Abstract
The utility model discloses a submersible motor with a sealed connecting wire. In the submersible motor, a motor wire-connecting cavity and a motor cavity are completely isolated by using a seal plate, the seal plate is only provided with two small holes used for connecting of a power cable and a motor outgoing wire and allowing a control cable to access into the interior of the motor cavity. An insulator covers on a connection part between the power cable and the motor outgoing wire and plays the roles of supporting and sealing. A control cable gland covers the control cable at an access point of the seal plate, so that a favorable seal effect is achieved and the independence of the motor cavity and the motor wire-connecting cavity is ensured. By means of the structural changes of the submersible motor disclosed by the utility model, the seal and isolation performance between the motor wire-connecting cavity and the motor cavity is enhanced, the seal reliability of the motor cavity is improved, and the faults of the submersible motor are reduced.
Description
Technical field
The utility model relates to the water treatment facilities technical field, particularly relates to a kind of submersible motor of sealed wiring.
Background technology
Immersible pump (submersible type dredge pump, submersible type axial-flow pump, submersible type mixed-flow pump), because of the pump configuration compactness, convenient for installation and maintenance; The pumping plant investment is little, and noise is low, the motor cooling condition is good, the pumping plant good operation conditions; Pumping plant builds up underground type, can save superstructure, does not influence surface structures or greening, can build into garden landscape type pumping plant, favored by the user, thus control flood and drain flooded fields, field such as field irrigation, urban construction, water conservancy construction is used widely.Be the substitute products of traditional water pump.
The quality critical of immersible pump is decided by the quality quality of submersible motor, and the work because immersible pump is dived beneath the water, so the sealing property of motor will directly influence the quality of water pump.Large power high voltage motor particularly, voltage reaches 3kV, 6kV, 10kV in case motor leaks electric leakage, will produce very serious consequence, causes heavy losses or personnel casualty accidents.
Sealing between motor lead-out wire and the diving cable, it is particularly important that the sealing between motor wire connection cavity and motor cavity seems.
As shown in Figure 1, existing submersible axial flow pump submersible motor, the both sides of dividing plate communicate between motor cavity and the motor wire connection cavity, be used for the external electric cable and be linked into motor cavity, in case the motor wire connection cavity leaks, water inlet, water (or steam) will enter motor cavity, causes the motor water inlet or makes moist, the electrical machine insulation decreased performance causes burn-down of electric motor or electric leakage.In order to prevent that above-mentioned accident from taking place, be sealed in technical having much room for improvement between motor wire connection cavity and motor cavity.
The utility model content
Technical problem to be solved in the utility model is the submersible motor of a kind of sealed wiring of proposing at existing technical problem in the above-mentioned prior art; this submersible motor has been strengthened the independence between motor cavity and the motor wire connection cavity; strengthened the sealing reliability of motor cavity; the protection motor is avoided damaging, and has reduced the failure rate of electric pump.
