For the maintenance of multistage pump, if conditions permit, first look at the manufacturer's maintenance manual and general assembly drawing to see what special areas need attention.
I During disassembly:
1. Before removing the thrust bearing, use a dial indicator to measure the clearance of the balance disc and make records;
2. When disassembling the multi-stage pump, all parts must be marked according to the original matching sequence to avoid confusion and wrong installation during reassembly;
3. Small parts (such as keys) that are not easy to mark can be placed together with impellers or guide vanes (middle section) at the same level.
4. During disassembly, you can intuitively feel whether there are abnormal parts, such as loose fitting, etc.
II Parts maintenance:
1. Visually check whether the surface of all parts is normal, and all mating surfaces must be free of collision, scratch, corrosion, etc;
2. Measure whether the tolerance of key mating parts is qualified with measuring tools;
3. Measure whether the clearance of impeller seal ring, shell seal ring, guide vane seal ring, interstage shaft sleeve, etc. is within the tolerance range. If the wear is too large, it needs to be replaced;
4. Check whether the bearing is intact;
5. All sealing rings and gaskets shall be renewed; Submersible pump
1. Install the rotor and conduct dynamic balance test again;
2. Reassemble all parts in the reverse order of removing the pump. During reassembly, pay attention to measure the clearance value at each sealing ring again to ensure that there is no error;
3. Before installing the balance disc, measure the total amount of rotor string;
4. After installing the balance disk, measure the half string of rotor;
5. Compared with the total string quantity and half string quantity required on the general assembly drawing of the manufacturer, it shall basically meet the requirements of the drawing. Generally, the half string quantity is about half of the total string quantity;
6. Tighten all main bolts evenly, and pay attention to diagonal;
7. Suck a dial indicator on the shaft and rotate the shaft to mark the balance disc. The tolerance shall meet the requirements of the drawing and generally shall not exceed 0.06;
8. When installing the thrust bearing, pay attention to adjusting the clearance of the balance disc, and use the adjusting ring in front of the bearing to adjust the clearance of the balance disc to the requirements of the drawing.

Which barrows should I buy torags or guthans? Both are reasonably priced for me. In addition, since I'm looking for the RS gold barrows set, should i stop working towards a fighter torso? Also what should i do with my dragon platelegs and rune platebody?
If you're looking to purchase a barrows set, I'd suggest Veracs. The skirt and helm give the best defense for their specific positions (of the armours for the barrows) and the brassard is slightly weaker than Torag's, Guthan's and Dharok's plates. The brassard, however, Verac's provides a good prayer bonus (unlike other armours of the barrows) and is a great set special.
As I'm sure there's already Dragon Legs and you're aiming to build a fighter's torso, so what I'd recommend for your to cheap OSRS gold consider is keep those as your main armour, but keep Guthan's set to make use of its special attack as a healing mechanism.
Hello everyone. My name is Naomi, executive director of the Al Wooten Jr. Youth Center at 91st and Western. Named after my cousin, killed in a drive-by shooting in 1990, the Wooten Center is a nonprofit agency providing free afterschool and summer programs for more than 300 students in grades 3-12 in the South Los Angeles area. We closed our center in March and went fully online with tutoring and more for grades 3-12. See www.wootencenter.org.
Our successes and challenges reengaging kids in their schoolwork and our tutorial activities since our temporary closure has motivated me to want to do more to help as many students as we can get back on track as soon as possible. As a result, I am serving as co-chair of the CRSSLA Education Committee. The committee is currently working on a series of case management trainings to help equip as many people as possible in the art of reaching out to youth and families. See Events above to RSVP for the trainings and our biweekly Education Committee meetings. Hope to meet you soon.
