YUKEN AR22-FR01B-22 Mechanical Piston Pump Long Life ‌High Efficiency

Product Specification

Product Description:

1. Core Advantages and Features ‌

‌High efficiency and energy saving ‌

Volumetric efficiency>98%, total efficiency>90% (pressure 16MPa, speed 1800r/min), energy consumption is significantly lower than ordinary hydraulic pumps.
Low power loss, low oil temperature rise, can reduce the demand for oil tank capacity.

‌Ultra-low noise design ‌

The A16 pump has an operating noise of <57.3dB(A), and uses optimized blade geometry (such as arc blades) to suppress pressure pulsation.

‌High-pressure stable output ‌

The working pressure can reach more than 35MPa, and the precision plunger and cylinder hole cooperate to ensure high-pressure sealing.
The output pressure fluctuates little, suitable for high-precision industrial scenarios (such as injection molding machines, die-casting equipment).

‌Long life and reliability ‌

The cylinder body and key friction pairs are treated with wear-resistant materials, with a design life of more than 10,000 hours.
Low failure rate, enjoys a high reputation in the fields of plastic machinery and metallurgical equipment.

‌Intelligent flow regulation‌

Variable pump series (such as A37-F-R-01-H-K-32) supports stepless adjustment of the swash plate angle, with a control accuracy of ±1%.

‌II. Precautions for use‌

‌(1) Installation and commissioning‌
‌Shaft alignment requirements‌: The deviation between the motor drive shaft and the pump shaft is ≤0.05mm to avoid radial load damage to the bearing.
‌Suction pipe specifications‌: The inner diameter of the suction pipe ≥ the pump port size, the length ≤2m, the elbows ≤3, to prevent air suction.
‌First start‌: Run at no load for 10~15 minutes and check for abnormal vibration/noise.

‌(2) Operation parameter control‌
‌Pressure limit‌: Working pressure ≤80% of the rated pressure (for example: use ≤28MPa when rated at 35MPa).
‌Oil temperature management‌: Maintain 30~60℃ (maximum ≤80℃), high temperature requires a cooler, low temperature requires preheating the oil tank.
‌Oil cleanliness‌: NAS level 7~8 (or ISO 18/15/12) is required, and the filter element should be replaced every 1000~2000 hours.

‌(3) Regular maintenance‌ ‌Replacement of key components‌: The bearing life is about 10,000 hours. If it exceeds the period, it needs to be replaced with original specification accessories. ‌Oil and filter element‌: Replace the hydraulic oil and clean the oil tank every 2000 hours. ‌Seal inspection‌: Check the pump body/pipeline leakage every 500 hours. ‌

(4) Fault prevention‌ ‌Prohibitions‌: Oil contaminant particle size >10μm will accelerate the wear of the friction pair by 212; overpressure and overspeed operation are strictly prohibited. ‌Shutdown maintenance‌: Long-term shutdown requires draining the oil in the pump to prevent corrosion. ‌

III. Typical application scenarios‌ ‌

High-pressure industrial equipment‌: injection molding machine, die-casting machine, forging machine. ‌

Precision control system‌: hydraulic transmission of engineering machinery, aviation hydraulic power unit. ‌

Energy-saving system transformation: Closed hydraulic circuits that need to reduce energy consumption.

Note: The specific maintenance cycle may vary depending on the working conditions, it is recommended to refer to the equipment manual.
