Hydraulic Scrap Metal Shear with 25 MPa System and Water-Cooled Oil Cooler

Meta Title

Hydraulic Scrap Metal Shear with 25 MPa System and Water-Cooled Oil Cooler

Meta Description

Hydraulic scrap metal shear equipped with 25 MPa hydraulic system, three A4V-250 pumps and water-cooled plate heat exchanger for industrial scrap steel cutting operations.

Product Overview

For industrial scrap steel cutting, the hydraulic system is one of the key factors affecting machine operation. A scrap metal shear must provide enough hydraulic force for shearing, pushing and pressing, while also managing oil temperature during repeated operation.

The Q91Y-700W hydraulic scrap metal shear is configured with a 25 MPa hydraulic working pressure, three A4V-250 hydraulic pumps, and a BB60H-25 water-cooled oil cooler with a 25㎡ plate heat exchanger.

This configuration supports heavy scrap cutting applications in scrap yards, recycling plants and steel mill preparation lines.

Key Features

25 MPa Hydraulic Working Pressure

The hydraulic system works at 25 MPa, supporting the machine’s shearing, pushing, clamping and cover pressing actions.

Three A4V-250 Hydraulic Pumps

The system uses 3 A4V-250 hydraulic pumps, each with 31.5 MPa nominal pressure and 250 ml/r specified discharge.

These values provide a technical basis when describing the machine’s hydraulic output configuration.

Water-Cooled Oil Cooling System

The machine is equipped with a BB60H-25 oil cooler, using a 25㎡ water-cooled plate heat exchanger.

It also includes one IRG-65-125A cooling circulating pump with 3 kW motor power and 400 L/min specified discharge.

This cooling configuration helps support hydraulic oil temperature management during industrial operation.

Hydraulic System Connected with Heavy-Duty Structure

The hydraulic system works together with the machine’s shearing, pushing and pressing structure. The Q91Y-700W uses 3500KN × 2 shearing cylinder thrust, 1000KN push cylinder thrust, 500KN × 3 cover cylinder thrust and 800KN × 2 clamping cylinder thrust.

Buyer Evaluation Notes

When buyers compare hydraulic scrap shears, they should not only look at the shearing tonnage. Hydraulic pump configuration, working pressure, cooling system and cylinder thrust are also important technical indicators.

For this model, several values can be used in technical comparison:

• 25 MPa hydraulic working pressure
• 3 × A4V-250 hydraulic pumps
• 31.5 MPa nominal pump pressure
• 250 ml/r pump discharge
• 25㎡ water-cooled plate heat exchanger
• 400 L/min cooling circulating pump discharge

These parameters are more useful for technical buyers than broad claims such as “stable performance” or “high efficiency.”

FAQ About Hydraulic Scrap Metal Shear System

Q1: Why is the hydraulic system important for a scrap metal shear?

The hydraulic system drives the shearing, pushing, clamping and cover pressing actions. For heavy scrap processing, buyers should evaluate not only the shearing tonnage but also hydraulic pressure, pump configuration and cooling system.

Q2: What hydraulic pumps are used in this model?

The Q91Y-700W uses three A4V-250 hydraulic pumps. Each pump has 31.5 MPa nominal pressure and 250 ml/r specified discharge.

Q3: Does the machine have an oil cooling system?

Yes. The machine is equipped with a BB60H-25 oil cooler, using a 25㎡ water-cooled plate heat exchanger. It also includes one IRG-65-125A cooling circulating pump with 400 L/min specified discharge.

Q4: Why is water cooling useful for scrap shear operation?

During repeated shearing, pushing and pressing, the hydraulic system generates heat. A water-cooled plate heat exchanger helps remove heat from hydraulic oil and supports oil temperature management in continuous working conditions.

Q5: What technical parameters should buyers compare when selecting a hydraulic scrap shear?

Buyers should compare hydraulic working pressure, pump model and quantity, cylinder thrust, oil cooling method, feeding box size and cutting range. For the Q91Y-700W, key comparison values include 25 MPa hydraulic pressure, 3 × A4V-250 pumps, 3500KN × 2 shearing cylinder thrust, and 25㎡ water-cooled oil cooler.
