The invention relates to the technical field of centrifugal pump auxiliary equipment, and discloses a uninterruptible power supply (UPS) for oil extraction of an electric submersible centrifugal pumpin an oil field. The UPS comprises a power box, wherein a socket is fixedly arranged at a lower part of an outer surface of a rear end of the power box, a jack structure is arranged in the socket, andtwo groups of metal sheets are fixedly arranged in the jack structure and are symmetrically arranged along a central line of the jack structure. In the UPS for oil extraction of the electric submersible centrifugal pump in the oil field, a guide plate is arranged, and protection blocks can be enabled to stably slide along a sliding groove structure of the guide plate when the protection blocks are extruded by an external force and a spring resets; the protection blocks are arranged, the two groups of protection blocks are matched closely due to deformation elasticity of the spring, the metalsheets in the socket are isolated with the outside, the metal sheets are prevented from being polluted by oil gas in an environment, and accident scratch is prevented.
Description
technical field [0001] The invention relates to the technical field of centrifugal pump auxiliary equipment, in particular to a UPS power supply for oil recovery of electric submersible centrifugal pumps in oil fields. Background technique [0002] A centrifugal pump refers to a pump that delivers liquid by the centrifugal force generated when the impeller rotates. Before the pump is started, the pump casing and the suction pipe must be filled with water, and then the motor is started so that the pump shaft drives the impeller and the water to rotate at a high speed. Centrifugal movement, thrown to the outer edge of the impeller, flows into the pressure water pipeline of the pump through the flow channel of the volute pump casing, the basic structure of the centrifugal pump is composed of six parts, namely the impeller, the pump body, the pump shaft, the bearing, and the sealing ring , stuffing box. [0003] In the oil extraction industry, electric submersible centrifugal p...
