GM-SSP series plate type hydraulic screen changer
Why this GM-SSP series slide plate type hydraulic screen changer is called Semi continuous screen changer ?
The semi-continuous hydraulic slide-plate screen changer utilizes a fast-acting hydraulic cylinder to move the screen packs in and out of the melt flow. These kinds of units can be defined as semi-continuous because they allow screen changing without stopping the line, but during that process some off-specification material will be produced.
The advantages to this type of unit are relatively low cost, straight-through, low-pressure loss design, and screen changing without stopping the line. The hydraulic slide plate is a low-cost way to provide screen changing "on the fly" with the disadvantage being the production of some off-spec material due to momentary interruption and air entrainment.
This GM-SSP series plate type hydraulic screen changer now is widely used on the corrguated pipe extrusion machine ,usually , on the corrguated pipe installs two sets of this kind of screen changer to filter the inner wall and the outer wall at the same time, and this two sets of screen changer can be controlled by one set of hydraulic unit.
And it can also be used for everywhere need filtration.And the proven technology and reasonable price make it popular in all over the world, it is a basic filtration tool on the extruder, and nowdays, as the develops of technology, more and more people begin to use some other kind of continuous screen changer to instead of this type, such as our double piston continuous screen changer.
Main features of this plate type hydraulic screen changer
1)Quick/fast
1.1,To move from the filtering screen in the working position to the clean screen takes only a minimum time, less than 2 seconds
1.2,Extraction and replacement of the filtering screens take place very quickly and maintenance can be carried out in a short time
1.3,The speed of the change from one screen to the other means that the action of the extruder is not interrupted
2)Flexible
2.1,This kind of plate type screen changer can be installed vertically, horizontally ,or slantly, and the hydraulic cyclinder can be on the right side or left side , or vertical.
2.2,Serveral sets of screen changer can be drived by one set of hydraulic unit.
3) Safe
4)The screen changer is provided with several devices which guarantee its safe use.
5)The safety blocking system of the doors and the hydraulic unit protects from the movements of the plates and from accidental opening during maintenance
6)The block of the accumulator prevents the hydraulic unit to exceed the adjusted maximum pressure
7)guarantee a perfect seal during the sliding of the plates
