tion, operation and service of Link-Belt. traveling water screens. The long life and economical operation built into the machine is dependent to a great extent on the core token during installation and subsequently to proper lu-brication and service.

Procedures outlined here for erecting traveling water screens represent a simple, effective and accepted method. Other procedures may work equally as well and variations may prove necessary and advisable depending on local conditions and surroundings.

Link-Belt traveling water screens, because of their size, bulkiness and individual contract variations must be shipped as smaller assemblies. Sub-assemblies and indi-vidual parts furinished for your particular screen are com-pletely specified on the installation drawing provided.

Make sure instructions applying to your screen are fol-lowed.

The model 45A screen is the larger of the two screens, having 24' pitch trays. The model 46A has 18' pitch trays.

After installing screen, file this manual for reference.

All correspondence pertaining to this screen should be addressed to Link-Belt Company, giving model and con-tract number stamped on screen nameplate.

PREPARATION OF SITE Before installing screen, check size of well with founda-tion drawings. Make sure guideways and anchor bolts are properly set. Remove all debris from bottom of well and any obstructions in guideway slots that might inter-fere with insertion of the screen frame.

Assembly of boot section Boot sections are normally shipped assembled as shown in Figure 5763. Field check all dimensions shown to make sure alignment was not disturbed in shipment. Correct variations from dimensions given before placing boot sec-lion in pit.

If boot section is received knocked down, assemble it as follows:

1.

Bolt boot castings to side plates.

2. Bolt side plates loosely to cross beam and boot plate to boot castings. Use washer shims, if required, to maintain a constant dimension between top surface of boot casting and boot plate.

3.. Side plates must be square with the boot plate, in line with and parallel to each other. Adjust distance be-tween boot castings to dimension shown and shim cross beam if necessary to maintain dimerticn shown between the side plate flanges.

4.

Assemble sprockets and collar loosely on shaft and put this assembly and bearing halves in place in boot.

5.

Hold bearings loosely in place with U-bolts and align shaft with boot plate and track casting to radii given, by using shims under the bearings. Shaft must turn freely in bearings.

6. Slide sprockets into position so center-to-center dis-tance is correct and sprockets are located symmetri-cally about center line of boot; lock in place.

7. Adjust bearings along the shaft, if necessary, to pro-vide )4' clearance between sprocket hubs and bear-ings. Tighten U-bolt nuts and jam nuts.

1.

Fill speed reducers with oil. All Link-Belt speed reducers are shipped without oil and must be filled to correct level before operating. Follow instructions attached to dr;ve and on nameplate.

2.

Check oil level in fluid coupling. The fluid coupling is located between speed reducer and motor. The cou-pling is lubricated at the factory but check oil level to be sure that oil has not been lost in shipment. Note that coupling must not be filled to the top.

3.

Lubricate all bearings on screen proper, as shown in Figure 5778, page I 1.

Check motor and adjust controls Single-speed screen Operate screen and check for proper direction of travel.

See drive installation drawing, Figure 5772, page 7.

Dual-speed screen Dual-speed screens are normally furnished with star con-nected dual voltage motors and suitable controls. The two sets of windings available in this type motor are utilized, together with an auxiliary gear reduction in drive to pro-duce two screen speeds. The fluid coupling provides the some protection from machinery overloads in both cases.

When operating on parallel connected windings, by setting starter control level at high speed position, the motor develops full horsepower to operate screen at about 10 FPM.

When starter control lever is set at low speed, it oper-ates the motor on series connected windings to develop about one-quarter full motor torque. The motor runs in a direction opposite to high speed rotation and in so doing automatically engages an auxiliary 4 to 1 gear reduction in the speed reducer to operate screen at about 2 t/ FPM.

The speed reducer is designed so reversal of motor rota-tion does not reverse direction of screen travel.

Screen speed may be changed from high to low or from low to high at any time by reversing the position of the control lever on the starter.

Wire drive control in accordance with wiring diagram to assure proper overload protectry rovided by the PAGE 2-r F P9863 10

LUBRICATION drive. To make sure control is properly wired, check the following:

1. High and low speed push buttons, or other pilot sig-nols, must close their corresponding high and low speed contactors in the control.

2. High speed contactors must be connected to the low voltage connections in motor and the low speed contacts to the high voltage connections in motor.

3. Check drive operation by placing control level in high speed position and start motor. See drive installation draw-ing, Figure 5772, page 7, for proper direction of screen travel. Speed reducer output shaft should revolve at the high speed stamped on drive nameplate.

4. If reducer output shaft does not operate at high speed, reverse motor rotation by interchanging any two of the three power supply leads to the control. Do not reverse motor by interchanging leads at any other point.

5. Reducer output shaft should now rotate at high speed with the control lever in high speed position and at low speed with control lever in low speed position.

6. If work is performed on power supply, controls, or motor, repeat above checks before placing unit back in operation.

Operate screen Operate screen with power for a period of one hour or more to check all drives and bearings for excess heating due to tightness or misalignment.

If screen is operating in a dry well, lubricate foot shaft bearings with oil.

Check spray nozzles Check spray nozzle orifices and make sure they are open and correctly positioned.

OPERATION Single-speed screen Link-Belt traveling water screens are designed to handle the capacity specified in the contract when screen cloth is clean. The normal head loss between the front and back of the screen will be quite small when trays are clean. An operating schedule should be worked out de.

pending upon prevailing conditions, so trays will be cleaned often enough to prevent difference in head ex-ceeding 6 to 8 inches.

If screen stalls due to excessive head, lower head by removing obstructing material, stopping the main pumps momentarily if necessary before again operating.

