Progressive lubrication systems are used in machine industry to deliver precise amounts of lubricant to different points in a machine. These systems consist of a central pump that supplies lubricant to a series of feed lines, which in turn feed individual lubrication points.
Here’s how the progressive lubrication system works:
Central Pump: The central pump is the heart of the system. It is usually a motor-driven pump that draws lubricant from a reservoir and delivers it through a network of distribution lines.
Feed lines: The feed lines are a series of pipes or tubes that branch out from the central pump and distribute lubricant to the lubrication points. Each feed line has a metering device, typically a piston or plunger, that dispenses a precise amount of lubricant to the lubrication points.
Lubrication points: The lubrication points are the individual parts of the machine that require lubrication, such as bearings, gears, and chains. Each lubrication point is connected to a feed line and receives a precise amount of lubricant through the metering device.
Monitoring: To ensure that the lubrication system is functioning properly, it is important to monitor the flow of lubricant to each lubrication point. This can be done through visual inspections or by using sensors that detect the presence or absence of lubricant.
Distributors
Inlet port: The inlet port is the point where lubricant enters the distributor from the feed line.
Divider plate: The divider plate is a flat disc that divides the lubricant flow into multiple channels. The number of channels on the divider plate corresponds to the number of lubrication points in the system.
Metering pistons: The metering pistons are small cylindrical components that move back and forth inside the distributor. Each piston is connected to a specific channel on the divider plate and is responsible for dispensing a precise amount of lubricant to a single lubrication point.
Return ports: After the metering pistons dispense lubricant to each lubrication point, the excess lubricant returns to the distributor through the return ports. This ensures that the lubricant flow is accurately controlled and that no excess lubricant is wasted.
Outlet port: The outlet port is the point where lubricant exits the distributor and is delivered to the lubrication points.
rogressive lubrication pumps are used in progressive lubrication systems to deliver lubricant to the system’s feed lines. These pumps operate using a series of pistons and pressure relief valves that are designed to deliver lubricant at a consistent flow rate and pressure.
Pumps
Reservoir: The reservoir is the container that holds the lubricant. The pump draws lubricant from the reservoir and delivers it to the feed lines.
Piston assembly: The piston assembly is the heart of the pump. It consists of a series of pistons that move back and forth inside the pump, drawing in lubricant and pushing it out into the system’s feed lines.
Pressure relief valve: The pressure relief valve is a safety mechanism that prevents the pump from generating excessive pressure. If the pressure inside the system exceeds a certain threshold, the relief valve will open, allowing lubricant to flow back into the reservoir instead of continuing to build up pressure.
Check valve: The check valve is a one-way valve that prevents lubricant from flowing back into the pump when it is not in operation. This ensures that the pump is always ready to deliver lubricant to the feed lines when needed.
Drive mechanism: The drive mechanism is what powers the piston assembly. It is usually a motor or an air-operated mechanism that moves the pistons back and forth inside the pump.
How to selecet right progressive lubrication system for your machine?
Identify lubrication points: Begin by identifying all the lubrication points in the machine. This will help you determine the number of feed lines and metering devices needed for the system.
Determine lubricant type and viscosity: Choose a lubricant that is suitable for the machine’s operating conditions, such as temperature, pressure, and load. Consider the lubricant’s viscosity and whether it will flow easily through the distribution lines and metering devices.
Calculate system pressure: Determine the pressure required to deliver lubricant to each lubrication point. This will help you choose a pump and distribution lines that are capable of delivering the required pressure.
Choose the right pump: Select a pump that can deliver the required flow rate and pressure for the machine. Consider factors such as pump size, motor power, and lubricant compatibility.
Select distribution lines and metering devices: Choose distribution lines and metering devices that are compatible with the lubricant type and viscosity, as well as the machine’s operating conditions. Consider factors such as line diameter, material, and number of metering devices needed.
Determine system control method: Choose a control method that is suitable for the machine’s operating conditions and lubrication requirements. This may include manual, electric, or pneumatic control methods.
Installation and maintenance: Ensure that the system is installed correctly and maintained regularly to ensure proper operation and longevity.
