Measurement and Study of Pulsation Ratios and Vacuumphase Ratios of Piston Milking Machine

The pulsation ratios, maximum and minimum vacuum phase ratios of a piston milking machine were measured and analyzed by means of modern measurement technique under unloading and loading. The studying results indicate that the pulsation ratios and minimum vacuum phase ratios of the piston milking machine measured and studied meet the standard, but the maximum vacuum phase ratios are lower than those of the standard. It is important to improve the piston milking machine.
