AM BOTTOM EDGES OF THE DOOR AND FRP14E ARE MACHINED TO A MATCHING

TAPER WHICHALLOWS AUTOMATIC "SEALING OFF" OF THE CLEAR OPENING

IMEN DOORIS CLOSED.

2. A MECHANICAL INDICATOR2 DETAIL IlEft,, INDICATES THE POSITION OF THE

DOOR AT THEREMOTE MANUAL CONTROL STATION. THIS CONSISTS OF A

-TRANSMITTER MOUNTED AT THE DOOR, CONNECTED TO A FLEXIBLE CABLE

'WHICH IS RUN TO A RECEIVER INDICATOR AT THE REMOTE STATION.

B. HYDRAULIC EQUIPMENT - REFER TO DETAIL "B" PAGE 23

1. THE DOOR IS ACTUATED BY A HYDRAULIC CYLINDER�, PRESSURE BEING

SUPPLIED 13Y I.MOTOR DRIVEN PUMP AND� IN THE ABSENCE OF ELECTRIC

PO`iM OR IN CASE OF EMERGENCY., BY ROTARY HAND PUMPS.

2. TEE LOCAL HAND ?UMP IS LOCATED BESIDE THE DOOR AND HAS A SHAFT

IMICH PROTRUDES THROUGH THE BULKHEAD TO ALL014 OPERATION FROM

EITHER SIDE. HAND CRANKS MOUNTED ON THE SHAFT ALLOW THE OPERATOR

TO ROTATE THEPUNP. REVERSAL OF ROTATION REVERSES THE DIRECTION

OF TRAVEL OF THEDOOR.-

3. THE REMOTE HAND ?UNP, LOCATED AT THE REHOTEt MANUAL CONTROL STATION, IS UNI-DIRECTIONAL AND, IN ACCORDANCE WITH U.S.C.G. REGULATIONS, ALLOWS FOR CLOSING OF THE DOOR ONLY.

THE HYDRAULIC CONTROL VALVES ARE COMBINED IN A SANDWICH-TYPE OF

VALVE STACK, WHICH IS INCORPORATED IN THE MOTOR� PUMP AND VALVE

ASSEOLY.,

SECTION II (Continued)

DESCRIPTION & PRINCIPLES OF OPERATION (.Continued)

5. A 2 GALLON OIL EXPANSION TANK IS MOUNTED ABOVE AND ADJACENT To THE

REMOTE MANUAL PUMP. THIS MAKES UP THE DIFFERENCE IN DEMAND OF OIL

WHEN OPENING OR CLOSING THE DOOR DUE TO THE DIFFERENCE IN AREA OF

THE TWO SIDES OF THE PISTON.

C. ELECTRIC EQUIPMENT � REFER TO DRAWING PAGE 26

1. A REVERSING CONTROLLER STARTS AND STOPS THE MOTOR - PUMP UNIT,

ALLOWING 'ROTATION OF THE PUMP IN EITHER DIRECTION.

2. TBE CONTROLLER IS -ENERGIZED BY TWO LOCAL CONTROL SWITCHES MOUNTED

ONE ON EACH SIDE OF THE BULKHEAD IN CLOSE PROXIMITY TO THE DOOR.

3. A =OW -rICHT lk]�ICATING "OPEN" IS LOCATED AT THE ENGINE CONTROL

CENTER CONSOLE.

TEE DOOR MAY -BE OPENED OR CLOSED FROM THE LOCAL STATION.

5. THE LEADING EDGE OF THE DOOR CONTAINS A SAFETY STRIP SWITCH WHICH,

'UPO-N CONTACTVITH A-PERSON OR OBJECT CAUGHT IN THE OPENING, WILL

CLOSE. IT WILL RtEP REPEATING THIS CYCLE UNTIL OBSTRUCTION IS MOVED

FROM THE OPENING.

