Fixed foam extinguishing system Price parameters Service conditions of pressure type proportioning device

Description :

　　The pressure type proportional mixing device produced by Shandong Dongyue Crane and Fire Equipment Manufacturing Co., Ltd. is divided into membrane type and ordinary type according to the filling method; According to the placement method of the tank, it can be divided into two forms: horizontal and vertical. The mixing ratio of foam is generally 3% or 6%, and 8% mixed liquid can also be provided for medium expansion foam fire extinguishing system. The mixed liquid flow rate of the device is 4-80L/S, and the storage tank capacity is 1000-10000L with different specifications. According to the required mixed liquid flow and foam injection time, the proportional mixer and foam tank can be arbitrarily combined into a series of products to meet the needs of engineering applications.

　　The usage conditions of pressure type proportional mixing device:

　　1. The pressure of the fire pump matched with the mixing device must meet the requirements of the inlet working pressure of the mixer.

　　2. The working pressure range of the device is 0.6~1.2MPa, which cannot be used beyond the specified range of use, otherwise the mixing ratio will be affected and the quality of foam will be reduced.

　　3. The pressure used by the mixing device within the calibrated working pressure range depends on the working pressure of the matched foam extinguishing equipment and the magic resistance loss of the equivalent length of the pipeline.

　　4. In standby mode, all valves in the mixture should be closed.
