Description
Technical field
The present invention relates to environmental protection water supply field, particularly relate to greening water supply converter plant.
Background technology
At present, the size pump of the pressurization water system on market is in conjunction with constant pressure water supply device, general is all adopt little pump frequency conversion, greatly pump soft start to be switched to the mode of power frequency operation, this will cause large pump in start-up course, easily occur pressure superelevation and the phenomenon such as little pump low-frequency operation or large pump frequent start-stop, affect normal water supply.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of product with compact structure, multiple functional, instead of the water supply installations such as traditional water tower, high level cistern, saved construction investment, shortened construction period, avoid water quality two and provide pollution, energy-saving effect afforests water supply converter plant significantly.
For realizing the object of the invention, provide following technical scheme: greening water supply converter plant, it is characterized in that comprising rectangle bearing, bearing is placed with vacuum tank, three supply-water pumps from left to right successively, water supply line is provided with bottom vacuum tank, water supply line is provided with three arms and is connected with three supply-water pumps respectively, arm is provided with gate valve and ball valve, described water supply line is provided with gate valve and electro connecting pressure gauge, described vacuum tank sidewall is provided with row pressure mouth, and vacuum tank top is provided with safety valve.
As preferably, in vacuum tank, be provided with separation leather bag, tank body be separated into water storage cavity and air storing cavity, separate leather bag and be made up of the artificial rind of intermediate rubber layer and upper and lower surface.
As preferably, be separately provided with control system, control system electrical connection electro connecting pressure gauge, gate valve, safety valve, supply-water pump.
As preferably, supply-water pump is variable-frequency control pump.
Beneficial effect of the present invention: frequency control of the present invention, energy-efficient.Equipment introduces import variable-frequency governor, sets pressure of supply water on demand, and water pump remains at running near setting pressure, water pump is run under high efficiency operating mode, can to economize on electricity 20-40% than general supply equipment, as equipment is separately furnished with little pump and air pressure tank, power consumption can be made to decline further.Pressure degree of regulation is high, and flow can be counted continuously, and pressure of supply water can set arbitrarily.Owing to adopting PID Rule adjusting, when start and stop pump, pressure oscillation is little, and degree of regulation is high, generally at ± 0.01MPa.Automaticity is high, simple to operate.Owing to adopting intellectualized technology, unattended Automatic Control can be reached, assure feed water constant pressure.Water pump automatic cycling operating, automatically switch, first open and first stop, each pump is for subsequent use each other.Overall performance is stablized, and reliable, noise is low.Owing to adopting frequency conversion soft start mode, equipment runs balance, avoids heavy current impact, extends the application life of equipment.Compact equipment, takes up an area few, installs fast, reduces investment outlay, avoid secondary pollution.

Detailed description of the invention
Embodiment 1: greening water supply converter plant, comprise rectangle bearing 1, bearing 1 is placed with vacuum tank 2, three supply-water pumps 3 from left to right successively, water supply line 4 is provided with bottom vacuum tank 2, water supply line 4 is provided with three arms 4.1 and is connected with three supply-water pumps 3 respectively, arm 4.1 is provided with gate valve 5 and ball valve 6, described water supply line 4 is provided with gate valve 5 and electro connecting pressure gauge 7, described vacuum tank 2 sidewall is provided with row pressure mouth 2.1, and vacuum tank 2 top is provided with safety valve 8.Be provided with in vacuum tank 2 and separate leather bag 2.2, tank body is separated into water storage cavity 2.3 and air storing cavity 2.4, separate leather bag 2.2 and be made up of the artificial rind of intermediate rubber layer and upper and lower surface.Separately be provided with control system, control system electrical connection electro connecting pressure gauge 7, gate valve 5, safety valve 8, supply-water pump 3, supply-water pump 3 is variable-frequency control pump.
The water pump of water supply installation, in running, has constant speed and speed change two kinds of modes, all can carry out Flow-rate adjustment by the requirement of water supply user.During constant-speed operation, generally adopt flow restriction control.Shortcoming is that efficiency is low, energy consumption is large.Variable-speed operation is the rotating speed changing water pump in running, thus regulation output flow is with the change of applicable water supply volume, and can ensure the constant of ductwork pressure, and water pump is worked all the time under high efficiency operating mode.Because the shaft power of water pump is directly proportional to the cube of rotating speed, when rotating speed declines, shaft power declines greatly, therefore gearshift adjustment flow is improving mechanical efficiency and reducing in energy consumption, is economical rationality the most.