If screen stalls due to an obstruction in well, correct cause of stalling before resuming operation.

The life of moving parts will be lengthened if screen is operated intermittently. Do not operate continuously unless absolutely necessary.

Always operate water sprays before starting screen.

Dual-speed screen The preceding instructions regarding operation of the single-speed screen also apply to the two-speed screen.

The two-speed drives on these screens provide a high speed of approximately 10 FPM for quick cleaning cycles of short duration. A low speed of about 2 1/1 FPM is pro-vided for continuous operation during periods when vol-ume of incoming trash to be removed from the water is heavy, or during periods when operator is not present.

This slow speed is used to protect against sudden influx of trash which would block screen unduly when station-ary. Under exceptional conditions it may be necessary to operate screens continuously at 10 FPM although this is not recommended except as an emergency measure.

Lubrication points are shown in drawing above.

Change oil in speed reducer, regrease motor and replen-ish fluid coupling oil as specified in instructions originally furnished with these units.

Lubricate drive chain once a week with a water re-pellent grease applied with a paddle or brush.

Lubricate head shaft and chain tightener bearings daily with water repellent grease; three grease points.

Lubricate takeup nuts before turning each time head shaft is adjusted. Keep takeup screws coated with some grease used on drive chain; two grease points.

Lubricate screen chain joints with water repellent grease intermittently, depending upon operation. Lubrication once every 200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> of actual running time is recommended.

If chains are loose, undue wear will occur on boot tracks and chain rollers; if extremely loose, damage will result from accumulation of excess slack at point where down-stream chains join foot sprocket.

When tightening chains, keep head shaft level at all times. Turn adjusting nuts, simultaneously, and each ex-actly the same number of turns. The nuts have 6 threads per inch. Tighten chains until rollers are tightened into the pockets of the foot wheels, then back off each capstan nut 1 1/2 turns to obtain running freedom.

Screen trays An occasional check-up, to make sure that the bolts which connect the screen trays to the chains ore tight, may pre-vent a serious breakdown.

Cleaning spray pipes Check washing action of the sprays every few days to make sure dirt or slime has not clogged the orifices in the spray pipes.

Remove and clean the spray pipes if the orifices be-come clogged.

Replacement of head sprocket parts DIFFERENTIAL HEAD CONTROL Operation The differential head control is an optional accessory used to operate the traveling water screen automatically or actuate an alarm when the differential head exceeds a predetermined setting. It is a factory assembled, floor mounted self contained unit requiring only external con-nection of air and power lines at installation site.

An air purge system is utilized to measure the differ-ential head across the screen and provide means for actu-ating the control. In operation, air is fed through open end tubes immersed in the water on each side of the screen and the air flow adjusted by means of needle valves and rotameters so the flow is the some in each tube.

When a differential in head occurs, the pressure in the downstream tube will drop. This pressure difference is used to actuate either a pneumatic force-balance trans-mitter or a mercury manometer, depending on which type is furnished. These instruments in turn operate the neces-sary electrical controls to start spray water p-imns and screen motor in an automatic system, or an alarm in a manual system, when setting of instrument is exceeded.

With an alarm control system the spray pipe valve and screen drive motor must be operated manually after the alarm functions and screen must be operated until the head returns to normal.

When an automatic control system is used, a starter, three position selector switch and a reset timer are sup-plied. When selector switch is in automatic position and the differential head is exceeded the solenoid valve on the spray pipes and the screen drive motor are auto-matically operated and timer reset. When the head returns to normal the timer automatically continues operation of screen until all trays are cleaned.

When selector switch is in manual position the auto-matic controls are by-passed and screens must be operated manually. This control setting permits operation of screen for routine testing regardless of whether a difference in head exists.

After use in manual position, return selector switch to autonmatic so the instrument can control the operation of screen based on differential head.

Installation

1. Bolt control panel to floor as close to screen as possi-ble, making sure that there is access room at rear of panel. Panel should be well lighted, clean and free from excessive vibration and temperature extremes.

If a mercury manometer is used be sure it is level.

2.

Install upstream and downstream purge lines making sure lower ends of copper tubes are at same eleva-tion, and to a depth that will assure the ends being submerged at least 12 inches under minimum water level when operating. Clamps are provided for secur-ing tubes to wall. Be sure tubes clear path of trays.

3.

Connect purge lines A and C to proper high (up-stream) and low (downstream) fittings on control panel. All joints must be air tight.

4. If mercury manometer is used, fill manometer body with mercury. Consult manufacturer's instruction book furnished for instructions.

5.

Connect air supply to fitting B on control panel. Be sure aJI valves on control panel are closed before opening main air supply valve.

6.

Connect control lines M from starter and timer to proper terminals on control panel as shown on wiring diaaram orovidod with e&pent.

Final adjustment Mercury manometer controls

1. Adjust regulator E until gouge F indicates a pressure in pounds per square inch of 1.1 times maximum wa-ter depth in feet. Thus, for a 50 foot maximum water depth the gauge reading would be 50 X 1.1 = 55 psi.

2. Adjust valves at rotameters G so float is approx. cen-tered on scale. Both rotameters should indicate same flow although the exact rate is unimportant.

3. Set timer for a period of time long enough to permit screen to complete one cycle.

4. Open equalizing valve K and close valves J and L, meter N should register zero. Open valves J and L, meter N should still register zero if water level in front and in back of screen is the same. If meter N does not register zero when valves K, J and L are all opened, consult meter manufacturer's manual fur-nished, for further instructions.

5. Close valve K. Always open valve K before opening or closing valves J and L and close valve K after op-erating J and L. If valves are not operated in proper sequence, meter can be damaged by over travel.
