Hydraulic pumps in the energy and environmental protection fields

Series and Specifications/Models of Hydraulic Pumps for Energy and Environmental Protection Fields

Hydraulic pumps are the core power components of hydraulic systems in the energy and environmental protection fields, mainly used in renewable energy power generation (solar, wind, geothermal), sewage treatment, solid waste disposal, energy-saving equipment and other scenarios. They are responsible for converting mechanical energy into hydraulic energy, ensuring efficient, energy-saving and stable operation of related equipment. According to the working principle, structural characteristics and application requirements, the commonly used hydraulic pumps in energy and environmental protection fields are mainly divided into three major series: gear pump series, vane pump series and piston pump series. Each series has corresponding specifications and models, which are clearly distinguished by core parameters such as displacement, pressure rating, energy efficiency level and installation type, meeting the diverse needs of different environmental protection and energy projects.

1. Gear Pump Series (Gear Pumps) for Energy and Environmental Protection

Gear pumps are widely used in medium and low-pressure hydraulic systems in the energy and environmental protection fields due to their simple structure, reliable operation, low energy consumption and low maintenance cost. They are mainly used in small and medium-sized environmental protection equipment and auxiliary energy systems, such as sewage lifting pumps, small solar auxiliary hydraulic systems and solid waste sorting equipment. They are divided into external gear pumps and internal gear pumps, with external gear pumps being more widely used.

1.1 Common Series and Specifications

  • External Gear Pump Series: CB series, CBN series, CBG series, etc. These series are suitable for low-pressure, high-flow energy-saving scenarios, such as sewage treatment equipment (sewage lifting, sludge transportation) and small wind power auxiliary systems. The specifications are mainly distinguished by displacement (unit: mL/r), pressure rating (unit: MPa) and energy efficiency level.

4. Key Notes on Specifications and Models (for Search Optimization)

For hydraulic pumps in the energy and environmental protection fields, the specification and model usually include core information: series code (indicating pump type and structure), displacement (determining flow rate), pressure rating (adapting to working pressure requirements), energy efficiency level (meeting environmental protection and energy saving standards), installation type (flange, foot installation) and control mode (for variable pumps). When selecting, it is necessary to match the working conditions of energy and environmental protection projects (such as medium pressure/low pressure, high temperature/resistant to corrosion, energy saving requirements) to ensure efficient, energy-saving and stable operation of the system. The above series and models are the most commonly used in the industry, covering most application scenarios of renewable energy power generation and environmental protection equipment.
