Installation of Automatic Dual Line Lubrication System Products

Installation of Automatic Dual Line Lubrication System Products

CISO dual-line lubrication systems should be installed on easily accessible positions of the machine. Connect the two main supply lines to the change-over valve, which alternately pressurizes each line. Mount dual-line metering devices in branch lines as close to lubrication points as possible. Install end-of-line pressure switches at the farthest point on each main line to monitor system pressure and trigger automatic line changeover. All pipelines must be rated to withstand the maximum pump pressure of up to 400 bar.

Dual Line Lubrication Systems FAQs

Q How does a Dual Line Lubrication System work?
A dual-line system uses a high-pressure pump to supply lubricant alternately through two main lines via a change-over valve. When one line is pressurized, the metering devices on that line dispense a precise amount of lubricant to each lubrication point. The change-over valve then switches to the other line, repeating the process. End-of-line pressure switches detect when pressure builds at the end of the active line, triggering the changeover.
Q What are the advantages of a Dual Line system over a Single Line system? +
Dual-line systems are ideal for large installations with many dispersed lubrication points that require different lubricant quantities per point. They operate at higher pressures (up to 400 bar) compared to single-line systems, making them suitable for heavy-duty applications. They also allow individual adjustment of lubricant dose at each metering device without stopping the system.
Q What types of lubricant can be used in a Dual Line Lubrication System? +
CISO dual-line systems are compatible with grease up to NLGI Grade 3 and lubricating oils. The specific lubricant type should be selected based on the requirements of the lubrication points and the operating conditions of the machinery. Consult a lubrication specialist for recommendations specific to your application.
Q How many lubrication points can a Dual Line system serve? +
A CISO dual-line lubrication system can serve hundreds of lubrication points in a single installation, making it suitable for very large machines such as steel rolling mills, paper machines, and large presses. The exact number depends on the pump capacity, line length, and individual lubricant dose requirements at each point.
Q How is a Dual Line Lubrication System monitored? +
The system is monitored using end-of-line pressure switches (EPW) installed at the farthest point of each main line. When the active line reaches the set pressure, the switch signals the control box to trigger the change-over valve. If the pressure is not reached within a set time, the control box generates a fault alarm, alerting operators to a potential blockage or pump failure.

Progressive lubrication systems vs single line lubrication systems vs dual line lubrication systems vs chain lubrication systems

Feature Progressive Lubrication Systems Single-Line Lubrication Systems Dual-line Lubrication Systems Agricultural Machinery Lubrication System
Definition Progressive lubrication system is an efficient lubrication system used for mechanical equipment, providing lubricant progressively to different parts of the equipment to ensure each part receives an adequate amount of lubrication. The lubrication pump automatically delivers lubricant to the lubricant dispenser via a single supply line. Each dispenser serves only one lubrication point and can be adjusted to provide the exact dose of grease or oil required. Dual-line systems can be used on large systems with dispersed lubrication points that require varying lubrication quantities. These systems utilize two main lines that are supplied alternately with lubricant from a high-pressure pump. An automatic lubrication system for agricultural machinery is an intelligent system that provides quantitative and timed lubrication to key components of agricultural machinery. Through a lubrication pump and distribution device, it precisely delivers grease or lubricating oil to each friction point, ensuring stable operation of the equipment even under high loads, dusty, and humid environments. This system can significantly reduce manual maintenance, lower failure rates, and extend equipment life, thereby improving the overall operating efficiency and reliability of agricultural machinery.

Working Principle The lubricant is pumped through the main lines to the progressive distributor with the pump. The lubricant is delivered "progressively" to the friction point. The circulation of a progressive distributor is monitored optically or electrically. The dosing values are impinged on the main line with the pump – dynamically operating metering valves with a pressure surge, static operating dosing elements with slow pressure build-up. These thus transfer the respective quantity of the lubricant to the friction point. During the following relief phase, the lubricant is restacked in the dosing valves for the next lubrication process. CISO dual-line systems can be used on large systems with dispersed lubrication points that require varying lubrication quantities. These systems utilize two main lines that are supplied alternately with lubricant from a high-pressure pump via a change-over valve at up to 400 bar (5,800 psi). Branch lines, along the main lines, are connected with dual-line metering devices to supply a large volume of lubricant to the lubrication points. Within large dual-line systems, end-of-line pressure switches are used to control and monitor the system. Automatic lubrication systems for agricultural machinery deliver oil or grease automatically, periodically, and in precise amounts while the equipment is running. Lubrication pumps driven electrically or mechanically deliver lubricants through distributors or pipes to each lubrication point, keeping bearings, chains, gears, and other critical components well-lubricated, reducing wear and extending service life.
