Abstract
The invention provides an integral sealed refrigeration peripheral pump. The scheme is that the integral sealed refrigeration peripheral pump comprises a casing, a motor stator, a motor rotor, an impeller and a shaft, wherein the motor stator, the motor rotor, the impeller and the shaft are arranged in the casing. A liquid suction port connected with a liquid suction cavity and a liquid discharging port connected with a liquid discharging cavity are arranged on the casing, the motor rotor and an impeller in the casing are respectively arranged on the shaft and are synchronously operated, all bearings in the casing do not need to be lubricated by adding oils, namely, a liquid refrigerant can also have a lubricating function, and influence on a refrigeration effect caused by the fact that lubricating oil enters a refrigeration system is avoided. The pump has no leakage, is light in weight, has not shaft seal, and permanently solves the problem of leakage of a refrigeration pump, protects environment. The pump can also be used in a refrigeration system power device or used for conveying the refrigerant of a refrigerant factory. Through detection, when the pump is used in the winter working condition, more than 80% energy-saving effect can be achieved.
Description
Technical field
The present invention relates to a kind of integrated whole-closed type refrigeration peripheral 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 peripheral 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 motor stator, rotor, impeller and axle in housing and housing, 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 impeller are separately positioned on axle, and synchronous operation, the integrated totally-enclosed design of housing, be provided with bearing between impeller and rotor, be provided with bearing in impeller side, bearing and bearing are separately positioned on axle, and impeller, rotor and axle are to arrange with one heart.
Compared with prior art, the present invention has following advantage:
1, because this peripheral pump is sealed in motor stator, rotor, impeller 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 peripheral pump of this programme, mainly comprise the motor stator (2) in housing (4) and housing (4), rotor (3), impeller (7) and axle (6), there is liquid sucting port (10) to connect imbibition chamber and liquid port (1) connected drainage chamber on housing (4), it is an integral body that rotor (3) in housing (4) and impeller (7) are separately positioned on axle (6), and synchronous operation, the integrated totally-enclosed design of housing (4), frame (5) is arranged on housing (4) internal surface by interference fit, motor stator (2), bearing (11) and bearing support (8) are arranged on frame (5), bearing (11) is arranged between rotor (3) and impeller (7), bearing (9) is arranged on bearing support (8) inside, bearing (9) is connected to axle (6) one ends.
As can be seen from Figure 2, a kind of integrated whole-closed type refrigeration peripheral pump of this programme, refrigerant liquid flow through gap between motor stator (2) and rotor (3) and the gap between motor stator (2) and frame (5), make motor play the cooling down effect, because bearing (9) and bearing (11) and axle (6) are gapped, the small part refrigerant liquid flows through bearing (9) surface and enters low-pressure cavity by hyperbaric chamber, flow into again bearing (11) and locate, play lubrication.
Claims (4)
1. integrated whole-closed type refrigeration peripheral pump, mainly comprise motor stator (2), rotor (3), impeller (7) and axle (6) in housing (4) and housing (4), there is liquid sucting port (10) to connect imbibition chamber and liquid port (1) connected drainage chamber on housing (4), it is characterized in that, it is an integral body that rotor (2) in housing and impeller (7) are separately positioned on axle (6), and synchronous operation, the integrated totally-enclosed design of housing.
2. a kind of integrated whole-closed type refrigeration peripheral pump described according to claims 1, is characterized in that, this gear pump can be used for using and refrigerant conveying power plant use against Carnot's cycle medium power device.
