Indoor high pressure fire water supply system saves the fire hydrant box remote start button and alarm valve group pressure switch, reducing the number of human factors, as long as the usual strengthening of the fire equipment maintenance, inspection and management, can improve the efficiency of fire equipment. In addition,

"Civil water fire extinguishing system design rules" provides that: 1, the system should be located fire pump. Fire regulator pump, fire tank should be set with the fire pump in the same fire pump room;

Chiller may occur in a variety of different types of failure, why the pump flow rate is too large or too small fault?

Our company now has sophisticated technology equipment, top detection equipment, perfect supporting facilities, further improving the product quality.

First, change the frequency of power, that is, using the inverter. The advantage of using the frequency converter is to provide a closed-loop control of the vacuum pump, but in large loads easily lead to the loss of torque.

Made of independent diesel engines, fire pumps and fire cannons, and with fire hose, quick connectors, valves and other vehicle fire safety equipment.

The ultimate in tailor made fire protection pump packages are the SPP Pumps pump house packages, housing pumps, control systems and pipework. After simply connecting the water and power supplies on site, the unit is immediately operational.
