Pump controller cabinet is the water supply and drainage automatic control device, in order to meet the pumps efficient and reliable use, with the main circuit short circuit, phase loss, overload and pump leakage of the pump, the stator winding over-temperature protection Features. In addition, each type is divided into single-control type, multi-pump master, standby control type, master and backup control products are equipped with automatic fault removal of the main pump, backup pump automatically into function. Now take a look at the pump control cabinet work mode has what? Pump control cabinet multi-pump control mode of work with two: A type: 1 #, 2 # can be independently controlled two pumps, but also through the float combination of connection, composed of "1 # with 2 # standby" when the flow changes or the main pump Fault, the liquid level reaches the backup pump start control point, the standby pump automatically put into work. This type is suitable for controlling the water level of two tanks, or for controlling the variable flow water supply and drainage system. Type B: When the flow changes or the main pump fails, the backup pump is automatically put into operation. One with one preparation: control 1 #, 2 # two pumps, can work in the "1 # with 2 # backup" or "2 # with 1 # backup" two kinds of work, when the main pump failure, the standby pump automatically immerse in work. Three types: Type A: Three pumps 1 #, 2 # and 3 # can be controlled independently. It can also be composed of "# 1, # 2 and # 3" or " # Reserve "or" 1 #, 3 # with 2 # reserve ", when the flow rate changes or the main pump fails, the liquid level reaches the standby pump start control point, and the standby pump automatically enters into work. This type is suitable for controlling the three pool level, or for the control of variable flow of the drainage system. B type: main pump failure, standby pump automatically set. Four: A type: can be controlled independently "1 #, 2 #, 3 #, 4 # four pumps, but also through the float combination connection, composed of" 1 #, 2 #, 3 #, with 4 # standby "or "2 #, 3 #, 4 # use 1 # backup" or "1 #, 3 #, 4 # with 2 # backup" or "1 #, 2 #, 4 # with 3 # backup", when the traffic changes or the main The backup pump is put into operation automatically when the pump breaks down, which is suitable for controlling the water level of the four basins or for controlling the variable flow water supply and drainage system Type B: The standby pump is set automatically when the main pump breaks down. Prepared: Control "1 #, 2 #, 3 #, 4 # four pumps, can work on the" # 1 #, 2 #, 3 # 4 # 2 #, 4 # with 3 # backup "four ways. When the main pump failure standby pump automatically put into work .Read more: pump valve pipe fittings exhibition water Expo Xiamen Ocean Expo Internet + Forum Yiwu Fair mold industry exhibition 2016 top ten brands interconnect (Xiamen) Technology Co., Ltd. author: Asian pumps network editor: Yao Xiaoxia (QQ / micro letter: 2355962924) http://beng.liuti.cn/ (service hotline: 400-6030-811 )
