Problems solved by technology

[0003] It is a very effective way to spray deicing fluid by spraying vehicle for anti-icing and deicing, but it is required that the flow of deicing fluid sprayed should be stable and evenly sprayed, because any extremely small pavement is not sprayed or sprayed If it is not enough and freezes, it may cause a safety hazard to the take-off and landing of the aircraft.

Embodiment 1

[0040] Embodiment 1: When the present invention is working, the speed sensor is used to collect the running speed of the sprinkler and upload it to the PID control module, click the spray density setting knob on the rotary operation panel, and set the target spray density (

[0041] Deicing agent 20ml / m 2 ~50ml / m 2 ; or, water 100ml / m 2 ~300ml / m 2 ;

[0042] ), and according to the spreading and retracting state of the spraying arms on both sides of the distribution vehicle, determine the spraying width mode of 3.2m or 9.35m or 15m. The demand value of the ice pump or water pump flow, through the difference between the demand value and the actual value of the deicing pump or water pump flow, is used as the input of the deviation PID control module, and the proportional output signal of the PID control module is applied to the hydraulic pump flow ratio Valve, so as to change the speed of the drive motor of the deicing pump or water pump, change the flow rate of the deicing ...

Abstract

The invention relates to a distributor spraying flow control system, and belongs to the field of aviation ground equipment. One key technical parameter of a distributor is to ensure that the spraying volume of deicing fluid per unit area is constant. Through the establishment of mathematical function relationship between the spraying volume of fluid per unit area on one hand and the vehicle speed, the flow of a spray pump and the displacement of a hydraulic pump on the other hand, a control system with the flow of the spray pump as a control objective is formed. The required flow is calculated according to the vehicle speed, the spraying density and the spraying width. The actual flow is detected through an electromagnetic flow meter. After comparison between the actual value and the required value, the displacement of the hydraulic pump is adjusted for the second time, and spraying is carried out again, in order to realize precise control on the flow.

Description

technical field [0001] The invention relates to the field of flow spraying equipment, in particular to a spraying flow control system of a distributor. Background technique [0002] As we all know, icing on the airport pavement will cause the aircraft to be unable to take off and land. If the ice layer is too thick, it will be very difficult to clean up. Therefore, anti-icing and deicing work on the airport pavement is an important guarantee task. [0003] It is a very effective way to spray deicing fluid for anti-icing and deicing by spraying trucks, but it is required that the flow of deicing fluid sprayed should be stable and evenly sprayed, because any extremely small pavement is not sprayed or sprayed. If it is not enough and freezes, it may cause a safety hazard to the take-off and landing of the aircraft. At the same time, due to the high price of deicing fluid, new requirements are put forward for the spraying of deicing fluid, which not only must meet the requireme...
