Dual-line Lubrication Systems

Dual-line Lubrication Systems

CISO autmotic dual-line systems can be used on large systems with dispersed lubrication points that require varying lubrication quantities. These central dual line lubrication 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 centralized dual line lubrication systems.

ZP01/02 Lubrication Pump
The ZP01/02 pumps, known for their high-pressure and high-volume capabilities, can function as supply pump units for small to midsize dual-line systems or progressive systems.
ZP08/14/24 Lubrication Pump
Primarily utilized in dual-line systems or as supply pumps, the ZP08/14/24 pumps operate at a maximum pressure of 400 bar (5 800 psi).
DSG Dual-line Metering Devices
Designed for dual-line systems with pressures up to 400 bar (5 800 psi), the robust DSG metering devices, made from galvanized steel, are available with up to eight outlets. Each pair of outlets features an indicator pin for visual inspection.
DSL Dual-line Metering Devices
The DSL metering devices, crafted from durable galvanized steel, are designed for dual-line systems and can withstand pressures up to 400 bar (5 800 psi). These devices, available with up to eight outlets, feature an indicator pin on each pair of outlets for visual monitoring.
WP-C Electric Change-Over Valve
The WP-C Electric change-over valve, an integrated detention control device, utilizes a high-torque DC deceleration motor to drive the movement of the valve sliding core. This movement opens and closes the oil supply pipeline or alters the direction of the oil supply.
DU-C Hydraulic Change-Over Valves
Primarily designed for dual-line lubrication systems, DU-C hydraulic change-over valves alternately discharge lubricant from the pump into one of the two main lines. The other line is linked to the pump’s return line connection. The switching pressure of these valves is adjustable.
MC-ⅠSystem Control Box
The MC-Ⅰcontrol equipment is specifically designed for managing and controlling a centralized lubrication system. The dedicated card installed within the equipment controls the system’s entire inlet and outlet signals.
EPW End-of-line Pressure Switches
EPW end-of-line pressure switches, crucial components in a dual-line lubrication system, are designed to oversee the system. They identify the pressure at the end of the respective main line and initiate the change-over procedure.

Attention of Autmotic Dual Line Lubrication System Products

Attention of Autmotic Dual Line Lubrication System Products
  • Do not install or remove the metering devices when the system is under pressure or the pump in operation.

  • Always protect the centralized dual line lubrication systems connected to the pump with a pressure reducing valve.

  • lncorrect operation may lead to damage resulting from insufficient or excessive lubrication of bearings or lubrication points.

  • Your own alterations or modifications of installed automatic dual line lubrication systems should only be carried out if approved with the manufacturer or his appointed dealer. Contact Cisolube centralized grease lubrication system for detailed information.

For all work at the metering device, observe extreme cleanliness. 

  • Attach the metering devices to even surfaces without tension. When base plates are used, first weld the base plates without the metering devices and then attach the metering devices onto them.

  • Protect the metering devices from dust and influences of heat (observe the maximum admissible operating temperatures).

  • The metering devices must be easily accessible for . check and installation work.

  • Before connecting the feed lines to the metering devices, fill them with lubricant.

  • when connecting the main lines take care to always connect the same line (l or ll) to the same metering device inlet. 

  • This makes it easier to check of the metering device because all indicator pins are either in or out after each cycle.

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 Chain Lubrication Systems
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.

Chain lubrication system is a system used to protect and maintain chains of mechanical equipment. It works mainly by providing the right amount of lubricant to reduce chain friction and wear, and to maintain chain flexibility and operating efficiency. A chain lubrication system usually includes a tank, lines, and brushes. These components work together to ensure that the chain surface is always properly lubricated, prolonging the life of the chain and drive system, reducing maintenance costs, and improving equipment reliability and efficiency.

Working Principle

The lubricant is pumped through the main lines to the progressive distributor with the pump. The lubricant is elivered "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.

The chain lubrication system transfers the lubricant from the storage tank to the brushes through the lubrication pump, and through the brushes the lubricant is applied to the chain to form a lubricating film, which reduces the chain friction and wear.
