Description
Technical field
The utility model relates to secondary water-supply apparatus fields, especially a kind of to be based on secondary water supply system pipeline tip hydraulic pressure
Energy saver.
Background technique
In secondary water supply system, existing no negative pressure skyscraper secondary water-supply equipment working method is all in associated mechanisms
Under effect, after the low pressure tap water of input is pressurized by the booster pump being mounted between inlet and outlet pipes,
Resident's pipeline is then input to enable users to just commonly use water.After hydraulic pressure reaches the pressure value of setting in resident's pipeline in order to prevent,
The booster pump of secondary water-supply equipment, which works always, causes one side hydraulic pressure of user pipe excessively high, and prevents the increasing of secondary water-supply equipment
Press pump, which works always, causes waste of energy and damage, and the control system of secondary water-supply equipment can be according to the water of user pipe side
The working condition of the pressure data control booster pump for being input to secondary water-supply apparatus control system host computer press, detected, when
When being input to the hydraulic pressure of user pipe more than the numerical value that upper computer control system is arranged, host computer controls booster pump through PLC module
Power failure work, when being input to the hydraulic pressure of user pipe lower than the numerical value that upper computer control system is arranged, host computer is through PLC module
Booster pump work once electrified is controlled, so that the hydraulic pressure of user pipe side be made to be maintained at stable state.
In fact, since user's evening water consumption is few, hydraulic pressure needed for pipeline is lower than water use peak in secondary water supply system
(such as water use peak on daytime phase supply equipment water outlet hydraulic pressure 1.2MPa, it is ensured that uppermost storey occupies can be used normally in phase
Domestic use of water, then with water low peak period supply equipment water outlet pipeline hydraulic pressure 1.05MPa or so, due to user's water flow and pressure
It is small, it is ensured that uppermost storey urbanite water consumption)；But due to existing secondary water supply system user pipe hydraulic pressure number collected
According to from the user pipe pressure sensor adjacent with booster pump, pressure sensor is unable to actual response user pipe least significant end
Hydraulic pressure, and existing secondary water supply system setting operating mode be exactly no matter water use peak phase or slack hours section,
One side hydraulic pressure of water outlet user pipe can be kept to be in constant state, and the preset hydraulic pressure in user pipe side is based on peak
Phase is needed with water hydraulic pressure, therefore in this case, water during guaranteeing water use peak in water slack hours section user pipe
Pressure undoubtedly will cause pressurization, and pump operation time is too long, excessively Fraquent start leads to booster pump reduced service life.In practical operation,
It is up to a hundred to the distance to tip pressure spot from underground chamber controller if arranging pressure sensor in user pipe tip pressure spot
Rice is even longer, and analog signal decaying is uncontrollable, and cable wiring manufacture difficulty is big, at high cost, therefore seldom uses in practical application.
Its booster pump of existing secondary water supply system is usually more used in parallel, and when work works together, one when stopping
It rises and stops working.This operating mode, due to more booster pump Fraquent starts in parallel, impacts especially with during water ebb
Electric current not only causes greatly waste of energy, and is easy to cause complete supply equipment service life to reduce and may cause water pump damage
It is bad (it is slightly lower with user pipe hydraulic pressure during water ebb, more days booster pumps in parallel will work once electrified, and due to being used during ebb
Water is few, in fact, more pressurization pump work very short times can mend user pipe hydraulic pressure water enough, so can frequently open
Dynamic, during the water use peak phase, since water consumption is big, more booster pump long-plays in parallel just can guarantee user's water, institute
With there is no use water slack hours section frequent starting).
