Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the examples and specific implementation methods, but this should not be interpreted as the scope of the above-mentioned subject of the present invention being limited to the following examples, and all technologies realized based on the content of the present invention belong to the present invention protected range.

[0021] Such as figure 1 with figure 2 As shown, the present invention is made up of shunt pipe 1, inlet pipe 2 and discharge pipe 3, and the diameter of the liquid inlet end of shunt pipe 1 is greater than the diameter of liquid outflow end, and inlet pipe 2 is tangent to shunt pipe 1, and discharge pipe 3 and shunt pipe 1 also Tangent, the place where the inlet pipe 2 and the outlet pipe 3 are tangent to the shunt pipe 1 coincides. In other embodiments, the inlet pipe 2 and the outlet pipe 3 can also be approximately tangent to the shunt pipe, and the place where they ...

Abstract

The invention relates to the technical field of petroleum and natural gas drilling, in particular to a suction pipe applicable to a fracturing pump. The suction pipe comprises a flow division pipe, a feeding pipe and a drainage pipe. The diameter of the liquid feeding end is larger than that of the liquid drainage end of the flow division pipe. The feeding pipe is tangent or approximately tangent to the flow division pipe. The drainage pipe is also tangent or approximately tangent to the flow division pipe. The part, connected with the flow division pipe, of the feeding pipe coincides with the part, connected with the flow division pipe, of the drainage pipe. In the structure, large and small heads are adopted for the flow division pipe for flow division, so that the flow and pressure of a front drainage outlet and a rear drainage outlet are more balanced. Both the feeding pipe and the drainage pipe are tangent to the flow division pipe, so that liquid forms a vortex in the flow division pipe to smoothly enter the drainage pipe so as to be beneficial to carrying sand, liquid drainage is smoother, and the suction volume rate is improved.

Description

technical field [0001] The invention relates to the technical field of oil and natural gas drilling equipment, in particular to a suction pipe suitable for a fracturing pump. Background technique [0002] The suction pipe of the fracturing pump mainly plays the role of diversion. The liquid (usually with sand and pressure) pumped in from a distance is diverted to the liquid cylinder (usually three or five cylinders) by the discharge steel pipe. The traditional suction pipe All intersecting steel pipes are connected to the center line, and irregular turbulent flow will be generated when the liquid flows into the steel pipes, which will easily cause defects such as sand accumulation, poor circulation, large pressure fluctuations, and unbalanced suction pressure of each cylinder. [0003] In order to solve the above problems, it is necessary to invent a fracturing pump suction pipe to solve problems such as sand accumulation, poor circulation, large pressure fluctuations, and u...
