2. Issue Summary (Field User-Abdel Fattah):
HPS thrust chamber high temp.& mechanical vibration
Issue Details (Field User-Abdel Fattah) - 23-Apr-02 11:53:43
We had installed HPS unit in EGYPT on Aug., 1999.
The client is WATER KING, the claim was high noise & high mechanical vibration so he manually stopped the HPS.
While trouble shooting of the unit on 20 April, 02
I found that the temp of the thrust chamber housing is 60 degree cent. , while the temp. of the ring between the intake and the thrust chamber was 80
degree cent.
the skid supplied without anchoring plates, also I notices that there is a gab between the skid and the concert foundation at the middle and the front of the
skid, I advised to fill these gabs with shims,
Troubleshooting Performed (Field User-Abdel Fattah) - 23-Apr-02 11:53:43
Checking the thrust chamber oil type found it un recommended by REDA, also found that the level of the oil is below the min level,I drained the oil and
found silver metal chips
I filled the gap between the skid and the concert ,I tightened the pump clamp bolts found some of them loosened
After start up the noise decreased but not normal especially at the thrust chamber side, I monitored the temp. of the thrust chamber and the running
amp, the performance of the pump for about 17 continuous running hours ,the temp. of the thrust chamber did not exceed 60 degree cent.,but the temp.
of the sleeve between the intake section and the thrust housing was 80 degree cent.
I need to know why there is a different temp.at both place.

Response to Trouble Shooting Report
I would like to complement the author of the attached report. This is one of the best I have seen. Good job!!! I would like to
add to your report by discussing some of the items.
Work done & Findings
1. The oil was not the REDA oil however this oil would not damage the TC but could make it run hotter.
2. A bad seal caused the low oil level. How fast was the oil leaking out?
3. Good.
4. The silver chips are a major concern. We are probably having a bearing failure. Please replace the TC as soon as possible. If the TC would seize we
could have major damage to the entire unit.
7. The area between the TC and the seal contains the mounting bracket and the seal. Which was hotter? I will discuss the issue as if both were and see if
you concur with my thoughts. There are three possibilities: The pumped fluid is hot, 80 to 90? C. The mechanical seal has foreign material around it and is
not getting enough cooling from the pumped fluid. The seal side bearing or TC oil seal is failing and causing the heating. Since you plan to change out the
TC because of the silver chips in the oil you will be able to find the cause. Since it is not economical to send the old TC back to the OPC please take it apart
and send me digital photos and I will try to explain any questions you may have.
9. The tightening of the skid bolts was a good idea. Did you use a string line to make sure the pump barrel remained straight? When ever you set a new
unit or realign an old one a string line on the pump barrel is required. I have attached the skid installation procedure from the new HPS manual for your
use. Since the TC has been damaged I would expect the noise to be high.
Conclusion
2. The mechanical vibration may have been too high. If my memory is correct this unit has a Murphy vibration switch on it. The calibration of the switch
may have changed over time or the switch may have not been set correctly from the initial installation. The only safe method is to use a vibration meter.
5. I have attached a procedure for replacing the TC increase you do not have one.
Any additional questions please let me know.

Ref. to the response for the trouble shooting report.
Thanks a lot for trhe quick rrply.
Although I have been working at the pump field since 1984 till now about 15 years before REDA in a germany and a japanese factories.especially at the

For point .2
A bad seal cause da low oil level,the leakage was fast.
For point no4
You mentioned that if TC. seized it could be a major damage to the entire system what you mean by that? is there a problem from being running at this
situation till new TC. arrived.?
For point no 7 The pumped fluid temp.is 110 deg. feh. acc. to the data given by the client.but actualy I did not measure it.
I think the mechanical seal has not a foreign materials around it because the fluid entering the intake is filtered thru a filteration system.
I think the seal side bearing or the TC. oil seal failed and causing heating.
for point 9.
I did not use sring line to be sure that the ump barrel is staright could you tell me the tolerance of that.
Ref. to the viberation point could you pls. suggest a type to measure the viberation.?
Should we do alignment by laser instrument when we change the TC. and when we have to do alignment by the laser instrument??.
You mentioned that you have a new HPS. manual can I have a copy??
I ,ll do my best to do a perfict HPS job.
thanks and best regards

Khaled, I have attached two more documents and referenced another ticket with more vibration information on it. The two vibration meters used by REDA
product group are the CSI 1900 (1237916) and the Greentip multimeter (3901959). The local service center may have the CSI instrument. The Greentip is
a excellent meter because it can measure 5 different items. Please go to this web page for complete information http://www.alignment.com/vibrotip.htm.
The new HPS FS Manual has not been approved for distribution. Some of the documents I have given you are from the manual.
