Description

Pero V4 Enclosed Ultrasonic & Vapour Degreasing Machine

Functional Description

The cleaning unit supports 50 freely selectable and 20 freely programmable washing programmes.

From the washing programme steps listed below, a complete washing programme can be compiled. The order of the steps has to be useful for the purpose.

Washing programmes are preferably based on previously completed trials or trial carried out during commissioning.

Compiled washing programmes can be changed or rewritten at any time through the edit programmes menu.

Useable dimensions: 856 x 1208 x 515 mm

Description of Baths 1 & 2

Bath 1 is used to pre-wash the parts.
In cleaning units equipped with a tank and a conservation unit, the tank for bath 1 is continuously supplied with solvent distillate (internal distillate cycle of cleaning unit).
In cleaning units equipped with two baths, the distillate cycle first supplies bath 2, then bath 1 and finally returns the distillate to the vapour generator.

Bath 2 is used to rinse the parts.
The tank for bath 2 is continuously supplied with solvent distillate (internal distillate cycle of cleaning unit).

Washing programme Bath 1 / Bath 2

Bath

• The processing chamber is filled.
• The parts are processed for the set processing time.
• The processing chamber is emptied.
• Bath washing is completed.

Flooding

• The processing chamber is filled.
• The flooding intervals (emptying filling) are repeated according to the set cycle runs.
• The processing chamber is emptied.
• Bath washing is completed.

Splash Flooding

• The processing chamber is gradually filled in stages.
• Distillate is pumped off, until the set number of intervals is completed.
• The processing chamber is emptied.
• Bath splash flooding is completed.

Ultrasonic

The processing chamber is filled.
• The parts are processed for the set processing time. Simultaneously, the ultrasound unit is on, while a vacuum is established in the processing chamber.
• The processing chamber is emptied and the ultrasonic unit is switched off.
• Bath washing is completed.

Vapour Degreasing

Description

. Solvent vapour streams from the vapour generator into the processing chamber.
• The solvent vapour condenses on the cold parts in the processing chamber.
• The parts are thoroughly degreased.

Washing Programme

Vapour Degreasing

• The vapour check valve opens.
• Solvent vapour flows into the processing chamber.
• The parts are processed for the set processing time.
• If the parts are hot and the set temperature at B604 is reached, the vapour check valve closes.
• Steam degreasing is completed.

Oiling / Preservation Bath

Description

In the preservation bath, the degreased parts are preserved.

Washing programme

Preservation

• The parts in the processing chamber are dried.
• The processing chamber is filled.
• The parts are processed for the set processing time.
• The processing chamber is emptied.
• The oiling (preservation) process is completed.

Vacuum Drying

The parts are dried prior to leaving the processing chamber.

Drying Programme

Vacuum drying 1

• The vacuum in the processing chamber is measured.
• The set vacuum pressure value in the processing chamber is reached.
• The system switches to drying using vacuum 2.
• Vacuum drying is completed.

Vacuum drying 2

• The vacuum pressure in the processing chamber is measured.
• The set vacuum pressure value in the processing chamber is reached.
• Vacuum drying is completed.
• Depending on the parts to be dried, vacuum drying can be repeated several times.

Vapour Generator

Function of the vapour generator:

• Production of solvent vapour for the
- heating of baths,
- cleaning (vapour degreasing) of goods in the processing chamber.
• Cleaning of the solvent by means of distillation (residual distillation). The distillation process is a thermal cleaning method used to remove contaminants and process chemicals from the solvent.

Principle of residual distillation

The residual distillation function must be activated manually on the control panel.
During residual distillation, the solvent mixture is heated in the vapour generator for separation into different fractions.
The solvents supply to the cleaning unit is thereby discontinued. The temperature and vacuum are continuously monitored.
The solvent evaporates during the heating-up phase.
The produced solvent distillate is condensed in the condenser and subsequently returned to the rinsing bath (option) and then to the washing bath (cascade).
The contaminants remain in the vapour generator forming a residual/distillation sump (residue of oil and other substances with high boiling point).
The residual sump is manually removed from the vapour generator.

Filters

Working principle

Filtration of the solvent in the main flow behind the exit of the processing chamber. Each bath (tank) has its own filter.

• The filtration process is a mechanical cleaning method separating solids from the solvent.
• The solvent is sucked through the filter or forced through the filter by pressure.
• The solids held back on the surface of the filter are referred to as the filter cake.
• As the filter cake grows, the solvent flow is obstructed and a differential pressure occurs in front of and behind the filter. To prevent this, the filter must be regularly dried and cleaned.

Filter drying function
The filter drying function must be activated manually on the control panel.

Bypass filtration function
If bypass filtration is switched on, the content of the bath is continuously pumped through the filter, depending on the preselection

Condenser
The solvent vapour produced in the vapour generator is condensed in the condenser.
The resulting distillate is fed to the water trap. From there, the solvent is pumped to the bath.
The condenser is water-cooled.
Adjust the cooling water flow at the flow monitors.

Water trap
The distillate from the condenser and from other distillate lines is fed to the water trap.
In the water trap, the water is removed from the distillate to obtain pure solvent.
When the maximum filling level is reached, the solvent distillate is released from the vessel and pumped to the bath.

Water Sensor 8810
As soon as the sensor detects water, this is drained off to the separated water tank.

Cathode Protection
The water trap is equipped with a zinc plate protecting the cathode (galvanic anode).
Due to its properties, the zinc plate is first corroded by acids before any damage is done to the cathode.
If the zinc plate is destroyed, the stainless steel of the cathode is exposed to attack by pitting corrosion.

Dryer 4
The air containing solvent is fed through the vacuum pump to the dryer 4. In the dryer, the air is constantly thawed.
The dryer is water-cooled. The dryer is air-cooled.

Function "Energy saving mode"
By running the cleaning unit in energy saving mode, you can reduce the power consumption, as the heating output of the unit is reduced.
In addition, the amount of cooling water is also reduced.

Working principle
In energy saving mode, the energy saving is activated with a delay of 30 minutes after the cleaning unit has been heated up o after the last washing cycle.
If energy saving mode is activated, the total heating output is reduced.
This is done by adjusting the pressure value (valve K49).
When the washing cycle is started, the energy saving function is deactivated.
When run in energy saving mode, the amount of distilled solvent in the prewash bath is reduced.
