Fracturing apparatus

A fracturing apparatus, comprising:

• a plunger pump, comprising a hydraulic end and a power end, wherein the power end comprises a power end oil outlet and at least one power end oil inlet that are coupled to each other;
• a power end lubricating system, comprising:
• a lubricating oil tank defining an accommodation space, at least one lubrication pump having a lubrication pump oil inlet and a lubrication pump oil outlet that are coupled to each other, and at least one lubrication motor configured to provide power for the at least one lubrication pump, wherein the lubrication pump oil inlet is coupled to the accommodation space of the lubricating oil tank, the power end oil outlet is coupled to the accommodation space of the lubricating oil tank through an oil return pipeline, the lubrication pump oil outlet of the at least one lubrication pump is coupled to the at least one power end oil inlet through at least one oil inlet pipeline;
• a temperature detector disposed on any one of the oil return pipeline, the power end oil outlet, and the lubricating oil tank, and configured to detect a temperature of the lubricating oil flowing from the power end into the oil return pipeline;
• and
• a control system connected to the temperature detector and the power end lubricating system and configured to control the power end lubricating system,
• wherein the control system is configured to control the at least one lubrication motor to keep on operating when the plunger pump stops operating and the temperature detected by the temperature detector is greater than a first preset value.
