Product Overview

BREVINI is a well - known enterprise in the fields of transmission and hydraulics. The S6CV128BHS27 -RD505519/2 hydraulic pump produced by it is one of the hydraulic products in the brand's series. This hydraulic pump is designed to meet the complex hydraulic system requirements of various industrial and mobile equipment, providing stable and efficient hydraulic power to ensure the normal operation of the equipment.

Technical Parameters

• Displacement: Depending on different working conditions and applications, this pump may have a specific displacement range. It determines the volume of hydraulic oil output by the pump per unit time, directly affecting the flow rate of the system and the movement speed of the actuators. For example, in some small - and medium - sized equipment, the displacement may be at a relatively moderate value to meet the basic operational requirements of the equipment. In large - scale, high - load equipment, the displacement may be larger to provide sufficient flow to drive multiple actuators simultaneously.

• Pressure Ratings:

• Rated Pressure: It refers to the pressure value that the hydraulic pump can output steadily over a long period under normal working conditions. The rated pressure of this pump ensures that the system can obtain reliable power support during regular operation, allowing all components of the equipment to work as designed.

• Maximum Pressure: It is the instantaneous maximum pressure that the hydraulic pump can withstand. In special situations such as equipment startup and sudden load increases, the system pressure may rise briefly. At this time, the hydraulic pump needs to be able to operate safely within the maximum pressure range to avoid damage due to excessive pressure.

• Speed Range: It specifies the rotational speed interval within which the hydraulic pump can operate normally. An appropriate speed range is crucial for the performance and service life of the pump. A speed that is too low may result in insufficient output flow of the pump, affecting the working efficiency of the system. A speed that is too high may cause increased wear of the internal components of the pump, severe heating, and other problems, shortening the service life of the pump.

• Power Requirements: Based on parameters such as the displacement, pressure, and speed of the pump, the required input power can be determined. This parameter is of great significance for selecting an appropriate driving motor or engine, ensuring that the driving device can provide sufficient power for the hydraulic pump while avoiding power waste or insufficiency.

Structural Features

• Compact Design: By adopting advanced design concepts and manufacturing processes, the hydraulic pump minimizes its volume and weight while ensuring performance. This is particularly important for equipment with limited space, such as mobile construction machinery and aerospace equipment, as it saves installation space and improves the overall layout rationality of the equipment.

• High Efficiency: Through optimizing the internal flow channel design of the pump and reducing friction losses, the volumetric efficiency and mechanical efficiency of the pump are improved. An efficient hydraulic pump can output more hydraulic energy under the same input power, reducing energy losses and improving the overall efficiency of the system, thus saving energy costs for users.

• High Reliability: High - quality materials and advanced processing techniques are used to manufacture key components, ensuring that the pump can operate stably under various harsh working conditions. For example, the gears and shafts of the pump are precisely machined and heat - treated, having good wear resistance and fatigue resistance. High - performance sealing materials are used for the seals, which can effectively prevent hydraulic oil leakage and ensure the sealing and reliability of the system.

• Easy Maintenance: The design takes into account the convenience of maintenance. For example, a detachable structural design is adopted, allowing for quick and easy operation when repairs or component replacements are required. At the same time, each component of the pump is clearly labeled, facilitating identification and installation by maintenance personnel and reducing maintenance time and costs.

Application Areas

• Construction Machinery: It is widely used in various construction machinery such as excavators, loaders, and cranes. In excavators, this hydraulic pump provides hydraulic power for actuators such as the boom, stick, and bucket, enabling actions such as excavation, lifting, and swinging. In loaders, it is used to drive operations such as the lifting and tilting of the working device. In cranes, it supplies power for mechanisms such as hoisting, luffing, and slewing to ensure the smooth progress of lifting operations.

• Agricultural Machinery: It is also applied in agricultural machinery such as tractors and combine harvesters. In tractors, the hydraulic pump provides hydraulic power for the hitch system and power take - off shaft, enabling the lifting and lowering of farm implements and power transmission. In combine harvesters, it is used to drive key components such as the header lifting and threshing drum rotation, improving harvesting efficiency and quality.

• Industrial Equipment: It is suitable for industrial equipment such as injection molding machines, die - casting machines, and machine tools. In injection molding machines, the hydraulic pump provides high - pressure hydraulic oil for the clamping mechanism and injection mechanism to achieve the molding of plastic products. In die - casting machines, it is used to drive the injection mechanism to inject molten metal into the mold cavity. In machine tools, it supplies power for the feed system and spindle system to ensure the machining accuracy and efficiency of the machine tool.

• Marine and Ocean Engineering: It is used in equipment such as ship steering gears and deck machinery. The steering gear relies on the hydraulic power provided by the hydraulic pump to achieve the steering operation of the ship, ensuring the navigation safety of the ship. Deck machinery such as anchors and winches also require the hydraulic pump to provide power for operations such as anchor raising and mooring.

• Regular Maintenance:

• Component Replacement: Replace wearing parts such as seals and bearings according to the requirements of the equipment maintenance manual. These parts will gradually wear out after long - term use, affecting the performance and sealing of the pump. Timely replacement can ensure the normal operation of the pump.

• Cleaning and Inspection: Regularly clean the hydraulic pump to remove dirt and impurities inside. At the same time, check whether each component of the pump has defects such as wear or cracks. If any problems are found, they should be repaired or replaced in a timely manner.

• Parameter Adjustment: According to the actual usage and requirements of the equipment, adjust parameters such as the pressure and flow rate of the hydraulic pump in a timely manner to ensure that the pump always operates in the optimal state.

Maintenance and Upkeep

• Daily Inspection:

• Hydraulic Oil Inspection: Regularly check the oil level and quality of the hydraulic oil. A low oil level may cause insufficient oil suction of the pump, resulting in cavitation and damage to the internal components of the pump. Poor oil quality (such as containing impurities or excessive moisture) will affect the performance and service life of the pump. Therefore, the hydraulic oil should be replaced according to the specified cycle, and a filter element that meets the requirements should be used for filtration.

• Leakage Inspection: Check whether there is any leakage in the hydraulic pump and the connecting pipelines. Leakage not only wastes hydraulic oil but also reduces the system pressure, affecting the normal operation of the equipment. Any leakage found should be dealt with promptly, and damaged seals should be replaced or loose connectors should be tightened.

• Noise and Vibration Inspection: Pay attention to whether there is any abnormal noise during the operation of the hydraulic pump and observe whether there is any abnormal vibration. Abnormal noise and vibration may be signs of faults such as wear, looseness, or cavitation of the internal components of the pump. The equipment should be stopped immediately for inspection, and the fault should be eliminated.
