Abstract
The utility model relates to a submersible pump case type laminating pressure feedwater unit that is directly connected to municipal tap water pipeline for pressurizing. The device comprises a case, a submersible pump, a tube sheet flange, an ellipse end plate, a feed-water remote transmitting pressure gauge, a waterexit remote transmitting pressure gauge, a pipeline filter, a backflow preventer and an electric control cabinet etc. The submersible pump is arranged in the case and is fastened to the tube sheet flange via binding bolt. The feed-water part and the waterexit part of the submersible pump are isolated with tube plate flange. Moreover, feed-water remote transmitting pressure gauge is arranged at the inlet. The utility model has the advantages of simple structure, low cost, easy installation, small size, safe water supply and complete protection functions etc. The utility model can be widely applied for secondary pressurizing occasions where direct pumping from municipal pipeline network is allowed.
Description
1, technical field
The utility model relates to a kind of secondary pressurizing feedwater equipment, specifically a kind of submersible pump shell-and-tube pressure-superposed water supplying facility.
2, background technology
Along with fast development of national economy, the construction development of China urban water supply system is very fast, the urban water supply ability generally improves, many cities directly tentatively possess from the basic condition of city planting ductwork extraction second pressure water supply, in addition the raising of living standards of the people and more and more hope can avoid the secondary pollution of water quality, water supply pressurizing feedwater equipment that again can more energy-conservation economize on electricity replaces traditional pond, water tank pressurizing feedwater equipment, and solve the no-negative-pressure water supply equipment of the steady flow compensator of this technical scheme and vacuum suppresser pattern owing to exist complex structure, the deficiency that cost is high can not be popularized on market well.
3, utility model content
The purpose of the present utility model provide a kind of simple in structure, cost is low, easy for installation, take up an area of less, water supply security health, the complete submersible pump shell-and-tube pressure-superposed water supplying facility of defencive function.
The technical scheme that its technical problem that solves the utility model adopts is: device has submersible pump in shell, submersible pump is fixed on the tube sheet flange by fastening bolt, current enter ellipse head by the tube sheet flange from the shell water inlet after the submersible pump pressurization, exported by delivery port again.The tube sheet flange is kept apart water inlet and water outlet two parts of submersible pump, and constitutes the pressure piping of submersible pump with ellipse head and delivery port.When causing the submersible pump operation municipal tap water pipe network is caused that local pressure descends for the hypotony that prevents water inlet, near user's the normal water influence, be provided with into water teletransmission pressure meter in the water inlet, when the pressure of water inlet is lower than a certain setup pressure value, submersible motor energy automatic shutdown protection; When water inlet pressure was higher than a certain setup pressure value, submersible pump entered the shutdown resting state, and the user water was crossed the by-pass line that is provided with flap valve by running water pipe Netcom and directly supplied water this moment.For the healthy prevention that reaches national regulation requires and the submersible pump purpose of safe operation, before water inlet, be provided with the backflow preventer that filter pipeline device and anti counter-flowing are polluted, on the water inlet shell of submersible motor, offer simultaneously the sewage draining exit of maintenance usefulness and the power supply seal that the submersible pump power line is passed through, electrical control cubicles then is to realize the frequency conversion or the power frequency control of submersible pump by the water inlet teletransmission pressure meter of submersible pump and water outlet teletransmission pressure meter, to satisfy user's water requirement.
