Embodiment Construction
[0025] The features and principles of the present invention will be described in detail below with reference to the accompanying drawings. The examples are only used to explain the present invention, and are not intended to limit the protection scope of the present invention.
[0026] like Figure 1 to Figure 6 As shown, a permanent magnet direct drive slurry pump with a water cooling circulation structure includes a pump body, a permanent magnet synchronous motor, a water inlet pipe 17 , a water outlet pipe 18 , a base 28 and a cooling water tank 29 .
[0027] like figure 1 As shown, the pump body and the permanent magnet synchronous motor are connected through the shaft 8 and fixedly mounted on the base 28 . The permanent magnet synchronous motor and the slurry pump have an integrated structure, and they share one shaft, eliminating the need for a coupling and a reducer, thereby avoiding the adverse effects of high temperature on the coupling and bearing box during continuo...

A permanent magnet direct-drive slurry pump with a water-cooled circulation structure, including a pump body, a permanent magnet synchronous motor, and a cooling water tank. The pump body is directly connected to the permanent magnet synchronous motor and shares a shaft; the permanent magnet synchronous motor The motor also includes a built-in coolant drive device, the built-in coolant drive device is installed in the motor housing of the permanent magnet synchronous motor, and the cooling water tank forms a cooling cycle with the built-in coolant drive device and the coolant channel provided with the motor housing aisle. The disadvantages of the existing slurry pump such as complex structure, low transmission efficiency and high energy consumption are solved, and the purpose of water cooling cycle of the driving motor is realized, and the structure has the function of assisting to offset the axial force.
Description
technical field [0001] The invention relates to the technical field of slurry pumps, in particular to a permanent magnet direct-drive slurry pump with a water-cooled circulation structure. Background technique [0002] As a special centrifugal pump for transporting solid-liquid mixture, slurry pump is widely used in coal mine, petrochemical, electric power, metallurgy and building materials and other industries. At present, the commonly used slurry pump is driven by an intermediate transmission device such as a motor, a coupling or a pulley, which has the disadvantages of complex structure, large volume, low efficiency and high energy consumption. The permanent magnet synchronous motor is used to directly drive the load, which avoids the shortcomings of the traditional driving method and greatly improves the mechanical transmission efficiency. At present, permanent magnet direct drive systems are mainly used in technical fields such as wind power generation and mine materia...
