Problems solved by technology

For example, in the case of a fluid spraying device having a plurality of spray control systems, if each spray control system performs high-precision water pressure control at a pressure of about 0.5 MPa, the cost in terms of manufacturing or operation increases.
On the other hand, when high-precision water pressure control is performed on the common water supplied to multiple spray control systems, the properties of the mist cannot be controlled for each spray control system

Abstract

A two fluid spray device (10D) is provided with: a two fluid nozzle (1a) for a plurality of systems for mixing pressurized water and compressed gas and spraying same; water supply equipment (3) for supplying pressurized water having common water pressure to the two fluid nozzle (1a) for the plurality of systems; compressed air supplying equipment (4) for supplying compressed air having common airpressure to the two fluid nozzle (1a) for the plurality of systems; and a plurality of spray control units (2a, 2b) for controlling spray of the two fluid nozzle (1a) for each of the plurality of systems. Each of the plurality of spray control units (2a, 2b) is provided with a water pressure control unit (25a) for pressure reducing control of the water pressure of the pressurized water supplied bythe water supply equipment (3) on the basis of a spray command value without pressurization and an air pressure control unit (22aD1, 22aD2) for controlling the pressure of the compressed air suppliedby the compressed air supply equipment (4) on the basis of the spray command value.

Description

technical field [0001] The invention relates to a two-fluid spray device. Background technique [0002] Generally, there is disclosed a two-fluid spray device that supplies compressed gas and pressurized liquid to a two-fluid nozzle for spraying. [0003] For example, there is disclosed a two-fluid spray device that uses compressed gas from the compressed gas supply system to make the supply liquid from the liquid supply system to be higher than that supplied by the pressurized liquid when the remaining amount of pressurized liquid in the pressurized liquid supply system is insufficient. The pressurized liquid in the system is supplied to the pressurized liquid supply system at a high pressure, and spraying is continuously performed while keeping the supply pressure of the pressurized liquid in the pressurized liquid supply system constant (see Patent Document 1). [0004] In addition, there is disclosed a two-fluid spray device configured to be able to apply the pressure o...
