III. Application Scenarios

1. Straightening Scenario for Heavy Construction Machinery Components: Suitable for straightening and repairing deformed connecting rods, frame crossbeams, and other components of excavators and loaders. In heavy machinery repair shops, fix the deformed component on the 650mm-wide worktable, start the fast-stroke pump to quickly position the ram to the deformed point, then switch to the slow-stroke pump to output 30 tons of stable pressure. The pressure gauge monitors the pressure in real time to avoid component damage due to overpressure, while ensuring the mechanical properties of the straightened component meet standards, reducing the high cost of replacing new components.
2. Thick Steel Plate Shaping Scenario: Used for bending, flanging, and shaping of steel plates and iron plates (30-50mm thick). In large hardware processing plants, the 30-ton pressure is used to bend thick steel plates into large equipment bases, workshop steel structure brackets, etc. The dual-pump design enables quick ram alignment, and then slow and precise pressure application ensures the accuracy of the bending angle. The 120-1070mm working range adapts to workpieces of different heights, eliminating the need for frequent equipment parameter adjustments and improving batch processing efficiency.
3. Press-Fitting Scenario for Heavy Auto Components: For press-fitting of large-sized bearings of truck and bus gearboxes, drive axle bushings, and other components. In auto repair centers, use the fast-stroke pump to quickly push the bearing to the installation position, then switch to the slow-stroke pump to output stable pressure for press-fitting. The pressure gauge displays the pressure value in real time to avoid damage to the gearbox housing due to overpressure, while ensuring the fitting accuracy between the bearing and the bushing, reducing the risk of subsequent driving failures.
4. Disassembly Scenario for Large Agricultural Machinery Components: Used for disassembling aging heavy components of tractors and harvesters (such as engine blocks and cylinder liners, large gear sets). In agricultural machinery repair stations, use 30-ton pressure with special tooling, and adjust the disassembly speed through dual-pump control: the fast-stroke pump quickly approaches the component, and the slow-stroke pump applies stable pressure to separate the aging fitted components. This avoids component damage caused by brute-force disassembly, improving the disassembly success rate and efficiency.

IV. Frequently Asked Questions (FAQs)

(I) What to Do If There Is Jamming When Switching Between Dual Pumps and It Is Impossible to Smoothly Switch from Fast Stroke to Slow Stroke?

1. First, check if the dual-pump switching valve is blocked by impurities: Turn off the equipment power and hydraulic oil circuit, disassemble the switching valve, rinse the valve core and valve body with hydraulic oil to remove impurities, then reinstall. If the sealing ring of the switching valve is aging, replace it with a sealing ring of the same model to avoid switching jamming caused by poor sealing.
2. Check the hydraulic oil level and oil quality: If the hydraulic oil level is below the minimum scale line, add 46# anti-wear hydraulic oil to the normal level; if the hydraulic oil is turbid and contains impurities, completely replace it with new oil and clean the hydraulic oil tank. Poor oil quality will increase the switching resistance of the dual pumps, leading to jamming.
3. If the above operations are ineffective, check if the connecting pipelines of the dual pumps are loose: Tighten the pipeline joints one by one with a wrench. If there is leakage at the pipeline interface, replace the sealing gasket and re-tighten to ensure stable hydraulic oil transmission and avoid switching failures caused by pressure loss.

(II) Why Does the Workpiece Still Have Substandard Deformation (Such as Deviation in Bending Angle) After Processing Even Though the Pressure Gauge Shows Normal Pressure?

1. Check if the worktable is level: Use a level to test the worktable surface. If the worktable is tilted, pressure will be unevenly distributed. Insert adjustment gaskets under the worktable base to keep the worktable level, ensuring uniform pressure application on the workpiece.
2. Confirm if the workpiece is fixed firmly: If the workpiece is not fixed with special tooling or clamps, it is prone to displacement during processing. Select suitable tooling such as V-blocks and pressure plates according to the workpiece shape, and fix the workpiece tightly on the worktable to avoid workpiece displacement during processing.
3. Check the pressure stability of the dual-pump slow stroke: Start the slow-stroke pump and observe if the pressure gauge pointer fluctuates. If the pointer jumps violently, the internal part of the slow pump may be worn. Contact the manufacturer for maintenance or replace the slow pump to ensure stable pressure output and guarantee processing accuracy.

(III) How to Handle Abnormal Heating of the Hydraulic System During Equipment Operation, with the Outer Wall of the Oil Tank Feeling Significantly Hot to the Touch?

1. Check if the hydraulic oil is excessive or insufficient: If the oil level exceeds the maximum scale line, drain the excess hydraulic oil to the normal level; if the oil level is too low, add hydraulic oil. Abnormal oil level will cause poor circulation of hydraulic oil, leading to overheating.
2. Check if the heat dissipation components of the hydraulic system are blocked: Clean the dust and debris on the external heat dissipation holes and cooling fan of the oil tank. If the cooling fan fails to rotate, check the fan motor and circuit, and replace the faulty components to ensure the normal operation of the heat dissipation system.
3. Confirm if the equipment has been operating under overload for a long time: The 30-ton rated capacity is the upper limit for continuous operation. If the equipment operates at full load for more than 3 hours continuously, pause it for 1 hour to cool down the hydraulic system, avoiding the increase of hydraulic oil temperature due to overload, which affects equipment service life and processing accuracy.

(IV) What to Do If the Ram Does Not Move and the Hydraulic System Has No Pressure Output When the Equipment Is Started for the First Time After Transportation or Installation?

1. Check if the hydraulic system has been thoroughly vented: New equipment or installed hydraulic pipelines may have residual air. After starting the equipment, repeatedly operate the dual-pump switching valve, and at the same time loosen the hydraulic cylinder vent valve to discharge the air in the pipeline until no air bubbles emerge from the vent valve, then close the vent valve and test the ram movement.
2. Check if the motor rotation direction is correct: Disconnect the motor power supply, swap the two power lines at the motor terminal to adjust the motor rotation direction. Reverse motor rotation will cause the hydraulic pump to fail to suck oil normally, resulting in no pressure output.
3. Check if the hydraulic pump oil inlet filter is blocked: Disassemble the oil inlet filter. If the filter is blocked by packaging debris or dust, blow it clean with compressed air or replace it with a new filter to ensure the hydraulic pump can suck oil normally and restore pressure output.