POWER OPERATED HYDRAULIC DOOR 7

SECTION III

INSTALLATION PROCEDURE - HYDRAULIC WELDED TYPE OF DOOR

A. DOOR AND FRAME ASSEMBLY

1. THE WALZ & KRENZER SLIDING WATERTIGHT DOOR AND FRAME IS A PRECISION

PIECE OF MACHINERY, EACH DOOR AND FRAME ASSEMBLY IS STRESS RELIEVED

PRIOR TO MACHINING AND, AFTER ASSEMBLY, IS HYDROSTATICALLY TESTED TO

FULL'DESIGN HEAD PRESSURE IN THE PRESENCE OF A U. S. COAST GUARD

INSPECTOR PRIOR TO LEAVING OUR WORKS.

2. THESE DOORS HAVE NO SEALING GASKETS, CONSEQUENTLY,, WHEN THE DOOR IS

ITEDGED INTO THE CLOSED POSITION THERE IS FULL METAL TO METAL CONTACT

BETWEEN THE BRASS FACE OF THE DOOR AND STEEL SEAT OF THE FRAME. THE

DOOR ASSEMBLY IS ESSENTIALLY THE EQUIVALENT OF A LARGE GATE VALVE.

ANY DISTORTION AFFECTS THE WATERTIGHT INTEGRITY. (SEE U.S.C.G. TEST

FOR TIGHTNESS, PAR. NO. 163-ool-6 (b) (5):

"The degree of contact between door and frame.shall be such as to exclude a .003" feeler gauge or its clear passage through and between the sealing surfaces at any point around the sealing perimeter".

3. THE FOLLOWING PRECAUTIONS SHOULD BE NOTED:

(a) NEVER COMPLETELY WELD FRAME INTO POSITION UNTIL MOST OF THE HEAVY

SHIP'S STRUCTURE IN THE VICINITY OF THE BULKHEAD, OVERHEAD DECKS

AND SUPERSTRUCTURE ARE WELDED IN PLACE. ADDITIONAL WELDING IN THE

AREA AND ADDITIONAL WEIGHT'OF SUPERSTRUCTURE COULD CAUSE DISTORTION

'OF THE DOOR FRAME MAKING IT NECESSARY TO CUT THE FRAME FREE AND

RDqELD IN ORDER TO COMPLY WITH THE CLEARANCES REQUIRED BY THE U.S.

COAST GUARD.

(b) IT IS WISE TO LEAVE THE DOOR FRAME TACKED IN PLACE UNTIL 140ST OF THE

WORK IN THE AREA IS COMPLETED. THESE TACKS CAN BE EASILY BROKEN

PERMITTING THE DOOR AND FRAME TO ALIGN ITSELF FREELY BEFORE FINAL

WELDING.

(a) WELD ONE BEAD UPWARDS APPROXIMATELY 12" LONG ON THE OPERATOR'S

LEFT FROM THE DOOR SIDE OF BULKHEAD,

(�b) CHANGE TO OPPOSITE SIDE OF BULKHEAD, WELDING ONE BEAD UPWARDS

APPROXIMATELY 12" FROM THE BOTTOM ON THEOPERATORkS LEFT, (.0 ON THE SAME SIDE OF THE BULKHEAD, WELD ONE BEAD UPWARDS APPROXIMATELY

12" LONG ON THE OPERATOR'S RIGHT.

(.d) CHANGE TO DOOR SIDE OF BULKHEAD, WELD ONE.BEAD APPROXIMATELY 12"

.LONG ON THE OPERATOR'S RIGHT.

-PROCEED, BEGINNING WITH OPERATION (a) ABOVE, UNTIL DOOR IS COMPLETELY

WELDED ON BOTH SIDES, BOTH FORWARD AND AFT SIDES OF BULKHEAD AND

-FOLLOW A SIMILAR PROCEDURE IN WELDING TOP-AND BOTTOM.

-THE ABOVE SHOULD NOT BE INTERPRETED AS A DEFINITE REQUIREMENT, BUT AS A

TROCEDURE THAT HAS BEEN TRIED AND FOUND TO WORK SATISFACTORILY. IN ANY CASE,

'EVERY EFFORT SHOULD BE MADE TO KEEP THE HEAT AT A MINIMUM AND DISTRIBUTED

AS EVENLY AS POSSIBLE.

