Abstract
The utility model relates to an immersible pump provided with a cable sealing structure. The immersible pump provided with the cable sealing structure comprises a main cable, a locking nut, a flat washer, a sealing ring and a motor casing. The main cable penetrates into the motor casing through a sealing hole, a cable core is arranged in the main cable, the cable core is connected with a lead wire of an immersible pump motor, the sealing ring, the flat washer and the locking nut are sequentially arranged in the sealing hole from top to bottom, and the locking nut drives the flat washer to squeeze and deform the sealing ring when tightly screwed up to seal the sealing hole. The immersible pump provided with the cable sealing structure is simple in structure, low in cost, favorable for production, and capable of preventing water from entering the motor along with the surface skin of the cable. Potting glue can be arranged on the connecting position between the cable core and the lead wire of the immersible pump motor, the situation that water enters the motor along the clearance of each phase line core or along a copper wire when the surface skin of the cable is damaged is avoided, and therefore the water is prevented from entering the motor to damage the motor.
Description
Technical field
The utility model relates to the improvement of the sealing configuration of submerged cable in a kind of submersible pump, and particularly a kind of submersible pump with cable seal structure of simple in structure, good sealing effect belongs to submersible pump series products technical field.
Background technique
Existing submersible pump with cable seal structure generally has two kinds, and a kind of is the bolt-type sealing configuration, as shown in Figure 1, comprises gland nut 8, molded plug 9, terminal 10; The form of molded plug 9 is partly made in the wiring of cable, directly molded plug 9 is inserted on the female seat of casing during assembling, with terminal 10 motor down-lead is connected with cable, again with gland nut 8 locking, this sealing configuration be usually used in single-phase or the submersible pump than Thin cable on, when cable is thicker, the structure of making plug is relatively more difficult, cost is higher, and when water pump voltage is high, and the terminal between heterogeneous causes puncture easily; Another kind is the sealant pouring and sealing structure, as shown in Figure 2, comprises leader cable 21, sealant layer 41, thermal-shrinkage finger sleeve of cable 42, cable core 43, heat-shrinkable T bush 44, sealing cable terminal head 45; Cable (comprising triple line and ground wire) separately is potted on the upper end cap of submersible pump, cable core 43 is connected with the motor down-lead wiring, be coated with sealant layer 41 in the outside of leader cable 21, the front end of cable core 43 is coated with thermal-shrinkage finger sleeve of cable 42, the rear end of cable core 43 is coated with heat-shrinkable T bush 44, and the end of cable core 43 is connected with sealing cable terminal head 45; This sealing configuration cable is potted on the upper end cap, is unfavorable for later detachable maintaining, and cable and the technological operation of motor down-lead wiring part sealing configuration are cumbersome.
The model utility content
The utility model purpose is the submersible pump with cable seal structure that a kind of simple in structure, good sealing effect is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of submersible pump with cable seal structure comprises leader cable, locking nut, plain washer, seal ring, motor casing; Described leader cable penetrates in the motor casing by closed hole; Be provided with cable core in the described leader cable; Described cable core links to each other with the lead-in wire of motor for submerged pump; Described seal ring, plain washer, locking nut are successively set in the closed hole from down to up; Drive plain washer during described locking nut screwing with seal ring extrusion-deformation, closed hole is sealed.
Preferably, the joint of described cable core and motor down-lead near removing one section isolation layer on the position of leader cable insulated hull, is exposed inner copper cash, and encapsulating is set; The copper cash that described encapsulating will expose coats, and leader cable is blocked sealing.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
The submersible pump with cable seal structure of the utility model scheme, simple in structure, cost is low, be convenient to produce, can prevent that sealing is in cable skin enters motor, also avoided simultaneously after the cable skin wearing and tearing, water enters the situation of motor along the gap of each phase core or along copper cash, thereby prevents that motor entering water from damaging.

Accompanying drawing 2 is the schematic representation of sealant pouring and sealing structure in the prior art;
Accompanying drawing 3 is a kind of partial sectional view with submersible pump of cable seal structure of the present utility model;
Accompanying drawing 4 is a kind of encapsulating place structural representation with submersible pump of cable seal structure of the present utility model;
Wherein: 1, leader cable; 2, locking nut; 3, plain washer; 4, seal ring; 5, motor casing; 6, cable core; 7, encapsulating.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 3-4 is a kind of submersible pump with cable seal structure described in the utility model, comprises leader cable 1, locking nut 2, plain washer 3, seal ring 4, motor casing 5; Described leader cable 1 penetrates in the motor casing 5 by closed hole; Be provided with cable core 6 in the described leader cable 1; Described cable core 6 links to each other with the lead-in wire of motor for submerged pump; Described seal ring 4, plain washer 3, locking nut 2 are successively set in the closed hole from down to up; Drive plain washer 3 when described locking nut 2 is tightened with seal ring 4 extrusion-deformations, closed hole is sealed; Described cable core 6 and the joint that motor for submerged pump goes between near removing one section isolation layer on the position of leader cable 1 insulated hull, expose inner copper cash, and encapsulating 7 are set; The copper cash that described encapsulating 7 will expose coats, and leader cable 1 is blocked sealing.
The submersible pump with cable seal structure of the utility model scheme, simple in structure, cost is low, be convenient to produce, can prevent that sealing is in cable skin enters motor, also avoided simultaneously after the cable skin wearing and tearing, water enters the situation of motor along the gap of each phase core or along copper cash, thereby prevents that motor entering water from damaging.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
