Problems solved by technology

[0003] When the existing double-suction pump is working, impurities in the water flow into the pump casing will cause wear of the impeller and reduce the service life of the double-suction pump. In addition, it is difficult to remove impurities after entering the pump casing, and must be shut down and disassembled for cleaning

Embodiment 1

[0028] Embodiment 1: The water inlet pipe 4 is provided with an oblique filter plate 6, and the wall of the water inlet pipe 4 is provided with a first hole 7 and a second hole 8, and the first hole 7 and the second hole 8 are both Located on the same side of the oblique filter plate 6 and close to the mouth of the water inlet pipe 4, the point of the oblique filter plate 6 closest to the mouth of the water inlet pipe 4 is the highest point, and the point farthest from the mouth of the pipe is the lowest point, so The first hole 7 is set at the lowest point, the second hole 8 is set at the highest point, the second hole 8 is provided with a mesh plate 9, and the water inlet pipe 4 is covered with an annular hollow pipe 10 , the annular hollow tube 10 is arranged obliquely and at the same angle as the oblique filter plate 6, the inner wall of the annular tube is provided with two openings 11, corresponding to the first hole 7 and the second hole 8 respectively, the annular notch...

Embodiment 2

[0034] Embodiment 2: The water inlet pipe 4 is provided with an inclined filter plate 6, and the wall of the water inlet pipe 4 is provided with a first hole 7 and a second hole 8, and the first hole 7 and the second hole 8 are both Located on the same side of the oblique filter plate 6 and close to the mouth of the water inlet pipe 4, the point of the oblique filter plate 6 closest to the mouth of the water inlet pipe 4 is the highest point, and the point farthest from the mouth of the pipe is the lowest point, so The first hole 7 is set at the lowest point, the second hole 8 is set at the highest point, the second hole 8 is provided with a mesh plate 9, and the water inlet pipe 4 is covered with an annular hollow pipe 10 , the annular hollow tube 10 is arranged obliquely and at the same angle as the oblique filter plate 6, the inner wall of the annular tube is provided with two openings 11, corresponding to the first hole 7 and the second hole 8 respectively, the annular notc...

Embodiment 3

[0044] Embodiment 3: The first hole 7, the second hole 8 and the annular hollow pipe 10 are internally connected, the motor of the double-suction pump is turned on, the motor drives the impeller 3 of the double-suction pump to work, the water inlet pipe 4 generates suction, and water enters from the water inlet pipe 4 , through the oblique filter plate 6, under the interception of the oblique filter plate 6, the sundries are blocked and intercepted, and at the same time, the water flow impacts the oblique filter plate 6, and the sundries are impacted to the lowest point of the oblique filter, avoiding the interception of the sundries However, there are still filter plates, which cause blockage instead, affecting the water absorption of the double suction pump, flushing impurities from the first hole 7 into the annular hollow tube 10, and the water entering the annular hollow tube 10 circulates from the second hole 8 into the inlet In the water pipe 4, but the sundries are isola...

Abstract

The invention provides a double suction pump capable of intercepting and discharging sundries, which is characterized in that an inclined filter plate is arranged in a water inlet pipe, a first hole and a second hole are formed in the pipe wall of the water inlet pipe, the first hole and the second hole are formed in the same side of the inclined filter plate and close to a pipe opening of the water inlet pipe, a net plate is arranged on the second hole, the water inlet pipe is sleeved with an annular hollow pipe, the annular hollow pipe is obliquely arranged, the annular hollow pipe and the inclined filter plate have the same angle, two openings are formed in the inner wall of the annular pipe and correspond to the first hole and the second hole respectively, a first slag discharging opening is formed in the outer wall of an annular notch, a third hole and a fourth hole are formed in the outer wall of a pump body, an arc-shaped outer sleeve is arranged on the pump body and wraps the pump body, and a second slag discharging opening is formed in the arc-shaped outer sleeve. Impurities are discharged in time through the first slag discharging port, the interior of the water inlet pipe is prevented from being blocked, impurities in a pump shell are discharged in time through the second slag discharging port, shutdown disassembly is not needed when the impurities are cleaned, the working time is saved, and the machining efficiency is improved.

Description

Technical field: [0001] The invention relates to the technical field of double-suction pumps, in particular to a double-suction pump capable of intercepting and discharging sundries. Background technique: [0002] As an important form of centrifugal pump, double-suction pump is widely used in engineering because of its high lift and large flow. The impeller of this type of pump is actually composed of two back-to-back impellers, and the water flow from the impeller is merged into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same outer diameter of the impeller; the pump casing is opened horizontally, which is convenient for inspection and maintenance. The inlet and outlet of the suction pump are in the same direction and perpendicular to the pump shaft, which is convenient for the arrangement and installation of th...
