Continuous Lubrication Systems are designed primarily for internal lubrication, for example gearboxes, where splash or oil ring lubrication techniques provide inadequate lubrication for the entire gear train. Various types of pump may be used, mechanical or electrically operated are available, giving a range of output deliveries and pressures to suit each application.
Oil flow to individual points is normally controlled by adjustable needle valves or by using the fixed type capillary “CONTROL” meter units (as shown in the “Proportional System” section of this catalogue). It is also possible to use the divider block type Progressive Distributors, when using the higher-pressure pump system. (Details of Progressive Distributors will be found in the ‘Progressive Systems’ section of this catalogue). Oil supply for the Continuous System can be from the machine sump or gearbox, alternatively an external independent reservoir. When used as a re-circulating system provision must be made for an oil strainer on the suction side of the pump that has an adequate surface area.
