Description

Be used to connect the equipment of motor type driver element and pump unit
Technical field
The present invention relates to a kind of equipment that is used to connect motor type driver element and pump unit; It comprises a cage type part; This cage type part surrounds and is used for the mechanical connector spare through drive unit drives pump unit, and driver element distolaterally is connected on the said cage type part and pump unit axial another relative distolateral being connected at least indirectly on the said cage type part at least indirectly at one.
Background technique
Such equipment is known and particularly is used in the dry type rotor pump.The cage type part mechanically is connected the pump unit with driver element by the mode of modular structure form.The cage type part constitutes the member of sleeve shape, and this member surrounds driving element, and wherein, driving element at one end rotationally fixedly is connected and is connected with driver element at the other end rotationally fixedly with the pump unit.The cage type part on the one hand with the pump unit, on the other hand with driver element between be connected usually and realize through flange.The axis of the live axle of pump shaft line, driver element and cage type part is aligned with each other like this at this, makes them be located on the same line.
The interface unit that is surrounded by the cage type part for example can perhaps also can form through speed changer through clutch; Wherein clutch or speed changer are connected with the live axle of driver element at its driving side rotationally fixedly; And the outlet side rotationally fixedly of clutch or speed changer is connected with pump shaft; There is an active wheel in a end at this pump shaft, so that the medium of delivering liquid when moving in the pump unit.For the transition part between canned pump unit and the cage type part, in the zone of the axle that drives active wheel, use mechanical sealing spare, particularly bearing ring seal spare usually.Bearing ring seal spare is surrounded by the liquid that is transferred when pump operation, and this liquid works to be used for the oiling agent of bearing ring seal spare on the one hand, also plays freezing mixture but then.
If in the pump unit, dry-running takes place, then there is such danger, i.e. bearing ring seal spare heating and fracture strongly owing to lack lubricated owing to lack liquid.And if then, then leak owing to becoming packing less bearing ring seal spare again with the pump chamber of the liquid filling pump unit that will carry.
In order to detect the known different supervisory device of dry-running.For example EP 1 510 698 A2 disclose a kind of dry-running protective gear that is used for drive motor and pump, and it comprises that one is connected the pipe fitting on the pump case, and this pipe fitting has the fluid detector of condenser type transversal switch form.Pipe fitting comprises the solenoid valve that is used to handle venting gas appliance; Wherein solenoid valve and fluid detector are connected on the electronic equipment jointly; Can irrespectively freely select with the location of pumping system though this electronic equipment has the spatial arrangement of running state display device and this electronic equipment, preferably spatially turning up the soil with the separation of dry-running protective gear is arranged on the pump.
This distributed earth for example in Surveillance center inner or in switch cubicle the shortcoming away from the monitoring electronic equipment of pump assembly setting be, between pump assembly and monitoring electronic equipment, must lay additional electric lead.This is costliness and bothersome.Be noted that in addition lead can be by mechanical failure, for example because crooked or extruding when professionally laying or because the biting of animal.In addition, the electromagnetic coupling in the lead can negatively influence the data transmission through these leads.Therefore must use by the lead that enough shields, this lead causes higher cost again.Last also be noted that on the one hand the connecting terminal between pump assembly and the lead and on the other hand the connecting terminal between monitoring electronic equipment and lead can be hindered by mechanical load or corrosion, thereby when transmission, also can have error source here.Such error source in data transmission can lead to errors on the one hand alarm, cause not discern vicious running state on the other hand.In this case, the running state of monitoring pump unit or driver element will be unnecessary.
Another shortcoming in the monitoring electronic equipment of distributed arrangement is, the pump technician sees monitoring the running state display device of electronic equipment and pump assembly on the other hand on the one hand simultaneously.But he must conversion back and forth between them in order to check electronic equipment and unit.Examining of the state that is presented at the error condition on the monitoring electronic equipment and in fact in pump assembly, exists because distributed arrangement is impossible; Because when the pump technician is not in Surveillance center or by the switch cubicle, the error condition that on the monitoring electronic equipment, shows can not be through the inspection to pump assembly perhaps is verified its check according to the acoustics kink characteristics.
Usually known, the electronic equipment that will be used for control drive unit is arranged in housing, and this housing is set directly on the motor that forms driver element.Usually, such electronic equipment is integrated into this just being fixed in the terminal box on the electric machine casing of existence.
The monitoring electronic equipment is arranged on the electric machine casing and can causes different shortcomings.For example, the monitoring electronic equipment can suffer the used heat by the motor generation, and this damages each member, particularly causes member aging quickly.In addition, the strong electromagnetic field of motor obviously influences the Measurement and Data Processing of monitoring electronic equipment.In order to guarantee reliable data processing, the high request to the electromagnetic field of shield electric machine also is essential here.This causes the obviously higher cost and the obvious higher technology of the structural design that is used to monitor electronic equipment to expend equally.Another shortcoming that the monitoring electronic equipment is arranged on the electric machine casing is for the essential space requirement of monitoring electronic equipment.Pump assembly is arranged on inaccessible especially position and usually particularly in narrow space situation.In addition, under the situation of a plurality of pump assemblys that is arranged side by side, the structure space that is provided obviously is restricted.Therefore the housing of monitoring electronic equipment in holding on the electric machine casing can radially stretch out from this electric machine casing and according to making that in the difference that electric machine casing is arranged it is impossible such pump assembly being packed into the narrow structure space.
At last, another shortcoming of existing technology is, mechanically is fixed on the pump assembly or for the electrical connection between monitoring electronic equipment and pump assembly, they must be coordinated with each other in order to monitor electronic equipment.Therefore, pump assembly must have fixedly possibility and the electric contact element that matees with the monitoring electronic equipment.Because this coherence and disadvantageously be that the motor type driver element all can not be changed without a doubt and substituted by other model with the monitoring electronic equipment.
Summary of the invention
Therefore; The objective of the invention is to; A kind of pump assembly of monitoring electronic equipment or having the monitoring electronic equipment is provided, motor type driver element and monitoring electronic equipment that it overcomes the shortcoming of existing technology and under the situation of structure space demand minimum, guarantees high safety in operation and accessibility and guarantee irrespectively to change with model pump assembly.
Said purpose realizes through a kind of pump assembly according to claim 16 and through a kind of equipment according to claim 1, that in this pump assembly, use.Favourable improvement project of the present invention is explained in the dependent claims.
