Oil pump energy storage motor

What makes a good oil pump?

These pumps, capable of supplying oil even when the engine is switched off, are characterized by high voltage, high oil-pressure, high flow rate (100 V, 1 Mpa, 10 L/min) and 25% higher efficiency—ranking in the top tier of the industry—than equivalent products made by our competitors.

Are electric oil pumps compatible with conventional oil pumps?

Hybrid vehicles, electric vehicles and idling stop systems—these and other recent advances in fuel economy all share the same problem: incompatibility with conventional mechanical oil pumps. The solution comes in the shape of electric oil pumps. In 2013, Nidec Tosok launched their first electric oil pumps for hybrid vehicles.

What are the emerging trends in electric oil pumps?

Another emerging trend is the expansion of the applications of electric oil pumps to include clutch disengagement, cooling and lubrication etc. Electric oil pumps are also seeing increased use in large hybrid vehicles resulting in a rise in demand for larger pump models.

What is an energy-saving oil drilling rig?

Therefore, an energy-saving oil drilling rig is presented. The equipped power of this rig is only one third of a conventional drilling rig, and this rig can recover and reuse the potential energy which is released by the drill stem when lowered. This rig owns remarkable energy-saving effect.

What makes Nidec Tosok HV oil pumps different?

In addition to using high-efficiency brushless DC motors, Nidec Tosok's HV oil pumps are also equipped with inverters using original control software that makes sensor-less high-speed start-up possible. The pumps themselves are internal gear pumps with an improved bearing construction designed to minimize torque loss.

How are energy storage accumulators arranged?

One chamber is arranged to the energy storage accumulator for energy saving. Other chambers are flexibly connected to the pump ports for variable transmission ratios. Areas of multiple chambers are designed to permit a symmetric single-rod cylinder. Three modes are switched by solenoid valves to expand force-velocity capabilities.
