Please refer to the first and second figures. The turbulent flow through the flow path of the impeller 5 becomes; 1 force: the direction of the fuel 6 pump outlet 45 rounds In the middle, the flow direction of the body is 61, and the back is programmed into the body of the body, such as the axis direction 62, and flows through the gap between the inner diameter of the inner wall of the impeller 5 and the gap between the bearing 78 and the bearing 78. If the flow direction is 64, the most M369391 is in the flow direction of 65, returning to the impeller inlet. The circulating flow of this fluid is used to provide the heat required for the ceramic 'ceramic bearing lubrication and to take away the heat generated by the rotor; VIII—the permanent magnet pump The basic structure is that the horse-wound circle 831 of the transposition motor 8 provides the stator rotating magnetic field 'and interacts with the permanent magnet magnetic field of the motor rotor 7 to generate torque and rotation'. The driving method is different from the direct-synchronous movement of the outer rotor; Since the motor coil 831 is composed of an induction coil, this means The sense & coil requires a larger volume than the permanent magnet to generate sufficient magnetic flux, or, in contrast, the magnetic flux of the large motor rotor 7', so the structure of the motor rotor 7 must cooperate with the motor stator 83 to produce the wire; However, this also means that the fixed shaft 3 of the motor 8 must bear more centrifugal force load from the weight of the motor rotor 7. The load of these centrifugal forces comes from the residual unbalance of the motor rotor 7 itself, 'plus the hydraulic bearing when running The centrifugal force generated by the eccentricity of the lubrication gap; the conventional technology to support the motor fixed shaft 3 with the structural strength of the plastic part often needs to face the problem of insufficient structural strength, especially when the temperature is in the enthalpy; secondly, the new one of the plastic part and the ceramic piece The shape quantity alone will also greatly reduce the supporting force of the fixed shaft 3 or cause deformation. For example, the main supporting structural member of the double-sided supporting fixed shaft is the strength of the cantilever structure of the tripod 31' bipod 31 at high temperature. Will decrease the shaft eccentricity; regardless of the bilateral support fixed shaft 3 or the cantilever support fixed shaft 3, the rear cover 41 is fixed, and the other support structure of 3 The thickness of the rear cover 41 itself is thinner in the side cylindrical portion 412. The valley is deformed by the liquid temperature or pressure. Although the side cylindrical portion 412 has the inner ring of the motor stator, the deformation is still easily affected. The central axis of the back cover is positioned 'this is another reason for the eccentricity of the fixed shaft; when the temperature and pressure increase until the back cover is sufficiently deformed, the fixed shaft can no longer be tightly coupled with the tripod 31 and the shaft hole seat 413 and loosened. The other reason for the other age is that the plastic material is different from the heat-changing material of the ceramic material, which causes a gap between the fixed shaft 3 and the plastic material to make the fixed shaft 3 loose; 7 M369391 water-magnetic canned pump is driven by the drive, As long as the output of the handle motor 8 is within a reasonable range, or the output torque is within a reasonable range, it can be appropriately increased by more than the rated point; when operating at low speed, these deformations and core strength considerations There is no need to pay attention to the system, but when the running speed exceeds the Wei speed, the centrifugal force of the fixed shaft 3 will increase by the quadratic multiple of the speed ratio. In view of the above-mentioned Lipu operation requirements, the core problems that the solution must face for the application requirements of the high-corrosion process are as follows: (1) The problem of insufficient bonding strength of plastic and ceramic materials due to thermophysical properties 0 (2) The problem of the strength of plastic materials at high temperatures is reduced. (3) The problem that the centrifugal speed increases when the operating speed exceeds the rated speed. The solution to the above problems, the ship must be analyzed for the detailed reasons of each side of the problem, in order to achieve the purpose of completely solving the problem, the following is the analysis of the cause of the problem: (1) the strength of plastic materials · · the strength of many corrosion resistant materials can not Tao Jing material phase ^ ' Especially the temperature increase, the material touch is slightly lower, the miscellaneous is still good strength under the temperature increase, but its resistance is insufficient. (2) The problem of money shape of plastic materials: Many materials have poor heat-resistant deformation properties and cannot maintain close bonding with ceramic materials. (3) Two speeds away from the force problem · The mass of the motor rotor is large, and the clearance required for lubrication between the hydraulic bearing and the solid shaft will increase the burden of the centrifugal force of the fixed shaft, and the ratio of the force to the speed of the fixed shaft is 2 2 times is said to be large, and the fixed shaft must bear higher centrifugal force when the surface is operated above the 舣 speed. 1 Solving the above problems has been related to the proposed solution, in which: The British patent pre-existing bill No. GB2417981 is the county suspension galaxie shaft structure design, = the bottom of the rear sill is made of high-rigidity structural members and the fixed shaft-starting, The plastic is combined with the solid and the (4) support force. The special ship (4) is made of M369391 with high temperature resistance and high strength. 'But this material f can not meet the demand of high-corrosion liquid such as hydrogen acid. Because the patent's previous case examines the engine cooling water circulation, there is no problem of resistance to recording, but the application of the plastic material in the anti-corrosion process, the combination of the fixed shaft and the glue, and the combination of other metal parts and return In the way, it is impossible to completely seal the liquid that is still rotted; the second part of the back cover is not enough to meet the success or failure (four) displacement or # position.
