Problems solved by technology

[0002] At present, the failure of the seal of the submersible motor in oil field production is an important reason for the damage of the submersible motor
Submersible motors are usually sealed with O-rings. Under high-pressure and high-temperature working conditions, O-rings will be squeezed into the sealing gap and cause gap bites, resulting in seal failure, and crude oil seeps into the submersible motor, resulting in The submersible motor is damaged, resulting in large economic losses

Embodiment Construction

[0009] The structure and implementation mode of the present invention will be further explained below in conjunction with the accompanying drawings.

[0010] Such as figure 1 As shown, a new sealing ring for submersible motors includes: left sealing lip 1, right sealing lip 2, ring body 3, and semicircular notch 4. The present invention is made of fluorine rubber, the left sealing lip 1 and the right sealing lip 2 are located on the top of the ring body 3, and are symmetrically distributed, and the semicircular notch 4 is located in the middle of the bottom of the ring body 3. The left sealing lip 1 and the right sealing lip 2 can both produce a sealing effect under the action of pressure, and play the role of double sealing; the left and right sides of the ring body 3 are vertical cut surface structures, which will not be squeezed into the sealing gap and cause bites.

Abstract

The invention discloses a novel sealing ring for a submersible motor. The novel sealing ring comprises a left sealing lip, a right sealing lip, a ring body and a semicircular notch. The novel sealing ring has the left sealing lip and the right sealing ring so as to achieve the dual sealing effect under the pressure effect, is reasonable in structural design, cannot be squeezed into a sealing gap to be damaged in a meshed manner, and is made of fluororubber so as to effectively slow down the ageing and the corrosion and to prolong the service life.

Description

technical field [0001] The invention relates to a novel sealing ring for a submersible motor, which belongs to the field of sealing technology research. Background technique [0002] At present, the seal failure of submersible motors in oilfield production is an important cause of damage to submersible motors. Submersible motors are usually sealed with O-rings. Under high-pressure and high-temperature working conditions, O-rings will be squeezed into the sealing gap and cause gap bites, resulting in seal failure, and crude oil seeps into the submersible motor, resulting in The submersible motor is damaged, resulting in large economic losses. Contents of the invention [0003] In order to overcome the above problems, further improve the sealing performance of the sealing ring, and prolong the service time of the submersible motor, a new type of sealing ring for the submersible motor has been invented. The novel sealing ring for the submersible motor has the advantages of ...
