There are typically three types of hydraulic pump constructions found in mobile hydraulic applications.

Figures in the body of this table show the horsepower needed to drive a positive displacement hydraulic pump, and would be valid either for electric motor or engine drive.

What is a Hydraulic Pump and Why do You Need It?

With the right tools and expertise for challenges involving high pressure, high horsepower, low viscosity fluids, and water-based fluids, we have the solution for your application. Variable volume and pressure compensated design simplifies circuit design, reduces heat build-up and noise, and lowers horsepower requirements. PVX pumps are available with controls for standard pressure compensation, load sensing, remote pressure control, and horsepower limitation. The control options permit our machine design to utilize efficient controls tailored specifically to our customers' systems. Continental also offers variable volume, pressure compensated axial piston pumps, the HPV pump.

At the Bulle location in Switzerland, Liebherr has been manufacturing axial piston pumps and motors in swashplate design for more than 40 years. Development and production of the components is supported by decades of experience and stateof-the-art technologies. In order to meet the requirements of every customer optimally, the components can be put together flexibly and individually thanks to modular systems. Furthermore, the product range offers various application-specific options. Advantages Key factors for success such as durability and availability lead to high cost-effectiveness and The foundation for the quality and performance of Liebherr hydraulic components is laid right at the point of product development.

Hydraulics makes a flexible and efficient form of energy transfer. With the introduction of modern machinery the need to power them has driven innovations in hydraulic energy; hydraulic pump technology is often chosen for their efficiency and simple designs. So how does a hydraulic pump work?. It can be described as a device that converts a rotary or linear motion to hydraulic energy. The fluid when exists the pump it will have a higher velocity and pressure than at entry. It must be noted that the pump does not produce pressure, it only produces flow, it has the ability to do this at elevated pressures. Hydraulic pumps are used in a wide scope of engineering fields and are available in a variety of designs.

What are Hydraulic Motors?

Hydraulic pumps are sources of power for many dynamic machines. Hydraulic pumps are capable of pushing large amounts of oil through hydraulic cylinders or hydraulic motors. In this fashion, the pump converts the mechanical energy of the drive i. You can use hydraulic machines - equipped with a pump - to do different types of work such as lift, lower, open, close or rotate components. Hydraulic pumps operate according to the displacement principle. This involves the existence of mechanically sealed chambers in the pump. Through these chambers, fluid is transported from the inlet suction port of the pump to the outlet pressure port.


The PGP/PGM Series pumps and motors set the standard for superior performance and reliability in heavy-duty hydraulic application. The three-piece cast.

Hydraulic motors are rotary actuators that convert hydraulic, or fluid energy into mechanical power. They work in tandem with a hydraulic pump, which converts mechanical power into fluid, or hydraulic power. Hydraulic motors provide the force and supply the motion to move an external load. Three common types of hydraulic motors are used most often today—gear, vane and piston motors—with a variety of styles available among them. In addition, several other varieties exist that are less commonly used, including gerotor or gerolor orbital or roller star motors.

Я хотел лично сказать Росио, какое удовольствие получил от общения с ней несколько дней. Но я уезжаю сегодня вечером. Пожалуй, я все же оставлю ей записку.

Сьюзан словно во сне подошла и села с ним. - Сьюзан, - начал он, - я не был с тобой вполне откровенен. ГЛАВА 73 У Дэвида Беккера было такое ощущение, будто его лицо обдали скипидаром и подожгли. Он катался по полу и сквозь мутную пелену в глазах видел девушку, бегущую к вращающейся двери. Она бежала короткими испуганными прыжками, волоча по кафельному полу туристскую сумку. Беккер хотел подняться на ноги, но у него не было на это сил. Ослепленные глаза горели огнем.

 И что? - воскликнул Джабба.  - Человек Стратмора его нашел. Сьюзан, больше не в силах сдержать слезы, разрыдалась. - Да, - еле слышно сказала.  - Полагаю, что. ГЛАВА 111 В комнате оперативного управления раздался страшный крик Соши: - Акулы.

Да, это. Он - лжец. Он вел себя бесчестно по отношению ко многим людям, и Сьюзан Флетчер - одна из. Он очень о многом ей не сказал - о многих вещах, которых теперь стыдился. Она была его иллюзией, его живой фантазией.

Я все это видел, потому что прятался в подсобке.
