Method for suppressing zero drift by debugging amplification plate of radial plunger pump

Abstract

The invention discloses a radial plunger pump amplification plate debugging zero drift suppression method, which comprises the following steps: analyzing the display condition of a display lamp on a panel of an amplification plate of a main pump, and determining an alarm fault reason; the servo valve of the main pump and the mechanical zero point position of the main pump are detected through port communication of the amplification plate; and comparing the measurement data with the standard zero data, calculating a deviation value between the detection data and the standard zero data, and performing zero deviation correction according to the deviation value. By correcting the mechanical zero position and the electrical zero position of the equipment, zero position drift of the mechanical zero position and the electrical zero position is solved, the accurate corresponding relation between the mechanical zero position and the electrical zero position is recovered and kept, and accurate control over the main pump is achieved.

Description

technical field [0001] The invention belongs to the technical field of electro-hydraulic precise control of heavy industry forging equipment, and in particular relates to a method for debugging and suppressing zero-position drift of an amplifying plate of a radial piston pump. Background technique [0002] In the actual production process, the precise cooperation between the mechanical system and the electrical system of the equipment is an important factor to ensure that the equipment produces high-quality products, and it is also the basic guarantee that all the functions of the equipment meet the standards. [0003] The 3,000-ton hydraulic press currently used in the special steel workshop was built and used by the German PANK company in 2003. Eight main pumps (750 radial piston pumps) have always been the fundamental guarantee for the normal and fast operation of the hydraulic press. However, during long-term use, due to mechanical Structural wear and electrical control ...
