Abstract

The invention discloses an air cushion conveyor belt conveyor air film thickness test control device, which comprises n sensors, a PID (Proportion Integration Differentiation) controller, a data acquirer and an actuator, wherein n is larger than or equal to 1. An air cushion conveyor belt conveyor air film thickness test control method comprises the following steps of acquiring relevant data; comparing and analyzing data results and theoretical calculation results, and confirming the air film thickness and the air chamber static pressure suitable for an air chamber; adopting a PID control method, adopting the air film thickness as a controlled object, and controlling the power of a fan to adjust the air output of an orifice through the actuator so as to adjust the unreasonable air film thickness and air chamber static pressure. According to the air cushion conveyor belt conveyor air film thickness test control device and the air cushion conveyor belt conveyor air film thickness test control method, the accuracy of air film thickness test data is improved, the energy can be saved by adopting air film thickness control, and the power consumption of the air supply fan of the air chamber is reduced.

Description

【Technical field】 [0001] The invention relates to the field of mechanical transportation, in particular to a test control device and a test control method for the air film thickness of an air cushion conveyor belt conveyor. 【Background technique】 [0002] The air cushion conveyor has the advantages of stable and reliable operation, small running resistance, low energy consumption, large loading area, simple structure, low manufacturing and maintenance costs, low infrastructure costs, available belts for sealed transportation, and low dust pollution. [0003] The air film thickness is one of the main parameters of the air cushion conveyor. If the air film thickness is too large, it will inevitably lead to waste of energy consumption; The machine is not functioning normally. [0004] At present, at home and abroad, after the calculation of the air film thickness, only the verification test of the air film thickness is generally carried out to judge whether the disc groove is ...
