3300X53 Series
Applications
- Lubrication of all those elements in which the dispenser is in contact with sea water, dredgers, submarines, etc… in general any type of lubrication in the naval industry.
Features
- Block design to avoid leakage.
- Can be used with grease and oil.
- Made of highly corrosion resistant material.
- Adjustable flow rate.
Description
The metering units are lubrication elements designed for two simultaneous supply lines, one of them being pressurized and the other depressurized. The lubrication cycles are alternated, thus dosing an adjustable quantity of lubricant in each cycle.
Design and principle of operation
Designed in aluminum alloy and bronze EN 1982 – CuAl10Fe5Ni5-C resistant to marine waters in the worst conditions, including surface waters that are much more oxygenated.
Each metering unit is composed of a servo piston and a servo piston (A) and a servo (B). The piston movements illustrated in Fig. 1 show the operation of the dispenser alternating the lubricant feed when it enters through line 1 or when it enters through line 2,
The supply is made with the two separate outlets, but there is the possibility of internal communication of the outlets unifying them into a single outlet, thus doubling the flow rate. As the communication is internal, we offer the advantage of avoiding external piping and fittings, thus favoring a clean installation.
Installation
They are placed in double lines along the entire installation in the areas closest to the greasing zone. The number of dispensers to be installed depends on the length of the installation and the points to be greased.
Installation of metering units line 1
The grease or oil coming from the pump through line 1 is pressurized into the valve; it displaces the servo leaving a passage towards the injector, displaces the latter in the same direction, fills the entire chamber with lubricant and at the same time injects the lubricant stored on the opposite side to the lubrication point.
Installation of dosing units line 2
When all the plungers of the installation have moved, the pressure in pump and inverter reaches that which was set and determined, then switch the inverter to line 2 and leave line 1 in return, where the pressure drops to zero. The pump through line 2 introduces the lubricant into the metering valve and displaces the injector to lubricate the opposite side.
