Description

Technical Field

[0001] This utility model relates to the field of vacuum circulating water pumps, and in particular to vacuum circulating water pumps. Background Technology

[0002] Vacuum circulating water pumps, also known as water ring vacuum pumps, are a type of vacuum pump that uses water as the working fluid. Their working principle is based on that of liquid ring pumps, mainly using the circulating flow of water to extract gas and create a vacuum environment. Due to their high efficiency and economy, vacuum circulating water pumps have been widely used in many industries and are an indispensable piece of equipment in laboratories and industrial production.

[0003] Vacuum circulating water pumps are currently widely used. However, during use, the internal components of vacuum circulating water pumps are prone to blockage due to particles in the water, which affects their operation and requires improvement. Therefore, we propose a vacuum circulating water pump to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum circulating water pump to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vacuum circulating water pump includes a fixed plate, a pump body fixedly connected to the upper surface of the fixed plate, a connector fixedly connected to the output end of the pump body, a connecting pipe fixedly connected to the input end of the pump body, a limit ring fixedly connected to the inner wall of the connecting pipe, a threaded rod fixedly connected to the front of the limit ring, a filter screen provided in front of the connecting pipe, a sleeve fixedly embedded in the front of the filter screen, a pressure ring provided in front of the filter screen, two connecting rods fixedly connected to the front of the pressure ring, a push plate fixedly connected to the front ends of the two connecting rods, a through hole provided in the front of the push plate, a locking nut provided in front of the push plate, and a vertical plate fixedly connected to the upper surface of the fixed plate, the upper surface of the vertical plate being fixedly connected to the outer surface of the connecting pipe.

[0007] In a further embodiment, the upper surface of the fixing plate is provided with two sets of circular holes, and the inner wall of each circular hole is provided with threads.

[0008] In a further embodiment, a protective ring is provided in front of the filter screen, and the front of the protective ring is fixedly connected to the back of the pressure ring.

[0009] In a further embodiment, a fixing ring is fixedly connected to the outer surface of the connector, and a support plate is fixedly connected to the outer surface of the fixing ring. The bottom surface of the support plate is fixedly connected to the upper surface of the fixing plate.

[0010] In a further embodiment, a warning sign is provided above the fixing plate, and the back of the warning sign is fixedly connected to the outer surface of the pump body.

[0011] In a further embodiment, a bracket is fixedly connected to the upper surface of the fixing plate, and an anti-slip handle is fixedly connected to the upper surface of the bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, through the design of the limiting ring, can limit the operation of the filter screen. At the same time, the design of the locking nut, push plate, through hole, connecting rod and pressure ring makes it easy for the push plate to be pushed by the locking nut when the locking nut is threadedly connected to the threaded rod. This helps to push the connecting rod and pressure ring closer to the filter screen, and facilitates the installation, positioning and replacement of the filter screen. Subsequently, the design of the filter screen is conducive to filtering particulate matter in the water and can prevent the pump body from becoming blocked. Attached Figure Description

At this time, the filter screen 11 is in contact with the limiting ring 16. Next, the push plate 19 drives the pressure ring 10 to be put on the outside of the threaded rod 15. At this time, the threaded rod 15 passes through the through hole 20, and the locking nut 3 is threadedly connected to the threaded rod 15. Then, while the locking nut 3 rotates, it pushes the push plate 19 to move. At the same time, the thrust provided by the push plate 19 causes the pressure ring 10 to drive the protective ring 17 to position the filter screen 11. Then, through the design of the filter screen 11, particles in the water can be filtered.
