Description
Technical field
The utility model relates to a kind of rotor pump.
Background technique
Rotor pump is widely used in fields such as food, chemical industry, machinery as the power plant of mass transport.The sealability of rotor pump is very big to the influence in working life of rotor pump.
Present rotor pump is generally only considered the heatproof of pump body in design, then left Sealing producer for for the heatproof problem of mechanical seal.When being used to carry normal temperature or temperature to be lower than 120 ℃ medium, rotor pump is generally selected the normal temperature sealing for use, does not seal Cooling Design.Be used to carry be higher than 120 ℃ during less than the medium below 220 ℃, rotor pump is installed the wavy metal seal of tube.If carry the medium that is higher than more than 220 ℃, be the radiating effect that guarantees that the mechanical seal friction is paid, then must be to metal bellows sealing carrying out water cooling.Because the mechanical seal volume is less, Sealing producer then designs the wavy metal seal of tube of a very little band cooling chamber under this smaller volume, adopt the water cooling of unit loading type metal bellows sealing strip, to reach the effect of cooling mechanical seal, owing to use non-soft water to produce fouling on metal bellows, the metal bellows hardening is followed the string, cause seal failure, occur revealing, what influence was produced normally carries out.And, be open type because mechanical sealed space is installed, can't lead to cooling water.If with this space sealing, lead to cooling water on this architecture basics, cooling water might enter lubricating cavity by the lubricating cavity oil sealing, damages bearing in the running.Therefore, present pump structure can not be set up the sealing cooling chamber.
The model utility content
The utility model is in order to overcome deficiency of the prior art, to provide a kind of and can realize that sealing configuration is fully cooled off in the high temperature media course of conveying, improving elevated-temperature seal performance and the rotor pump of sealing life.
The utility model is achieved through the following technical solutions:
A kind of rotor pump, comprise bearing support, the pump housing, driving shaft, driven shaft, described driving shaft is installed on the bearing support by drive shaft bearing, described driven shaft passes through the driven shaft Bearing Installation on bearing support, be respectively arranged with bearing lubrication chamber and lubricating cavity oil sealing with drive shaft bearing and the corresponding position of driven shaft bearing on the described bearing support, it is characterized in that, the joint of the described bearing support and the pump housing is provided with cooling chamber, the junction surface of the described bearing support and the pump housing is provided with seal groove, and the O RunddichtringO is installed in the described seal groove; Be respectively arranged with outside framework oil seal on the driving shaft of the relative side of described bearing support and the driven shaft with the bearing lubrication chamber, be provided with clearance space between described outside framework oil seal and the lubricating cavity oil sealing, be respectively arranged with mechanical sealing mechanism on driving shaft in the described cooling chamber and the driven shaft, the bi-side of described cooling chamber are respectively arranged with sealing mechanism window are installed, with the corresponding cooling chamber of outside framework oil seal place the cooling chamber lid of sealing two sealing mechanisms installation windows is installed, the cooling chamber of both sides covers and is respectively arranged with cooling liquid inlet and cooling liquid outlet; Cooling chamber lid, O RunddichtringO, outside framework oil seal, bearing support and the pump housing make cooling chamber form the cavity of sealing.
Described mechanical sealing mechanism is the mechanical seal of waveform spring form, comprises stationary ring, rotating ring, waveform spring and rotating seat, and described stationary ring is installed in the pump housing back side; Described rotating seat, waveform spring and rotating ring be an integral installation on driving shaft or driven shaft, and fastening by fastening jackscrew and driving shaft or driven shaft.
Stationary ring in the waveform spring mechanical sealing mechanism, rotating ring are cemented carbide, and the O RunddichtringO is resistant to elevated temperatures carbon fibre material.
The utlity model has following technique effect:
Rotor pump of the present utility model has designed bigger cooling chamber cooperative mechanical sealing and has used in the joint of the bearing support and the pump housing, because cooling fully, and non-scaling on the waveform spring of mechanical seal, in big cooling chamber, there is not scale formation yet, make the fed sheet of a media temperature can reach 400 ℃, mechanical seal extends to more than 0.5 year working life.After adopting this technology, in the selection of mechanical seal, can adopt the conventional machinery sealing, avoid selecting for use the wavy metal seal of tube and the unit loading type wavy metal seal of tube, greatly reduce the overall cost of pump.
