Custom Hydraulic Cylinders for Metallurgical & Heavy Machinery

Tianjin Uranus Hydraulic Machinery Co., Ltd. provides custom hydraulic cylinders for the renewable energy sector, specifically for concentrated solar power (CSP) plants and hydrokinetic turbines. As a national intellectual property advantage enterprise with over 30 years of hydraulic experience, we design cylinders that operate reliably in high-temperature, high-radiation, or underwater environments. For CSP plants, our custom cylinders are used to position heliostats (mirrors) to track the sun. These cylinders must have very low power consumption (to allow solar-powered operation) and high precision. We use low-friction seals, lightweight aluminum construction, and integrated magnetic position sensors. For a Spanish CSP plant, we supplied over 1,000 custom heliostat cylinders with a stroke of 500 mm and a positioning accuracy of ±0.5 mm. The cylinders are designed for a 25-year service life and have been operating for over 8 years. For hydrokinetic turbines (underwater turbines that generate power from river or tidal currents), we provide custom cylinders for blade pitch control and yaw systems. These cylinders must be completely sealed against water ingress and operate at depths up to 50 meters. We use pressure-balanced seals, corrosion-resistant alloys (super duplex stainless steel), and we fill the cylinder with a biodegradable hydraulic fluid. For a Canadian hydrokinetic turbine developer, we supplied custom pitch control cylinders that have been submerged for over 5 years with no maintenance. For geothermal power plants, we provide custom cylinders for valve actuation and wellhead equipment. These cylinders must withstand high temperatures (up to 150°C) and corrosive brines. We use high-temperature seals (Kalrez), and the cylinder body is made from Inconel or Hastelloy. For a New Zealand geothermal plant, we supplied custom cylinders that have been in service for over 7 years in a 130°C environment. Our manufacturing process includes salt spray testing for corrosion resistance, and for underwater cylinders we perform a pressure test in a water tank.
