[0002] A submersible electric pump (FET) is a device used in oil well production to extract crude oil or other liquids from underground reservoirs. However, existing FETs are typically exposed to the external environment during use, and their exterior is often subject to wear. Long-term wear can damage internal components, affecting the lifespan of the FET. Furthermore, FETs generate considerable noise during operation, impacting the working environment.

[0014] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0015] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] like Figure 1 As shown, a noise reduction protective cover for a submersible electric pump includes a protective cover shell 1, a noise reduction vacuum chamber 2, a noise reduction temperature control chamber 3, an electric pump inlet pipe channel 4, an electric pump outlet pipe channel 5, a sealing noise reduction ring 6, heat dissipation fins 7, a handle 8, a fixing base 9, a connecting hole 10, a sound insulation sealing ring 11, and an injection / discharge port 12.

[0019] The bottom of the protective cover 1 is provided with a fixing base 9, and the fixing base 9 is provided with a connecting hole 10, so as to fix the protective cover 1 to the periphery of the electric pump.

[0020] The protective cover 1 has a noise reduction vacuum chamber 2 inside its side wall. By drawing a vacuum, the noise reduction capability of the protective cover 1 can be improved.

[0021] The top of the protective casing 1 is equipped with a noise reduction and temperature regulation chamber 3, which is filled with a phase change medium. An injection / exhaust port 12 is located on one side of the noise reduction and temperature regulation chamber 3, and a sealing cap is provided on the injection / exhaust port 12. A phase change medium, such as liquid paraffin, can be injected into the noise reduction and temperature regulation chamber 3 through the injection / exhaust port 12. This medium can absorb noise and also absorb the heat generated during the operation of the electric pump, preventing internal overheating.

[0022] The protective cover 1 has an electric pump inlet pipe channel 4 and an electric pump outlet pipe channel 5 on its side wall. The inner ends of the electric pump inlet pipe channel 4 and the electric pump outlet pipe channel 5 are both filled with sealing and noise reduction rings 6.

[0023] The inner ends of the electric pump inlet pipe channel 4 and the electric pump outlet pipe channel 5 are both tapered structures, and the sealing noise reduction ring 6 is also tapered.

[0024] The sealing and noise reduction ring 6 can seal the inlet and outlet pipe positions, thereby reducing noise. The conical structure can improve its application range and provide a better sealing effect.

[0025] The lower end of the inner wall of the protective cover 1 is provided with an annular groove, and a sound-insulating sealing ring 11 is provided in the annular groove. The sound-insulating sealing ring 11 can form a seal at the bottom, thereby reducing noise.
