Problems solved by technology

However, if the water inlet of the water chamber is too close to the bottom surface of the container or the tank, the water inlet section will be reduced, which will limit the flow rate of the water pump, resulting in a significant reduction in the pumping efficiency of the vertical submersible pump.

Embodiment Construction

[0027] Further details will be given below in conjunction with the preferred embodiments shown in the accompanying drawings.

[0028] The present invention relates to the method that makes the residual water level in the container reach the minimum based on the vertical submersible pump, such as figure 1 and figure 2 As shown, the vertical submersible pump includes a vertically arranged pump body 1, a water chamber 2 arranged below the pump body 1, and an inlet filter plate 3 arranged below the water chamber 2; the water chamber The chamber 2 includes a water chamber water inlet 21, a water chamber water outlet 25 and an outer peripheral wall 22 of the water chamber. The pump body 1 pumps water into the water chamber 2 through the water chamber water inlet 21 and passes through the water chamber. The water outlet 25 discharges water from the water chamber 2; the water inlet filter plate 3 is used as a support base to place the vertical submersible pump on a working plane; es...

Abstract

The invention relates to a method for making residual water level in a container reach the lowest point and a vertical submersible pump. The vertical submersible pump comprises a pump body (1), a water cavity chamber (2) and a water inlet filter plate (3); in particular, the surrounding of the bottom of a water cavity chamber peripheral wall (22) is provided approximately and evenly with n first lug bosses (23) so as to form n filtering water inlets (24) between the water cavity chamber peripheral wall (22) and the water inlet filter plate (3); and a distance H213 between a water cavity chamber inlet (21) and the water inlet filter plate (3), an inlet cross section area of the n filtering water inlets (24) and sigmaS24 and a maximum height H24 of the veridical direction of the filtering water inlets (24) satisfy the relations that H213 is more than or equal to S21/L21, sigmaS24 is more than or equal to S21 and H24 is less than H213 at the same time. The method and the vertical submersible pump design rationally a geometric construction of the water cavity chamber (2), thereby making the shallowest pumping depth of the vertical submersible pump reach at the lowest point under the premise of not influencing flow rate.

Description

technical field [0001] The invention relates to a submerged water pump in direct contact with liquid and its realization method, in particular to a vertical submersible pump which can basically pump out the liquid at the bottom of the container and its realization method. Background technique [0002] Vertical submersible pumps are commonly used devices for pumping out liquids in containers or tanks. The prior art vertical submersible pump includes a vertically arranged pump body, and a water chamber and an inlet filter plate arranged below the pump body; the pump body pumps water into the water chamber through the water inlet of the water chamber and passes through The water outlet of the water chamber discharges water out of the water chamber, and then draws out the liquid in the container or the tank. Due to the limitations of the vertical submersible pump's own structure, there will always be some liquid remaining at the bottom of the container that cannot be pumped out...
