22. GENERAL BREAKDOWNS.
Another way of avoiding incorrect handling of the equipment and to avoid any possible
situation of risk is to know how to detect the source of the more frequent breakdowns, as well
as to know how to solve them. To achieve this, essentially, the operator/user should be
acquainted with:
1. The normal working order of the equipment, with its corresponding sequences of start-
up and stop.
2. The flow diagram of the materials going through the equipment.
3. The appearance of the product perfectly applied and its possible variables.
Since the ultimate aim of the equipment is the correct application and finish of the foam, it
should be the final appearance of this that we should, in the first place, examine to locate any
possible breakdown or anomalies in the application process and, in this way, identify the
material that is missing (Isocyanate or Poliol).
Therefore, the most appropriate procedure to locate breakdowns is as follows:
1. Identify the product missing.
2. Check the pressure gage corresponding to the material that is missing (
q,v ) in such a
manner that if the reading is higher than normal, there is an obstruction problem
between the pressure gage and the point in the chamber where the gun makes the mix.
Conversely, if the reading is lower than normal, there is an obstruction problem between
the pressure gage and the transfer pumps
14 .
3. In the event that the hydraulic pressure in the material that is deficient is higher than
normal, we should start to check for possible causes for the obstruction from the furthest
point away from the unit (gun) and move upstream following this sequence:
I. Gun: 14

Ensure that the product tap is fully open.

Check the cleanliness of the front hole on the mixing chamber.

Check for the extent of cleanliness in the filter grille.

Check the cleanliness of the side hole on the mixing chamber.
II. Hose:

Ensure that the hoses are not blocked.
4. In the event that the hydraulic pressure in the material that is deficient is lower than
normal, we should start to check for possible causes for the obstruction in the furthest
