During the operation of the fracturing pump, the friction between the sliding shoe and the guiding plate generates heat, which can rise the temperature of the friction surface, causing the fracturing pump to fail. Generally, relying only on worker experience to adjust the gap between the guiding plate and the sliding shoe and determine the oil supply flow lacks scientific basis and theoretical guidance, which may result in sliding shoe and guiding plate wear, and the increasing probability of burning tile. It seriously shortens the service life of the fracturing pump and affects the safe production of fracturing operations. Therefore, this paper studies the frictional heat generation and heat dissipation mechanism of the sliding shoe and guiding plate. After deriving the formula, a model for the influence of the gap of the sliding shoe and the guiding plate and the oil supply flow rate on the temperature rising of lubricating oil is established. And the test validation was carried out on the experimental platform of 6000 HP fracturing pump. The results showed that the change of temperature rise of the lubricating oil is more obvious as the gap decreases. When the gap between the sliding shoe and the guiding plate is less than 0.2 mm, the temperature of the lubricating oil reaches 360 K, which has exceeded the allowable working temperature of the selected lubricating oil. An increase in the flow rate of the lubricating oil can lower the temperature of the lubricating oil; however, when the flow rate of the lubricating oil exceeds 2 L/min, the effect on the temperature rise of the lubricating oil is not significant. In this study, a lubrication cooling state model for fracturing pump calibration was proposed. It provides a theoretical basis and design reference for reasonable selection of lubricating oil supply flow and the gap.
