In order to achieve the above object, the technical scheme that the utility model adopted provides a kind of negative pressure-free water supply plant pressure monitoring device, comprises inlet channel, and described inlet channel is connected with the current stabilization jar, described current stabilization jar is connected with the water pump group, and described water pump group is connected with outlet conduit; Before described inlet channel total valve, be provided with the intake pressure watch-dog; Pressure monitor device be provided with pump before described water pump group water inlet before is provided with the discharge pressure watch-dog before the total delivery port of described outlet conduit; Pressure monitor device, discharge pressure watch-dog are transported to the Based Intelligent Control cabinet to the force value that monitors in signal of telecommunication mode before described intake pressure watch-dog, the pump; Described water pump group is connected by the signal of telecommunication with the Based Intelligent Control cabinet.
Further, described inlet channel place is provided with into water standby pressure transmitter; Be provided with the preceding pressure transmitter of pump before the described water pump group.
Further, connect with described water pump group and be provided with air pressure tank; Be arranged in parallel stabilized pressure pump with described water pump group, described stabilized pressure pump is connected by the signal of telecommunication with the Based Intelligent Control cabinet.
In the utility model, before the inlet channel total valve, be provided with the intake pressure watch-dog, monitoring intake pressure value; The intake pressure value that intake pressure watch-dog handle monitors is transported to the Based Intelligent Control cabinet in the mode of the signal of telecommunication.The Based Intelligent Control cabinet is set an intake pressure lower limit, and when the intake pressure value that monitors during less than the water inlet lower limit, equipment is reported to the police automatically, and the water pump group stops or low-frequency operation; When intake pressure returned on the intake pressure lower limit, the water pump group was resumed operation.The Based Intelligent Control cabinet is also set a normal water supply range of pressure values, when the intake pressure monitor monitors to intake pressure value when exceeding the normal water supply range of pressure values, equipment is reported to the police automatically, and system switches to into water standby pressure transmitter work, guarantees the normal water of user.
In the utility model, before the water pump group, be provided with pump before the pressure monitor device, the monitoring water pump before force value; Force value is transported to the Based Intelligent Control cabinet in the mode of the signal of telecommunication before the pump that pressure monitor device handle monitors before the pump.When force value before the pump that monitors and intake pressure value difference value surpassed the scope of setting, equipment was reported to the police automatically, reminded administrative department that dirt separator is cleaned.
In the utility model, before the total delivery port of outlet conduit, be provided with the discharge pressure watch-dog, the pressure of monitoring equipment delivery port; The discharge pressure watch-dog is monitoring to such an extent that the delivery port force value is transported to the Based Intelligent Control cabinet in the mode of the signal of telecommunication, and the Based Intelligent Control cabinet is set a frequency as the desired value that supplies water to the user; When delivery port force value and desired value relatively near the time, by frequency adjustment delivery port pressure is conformed to given user's water supply target value; When main pump has only a frequency conversion job, and when being operated in low frequency within a certain period of time, main pump enters resting state automatically.
When delivery port pressure reached customer requirements, main pump entered resting state, was provided with in addition to wake pressure up.When the delivery port pressure stability in setting range, satisfy under the water supply requirement situation, when flow is very little, carry out the low discharge moisturizing by air pressure tank, stabilized pressure pump does not start, main pump does not wake up; Can not continue the moisturizing pressurize at air pressure tank, when pressure was low to moderate the stabilized pressure pump starting pressure, stabilized pressure pump started, and main pump does not wake up; When pressure reached stabilized pressure pump termination of pumping pressure, the stabilized pressure pump autostop carried out the low discharge moisturizing by air pressure tank again.
Remarkable result of the present utility model is, " the lack of water negative pressure " that has produced when having avoided the pipe network ability less than discharge, controlled owing to " transient flow negative pressure " produces potential safety hazards such as air bag, vapour lock, pressure oscillation, refluence and water hammer, guarantee the safety and the comfortableness that supply water, reached energy-saving effect preferably.
Description of drawings
Fig. 1 is the schematic diagram of a kind of negative pressure-free water supply plant pressure monitoring device of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model comprises inlet channel 1, and inlet channel 1 is connected with current stabilization jar 6, and current stabilization jar 6 is connected with water pump group 7, and water pump group 7 is connected with outlet conduit 11; Before the total valve 9 of inlet channel 1, be provided with intake pressure watch-dog 2; Pressure monitor device 3 be provided with pump before water pump group 7 water inlets before is provided with discharge pressure watch-dog 4 before the total delivery port of outlet conduit; Pressure monitor device 3, discharge pressure watch-dog 4 are connected with Based Intelligent Control cabinet 5 by the signal of telecommunication before intake pressure watch-dog 2, the pump.
During water inlet lower limit that the intake pressure value that monitors when intake pressure watch-dog 2 is set less than Based Intelligent Control cabinet 5, equipment is reported to the police automatically, and water pump group 7 stops or low-frequency operation; When intake pressure returned on the intake pressure lower limit, water pump group 7 was resumed operation.Based Intelligent Control cabinet 5 is set a normal water supply range of pressure values, when the intake pressure value that monitors when intake pressure watch-dog 2 exceeds the normal water supply range of pressure values, equipment is reported to the police automatically, and system switches to into water standby pressure transmitter work, guarantees the normal water of user.When force value before the pump that pressure monitor device 3 before the pump monitors and intake pressure value difference value surpassed the scope of setting, equipment was reported to the police automatically, reminded administrative department that dirt separator is cleaned.
Discharge pressure watch-dog 4 is monitoring to such an extent that the delivery port force value is transported to Based Intelligent Control cabinet 5 in the mode of the signal of telecommunication, and Based Intelligent Control cabinet 5 is set a frequency as the desired value that supplies water to the user; When delivery port force value and desired value relatively near the time, by frequency adjustment, delivery port pressure is conformed to given user's water supply target value; When main pump group 7 has only a frequency conversion job, and when being operated in low frequency within a certain period of time, main pump enters resting state automatically.
When delivery port pressure reached customer requirements, main pump entered resting state, was provided with in addition to wake pressure up.When the delivery port pressure stability in setting range, satisfy under the water supply requirement situation, when flow is very little, carry out the low discharge moisturizing by air pressure tank 10, stabilized pressure pump 8 does not start, main pump does not wake up; Can not continue the moisturizing pressurize at air pressure tank 10, when pressure was low to moderate stabilized pressure pump 8 starting pressures, stabilized pressure pump 8 started, and main pump does not wake up; When pressure reached stabilized pressure pump 8 termination of pumping pressure, stabilized pressure pump 8 autostops carried out the low discharge moisturizing by air pressure tank 10 again.