AFTER COMPLETION OF WELDING, CHECK DOOR SEAT AND FRAME SEAT TO SEE THAT

'THEY ARE FREE FROM DAMAGE. A REASONABLE AMOUNT OF GREASE SHOULD BE

APPLIED TO THE SEAT OF THE FRAME AND THE SEAT AND WEDGING SURFACE OF

THE DOOR.

INSTALLATION PROCEDURE (Continued)

B. HYDRAULIC EQUIPMENT

1. THE DISTANCE BETWEEN THE DOOR PROPER AND THE REMOTE PUMP AND SUPPLY TANK

IS NOT TO BE IN EXCESS OF 6o,. WEVILL NOT ATTEMPT TO MAKE FITTING

RECOMMENDATIONS EXCEPTTHAT THEY SHOULD BE OF A CLASS SATISFACTORY FOR

THE PRESSURE SHOWN. ALL LINES ARE SUBJECT TO HIGH PRESSURE EXCEPT THE

3/4" LINE BETWEEN THE SUPPLY TANK AND THE VALVE BLOCK. THE TUBING SIZES

SPECIFIED ON DRAWING, PAGE 23, ALLOW FOR A REASONABLE NUMBER OF BENDS

AND FITTINGS AND IN NO CASE SHOULD A SMALLER SIZE BE USED.

2. IT IS MOST IMPORTANT THAT ALL HYDRAULIC LINES BE CLEANED AND FLUSHED

BEFORE CONNECTING TOANY OF THE PUMPS,, VALVES OR CYLINDERS. DUE TO THE

NATURE OF THE HYDRAULIC CIRCUIT IT MAY BE NECESSARY TO DISASSE1,1BLE ALL

COMPONENTS IN THE SYSTEM IF THE SYSTEM BECOMES CONTAMINATED. USE BENDING

TOOL TO MAINTAIN MAXIMUM AREA. TUBING SHOULD BE CAREFULLY AND PROPERLY

FITTED, MAKING SURE THAT NO BURRS, CHIPS OR OTHER FOREIGN MATTER ARE

ALLOWED IN THE SYSTEM. TUBING SHOULD BE INSTALLED AT A SLIGHT PITCH

WITH VENT VALVES PLACED AT THE HIGH POINT.

3. IN THE FOLLOWING PARAGRAPHS, ALL ITEMS IDENTIFIED BY REFER TO DETAIL

"C", PAGE 23. MAKE CONNECTIONS AS SHOWN ON DETAIL "B". WHEN INSTALLATION

IS COMPLETE, FILL TANK WITH A GOOD GRADE OF PETROLEUM BASE HYDRAULIC FLUID

MEETING THE MINIMUM QUALITIES OF MILITARY SPECIFICATION NO. MIL-L-17672B,

SYMBOL 2135 T-H OR THE FOLLOWING:

VISCOSITY SUS � 1000 225-325

OPEN VALVES #19 AND #20.

POWER OPERATED HYDRAULIC DOOR 10

INSTALLATION PROCEDURE (Continued)

4. IT IS ASSLrMED THAT DOOR IS IN AN OPEN POSITION. OPEN VENT ON MOUNTING

END OF CYLINDER, ROTATE CRANK IN CLOSING DIRECTION AT REMOTE STATION

UNTIL OIL FLOWS FREELY FROM VENT. CLOSE VENT AND CONTINUE TO ROTATE

CRANK UNTIL DOOR CLOSES.

