Overview

• Introduction
• Technical Product Data

Atlas Copco Air Driven Pump Unit

Atlas Copco air driven pump units operate on the simple but efficient principle of power magnification through the use of differential areas. A relatively large air-operated piston drives the smaller piston, which provides fluid flow at high pressures. All Atlas Copco air driven pump units are fitted into an easily transportable, tubular steel frame.

The pump units are available, fitted with a large choice of pressure gauges and are supplied complete with an air pressure regulator which can be set to stall the pump unit when it reaches the pressure required for each particular tensioning application.

Precautions

Prior to connecting the hydraulic pump to any equipment, the user is to ensure that :

• The working pressure of the hydraulic pump and the equipment to be operated are compatible. i.e. maximum working pressure of the hydraulic tensioning tools, hydraulic connections & hydraulic hoses.

• The reservoir pump capacity is adequate to operate the equipment throughout its range.

The hydraulic oil specification used within the pump and the equipment are compatible.

Introduction

The operating and maintenance procedures listed within this manual should be adhered to and will enable the operator to obtain maximum efficiency and reliability from the equipment.

• Pump Preparation
• Safety ON/OFF Valve

Pre-Pressurization Checks

It is strongly recommended that the pump is checked for any leaks prior to any tensioning operations.

Setting Hydraulic Pump Stall Pressure

The pressure relief valve (See also Hydraulic Pump Assembly for part 3) is factory set by Atlas Copco not to exceed 1650 bar. If the air pressure is increased by the operator by accident, the pressure relief valve will blow or vent preventing excessive hydraulic pressure from being created.

The hydraulic pump in this unit has a hydraulic to pneumatic ratio of 330:1, hence for a maximum working pressure of 1500 bar, the required pneumatic air pressure is (1500 / 330) = 4.545 bar.

Setting Pneumatic / Air Pressure to Create Hydraulic Pressure

Before and After Connecting Air Supply

It is strongly recommended that the pump is regulated in order to stall at the required tensioning pressure. This process is achieved by the adjustment of the air regulator valve, See also Hydraulic Pump Assembly for component 7.

Before connecting an air supply, it is important to check the following.

• The pressure release valve is fully open (rotate Anti-Clockwise).

• The Dead-mans handle (See also Hydraulic Pump Assembly; part 12 ) is in the normally closed position i.e. in the highest position. To activate the valve, the dead-mans handles is de-pressed down, opening the air circuit.

• The oil reservoir has sufficient oil (Grade ISO 10, 32, 68).

• Check that the cap seal plug has been removed.

  

The oil tank on this pump unit is fitted with a cap seal plug to prevent oil spillage during transit. Remove the M6 cap screw and seal from tank cap prior to use.

Air Line Connection Process

Connect the air hose to the air inlet connector. Give the hose a sharp tug afterwards to ensure a solid connection.

Pump Preparation

Safety ON/OFF Valve

The pump unit is fitted with a safety ON/OFF valve. The spring loaded valve defaults to OFF when the valve handle is untouched. Holding the valve handle in the down position turns the pump ON. Releasing the handle turns the pump OFF.

Ergonomic Guidelines

Consider your workstation as you read through this list of general ergonomic guidelines to identify areas for improvement in posture, component placement, or work environment.

• Take frequent breaks and change work positions frequently.

• Adapt the workstation area to your needs and the work task.

  • Adjust for a convenient reach range by determining where parts and tools need to be located to avoid static load.

  • Use workstation equipment such as tables and chairs appropriate for the work task.

• Avoid work positions above shoulder level or with static holding during assembly operations.

  • When working above shoulder level, reduce the load on the static muscles by lowering the weight of the tool, using for example torque arms, hose reels or weight balancers. You can also reduce the load on the static muscles by holding the tool close to the body.

  • Take frequent breaks.

  • Avoid extreme arm or wrist postures, particularly during operations requiring a degree of force.

• Adjust for a convenient field of vision that requires minimal eye and head movements.

• Use appropriate lighting for the work task.

• Select the appropriate tool for the work task.

• In noisy environments, use ear protection equipment.

• Use high-quality inserted tools and consumables to minimize exposure to excessive levels of vibration.

Shut down procedure

Adjustment of Pressure Relief Valve

The pressure relief valve is factory set to vent air if a too high air pressure is set, thus preventing the pump from generating more hydraulic pressure. Adjustment is not necessary.

Do not adjust the pressure relief valve. A plastic cover has been placed over the valve to prevent any adjustment.

If the pressure relief valve has been triggered by excessive compressed pneumatic air pressure, reduce the air pressure by rotating the adjustment cap on the filter regulator in an anticlockwise direction. This will allow the spring and ball bearing assembly in the pressure relief valve to reset. When reset, increase air pressure to 5 bar. Any questions, please contact Atlas Copco.

Service Recommendations

Preventive maintenance is recommended at regular intervals. See the detailed information on preventive maintenance. If the product is not working properly, take it out of service and inspect it.

If no detailed information about preventive maintenance is included, follow these general guidelines:

• Clean appropriate parts accurately

• Replace any defective or worn parts

Lubrication Instructions

• Hydraulic Fluid

Hydraulic Fluid

The performance of hydraulic equipment is heavily dependent on the quality and characteristics of the hydraulic fluid selected for use. The choice of the specification and viscosity of the hydraulic fluid should be based of the conditions of use, taking into account several factors as follows:

• The range of environmental temperature.

• The range of oil viscosity defined for the equipment.

• The application (range of pressures, sources of contamination of the hydraulic fluid, the type of pump, etc.)

• The ease of getting a proper replacement or equivalent hydraulic fluid.

  Example: ISO Grade 15, 32 and 68.

  For changing or refilling the oil, it is recommended to use the same oil as supplied with the pump.

Troubleshooting

• Troubleshooting

Troubleshooting

If for any reason the pump does not run properly, look for one of the following causes:

• If the pump appears to be short stroking and running too fast without pumping properly, it usually indicates that the pilot valve assembly is not working as it should. Refer to instructions for the he hydraulic piston and repairing of the pilot valve assembly.

• Loss of pressure may be caused by one of two reasons; the hydraulic check valve have developed a leak or the hydraulic fluid is bleeding past the packing in the hydraulic cylinder. Replace the packing in the hydraulic cylinder or repair/replace the hydraulic check valve.

• Should the pump run erratically and in a jerky manner after a period of time, it is usually an indication of seizing in the hydraulic piston and cylinder assembly. Refer to instructions on how to disassemble the air motor and to replace the packing in the hydraulic cylinder. If the hydraulic piston and cylinder have not been damaged, a thorough cleaning will normally put the pump back into operation mode again.

• To ensure hydraulic fluid flow is optimized, ensure sufficient air volume is supplied to the pump. Hooking the pump up to a smaller pipe size than the “AIR IN” port on the pump will not allow it to run at its full rated capacity. Long runs of relatively small pipe supplying air to the pump will have the same effect.

• If an excessive amount of oil or water is pouring through the pump air exhaust, check for and correct;

  • Lubricating unit in the air supply is delivering too much oil. Adjust to about one drop of oil for every 20 strokes of the pump.

  • The hydraulic fluid being pumped (oil or water) may be leaking past the packing in the hydraulic cylinder into the air motor. Replace the packing in the hydraulic cylinder.
