Description

Technical Field

[0001] The utility model relates to the technical field of circulating pumps, in particular to a linkage device for multiple circulating pumps. Background Art

[0002] A circulating pump refers to a circulating liquid pump used to transport reaction, absorption, separation, and absorption liquid regeneration in a device. It has a low head and is only used to overcome the pressure drop of the circulation system. A low-head pump can be used. A circulating pump refers to the function of the pump, while a centrifugal pump refers to the structure of the pump. The two are completely two different concepts. The working principle of a circulating pump The pump used to circulate water is called a circulating pump. For example, the hot water in the water heating pipe is circulated by a circulating pump. In large-scale industrial equipment, HVAC systems, water supply systems and other fields, multiple circulating pumps are often required to provide large flow or high-pressure liquid circulation. Traditional multiple circulating pump systems usually operate independently, and the working status and load distribution of the pumps mainly rely on manual adjustment by the operator, lacking automated and intelligent collaborative control.

[0003] However, there are some problems with traditional independent pump groups. First, load distribution and balancing require manual intervention and adjustment, which may lead to uneven load distribution and pump overload or idleness, reducing the efficiency and energy utilization of the system. Second, the circulating pump needs to be cooled when in use. The existing heat dissipation device is generally located inside the circulating pump, occupying more space inside the circulating pump, causing great inconvenience to the maintenance of the circulating pump. Therefore, a linkage device for multiple circulating pumps is proposed.

[0004] At present, the multiple circulation pump linkage devices on the market have the following disadvantages: 1. The circulation pump needs to be cooled when in use. The existing heat dissipation device is generally located inside the circulation pump, which occupies more space inside the circulation pump, causing great inconvenience to the maintenance of the circulation pump; 2. The load distribution and balance of the circulation pump require manual intervention and adjustment, which may lead to uneven load distribution and overload or idleness of the pump, reducing the efficiency and energy utilization of the system.

[0005] Therefore, it is necessary to invent a plurality of circulating pump linkage devices to solve the above problems. Utility Model Content
