Hydraulic Pump Mounting Frame

Product Specifications

Technical details and manufacturing context for Hydraulic Pump Mounting Frame

Definition

The Hydraulic Pump Mounting Frame is a specialized structural component used in machinery and equipment manufacturing. It provides a rigid, vibration-resistant platform for mounting hydraulic pumps, ensuring proper alignment and reducing stress on pump components. The frame transfers the weight and operational forces of the pump to the main structure while isolating vibrations, maintaining precise pump positioning for correct fluid connections and drive system alignment. It is designed to facilitate maintenance access and maintain structural integrity under operational loads.

Typical materials include carbon steel and stainless steel, with frame material grades such as Q235B for standard applications and 45# for high-strength requirements, per GB/T 700. Surface treatment options include phosphating plus powder coating for indoor use, with hot-dip galvanizing recommended for outdoor environments. The frame is available in various configurations, with footprint dimensions ranging from 400×300 mm to 800×600 mm, and weight typically between 15 and 60 kg, depending on pump size and configuration.

Key parameters include a rated pressure range of 16–31.5 MPa, with special seals and thicker flanges required above 31.5 MPa. Mounting hole diameters range from Ø13 to Ø26 mm to match standard bolts M12–M24 (ISO 273). Center distance tolerance is ±0.05 mm (ISO 2768-m), and flatness is 0.10 mm (ISO 1101) to prevent distortion and vibration. The operating temperature range is -20 to +80 °C; outside this range, high-temperature or low-temperature steel should be used. Vibration resistance is tested at 5–500 Hz, 2.5 g (IEC 60068-2-6), with damping mounts required above 2.5 g.

All values are reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. Standards listed are procurement references and do not imply certification or compliance.

Working Principle

The frame operates by providing a rigid base that supports the hydraulic pump and transfers its weight and operational forces to the main machinery structure. It isolates vibrations through its structural design and material properties, reducing stress on pump components. The frame maintains precise pump positioning, ensuring proper alignment with fluid connections and drive systems. This alignment is critical for efficient operation and to prevent premature wear. The frame's flatness and center distance tolerance are controlled to avoid distortion and misalignment. Maintenance access is facilitated by the frame's design, allowing for inspection and service without compromising structural integrity.

Frequently Asked Questions

What materials are available for the mounting frame?

The frame is typically made from carbon steel or stainless steel. Specific grades include Q235B for standard applications and 45# for high-strength requirements, as per GB/T 700. The choice depends on the application's strength and corrosion resistance needs.

What is the rated pressure range for this frame?

The rated pressure range is 16–31.5 MPa. For pressures above 31.5 MPa, special seals and thicker flanges are required. Always verify the actual pressure rating for your specific model with the manufacturer.

How is the frame surface treated?

Standard surface treatment is phosphating plus powder coating, suitable for indoor use. For outdoor applications, hot-dip galvanizing is recommended to enhance corrosion resistance. Confirm the appropriate treatment for your environment.

What are the mounting hole diameters?

Mounting hole diameters range from Ø13 to Ø26 mm, designed to match standard bolts M12–M24 (ISO 273). Ensure the bolt size and hole diameter are compatible for secure mounting.
