Abstract
The utility model proposes without negative pressure constant pressure water supply equipment.Comprise water tank, water tank is placed in the top in room, water tank bottom has pipeline in parallel with some unit fixed on water pump suctions, feed pipe is connected after the parallel connection of some water delivery side of pump parallel pipelines, on feed pipe, side is connected to damper, water pump is electrically connected frequency-conversion control cabinet, is connected after the pipeline of water tank bottom separately has a bypass pipe to be connected in series a gate valve with feed pipe.The utility model has following beneficial effect: solve by installing damper on common constant pressure water supply equipment additional the problems that water user brings less, and problem of water consumption when being solved user's power-off such as vast remote countryside, factories and miness by measure water tank being put and installs additional by-pass line.
Description
Technical field:
The utility model relates to supply equipment field, is specifically related to without negative pressure constant pressure water supply equipment.
Background technology:
Current tap water generally adopts ripe constant pressure water supply system, namely in parallel by several supply-water pump, constant pressure water supply controller and pump motor frequency conversion is adopted to ensure the water yield change object that still pressure of supply water is constant, in general, the constant quantity depended on water user of pressure, user is more, pressure is more stable, the work start and stop of water pump are so not frequent yet, impact for motor and control is also less, otherwise, corresponding vast remote countryside, the users such as factories and miness, user is fewer, electric motor starting is more frequent, to motor, the impact of frequency converter and control system is also larger, the use pressure of user is also unstable simultaneously, when power failure, user is also subject to direct impact with water.
Utility model content:
The utility model be intended to propose for the few user's service condition such as vast remote countryside, factories and miness of water user without negative pressure constant pressure water supply equipment.
The technical solution of the utility model is: without negative pressure constant pressure water supply equipment, comprise water tank, water tank is placed in the top in room, water tank bottom has pipeline in parallel with some unit fixed on water pump suctions, feed pipe is connected after the parallel connection of some water delivery side of pump parallel pipelines, on feed pipe, side is connected to damper, and water pump is electrically connected frequency-conversion control cabinet.
Be connected with feed pipe after the pipeline of water tank bottom separately has a bypass pipe to be connected in series a gate valve.
The utility model has following beneficial effect: solve by installing damper on common constant pressure water supply equipment additional the problems that water user brings less, and problem of water consumption when being solved user's power-off such as vast remote countryside, factories and miness by measure water tank being put and installs additional by-pass line.
Accompanying drawing illustrates:
Accompanying drawing 1 is Split type structure schematic diagram of the present utility model.
1-water tank in figure, 2-frequency-conversion control cabinet, 3-water pump, 4-damper, 5-gate valve, 6-feed pipe.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, without negative pressure constant pressure water supply equipment, comprise water tank 1, water tank 1 is placed in the top in room, pipeline and some water pumps 3 inlet parallel are arranged at water tank 1 bottom, feed pipe 6 is connected after the outlet parallel pipeline parallel connection of some water pumps 3, on feed pipe 6, side is connected to damper 4, water pump 3 is electrically connected frequency-conversion control cabinet 2, frequency-conversion control cabinet is according to the running frequency of the start and stop of hydraulic pressure control water pump and the quantity of start and stop and water pump, damper is equivalent to the water capacity added in feed pipe, adds the stable of hydraulic pressure, reduces variation in water pressure and the impact to electrical system.
The pipeline of water tank 1 bottom is connected with feed pipe 6 after separately having a bypass pipe to be connected in series a gate valve 5, and when power failure, opened by gate valve 5, water tank 1 hydraulic pressure of eminence supplies water directly to user.
The utility model has following beneficial effect: solve by installing damper on common constant pressure water supply equipment additional the problems that water user brings less, and problem of water consumption when being solved user's power-off such as vast remote countryside, factories and miness by measure water tank being put and installs additional by-pass line.
