Description
Technical Field
The utility model relates to a relevant technical field of charge pump, concretely relates to low temperature bucket bag pump separates temperature structure.
Background
The canned motor pump has no leakage, totally enclosed structure, need not external lubrication, compact structure, advantages such as motor and coaxial an organic whole of pump, along with the improvement of country to the ring standard requirement, canned motor is more obvious in the environmental protection effect, and special operating mode improves barrel bag pump demand step by step, as shown in figure 1, ordinary barrel bag pump structure does, directly puts into the bucket with the pump in, and the medium gets into through impeller to pump body export through pump body entry, carries away through pump outlet pipeline. In the process, the surface of the motor emits heat and is taken away by the medium in the barrel, but aiming at the special easily vaporized medium, the common barrel bag pump structure has the problem that the medium in the barrel is vaporized due to the surface heat emission of the motor, if the medium in the barrel is vaporized, gas enters the pump along with liquid flow, so that the pump is in failure, and the medium loss is increased.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the above not enough problem, provide a low temperature bucket bag pump separates temperature structure.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: low temperature bucket bag pump separates temperature structure, including charge pump, bucket, the charge pump is installed in the bucket, the charge pump is including the pump body, space stator, motor, the export pipeline that connect gradually, be provided with the impeller between the pump chamber of the pump body and the space stator, the impeller suit is in the pivot of motor, motor surface cover is equipped with separates the temperature sleeve, forms motor surface cavity between the two, separate temperature sleeve one end and install on the space stator, the other end is installed on the bearing frame of motor, the intercommunicating pore has been seted up on the bearing frame, the pump chamber one end and the bucket inner chamber intercommunication of the pump body, the other end loops through impeller, space stator, motor surface cavity, intercommunicating pore and export pipeline intercommunication.
The pump body is installed on the space guide vane through fastening bolts, and the outlet pipeline is installed on a bearing seat of the motor through fastening bolts.
One end of the heat insulation sleeve is sleeved in the space guide vane, a sealing ring is installed between the heat insulation sleeve and the space guide vane, and the other end of the heat insulation sleeve is installed on a bearing seat of the motor through a fastening bolt.
The utility model is characterized in that: the introduction of the space guide vane changes the sequence of the flowing direction of the medium, the influence of the heat dissipation of the motor on the medium in the barrel is isolated through the cavity on the surface of the motor, the vaporization of the medium in the barrel caused by the absorption of the heat dissipated from the surface of the motor is avoided, the possibility of fault occurrence is reduced, and meanwhile, the effect of improving the efficiency is achieved.
Drawings
Fig. 1 is a schematic structural view of a conventional cryogenic sleeve.
Fig. 2 is a schematic structural diagram of the present invention.
Wherein: 1. the device comprises a barrel 2, an electric pump 21, a pump body 211, a pump cavity 22, an impeller 23, a space guide vane 24, a motor 241, a rotating shaft 242, a bearing seat 243, a communication hole 25, an outlet pipeline 26, a heat insulation sleeve 261 and a motor surface cavity.
Detailed Description
As shown in fig. 2, the utility model relates to a low temperature bucket bag pump separates temperature structure, including charge pump 2, bucket 1, charge pump 2 is installed in bucket 1, charge pump 2 is including the pump body 21, space stator 23, motor 24, the outlet pipe way 25 that connect gradually, the pump body 21 passes through fastening bolt and installs on space stator 23, outlet pipe way 25 passes through fastening bolt and installs on motor 24's bearing frame 242, be provided with impeller 22 between the pump chamber 211 of the pump body 21 and the space stator 23, the impeller 22 suit is on motor 24's pivot 241, motor 24 outer surface cover is equipped with separates temperature sleeve 26, forms motor surface cavity 261 between the two, separate temperature sleeve 26 one end suit in space stator 23, install the sealing washer between the two, seal through the sealing washer, it installs on motor 24's bearing frame 243 through fastening bolt to separate the temperature sleeve 26 other end, the connection design of separating temperature sleeve 26 is convenient for its dismantlement, the intercommunicating hole 243 has been seted up on the bearing frame 243, the pump chamber 211 one end and the bucket 1 inner chamber intercommunication of 21, the other end loops through impeller 22, space stator 23, motor surface 261, motor surface 243, the pump body and outlet pipe way 25 intercommunication.
The utility model discloses introduce original pump body structure of space stator 23 replacement, change medium flow direction order, the medium flow direction is got into by the pump chamber 211 one end of the pump body 21, through impeller 22 to space stator 23, rethread space stator 23 gets into motor surface cavity 261, the medium is gathered into to outlet pipe 25 through connecting hole 243 after motor surface cavity 261 takes away the heat that motor 24 gived off and is derived, because the medium on motor 24 surface of flowing through pressurizes through impeller 22, so this department medium has little temperature rise also difficult vaporization, motor surface cavity 261 has completely cut off the influence of motor 24 heat dissipation to medium in the bucket 1, the medium leads to the emergence of vaporization because of the heat that absorbs motor 24 surface givedown in having avoided bucket 1, reduce the trouble and take place the possibility, play the effect that improves the performance simultaneously.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered as the technical scope of the present invention, and equivalent substitutions or changes according to the technical solution of the present invention and the inventive concept thereof, which are within the scope of the present invention.
