Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem in the prior art that the size of the gap and the thickness of the oil film in the gap cannot be known when adjusting the end face gap, so it is impossible to accurately predict the amount of leakage and wear according to the thickness of the oil film, and to provide an adjustable end face gap The intelligent gear pump can measure the thickness of the end clearance oil film online in real time, and adjust the axial distance between the gear and the sliding bearing shaft by changing the thickness of the piezoelectric ceramic gasket to achieve the compensation purpose of the end clearance, so as to realize the accuracy of the end clearance and oil film thickness control

Abstract

The invention discloses an intelligent gear pump with adjustable end face clearance, belonging to the technical field of gear pumps; comprising a pump body device and an intelligent control system. It is composed of a driving shaft, a driving wheel, a driven wheel and a sliding bearing. The intelligent control system is composed of an ultrasonic probe and a piezoelectric ceramic gasket connected to a data processing control device through a control circuit; the ultrasonic probe is connected inside the sliding bearing. The sliding bearing is connected to the front end cover and the rear end cover through the piezoelectric ceramic gasket, and the ultrasonic probe is connected to the external data processing control device through a control circuit and is controlled by the data processing. The device is connected to the piezoelectric ceramic spacer. The invention adopts the combination of the pump body device and the intelligent control system, and adjusts the axial distance between the gear and the sliding bearing shaft by changing the thickness of the piezoelectric ceramic gasket, thereby realizing the precise regulation of the end face clearance and the thickness of the oil film.

Description

technical field [0001] The invention relates to a gear pump, in particular to an intelligent gear pump with adjustable end face clearance, belonging to the technical field of gear pumps. Background technique [0002] Gear pumps are applicable to a wide range of industries and have a wide range of conveying media, playing an important role in many chemical and industrial fields. And it has the advantages of firm structure, convenient installation, easy disassembly and so on. [0003] In the operation of the gear pump, the leakage between the bearing and the end face of the gear accounts for more than 75% of the total leakage. The leakage will cause the volumetric efficiency of the gear pump to decrease and reduce the service performance of the entire gear pump. The main reason for end face leakage is due to the existence of end face clearance. If the end face clearance is too small, the wear of gears and bearings will be aggravated; and if the end face clearance is too large...
