Abstract
The invention provides an integrated fully-sealed type refrigeration gear pump. The integrated fully-sealed type refrigeration gear pump provided by the invention adopts the following scheme: the integrated fully-sealed type refrigeration gear pump comprises a shell, a driving gear, a driven gear, a motor stator, a motor rotor and a shaft, wherein the driving gear, the driven gear, the motor stator, the motor rotor and the shaft are arranged in the shell; a fluid suction opening in the shell is connected with a fluid suction cavity and a fluid discharge opening in the shell is connected with a fluid discharge cavity; the motor rotor and the driving gear inside the shell are respectively arranged on the shaft and simultaneously operate; and all bearings inside the shell have no need of adding oil products for lubrication, namely a liquid refrigerant can be used for lubrication, so that the refrigeration effect is prevented from being influenced by that lubrication oil enters a refrigeration system. The integrated fully-sealed type refrigeration gear pump is free from leakage, light in weight, free from oil seal and capable of permanently solving the leakage problem and protecting the environment, and further can be used for power equipment of the refrigeration system or refrigerant transmission of a refrigerant factory; and proved by the detection, the integrated fully-sealed type refrigeration gear pump can be used in winter, and the energy conversation effect is up to 80%.
Description
Technical field
The present invention relates to a kind of integrated whole-closed type refrigeration gear pump, specifically be involved under winter condition the refrigeration system power equipment or provide power at factory's transmission refrigeration agent of producing refrigeration agent.
Technical background
in refrigeration system, generally by compressor, condenser, the refrigeration cycle that expansion valve and vaporizer form, and the energy consumption of compressor amount accounts for more than 60% of whole refrigeration system energy consumption, for some special dimensions, move due to 24 hours as communication operator server, server produces amount of heat, excess Temperature can cause server to damage, although in the winter time, the machine room heat load is little, but also need refrigeration to make within server remains on normal temperature, open just seem unusual power consumption of compressor under this operating mode, so use under a kind of new power equipment replaces compressor in the winter time and heat load is little operating mode in the urgent need to seeking.
When refrigeration agent production unit refrigerant conveying, very serious leakage problem is arranged between the pump housing, cause environmental pollution, be secondly when carrying pure refrigeration agent bearing without life problems under oil condition.
In prior art, the pump in refrigeration system or refrigeration agent factory is divided into two kinds of pumps, and a kind of is by the pump housing, and the pump that three kinds of relatively independent parts of shaft joint and motor form, the major defect of this pump are that easily leak at the shaft seal place of the pump housing, thereby causes the pollution of environment; Another kind is the magnetic shield pump, the shielding pump structure is each cover made with particulate metal material of stator and rotor part with motor, with their each selfsealings, thereby prevent the leakage of fed sheet of a media, but this type of pump manufacturing process is complicated, price is high, and time length also can cause the part leakage phenomenon.
Summary of the invention
Purpose of the present invention is exactly for the existing deficiency of prior art, and a kind of novel structure that provides, without leaking and a kind of integrated whole-closed type refrigeration gear pump of power can being provided to contrary Carnot's cycle and refrigerant conveying.
the present invention is achieved by the following technical measures, mainly comprise the motor stator in housing and housing, rotor, driving gear, driven gear and axle, there is liquid sucting port to connect imbibition chamber and liquid port connected drainage chamber on housing, it is an integral body that rotor in housing and driving gear are separately positioned on axle, and synchronous operation, the integrated totally-enclosed design of housing, be provided with bearing between driving gear and rotor, be provided with bearing in the driving gear side, bearing and bearing are separately positioned on axle, driving gear, driven gear, rotor and axle are to arrange with one heart, driving gear is arranged at driven gear inside, and driven gear is set for the eccentric.
Compared with prior art, the present invention has following advantage:
1, because this gear pump is sealed in motor stator, rotor, driving gear, driven gear and axle in a whole container fully, thereby solved the leakage problem at the place of shaft seal between the pump housing.
2, because whole sealed type housing has been full of refrigeration agent, play lubrication for the moving element that is arranged in housing, the refrigeration oil or other lubricant oil that have solved in order to play the lubrication interpolation partly enter into systemic circulation, affect system effect.
3, the low-temperature refrigerant liquid motor section of directly flowing through, the heat that the decrease machine operation produces, thus guaranteed the reliability of motor and improved working life.
This shows, the present invention compared with prior art has outstanding substantive distinguishing features and significant progressive, and its implementation result is also apparent.

Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, this programme is illustrated.
as can be seen from Figure 1, a kind of integrated whole-closed type refrigeration gear pump of this programme, mainly comprise the motor stator (2) in housing (1) and housing (1), rotor (3), driving gear (14), driven gear (13) and axle (6), there is liquid sucting port (12) to connect imbibition chamber and liquid port (4) connected drainage chamber on housing (1), it is an integral body that rotor (3) in housing (1) and driving gear (14) are separately positioned on axle (6), and synchronous operation, the integrated totally-enclosed design of housing (1), frame (7) is arranged on housing (1) internal surface by interference fit, motor stator (2), bearing (5) and the pump housing (8) are arranged on frame (7), bearing (5) is arranged between rotor (3) and driving gear (14), protecgulum (9) is arranged at the pump housing (8) side, bearing support (11) is arranged at protecgulum (9) side, bearing (10) is arranged on bearing support (11), bearing (10) is connected to axle (6) one ends.
as can be seen from Figure 2, a kind of integrated whole-closed type refrigeration gear pump of this programme, this axle (6) is arranged on driving gear (14) inside, and axle (6) and driving gear (13) are concentric, driving gear (14) is arranged on driven gear (13) inside, driven gear (13) is eccentric with respect to axle (6) and driving gear (14), when pump work, driven gear (13) is with respect to the eccentric motion of driving gear (14), make space generating period variation between driven gear (13) and driving gear (14), make air aspiration cavity produce negative pressure, refrigerant liquid is inhaled in gear pump immediately.
