What Are The Main Components Of A Hydraulic Powerpack?

Posted by VHS Hydraulic Components Ltd on July 14th, 2023

Before diving into the components and their contribution to the design of a hydraulic powerpack, let us understand what the structure actually indicates. A hydraulic powerpack is a large and durable hydraulic power unit that is built for functioning under a varied range of environmental conditions. The designs and characteristics of a Rexroth hydraulic powerpack also include a distinct and unique pumping system that is typical of these designs. The unit itself is capable of converting mechanical energy into hydraulic energy. Here are the main components of a hydraulic pump that play a major role in its overall functioning.

The lightweight gear pumps

Gear pumps are a major part of a Rexroth hydraulic that is built with a lightweight and compact design. Hydraulic units usually work with hydraulic gear pumps as the construction of this equipment is simple with easy fabrication. Using lightweight hydraulic gear pumps can also prove low on costs, and the compact size of the equipment makes them compatible with various models. A hydraulic gear pump also provides self-priming performance that implies that it is capable of evacuating air from the suction line to ensure that the liquid is drawn into the pump. This specific capability of the fluid pump merely requires the liquid to be filled in the cavity of the pump. It can also be filled in the body of the pump, and the process is carried out to commence the pumping process. Hydraulic pumps are not sensitive to the pollution in the oil, thereby allowing the machinery to work seamlessly and at a high speed.

The power-generating motors

The motor used in a hydraulic powerpack is considered to be the power unit of the machinery. It enables the conversion of electrical energy into mechanical energy. The process is carried out to generate a driving torque that helps the hydraulic power units become the very power source for the machinery. The hydraulic power units have common classifications of AC and DC motors. The AC motors include two poles, while the DC motors include four poles. The common parameters of these motors include a power rating that implies the maximum working power of the motor. The operating voltage is directly related to the speed and is also bifurcated into no-load speed with the unit of revolutions per minute. A single motor is capable of providing power to an entire hydraulic power unit.

The storage tanks and filters

The storage tanks are constructed in the Rexroth hydraulic powerpack to store sufficient fluid from the pipes to be drained into the tanks. The filters in the powerpack are ideally installed along with the tank. These filters are known to be self-contained by-pass units. Thus, they have their separate motor, pump and filtering apparatus. The filters used in the equipment can serve the purpose of filling or emptying the tank with the help of a multi-directional valve. These filters are easy to replace even when the power is working, thus, preventing downtime.