5. REMOVE 1/411 SOCKET HEAD PIPE PLUG FROM'DRAIN LINE IN QUAD CHECK VALVE,

ITEM H7 PAGE 23, UNTIL OIL FLOWS. REPLACE PLUG. OPEN VENT AT ROD END

OF CYLINDER. ROTATE CRANK ON LOCAL PUMP IN OPENING DIRECTION UNTIL ALL

AIR IS EMITTED. CLOSE VENT�AND ROTATE CRANK UNTIL DOOR IS OPENED. IT

MAY BE NECESSARY TO VENT MOUNTING END OF CYLINDER AND ROTATE LOCAL PUMP

EMITTING AIR AND CLOSING DOOR: THEN REVERSE OPERATION UNTIL SYSTEM IS

FREE FROM AIR. IT IS IMPERATIVE THAT ALL AIR IS OUT OF THE SYSTEM TO

INSURE PROPER OPERATION.

6. IF THE DOOR DOES NOT CLOSE PROPERLY, FOREIGN MATTER WILL UNDOUBTEDLY

BE FOUND UNDER-ONE OF THE QUAD-CHECK VALVE BALLS OR THEY MPAY BE STICK-

ING DUE TO CONTAMINATION OF OIL, ALLOWING OIL TO ESCAPE FROM THE CLOSING

SIDE OF THE CIRCUIT. A SIMILAR CONDITION IN THE OPENING SIDE OF

THE LINE WOULD AFFECT THE OPENINVOF THE DOOR. REFER TO DRAWING PAGE

24, ITEMS #9 AND #12.

-THE CLOSING CIRCUIT IS A DUPLICATE OF THE OPENING CIRCUIT EXCEPT THAT,

FROM THE REMOTE STATION, THE DOOR MAY BE CLOSED ONLY. A SHUTTLE VALVE

IS USED TO CONTROL THE FLOW OF OIL, ITEM 10 PAGE 24. THIS VALVE IS

AUTOMATICALLY OPERATED BY A PILOT PRESSURE CREATED BY THE PUMPS AS

ROTATION IS CHANGED. THE CIRCUIT IS SO ARRANGED THAT A FEW SECONDS

ARE REQUIRED TO ALLOW THE SHUTTLE VALVE TO SHIFT FROM ONE POSITION TO

ANOTHER. THEREFORE, IT IS DESIRABLE TO DELAY REVERSING ROTATION OF

LOCAL PUMPS FOR A FEW SECONDS AS AN IMMEDIATE CHANGE OF ROTATION TENDS

TO INCREASE DELAY IN MOVEMENT OF DOOR RATHER THAN DECREASE IT.

,POWER OPERATED HYDRAULIC DOOR 11

INSTALLATION PROCEDURE (-Continued)

8. THE LOCAL PUMP, #5, DRAWING PAGE 24, IS A HIGH CAPACITY, LOW SPEED, GEAR

TYPE POSITIVE DISPLACEMENT, REVERSIBLE PUMP. IN THE EVENT THAT THE SHIP

STRUCTURE IS SUCH THAT IT IS NOT POSSIBLE OR PRACTICAL TO EXTEND THE CRANK

THROUGH THE BULKHEAD FOR OPERATION ON THE OPPOSITE SIDE, TWO PUMPS MAY BE

SUPPLIED IN LIEU OF ONE, BOTH OF WHICH WOULD HAVE SINGLE SHAFT EXTENSIONS

AND COULD BE LOCATED IN ANY CONVENIENT LOCAI�ION NEAR-THE DOOR APPROVED BY

THE U. S. COAST GUARD. WHERE TWO LOCAL PUMPS ARE USED, INCREASE TUBING

SIZE TO 3/4" O.D. BETWEEN VALVE BLOCK AND PUMPS. A HINGED TYPE HANDLE MAY

BE FURNISHED IN LIEU OF THE RIGID HANDLE IN THE EVENT THAT SPACE IN THE

PASSAGEWAY IS LIMITED. THIS DESIGN HAS ALSO BEEN APPROVED BY THE U.S.

COAST GUARD.

