Protection device for submersible pump

Abstract

The invention discloses a protection device for a submersible pump. The protection device comprises a pump body, a protection mechanism, a filtering mechanism and a fixed supporting mechanism. The pump body is connected to an inner cavity of the protection mechanism, a water inlet of the pump body is connected with the filtering mechanism, and the filtering mechanism is connected with three sets of smashing mechanisms. The protection mechanism comprises an upper protection barrel, a lower protection barrel and arc plates, wherein openings are formed in the bottom end of the upper protection barrel and the top end of the lower protection barrel, and arc-shaped clamping grooves allowing the water inlet of the pump body and a water outlet pipe to penetrate through are formed in the side facesof the upper protection barrel and the lower protection barrel. The bottom end of the upper protection barrel and the periphery of the lower protection barrel are each provided with two sets of symmetrically-arranged arc plates in a welded mode, the arc plates of the upper protection barrel and the arc plates of the lower protection barrel are connected and fixed through a plurality of sets of connecting bolts with nuts, and sound absorption layers and sound insulation layers are bonded to inner cavities of the upper protection barrel and the lower protection barrel. The protection device forthe submersible pump not only has good protection and noise reduction effects, but also can perform stable supporting.

Description

technical field [0001] The invention belongs to the technical field of submersible pumps, and in particular relates to a protective device for submersible pumps. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. Liquids, gas mixtures and liquids containing suspended solids can also be transported. The technical parameters of pump performance include flow rate, suction lift, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric pumps, vane pumps and other types. Positive displacement pumps use the change in the volume of their working chambers to transfer energy; vane pumps use the interaction between rotating blade...
