The work aims to develop a high-speed energy-saving lubricating grease filling device. Two filling heads shared quantitative cylinder and feed pipe. The piston divided the quantitative cylinder into two cavities corresponding to two filling heads. The three-way valve installed in each pipeline was connected to the quantitative cylinder, feed pipe and filling head. Under the control of two three-way valves, the piston moved within the quantitative cylinder driven by the material’s pressure in the feed pipe, so as to achieve the alternating filling of two filling heads. The self-driven alternating filling was not required to provide additional driving force for filling, which reduced the production cost, improved the filling speed and guaranteed the product quality. The self-driven lubricating grease filling device has truly achieved high speed, energy saving, simple structure and easiness to control; and it has great promotional values in the field of viscous material filling, such as grease.
