在机床夹具、硫化成型、保压测试等众多工业场景中，液压系统往往面临一个核心工况：“长时间保压且要求系统低发热”。如果仅依靠液压泵持续运转来维持压力，不仅会造成大的能源浪费，还会导致液压油温急剧升高，进而加速元件老化。
- 经典的“蓄能器+压力开关”零功耗保压回路
我们在集成阀块上直接配置了隔膜式蓄能器和电接点压力表。
工作逻辑：当系统达到设定的工作压力时，压力继电器发出电信号，通过侧面的电控箱自动切断电机电源，液压泵停止工作。此时，由蓄能器释放压力油来补偿系统的微小泄漏，维持载荷压力。当压力下降到设定下限时，电机再次启动补压。
客户收益：实现了真正意义上的“零功耗待机保压”，彻底解决了油温过高的问题，大幅延长了液压泵和电机的使用寿命。 - 拒绝软管老化：不锈钢硬管与卡套连接
细微之处见真章。从图中可以看出，压力表、压力继电器与主阀块之间的测压管路，我们并没有采用易老化的橡胶软管，而是采用了不锈钢硬管配合精密卡套接头进行连接。这种工业级的硬管布线，不仅提升了设备的整体质感，更从根本上消除了软管在长期高压脉冲下可能发生的爆管或渗漏风险，确保了系统压力的绝对稳定。 - 到手即用的“交钥匙”工程
对于非标设备制造商而言，最头疼的往往是液压与电气的匹配布线。我们将液压控制（阀块）、动力源（电机泵组）、传感器（压力继电器）与执行大脑（侧边悬挂的电控箱）整合在同一个底座上。所有传感器的信号线均已接入控制柜，客户现场只需接入主电源及油缸管路，即可实现全自动的保压控制。

Efficient Pressure-Maintaining Hydraulic Power Unit
In numerous industrial scenarios such as machine tool fixtures, vulcanization molding, and pressure-holding tests, hydraulic systems often face a core operational requirement: “long-term pressure maintenance with low system heat generation.” Relying solely on the continuous operation of the hydraulic pump to maintain pressure not only causes significant energy waste but also leads to a sharp increase in hydraulic oil temperature, thereby accelerating component aging.
The Classic “Accumulator + Pressure Switch” Zero-Power Pressure-Maintaining Circuit
We directly configure a diaphragm accumulator and an electrical contact pressure gauge on the integrated manifold block.
- Working Logic: When the system reaches the preset operating pressure, the pressure relay sends an electrical signal to automatically cut off the motor’s power supply via the side-mounted electrical control box, stopping the hydraulic pump. At this point, the accumulator releases pressurized oil to compensate for minor system leaks, maintaining the load pressure. When the pressure drops to the preset lower limit, the motor restarts to replenish the pressure.
- Customer Benefits: This achieves true “zero-power standby pressure maintenance,” completely resolving the issue of excessive oil temperature and significantly extending the service life of both the hydraulic pump and the motor.
Rejecting Hose Aging: Stainless Steel Hard Piping with Compression Fittings
True quality is revealed in the details. As seen in the images, for the pressure measurement lines connecting the pressure gauge, pressure relay, and main manifold block, we do not use easily aged rubber hoses. Instead, we use stainless steel hard tubing paired with precision compression fittings. This industrial-grade hard piping layout not only enhances the overall aesthetic quality of the equipment but fundamentally eliminates the risk of hose bursts or leaks under long-term high-pressure pulses, ensuring absolute stability of the system pressure.
Ready-to-Use “Turnkey” Engineering
For manufacturers of non-standard equipment, the most troublesome aspect is often the matching and wiring of hydraulics and electrics. We integrate the hydraulic control (manifold block), power source (motor-pump group), sensors (pressure relay), and execution “brain” (side-mounted electrical control cabinet) onto a single base. The signal lines for all sensors are pre-wired into the control cabinet. At the customer’s site, one only needs to connect the main power supply and the cylinder pipelines to achieve fully automatic pressure-maintaining control.
Our Distinctive Features in Underlying Design and Manufacturing as a System Integrator
- AUTOMATION STUDIO LIVE MANIFOLD: Breaking Through Manifold Design Bottlenecks
A pressure-maintaining manifold block with an accumulator interface often contains complex valve cavities, logic fluid passages, and pressure measurement channels internally.- 3D Error-Proofing and Hydraulic Simulation Verification: We fully rely on the AUTOMATION STUDIO LIVE MANIFOLD software for digital twin design. Prior to machining, the software conducts logic and performance verification for each SUN and HYDRAFORCE cartridge valve cavity in a 3D space, precisely controlling the minimum safe wall thickness between passages.
- Rapid Response: Leveraging the software’s automated drawing generation capabilities, we can shorten the design cycle for such complex, customized manifold blocks from days to hours, greatly accelerating the progression of our customers’ projects.
- Massive Inventory of Original Imported Components: Rejecting Delays
The success of a pressure-maintaining system depends on the internal leakage rate (zero-leakage level) of the cartridge valves and the sensitivity of the pressure relay. As a senior system integrator for brands like SUN, HYDRAFORCE, and ARGO HYTOS, we maintain a massive year-round inventory of original zero-leakage cartridge valves and control components. The core control valve cartridges shown in the images are drawn directly from our ready-to-ship stock. This not only guarantees quality but also spares customers from lengthy wait times for imported procurement. - Owned Factory: Quality is Not Outsourced
We own our production land, factory buildings, and high-end CNC machining centers. The design code exported from LIVE MANIFOLD interfaces directly with our machine tools. From the drilling, milling, and precision reaming of the manifold block, to the welding of the oil tank, the precise bending of hard pipes, and the final pressure-holding tests, the entire process is completed within the closed loop of our physical factory. This independently controllable manufacturing model serves as our strongest endorsement for promising high-quality delivery to our customers.
