Detailed Content of High-Pressure HVP30 Vane Pump
I. Product Overview
The High-Pressure HVP30 Vane Pump is a specially designed high-pressure variable vane pump. It adopts a pressure-limiting variable mechanism, capable of providing large flow at low pressure and reducing flow at high pressure, thereby reasonably utilizing power, effectively reducing motor consumption power, and conserving energy.
II. Product Features
1. Efficient and Stable: When the HVP30 operates with "shaft gap compensation" under high pressure and continuous rotation, it exhibits stable performance and high efficiency. Its "eccentric plunger" responds quickly, with agile startup, stop, load rotation, and action.
2. Easy Pressure Adjustment: The HVP30 offers a wide range of pressure adjustment with high stability and fast response speed.
3. Convenient Assembly: The pump is easy to assemble and can be directly combined with a motor to form a motor-pump combination, facilitating installation and use.
4. Adjustable Displacement: The HVP30 features displacement adjustment functionality, allowing adjustment of the pump's displacement according to actual needs to meet different working pressures and flow requirements.
III. Technical Parameters
1. Model: HVP30
2. Displacement: The specific displacement may vary among different manufacturers and products, but the displacement of the HVP30 series typically falls within a certain range.
3. Pressure Range: The pressure adjustment range is wide, usually adjustable between 30~140bar according to demand.
4. Rotation Speed: The pump's rotation speed is typically high, such as 1800RPM, to provide sufficient flow and pressure.
5. Operating Temperature: The working temperature of the hydraulic oil connection should be maintained within a certain range, such as 15 to 60 degrees Celsius, to ensure normal pump operation and extend service life.
IV. Usage Precautions
1. Installation Requirements: When assembling the motor shaft center and pump shaft center using a coupling, the parallelism error should be within 0.05mm, and the angular error should be within 1 degree.
2. Drain Oil Pipe Connection: The external drain port of the variable pump must directly connect back to the oil tank without returning oil through other oil pipes, and the drain oil pipe must be below the oil level.
3. Suction Port Height: The pump suction port should not be higher than 1 meter above the oil level to ensure sufficient suction pressure and avoid cavitation.
4. Hydraulic Oil Selection: Select appropriate hydraulic oil based on the working pressure and temperature range, such as using hydraulic oil with a viscosity of 30~50cSt (ISO VG32) at 40°C for pressures below 70bar, and hydraulic oil with a viscosity of 50~70cSt (ISO VG46) at 40°C for pressures above 70bar.
5. Displacement and Pressure Adjustment: When adjusting the displacement, first loosen the adjustment nut and then rotate the adjustment screw; when adjusting the pressure, rotate the pressure adjustment screw to achieve the desired pressure.
V. Application Fields
The High-Pressure HVP30 Vane Pump is widely used in various mechanical equipment, such as injection molding machines, die-casting machines, hydraulic presses, etc., providing them with stable high-pressure hydraulic power.
In summary, the High-Pressure HVP30 Vane Pump is characterized by efficient stability, easy pressure adjustment, convenient assembly, and other features. It is one of the commonly used high-pressure hydraulic power sources in mechanical equipment. When using it, attention should be paid to installation requirements, drain oil pipe connection, suction port height, hydraulic oil selection, and displacement and pressure adjustment to ensure normal pump operation and extend service life.
### **1. Model & Brand Association**
- **HVP30**: Likely a model code for a high-pressure vane pump from a specific brand. For example, **YEESEN Hydraulic Vane Pump** (referenced in "Webpage 1") includes the model **HVP-30-140**, which operates at up to **400 bar (~40 MPa)**, confirming its high-pressure capability.
- The "30" in the model may denote displacement (e.g., 30 cc/rev) or a series identifier. "HVP" likely stands for "High-Pressure Vane Pump."

- Some models include built-in pressure compensation valves for automatic flow adjustment (e.g., "rotational clearance compensation" in "Webpage 1").
2. **Low Pulsation & Noise**:
- Inherent smooth flow output makes it suitable for precision systems (e.g., machine tool hydraulics).
3. **Durability**:
- Uses wear-resistant materials and sealing technology (e.g., "U.S.-made seals" in "Webpage 3") to extend service life.

### **5. Maintenance & Failure Prevention**
- **Key Maintenance Tips**:
- Maintain oil cleanliness (NAS Class 8 or higher) to prevent vane wear or jamming.
- Inspect shaft seals for leaks; abnormal noise may indicate internal wear (e.g., stator ring or vane damage).
- Avoid prolonged overpressure operation (>90% rated pressure) to prevent overheating.
- **Failure Modes**:
- **Cavitation**: Caused by clogged inlet filters or insufficient suction pressure (check filters and oil level).
- **Pressure Fluctuation**: May result from seal failure or compensation valve malfunction.
