Our country terrestrial area is vast, mineral products is resourceful. Each cities are in ceaseless construction, the demand to steel and iron is very big. And the exploitation process of mineral products resource is very hard actually, basically every kinds of ore laps in rock, bury greatly in the mountain range under. The development of contemporary and mechanical equipment, made very large contribution for exploitation of mineral products resource, this includes pneumatics plane among them. Next, small arrange those issues that will tell pneumatics machine and mineral products exploitation. The value of mineral products resource is tremendous, in the exploitation process of mine, can encounter a lot of relatively complex construction problems. For instance, the interior of the mountain range is to do not have air, devoid airy is among them after mine hole is opened, be about to use pneumatics machine at this moment. It is the energy-saving problem on mine moreover, if use electric energy to mean the position to be able to not move, this is existing the limitative problem on the space, machine of mobile screw pneumatics uses diesel oil in this kind of setting very appropriate. Machine of pneumatics of derv shift screw is a kind of pneumatics machine, it is kinetic energy with derv, not the limitation of benefit from report, as it happens can satisfy the mobile requirement of equipment. Need to be used where, very convenient. In the process of mining, can use device of a lot of pneumatic, machine of pneumatics of derv shift screw can provide air kinetic energy. In abstruse mine hole, often can appear the problem with inadequate air, at that time, machine of pneumatics of derv shift screw can compress the air outside to undertake filtering, to clean air is offerred inside the hole. What machine of pneumatics of derv shift screw uses is lead plane of new-style screw compressor, tooth form of use appropriative rotor, can bring more superior performance for the machine. In the meantime, it has more solid axial and journal bearing, service life is longer. To get used to operating condition, added exceed big condenser and fan to be used medicinal powder hot, in order to get used to field and abominable work requirement. In using a process actually, the tolerance regulating unit of machine of pneumatics of derv shift screw can undertake self-correcting, quantity of the rotate speed of the inspiratory quantity that assures pneumatics opportunity and diesel engine, air feed, air consumption photograph matchs, use up the effect with be achieved better with less fuel as far as possible. Extract in mine about pneumatics machine medium main effect, small make up introduce here! Current, all sorts of type kind of pneumatics machine still are expanding in, with more accord with more complex and changeful construction environment and market demand. “The burrow that wear hill ” finish hard? Is that you still do not know screw pneumatics machine to become air the sources of energy? Decode pneumatics machine ” preexistence this life ” machine of pneumatics of derv shift screw, what characteristic is there? What construction to suit?
