High-power five-cylinder plunger pump

Abstract

The invention discloses a high-power five-cylinder plunger pump. The stroke of the high-power five-cylinder plunger pump is 10 in, the cylinder spacing is 11.5 in, and the braking power is 5000 HP. The plunger pump has the beneficial effects that the power is large, and the displacement is large; the pump is suitable for electric drive fracturing and turbine fracturing; the integral power end assembly or the split type power end assembly can be selected according to specific operation working conditions, so that the arrangement mode of a fracturing unit or a fracturing vehicle is better realized; and the stable operation with the long stroke and the braking power of 5000 HP is guaranteed by means of the size of the cylinder spacing.

Description

technical field [0001] The invention relates to the technical field of plunger pumps, in particular to a high-power five-cylinder plunger pump. Background technique [0002] With the continuous development of ultra-high pressure, ultra-deep wells, and horizontal wells in oil and gas fields, their operating conditions are getting worse and worse. It is required that fracturing equipment can operate at high pressure and large displacement. Some well sites also require long-term continuous operation. When the total pressure of the well site is constant, the smaller the power displacement of a single fracturing equipment, the more fracturing equipment is required to meet the total pressure demand of the well site. [0003] At present, the well site occupied by oil and gas production is required to be smaller and smaller, and reducing the number of fracturing equipment is one of the effective means; the actual well site access is also more rugged, and the more fracturing equipmen...

Problems solved by technology

[0005] In addition, turbo fracturing is also the development trend of fracturing operations in the near future (turbo fracturing is a fracturing operation that uses a turbine engine as a power source), but the output rotation direction of the turbine engine cannot match the input rotation direction of the existing plunger pump , so usually a reversing mechanism is added before the plunger pump inputs the rotation direction, but this will bring about an increase in the overall weight of the turbo fracturing equipment, an increase in the risk of failure, and an increase in maintenance costs, etc.
