摘要： The invention relates to a magnetic coupling pump, with the motor-driven part of the magnetic coupling lying radially inward and the radially outward part of the coupling, together with the pump rotor, having a floating fit in the pumped fluid such that the rotating part of the floating bearing is also radially arranged over the outer magnets. The wall of the pump housing can itself be embodied as the stationary part of the floating bearing with the possibility of direct external access (lubrication, sensor mechanism) and an effective convectional cooling. Dry running on operational faults can be avoided by means of the floating bearing arranged far to the outside, as the damaging gas fraction collects in the radial interior of the pump and remaining traces of liquid are continuously driven outwards and thus contribute to bearing lubrication. By means of an additional annular barrier, the loss of residual fluid can be prevented. The disclosed novel floating bearing permits a large volume separating case which itself permits components of the roller bearings of the motor-driven magnetic coupling section so much installation space that the axial installation length of the complete pump can be significantly shortened.
摘要翻译：本发明涉及一种磁耦合泵，其中磁耦合的电机驱动部分径向向内并且联接器的径向向外部分与泵转子一起在泵送流体中具有浮动配合，使得旋转部分的浮动轴承也径向布置在外磁体上。泵壳的壁本身可以实现为浮动轴承的固定部分，具有直接外部进入（润滑，传感器机构）和有效的对流冷却的可能性。由于损坏的气体馏分收集在泵的径向内部，剩余的液体痕迹被连续地向外驱动，从而有助于轴承润滑，因此可以通过浮动轴承远离外部的方式避免运行故障。通过附加的环形阻挡件，可以防止残留流体的损失。所公开的新型浮动轴承允许大体积的分离箱，其本身允许电动机驱动磁耦合部分的滚子轴承的部件具有如此大的安装空间，从而可以显着缩短整个泵的轴向安装长度。

摘要： It is sought to provide a rear casing arrangement for a magnetic drive pump, which can sufficiently provide such functions pressure resistance and heat resistance, which give rise to problems in the case of manufacturing the rear casing from a material based on a synthetic resin, and can also be manufactured at low cost.A reinforcing belt-like ring member is woundly fitted on the outer periphery of a cylindrical barrel part of an inner casing member constituting a rear casing. The belt-like ring member has a width smaller than the length of the barrel part. A casing cover member is fitted on the belt-like ring member in the above fitted state. Alternatively, it is possible to fit the belt-like ring member on the outer periphery of a barrel part of the casing cover member. These parts can be disassembled.

摘要： A magnetically driven centrifugal pump includes a sealed housing enclosing a magnetically driven rotor on an axle of rotation contained within the housing, the axle being attached to the back inside wall of the housing and extending therefrom into the rotor, the rotor having impellers attached to the face thereof toward the front of the housing, the impellers defining radial fluid passages leading from the axial center of the front of the housing to the periphery of the housing and the rotor having radially oriented magnets in the back face thereof for coupling with similarly oriented magnets in an external magnetic drive, whereby the axial dimension of the rotor need be only the width of a radial magnet plus the axial projection of an impeller and the axial dimension of the sealed housing may be only slightly greater than the axial dimension of the rotor and may be substantially less than the radial diameter thereof. In operation, fluid enters an axial input port at the front of the housing and discharges from an output port at the periphery of the housing and the external magnetic drive magnetically couples with the rotor through the back wall of the housing. In a preferred embodiment, the impellers are radially extending ridges on the front face of the rotor and a disk-shaped plate attaches to and covers the impellers defining each radial passage between adjacent ridges, the face of the rotor and the covering plate.

摘要： A canned motor pump wherein the can has two coaxial tubular walls defining an annular space for the flow of a heat exchange fluid which heats or cools the can. If the can has an end wall, the latter can be formed with an additional space which communicates with the annular space. The driven rotor within the can can be rotated by a stator which surrounds the can or by a hollow rotor which rotates the driven rotor by way of one or more magnets. The can can be heated by an electric heater.

摘要： A magnetic pump drive comprises an isolating shell which is structured in the form of a stepped cylinder having at least one step for creating at least two cylindrical sections of different diameters. The efficiency of the power transmission of a driver carrying permanent magnets through the isolating shell onto a rotor also carrying permanent magnets is maintained in comparison with the efficiency of known devices, but the strength and form stability of the isolating shell is drastically improved. The strength against high system pressures is based on the steps which may comprise slipped-over rings or comprise integral reinforcement rings which act like barrel hoops.

摘要： A canned motor pump wherein the can has at least two coaxial tubular walls defining an annular space for the flow of a preferably gaseous fluid which is used to facilitate detection of leaks in the walls of the can. Each tubular wall can individually seal the driving unit from the driven unit of the pump motor. The leak detector can generate visible, audible and/or otherwise detectable signals, and such signals can also serve to stop the motor in the event of leakage.

摘要： A communication hole is bored through a partition member which divides an intake-side priming fluid chamber from a discharge-side priming fluid chamber, whereby the two chambers are connected. The communication hole serves to prevent, on a predetermined level, a backflow of a pump fluid due to siphonage caused on the intake side when pumping operation is stopped, thereby securing a priming fluid in a pump casing. A valve assembly including a valve member is disposed corresponding to the communication hole. The valve member, which is always urged to an open position, is moved to and held in a position where it is caused to close the communication hole by the action of the pump fluid flowing in a feeding direction during pumping operation. When the pump is stopped to cause the backflow of the fluid, the valve member is moved back to the open position by the urging action.

摘要： A magnetic drive pump for use as a vehicle coolant pump. A fluid housing fixed to the engine block as an impeller mounted on the outside of a cylindrical support integrally stamped into a front wall of the housing. A pulley has a central hub that is rotatably mounted within the cylindrical support, coaxial with the impeller bearing. A web of the pulley and the impeller both face the housing front wall in closely spaced, parallel relation, with opposed matching magnetic drive elements. The structure is particularly simple and compact, and needs no cartridge or bearing seal.
