Abstract
The utility model relates to an improved QY model submersible pump which belongs to the technical field of the non positive displacement pump. The gap of the stator and rotor of the motor is changed into the dry type on the basis of the existing QY model submersible pump. A rotating shaft is connected with the stator by a sealed bearing. The height of the upper opening of the nylon bearing seat is parallel with the lower step of the sealing ring. The sealing ring is hermetically connected with a shaft sleeve by an elastic rubber ring. The improved QY model submersible pump can save energy and prolong the service life of the submersible pump.
Description
The utility model relates to this technical field of non-varactor pump, particularly a kind of submersible pump.
Present QY type submersible pump, the space between the stator and rotor of its motor part is full of machinery oil No. 5, and its effect is cooling, heat radiation, to bearing lubrication.But this oil viscosity is low, and greasy property is poor.During the electric pump operation, oily temperature rise, its viscosity is lower, causes the bearing ravine sliding bad, influences bearing life.The oil temperature rise, its volumetric expansion, pressure raise, and easy abrading block under the sealing case of jacking upper end makes moisture content in the sealing case enter motor internal and causes the winding damage of making moist.In the submersible pump running, because of the reactive loss of the resistance expanded motor of No. 5 machinery oil, power consumption increases, and causes energy waste.Motor bearings adopts 305,204 bearings, and this class bearing is with No. 5 engine oil lubrication, and its greasy property is relatively poor, is easy to cause the bearing life shortening.Open height is higher than the seal ring leave from office on the nylon bearing seat, easily accumulates silt, accelerates the wearing and tearing of seal ring.Spring ring easy-to-rust on the seal ring, ineffective, cause the shortening in seal ring life-span.
The utility model provides a kind of improved QY type submersible pump at above-mentioned problems of the prior art.Space between the stator and rotor of this submersible pump changes dry type into by being full of No. 5 machinery oil, is connected by stuffing box bearing between the rotating shaft of motor part and stator, and open height is equal with the seal ring leave from office on the nylon bearing seat, and the spring ring on the seal ring is used the elastic caoutchouc circle instead.Can reach purpose energy-conservation and that prolong the submersible pump life-span.
The utility model is achieved through the following technical solutions: this submersible pump is the improvement to QY type submersible pump, is made up of water pump, motor and sealing three parts.Be dry type between the stator and rotor space of motor, be connected by stuffing box bearing between rotating shaft and stator that open height and seal ring are left office equally on the nylon bearing seat, seal ring is connected with rotating shaft sealing by the elastic caoutchouc circle.Be dry type between stator and rotor, promptly reduced the running resistance of rotor, reduce reactive loss, but energy saving, reduce temperature rise.Hot turgor pressure power because of air is lower again, has avoided No. 5 machine oil volumetric expansions when oily temperature rise, has easily backed down abrading block under the sealing case and the problem that makes the moisture content in the sealing case enter motor internal.Be connected by stuffing box bearing between rotating shaft and stator, the sealing bearing adopts soda grease or lithium grease high speed butter lubricated, and its greasy property is higher than machinery oil No. 5, can prolong the life-span of stuffing box bearing.Open height is equal with the seal ring leave from office on the nylon bearing seat, can reduce silt and accumulate, and reduces the wearing and tearing of seal ring.Seal ring is connected with rotating shaft sealing by the elastic caoutchouc circle, and the elastic caoutchouc circle is difficult for corrosion, and the life-span is longer.
Accompanying drawing 1 is a kind of longitudinal section schematic representation (stuffing box bearing does not draw) of improved QY type submersible pump.Accompanying drawing 2 is sectional arrangement drawings of the seal ring of its hermetic unit, and accompanying drawing 3 is sectional arrangement drawings of the nylon bearing of its hermetic unit, and accompanying drawing 4 is sectional arrangement drawings of its motor part stuffing box bearing.
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail: a kind of improved QY type submersible pump, form by water pump (1) sealing (2), motor (3) three parts.The space (9) of former QY type submersible pump between stator (12), rotor (11) is full of machinery oil No. 5, and this oil viscosity is low, and greasy property is poor, and during the submersible pump operation, temperature raises, and its viscosity is lower, causes bearing (8) insufficient lubrication, influences bearing life.The oil temperature rise, the following abrading block of integral sealing box (10) in the hermetic unit (2) is easily backed down in the machine oil volumetric expansion, makes moisture content in the integral sealing box enter motor (3) inside and causes the winding damage of making moist.But the reactive loss of the resistance expanded motor of machinery oil in addition, power consumption increases, and causes energy waste.Improved QY type submersible pump, between the stator (12) of its motor part (3), the space (9) of rotor (11) is dry type, rotating shaft (6) is connected by stuffing box bearing (8) with stator (12), sealing bearing (8) refers to 180204,180305 bearings, 204,305 bearings that are about to former QY type submersible pump change 180204,180305 bearings into, sealing bearing (8) adopts soda grease formula or lithium grease high speed butter to lubricate, its greasy property is higher than machinery oil No. 5, can prolong the life-span of stuffing box bearing (8).Stuffing box bearing does not draw among Fig. 1, and the concrete structure of sealing bearing is seen Fig. 4.(15) suitable for reading of former nylon bearing seat (5) are higher than the leave from office (16) of seal ring (4), easily cause silt to accumulate, and increase seal ring (4) wearing and tearing.Improved QY type submersible pump makes (15) suitable for reading of nylon bearing seat (5) equal with the leave from office (16) of seal ring (4), seal ring (4) is contained on the nylon bearing seat (5), the leave from office (16) of seal ring (4) promptly forms the plane with (15) suitable for reading of nylon bearing seat (5), promptly solved the problem that silt accumulates, former QY type submersible pump seal ring (4) is tightly connected by spring ring and axle sleeve (7), spring ring easy-to-rust and ineffective causes seal ring (4) lost of life.A kind of improved QY type submersible pump, seal ring (4) is tightly connected by elastic caoutchouc circle (17) and axle sleeve (7).Elastic caoutchouc circle (17) is difficult for corrosion, and the life-span is longer.
The stator (12) of former QY type motor for submerged pump part (3), the space (9) between the rotor (11) are full of machinery oil No. 5, mainly are cooling, heat radiation, to the effect of bearing lubrication.Improved QY type submersible pump still can solve heat dissipation problem preferably, because after changing dry type between the stator (12), rotor (11), has reduced the running resistance of rotor, reduce reactive loss, but energy saving reduces temperature rise.Because this submersible pump moves in immersing fully, make external refrigeration by water again, body fuselage is to make with heat conduction fast cast iron and metal village material.So can solve the submersible pump heat dissipation problem preferably.
Former QY125-40-3 submersible pump is power consumption 3.6-3.8 degree per hour, power consumption 2.8 degree per hour after the repacking, fractional energy savings 22.2%.
