Dual line grease distributor how does it work
A dual line grease distributor, also known as a dual line lubrication system , The principle of operation of the two-line systemconsists of two half-cycles.lt is a type of centralized lubrication system used to distribute grease or oil to various lubrication pointsin machinery or equipment. In the first half cycle, the lubricant is pumped to the main line (A), which is connected to the exhaustine (B). Afterwards, the lubricant is channelled through a changeover valve to a dispensing valve.lt is commonly used in industrialapplications where multiple lubrication points need to be serviced simultaneously.
The basic principle of a dual line grease distributor involves the use of two main lines that supply lubricant to the lubrication points.Here's how it works:
Lubricant Supply: The system consists of a central pump or lubricant reservoir that stores the grease or oil. This pump is responsiblefor supplying the lubricant to the system This pump is responsible for supplying the lubricant to the system In clude support and
storage components.
Main lines: From the pump, two main lines, often referred to as the "primary and "secondarylines, are connected. These linesare typically made of steel tubing or flexible hoses and are routed throughout the machinery or equipment.
Pistons or Distributors At each lubrication point, there is a piston or distributor unit, These units are mounted on the machineryand connected to the main lines. They are responsible for controlling the flow of lubricant to the lubrication points.The downwardmovement of the pilot piston 4a connects the upper chamber of the main piston 4b with the upper chamber of the pilot piston,and the lower chamber of the main piston with the oil outlet, and the lubricant supplied and delivered enters the upper chambeiof the main piston, pushes the main piston downward, and presses the lubricant in the lower chamber of the main piston throughthe oil feed tube 6 to the lubrication point, and completes the first cycle of the oil feeding action.
Operation: The system operates in cycles, alternating between the primary and secondary lines. When the system is activated, thepump pressurizes one of the main lines (for example, the primary line) while the other line (secondary line) is depressurized.
Lubricant Distribution: As the primary line is pressurized, the pistons or distributors connected to that line are also pressurized. Thiscauses the pistons or distributors to move and distribute the lubricant to the lubrication points.The dispenser piston performs thepreceding actions in the same order and in reverse..
Reversal: After a predetermined time or stroke count, the system reverses the cycle. The pump switches to pressurizing thesecondary line while the primary line is depressurized. This reversal ensures that lubricant is distributed evenly to all lubricationpoints over time.
In addition, the distributor piston two-end screw plug is not allowed to dismantle for no reason, such as leakage should befightened or replaced with a new sealing washer, and the distributor contact surface should be smooth and fat, the mounting boltsshould not be tightened too tightly, so as not to deform the impact of the normal action, in the dusty, humid, harsh environments.should be equipped with a protective cover, and must be in the specifed environment using the prescribed medium.
