Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0024] Such as Figure 1-4 As shown in the figure, a control loop of a one-use and one-standby regulator pump for fire protection includes:
[0025] A control circuit 100 for the commonly used stabilized pump motor 300 to control the operating state of the commonly used stabilized pump motor 300;
[0026] A control loop 200 of the standby voltage stabilizing pump motor 400 for controlling the running state of the standby voltage stabilizing pump motor 400;
[0027] A power supply circuit for supplying power to the common voltage stabilizing pump motor 300 and the spare voltage stabilizing pump motor 400;
[0028] The pressure detection circuit 400 that controls the start of the common regulator pump motor 300 and the stop of the backup...

The invention discloses a control loop for a common stabilized pressure pump and a standby stabilized pressure pump for fire protection. Running states of motors of the two fire protection stabilized pressure pumps (including the common stabilized pressure pump and the standby stabilized pressure pump) are controlled by setting a stabilized pressure pump secondary loop; by arranging the common stabilized pressure pump and the standby stabilized pressure pump, one of the common stabilized pressure pump and the standby stabilized pressure pump runs according to the equipment states of the common stabilized pressure pump and the standby stabilized pressure pump to prevent the situation that a single stabilized pressure pump breaks down and can not normally run; starting and stopping of the common stabilized pressure pump motor and the standby stabilized pressure pump motor are controlled by setting pressure detection signals (low-pressure pumping and high-pressure tripping stopping) through fire protection equipment pipelines, and starting and stopping or remote linkage can be achieved; the secondary loop for the common stabilized pressure pump and the standby stabilized pressure pump for fire protection is suitable for control of various fire protection motors, and use requirements are met.
Description
technical field [0001] The invention relates to a circuit, in particular to a control circuit of a one-use-one-standby regulator pump for fire protection. Background technique [0002] Existing fire-fighting water supply pumps are all equipped with only one, but the fire-fighting water supply pump is prone to fail to operate normally due to failure, seriously affecting the fire-fighting water supply, and is a relatively large safety hazard for fire-fighting water. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The purpose of the present invention is to provide a control circuit for a fire-fighting one-use-one-standby stabilized pump, aiming to solve the problem that the existing fire-fighting water supply pump is equipped with only one, which is prone to malfunction and cannot supply water normally. [0005] Technical scheme of the present invention is as follows: [0006] A control circuit for a one-use and...
