 Nozzle
Knowledge |
Keep
the following suggestions in mind when selecting a nozzle
for your jetting operations:
- THE
LESSER DEGREE NOZZLE HAS A GREATER THRUST OR ROCKET POWER
THAN THE HIGHER DEGREE NOZZLE.
For
example: Because a 15 degree nozzle has more thrust than
a 35-45 degree nozzle, it can move straight ahead faster
and therefore is better equipped to get through an obstruction.
- THE
HIGHER DEGREE NOZZLE HAS MORE CLEANING POWER THAN THE
LESSER DEGREE NOZZLE.
For
example: Because of the orifice design of a 35-45 degree
nozzle, the water scours the sides of the sewer pipe and
gives this nozzle the ability to clean walls of the sewer
line. The 15 degree nozzle does not clean as efficiently
because of its orifices are angled toward the rear of
the sewer line.
PICTURE
OF 15 DEGREE NOZZLE AND 35-45 DEGREE NOZZLE
-
A NOZZLE
DESIGNED WITH A FRONT ORIFICE SHOULD BE USED IN ALMOST ALL
PLUGGED SEWER LINE CASES.
- THERE ARE SOME NOZZLES DESIGNED THAT HAVE 15 AND 35
DEGREE ORIFICES. THESE NOZZLES ARE HIGHLY RECOMMENDED
WHEN CLEANING IS NECESSARY PRIOR TO TELEVISING.
- NOZZLES EVENTUALLY WEAR OUT. AS THE NOZZLE WEARS OUT,
THE HOLE SIZE OF THE ORIFICE INCREASES. DECREASE IN PRESSURE
IS OFTEN CAUSED BY THE NOZZLE ORIFICES GETTING TOO LARGE.
THIS CAN CREATE PUMP AND ENGINE PROBLEMS. KEEP NEW NOZZLES
ON HAND AND USE THE PROPER NOZZLE FOR EACH SEWER CLEANING
PROCEDURE.
