This is a system that detects oil leaks caused by a decrease in sealing performance due to wear of rod packing in hydraulic cylinders and similar equipment, and notifies the timing for packing replacement wirelessly via radio communication. It can monitor up to 100 units, eliminating the need for maintenance checks on each individual unit. The communication range is up to 3 km in suburban areas. It operates on six AA alkaline batteries, with a maximum lifespan of approximately 8 years.

By modifying your current cylinder to be IoT-compatible, it is possible to detect oil leaks. It can be retrofitted to your existing cylinder without any modifications. If it is a JIS-type cylinder, it can be installed without any alterations. It is possible to detect oil leaking from the piston rod sliding part before it escapes to the outside. (Patent obtained) By connecting a JIS-type cylinder equipped with this product to a leak detection device (sold separately), it accurately informs you of the maintenance timing for the cylinder due to wear of the packing and other factors.

New heat-resistant signal leak floor product launched! Unlike standard products, it monitors oil leaks with a sensor that excels in high-temperature resistance. It operates stably even in high-temperature environments that are difficult for standard products (normally 50°C → this product 125°C).

It detects signs of oil leakage before it occurs. To prevent false detection due to condensation and other factors, it is equipped with an internal primary oil collection tank of approximately 5cc. Various installation methods are available, including floor placement, wall mounting, horizontal piping, and vertical piping.

Many of the orders for aftermarket parts are for rod bushes and piston assemblies. (Most are due to uneven loading caused by misalignment.) Reduction in the frequency of packing maintenance Reduction in disposal frequency due to long life Decrease in the number of oil leaks Structure designed to incorporate wear rings and piston packing that have high lubrication properties and reduce eccentricity at the bearing section Select packing with excellent sliding properties according to the usage environment and operating oil conditions.

A hydraulic cylinder has been equipped with a hydraulic oil circulation function, reducing the deterioration of seals and lowering maintenance costs.

By combining tap water and cutting fluid with super alkaline ion water (SAIW), the lifespan of cutting tools is improved. Super alkaline ion water (SAIW) has the effect of suppressing the oxidation of coolant fluids as well as anaerobic bacteria and foul odors. It has a high cleaning power similar to organic solvents, and replacing it with super alkaline ion water (SAIW) leads to an improvement in the working environment and a reduction in the storage amount of hazardous materials.

1. High Pressure Specification Achieves the highest level of high pressure in its class. Rated pressure is 35MPa, and it supports a maximum peak pressure of 40MPa. By reducing the diameter of the cylinder, it enables compact design, shorter processing cycles, and a reduction in the amount of operating oil used. 2. Energy Saving By reducing friction losses at each sliding part and internal leakage, it demonstrates energy-saving performance that surpasses competitor products. It contributes to reducing the running costs of the machine and suppressing oil temperature rise. 3. Low Noise Achieves the highest level of low noise through reducing pressure pulsation and improving the rigidity of the internal structure.

Controls the rotation speed and direction of the hydraulic pump with an AC servo motor. Powerful performance with a maximum pressure of 30MPa. Positioning in the micrometer range is also possible with a servo controller. Compact and integrated design achieves space-saving.

Control the rotation speed and direction of the hydraulic pump with an AC servo motor. It generates flow and pressure according to the machine cycle and can be stopped during idle time. Operating only when necessary leads to significant energy savings. Additionally, by adopting a high-speed digital processing servo controller, high-precision control of position, speed, and pressure is achieved.

The NSPi series, well-received for its high energy-saving performance, has newly added monitoring functions and functional safety.

DIN EN 175301-803-A, ISO 4400 compatible Digital amplifier for proportional valves in our smallest size IP65 rated Selectable input methods of voltage 0-10V, 1-5V, and current 4-20mA Digital communication enables acquisition of pressure/flow/current commands and status (solenoid current, abnormalities) Automatically controls solenoid current to maintain constant pressure using pressure sensor information Easily connect to a PC with a commercially available USB-C cable for parameter setting and writing without a power supply via USB power.

All parameters can be set numerically. For example, you can simply set numerical values for the dither frequency and the maximum output current. There is no need to configure settings while checking the waveform. When driving one proportional valve, you can switch between 32 patterns of command currents. Convenient features such as output current monitoring for the solenoid coil and alarm displays for coil shorts have been added. By using dedicated tool software, all parameters can be backed up and set in bulk, making it easy to configure the control amplifier for the second and subsequent units. Current feedback control maintains the commanded coil current even if the coil temperature changes. It is possible to control two valves simultaneously with pressure feedback control, suppressing pressure changes due to variations in operating oil temperature and override characteristics. Additionally, the ON/OFF of feedback control can be switched based on input signals. It complies with international safety standards with CE marking. The conventional ERD-PA3D6-D2-10 and analog amplifiers can be easily replaced with this product. Monitoring the commands and status of the valves can be achieved through digital communication using a single LAN cable.

NACHI HYDRO LOGIC "Composite Valve Series." This series completely redesigns the structure of conventional hydraulic control valves, making it a truly multifunctional composite valve that can control multiple functions with a single valve. It demonstrates excellent power in compacting and reducing costs of hydraulic devices, providing immeasurable benefits to all hydraulic systems, starting with small to medium capacity systems. It is indeed an advanced valve that meets the needs of the times—a multifunctional composite valve.

Since there is no drain flow, it can be applied to energy-saving operations. High response and high precision switch output can be obtained. The lifespan has been extended, and reliability has improved. The set pressure and hysteresis can be freely adjusted within the range using an electric trimmer. The switch output and internal circuit are electrically isolated by a photcoupler, so there is no concern about malfunction due to noise. The pressure detection part has been miniaturized, eliminating constraints during valve stacking.
