Efficient intelligent self-control self-sucking pump

Abstract

The invention relates to an efficient intelligent self-control self-sucking pump which comprises a pump body, a frequency conversion motor, an automatic exhaust device and an intelligent control box.The intelligent control box is arranged on the automatic exhaust device.A liquid inlet is formed in the bottom of the pump body.A liquid outlet is formed in the side face of the pump body.An inlet bent pipe is flange connection with the liquid inlet.A flow guiding pipe is in flange connection with the liquid outlet.An automatic blowoff valve is arranged on the flow guiding pipe.A pump cover is arranged between the pump body and the frequency conversion motor.An inner cavity formed by the pump body and the pump cover is a pump cavity.A centrifugal impeller is arranged in the pump cavity.The pump cover is provided with an induction probe and a vaccumizing exhaust hole.An exhaust pipeline is arranged on the vacuumizing exhaust hole.The automatic exhaust device is communicated with the pump cavity through the exhaust pipeline.The frequency conversion motor, the automatic blowoff valve, the induction probe and the automatic exhaust device are electrically connected with the intelligent control box through signal lines.The efficient intelligent self-control self-sucking pump is simple and compact in structure and high in intelligent degree, the self-sucking function is completed through the independent automatic exhaust device, and therefore the hydraulic efficiency is effectively improved.

Description

technical field [0001] The invention relates to a self-priming pump, in particular to a high-efficiency self-control self-priming pump, which belongs to the technical field of mechanical equipment. Background technique [0002] Self-priming pumps are often used in industries such as iron and steel, metallurgy, mining, electric power, petroleum and petrochemical, papermaking, and sewage treatment. Conventional self-priming pumps use a pump casing plus a water tank. When the impeller rotates, the gas and water are mixed and then discharged from the pump chamber, and the gas is separated from the water by the water tank, and the gas is discharged out of the pump. Make the inlet of the pump body form a certain degree of vacuum, so as to realize the function of self-priming. The self-priming time of this kind of self-priming pump is long, and because the liquid stays in the water tank for a long time, corrosion of the pump cavity will inevitably occur. If the self-priming pump ...

Problems solved by technology

If the self-priming pump is prone to freezing in the low-temperature environment in the north, the material will freeze and solidify in the pump chamber, blocking the pump chamber, which will not only affect the smoothness of the pump inlet, but also cause the water tank and pump casing to freeze and crack.

In addition, most of the existing self-priming pumps only consider self-priming and do not pay attention to hydraulic efficiency during the pump design process, making them low-efficiency and high-energy-consuming equipment among centrifugal pumps.
