The invention relates to a hydraulic pump unit comprising a hydrostatic system pump which is used to provide a hydraulic working system with hydraulic fluid via a pressure connection, also comprising a second pump which is used to suction hydraulic fluid via an inlet and feed said fluid to a low pressure area of the system pump, further comprising an electric motor provided with an outer casing and which is used to drive both pumps. The aim of the invention is to provide a hydraulic pump unit enabling power losses to be kept to a minimum and which can be permanently operated without causing the temperature of the hydraulic fluid to rise to values resulting in increased leakage or rapid ageing of the hydraulic fluid. To achieve this aim, the system pump is an especially pressure-regulated variable displacement pump and the hydraulic fluid can be pumped by the second pump into a return opening in such a way that it by-passes the system during circulation from the inlet via a cooling circuit ...

The fan radiator 3 is mounted between the motor body 1 and the controller 2 to disperse heat from the motor body 1 and the controller 2. The brushless DC motor structure increases air flow on the surface of the motor body 1 and the controller 2 by the fan radiator 3 and speeds up heat dispersion, and meanwhile effectively controls the operating temperature of the motor body 1 and the controller 2. Thus, the brushless DC motor structure has an excellent heat dispersion effect, and failure rate has been largely reduced.

FAN SHROUD AND MOTOR ASSEMBLY COMPRISED THEREOF

Номер: CA0002844990A1
Принадлежит:

This disclosure proposes designs for a fan shroud that dissipates thermal energy from a motor using a single, externally-powered fan design. Examples of the proposed fan shroud allow the cooling fluid to achieve maximum velocity at a position at which the fan shroud exposes the flow to cooler ambient air that surrounds the fan shroud/motor assembly. In this configuration, the high-velocity cooling fluid draws the cooler ambient air towards the surface of the motor, which, in turn, increases the thermal capacity of the moving cooling fluid to dissipate more thermal energy from the motor.

DRY-PIT SUBMERSIBLE PUMP AND LIQUID TRANSFER METHOD

Номер: CA0002248849C

A dry-pit submersible pump using a totally enclosed fan-cooled (TEFC) electric motor to power the pump. A release mechanism prevents the fan from creating excessive drag when submerged in water. The fan cools the motor when the wat er level is below the motor, and the surrounding water combines with the fan to cool the motor when the water level rises to at least partially surround the motor. When the fan is at least partially submerged, the release mechanism substantially prevents the fan from imposin g a load on the motor due to the surrounding water. The release mechanism can take the form of a shear key, a torque-release clutch or flexible fan blades.

The cooling fan is mounted at the rotating shaft for generating airflow towards the cylindrical housing for dissipating the heat generated in the motor. The hollow hood is mounted to the cylindrical housing such that a head portion is located above the upstream through hole, thus defining an annular air-guiding channel therebetween, which can receive the airflow generated by the cooling fan and guide the airflow to enter the cylindrical housing via the upstream through holes, so that the heat generated therein can be dissipated effectively. Thus, heat is not easy to accumulate in the motor, and the performance and service life of the motor can be increased.

A machine such as a ship's engine has a superconducting component 15 requiring cooling for its operation, and includes a cooling system 40 . The cooling system is operable in first and second modes. In a cool-down phase the cooling system is run in the first mode providing relatively high heat transfer from the superconducting component. On attainment of a desired operating temperature the cooling system is run in the second mode, providing lower heat transfer. This enables a reduced cool-down time of the machine, while allowing economical operation in normal service. The higher level of cooling in the first mode used during the start-up procedure can involve a colder cryogen, or a greater flow of coolant. One way of achieving the latter is to circulate the coolant in normally evacuated regions 16 during the cool-down phase, and then re-establishing the vacuum in these regions for normal service operation.

A motor includes a substantially cylindrical housing, a rotor assembly, a cover, a sleeve, and a cooling fan. The cooling fan is installed at one end of a rotating shaft of the rotor assembly to induce airflow. The sleeve, being closely fitted around the housing, is integrally formed with a plurality of wind-caching projections, each of which is located above one upstream through hole defined on the housing and faces towards the cooling fan. The wind-catching projections can receive the airflow induced by the cooling fan and guides the airflow to enter the housing via the upstream through holes to dissipate the heat accumulated in the motor, so that the motor can be prevented from damages due to heat accumulation. Therefore, the performance and service life of the motor can be increased.
