Wood material board hot-pressing device and operation process for such a device |
摘要 |
A wood material board hot-pressing system with a primary circuit includes a supply pipe for discharging of hot heat transfer fluid from a heat generator and a return pipe for supplying cooled heat transfer fluid to the heat generator. A secondary circuit features a pressing device for pressing wood material boards. A supply channel supplies heat transfer fluid to the pressing device and a return channel returns cooled heat transfer fluid to the primary circuit. A controlling device contains a control valve and is configured to control a flow of heat transfer fluid from the primary circuit to the secondary circuit. A secondary circulation pump with variable output is set up to circulate the heat transfer fluid in the secondary circuit. The controlling device features a heat output recording device and is configured to automatically control a level of heat output (P) supplied to the pressing device. |

1. A wood material board hot-pressing device, comprising:
a primary circuit, which comprises:
a supply pipe which discharges hot heat transfer fluid from a heat generator; anda return pipe which supplies cooled heat transfer fluid to the heat generator; a secondary circuit, which comprises:
a pressing device which presses wood material boards;a supply channel which supplies heat transfer fluid to the pressing device; anda return channel which returns the cooled heat transfer fluid to the primary circuit; and a controlling device, which comprises:
a control valve; andis set up to regulate a flow of the heat transfer fluid from the primary circuit to the secondary circuit; and a variable output secondary circulation pump, which is set up to circulate the heat transfer fluid in the secondary circuit, wherein the controlling device comprises:
a heat output recording device; andis configured to automatically regulate a level of heat output to be supplied to the pressing, wherein the controlling device is programmed to automatically increase a target primary pressure difference, if the control valve is in a maximum position and heat output is to be increased. |
