Technical Field

[0001] The utility model relates to the field of wear detection devices, in particular to a wear detection device for an oil distribution plate of a plunger pump. Background Art

[0002] The oil distribution plate plays a key role in sealing and distributing oil in the plunger pump. A severely worn oil distribution plate may cause leakage, affect the working efficiency and performance of the plunger pump, and may even cause pump failure. Regularly checking the degree of wear of the oil distribution plate can detect problems in time and repair or replace it, thereby extending the service life of the plunger pump and reducing production downtime and maintenance costs caused by pump failure.

[0003] Usually, when conducting inspection, it is necessary to first fix the oil distribution plate on the device, and then use a micrometer or other precision measuring tools to measure the key dimensions of the oil distribution plate, such as diameter, flatness, depth of the oil groove, etc., to evaluate whether the oil distribution plate has reached or is close to the maximum wear limit.

[0004] However, considering that during measurement, hard debris such as iron filings on the surface of the oil distribution plate may not be discovered and removed in time, friction or damage may occur between the oil distribution plate and the measuring equipment, which will not only affect the accuracy of the measurement, but also cause damage to the equipment itself, increasing the cost of maintenance and replacement.
