Hydraulic equipment repair and maintenance 1. Each boot should empty load running for 2-5 minutes (winter can add time, not less than 30 minutes), before it can function. 2. The new equipment in the future need to use one week once all the oil filtration and tank cleaning small mixer, and then loads the machine according to the work, 3-6 months to replace a fluid lacquer mixer, a tank cleaning. 3. Use of the process is prohibited because the system will heat and the fuel tank cap or filling hole open. Pressure gauge switch mixer picture after adjustment is completed, turn off the (long-term open gauge switch prohibit mixer, damaging the gauge). 5, prohibited outdoor use, measures should be rain in 1795, British J. Brammer application Pascal principle invented the hydraulic press, for packaging, pressed vegetable oil. By the mid-19th century, Britain began to hydraulic press for forging hydraulic press then gradually replaced the large steam hammer. The 19th century, the United States made 126,000 KN free forging hydraulic press. Since then, the world has more than 20 manufacturing 10 million cattle class free forging hydraulic press, which made in China have two (see pictures). With the emergence of electric high-pressure pump and perfect, forging hydraulic press is also developing the small-tonnage direction. After the 1950s, the emergence of small, fast forging hydraulic press, can be equivalent to working 30 to 50 kN hammer made. 1940s, Germany made 180,000 kN giant forging hydraulic press, after which the world has made more than 180 000 kN forging hydraulic machine 18, which China made a 300,000 kN.
