Frequently Asked Questions - ZXAC220V-2.2KW-D-15L Vevor

What hydraulic oil to use for the Vevor ZXAC220V-2.2KW-D-15L power unit?

Use an ISO VG46 anti-wear hydraulic oil (kinematic viscosity 22-46 mm²/s at 50°C). If the oil temperature exceeds 50°C, prefer ISO VG68. In cold environments, use ISO VG32. Always filter the oil when filling with a precision of at least 25 µm.

How to adjust the hydraulic system pressure?

The pressure is preset at the factory between 18 and 20 MPa. To adjust it, turn the relief valve knob. Caution: never exceed the system's rated pressure. The valve also serves as a safety limiter.

What is the maximum duty cycle of this hydraulic unit?

The system is designed for intermittent operation (S3): 30 seconds maximum run, followed by 270 seconds stop. Do not exceed 180 seconds continuously, otherwise risk of short circuit or motor damage.

How to lower the cylinder after raising?

To lower, press the handle of the manual relief valve. Release to stop the descent. You can adjust speed by turning the throttle knob: inward slows down, outward speeds up.

What to do if the unit does not raise or raises unsmoothly?

Check the oil level in the tank (add if necessary). Make sure to use an oil of appropriate viscosity (ISO VG46). Clean or replace the oil filter screen. Check the tightness of suction hoses and that the solenoid/manual valves are properly closed.

What is the oil tank capacity?

The tank has a capacity of 15 pints, approximately 7.1 liters. Fill to 3 to 5 cm below the top surface.

How to electrically connect the hydraulic unit?

The unit operates on 220-240 V AC (or 110 V depending on model). Follow local electrical codes. The motor must be grounded to prevent electric shock. If voltage is unstable, use a voltage regulator.

When should the hydraulic oil be changed?

After the first commissioning, change the oil after 3 months. Then, perform an oil change every 12 months or after approximately 1500 hours of operation.

The unit fails to maintain pressure: what to check?

If the cylinder does not hold the load, the check valve may be dirty or defective. Clean it or replace the seal. Also check that the manual relief valve is properly closed.

What accessories are supplied with the hydraulic unit?

The unit is delivered fully assembled with a portable remote control and a spare SAE#6 connector. Other fittings are available separately.

INSTRUCTIONS

The hydraulic power unit is formed by the variation of the hydraulic system. In order to make the hydraulic station small in size, light in weight, and aesthetically pleasing, while also having unique functions, the gear oil pump, various control valves, motors, and fuel tanks are closely connected together, forming the current hydraulic power unit.

CAUTION

• This vehicle hydraulic pump is an S3 working system, not for continuous operation. It operates for 30 seconds and then stops for 270 seconds. The maximum working time is 180 seconds, with an intermittent period of 360 seconds. Continuous working time that is too long will cause motor short circuit or damage.
• When the hydraulic power unit produced by our Company leaves the factory, the system pressure has been set. If changes are needed, users can adjust the system pressure themselves through a pressure regulator knob according to the actual situation, but it cannot

exceed the nominal pressure of the system.

• Check the connection of the motor and electromagnetic valve carefully, and it is strictly forbidden to make a virtual connection.
• During the first installation and debugging, pay attention to keeping the oil level inside the oil tank. After a working cycle, the oil tank should be filled, but it cannot be overfilled.
• The hydraulic oil must be filtered when the oil tank is filled, with filtering accuracy of no less than 25μm.
• The power unit cannot filter out impurities inside the hydraulic cylinder. Therefore, the inside of the hydraulic cylinder must be clean to prevent the failure of the valve. The tubing must also be clean.

SCHEMATIC DIAGRAM

WORKING PRINCIPLE AND WIRING METHOD

1. Please fill in hydraulic oil from the reservoir filler until it is 3 cm to 5 cm below the upper surface of the reservoir.
2. Rise of the lifter:

After the motor starts, the gear oil pump ② starts to work, and the hydraulic oil passes through the oil filter ① to the check valve ⑤ through the gear oil pump ②, and then enters the oil cylinder ⑨ to raise the lifter. When the motor stops, the gear oil pump ② stops working, and the lifter stops at the position being raised. In this case, the check valve ⑤ and the manual unloading valve ⑦ are used to maintain its pressure.

1. Drop of the lifter:

To drop the lifter, just press down the handle of the manual unloading valve ⑦ and release the handle to stop dropping. The dropping speed can be realized by adjusting the throttle valve ⑧. When rotating inwards, it slows down; when rotating outwards, it speeds up.

1. System pressure adjustment of power unit:

Generally, when the power unit leaves the factory, it has been adjusted to the normal using pressure by the manufacturer (18-20MPa). If the user needs to adjust the pressure, he or she can adjust through the relief valve ⑥. The relief valve ⑥ is not only used to adjust the pressure in the system, but also used as a safety pressure limiting element in the system. So users should try not to adjust the relief valve during use.

1. In order to protect the working life of the motor and gear oil pump, reduce the noise during starting, and make the power unit start under load, a cushion valve ④ is specially configured in the system.
2. Refer to the unit nameplate, the power unit of 220V (or 110V) voltage

is adopted, and a voltage regulator should be equipped, to ensure that the motor and related electrical components are not damaged due to unstable voltage.

1. The hydraulic oil should be changed 3 months after the first operation of the system, after that, the hydraulic oil should be changed every 12 months. Please use ISO46# hydraulic oil.

COMMON FAILURES AND TROUBLESHOOTING

1. Does not rise (advance) or rises (advances) unstably.

a. Oil level in the oil tank is too low; add oil to the specified level. b. The hydraulic power unit should use anti-wear hydraulic oil with a kinematic viscosity of 22-46 mm²/s (at 50°C). ISO VG46 is recommended when the oil temperature is below 50°C, while ISO VG68 is recommended when the oil temperature is above 50°C. The added oil should be filled through a filter with a filtration accuracy of 30 μm. The oil volume should be of the effective capacity of the oil tank. The oil temperature is usually between -10 and 80°C, and low-temperature hydraulic oil should be used for extremely cold areas, such as ISO VG32. These measures can effectively prolong the service life of the hydraulic system and hydraulic components and improve the stability and reliability of the hydraulic power unit.

c. Blocked oil filter screen; wash or replace the filter screen.

d. Unsealed or leaking oil suction pipe; check the leakage or unsealed place, and repair or replace the pipe.

e. Unclosed electromagnetic valve or hand valve; wash the electromagnetic valve and hand valve or replace the oil.

1. Does not drop or drops unstably.

a. Blocked electromagnetic valve or hand valve filter screen; clean the screen and electromagnetic valve. b. Blocked throttle valve; adjust the throttle valve.

1. Does not pressurize.

a. Unsealed check valve; wash the check valve or replace the oil seal.

oil.

SIMPLE COMMISSIONING DIAGRAM

MAINTENANCE

1. Actuators and pipelines should be kept clean to prevent the introduction of foreign material into the system.
2. The reservoir should be adequately filled with oil. Proper refilling is needed after certain working cycles. It may damage the oil pump and enclosure if the oil pump sucks air.
3. The hydraulic oil should be replaced after the first 100 hours of operation. Subsequently, it should be replaced annually or after approximately 1500 working hours.
4. The viscosity of the hydraulic oil should be 225.46 mm
5. High-viscosity hydraulic oil should be used in high-temperature work environments, while low-viscosity hydraulic oil should be used in low-temperature environments.
