Description
Technical field
The utility model relates to a kind of direct-connected helical-lobe compressor, particularly relates to the motor cooling of this direct-connected helical-lobe compressor.
Background technology
The compressor efficiency that direct-connected helical-lobe compressor comparatively uses standard electromotor to drive is higher, and operating cost is lower.This is because motor transfer part is directly in male rotor, and eliminate motor shaft spring bearing and shaft coupling, the power consumption of this part is saved, and structure is also compacter.But due to influencing each other of compressor block and these two thermals source of motor, motor radiating deleterious.
Prior art mainly employ outside water jacket (or oil jacket) cooling and internally air-cooled two kinds of forms to improve motor radiating effect.
Outside water jacket (or oil jacket) type of cooling mainly overlaps water route (or oil circuit) runner outward at motor stator, is spread out of by coil heat by stator core.But this mode is due to motor internal non-moving air, between rotor and stator, air gap heat transfer efficiency extreme difference, usually can cause rotor high temperature, and therefore rotor burns or the lost of life.
Internally air-cooled form is then by utilizing axle head fan air-supply by motor breath, arranging gap etc. between stator and support as the direct cooling coil of air flue and iron core.This structure can be used as the finite gap of air flue due to motor internal, improved cooling limited efficiency, part is even without improvement, and employ the casing structure of IP23, can not apply very well in the environment of windy dirt (screw air compressor operational environment is generally being operated in simple and easy air compressor house or awning, many dust).
Summary of the invention
The utility model technical issues that need to address there is provided a kind of motor cooling of direct-connected helical-lobe compressor, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: motor housing, motor bonding part and motor transfer part; Described motor housing comprises: motor base and the electric motor end cap be fixed thereon; Described motor base comprises: afterbody end plate, motor housing, oil jacket, anterior end plate; Described afterbody end plate is used for fixed electrical machinery end cap; Described afterbody end plate passes through mode and the motor housing integrator of welding; Described anterior end plate is fixed on motor housing by welding manner, for connecting screw rod compressor body; Described oil jacket is integrally formed with motor housing by welding manner, and for providing fixing for motor bonding part and supporting, and the heat that motor bonding part produces is taken out of by the heat exchange of oil jacket; Described motor transfer part is provided with axle head fan.
Compared with prior art, the beneficial effects of the utility model are: machine operation temperature is obviously reduced, and electrical machinery life is extended, and motor radiating is even; And motor degree of protection reaches IP54, adapt to the environment of many dust completely; Heat transferring medium shares with compressor oil, and entire system is succinct.
Accompanying drawing explanation
Fig. 1 is the electric machine structure schematic diagram of the direct-connected helical-lobe compressor of the utility model.
Fig. 2 is the motor cold oil circulation process figure of the direct-connected helical-lobe compressor of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: motor housing 10, motor bonding part 20 and motor transfer part 30; Described motor housing 10 comprises: motor base and the electric motor end cap 101 be fixed thereon; Described motor base 102 comprises: afterbody end plate 1021, motor housing 1022, oil jacket 1023, anterior end plate 1024; Described afterbody end plate 1021 is for fixed electrical machinery end cap 101; Described afterbody end plate 1021 passes through mode and motor housing 1022 integrator of welding; Described anterior end plate 1024 is fixed on motor housing 1022, for connecting screw rod compressor body by welding manner; Described oil jacket 1023 is integrally formed with motor housing 1022 by welding manner, and for providing fixing for motor bonding part 20 and supporting, and the heat that motor bonding part 20 produces is taken out of by the heat exchange of oil jacket 1023; Described motor transfer part 30 is provided with axle head fan 301.
In the utility model, whole motor housing 10 forms an airtight inner space, makes the protection class of motor reach IP54.
Inner at electric machine casing in the utility model, motor bonding part 20 and oil jacket 1023 closely cooperate, and the heat that motor bonding part 20 produces is directly passed to oil jacket 1023 by the mode of heat exchange.Motor transfer part 30 directly contacts owing to not existing with oil jacket, so the caloric requirement that transfer part 30 produces first passes to inner air, again by transfer of air to oil jacket 1023, so arrange the air that axle head fan 301 drives inner space in end, utilize internal clearance formation air-flow as illustrated by the arrows in fig. 1, under airflow circulating effect, effectively can accelerate the exchange of the high temperature air near transfer part 30 and the Cryogenic air near oil jacket 1023, thus accelerate transfer part 30 heat transfer to oil jacket 1023, the heat obtained is passed to the cold oil (compressor oil) of its inside by oil jacket 1023, heat is taken out of motor.
The circulating path of cold oil as shown in Figure 2.The form that cold oil mixes with high-temperature oil gas is got rid of from compressor machine E-1, enter gs-oil separator E-2, and realize Oil-gas Separation, High-temperature cooling oil is under differential pressure action, flow out from gs-oil separator E-2, cool through oil cooler E-3, cooled lubricating oil flows through motor E-4 (motor oil jacket 1023), the heat that motor produces is taken away, then flows to compressor E-1.
Motor cooling is cooled reasonable combination with compressor by the utility model, the cooling effect of motor is all effectively improved from the reduction of working temperature or the uniformity coefficient that dispels the heat, and cooling system can not increase equipment because of the change of the motor type of cooling, entire system is succinct.Its practicality also shows that the shell of motor is hermetically-sealed construction, and safeguard structure grade reaches IP54, can be good at the operational environment adapting to the general many dust of air compressor, thus improves the adaptability of air compressor entirety.
