Description

Technical Field

[0001] The invention relates to a water pump suction pipe auxiliary device. Background Art

[0002] In industrial circulating water treatment processes, water pumps are common water transport equipment. Their safe and stable operation directly impacts industrial production efficiency. In environments with long suction pipes, there are two potential issues: pipe blockage and the need to vent the pump before starting. These issues seriously impact pump operation. Therefore, the invention of a pump operation assist device is necessary to address the risk of suction pipe blockage and reduce the time required to vent the pump before starting. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and propose a water pump suction pipe auxiliary device, which can solve the problem of water pump impeller blockage caused by debris in the suction pipe, increase the service life of the water pump, reduce the frequency of routine maintenance operations, and eliminate the exhaust operation before starting the water pump.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A water pump suction pipe auxiliary device includes a box body, a water inlet is provided on one side of the box body, and a suction pipe is connected through the water inlet, a water outlet is provided on the other side of the box body, a pump water inlet pipe is provided in the water outlet, and the inlet end of the pump water inlet pipe extends into the box body, a filter assembly is provided perpendicular to the water inlet and the water outlet, and the filter assembly is detachably connected to the box body.

[0005] The present invention further defines the technical solution: Preferably, a connecting flange is provided on the top of the box body, which can be connected to a blind plate for sealing.

[0006] Preferably, the inlet end of the pump water inlet pipe is located at the bottom end of the box body.

[0007] Preferably, limiting grooves are provided on the inner walls of both sides of the box body, and both sides of the filter assembly are respectively located in the limiting grooves at the corresponding ends and are fixedly connected by bolts.

[0008] Preferably, the filter assembly consists of at least two filter screens, and the four sides of each filter screen are sealed. A groove is provided at the bottom of the upper filter screen, and the groove is connected to the block provided at the top of the lower filter screen. A single filter screen can be replaced according to the situation without replacing the entire filter screen.

[0009] Preferably, the filter screen is made of stainless steel.

[0010] Preferably, an exhaust valve is provided on one side of the top of the box body.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention has a simple structure. A filter assembly is provided perpendicular to the water inlet and the water outlet, which can filter out debris, avoid clogging of the water pump impeller, increase the service life of the water pump, and reduce the frequency of routine maintenance operations. At the same time, since the inlet end of the pump water inlet pipe is located at the bottom end of the box body, when the water pump stops, the water inside the box body will not flow back to the pool. When the water pump starts, the water source inside the box body is sufficient to start the water pump. At the same time, since the water source inside the box is sucked out, the negative pressure in the box body sucks the water source on the pool side into the device, forming a circulation, and avoiding exhaust operation when starting the pump.

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0014] Reference Figure 1 , a water pump suction pipe auxiliary device, including a box body 1, a connecting flange 2 is provided on the top of the box body, which can be connected to a blind plate for sealing, and an exhaust valve is provided on one side of the top of the box body, a water inlet is provided on one side of the box body, and a suction pipe 3 is connected through the water inlet, and a water outlet is provided on the other side of the box body, a pump water inlet pipe 4 is provided in the water outlet, and the inlet end of the pump water inlet pipe extends into the box body, and the inlet end of the pump water inlet pipe is located at the bottom end of the box body, and a filter assembly 5 perpendicular to the water inlet is provided between the water inlet and the water outlet, and limiting grooves are provided on the inner walls on both sides of the box body, and the two sides of the filter assembly are respectively located in the limiting grooves at the corresponding ends and are fixedly connected by bolts; The filter assembly consists of two stainless steel filter screens. The four sides of each filter screen are sealed. A groove is set at the bottom of the upper filter screen, and the groove is connected to the block set at the top of the lower filter screen. You can replace a single filter screen according to the situation without replacing the entire filter screen.

[0015] This embodiment has a simple structure. A filter assembly is provided perpendicular to the water inlet and the water outlet, which can filter out debris, avoid clogging of the water pump impeller, increase the service life of the water pump, and reduce the frequency of routine maintenance operations. At the same time, since the inlet end of the pump water inlet pipe is located at the bottom end of the box body, when the water pump stops, the water inside the box body will not flow back to the pool. When the water pump starts, the water source inside the box body is sufficient to start the water pump. At the same time, since the water source inside the box is sucked out, the negative pressure in the box body will suck the water source on the pool side into the device, forming a cycle, thereby avoiding exhaust operation when starting the pump.