9. THE REMOTE PUMP, #6, DRAWING PAGE 24, IS A DUPLICATE IN CONSTRUCTION AND

CAPACITY OF PUMP #5, EXCEPT THAT IT IS NON-REVERSIBLE INASMUCH AS IT IS

ONLY NECESSARY TO CLOSE THE DOOR FROM THE REMOTE STATION. A SURGE TANK,

#1, DRAWING PAGE 24, 2 GALLON CAPACITY, IS PROVIDED TO BE INSTALLED NEAR

THE REMOTE PUMP TO ALLOW FOR A SLIGHT SURPLUS OF OIL AND ALSO THE

EXPANSION AND CONTRACTION RESULTING FROM THE UNEQUAL ENDS OF THE CYLINDER

DUE TO PISTON DISPLACEMENT. SHUT-OFF VALVE H-19 AND H-20, PAGE 23, ARE

RECOMMENDED SO THAT OIL IN THE TANK MAY BE SHUT OFF IN THE EVENT OF LEAKAGE

IN THE JOINTS OR IF REPAIRS MAY BE NECESSARY. SHUT-OFF VALVES ARE NOT

SUPPLIED BY WALZ & KRENZER AS STANDARD EQUIPMENT BUT MAY BE PROCURED

UPON REQUEST.

10. A SINGLE DOUBLE-ACTING CYLINDER, A, DRAWING PAGE 24, IS 2-3/4" BORE WITH

A STROKE SUITABLE FOR THE OPENING OF THE DOOR SHOWN. THIS CYLINDER IS

EQUIPPED WITH A NON-ADJUSTABLE PACKING GLAND AND WIPER WHICH PREVENTS

LEAKAGE AT EITHER THE OPERATING PRESSURE WHICH IS A MAXIMUM OF 800 P.S.I.

OR THE STATIC HEAD WHICH 14AY BE AS LOW AS 3 P.S.I. DEPENDING ON THE

POWER OPERATED HYDRAULIC DOOR 12

INSTALLATION PROCEDURE (Continued)

LOCATION OF REMOTE STATION. REMOVAL OF CYLINDER ROD NUT WILL ALLOW

'FOR OPENING AND CLOSING THE DOOR IN THE EVENT OF MECHANICAL FAILURE.

MOTOR PUMP, #H-9, DRAWING PAGE 23, IS AN INTERNAL AND EXTERNAL PUMP

DRIVEN BY A TORQUE TYPE MOTOR. VALVE ASSEMBLY, PUMP AND MOTOR ARE

MOUNTED ON A COMMON BASE, DETAIL "B" PAGE 23. HYDRAULIC CONNECTIONS

HAVE BEEN MADE AT THE FACTORY AND ENTIRE ARRANGEMENT HAS BEEN TESTED

AS A COMPLETE UNIT.

12. PRESSURE SWITCH, #14, DRA14ING PAGE 24, HAS BEEN SET AT APPROXIMATELY

750 P.S.I.

13. IMPORTANT NOTES:

(a) WHERE POSSIBLE WE SUGGEST THAT HYDRAULIC LINES TO THE CYLINDER

BE RUN UNDER THE DOOR TO MINIMIZE THE POSSIBILITY OF TRAPPING

A-TR. BLEED VALVES SHOULD BE INSTALLED WHERE HIGH POINTS

OCCUR IN THE PIPING.

(b) IT IS MOST IMPORTANT THAT ALL HYDRAULIC LINES BE CLEANED AND

FLUSHED BEFORE CONNECTING TO ANY OF THE PUMPS, VALVE

BLOCKS, CYLINDER, ETC.

(c) DO NOT REMOVE THE PLUGS FROM ANY OF THE COMPONENTS UNTIL

READY TO MAKE CONNECTIONS.

(d) DUE TO THE NATURE OF THE HYDRAULIC CIRCUIT, IF THE ABOVE PRO-

CEDURE IS NOT FOLLOWED IT MAY REQUIRE COMPLETE DISASSF14BLY OF

ALL COMPONENTS TO REMOVE ANY ENTRAINED FOREIGN PARTICLES.

(e) THE OIL IN THIS CIRCUIT DOES NOT HAVE UNI-DIRECTIONAL FLOW AND

FOR THIS REASON CANNOT BE FLUSHED AFTER COMPONENTS ARE CONNECTED.
