Abstract

The invention discloses a hydraulic motor sealing performance detection device. A workpiece conveying device is longitudinally arranged on a base, a detection station for detecting sealing performance of a hydraulic motor is arranged on the workpiece conveying device, the position of the detection station is kept fixed relative to the base, a sealing device comprises a transverse sealing device used for sealing a side hole of the hydraulic motor and a top sealing device used for sealing a top through hole of the hydraulic motor, and the transverse sealing device, an air tightness detection device and the top sealing device are sequentially arranged in the height direction of the workpiece conveying device from top to bottom. The transverse sealing device and the air tightness detection device are used for sealing or detecting the hydraulic motor on the detection station through a moving device, and the top sealing device is used for sealing the hydraulic motor on the detection station through a longitudinal moving device. The position of a plugging head is adjusted by adjusting the motor up and down, and airtightness detection can be carried out on hydraulic motors of different models.

Description

technical field [0001] The invention relates to a hydraulic motor detection device, in particular to a hydraulic motor sealing performance detection device. Background technique [0002] The hydraulic motor is an actuator of the hydraulic system, which converts the hydraulic pressure energy provided by the hydraulic pump into the mechanical energy of its output shaft. Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, construction machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical, port machinery, etc. Hydraulic motors can be divided into gear type, vane type, plunger type and other types according to their structure types. According to the rated speed of the hydraulic motor, it is divided into two categories: high speed and low speed. The rated speed higher than 500r / min belongs to the high-speed hydraulic motor, and the rated speed lower...
