Abstract
An oil-immersed electric submersible pump capable of automatically regulating pressure of a motor chamber comprises an oil-immersed electric submersible pump, and is characterized in that a through hole is formed on the top of a lower end cover of the oil-immersed electric submersible pump; and an elastic pad is connected at the bottom of the through hole in a sealed way. When the motor temperature rises to expand oil in the motor chamber, the elastic pad is pressed and elastically deformed to increase the space of the motor chamber, so that the pressure in the motor chamber is automatically regulated; when the motor temperature falls and the oil pressure falls, the elastic pad returns to the original position and the motor chamber is full of oil, so that the radiation of the motor and the lubrication of a bearing are ensured and the motor runs safely and reliably.
Description
Technical field
The utility model relates to a kind of pump, particularly a kind of oil immersion type electric underwater pump of motor cavity automatic Regulation.
Background technique
Be the normal safe operation of assurance electric pump, the motor cavity domestic demand filling machine oil of oil immersion type electric underwater pump, but as in motor cavity, filling with oil; Along with motor increases working time; Particularly under motor overload runnability, the oil temperature raises fast, volumetric expansion, causes motor to go up easily.For avoiding taking place this type of explosive accident, way commonly used at present is that the oil in the motor cavity is not filled it up with, but oil is few, can cause bearing under the oil-free lubrication state, to move again, can burn motor equally.
Summary of the invention
The purpose of the utility model is in order to solve the problems of the technologies described above, and provides in a kind of motor cavity oil pressure can to regulate the oil immersion type electric underwater pump of motor cavity automatic Regulation safe and reliable to operation automatically.
The purpose of the utility model is achieved in that a kind of oil immersion type electric underwater pump of motor cavity automatic Regulation; Comprise existing oil immersion type electric underwater pump; It is characterized in that having a through hole via bottoms cushion that is tightly connected at the lower end cap end face of oil immersion type electric underwater pump.
The utility model is owing to adopt above architecture advances, when motor temperature is increased to the oil that makes in the chamber when expanding, and compressing cushion generation elastic strain and the motor cavity space is increased; Pressure in the self-regulation motor chamber; After motor temperature reduced, oil pressure descends, cushion recovered the origin-location, makes motor cavity be full of oil; Thereby guarantee heat radiation, the bearing lubrication of motor, safe and reliable to operation.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Combine the accompanying drawing illustrated embodiment that the utility model is made detailed description at present.
As shown in Figure 1; A kind of oil immersion type electric underwater pump of motor cavity automatic Regulation; Comprise existing oil immersion type electric underwater pump 1, have a through hole 3 at lower end cap 2 end faces of oil immersion type electric underwater pump 1, through hole 3 bottoms are disposed with resilient rubbber cushion 4, hollow pressing plate 5; By screw 6 pass hollow pressing plate 5 peripheries, resilient rubbber cushion 4 is fixedly connected with lower end cap 2 end faces, resilient rubbber cushion 4 is with through hole 3 sealing.
