The High-Pressure Hydraulic Pump is a hydraulic power device centered on "ultra-high pressure output + precise flow control". Designed specifically for high-pressure hydraulic tool driving scenarios, it addresses the pain points of traditional hydraulic pumps such as "insufficient pressure, unstable flow, and easy reservoir corrosion". Through the design of a steel reservoir and high-precision pump core, it achieves the core needs of "high-pressure efficiency, long-term durability, and multi-scenario adaptation", suitable for engineering maintenance, industrial assembly, heavy equipment maintenance and other scenarios. Its core advantages are as follows:
- 70MPa Ultra-High Hydraulic Pressure, Strong Power:Breaking the pressure limit of ordinary hydraulic pumps, the maximum hydraulic pressure reaches 70MPa, which can easily drive high-pressure hydraulic tools such as hydraulic wrenches and hydraulic breakers — when driving a hydraulic wrench, it can quickly tighten/remove heavy bolts (such as flange bolts of engineering equipment). Compared with ordinary 20MPa hydraulic pumps, the bolt disassembly and assembly efficiency is increased by 2.5 times; the working pressure can be flexibly adjusted between 0.4-1.17MPa, adapting to the pressure needs of different high-pressure tools, avoiding tool damage or inefficient operation caused by mismatched pressure.
- Dual-Flow Adaptation, Efficient for No-Load & Loaded Scenarios:The output flow reaches 490ml/min under no-load, which can quickly fill the hydraulic system with oil, shortening the tool start-up preparation time (e.g., it only takes 30 seconds to fill the hydraulic jack to the working state); when loaded, it automatically switches to a stable flow of 130ml/min, ensuring the balance between pressure and flow during high-pressure operations, avoiding tool jamming caused by flow fluctuations (e.g., no impact attenuation when the hydraulic breaker is continuously breaking), balancing "start-up speed" and "operation stability".
- Steel Reservoir + High-Precision Pump Core, Durable & Corrosion-Resistant:The reservoir is made of high-quality steel with a thickness of 2mm, impact-resistant and high-pressure-resistant, with no deformation or leakage under 70MPa pressure; the inner wall of the reservoir is treated with rust prevention, and the 690ml capacity can meet the oil supply demand for 4 hours of continuous operation, avoiding frequent oil refilling; equipped with a 7mm high-precision pump core, the surface finish of the pump core reaches Ra0.8μm, reducing hydraulic oil leakage, and the flow control precision error is ≤3%. Compared with ordinary cast iron pump cores, the service life is extended by more than 3 times.
- NPT Standard Interface + Compact Size, Strong Adaptability:The input and output ports adopt 1/4-inch NPT standard threads, adapting to quick connectors of most high-pressure hydraulic tools worldwide, and can be connected and used without additional modification, with compatibility over 98%; the equipment size is only 368175190mm, equivalent to the size of a small microwave oven, and the net weight (referring to products of the same specification) is about 8-10kg, which can be easily carried by one person; the packing size of 380180200mm is convenient for storage and transportation, adapting to the needs of "narrow space operation and flexible scheduling of multiple workstations".
- High-Pressure Bolt Disassembly & Assembly at Engineering Sites:When maintaining large equipment (such as tower cranes and excavators) at construction and mining engineering sites, use this hydraulic pump to drive high-pressure hydraulic wrenches. The 70MPa high pressure can quickly tighten/remove heavy bolts above M30 (such as flange bolts of engineering equipment), and the 0.4-1.17MPa pressure adjustment adapts to the torque needs of bolts of different specifications; the no-load large flow shortens the wrench start-up time, and the loaded stable flow ensures the precision of bolt disassembly and assembly, adapting to the engineering needs of "efficient maintenance and precise operation" and solving the problem of laborious manual disassembly and assembly of heavy bolts.
- Precision Assembly in Industrial Workshops:When auto manufacturing and heavy machinery assembly workshops use hydraulic presses for precision component assembly (such as engine block and crankshaft assembly), the 70MPa high pressure of the hydraulic pump can provide stable pressure, and the 130ml/min loaded flow ensures uniform pressing speed (pressing speed can be controlled at 0.5cm/s), avoiding component assembly deviation caused by pressure fluctuations; the steel reservoir is resistant to oil pollution and corrosion, adapting to long-term use in oily workshop environments and improving the qualification rate of precision assembly.
- Outdoor Emergency High-Pressure Maintenance:When power emergency repair and road rescue sites need to use hydraulic breakers to clear obstacles (such as concrete blocks and metal debris), this hydraulic pump can be carried with the vehicle (packing size compatible with SUV trunks), and the 70MPa high pressure drives the breaker to work efficiently, with the 490ml/min no-load flow quickly starting the equipment; no external power supply is needed, and it can operate with manual/pneumatic drive (adapting to high-pressure scenario needs), adapting to the scenario of "no electricity outdoors and emergency repair" and solving the problem of lack of high-pressure power on site.
- Hydraulic System Maintenance of Heavy Equipment:When maintaining heavy cranes and container handling equipment in ports and logistics parks, the 70MPa high pressure of the hydraulic pump can be used to test the tightness of the hydraulic system (such as detecting whether the hydraulic pipeline leaks), and the 0.4-1.17MPa working pressure adjustment adapts to the needs of different test stages; the steel reservoir is resistant to seawater corrosion (port scenarios), and the 690ml capacity meets the oil supply for a single system test, adapting to the port maintenance scenario of "high salt spray and high intensity" and ensuring the stable operation of the equipment hydraulic system.
A1:It can be judged by two steps: ① Check the hydraulic wrench manual to confirm whether the required working pressure is within the range of 0.4-1.17MPa, and whether the maximum pressure is ≤70MPa (to avoid tool damage caused by overpressure); ② Check if the wrench interface is 1/4-inch NPT thread. If the interface specification is consistent, it can be directly connected without modification; if the interface is different, an NPT adapter (high-pressure adapter with pressure resistance ≥70MPa is required) can be used to ensure no pressure leakage after connection.
A2:The maintenance process is simple: ① Turn off the pump body, release the internal pressure, remove the reservoir cover, and check if the hydraulic oil is deteriorated (if the oil is turbid and has impurities, replace it with No. 46 high-pressure anti-wear hydraulic oil), and add oil to the reservoir scale line (the 690ml capacity is about 2/3 of the reservoir height); ② Clean the filter screen of the input and output ports with a high-pressure air gun to remove dust and impurities and prevent oil circuit blockage; ③ Disassemble the pump core, wipe it with alcohol and apply hydraulic-specific grease, reinstall it and run the pump body under no-load for 5 minutes, and the flow can be restored to normal without professional maintenance.
A3:No safety risk. The equipment has built-in triple safety protection: ① Pressure relief valve: When the pressure exceeds 70MPa, it automatically relieves pressure to protect the pump body and connected tools; ② Explosion-proof reservoir design: The steel reservoir has passed the burst test, with a limit pressure resistance of 100MPa, far exceeding the 70MPa working
