Description

Technical Field

[0001] This utility model relates to the field of deep well centrifugal pump technology, and in particular to a deep well centrifugal pump venting efficiency enhancement device. Background Technology

[0002] Before starting, segmented horizontal multistage centrifugal pumps vent air to increase the vacuum level of the pump chamber and reduce cavitation on the pump body. Currently, the vacuum venting method for segmented horizontal multistage centrifugal pumps is to use a bottomless valve filling method.

[0003] The current vacuum purging method cannot completely remove air from the pump cavity in both local and in-system control modes. It requires manually opening the vent valve at the top of the pump body to remove air, and the purging process is time-consuming, failing to meet the purging requirements of various control modes. Therefore, this invention proposes a deep well centrifugal pump purging efficiency enhancement device to address the shortcomings of the existing technology. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a deep well centrifugal pump venting efficiency enhancement device. This device involves installing a pipe connector within a threaded hole at the top of the deep well centrifugal pump's inlet end. A first galvanized pipe assembly and a second galvanized pipe assembly are then installed at one end of the pipe connector. An electromagnetic control valve is installed on the second galvanized pipe assembly, connected in series with the vent valve of the deep well centrifugal pump's bottomless venting device. When the vent valve of the bottomless venting device is opened, the electromagnetic control valve opens simultaneously to assist the bottomless venting device in venting. Because the venting efficiency enhancement device is located at the top of the deep well centrifugal pump's inlet end, it can completely expel air from the pump under the pressure of the filling water.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A deep well centrifugal pump venting efficiency enhancement device includes a pipe connector, a first galvanized pipe assembly, a second galvanized pipe assembly, a purification tank, and an electromagnetic control valve. The pipe connector is connected to a threaded hole at the top of the water inlet of the deep well centrifugal pump. The pipe connector is equipped with a shut-off valve. The first galvanized pipe assembly is detachably connected to the pipe connector. One end of the first galvanized pipe assembly is connected to the input end of the purification tank. The output end of the purification tank is equipped with a second galvanized pipe assembly. The second galvanized pipe assembly is equipped with an electromagnetic control valve. The electromagnetic control valve is connected in series with the vent valve of the bottomless venting device of the deep well centrifugal pump. The purification box includes a box body, a box cover, and an activated carbon filter plate. The top of the box body is open and can be fitted with a box cover. The bottom of the box cover is provided with an activated carbon filter plate, and the activated carbon filter plate is provided in multiple sets.

[0006] A further improvement is that the first galvanized pipe group and the second galvanized pipe group have the same structure, both including galvanized single pipes and pipe joints. The first galvanized pipe group and the second galvanized pipe group are composed of at least two groups of galvanized single pipes, and adjacent galvanized single pipes are connected by pipe joints.

[0007] A further improvement is that: both the output end and the output end of the enclosure are provided with a first flange plate, and one end of the galvanized single pipe at the connection between the first galvanized pipe group and the second galvanized pipe group and the output end of the enclosure is provided with a second flange plate, and the first flange plate and the second flange plate are connected by bolts and nuts.

[0008] A further improvement is that connecting bolts are provided at the four corners of the top of the box cover, and the box cover is connected to the top of the box body through the connecting bolts.

[0009] A further improvement is that: the bottom of the box cover is provided with a T-shaped positioning groove, and the top of the activated carbon filter plate is provided with a T-shaped positioning block that matches the T-shaped positioning groove; the activated carbon filter plate is movably installed through the T-shaped positioning block and the T-shaped positioning groove.

[0010] A further improvement is that the size of the activated carbon filter plate is adapted to the internal cross-sectional dimensions of the housing.

[0011] A further improvement is that: the back of the box is symmetrically provided with L-shaped fixing rods, and the L-shaped fixing rods are provided with fixing holes.

[0012] The beneficial effects of this utility model are as follows: This utility model sets a pipe connector in the threaded hole at the top of the water inlet of the deep well centrifugal pump, and then sets a first galvanized pipe group and a second galvanized pipe group at one end of the pipe connector. An electromagnetic control valve is set on the second galvanized pipe group and connected in series with the vent valve of the bottomless venting device of the deep well centrifugal pump. When the vent valve of the bottomless venting device is opened, the electromagnetic control valve opens synchronously to assist the bottomless venting device in venting. Since the venting efficiency enhancement device is set at the top of the water inlet of the deep well centrifugal pump in this utility model, it can completely remove the air in the pump under the pressure of the filling water. The first galvanized pipe assembly and the second galvanized pipe assembly of this utility model are connected by a purification box. Through multiple sets of activated carbon filter plates, the air and water during the venting process can be filtered to prevent harmful substances in the air and water from entering the subsequent pipelines and causing corrosion problems. This can improve the operational stability of the venting efficiency enhancement device of this utility model and increase its service life. Attached Figure Description
