yale hydraulic pump made in china

I have an older maybe 15 years old LP powered Yale forklift I use at my hobby shop. When I found it/bought it a year ago the previous owner said the engine was locked up. I got it home and worked the flywheel back and forth and got it to turn over. I was even able to get it running with no knocks or noises. Here it is a year later being used 2-3 times a week and it started making a whine noise while lifting which seemed slower and over a few days completely lost all hydraulic action to the mast. I do hear the whine noise and it gets louder with engine rpm. No movement on the mast whatsoever at any engine speed BUT I do have steering ( with the whine in sync with the turning of wheel). It sounds like the hydraulic pump is low on fluid but it is full of fluid and it looks aerated. I changed the filter and still did it. First thought was the hyd pump went bad and maybe that what was locked up a year ago. Any Yale gurus out there have any tips before I pull the hyd pump? Thanks

Americans like to celebrate successful entrepreneurs who started out with little more than the shirt on their back. But most of us have never heard of Liping Wong. Like a Steve Jobs of the fluid-power world, Mr. Wong started out making pneumatic cylinders in his garage near Shanghai with just two employees. Twenty-five years later his company, Hengli (www.hengli-js.com) is a $2 billion powerhouse in China and reportedly the world’s largest producer of hydraulic cylinders.

In 2009, Hengli built what’s considered the largest hydraulic cylinder production facility in the world, with an annual capacity of 500,000 pieces. More recently it acquired Shanghai Lixin Hydraulic Co., a well-established hydraulics manufacturer capable of turning out 1.5 million valves per year, and it developed a line of piston pumps. That opened the door to complete systems capabilities.

It’s part of Mr. Wong’s vision to make Hengli a worldwide brand, explained Justin Fluegel, general manager of Hengli America. Today, there is no Chinese equivalent of a Rexroth, Parker or Eaton recognized across the globe as a source of high-quality hydraulics. His goal is to change that. With sights on international expansion, three years ago they opened a Chicago office to focus directly on the U.S market.

The historical region now known as China experienced a history involving mechanics, hydraulics and mathematics applied to horology, metallurgy, astronomy, agriculture, engineering, music theory, craftsmanship, naval architecture and warfare. Use of the plow during the Neolithic period Longshan culture (c. 3000–c. 2000 BC) allowed for high agricultural production yields and rise of Chinese civilization during the Shang Dynasty (c. 1600–c. 1050 BC).multiple-tube seed drill and the heavy moldboard iron plow enabled China to sustain a much larger population through improvements in agricultural output.

For the purposes of this list, inventions are regarded as technological firsts developed in China, and as such does not include foreign technologies which the Chinese acquired through contact, such as the windmill from the Middle East or the telescope from early modern Europe. It also does not include technologies developed elsewhere and later invented separately by the Chinese, such as the odometer, water wheel, and chain pump. Scientific, mathematical or natural discoveries made by the Chinese, changes in minor concepts of design or style and artistic innovations do not appear on the list.

Philon of Byzantium (3rd or 2nd century BC)chain drive and windlass used in the operation of a polybolos (a repeating ballista),chain pumps which had been known in China since at least the Han Dynasty (202 BC – 220 AD) when they were mentioned by the Han dynasty philosopher Wang Chong (27 – c. 100 AD),clock tower built at Kaifeng in 1090 by the Song Chinese politician, mathematician and astronomer Su Song (1020–1101).

Escapement, hydraulic-powered (use in clock tower): The escapement mechanism was first described for a mechanical washstand by the Greek Philon of Byzantium who also indicated that it was already used for clocks.Yi Xing (683–727) of the Tang Dynasty (618–907) for his water-powered celestial globe in the tradition of the Han dynasty polymath and inventor Zhang Heng (78–139), and could be found in later Chinese clockworks such as the clock towers developed by the military engineer Zhang Sixun (fl. late 10th century) and polymath inventor Su Song (1020–1101).striking clock.pendulum resting and releasing its hooks on a small rotating gear wheel, the early Chinese escapement employed the use of gravity and hydraulics.waterwheel (which acted like a gear wheel) would be filled one by one with siphoned water from a clepsydra tank.

air conditioning, the Han Dynasty craftsman and mechanical engineer Ding Huan (fl. 180 AD) invented a manually operated rotary fan with seven wheels that measured 3 m (10 ft) in diameter; in the 8th century, during the Tang Dynasty (618–907), the Chinese applied hydraulic power to rotate the fan wheels for air conditioning, while the rotary fan became even more common during the Song Dynasty (960–1279).Georg Agricola (1494–1555).

archaeological site in Anatolia (Kaman-Kalehoyuk) and is about 4,000 years old.East Africa, dating back to 1400 BC.Falcata were produced in the Iberian Peninsula, while Noric steel was used by the Roman military.cast iron from the late Spring and Autumn period (722–481 BC), produced steel by the 2nd century BC through a process of decarburization, i.e. using bellows to pump large amounts of oxygen on to molten cast iron.Liu An (179–122 BC). For steel, they used both quenching (i.e. rapid cooling) and tempering (i.e. slow cooling) methods of heat treatment. Much later, the American inventor William Kelly (1811–1888) brought four Chinese metallurgists to Eddyville, Kentucky in 1845, whose expertise in steelmaking influenced his ideas about air injection to reduce carbon content of iron; his invention anticipated the Bessemer process of English inventor Henry Bessemer (1813–1898).

pestle and mortar to pound and decorticate grain, which was superseded by the treadle-operated tilt hammer (employing a simple lever and fulcrum) perhaps during the Zhou Dynasty (1122–256 BC) but first described in a Han Dynasty (202 BC – 220 AD) dictionary of 40 BC and soon after by the Han dynasty philosopher and writer Yang Xiong (53 BC – 18 AD) in his hydraulic power, which the Han dynasty philosopher and writer Huan Tan (43 BC – 28 AD) mentioned in his Xinlun of 20 AD, although he also described trip hammers powered by the labor of horses, oxen, donkeys, and mules.waterwheels were made in subsequent Chinese dynasties and in Medieval Europe by the 12th century.Pliny, Roman Empire by the 1st century AD.
