Referring to fig. 1, the following technical solutions are adopted in the present embodiment: the device comprises a standby pump 1, a main pump 2, a buffer water tank 3, a diaphragm type air pressure tank 4, a PLC (programmable logic controller) 5, a volume type check valve 6, a connected check valve 7 and a buffer tank 8; install main pump 2 on the main water pipe, main water pipe one end is connected with surge tank 3, the other end passes through the pipeline and is connected with positive displacement check valve 6, be connected with diaphragm type atmospheric pressure jar 4 on this pipeline, positive displacement check valve 6 passes through the stand-by pipeline and is connected with stand-by pump 1, stand-by pump 1 is connected with buffer tank 8, buffer tank 8 is connected with surge tank 3, the main water pipe, manometer on pipeline and the stand-by pipeline is connected with PLC controller 5 respectively, PLC controller 5 is connected with surge tank 3.
The two standby pumps 1 are connected in parallel, the water inlet ends of the two standby pumps 1 are respectively connected with the buffer tank 8, and the water outlet ends are respectively connected with the volume type check valve 6.
The standby pump 1 is a common multistage pump and is used for a standby pump of a water supply system, and when the pressure of a tap water pipe network is insufficient, the pump is started.
The main pump 2 is a high-lift multi-stage pump and is used as a main pump of a water supply system, and when the pressure of a tap water pipe network is normal, the pump is started.
The buffer water tank 3 ensures that the water tank is full of water at ordinary times, and when the pressure of a tap water pipe network is insufficient, the water in the water tank is used.
The diaphragm type air pressure tank 4 is used for stabilizing the system pressure.
The PLC controller 5 automatically switches the two pumps according to the running time, and ensures that the water in the buffer water tank is in a clean state.
The positive displacement check valve 6 serves both a check function and a damping function.
The conjoined check valve 7 is connected with the valve into a whole, so that the space is saved.
The basic principles and main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
