For the wide range of Applications of hydraulics, high temperature cooling of hydraulic oil is the key to ensure the good operation of the equipment. We have accumulated a lot of experience in design calculation and production in the 20 years of hydraulic oil cooling. Whether the unit is a Hydraulic Oil Cooler or a hybrid hydraulic Oil Cooler, we can individually customize the product according to the individual needs of the customer's industrial hydraulic equipment. At the same time, we also offer a standard hydraulic oil cooler series solution to ensure the performance at the same time. Avoid long-term problems with separate designs, and we offer different cooling drive methods for different application areas, such as hydraulic motors, DC motors, AC motors, explosion-proof motors, pneumatic motors, etc.
Hydraulic technology is also used in solar tracking systems, wave simulation devices, ship driving simulators, seismic reconstruction, rocket-assisted launching devices, aerospace environment simulations, and high-rise building anti-vibration systems and emergency braking devices.

The annual production capacity of 800,000 tons of PTA plant is the first of 100 construction projects for the revitalization of Northeast Old Industrial Base, the first approved petrochemical project, and also the key project of China Petroleum's “Eleventh Five-Year†refining business structure adjustment. In order to solve the sewage treatment problem, Liaoyang Petrochemical has set up a sewage pretreatment workshop and has built up seven sewage treatment pools. The daily processing capacity reaches 9,600 tons, which fully meets the needs of equipment for sewage and pollution control, and makes the COD value of the discharged wastewater complete. Up to standard.
The company's environmental protection concept is also reflected in many details of the new device design. Taking an exhaust tower of a refinery as an example, the original emission of steam was 17 tons per hour, and the capacity of the new plant was doubled. The steam discharge per hour was only 2 tons. The new high-pressure exhaust gas incineration system treats the carbon monoxide contained in the exhaust gas during the treatment of the exhaust gas, eliminating the pollution of the exhaust gas to the environment, saving both the upstream production raw materials and the downstream pollutant treatment pressure.
In the silo recovery system, the company specially designed a rainwater effluent pool, which not only fully recovers the effluent materials, but also reduces the sewage treatment pressure. Under the severe situation of depletion of water resources in Liaoyang region, this device not only effectively prevented water pollution, but also changed the rain given by nature into a “babyâ€.
Because hydraulic technology has many outstanding advantages, it has been widely used from civilian to national defense, general transmission to highly accurate control systems. In the defense industry. Many of the weapons and equipment of the Air Force have adopted hydraulic transmission and control. Such as airplanes, tanks, ships, radars, artillery, missiles and rockets. In the machine tool industry, 85% of the current machine tool transmission systems use hydraulic transmission and control, such as grinding machines, milling machines, planers, broaching machines, presses, shearing machines and combination machine tools.
In the metallurgical industry, electric furnace control systems, rolling mill control systems, open hearth charging, converter control, blast furnace control, strip deviation and constant tension devices all use hydraulic technology. In construction machinery, hydraulic transmissions such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibratory rollers are commonly used.
In agricultural machinery, hydraulic technology is also widely used, such as combine harvesters, tractors and plows. In the automotive industry, hydraulic off-road vehicles, hydraulic dump trucks, hydraulic aerial work vehicles and fire trucks all use hydraulic technology; in the textile industry, plastic injection molding machines and rubber vulcanizers are used. Paper machines, printing presses and textile machines; in the marine industry, the application of hydraulic technology is very common, such as full hydraulic dredgers, salvage boats, piling boats, oil production platforms, hydrofoil ships, hovercrafts and ship auxiliary machines. recent years.
Liaoyang Petrochemical Company's refined terephthalic acid (PTA) plant was expanded from 270,000 tons per year to 800,000 tons per year. The project has been completed recently. The current installation has been safely and steadily operating for 40 days, producing a high quality PTA of 51,700 tons. After the industrial waste water is purified twice, the COD value of the effluent is much lower than the design index, and the exhaust emission reaches the Euro III standard, achieving “zero emissionâ€.
