1721-m4 Spec. Hydraulic Power Pump

Introduction

The1721 Spec. No. 60 pump is a high pressure hydraulic power pump of extremely durable construction, simple to operate and capable of delivering 10,000 psi.

This power pump has a built-in high volume / low pressure pumping feature which gives fast approach ram action and automatic changeover to low volume / high pressure when pressure exceeds 200 psi. The pumping unit consists of a one-piston radial-type capable of delivering 30 cubic inches at 10,000 psi. The pump also contains a relief valve which permits the motor to be shut off and restarted with load held at any desired pressure up to 10,000 psi. This pump has been pre-set at the factory for the desired pressure specifications to suit the compression machine model purchased.

Before attempting to adjust any valves (#1, 2, or 53), please consult the factory first.

SAFETY ALERT SYMBOL

This power pump is equipped with an externally mounted control valve which can be adjusted to vary the rate of loading over a wide range to meet the specifications for different specimens. For repetitious testing, the rate of loading can be pre-set exactly according to specification. A rapid traverse feature is included so that specimens can be preloaded as rapidly as desired. The control valve has a flow adjustment from 3 cubic inches per minute to 500 cubic inches per minute and can be easily adjusted by turning the micrometer adjusting knob located on top of the valve. Refer to Bulletin IM-711-B attached for further operating instructions and parts on the flow control valve and mounting plate.

Immediate hazards which, if not avoided, WILL result in severe personal injury or death.

IMPORTANT SAFETY INSTRUCTIONS

• Do not connect the pump to any system or system component other than those supplied by Greenlee and rated at less than 10,000 psi (68,950 kPa).

• Do not alter the internal high-pressure relief valve setting.

•

Do not use this pump in a hazardous environment. Hazards include open flame and flammable liquids or gases.

Failure to observe these warnings will result in severe injury or death.

Electric shock hazard:

• Do not expose power tools to rain.

• Do not immerse the pendant switch in water or other liquid.

Skin Injection Hazard: High pressure oil easily punctures

skin causing serious injury, gangrene or death. If injured seek medical help immediately to remove oil.

Do not use fingers or hands to check for leaks.

Depressurize hydraulic system before disconnecting the hose.

•I

nspect pump, hoses, couplers and fittings for wear or damage. Replace worn, damaged or missing components with Greenlee replacement parts.

• Do not twist, kink, curl, paint or cut the hydraulic hoses.

• Wear eye protection when operating this equipment.

• Disconnect the pump from the power supply, rotate the release valve lever to AUTO RELEASE and disconnect the hose from the ram and the pump before performing any service.

Failure to observe these warnings could result in severe injury or death.

• The pump is heavy, weighing up to 75 lbs. Follow NIOSH work practices for manual lifting. If in doubt, get help.

• Unplug pump when not in use and when changing accessories.

• Do not use the hose to pull, lift, or carry the equipment.

• Always work in an area providing good footing and support.

• Keep work area well-lit, free of clutter, and dry.

Failure to observe these precautions could result in injury or property damage.

Power

The power unit is equipped with a General Electric one HP, 1725 rpm, 115/230 volt, single-phase, 60-cycle, totally enclosed, fan-cooled, 15 min. 55˚C rise motor and rotates in a clockwise direction. This is standard equipment unless otherwise ordered.

For your protection, ground unit before using. The electric motor is equpped with an approved 3-conductor cord and 3-blade grounding-type attachment plug to be used with the proper grounding-type receptacle, in accordance with the National Electrical Code. The green-colored conductor in the cord is the grounding wire, which is attached to the metal frame of the unit inside the housing and to the longest blade of the attachment plug cap. A special grounding adapter is supplied (except in Canada or for use above 150 volts) to permit using two-wire receptacles until the correct receptacle is installed. The green grounding wire extending from the side of the adapter must be connected to a permanent ground such as a properly grounded outlet box, conduit or water pipe, before plugging in the unit. (If extensions are used, they should have sufficient rated capacity and a properly connected grounding circuit.)

Operating Instructions

This pump is designed to operate at 10,000 psi intermittently. For continuous service, as production work, the pressure should not exceed 6,000 psi. (This limitation is for motor protection only.)

Before operating pump, check the following to assure proper service:

1. Check for proper power connections and for tightness of hose connections before starting pump.

2. Check hydraulic oil with dipstick (54). Oil should be within 1/2" of reservoir top.

3. Start motor and allow pump to idle a few minutes. This will allow the hydraulic oil to work into the moving parts and give prime to pump.

Servicing Instructions

Filling Oil Reservoir. The oil reservoir must be kept

filled with a good grade of light hydraulic oil.

Never use synthetic fluids or fluids with poor lubricating qualities, i.e., brake fluids, etc., as permanent injury to the pump will result.

Eight quarts are required of which 6-1/4 quarts are usable. A minimum of 1-3/4 quarts must be at the bottom of the reservoir at all times during operation. Be sure that your complete operation does not require more than the usable amount of oil.

To refill or add oil to the reservoir, proceed as follows:

1. Remove vent unit from top of reservoir.

2. Add oil to within 1/2" of top of reservoir when ram is retracted.

3. Install vent unit securely in place.

Flushing System. As long as these pumps are used as outlined in the operating instructions, long, trouble-free performance can be expected. To maintain this performance, it is absolutely essential that dirt or other foreign matter be kept out of the system as this is the most common cause of hydraulic system failure. Therefore, when opening up the pump for any reason, such as making pipe connections, adjusting pressure or any repair, be sure to exercise extreme care in cleanliness and to use clean tools and cloths. If, at any time, dirt is suspected to have found its way into the system, the entire oil system should be flushed as follows:

1. Drain oil from reservoir.

2. Fill reservoir with any recommended flushing oil or clean kerosene and operate pump. Work the control handle back and forth several times during flushing to wash all foreign particles from the control valve unit.

Note: Do not operate pump for a very long time as

system is not designed to operate with flushing oil or kerosene.

3. Drain flushing oil or kerosene from reservoir and refill with new oil.

Check to see that vent unit is not clogged before attempting to operate pump.

Draining Oil Reservoir. Unscrew and remove 3/8 inch pipe plug (68) from side of pump base. Turn pump on its side to drain all oil from reservoir. Be sure to replace plug before refilling reservoir with oil.

Minor Hydraulic Trouble Chart

The hydraulic unit should be observed constantly for out-of-the-ordinary performance and unusual noises. If any of these are present, shut off pump and take corrective steps immediately to avoid possible expensive repairs later on. In most cases, a minor repair will solve the problem but it is suggested that, if trouble continues,

Pump motor will not start. Power cord not sufficiently connected. Check for tight connections.

Power cord cut. Replace. Defective motor or switch. Replace or repair. Fuse in wall box blown. Replace fuse.

Will not pump oil. Not primed. Run pump for a few minutes, tipping

Sticking plunger. Replace #8 & 9.

the unit should be returned to the factory or to a qualified service center for the proper repair. Under no conditions allow unqualified personnel to attempt to repair the pump, particularly the pump block unit, as serious, irreparable damage may result.

POSSIBLE REMEDYPROBLEM PROBABLE CAUSE

Air in system. Run pump to work out air. Loose drive shaft adapter. Tighten set screw #70. Defective motor. Replace.

Necessary to add oil often. Oil leaks. Check for broken lines, loose fittings,

or connections.

If the above corrective measures fail to make the pump function, it is recommended that you send the pump back to the factory or to a qualified service center.
