Description
Technical field
The utility model relates to a kind of water supply facilities, pump water supply facilities in the quiet pipe of specifically a kind of constant pressure frequency conversion.
Background technology
The water pump that general frequency-changing water supply device adopts is to use the vertical multi-stage centrifugal water pump, and its control system adopts variable-frequency control technique.Its water pump has some inevitable shortcomings:
1. installing needs special ground pedestal, requires strictness, the basic cost height.
2. operation maintenance workload is big, and maintenance period is short, consumption worker consuming time, and the maintenance cost height: as the motor bearings maintenance, the degree of tightness of gland, the anticorrosion grade of external shell all is the content that belongs to regular maintenance.
3. operational shock, noise are all bigger.The generic brand pump noise can both reach 120dB, to the surrounding environment serious interference.
4. motor exposes; Outward appearance mostly is the steel of common material, and to anticorrosion, protection against the tide is had relatively high expectations, and outward appearance is not attractive in appearance.So at existing deficiency, need a kind of employing deep well pump of design to be made into pump in the pipe, reach the purpose of improving shortcoming.
The utility model content
The purpose of this utility model is the weak point that overcomes other equipment of employing, provides a kind of project organization more reasonable, the water supply facilities of more reliable performance.
The technical scheme that its technical problem that solves the utility model adopts is: pump water supply facilities in the quiet pipe of constant pressure frequency conversion, structure comprises water pump assembly, electric controlling assembly, the diaphragm type air pressure tank, the electrical equipment control assembly that is arranged in the electrical control cubicles connects water pump assembly by circuit, the water pump group is a pump group in the pipe, being about to submersible pump is placed in the dedicated pump sleeve pipe, submersible pump one end is fixed with special stand, the other end connects with pump outlet with screwed pipe, and screwed pipe is connected with the pump block pipe is airtight with flange, pump in complete pipe of whole like this formation, the water inlet end of pump connects with soft the connecing with butterfly valve of rubber in the single pipe, water side and flap valve, FlexbleJoint and butterfly valve link, and form pumping system in one group of pipe.
Water pump assembly can be provided with pump in one to four group of pipe, is parallel between the water collecting fitting and water outlet collecting fitting.
The water inlet collecting fitting communicates with tap water inlet pipeline and outlet pipeline by butterfly valve respectively with the water outlet collecting fitting, and the other end of water outlet collecting fitting connects with the diaphragm type air pressure tank.
On pump block pipe, water pump outlet pipe, water inlet collecting fitting and water outlet collecting fitting, outlet valve is housed, pointer pressure is installed on pumping line.
At water inlet collecting fitting setting pressure switch, setting pressure switch and teletransmission pressure meter on the water outlet collecting fitting, pressure switch is connected with electric controlling assembly with the teletransmission pressure meter.
The beneficial effects of the utility model:
It is slight that pump has vibration in the pipe, and the advantage that noise is extremely low has only 35dB usually; Vertical pump then vibrates strongly, and general noise can reach 120dB.
Pump does not need regular maintenance in the pipe, and periodic maintenance is longer at interval, and motor can be non-maintaining; Mounting means is easy: can crouch, can stand, but side is flexible for installation, can not need pump house; All can in the indoor and outdoor.The whole stainless steel products of pump group, attractive in appearance, health is pollution-free.
Vertical pump then needs often to safeguard dedusting regularly and apply oil.Normal vertical for installing, need pump house, the environmental requirement strictness.It is stainless steel that the pump group has only the part parts, and the form tradition.
In sum, the utility model biggest advantage is that energy-conservation, environmental protection and installation and maintenance are easy.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the main TV structure figure of pump water supply facilities in the quiet pipe of constant pressure frequency conversion;
Fig. 2 is the plan structure figure of pump water supply facilities in the quiet pipe of constant pressure frequency conversion.
The specific embodiment
With reference to Figure of description pump water supply facilities in the quiet pipe of constant pressure frequency conversion of the present utility model is explained.
Pump water supply facilities in the quiet pipe of constant pressure frequency conversion of the present utility model, structure comprises water pump assembly, electric controlling assembly, diaphragm type air pressure tank 14, the electrical equipment control assembly that is arranged in the electrical control cubicles 1 connects water pump assembly by circuit, the water pump group is a pump group in the pipe, being about to submersible pump 6 is placed in the dedicated pump sleeve pipe 5, submersible pump 6 one ends are fixing with special stand 15, the other end connects with pump outlet with screwed pipe, and with flange with screwed pipe and 5 airtight connections of pump block pipe, pump in complete pipe of whole like this formation, in the single pipe water inlet end of pump and rubber soft connect 2 and butterfly valve connect, water side and flap valve 8, FlexbleJoint 10 and butterfly valve 13 link, and form pumping system in one group of pipe.
Water pump assembly can be provided with pump in one to four group of pipe, is parallel between the water collecting fitting 3 and water outlet collecting fitting 11.
Water inlet collecting fitting 3 communicates with tap water inlet pipeline and outlet pipeline by butterfly valve 13 respectively with water outlet collecting fitting 11, and the other end of water outlet collecting fitting 11 connects with diaphragm type air pressure tank 14.
On pump block pipe 5, water pump outlet pipe, water inlet collecting fitting 3 and water outlet collecting fitting 11, outlet valve is housed, pointer pressure 7 is installed on pumping line.
At water inlet collecting fitting 3 setting pressure switches 4, setting pressure switch 9 and teletransmission pressure meter 12 on water outlet collecting fitting 11, pressure switch 9 is connected with electric controlling assembly with teletransmission pressure meter 12.
Electrical control system based on water pump group control circuit and adopt frequency converter and PLC as the core control element, constitute a whole set of perfect intelligence control system with external pressure switch and teletransmission pressure meter.
But whole system control manual state and auto state switch, and working method is various: automatic frequency-conversion, and automatic power frequency, manual power frequency, modes such as little pump frequency conversion and sleep state satisfy the various requirement to water condition fully.Owing to by converter technique the water pump group is carried out speed governing, under the situation that guarantees constant voltage,, can in time adjust the flow of water pump group according to the water supply volume size; System enters sleep state when minimum flow; the pump group is shut down, and system is by compensating the pressure stabilization function that air pressure tank can reach pipe network, therefore with traditional non-frequency systematic comparison; native system plays the usefulness of energy conservation to greatest extent, has prevented the water pressure fluctuations of pipe network simultaneously effectively.
The water of city planting ductwork flows into from the water inlet collecting fitting during operation, enters by the water inlet arm that pump carries out supercharging in the pipe, and the current after the supercharging enter the water outlet collecting fitting from water pump outlet pipe again, enter user's pipe network system at last.
Except that the described technical characterictic of manual, be the known technology of those skilled in the art.
