Description
Technical field
It the utility model is related to secondary water-supply more particularly to air pressure tank.
Background technology
General supply equipment Introduction on Principle is as shown in Figure 1：Equipment detects outlet pressure by second pressure sensor 14, will
Detecting value and setting value are compared, and calculate needs increased pressure on original pressure-based of import pipe network, it is determined that increasing
Press pump puts into platform tricks and frequency converter output frequency and realizes constant pressure water supply with water-carrying capacity pressure curve to chase after patch user.Pass through flow
Sensor 13 detect user's water-carrying capacity, when user need flow in the range of the auxiliary pump metered flow of low discharge when, system by
The auxiliary pump operation constant pressure water supply of low discharge.Be pressurized the pump operation starting stage, system to user supply water while also to diaphragm pneumatic
Tank 5 supplements energy (moisturizing accumulation of energy) until gas pressure is equal to system constant-pressure pressure in diaphragm-type air-compressed tank 5.Pass through flow sensing
Device 13 detects water consumption, and low discharge termination of pumping dormancy is automatically switched to when water consumption is less than the 10% of the specified water supply flow of auxiliary pump
Working condition, the wholly off operation of booster pump, into dormancy, change and maintain low discharge to have by the diaphragm-type air-compressed tank 5 Jing Guo accumulation of energy

The purpose of water supply.When the high pressure water in boosting energy-saving type diaphragm-type air-compressed tank is finished, the hydraulic pressure in service pipe is begun to decline,
As the hydraulic pressure that second pressure sensor 14 is detected in service pipe 1bar lower than setting value or so, control system, which is waken up, moves back
Go out dormancy, the first hydraulic pressure constant pressure water supply is recovered by supercharging pumping array 11,12, so circulation meets that user wants to pressure and flow
Ask.
For same boosting energy-saving type diaphragm-type air-compressed tank, the height that laminates and can be provided during its dormancy after pump K4 is added
Pressure water capacity, which can reach, does not increase more than 5 times of water capacity when laminating pump K4.Such as：The diaphragm type of one 100 liters of total measurement (volume)
Air pressure tank, gas initial pressure 9bar, the first hydraulic pressure are 10bar, the quilt when the first hydraulic pressure is down to 9bar to booster pump after dormancy
Wake up, calculated by Boyle's law P1V1=P2V2：The dormancy that can be provided during boosting energy-saving type diaphragm-type air-compressed tank is not increased
It it is 10 liters with water capacity；When increase laminates pump K4, the second hydraulic pressure can reach 20bar, and corresponding dormancy is increased to 55 with water capacity
Rise, it is clear that increase after laminating pump K4, the high pressure dormancy that can be provided is original 5.5 times with water capacity.Assuming that the stream of user
Amount is balanced, then the dormancy time of supercharging pumping array 11,12 is original 5.5 times, can reduce supercharging pumping array 11,12 and open
Dynamic 4.5 times, because of booster pump, in low discharge and startup, operational efficiency is very low, laminates pump K4 and shortens low discharge run time and subtract
Lack dormancy pump startup number, therefore significantly reduce the consumption of equipment electric energy.Actual motion experiment shows, uses boosting energy-saving
Type diaphragm-type air-compressed tank can make the overall efficiency of supply equipment improve more than 8%.Produced when decreasing night frequent starting simultaneously
Raw noise.
