Description

Technical Field

[0001] The utility model relates to a fully enclosed electric-liquid integrated refrigerant and fluorine pump. Background Art

[0002] Data centers are the core of modern information technology infrastructure, housing numerous servers and storage devices that process, store, and transmit vast quantities of data. Servers are among the most critical components in a data center, responsible for running applications and services. Because servers generate significant heat when handling high-load tasks, heat dissipation is a crucial consideration in data center design and operations.

[0003] In new energy or data centers, it's necessary to transport easily vaporized media, such as Freon or other refrigerants. Refrigerants are easily vaporized, so pumping liquids requires complete sealing and leakage prevention. Furthermore, no metal powder can enter the medium during the process, as this can affect the refrigeration system's operation.

[0004] The refrigeration system generally adopts a structure in which the motor and pump are separated to transport the refrigerant medium. However, this structure is large in size and cannot meet the installation requirements of a miniaturized refrigeration system. It has poor practicality and also poses certain safety hazards. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology and provide a technical solution for a fully enclosed electro-hydraulic integrated refrigerant and fluorine pump, which can not only make the structure of the entire pump compact and meet the installation requirements of miniaturized refrigeration systems and the transportation requirements of refrigerant media, but also realize a fully enclosed connection between the pump and the motor, which is not easy to leak and prevents metal powder from falling into, thereby greatly improving the safety and reliability of the pump during use.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A fully enclosed electro-hydraulic integrated refrigerant and fluorine pump, comprising

[0008] impeller;

[0009] a rotor, which has magnetic poles embedded in it;

[0010] and coils;

[0011] Its characteristics are:

[0012] The impeller and the rotor are an integrally processed structure or a detachable connection structure. When the coil is energized, a magnetic field is generated. The magnetic poles are forced to rotate in the magnetic field, so that the rotor drives the impeller to rotate synchronously, thereby realizing stable transportation of the refrigerant. Through the design of the above structure, not only can the structure of the entire pump be compact, meeting the installation requirements of miniaturized refrigeration systems and the transportation requirements of refrigerant media, but also a fully enclosed connection between the pump and the motor can be achieved, which is not prone to leakage and prevents metal powder from falling in, greatly improving the safety and reliability of the pump during use.

[0013] Furthermore, a support ring is provided inside the rotor to support the magnetic poles and prevent the magnetic poles from being deformed, thereby improving the stability and reliability of the rotor during rotation.

[0014] Furthermore, it also includes fasteners, which pass through the rotor and the magnetic poles and are connected to the impeller, thereby realizing a detachable connection between the rotor and the impeller and meeting the installation requirements of pumps of different sizes.

[0015] Furthermore, it also includes a volute, a pump casing and a back cover. The back cover is connected to the volute through the pump casing. A cover plate is provided between the volute and the pump casing for limiting the impeller and the rotor. Through the design of the volute, pump casing, back cover and cover plate, the entire pump can be fully enclosed, which is not easy to cause leakage and can also prevent metal powder from falling in, thereby greatly improving the reliability of the pump during use.

[0016] Furthermore, the coil is connected to the pump housing, the cover plate and the rear cover via a support frame, and the support frame improves the stability of the coil installation.

[0017] Furthermore, the rotor and impeller are connected to the volute and the rear cover through a connecting shaft. Bushings are provided at both ends of the connecting shaft, and bearings are provided between the bushings and the rotor. The design of the above structure can lock the forward and backward movement distance of the rotor and impeller so that they will not move, which greatly improves the stability and reliability of the pump during operation, and at the same time can reduce noise and wear.

[0018] Furthermore, the bearing is a ceramic bearing or a wear-resistant bearing.

[0019] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0020] 1. The utility model can not only make the structure of the entire pump compact, meeting the installation requirements of miniaturized refrigeration systems and the transportation of refrigerant media, but also realize a fully enclosed connection between the pump and the motor, which is not prone to leakage and prevents metal powder from falling in, thereby greatly improving the safety and reliability of the pump when in use.

[0021] 2. A support ring is provided inside the rotor to support the magnetic poles and prevent them from deformation, thereby improving the stability and reliability of the rotor during rotation.

[0022] 3. A bearing is provided between the shaft sleeve and the rotor, which can lock the forward and backward movement distance of the rotor and impeller and prevent them from moving. This greatly improves the stability and reliability of the pump during operation, while reducing noise and wear. BRIEF DESCRIPTION OF THE DRAWINGS
