Improves the operational reliability of the fire hydrant pump to increase fire extinguishing speed
Install a bell in the pump room. Was added the corresponding control schematic fire alarm, bell and releasing the test function, in order to facilitate pumping station attendant in case of fire, the fire hydrant pump start promptly. Enhance the reliability of the fire hydrant pump, thereby improving the speed of fire, to reduce the pump for a time unnecessary losses due to delays from the fire hydrant pump control principle of FIG. Improvement is the author of After analysis and comparison, consider starting from the use of the system is stable, reliable, convenient angle. For different use places, there may be functional increase or decrease, and improved control principles.
The functional improvement of the schematic diagram of fire hydrant pump control is only the author's experience in engineering practice in recent years. At the same time, the users of several high-rise buildings have also been surveyed. Everyone agrees that: The working reliability of the secondary system of fire hydrant pumps must be To be given enough attention, its timely control of fire and fighting is more important than any other fire-fighting facilities, and its use is done by people (especially starting, fire extinguishing, etc.). Therefore, its control system should be as much as possible. It is convenient, fast and reliable to achieve. When a fire occurs, the timely development and spread quickly controlled the fire, serve the purpose of the loss is reduced to a minimum.
Machine for Filament
Height of machine is suitable and easy operation.
Filament fiber spindle with special processing and with wider suitable range.
Simple driving system and easy for maintenance.
Winding bobbin can be suiable with tube type, electric forming with servo traverse, PLC program control electric anti-overlap exactly, avoid yarn overlap,increase the unwinding efficiency of after production efficiency.
Innovative electric driving system,protection system can keep machine with same processing after power off suddenly.
