Description

Technical Field

[0001] The invention relates to the technical field of oilfield mechanical oil production equipment, in particular to a variable frequency heat dissipation device and system for a semi-direct drive control box. Background Art

[0002] The energy transmission method of conventional oil pumps is belt drive. The adjustment of the pumping frequency is mainly to adjust the motor pulley. The disadvantage of the belt transmission method is that the energy has friction loss, the belt life is greatly affected by external factors, and the belt replacement is time-consuming and labor-intensive, which poses certain safety hazards. The energy transmission method of semi-direct drive oil pumps is that the motor directly drives the transmission shaft of the reduction box, without energy loss. The adjustment of the stroke frequency mainly relies on the control box to adjust the motor speed by frequency conversion. In order to prevent rain and dust, the control box is a relatively closed space. The heat radiation generated by various electrical components, especially the heat radiation generated by the inverter, is relatively large. In this closed space, heat accumulates for a long time, causing the temperature inside the box to be very high, exceeding the maximum operating temperature of the inverter by 50℃, and the protection stops working.

[0003] At present, the inverter cooling device of the control box uses two upper fans to reduce the inverter temperature. When the ambient temperature is high in summer, the heat in the control box is dissipated slowly, and the internal temperature is very high, which seriously causes the internal components to melt and burn. The inverter also often shuts down due to high temperature, which seriously affects the normal production of the oil pump. An efficient cooling device is needed to solve the problem of frequent shutdown of the inverter due to high temperature. Therefore, it is necessary to develop a inverter cooling device for a semi-direct drive control box. Summary of the invention

At the same time, the output end of the motor is selected to achieve rotary pumping, so that the first connecting shaft drives the support frame to move up and down, thereby driving the filter plate to be cleaned, thereby further preventing dust and achieving further heat dissipation. Heat is mainly dissipated through the principle of heat convection. Exhaust plates are added on both sides of the lower part of the control cabinet to quickly dissipate the heat in the box, reduce the temperature in the box, improve the temperature stability of the inverter, increase the service life of the inverter, increase the production time of the oil pump, and better guarantee crude oil production.

[0017] 2.

[0018] 3.
