The side of electromotor.Using this kind of technical scheme, when the valve is open, the tail gas that electromotor produces is directly over exhaustor tail end
Discharge, when valve, the tail gas that electromotor produces is discharged through jet vacuum pump.
2nd, a kind of self-priming water jet pump of the present invention, is provided with check-valves between its vacuum orifice and water inlet, check-valves
Vacuum orifice is pointed in direction.Using this kind of technical scheme, check-valves can prevent the gas backstreaming in jet vacuum pump in the pump housing,
Further increase the reliability of device.
3rd, a kind of self-priming water jet pump of the present invention, its exhaustor is additionally provided with acoustic filter, and acoustic filter is located at through hole and sends out
Between motivation.Using this kind of technical scheme, can effectively reduce the exhaust noise of electromotor, thus when reducing self-priming water spray pump work
The noise producing.
4th, a kind of self-priming water jet pump of the present invention, can make water pump self-suction fetch water, carries using the tail gas of electromotor come evacuation
The high work efficiency of water pump, greatly reduces cost, utilizes the tail gas energy, energy-saving and emission-reduction simultaneously.
Brief description
