Abstract

The invention discloses a speed protection controller for a belt type oil pumping unit. The speed protection controller comprises a mounting frame, wherein a reduction gearbox is mounted on the side edge of the mounting frame; an electric appliance fixing frame is mounted at the bottom end of the interior of the mounting frame; a clamping frame is mounted in the middle of the inner side of the mounting frame; a circuit box and a heat dissipation component are mounted on the inner side of the clamping frame; the heat dissipation component is positioned above the circuit box; a mounting box is mounted at the position, close to the top, of the inner side of the mounting frame; a PLC is arranged on the inner side of the mounting box; the heat dissipation component comprises a plurality of setsof transversely-arranged clamping blocks; a clamping plate is arranged between every two adjacent clamping blocks; and inserting rods are arranged on the side walls penetrating through the clamping blocks and the clamping plates. According to the speed protection controller, the PLC can be effectively protected, the PLC is prevented from being damaged during use, and a velometer, a frequency converter, a driving power supply and an overload switch are convenient to mount and maintain; and meanwhile, a good heat dissipation effect is achieved, and the controller is prevented from being influenced by high temperature.

Description

technical field

[0001] The invention relates to the field of controllers, in particular to a speed protection controller for a belt pumping unit. Background technique

[0002] The belt pumping unit drives the belt through the motor to drive the relevant structure of the pumping unit to achieve the pumping speed. The speed of the motor determines the speed of the pumping unit. In order to avoid excessive To work, it is necessary to use the speed protection controller to control the speed of the motor, so that the speed of the motor is in the normal operating range, so as to realize the protection of the pumping unit.

[0003] There are certain disadvantages in the existing speed protection controller for belt pumping units in use. The existing speed protection controller for belt pumping units is not convenient enough to install the heat dissipation structure, and the heat dissipation structure cannot Realize synchronous heat dissipation from top to bottom; when the existing...
