Embodiment Construction

[0025] Such as figure 1 As shown, the screw pump with multiple sleeves spliced ​​includes a left sleeve (1), a right sleeve (6), a screw (19), a reducer (20) and a motor (21), and the screw pump with multiple sleeves spliced A stirring device (18) is provided at the bottom, a screw (22) is provided on the screw rod (19), and the left sleeve (1) and the right sleeve (6) are connected together by snap rings (7). When the screw pump spliced ​​with multiple sleeves needs to use multiple sleeves due to work, multiple left sleeves (1) and right sleeves (6) are spliced ​​end to end to form a sleeve of sufficient length.

[0026] Such as figure 2 As shown, in order to quickly connect the left sleeve (1) and the right sleeve (6), a left connecting ring (3) is provided on the right side of the left sleeve (1), and the left connecting ring (3) The lower side is provided with a connecting groove (2) equivalent to half the wall thickness of the sleeve. The depth of the connecting groove...

Abstract

The invention provides a multiple casing pipe spliced screw pump. The multiple casing pipe spliced screw pump comprises a left sleeve, a right sleeve, a threaded rod, a speed reducer and a motor and is characterized in that a stirring device is arranged at the bottom of the multiple casing pipe spliced screw pump; screw sheets are arranged on the threaded rod; the left sleeve and the right sleeveare connected together by a clamping ring; and a left connecting ring is arranged at the right side of the left sleeve. The multiple casing pipe spliced screw pump has the beneficial effects that themultiple casing pipe spliced screw pump is provided with blocking bulges and rotary fixed holes, and therefore, the splicing difficulty is reduced.

Description

technical field [0001] The invention relates to the field of liquid transportation, in particular to a screw pump with multiple casings spliced ​​together. Background technique [0002] Screw pumps are mainly used for agricultural drainage and urban drainage. They are more suitable for lifting and returning sewage with sludge in sewage plants, but their head is low and their speed is slow. In comparison, they are suitable for water with many impurities. wide range. However, although its field distance is low, it can be used as a pipeline to accelerate the direction of sewage discharge due to its great advantages in sewage discharge. However, the tube extension is limited and splicing and assembly are required. Two pipes are fastened by bolts. Since the pipes are heavy, splicing is difficult, and it is easy to cause sewage leakage due to the tight gaps and pollute the environment. Contents of the invention [0003] The purpose of this application is to provide a screw pum...
