Abstract

The invention discloses a power device of a fracturing truck. The power device comprises a base. The base is provided with a speed reducer and a fracturing pump support. The output end of the speed reducer is connected with a coupler. A fracturing pump is arranged on the fracturing pump support. The output end of the coupler is connected with the fracturing pump. The base is further provided with a supporting frame. The supporting frame is provided with a gas turbine and a starter motor starting the gas turbine. The gas turbine is connected with the output end of the starter motor. Power output by the gas turbine is transmitted through the speed reducer so as to drive the fracturing pump to work. Due to the fact that compared with a diesel engine, the gas turbine has the beneficial effects of being high in starting speed, low in weight, small in occupied space, large in power and adjustable in rotating speed, compared with an existing fracturing truck power device with the diesel engine as power, the power device of the fracturing truck is high in starting speed, low in weight, convenient to convey and small in occupied space during installation, meanwhile, power is large during work, the requirement of actual production can be met, and the rotating speed can be adjusted so as to meet the requirement for output of different values of power.

Description

technical field [0001] The invention relates to the field of oil and gas fracturing devices, in particular to a power device for a fracturing vehicle. Background technique [0002] The power plant of a traditional fracturing vehicle consists of a diesel engine, a hydraulic torque converter, and a fracturing pump. my country's proven natural gas reserves in shale geology are 26 trillion standard cubic meters, and the reserves of unexploited coalbed methane shale layers are 50 trillion standard cubic meters, and the annual mining volume is less than 5 billion standard cubic meters. At present, the water output power of the fracturing truck is about 3000hp. Due to the large domestic shale gas reserves and demand, the existing fracturing trucks are difficult to meet the fracturing requirements. must do. Contents of the invention [0003] The invention provides a fracturing vehicle power device to solve the technical problem that the existing fracturing vehicle power device p...
