Abstract
The invention discloses a kind of double check valve (DCV) screw rod self-priming pumping system, it is characterized in that, the motor (2) being connected is driven including pump head (1) and with pump head (1), the water inlet (3) of the pump head (1) is provided with water check valve (5), the delivery port (4) of the pump head (1) and also is provided with water check valve (5).The advantage of the present invention compared with prior art is：The present invention is when water pump is out of service; the pressure that pressurized tank is produced will not be taken to inside pump head; negative pressure will not be produced when water pump restarting; can normally it start; the normal operation of water pump system is protected, and when having a power failure, 48V 60V sockets can be transmitted electricity by storage battery; the production requirement for having a power failure and not stopping work is met, the operating efficiency of the pump housing is improved.
Description
Technical field
The present invention relates to pump technical field, more particularly to a kind of double check valve (DCV) screw rod self-priming pumping system.
Background technology
The existing pump housing generally has a water check valve in water inlet, when water pump stops, and the pressure inside pressurized tank can band
To pump head, when water pump restarting, negative pressure is had unavoidably, difficulty in starting is easily damaged water check valve.The other existing pump housing is only
220V voltages can be supported to run, if can not be run when having a power failure, based on this, a kind of double check valve (DCV) screw rod self-priming pumping system is now studied,
This problem is solved well.
The content of the invention

The present invention is achieved by the following technical solutions：A kind of double check valve (DCV) screw rod self-priming pumping system, including pump head with
And the motor being connected with pump head drive, the water inlet of the pump head, which is provided with water check valve, the delivery port of the pump head, also to be provided with
Water check valve.
One of preferred embodiment as the present invention, in addition to pressurized tank, the pressurized tank pass through outlet conduit and delivery port
Communicate.
One of preferred embodiment as the present invention, is provided with seal between the outlet conduit and delivery port.
One of preferred embodiment as the present invention, the water inlet is communicated with inlet channel, and the inlet channel is in depth
Lower water.
One of preferred embodiment as the present invention, is provided with seal between the inlet channel and water inlet.
One of preferred embodiment as the present invention, in addition to converter, the converter are connected with motor.
One of preferred embodiment as the present invention, the converter is provided with double sockets.
One of preferred embodiment as the present invention, described pair of socket is respectively 220V sockets and 48V-60V sockets.
The advantage of the present invention compared with prior art is：The present invention is when water pump is out of service, the pressure that pressurized tank is produced
It will not take to inside pump head, will not produce negative pressure when water pump restarting, can normally start, protect water pump system just
Often operation, and when having a power failure, 48V-60V sockets can be transmitted electricity by storage battery, the production requirement for having a power failure and not stopping work is met,
Improve the operating efficiency of the pump housing.
