Stand by a water pump, one with a wiring diagram for water pump, water pump with a spare circuit wiring diagram

What is the one with a prepared water pump?

one with a prepared: two as spare pumps, pump can rotate each other according to the process of setting work, only one pump work. Use a case is opened two pump at the same time, a can meet the demand, the other as a maintenance or the use of job rotation, so each pump is full of water system configuration. And a case is to use two of the three pump can meet the demand, the other as a maintenance or rotation use at work, so that each pump is the half full of water allocation system. Generally is a with a case, in order to prevent the failure or maintenance, ensure the pump water run continuously.

yituo 2: a variable frequency pump, a pump power frequency. When the output frequency of variable frequency water pump up to 50 hz, power frequency pump automatic start, and then with variable frequency pump pressure adjustment. When pressure conditions meet the set conditions, turn off the power frequency pump, variable frequency pump only adjust the pressure. Yituo N the same, just only a variable frequency pump, N is the number of pump power frequency. A point 2: a frequency converter, and at the same time to control two pumps, namely: two pumps are variable frequency pumps.

and a standby pump should be more long used, one with a prepared too waste, such as the nine pumps, six sets of operation, three set aside. But in order to ensure the safe and continuous operation, three pumps, common to two run a backup, low coefficient of insurance. In water supply and drainage design specifications, water distribution room to use a case, group is a dual-use for water Wells. Industry in order to avoid the stop to the equipment damage due to water pump, so generally used two groups of pumps in parallel, a backup, in case one of the alternative for servicing. Two groups of pump pipes in parallel.

all explain conclusion is: prevent maintenance.

pumps use a spare circuit wiring diagram:

select standby pump, with only one pump work, start a overload another switch

water pump with a case of secondary circuit wiring diagram:

circuit diagram refers to use chart the way used to express a certain process state of affairs. Here, the transaction process lines are used to represent, it is because, in the circuit diagram of the final target point is the transaction completed.

two with a frequency conversion water supply equipment for product features:

1, adopt import frequency conversion governor, according to the need to set pressure, adjust the motor speed, according to the variation of water to equipment pressure variable water pump run efficiently, save unnecessary head, energy-saving effect is remarkable.

2, USES the microcomputer control, high degree of automation, easy management, with input and output overvoltage, undervoltage, over current, short circuit protection function, safe and reliable operation. Motor adopts the soft start, no impact current, low noise, long useful life.

3, with a fault display and submitted to the function and reservoir water level automatic control function.

4, equipment in a small flow water or fire when regulated by the pump and pressure tank water supply, into the step to reduce the power consumption. Ensure the safety of the fire water system stability, and is required by the 'norm' fire storage volume.

5, with functions of automatic and manual inspection, to ensure that the fire pump to avoid rust, guarantee the normal operation.

6, can automatically complete interface circuit, there are connected with fire control center, remote control, communication and function.

7, used for hot water circulation with the overpressure of the water replenishing and pressure fixing system and discharge function.
