Precautions Caution on Design Setting of Mist Generation Pressure Differential Warning Mounting/Adjustment Caution Piping Warning Maintenance Warning Data(B) Flow . Mist Generation Pressure Differential Be sure to read before handling. Refer to front matter 43 for Safety Instructions and pages 365 to 369 for Precautions on every series. EX: How to obtain the mist generating pressure differential if the flow rate obtaine in 1. above is 35 m3/min (ANR) and the line pressure (inlet pressure P1) is 0.7 MPa: Extend horizontally from the point at which the flow rate is 35 m3/min to obtain the point that intersects with P1 = 0.7 MPa. Furthermore, extend vertically downward from that point to the point that intersects with the graduation line of the mist generating pressure differential . The value of that intersecting point, which is 0.15 MPa, is the mist generating pressure differential that is sought. 3. The mist generating pressure differential setting is performed by adjusting the adjustment screw. The pressure differential (the difference between the boost pressure and the line pressure) is increased by turning the adjustment screw clolckwise, and decreased by turning counterclockwise. To check the pressure differential, switch and operate the manual switching valve to read the difference between the boost pressure (HIGH position) and the line pressure (NORMAL position) as shown below (the pressure gauge that is connected to the manual switching valve). After completing the setting, set the manual switching valve to the position of the line pressure indication. Do not set the mist generating pressure differential to exceed 0.2 MPa. 1. Epoxy resin containing glass fiber and polycarbonate is used in some parts of the Booster Lube. The Booster Lube cannot be used in an environment or in a location that is exposed to synthetic oil, thinner, acetone, alcohol, organic solvets such as ethylene chloride, chemicals such as sulfuric acid or nitric acid, cutting oil, kerosene, gasoline, or a threadlock agent, etc., because they will be damaged. If installing an air tank, install it upstream of the bypass oil feed adapter. If it is installed downstream, the micromist could be arrested by the air tank, which could lead to insufficient feeding of oil. 1. When setting the pressure differential, if there is a fluctuation in the operating flow rate, set the pressure differential at the higher flow rate range. If it is set in the lower flow rate range, the mist density could become thinner, leading to poor lubrication. 2. To prevent mist from being generated unnecessarily, if there is no air consumption in the main air passage, operate the switching valve for operation control to stop the operation of the booster. 1. Before removing the oil filler plug, loosen it two and half turns to completely release the pressure in the bowl. This will prevent the oil filler plug from flying out. Procedure 1. Obtain the air consumption flow rate in the downstream of the Booster Lube. 2. Obtain the necessary mist generation pressure differential from data(B).
