KS20B-B Portable Emulsion Liquid Mobile Pump Station (also known as the manual rapid lifting column for emulsion liquid) is a manually variable speed, quick and convenient tool specifically designed for the coal industry support system. It optimizes the valve body on the basis of the KS20B-A model, achieving a pressure of 28MPa. Mainly used for irregularly sized coal faces in the head of pit mining in areas without supply, for rapid lifting of single hydraulic props and testing the pressure of single hydraulic props during tunnel repair; as well as for rapid lifting of props in other areas without supply, and for emergency rescue operations, it is a small machine essential for the safety production of the coal industry. The emulsion liquid rapid lifting column uses a dual valve body design: it consists of manual variable speed, large piston supply, and small piston pressure increase; it is quick, lightweight, time-saving, and labor-saving, making it a convenient, safe, and reliable lifting tool.
