Problems solved by technology

[0003] However, in the prior art, precision hydraulic control components such as load-sensitive pumps and proportional valves are used. When there are impurities in the hydraulic oil, it is easy to cause failures such as inaccurate control and control failure; a set of pumping stations supplies the driving power of each hydraulic cylinder , one of the hydraulic cylinder branch systems fails, and the entire system must be stopped for maintenance, which is easy to damage the continuity of production. At the same time, this one-pump multi-cylinder control method is easy to produce high-pressure shocks when the stroke switch is reversing, causing the oil pipes to burst. , component damage

Abstract

The invention relates to the technical field of cement production, and particularly relates to a servo hydraulic drive control system of a grate cooler and a data processing method of the servo hydraulic drive control system. The servo hydraulic drive control system comprises an industrial personal computer and hydraulic drive modules, wherein tach hydraulic drive module comprises a hydraulic cylinder, a reversing unit, a servo motor, a gear metering pump and a driver; and the driver is connected with the servo motor, the servo motor drives the gear metering pump, the outlet of the gear metering pump is connected with the reversing unit, the reversing unit is connected with the hydraulic cylinder, and an electronic ruler is arranged on the hydraulic cylinder. The industrial personal computer can be connected with the multiple hydraulic drive modules. The servo hydraulic drive control system is sensitive in control response, fast in response, small in impact force during reversing and capable of achieving multi-cylinder synchronous control.

Description

technical field [0001] The invention relates to the technical field of cement production, specifically a servo hydraulic drive control system for grate coolers. Background technique [0002] In the existing cement production field at home and abroad, the grate cooler is responsible for the uninterrupted transportation and cooling of clinker. At present, the movable grate plate of the grate bed of the grate cooler adopts the "electro-hydraulic action control system", and its hydraulic drive system Realize execution through complex hardware architectures such as hydraulic pumps, proportional valves, reversing valves, pipelines, and hydraulic cylinders. [0003] However, in the prior art, precision hydraulic control components such as load-sensitive pumps and proportional valves are used. When there are impurities in the hydraulic oil, it is easy to cause failures such as inaccurate control and control failure; a set of pumping stations supplies the driving power of each hydrau...
