An overview of the
The series of control box (cabinet) is designed for building fire pump equipment and design and development of products,. With overload, over-current protection function, etc. On the cabinet put oneself in another's position is equipped with power supply, operation, failure and other instructions, so a clear understanding of the motor and so on all sorts of equipment running status. Panel also has start, stop and manual/automatic switch button.
Fire pump control cabinet, generally there are two ways to control fire hydrant control (X) and spray control (P). For fire hydrant control, the company according to the fire hydrant button series connection, namely the meet fire hydrant normally open point (as a result of which can be normally closed conduction state) after a series of two feet line access control cabinet. Pressure controller was designed for the spray control cabinet: the company normally open contacts, when caused by pressure differential pressure relay action, control circuit to make winner loop action, start the spray pump. Whether fire hydrant control or spray control, control cabinet are configured with the center of the fire contact signals, including operation, stop, fault signal, also provides the DC24V relay, provide/stop using the fire control center.
Functional features
The control cabinet is set to the dual one, one with a case and so on. A fire pump running another fire pump standby starting control device. When running after the fire pump downtime, the standby fire pump automatically put into operation, ensure reliable supply of fire pump.
Working status: this series of two electric control cabinet is equipped with manual/automatic control state. Manual control state is on the front panel for on-site operation. Automatic control state is controlled by pressure controller point pump is working. Only when the control pressure controller provides a signal, the system can work normally.
Start the way; According to the practical can be used directly soft starter launched a variety of ways, and have reduce the starting current impact on power grid. Reduce the pump starter drive torque, reliable and fast start of motor. Reduce the motor and pump failure rate, prolong the service life of motor and pump. Has the motor function of soft parking, eliminate water hammer pump when the pump is stopped, is an ideal product to fire pump control
