Core features of A37 series radial piston pump for Oil research injection molding machine

YUKEN A37 series radial piston pumps are specially designed for high-pressure hydraulic systems of injection molding machines. The core characteristics focus on the three core advantages of high efficiency, stability and strong adaptability. The details are as follows:

  1. High efficiency and energy saving, lower operating costs
    Using optimized hydrodynamic structure and precision manufacturing technology, the total efficiency is as high as more than 90%, of which the volumetric efficiency can exceed 98% at a pressure of 16MPa and a speed of 1800r/min.It has excellent shut-off characteristics and can automatically adjust the output according to the system load. Compared with ordinary quantitative pumps, it can save 15-30% of the input power. At the same time, the power loss is small and the oil temperature rises slowly, which can reduce the fuel tank capacity and further reduce equipment supporting and operating costs.
  2. Low-noise design, smoother operation
    Through structural optimization and precision assembly control, the operating noise is significantly lower than that of similar products in the industry. Under conventional operating conditions, the noise level is lower than 57.3dB (A), and some models can be as low as 55dB (A) at 1 meter under 1500rpm and 7MPa operating conditions, which can effectively improve the operating environment of the injection molding workshop.
  3. Stable high pressure, suitable for the core needs of injection molding
    The maximum working pressure can reach 21-28MPa, which can stably meet the high-pressure requirements of key processes such as mold closing and glue injection of injection molding machines, and the pressure output fluctuation is small, which can ensure the accuracy and consistency of product molding.At the same time, it supports operation in a wide speed range of 600-1800rpm, and the flow adjustment range covers 10-37cc/rev, which is suitable for the power requirements of different tonnage injection molding machines.
  4. Flexible variable control, suitable for multiple processes
    It provides a variety of precise control methods, including pressure compensation control, electro-hydraulic proportional load sensitive control, remote pressure control, etc., which can realize stepless adjustment of pressure and flow.It can quickly respond to load changes in different cycles such as glue injection, pressure holding, and cooling of the injection molding machine. For example, the pressure can be accurately compensated in the pressure holding stage, and the flow rate can be automatically reduced in the cooling stage and enter the energy-saving mode, which is suitable for multiple process scenarios such as precision injection molding and high-speed injection molding.
  5. High reliability and low maintenance costs
    Modular and reinforced structure design: the 9 plungers are made of high-quality alloy steel, and the distribution plate is made of bronze/steel composite materials, which have excellent self-lubricating and wear resistance; with heavy-duty roller bearings and multiple sealing structures, high fatigue strength can effectively prevent oil leakage and extend service life.At the same time, it has a compact structure and light weight (about 30-32.3kg). The flange installation method is adapted to the layout of the hydraulic station of the injection molding machine, and the modular design makes maintenance more convenient.
