1.0 IMPORTANT RECEIVING INSTRUCTIONS
Carefully inspect all components for shipping damage upon receipt. Damage caused during shipping is not covered under warranty. If any damage is identified, immediately notify the carrier. The carrier is responsible for covering all costs of repair and replacement resulting from shipping damage.
2.0 SAFETY
2.1 General Hydraulic Safety Precautions
Before operating hydraulic systems, thoroughly read and understand all instructions, warnings, and safety precautions. This helps to avoid personal injury or property damage. The manufacturer is not liable for damage or injury resulting from unsafe use, feil vedlikehold, or incorrect operation. If unsure about safety measures or system operation, contact the manufacturer for assistance or attend a free hydraulic safety course.
Failure to follow the below precautions may result in equipment damage or personal injury:
- 2.1.1 Wear appropriate personal protective equipment (f.eks., gloves, safety goggles, boots) when operating hydraulic systems.
- 2.1.2 Do not set the pump’s relief valve higher than its maximum rated pressure. This can cause equipment failure or personal injury.
- 2.1.3 Ensure the system's operating pressure does not exceed the pressure rating of its lowest-rated component. Overpressure may reduce pump life.
- 2.1.4 Avoid sharp bends or kinks in hydraulic hoses, as these can cause severe back pressure and hose failure.
- 2.1.5 Protect hoses from impacts. Sharp impacts can damage internal wire strands, increasing the risk of rupture under pressure.
- 2.1.6 Use handles or other safe methods for transporting hydraulic equipment. Never lift it by hoses or swivel couplers.
- 2.1.7 Keep hydraulic equipment away from excessive heat or flames to prevent leaks, seal damage, and material weakening.
- 2.1.8 Avoid handling pressurized hoses, as escaping oil can penetrate the skin, causing serious injuries. If this occurs, seek immediate medical attention.
- 2.1.9 Repairs or servicing must only be performed by qualified hydraulic technicians.
- 2.1.10 Replace worn or damaged parts with original manufacturer parts to maintain performance and safety.
- 2.1.11 Elektriske pumper må ikke brukes i eksplosive atmosfærer. Sørg for at installasjonen overholder alle relevante elektriske forskrifter.
- 2.1.12 Unngå kontakt med bevegelige deler og trykksatte slanger.
- 2.1.13 Innvendige avlastningsventiler er fabrikkjustert og må ikke tukles med.
- 2.1.14 Kontroller motorspesifikasjonene for å unngå skade på grunn av feil strømkilder.
2.2 Sikkerhetsregler for elektriske pumper i BHC-serien
Følg disse ekstra forholdsreglene som er spesifikke for BHC-seriens elektriske pumper:
- 2.2.1 Bruk alltid vernehansker, boots, og øyebeskyttelse.
- 2.2.2 Unngå kontakt med høytrykksoljelekkasjer, som kan trenge inn i huden og forårsake alvorlige skader. Søk øyeblikkelig medisinsk hjelp hvis dette skjer.
- 2.2.3 Koble aldri fra hydrauliske koblinger mens de er under trykk.
- 2.2.4 Ikke forsøk å reparere et trykksatt system. Sørg for at trykkmåleren viser "0" før service.
- 2.2.5 Avoid pressurizing a disconnected male coupler to prevent potential failure.
- 2.2.6 Monitor the pressure gauge during pressurization and be prepared to stop immediately if needed.
- 2.2.7 Ensure all quick-disconnect couplings are securely attached before operation.
- 2.2.8 Only trained personnel should operate the pump.
- 2.2.9 Never leave the pump pressurized and unattended. Depressurize the system before leaving.
- 2.2.10 Do not exceed the maximum working pressure of the hydraulic system components.
- 2.2.11 The HE series electric pumps are rated for a maximum working pressure of 700 bar (10,000 psi). Never exceed this limit.
3.0 SPECIFICATIONS
3.1 Flow and Pressure Characteristics of BHE Series Electric Hydraulic Wrench Pumps
Note: Strømme, trykk, and current draw may vary depending on factors such as power supply, pump condition, and application.
3.2 Tekniske data
| Modell | Max Pressure (bar) | Flow at 0 bar (L/min) | Strømning ved nominelt trykk (L/min) | Power Supply | Noise (dB) | Oljekapasitet (L) | Weight Without Oil (kg) |
|---|---|---|---|---|---|---|---|
| BHC4TW | 700 | 7.0 | 0.6 | 220VAC | 75 | 5.0 | 27.0 |
Note: The pump operates efficiently between 20°C–40°C. For extreme temperatures, adjust hydraulic oil viscosity to maintain optimal performance.
4.0 INSTALLATION
4.1 Refueling Vent
- The refueling vent is non-sealed, and slight oil leakage during transport is normal. Drain hydraulic oil before shipping and refill before operation.
4.2 Oil Level
- Before starting the pump, ensure the oil level exceeds 2/3 of the upper oil level mark. Add hydraulic oil (ISO VG 32# recommended) if the level is below the lower mark.
4.3 Electrical Connections
- Electrical connections, including the power cable and handle cable, are pre-configured.
- Line circuit protection (115% of motor full load current) must be provided by the customer.
4.4 Hydrauliske koblinger
- Connect only matching male and female joints rated for 700 bar or higher. Sørg for at trykkmåleren viser "0" before connecting hoses.
5.0 OPERATION
5.1 Hydraulic Directional Valve
- Controls the flow to ports A or R.
- Port A: Høytrykks hydraulikkolje (maks 700 bar).
- Port R: Hydraulikkolje med lavt trykk (maks 100 bar).
5.2 Håndtak Drift
- Strømknapp: Starter og stopper motoren (hold type).
- Forhåndsknapp: Setter Port A under trykk (ikke-hold-type).
5.3 Justering av avlastningsventil
- Juster trykket ved å løsne låsemutteren og vri håndtaket på avlastningsventilen med klokken. Pass på at trykket ikke overskrider 700 bar.
6.0 VEDLIKEHOLD
Inspiser regelmessig alle systemkomponenter for lekkasjer eller skader. Koble pumpen fra elektrisk kraft og avlast alt hydraulisk trykk før du utfører vedlikehold. Reparasjoner på elektriske komponenter må utføres av kvalifiserte elektrikere som følger lokale forskrifter.
