Description
Technical field
The utility model is related to a kind of centrifugal pump, more particularly to a kind of New Centrifugal Pump.
Background technology
Self-priming centrifugal pump is so it is effect due to centrifugal force that water can be seen off.Water pump is before work, the pump housing and water inlet
The necessary tank full water row of pipe is into vacuum state, and when impeller quick rotation, blade promotes water to rotate quickly, and the water being rotating is centrifuging
It flies to from impeller under the action of power, after the water in pump is spilled over, the central part of impeller forms vacuum area.Water is in atmospheric pressure
It has been pressed onto in water inlet pipe, recycled endlessly in this way, it is possible to realize continuous pumpage by pipe network under the action of power (or hydraulic pressure).Self-priming
Centrifugation pump startup is previous will can be started into pump case full of after water, otherwise the pump housing will be caused to generate heat, shake, water yield surely
It reduces, water pump is damaged and (referred to as " cavitation erosion ") causes equipment breakdown.Generation to prevent cavitation erosion can be in the suction inlet of pump
Place increases a check valve.
The check-valves of suction inlet has double action：When pump is stopped, it can prevent liquid in the pump housing from suction
Enter pipe reflux；Just in case the liquid in suction line is drained, the liquid retained in the pump housing still ensures that the self-priming of pump.
Utility model content
In order to overcome the shortcoming of existing centrifugal pump, the utility model provides a kind of New Centrifugal Pump.
What the technical solution of the utility model was realized in：
Including pedestal, motor and the pump housing are disposed on the pedestal for a kind of New Centrifugal Pump of this programme；The pump
Pump shaft is provided on body, the shaft of the motor is connected by shaft coupling with pump shaft；The junction of the pump housing and pump shaft is set
It is equipped with filling container；The pump shaft is provided with rotating speed detector with shaft coupling junction, which is electrically connected with motor, institute
The side for stating the pump housing is provided with suction inlet, which is provided with filter screen；It is provided at the top of the pump housing
Outlet is provided with flow velocity detector on the outlet, which is electrically connected with motor；The pump housing suction inlet enters
Tubaeform mouth is provided at mouthful；The diameter of the tubaeform mouth pipeline is gradually reduced to Way in；It is set in the tubaeform mouth
It is equipped with tabletting；The diameter of the tabletting is identical with tubaeform mouth inlet diameter；The outside of the tabletting is provided with gasket；Institute
The exit for stating tubaeform mouth is provided with fastening frame；The fastening frame is in cross structure；It is provided on the fastening frame and tabletting
The spring being connected；The tabletting is tightly connected under the action of the spring with tubaeform mouth inlet.
The utility model is beneficial in that：It is simple in structure, it is easy to use, when pump is stopped, can prevent from pumping
Internal liquid flows back from suction line, in addition, when the liquid in suction line is drained, the liquid retained in the pump housing still ensures that
The self-priming of pump.

Net 16；The top of the pump housing 3 is provided with outlet 8, is provided with flow velocity detector 15 on the outlet 8, the flow velocity detector
15 are electrically connected with motor 2；The inlet of 3 suction inlet 7 of the pump housing is provided with tubaeform mouth 9；9 pipeline of tubaeform mouth it is straight
Radial direction Way in is gradually reduced；Tabletting 10 is provided in the tubaeform mouth 9；The diameter of the tabletting 10 and tubaeform mouth 9
Inlet diameter is identical；The outside of the tabletting 10 is provided with gasket 11；The exit of the tubaeform mouth 9 is provided with fastening
Frame 12；The fastening frame 12 is in cross structure；The spring 13 being connected with tabletting 10 is provided on the fastening frame 12；The pressure
Piece 10 is tightly connected under the action of spring 13 with tubaeform 9 inlet of mouth.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment, it is impossible to be construed as limiting the scope of the utility model.It is all to be made according to application scope of the utility model
