AI Technical Summary

Benefits of technology

This new type of power supply for pipelines uses an air cooled (AC) machine instead of conventional ones due to its lower noise level compared to previous designs. It also improves efficiency by reducing friction between components without adding any extra parts like fans or bearings. Additionally, this technology reduces thermal stress from high temperatures while still maintaining effective lubricating properties over long periods of time. Overall, these technical improvements result in quieter, more reliable equipment used in various industries such as oil refining operations.

Problems solved by technology

This technical problem addressed in this patented text relates to finding ways to reduce or eliminate noise emitted during use of electronic devices such as motors for hydraulic power transmission (MET) applications.

Embodiment Construction

[0017] During the operation of the electric pump, the impeller 1 rotates to generate a head, the outlet of the pump body 2 is high pressure, and the inlet is low pressure. Drainage holes are opened on the outlet flange of the centrifugal pump. The flow channel of the outlet flange of the high-pressure water pump passes through the filter screen 3 and enters the decompression pipe 5 for decompression. A dredging screw 4 is added to the drainage hole to facilitate cleaning. The decompressed water is introduced into the motor condensing system, and its flow rate is controlled by the connected throttle valve 6. The throttle valve 6 is connected to the first bearing cooling chamber 7 through a conduit, and the depressurized water enters the condensing motor casing 8 through the first bearing cooling chamber 7 through the inlet 16, and forms a double "S" shape with the copper pipe 14 Flow around the motor housing removes heat. The housing is made of aluminum, the copper tube 14 is ...

Abstract

The invention discloses a low-noise stable horizontal direct-connected electric centrifugal pump which comprises a filter screen (3), a dredging screw (4), a pressure reduction pipe (5), a throttling valve (6), a first bearing cooling containing cavity (7), a condenser motor shell (8), a second bearing cooling containing cavity (9), a connecting pipe (10), a jet pipe (11), a water inlet (16) and a water outlet (17). A traditional air cooling motor type is changed into a water cooling structure, the first bearing cooling containing cavity (7) and the condenser motor shell (8) are used for cooling a motor bearing, a stator and a rotor releasing heat, a formed jet guide device is used for improving stability of the pump running under an off-design condition, so that radiation noise of the centrifugal pump in the running process is effectively reduced, running stability of the centrifugal pump is improved, and the 'quiet' design of a pipeline system is realized.
