2 month ago
Product details
the content about the **50T LR Hydraulic Vane Pump**:
1. Model Number Interpretation (Speculative)**
- **50T**: Likely denotes displacement (e.g., 50 cc/rev) or a series code.
- **LR**: May indicate "Low Pressure," "Long Reliability," or a manufacturer-specific series code (e.g., brands like Rexroth or Vickers often use letter combinations for product lines).
2. Typical Features of Hydraulic Vane Pumps**
- **Working Principle**:
Rotating vanes extend and retract in an eccentric rotor, creating sealed chambers to draw in and discharge oil, ensuring smooth flow output.
- **Advantages**:
- Low noise, minimal flow pulsation
- Suitable for medium-to-low pressure systems (typical range: 7–21 MPa)
- Compact design, low maintenance costs
3. Possible Performance Parameters for 50T LR (Example)**
| Parameter | Typical Value |
|------------------|-------------------------|
| Displacement | 50 cc/rev (to confirm) |
| Rated Pressure | 14–17 MPa (design-dependent)|
| Speed Range | 600–1800 RPM |
| Fluid | Mineral hydraulic oil (ISO VG32–68)|
| Connection | SAE flange or custom shaft end|
4. Common Applications**
- **Industrial Machinery**: Injection molding machines, machine tool hydraulic systems, automated production lines.
- **Mobile Equipment**: Steering or auxiliary systems in agricultural or compact construction machinery.
- **Low-Pressure Lubrication Systems**: Centralized oil supply or cooling circulation systems.
5. Selection and Maintenance Tips**
- **Key Selection Criteria**:
- Match system pressure and flow requirements to the pump’s ratings.
- Ensure oil cleanliness (recommended NAS Class 8 or higher) to prevent vane wear.
- **Maintenance Guidelines**:
- Replace filters regularly; monitor oil temperature (recommended ≤60°C).
- Inspect shaft seals for leaks; abnormal noise may indicate vane or stator wear.
6. Manufacturers and Alternative Models**
- **Common Brands**:
Bosch Rexroth, Eaton Vickers, Yuken, Kawasaki Heavy Industries, etc., offer similar vane pump lines.
- **Alternate Models**:
If the original model is unavailable, match displacement, pressure, and port size (e.g., Rexroth PV2R1-50).
the 50T LR Hydraulic Vane Pump
I. Basic Concept
The 50T LR hydraulic vane pump is a type of液压泵 (hydraulic pump) that uses the principle of vane rotation for pumping. Among them, "50T" may indicate the model or specification of the pump, "LR" may represent a specific series or configuration, and "hydraulic vane pump" clearly identifies its attributes as a vane pump used in hydraulic systems.
II. Working Principle
The working principle of the hydraulic vane pump is based on the change in the volume of sealed chambers. When the pump is operating, the rotor rotates within the stator, and the vanes are pressed against the inner surface of the stator by centrifugal force and oil pressure, forming sealed chambers between adjacent vanes. As the rotor rotates, the volume of these sealed chambers constantly changes, enabling the functions of suction and discharge of oil. Specifically, when the volume of the sealed chamber increases, a partial vacuum is formed, and oil is drawn in under atmospheric pressure. When the volume decreases, the oil is compressed and discharged, thereby generating pressure energy.
III. Main Features
1. High-Pressure Performance: Hydraulic vane pumps typically have high working pressures, capable of meeting the demands of high-pressure systems.
2. Stable Flow Rate: Through precise design and manufacturing, hydraulic vane pumps can provide a stable flow rate output.
3. Compact Structure: The pump body has a compact structure, with a small volume and light weight, facilitating installation and maintenance.
4. Smooth Operation: Vane pumps produce minimal vibration and noise during operation, enhancing the reliability and service life of the equipment.
IV. Application Fields
The 50T LR hydraulic vane pump is widely used in various situations requiring high-pressure, large-flow hydraulic systems, such as:
1. Heavy Machinery: Including excavators, cranes, etc., which require powerful hydraulic power to drive various operating mechanisms.
2. Construction Equipment: Such as concrete pump trucks, bulldozers, etc., which require stable hydraulic pressure to ensure smooth operation.
3. Industrial Automation: In automated production lines, hydraulic vane pumps provide precise control and reliable drive to ensure smooth production processes.
V. Performance Parameters
The performance parameters of hydraulic vane pumps typically include pressure, displacement, flow rate, rotational speed, power, and efficiency. For the 50T LR hydraulic vane pump, its specific performance parameters may vary depending on the manufacturer and model. Therefore, when selecting and using the pump, it is essential to refer to the product manual and technical parameter table provided by the manufacturer to ensure that the pump's performance meets actual needs.
VI. Maintenance and Servicing
To ensure the long-term stable operation of the 50T LR hydraulic vane pump, regular maintenance and servicing are required. This includes checking the pump's sealing performance, cleaning the oil circuit, replacing hydraulic oil and filters, etc. At the same time, it is important to avoid operating the pump under overload or overheated conditions to extend its service life.
In summary, the 50T LR hydraulic vane pump is a hydraulic pump with high-pressure performance, stable flow rate, compact structure, and smooth operation. It is widely used in heavy machinery, construction equipment, and industrial automation fields, providing powerful hydraulic power for various equipment. When selecting and using the pump, it is important to refer to the product manual and technical parameter table provided by the manufacturer and to perform regular maintenance and servicing.
