How to Use a Hydraulic Pump Safely and Correctly

A hydraulic pump is the power source that converts mechanical force into hydraulic pressure to operate hydraulic cylinders, tunkit, vetäjät, momenttiavaimet, and other hydraulic equipment. Proper operation ensures maximum performance, turvallisuutta, and longer service life.

Hydraulic Pump Operating Guide

1. Check the Hydraulic System Before Operation

Before using the pump, inspect all components carefully.

Tarkista:

• Hydraulic pump condition

• Hydraulic oil level

• Hose condition

• Couplers and fittings

• Painemittari

• Hydraulic cylinder or tool connections

Make sure:

• There are no oil leaks

• All connections are tight

• The working pressure rating of all components matches the pump pressure

Never use damaged hoses, leaking fittings, or worn hydraulic components.

2. Select the Correct Hydraulic Oil

Use the recommended hydraulic oil specified by the manufacturer.

Before operation:

• Check oil level in the reservoir

• Add hydraulic oil if required

• Avoid mixing different types of hydraulic oil

• Keep oil clean and free from contamination

Contaminated hydraulic oil can damage:

• Pump valves

• Tiivisteet

• Sylinterit

• Internal hydraulic components

3. Connect the Hydraulic Components

For a typical hydraulic cylinder system:

Connection order:

1. Connect hydraulic hose to the pump outlet

2. Connect the other end of the hose to the cylinder coupler

3. Asenna painemittari tarvittaessa

4. Varmista, että kaikki liittimet ovat täysin lukittuja

Make sure:

• Liittimet ovat täysin kiinni

• Pölysuojukset poistetaan ennen liittämistä

• Liitännät ovat puhtaat liasta ja roskista

4. Avaa hydraulijärjestelmä

Ennen paineistamista:

• Avaa vapautusventtiili kokonaan

• Varmista, että sylinterin mäntä on vedetty kokonaan sisään

• Varmista, että kuorma on asetettu oikein

Sähkö- tai ilmakäyttöisille pumpuille:

• Varmista, että virtalähde vastaa pumpun vaatimuksia

• Tarkista moottorin pyörimissuunta tarvittaessa

• Varmista, että hätäpysäytys toimii oikein

5. Käytä hydraulipumppua

Manuaalinen hydraulipumppu

Käsipumpuille:

1. Sulje vapautusventtiili

2. Liikuta pumpun kahvaa ylös ja alas

3. Hydraulipaine kasvaa

4. Tarkkaile painemittaria

5. Lopeta pumppaus, kun vaadittu paine tai asento on saavutettu

Sähköinen hydraulipumppu

Sähköpumpuille:

1. Kytke virtalähde

2. Käynnistä pumpun moottori

3. Käytä ohjausventtiiliä sylinterin pidentämiseen

4. Monitor pressure on the gauge

5. Stop operation when the required force is achieved

Ilmahydraulipumppu

For air-driven pumps:

1. Connect compressed air supply

2. Adjust air pressure according to specifications

3. Activate the control valve

4. Monitor hydraulic pressure

5. Stop when the operation is complete

6. Monitor Pressure During Operation

Always observe the pressure gauge.

Important:

• Never exceed the rated pressure

• Maximum operating pressure is commonly 700 baari (10,000 psi) for many industrial hydraulic systems

• Avoid sudden pressure increases

• Stop immediately if abnormal noise, tärinää, or leakage occurs

7. Releasing Hydraulic Pressure

After completing the operation:

1. Stop the pump

2. Slowly open the release valve

3. Allow hydraulic pressure to decrease gradually

4. Confirm the cylinder returns safely

5. Disconnect hoses after pressure reaches zero

Never disconnect hydraulic hoses while the system is pressurized.

8. Hydraulic Pump Maintenance

Regular maintenance improves reliability.

Daily Inspection

Tarkista:

• Öljyvuotoa

• Hose damage

• Coupler condition

• Oil level

• Pressure gauge accuracy

Regular Maintenance

Suorittaa:

• Hydraulic oil replacement

• Filter cleaning or replacement

• Seal inspection

• Hose replacement when worn
