KS20B-B Portable Emulsion Liquid Mobile Pump Station (also known as the manual rapid hoisting column for emulsion liquid), is a manually variable-speed, quick and convenient liquid injection tool specially designed for the support system in the coal industry. It optimizes and improves the valve body based on the KS20B-A model, achieving a pressure of up to 28MPa. Mainly used for irregular coal surface mining at the heading of pit mouth excavation in areas without supply, and for rapid hoisting and hydraulic支柱 testing during tunnel repair; as well as for rapid hoisting in tunnels without supply and other emergency rescue operations, it is a small machine essential for the safety production of the coal industry. The emulsion liquid rapid hoisting column features a dual valve body design: utilizing manual variable speed, large piston supply, and small piston pressure increase; it hoists quickly, is lightweight, time-saving, and labor-saving, making it a convenient, safe, and reliable hoisting tool.
