Problems solved by technology

The position of the water inlet of the traditional miniature submerged water pump is fixed, and the head is adjusted only by adjusting the area of ​​the water inlet or outlet. In the process of changing the head, the flow loss is large, and the adjustable range of the head is also narrow.
Due to the large change in the flow rate

Embodiment Construction

[0018] Further description will be given below in conjunction with the accompanying drawings of the embodiments of the present invention.

[0019] Each part shown in the embodiment of Fig. 1a~1e is, the main body (3) of miniature submerged water pump, the front cover (1) with slide rail (6), regulating valve (2), rear cover (4), power cord The wire gear (5) at the outlet and the water pump outlet (7); the motor part of the water pump is potted in the main body (3), and the impeller driven by the motor rotor is located in the water storage chamber at the front of the main body (3). The water port (7) is located above the water storage cavity. Its displacement water inlet regulating device is composed of a front cover (1) with a slide rail (6) and a regulating valve (2) with a water inlet channel. The regulating valve (2) is installed on the In the slide rail (6) of the front cover (1), the slide rail is used to regulate the movement and guidance of the valve.

Abstract

The miniature submerged water pump includes a pump body, a motor, a vane wheel, and a water inlet regulator, and features that the water inlet regulator is a variable level one and consists of a front cap with slide rail and a regulating valve with water inlet passage installed in the slide rail via a guide plate. It has novel design and makes pump inlet shift relatively to the rotating center of the vane wheel through sliding so as to regulate lift head, and wide lift head regulating range, less flow rate loss, and may be used to replace several miniature submerged pumps with different size and different life head.

Description

technical field [0001] The invention belongs to the technical field of water pumps, in particular to a miniature submerged water pump with a displacement water inlet adjustment device. Background technique [0002] AC and DC micro-submerged water pumps are widely used in products such as Boli Flowing Water Waterfall Fountain. The main body of the pump produced by different manufacturers has different shapes, and the internal components are similar or similar. The adjustment of the lift and flow is realized by adjusting the area of ​​​​the water inlet or water outlet. The position of the water inlet of the traditional miniature submerged water pump is fixed, and the head is adjusted only by adjusting the area of ​​the water inlet or outlet. In the process of changing the head, the flow loss is large, and the adjustable range of the head is also narrow. Due to the large change in the flow rate, the water volume becomes too small when it needs to be adjusted to a low lift, esp...
