Description
Technical field
This invention relates to the hydraulic machinery field, relates to the Electrical Motor theory simultaneously, specifically provides a kind of efficient electromechanical rotor pump.
Background technique
Along with high development of social economy, water pump is being brought into play more and more important effect in the many fields in national economy, it is not only one of important machinery in agricultural irrigation, the urban water supply engineering, and it also is widely used in industries such as oil, chemical industry, electric power, smelting, colliery, food.Rotor pump, uses in some occasions to have remarkable advantages owing to having the lift height, moving advantages such as parts are few as a kind of water pump that is used for liquid such as water lift or transporting water comparatively commonly used at present.Yet rotor pump is because structure, the operating mode that adopts the general machine of power unit+transmission device+mechanical device to form always for many years, make and to improve and the effort that reduces production costs has been subjected to certain limitation for its efficient, simultaneously, owing to its structural reason, serious wear between slide block and slide block during work, even phenomenon of rupture takes place sometimes, between slide block and the eccentric shaft and sliding bearing abrasion relatively more serious too, and then causing pump efficiency and working life to be reduced, noise is excessive.In order to make the rotor pump better service in required industry, its important effect of performance in socio-economic development better changes its traditional machine assembly operating mode, optimizes its internal structure, improves its service behaviour and seems particularly important.
Summary of the invention
The objective of the invention is the problems referred to above at the rotor pump existence, when it is carried out optimization of inside structure, make the machine assembly operating mode of its traditional power unit+transmission device+mechanical device change into the operating mode of electromechanical, to reach the purpose of further improving its service behaviour, specifically the purpose of this invention is to provide a kind of efficient electromechanical rotor pump.
The object of the present invention is achieved like this: in a device, be provided with pump shell assembly, stator module, rotor assembly, removable magnetic baffle assembly, bearing unit, outlet pipe and intake pipe.The pump shell assembly is made up of last pump case, following pump case and pump seat, last pump case and following pump case are connected and fixed by bolt, pump seat and following pump case are cast in together, and the effect of pump shell assembly is the cylindrical space that forms a sealing, and the whole pump housing is played a supportive role; Stator module is made up of iron core, winding and stationary axle, iron core and stationary axle are connected and fixed, profile is a cylindrical shape, setting is fixed on above-mentioned sealing cylinder central zone of space, its effect is exactly to produce synchronous rotating magnetic field, and provides support and fixation radially for rotor assembly; Rotor assembly is made up of iron core, mouse cage sliver, planet external rotor balance overcoat and magnetic annulus, be hollow planet drum, be contained in by bearing housing on the cylindrical of stator module, keep gap such as between the two, planet external rotor balance overcoat adopts the camcylinder shape, cylinder barrel thickness is for becoming dimensional structure, at radius larger part thinner thickness, thicker at radius smaller part thickness, be sleeved on the outside of iron core, and be connected and fixed by screw and iron core, the magnetic annulus is the permanent magnet annulus, is embedded in planet external rotor balance external and puts.Be provided with cellular semicircle pitting at planet external rotor balance overcoat periphery.The effect of rotor assembly is to close the generation electromagnetic torque by carrying out the magnetic force lotus root with the synchronous rotating magnetic field of stator module on the one hand, is on the other hand to form the volume-variation chamber with the pump shell assembly; Removable magnetic baffle assembly is made up of moveable bulkhead, loam cake, spring and magnetic strips, is arranged between pump water inlet and the outlet pipe, and magnetic strips is embedded in moveable bulkhead end face bottom.Moveable bulkhead end face bottom is provided with cellular semicircle pitting.The effect of removable magnetic baffle assembly is divided into two alternation volume-variation chambers with rotor assembly and the formed volume-variation of pump shell assembly chamber exactly, one of them is A volume-variation chamber, pump water inlet is contained in this volume-variation chamber, another is B volume-variation chamber, and outlet pipe is contained in this volume-variation chamber; Bearing unit is made up of bearing and gland, and Bearing Installation is on stationary axle, and bearing exterior edge face and rotor assembly are fixed together, and its effect is exactly that the support rotor assembly carries out high speed rotating; Intake pipe is cast in outlet pipe and last pump case, and intake pipe and A volume-variation chamber are connected, and outlet pipe and B volume-variation chamber are connected, and the effect of inlet tube and outlet tube is with in liquid such as the current input pump housing, exports water pump again after the water pump pressurization.
The working principle of efficient electromechanical rotor pump is such: after the stator module energising, around stator module, produce a synchronous rotating magnetic field, mouse cage sliver winding in this synchronous rotating magnetic field cutting rotor assembly, produce electric current in the mouse cage sliver winding, alternating magnetic field of the same generation of this electric current, this magnetic field and synchronous rotating magnetic field are carried out the magnetic force coupling, will on rotor assembly, produce an electromagnetic torque by the magnetic force coupling, under the effect of this electromagnetic torque, rotor assembly is that fulcrum carries out high speed rotating with the stationary axle, because the rotor assembly outer rim is the eccentric external rotor balance of a planet overcoat, its radius biggest place and pump shell assembly circle tube cylinder inwall form a rotary seal band with the rotor assembly rotation like this, and removable magnetic dividing plate also makes rotor assembly outer rim and pump shell assembly circle tube cylinder inwall form a fixed sealing strip between intake pipe and outlet pipe, two sealing strips are divided into two volume-variation chambers with the volume space of being formed between rotor assembly outer rim and the pump shell assembly circle tube cylinder inwall, one is A volume-variation chamber, it contains intake pipe, another is B volume-variation chamber, and it contains outlet pipe.A, two volume-variation chambers of B are along with its volume of rotation of rotor assembly carries out opposite variation, when the volume of A volume-variation chamber from minimum to greatly to maximum again to hour, the volume of B volume-variation chamber will from be up to less to minimum again to maximum, two A, B volume-variation chamber is when carrying out above volume-variation, also carrying out the constantly variation of commutation, when above-mentioned rotary seal band and the coincidence of fixing seal band, begin commutation, at this moment the volume of A volume-variation chamber has reached maximum, and the volume of B volume-variation chamber reaches minimum, after the rotary seal band strides across the fixing seal band, A volume-variation chamber originally is for conversion into new B volume-variation chamber, B volume-variation chamber originally is transformed into new A chamber volume, just because of continuous commutation, just make above-mentioned A, the situation of sudden change appears in the variation of B volume-variation chamber volume, just because of A, two chamber volume of B are constantly repeating the variation and the commutation of above-mentioned volume, just can make pump water inlet constantly the liquid such as water in the water inlet pool are drawn into A volume-variation chamber, pass through A, the continuous conversion of B volume-variation chamber, thereby liquid such as water is constantly pressurizeed in B volume-variation chamber, and constantly pressure water stream is discharged the pump housing by outlet pipe.
