Embodiment Construction

[0017] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] Combine below figure 1 and figure 2 , the preferred embodiment of the present invention will be further described in detail, and an electric fracturing skid in this preferred embodiment is taken as an example:

[0019] like figure 1 As shown, an electric fracturing skid includes a skid plate 1 and a fracturing pump transmission system. The fracturing pump drive system includes a motor 2, a front drive shaft 3, a gearbox 4, a rear drive shaft 5, and a fracturing pump 6. The motor 2 is connected to the front drive shaft 3, and the front drive shaft 3 is connected to the input shaft of the gearbox 4. The main output shaft of the gearbox 4 is connected with the rear transmission shaft 5 ,...

Abstract

The invention discloses a fracturing pump transmission system. The fracturing pump transmission system comprises a motor, a front transmission shaft, a gearbox, a rear transmission shaft and a fracturing pump, wherein the motor is connected with the front transmission shaft; the front transmission shaft is connected with an input shaft of the gearbox; a main output shaft of the gearbox is connected with the rear transmission shaft; and the rear transmission shaft is connected with the fracturing pump. The invention further provides an electric fracturing pry. According to the fracturing pump transmission system and the electric fracturing pry disclosed by the invention, the motor and the gearbox are combined, thus changing the traditional speed regulation principle of a motor and a frequency converter, and improving transmission stability, safety performance and transmission efficiency; and compared with a diesel engine, the fracturing pump transmission system and the electric fracturing pry are non-spark, and low in vibration and noise during working.

Description

technical field [0001] The invention relates to the field of oil and gas field fracturing equipment, in particular to a fracturing pump transmission system and an electric fracturing skid. Background technique [0002] With the in-depth development of shale oil and shale gas mining and the wide application of hydraulic fracturing technology, oil and gas fields have put forward higher requirements for fracturing equipment. Press trucks and fracturing skids emit a large amount of exhaust gas during work. The exhaust gas contains not only greenhouse gas carbon dioxide, but also sulfur dioxide and nitrogen oxides. These gases seriously pollute the environment. When the diesel engine is working, sparks may be emitted from the exhaust gas, posing a fire hazard to oil and gas field production. [0003] In order to solve the above problems, electric motors are used to drive. At present, electric fracturing skids use frequency converters to regulate the speed of electric motors. Du...
