Description

Orange industrial pressure vessel with coiled hose and attached control panel (no visible text or symbols)

The product is a tool widely used across various industries, including automobile manufacturing, engineering technology, aerospace, and petroleum. Its primary function is to move hydraulic fluid to generate hydraulic power.

The pump operates by converting low air pressure into high-pressure hydraulic oil pressure. This is achieved by utilizing the low air pressure at the piston end with a large area to generate high hydraulic pressure at the piston end with a smaller area.

The user is liable for any damage resulting from unintended use of the device.

Installation

1. Air supply

The pump requires an air pressure of 0.3 to 1 MPa for operation. When the air supply is 0.67 m^3/min and the air pressure ranges from 0.65 MPa to 1 MPa, maximum oil supply and pressure are achieved. To ensure clean, lubricated air and extend the pump's lifespan, install an oil-water separator at the air intake.

The pump's intake end features a 1/4 NPT sealed pipe thread for connection to the air supply port. Wrap good-quality thread sealing tape around the pipe fitting, leaving the first thread turn free to prevent debris from entering the system, and tighten securely.

2. Hydraulic connections

The oil outlet has a 3/8 NPT sealed pipe threaded port. Use high-quality thread sealing tape on the pipe joint, leaving the first thread turn free to avoid debris in the system, then tighten it. The outlet oil pipe should be at least a 70 MPa-grade high-pressure pipe; failure to do so may result in pipe bursts or breakdowns, posing a serious risk of personal injury.

3. Vent valve (fuel filler)

Before using the pump, loosen the vent valve by 1 to 2 turns to prevent cavitation and damage to the pump. Close the vent valve when transporting the pump after use. The vent valve can also serve as an oil filler port; remove the entire vent valve from the pump cover to add hydraulic oil.

Operation

1. Checking the fluid level

Check the fluid level in the pump and follow the refuelling instructions in the section if refuelling is necessary.

2. The pedal operation

Oil supply: To start oil supply, set the reversing handle to the port end that will be supplied. Press the pedal to initiate oil flow to the system.

Suspend oil supply: When the pedal is in the neutral position (not pressed and not in the drain position), the pump stops running and holds the pressure.

Oil return: Rotate the reversing handle to the opposite oil port end. Press the pedal to allow the hydraulic system to return oil. To pause the return process, simply release the pedal, which will stop the return and maintain the instantaneous pressure at that moment.

3. Pump exhaust

Ensure the vent valve is open; if not, loosen it by 1 to 2 turns. Set the reversing lever to the neutral position, press the supply pedal for 3 to 5 seconds to expel any air trapped in the system, and the pump will then operate normally.

Cleaning and maintenance

1. Oil change

Hydraulic oil should be replaced every 350 hours of use. In environments with high levels of dirt, the oil change cycle should be shortened accordingly.

To change the oil, remove the case cover from the oil tank. Drain the old hydraulic oil, which may have deteriorated or become contaminated. Clean the pump body and oil tank by placing them in a cleaning

container and using clean diesel or kerosene. After drying with compressed air, refill the oil tank with clean 32# hydraulic oil and reassemble the components.

2. Air removal

Air may remain in the pump after an oil change, or air bubbles may form during transport. This can cause the air motor to run without generating hydraulic pressure. To remove the air, follow these steps:

• Connect compressed air.
• Set the reversing handle to the middle position.
• Press the pedal for 3-5 seconds to engage the air motor for 5-10 seconds.
• Check the oil port using the 4.2 oil supply instructions to see if oil leaks from the outlet. If the oil is released, the air in the pump has been expelled. If no oil is visible, repeat the process until oil emerges from the outlet.

Disposing of used devices

Do not dispose of this device in municipal waste systems. Hand it over to an electric and electrical device recycling and collection point. Check the symbol on the product, instruction manual, and packaging. The plastics used to construct the device can be recycled following their markings. By choosing to recycle you are making a significant contribution to the protection of our environment.

Troubleshooting

Problem	Possible	cause
1. The air motor does not work or stops working during operation.	Long time not used, condensate in compressed air rusting air motor parts lead to:1. Round-trip valve gets stuck due to oil or water rust.	1. Disassemble the air motor, clean the round-trip valve part and add grease. Alternatively, you can add a few drops of lubricating oil at the intake joint and then add some lubricating grease. Use compressed air to introduce it into the air motor, but this is only suitable for temporary use.
	2. Lubricating grease is diluted by condensate and then taken away by the air, piston ring and round-trip valve seals are badly worn, air leakage from the air motor.	2. Replace the piston ring and round-trip valve seal.
	3. The plunger reset spring and cylinder head top spring are broken.	3. Replace the spring.
2. The pump can produce pressure but the pressure holding is not good.	1. Damaged reversing valve spool seal.	1. Replace the sealing ring.
	2. Expired or unclean oil causes the reversing valve to wear and seal poorly.	2. Change the oil, clean the system components and replace the reversing valve part.
3. The pump can't reach the maximum pressure value.	1. The air motor is not working properly.	1. Check whether the intake switch and piston ring are not well sealed and leaky.
	2. After the impurities enter the safety valve, the seal is not good,	2. Check the safety valve, clean the pump head.
	resulting in oil leakage.
	3. Same with the second cause of failure.	3. Same with the second elimination method.
