Abstract

Abstract: In view of the characteristic of severe erosion and abrasion in the fracturing pump valve, CFD-based erosion and failure is simulated and computed. The distributed rule of the pump valve lift, times of stroke, the height of the seal and the sealing contact length at a certain moment are shown. By analyzing the characteristic of the flow field from the simulated result and the failure mechanism of the fracturing pump valve, it is concluded that the lift is smaller, the greater is the flow velocity, the high times of stroke will increase the flow rate and the lag height of the pump valve, when the valve of h1 becomes bigger, although the force of the valve disk shocking the seat is smaller, the velocity of the valve becomes even bigger and the area is reduced,when the valve of L becomes smaller, although the force of the valve disk shocking the seat is greater, the velocity of the valve becomes even smaller and the failure is reduced.

Key words: the fracturing pump, pump valve, erosion and failure, simulation and computation
