GLOSSARY |
For the maximum operation of the EPS mould machines of the latest technology
that incorporate vacuum pumps, the water temperature plays a very important
rule.
The vacuum pumps need a water temperature between 26-30ºC for the function
and the refrigeration of the pumps, to obtain 0,6-0,7 Kg/cm2 vacuum level.
The refrigeration of the installed moulds should be done with water at a temperature
range between 50-60º, to allow mouldings drying and cooling due to the
water vaporization effect that produces to the vacuum in the chambers.
In order to obtain the maximum temperature of the vacuum pumps around 30ºC
and at the same time the temperature for the moulds refrigeration around 55ºC,
two separated water-feeding systems are recommended. The circuits design,
have as basis the discontinuous consumptions on each one of the equipments
and the coincidence in time of such consumptions.
The returned water with the condensate steam is done through a common pipe.
