Abstract

A movable air compressor for mine, traffic and building is composed of main unit, diesel engine (or motor), regulating system and air storage tank. Its advantages are simple structure, easy manufacture, low cost, small size, saving labour, flexible movement, high safety and reliability, and convenient maintenance.

Description

Movable air compressor

The utility model is the aerodynamic force driving arrangement that is used for mine, traffic, construction industry.

At present, the air compression driving device in domestic and international mine, traffic, the construction industry does not have desirable solution so far.The air compressor structure that manufactures and designs now is unreasonable, bulky, cost is higher, unstable properties, starting difficulty, move dumb, in addition part wear-resistant poor, automaticity is low, poor safety performance, mechanicalness noise are big, the user uses very inconvenient, and it is also relatively more difficult to change quick-wear part.Therefore develop a kind of new mobile type air compressor is new problem anxious to be solved both at home and abroad always.

The purpose of this utility model be exactly for provide the simple and science of a kind of structural design, manufacturing process easily and rationally, volume is little, in light weight, cost is low, performance is better than now air compressor, it is flexible to move, change that easily damaged parts is easy, mechanicalness noise is little, safe and reliable, the user uses mobile air compressor easy to maintenance.

The purpose of this utility model is achieved in that whole device partly is made up of main frame, diesel engine (or motor), regulating system, gas holder etc., main frame and diesel engine (or motor) are installed in respectively on the two block plates on the gas holder forms one, movably travelling wheel is installed under the gas holder, main frame is connected with centrifugal clutch by the vee belt with diesel engine, and main frame, diesel engine (or motor) are equipped with vibration damper with the connection part of gas holder.Main frame is by bearing cap, bent axle, bearing, connecting rod, cylinder, piston, filter cleaner, air valve, cylinder head, fan pulley, bearing support, crankcase is formed, cylinder head is the isolated structure of suction and discharge heat, three cylinders are installed in the crankcase top with W shape, angle is 75 ° mutually, crankshaft-and-connecting-rod mechanism is installed in the crankcase with the double supporting structure pattern by two rolling bearings, bent axle is for singly turning the type structure, the connecting rod cross section is I-shaped, piston is a tubular, have three road annular grooves outside on the cylinder of garden, piston ring is housed respectively from top to bottom, twist type ring and scraper ring, respectively encircle opening during assembling and stagger 120 ° mutually, the top clearance of piston in cylinder is 0.5-0.8mm, and this gap is to adjust with the pad of cylinder below flanged surface and crankcase joint, and the outer garden of cylinder face is cast with radiating fin, air valve is the suction and discharge combination brake switch and proporting, on air valve, have the suction and discharge passage, king's font exhaust valve plate and lift limiter are housed above air valve, the ligulate suction valve chip is housed below air valve.Main points of the present utility model are its structural type and drive regulating system.Its working principle and operating method are: during the hand starting diesel engine, clutch disconnects the transmission of diesel engine and main frame, after the diesel engine starting rotating speed reaches certain value, clutch meshes automatically, drive bent axle by vee belt and fan pulley, bent axle is produced to rotatablely move, it is reciprocating in cylinder to drive piston by crankshaft rotating by connecting rod, when piston during to the axle lateral movement, ambient air passes through filter cleaner, the air-breathing valve chamber of cylinder head is inhaled into cylinder, because cylinder head adopts hot isolated structure, suck gas and not influenced by exhaust gas heat, make compressor have advantage energy-conservation and that the life-span is long.When piston to lid during lateral movement, Aspirating valves cuts out, gas is compressed in the cylinder, when gas in the jar reached rated working pressure, outlet valve was opened, pressurized gas enters gas holder through exhaust valve chamber, the gas exhaust piping of cylinder head, for use.Regulating system is housed on the gas holder, when the jar internal pressure surpasses rated working pressure 5 percent, it makes the gas holder inlet close, and the main exhaust mouth is directly connected with extraneous, makes compressor no-load running, to reach purpose of energy saving, safety valve also is housed on the gas holder, in case jar internal pressure surpasses at 10% o'clock of rated working pressure, safety valve is opened automatically, give off a jar interior unnecessary gas, to guarantee the machine safe operation.

The utility model compared with prior art, have that simple in structure, easy to manufacture, cheap, the little dexterity of body, starting are laborsaving, good stability, safe and reliable, move flexibly, use the maintain and replace easily damaged parts convenient, advantages such as fault-free sport life span length, low-loss and energy-saving will be widely used in mine, traffic, the construction industry.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
