Fracturing device and its moment load machine and measurement method of output power

Abstract

The invention discloses a fracturing device, a torque load machine and an output power measurement method thereof. The torque load machine comprises a brake disc and a brake device, wherein the brakedisc is arranged on an output shaft of the fracturing device, and the brake device is used for exerting braking force on the brake disc; the brake device comprises at least one pair of brake cooling fins which are oppositely arranged on two sides of the axial direction of the brake disc, brake rods of the brake cooling fins are relatively close to or far away from one another under the action of the oil pressure of the brake oil cavity; and the torque load machine further comprises an oil pressure control system used for adjusting the oil pressure of the brake oil cavity and a heat dissipationcooling system used for cooling the friction heat between the brake device and the brake disc. The torque load machine is simple in structure and low in cost, extra load consuming equipment does notneed to be configured, and the friction heat can be consumed only by introducing cooling water; and the braking device is controlled by the oil pressure control system to apply braking torque to the brake disc, and the power adjustment is simple, so that the torque load machine can meet the braking torque adjusting requirements of different working conditions.

Description

technical field

[0001] The invention relates to the field of fracturing devices, in particular to a moment load machine for fracturing devices. In addition, the present invention also relates to a fracturing device including the above-mentioned moment load machine and a method for measuring the output power of the fracturing device. Background technique

[0002] At present, the domestic professional production of moment load machines for gas turbine fracturing devices is almost zero, while power machines are mostly used in the market. The configuration of power machines is more complicated and the cost is higher. The power of more than 100kW is at least 1 million. . The power machine is generally composed of a dynamometer (or torque meter) and a load machine. The function of the load machine is to consume the power of the system. There are water power load machines, power generation load machines, etc. The water power load machine is used to make boiling pools. At the same...
