QLC(Y QLC(Y series emergency fire fighting water supply equipment Mainly for the initial fire fighting water supply of 0- minutes for buildings, used as a high-positioned water tank for the places no way to set it and for such temporary buildings as available with fire fighting demand. Executed standard GA0. Fire fighting pneumatic water supply equipment About the product QLC(Y series fire fighting boosting & pressure stabilizing equipment consists of a water-supplementing pump, a pneumatic tank, an electric control cabinet, necessary valves, pipelines etc. Attachments. Usually two water pumps of an identical performance are set, with one used and one standby, and automatically work alternatively. In case of a failure with one of them, the other is put into use. The pneumatic tank, as the necessary link for the pressure keeping at the equipment stop, supplies water to and maintains the pressure for the fire fighting pipe-net, acts as a pressure switch and supplies 0-min water for the fire fighting system. The electric control cabinet is used to control starting/stopping the pump, realizing the automatic running control of the equipment.

When the pressure stabilizing pump works, it feeds water into the pipenet and, when the surplus water goes into the pneumatic tank, the water room gets expanded, the air-room gets shortened and the pressure gets raised. When the pressure of the pipe-net rises to the upper limit of the pressure stabilization, the water-supplementing pump stops working to enter the stopped and pressure-kept status and the stored water is fed into the pipe-net by the pressure of the compressed air inside of the pneumatic tank, then the water room gets shortened, the air room gets expanded and the pressure falls down therewith. When the pressure of the pipe-net lowers to the lower limit of the pressure stabilization, the water-supplementing pump restarts. In this repeated way, the water-supplementing pump continues working to make the pressure of the pipe-net kept in between both upper and lower limits of the pressure stabilization. In case of a fire, the hydrant or shower opens and the pressure of the pipe-net continues lowering, causing the work of the water-supplementing pump unable to meet with the requirement on the said pressure, the said pressure is then maintained and the ten-min emergency fire fighting water is supplied by the water pressed out of the pneumatic tank.

4 QLC(Y SERIES EMERGENCY FIRE FIGHTING WATER SULY EQUIMENT The water pump in the equipment is used as a watersupplementing pump (with the water-supplementing time decided by the pump's flow and required to meet with the flow of the water used for the pressure stabilization of the fire fighting pipe-net, therefore it is suggested use a water pump of a small flow as can as possible, provided that the water used for the pressure stabilization can be met with (so as to reduce the equipment's installation space and the manufacturing cost; the working pressure is estimated upon the desired static-water pressure in the most adverse point of the pipe-net, so select a water pump mostly closed to the performance point upon both working flow and pressure.

When to use foot bolts, preset the foot holes upon the size in the table and, after get it positioned, lay down the bolts and then pour concrete..both sewage port and pressure discharge port are screw connected and other joints are flange connected.. See the failure troubleshooting of their own for the failures with the pump, electric control cabinet.. Connect the control circuit correctly upon the electric control wiring diagram.. Before work, check and get all the valves at their right open-close positions.. After the equipment is put into normal work, it is -7 / suggested to manually drain out the water inside of the pump, - if not working for a long time, in a fixed time (-7days/once and let each pump run for -min.. Set an upward-drawing device (such as a vacuum pump, a vacuum tank etc. in case of upward-sucking water leading.. Inspect the pneumatic tank and safety valve once a year.
