Abstract
The invention discloses a pure water hydraulic drive system of a lifting platform. Deionized water is used as a hydraulic transmission medium. The pure water hydraulic drive system comprises a water pressure piston cylinder, a three-position four-way electromagnetic reversing valve, a proportional valve, an energy accumulator, a check valve, a hydraulic control check valve, a plunger water pump, a variable frequency motor, an overflow valve, a filter and a water tank. The movement state of the hydraulic cylinder is regulated in real time through the three-position four-way electromagnetic reversing valve and the proportional valve, and the movement speed of the lifting platform is precisely controlled. For the heavy load requirement of the lifting platform, the energy accumulator is used as an auxiliary power source, an energy accumulator unloading loop is designed, and the service life of the energy accumulator is prolonged while the installed power of the system is lowered. By means of the pure water hydraulic drive system, the pure water hydraulic technology is applied in the lifting platform, the special loop is designed for the specificity of water pressure components, and the pure water hydraulic drive system can be widely applied to high-temperature open fire radiation places and various lifting platforms under the flammable and combustible pollution-free environments and other environments.
