Abstract
The invention relates to a diversion cover for a semi-closed screw rod type refrigerating compressor, which comprises an air suction inlet, an air admitting filter, a motor casing wall, a flow channel at the back of a motor, a motor coil at the air suction side, a rotating part of the motor and a motor coil; the diversion cover for the semi-closed screw rod type refrigerating compressor also comprises a diversion cover; the diversion cover is arranged between the motor coil at the air suction side and the rotating part of the motor and fixed with a casing at the outer side of the rotating part of the motor; the diversion cover comprises a housing washer flat plate and a inner circle guiding blade; the housing washer flat plate comprises small holes fixed with the casing at the outer side; the inner circle guiding blade is composed of a plurality of blades which are routed up and form a certain angle with the housing washer flat plate; the position of the inner circle guiding blade is the outlet position of the flow channel at the back of the motor. The diversion cover for the semi-closed screw type refrigerating compressor has the advantages that the refrigerating agent entering into the compressor is operated along the designed flow channel, and the motor is sufficiently cooled; the motor stator can also be compressed through utilizing the diversion cover to perform the fixing function.
Description
Technical field
The present invention relates to a kind of semi-closed screw type refrigerating compressor, relate in particular to the structure between a kind of motor transfer part and the suction side motor coil.
Background technique
As everyone knows, when compressor operating, motor can send a large amount of heats, if these heats can't in time be pulled away, will cause the motor operating conditions abominable, even burn motor.
As seen from Figure 1, in compressor, owing to after the cryogenic gaseous refrigeration agent enters compressor from intakeport 1, directly motor is cooled off, can effectively take away motor part heat, but along with going deep into of refrigerant gas, refrigerant temperature raises gradually, reduces gradually with the heat transfer temperature difference of motor, and the cooling effect of motor is also weakened gradually, cause the temperature of motor inboard than outside height a lot, so the phenomenon that electrical machine insulation lost efficacy, burns takes place easily in that motor is inboard.Among the figure: air intake filter 2, motor shell wall 3, motor back runner 4, suction side motor coil 6, motor transfer part 7, motor coil 8.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of semi-closed screw type refrigerating compressor air guide sleeve, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: intakeport, air intake filter, motor shell wall, motor back runner, suction side motor coil, motor transfer part, motor coil; Also comprise an air guide sleeve; Described air guide sleeve is fixed between suction side motor coil and motor transfer part and with the outside casing of motor transfer part; Described air guide sleeve comprises: the dull and stereotyped and inner ring guide vane in outer ring; Described outer ring flat board comprises and the fixing aperture of outside casing; That described inner ring guide vane is upwards routed up by several, form with the dull and stereotyped angled blade in outer ring; Described inner ring guide vane position all is the exit position of motor back runner.
Compared with prior art, the invention has the beneficial effects as follows: make the refrigeration agent that enters compressor along designed runner operation, fully motor is cooled off; But also can utilize air guide sleeve clamping motor stator, play fixation.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
By Fig. 2, Fig. 3 A, Fig. 3 B as seen: the present invention includes: intakeport 1, air intake filter 2, motor shell wall 3, motor back runner 4, suction side motor coil 6, motor transfer part 7, motor coil 8; Also comprise an air guide sleeve 5; Described air guide sleeve 5 is fixed between suction side motor coil 6 and motor transfer part 7 and with the outside casing of motor transfer part 7; Described air guide sleeve 5 comprises: outer ring dull and stereotyped 51 and inner ring guide vane 52; Described outer ring flat board 51 comprises and the fixing aperture 511 of outside casing; Described inner ring guide vane is 52 that upwards routed up by several, form with the dull and stereotyped 51 angled blades in outer ring; Described inner ring guide vane 52 positions all are the exit positions of motor back runner 4;
Described inner ring guide vane 52 is angled with outer ring dull and stereotyped 51; Angle is between 0 °～90 °.
Working principle of the present invention is: the low-temperature low-pressure refrigerant of coming from vaporizer enters compressor vertically by intakeport, filter by air intake filter then, refrigeration agent after the filtration is the flow direction motor shell wall radially, realize the cooling of motor coil here, then continue to the compressor internal flow along motor back runner, realize the cooling of motor back iron core here, after flow out at the motor back, refrigeration agent is because the cause of heat absorption, temperature rises to some extent, cooling effect descends, and utilizes this moment air guide sleeve that refrigerant flow direction is changed, along the predetermined angle outflow of its guide vane, direct flow direction motor suction side coil, owing to the cooling of a large amount of refrigeration agents, remedied the deficiency of cooling effect, realized that the suction side coil effectively cools off.In addition,, increased its pressure drop, the refrigeration agent in the runner of runner motor back is cooled off uniformly because air guide sleeve changes refrigerant flow direction, can be in the outside phenomenon that produces local dewfall of motor casing.Carry out cooled refrigeration agent and continue to flow to compressor inside, enter the compressor air suction chamber, entered twin-screw compression back then and discharge compressor, enter system.
Air guide sleeve among the present invention is formed with the inner ring guide vane by the outer ring is dull and stereotyped, uniform several apertures on the flat board of outer ring wherein, these apertures can cooperate with the lug on the motor casing, mode with bolton is fixed on the motor casing then, while clamping motor stator, the axially locating of realization motor stator; The inner ring guide vane of air guide sleeve is made up of several blades of upwards routing up, these blades and outer ring flat board are angled, the position of each blade all is the exit position of runner, utilize these guide vanes can be effectively the refrigeration agent of compressor inside to be carried out water conservancy diversion, make the abundant cooling suction side motor coil of refrigeration agent, thereby effectively prevented the inboard high temperature of motor to jump machine, faults such as burn-down of electric motor.
