Abstract
The utility model discloses a mechanical device, and particularly relates to a compressor provided with a dust cover and used for an engineering mechanical air conditioner. The compressor comprises a compressor body, a belt wheel and a sucker, wherein the outer end face of the sucker is provided with a protective cover, and the protective cover and the sucker are fixed through bolts. For achieving better effects, the gap between the sucker and the belt wheel is controlled between 0.3-0.5mm. The compressor has the advantages that the compressor is convenient to manufacture, low in cost and good in dustproof effect, and the service life of the compressor can be effectively prolonged. The compressor can be widely applied to manufacturers of engineering mechanical air conditioners.
Description
Technical field
The utility model relates to a kind of mechanical device, specifically refers to a kind of air-conditioner of engineering machinery compressor with dustproof construction.
Background technology
Idle call compressor is in air-conditioning refrigerant loop, to play compressible drive cold-producing medium.Work Zhong Fen evaporating area, loop and condensing zone, indoor set and off-premises station belong to respectively high pressure or low-pressure area.Compressor be generally contained in outdoor in, compressor extracts cold-producing medium after compressor, to deliver to that higher-pressure region is cooling condenses from low-pressure area, by fin, gives out heat energy in air, cold-producing medium is also from gaseous state liquefy, pressure rising.Cold-producing medium flows to low-pressure area from higher-pressure region again, through capillary, is ejected in evaporimeter, and pressure drop, liquid refrigerant becomes gaseous state immediately, by fin, absorbs heats a large amount of in air.Like this, machine is constantly worked, and just constantly the heat absorption of low-pressure area one end is dispersed in air to delivering to higher-pressure region in cold-producing medium again, plays the effect of climate comfort.Air-conditioning is when making refrigerating operaton, after the refrigerant gas of low-temp low-pressure is sucked by compressor, pressurization becomes the refrigerant gas of HTHP, the heat release in outdoor heat exchange gas of the refrigerant gas of HTHP becomes the liquid of middle temperature high pressure, the liquid of middle temperature high pressure becomes the liquid of low-temp low-pressure again after throttle part reducing pressure by regulating flow, the liquid refrigerant of low-temp low-pressure becomes the gas of low-temp low-pressure after absorbing heat in indoor exchanging air and evaporating, then enter compressor compresses, reciprocation cycle.Compressor is the heart of refrigeration system, is that air-conditioning, freezer, chemical refrigeration technique etc. operating mode all wants this important link of empty compressor to ensure!
Due to a large amount of development & construction of China, need a large amount of engineering machinery, and generally all operations in the wild of engineering machinery vehicle, working environment is poor, and air-conditioner of engineering machinery generally adopts used for automobile air conditioning compressor, front end clutch sucker generally adopts unenclosed construction, the working environment of engineering machinery is severe far beyond automobile, compressor is worked for a long time (such as coal yard in dirty environment, cement plant etc.), sucker open section easily enters grey laying dust, after while not working especially for a long time, do not start air-conditioning, compressor of air conditioner when work sucker can not be completely and belt pulley fit, friction produces high temperature, thereby cause clutch bearing and coil burnout.It is the technical problem that manufacturer makes great efforts to overcome that compressor for air-conditioner of engineering machinery is increased the service life, reduces spoilage always.
Utility model content
The utility model, for deficiency of the prior art, proposes a kind of method of mechanical air conditioner compressor for effective protection engineering.
The utility model is achieved by following technical proposals:
An air-conditioner of engineering machinery compressor for dust cover, comprises compressor, belt pulley, sucker, it is characterized in that there is a protective cover outer face of sucker, between protective cover and sucker, is bolted.As preferably, above-mentioned a kind of air-conditioner of engineering machinery with dust cover by the sucker in compressor and the clearance control between belt pulley between 0.3-0.5mm.Can better protect like this compressor to be subject to dust etc. to enter inside.This device is that employing is high temperature resistant, the protective cover of the radiator fan nylon PP Pipe Compound injection mo(u)lding of high tenacity, with the standard tooth of three M6, apart from bolt, be fixed on before compressor clutch on three screws on terminal sucker, for anti-bolt gets loose, need on bolt, coat thread locking glue.Protective cover has covered the open section of sucker front end, and dust can not be entered wherein, has effectively protected compressor.
Beneficial effect: the utility model is easy to make, with low cost, and also good dustproof effect, the service life that can effectively improve compressor.

The specific embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is illustrated:
Embodiment 1
Structure shown in 1, makes an air-conditioner of engineering machinery compressor with dust cover with reference to the accompanying drawings, comprises compressor 1, belt pulley 2, sucker 3, and wherein there is a protective cover 4 outer face of sucker 3, fixing by bolt 5 between protective cover 4 and sucker 3; Wherein the clearance control of 2 of sucker 3 and belt pulleys is between 0.3-0.5mm.Can better protect like this compressor to be subject to dust etc. to enter inside.The present embodiment is that employing is high temperature resistant, the protective cover 4 of the radiator fan nylon PP Pipe Compound injection mo(u)lding of high tenacity, with the standard tooth of three M6, apart from bolt 5, be fixed on before compressor clutch on three screws on terminal sucker 3, for anti-bolt 5 gets loose, need on bolt, coat thread locking glue.Protective cover 4 has covered the open section of sucker 3 front ends, and dust can not be entered wherein, has effectively protected compressor 1.
Claims (2)
