Frequency conversion cabinet used in beam-pumping unit in oil field

Abstract

The invention relates to the technical field of frequency conversion cabinets, and discloses a frequency conversion cabinet used in a beam-pumping unit in an oil field. The frequency conversion cabinet comprises a cabinet body, a partition plate is fixedly installed in an inner cavity of the cabinet body, a cooling pump located below the partition plate is fixedly installed in the inner cavity ofthe cabinet body, on one of the cooling pump is connected with one end of a flow guide pipe in a penetration manner, the other end of the flow guide pipe penetrates through and extends to the interiorof the cabinet body, the flow guide pipe extends to one side in the cabinet body and is connected with one end of a horizontal pipe in the penetration manner, and the other end of the horizontal pipeis connected with one side of the flow guide pipe in the penetration manner. According to the frequency conversion cabinet used in the beam-pumping unit in the oil field, by means of the cooperativeuse of an upper mounting plate, an upper supporting plate, an expansion link, a spring, a lower supporting plate and a lower mounting plate, the cabinet body is damped, thereby avoiding the problem that the frequency conversion cabinet shakes on roads with jolt or uphill and downhill road segments in a moving process of the frequency conversion cabinet, resulting in damage to electronic parts andcomponents therein, so that the practicability of the frequency conversion cabinet is improved.

Description

technical field [0001] The invention relates to the technical field of frequency conversion cabinets, in particular to a frequency conversion cabinet used in beam pumping units in oil fields. Background technique [0002] The frequency conversion cabinet uses the control cabinet of the drive power device of the frequency converter, because of its good starting performance, speed regulation performance and energy-saving effect, it has become the currently popularized power drive method. [0003] The current frequency conversion cabinet has a movable frequency conversion cabinet. During the moving process, due to the bumps on the road or the up and down slopes, the frequency conversion cabinet is very easy to shake, causing damage to its internal electronic components. In addition, the existing frequency conversion The cabinet usually uses air cooling to dissipate heat inside it. However, the air cooling method is likely to cause dust accumulation on the filter element. After ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a frequency conversion cabinet used in beam pumping units in an oil field, which has the advantages of shock absorption for the frequency conversion cabinet, easy replacement of filter elements, and combined use of air cooling and water cooling, and solves the problem that the current frequency conversion cabinet has a During the movement of the mobile inverter cabinet, due to the bumps on the road or the up and down slopes, the inverter cabinet is very easy to shake, causing damage to its internal electronic components. In addition, the existing inverter cabinet is cooling its interior Air-cooling is often used, but the air-cooling method is likely to cause dust accumulation on the filter element. After a long time of use, it will affect the heat dissipation effect of the inverter cabinet. At the same time, the cooling effect of air-cooling alone is poor, and it cannot guarantee the long-term heat dissipation of the inverter cabinet.
