Benefits of technology
The present patent provides a system for determining the work cycle of a fracking pump by using a pressure sensor to measure the pressure generated by the pump over a set period of time. This system analyzes the pressure signal to identify the boundary of the work cycle, determine the peak pressure, and determine the type of work cycle. This information can be used to improve the efficiency and reliability of the fracking process.
Problems solved by technology
The high discharge pressure, in turn may induce excessive stress on components of the fracking pump, such as one or more valves, seals, bearings, and so on.
Furthermore, different activities may induce varying levels of stress on the components of the fracking pump, in turn limiting use of the fracking pump for different activities.
For example, higher stress activities may limit an operation of the fracking pump for a limited number of hours before the fracking pump may be operated again for the same or a different activity.
Moreover, the fluid pumped by the fracking pump may be gritty and corrosive leading to early failure of the fracking pump.
The failure of the fracking pump may result in downtimes amounting to loss of time and money to the site operator.

Embodiment Construction
[0010]Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or the like parts. Referring to FIG. 1, a schematic representation of a work cycle determination system 10 for a fracking pump 12 is illustrated. The fracking pump 12 may be any pump known in the art, such as a positive displacement pump. The fracking pump 12 is associated with oil and gas industry and employed at a site (not shown) during a fracking process. The fracking process refers to a process of drilling down into the earth and directing high pressure fluid at a rock formation (not shown) to release trapped oil and / or gas which may be pumped to the ground level. In various embodiments, one or more fracking pumps may be combined to improve fluid flow and fluid pressure. The fracking process may also be referred to as a hydro-fracturing process, micro-hydraulic fracturing process or a hydro-fracking process.

A work cycle determination system for a fracking pump is provided. The work cycle determination system includes a pressure sensor adapted to generate a signal indicative of a pressure generated by the fracking pump, and a controller communicably coupled to the pressure sensor. The controller receives the signal indicative of the pressure generated by the fracking pump over a predefined period of time. The controller identifies a boundary of a work cycle within the predefined period of time by analyzing the signal. The controller also determines a peak pressure of the work cycle and a time duration of the work cycle. The controller further determines a type of the work cycle of the fracking pump based on the peak pressure and the time duration of the work cycle.
Description
TECHNICAL FIELD[0001]The present disclosure relates to a work cycle determination system for a pump. More particularly, the present disclosure relates to the work cycle determination system for a fracking pump used in oil and gas industry.BACKGROUND[0002]Generally, fracking pumps are employed during downhole activities in oil and gas industry. Such activities may include perforation and fracking for production of oil and / or gas from rock formations. In some situations, multiple fracking pumps may be used in tandem to perform perforation and fracking in a. cyclic manner or as per operational requirements. Further, multiple fracking pumps may be grouped together to improve fluid flow and fluid pressure. In such a situation, different groups of the fracking pumps may be assigned preset activities, such as either perforation or fracking, to be performed sequentially or as per operational requirements.[0003]The fracking pump includes an intake manifold at low pressure and a discharge man...
