Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic pressure, and in particular relates to an auxiliary tool for inspecting triangular grooves of a valve plate of a plunger pump. Background Art

[0002] When the hydraulic plunger pump moves at high pressure and high speed, the cylinder body will rotate with the operation of the shaft, because the distribution plate is fixed on the pump cover. As the cylinder body moves, the triangular groove oil suction area of ​​the distribution plate will transition from low-pressure oil to high-pressure oil, and the oil pressure area will transition from high-pressure oil to low-pressure oil. If the triangular groove of the distribution plate is not in the right position, noise and vibration will occur, which will cause serious wear of the distribution plate during operation. Therefore, the position of the triangular groove will affect the use of the distribution plate and the life of the plunger pump. The dimensional inspection of the triangular groove position of the distribution plate for single-piece small batches mainly relies on instruments; inspecting the triangular groove position in mass production will be time-consuming and labor-intensive, and may even affect production progress.
