Abstract

The invention relates to a plunger pump crankshaft grinding device and an application method, belongs to a plunger pump maintenance technology, and solves the problems in the prior art. The plunger pump crankshaft grinding device comprises a base, a driving motor, a transmission belt wheel, an abrasive paper wheel, a transmission belt and bolts, wherein the driving motor is fixed on the base; thetransmission belt wheel is mounted on the driving motor, and the transmission belt wheel is connected with the abrasive paper wheel by the transmission belt; the base is fixed on a crankshaft balanceblock by two bolts; the two bolts are connected to the outer side of the base, and are adjustable; the abrasive paper wheel comprises two 180-degree semicircular tiles; two pieces of abrasive paper are respectively mounted between the two semicircular tiles; and two edges of the abrasive paper are clamped by joint ports of the two semicircular tiles to fix the abrasive paper.

Description

technical field [0001] The invention relates to a plunger pump maintenance technology, in particular to a plunger pump crankshaft grinding device and an application method. Background technique [0002] During the oil field water injection process, due to the relatively high water injection pressure in the oil field, the water injection equipment is prone to accidents such as the crankshaft of the plunger pump, the burning of the tile, and the pulling of the cylinder. During the maintenance process of the plunger pump, the burnt and strained crankshaft needs to be polished. Since there is no professional grinding machine for crankshafts, it is necessary to rely on manual grinding. Manual grinding is not only inefficient, but also wastes manpower, which seriously affects the maintenance work of plunger pumps. Contents of the invention [0003] The purpose of the invention is to provide a plunger pump crankshaft grinding device and application method for automatically grind...
