ALB900 Series Booster Lube (ALB900-20-15)

ALB900 Series Booster Lube ALB900-20-15

Booster lube enables stable oil feeding with a micromist.
[Features]
· Centralized control of multi-point lubrication.
· Through the use of a booster, a pressure that is higher than that of the main air passage can be supplied.
· This difference is used as the mist generating pressure differential. Thus, the pressure drop in the main air passage is minimized.
· Micromist can be constantly supplied by merely adjusting the mist generating pressure differential.
· Oil can be replenished by merely opening and closing the oil filler plug without stopping the air line.
· The condition of the generation of micromist can be checked from the oil filler port.
· Standard accessories: bypass lubrication adapter / ball valve / ball valve.
· Option: float switch.

Operation Control Method

As shown in the diagram below, reverse the position of the function plate of the switching valve for operation control, and place it in the NO position or in the unmarked position. When the control signal is input, select the state of the operation or the stopping of Booster Lube.
NO position: operate at control signal input
Nil position: stop at control signal input
The 100 V AC, 200 V AC, 220 V AC, 24 V DC, or air pilot type specification can be applied to the control signal.

*The position of the function plate at the time of product shipment is Nil.

Air Consumption

This unit uses a booster to generate a mist generating pressure differential. Therefore, the booster consumes and discharges the air.
Data (A) indicates the relationship between this air consumption rate, the set pressure differential, and the pressure of the main air passage (inlet pressure).

Setting of Mist Generation Pressure Differential

Procedure

  • 1. Obtain the air consumption flow rate in the downstream of Booster Lube.
  • 2. Obtain the necessary mist generation pressure differential from data (B).
  • 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 clockwise, 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.

How to Read the Graph

Example: How to obtain the mist generating pressure differential if the flow rate obtained in step 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 (ANR) 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.

Precautions

Caution on Design

*Epoxy resin containing glass fiber and polycarbonate is used in some parts of Booster Lube. These units cannot be used in an environment or in a location that is exposed to synthetic oil, thinner, acetone, alcohol, organic solvents 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.

Piping

*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.

Mounting/Adjustment

  • *When setting the pressure differential, if there is a fluctuation in the operating flow rate, set the pressure differential to the higher flow rate range. If it is set to the lower flow rate range, the mist density could become thinner, leading to poor lubrication.
  • *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.

Maintenance and Inspection

*Before removing the oil filler plug, loosen it two and a half turns to completely release the pressure inside the case. This will prevent the oil filler plug from flying out.

*See the manufacturer's catalog for product information other than the above.
