does not contain calcium to pledge, mineral water produces the order of different in a year season to also differ: Some season are produced two classes, some season work by turns production, all these metropolises cause the change that reduces air demand.
