|---|---|---|---|---|---|---|---|
| hydraulic system,construction machinery,wind energy,nuclear power,vessel equipments,exploiting equipments in diggings, coal mine. | GB,FR,TR,IT,MX,GLOBAL | Medium: Hydraulic oil with viscosity up to 320 mm²/s (VG320 high-viscosity lubricating oil is fully compatible) Oil inlet temperature: Standard ≤90°C, customized max 130°C Rated working pressure: 16 bar Ambient environment: Indoor & semi-outdoor general industrial workshops; can be upgraded for dust-proof, low-temperature, plateau working conditions Oil flow range: 6–200 L/min, matched with different model pump displacements | DFLS series belongs to self-circulating air-cooled oil cooler developed by DEO Ningbo Machinery Co., Ltd, a standardized integrated closed-loop cooling equipment for hydraulic & lubrication oil systems. It is an independent cooling unit integrating cooling radiator, circulating oil pump, cooling fan, filter and control accessories, categorized as auxiliary heat dissipation equipment for industrial fluid power systems. | Continuous heat removal for hydraulic/lubricating oil, stabilize oil temperature within safe operating range, prevent oil deterioration caused by overheating. Solve the failure risk of ordinary coolers under pulse oil return, avoid pressure shock damage to heat exchanger core. Independent closed circulation loop separates cooling circuit from main hydraulic circuit, eliminates main system pressure fluctuation interference on cooling performance. Extend service life of hydraulic seals, oil pumps, valves and reduce equipment failure rate. Lower oil viscosity fluctuation, stabilize system transmission efficiency and reduce energy consumption of main machine. | DFLS adopts independent closed self-circulation loop, totally separated from host hydraulic oil circuit: Built-in circulating pump extracts hot oil from host oil tank / lubrication loop. Hot oil is delivered to aluminum/copper radiator core; axial fan blows cross air flow to take away oil heat via forced air convection. Cooled oil flows back to the equipment oil tank/lubricating point to complete one cooling cycle. Optional built-in temperature bypass valve (45–55°C opening threshold): When oil temperature is low in cold start, oil bypasses radiator directly to accelerate system preheating, avoiding low-temperature high-viscosity pressure surge. Optional pressure bypass valve protects the unit from instantaneous flow & pressure spikes. Optional temperature/pressure switches realize over-temperature & over-pressure alarm to realize automatic operation monitoring. | Medium & Viscosity Requirements Mainly applicable to hydraulic oil VG46–VG320; when oil viscosity exceeds 30 cSt, pressure drop calculation needs viscosity correction coefficient. Oil medium must be clean; filter is mandatory for heavy pollution working conditions. Installation Special Requirements The unit can be floor-mounted or bracket-mounted; mounting base must add shock-absorbing gaskets to reduce vibration transmission. Oil inlet direction optional left (INL) / right (INR) to match different pipeline layouts. Oil suction pipeline of built pump must be free of air leakage, otherwise circulation flow declines and cooling capacity drops sharply. Reserve ventilation space around radiator, blockage of air inlet/outlet is forbidden to avoid insufficient heat dissipation. | Built-in Standard Supporting Components Circulation oil pump (different displacement options: 6–200 L/min) Cooling axial fan (4/6 poles, 250–900mm fan diameter, 380V/220V motor) Aluminum fin heat exchanger core (304 stainless steel/copper fins optional) Oil inlet/outage flange & pipe connectors (G3/4, G1, G1-1/4, G1-1/2, SAE standard ports) |
| wind energy | Applicable fluid: Lubricating oil, hydraulic oil with good lubricity, no solid impurities, chemically compatible with pump materials Kinematic viscosity range: 12 ~ 20000 cSt Fluid operating temperature: -40℃ ~ 100℃ Built-in relief valve standard setting pressure: 5 ~ 25 bar | DK series is low-noise helical external gear positive displacement pump independently developed by DEO Ningbo Machinery Co., Ltd, belonging to industrial lubrication & hydraulic auxiliary fluid conveying equipment. It is divided into standard DK model for general industry and DKF special model exclusive for wind power generation industry. Complete pump unit MDK series (pump + motor + bell housing coupling) is also available as integrated driving assembly. | Continuous stable delivery of lubricating/hydraulic oil to mechanical friction pairs (gears, bearings, sliding rails) to form oil film, reduce abrasion and friction heat. Circulate hot oil out of lubrication points and send it to matching oil coolers to realize heat dissipation and stabilize oil temperature. Provide constant pressure oil supply for hydraulic auxiliary circuits, filtration systems and oil recovery loops. Built-in relief valve serves as overpressure protection to avoid pipeline & equipment damage caused by system pressure surge. Helical gear structure lowers running noise compared with straight gear pumps, improving workshop operation environment. DKF wind power customized version enhances anti-shock, anti-vibration performance to adapt wind turbine frequent variable speed & alternating load conditions. | 24/6 | Medium Special Requirements Oil must be free of metal chips, sand and other solid impurities; particle impurities will scratch gear surfaces and wear bushings rapidly. For ultra-high viscosity oil (>1000 cSt), reduce pump speed to avoid excessive suction resistance and cavitation. Rotation & Operation Limits Strictly follow marked rotation direction on pump nameplate; reverse rotation invalidates sealing and causes leakage failure. Prohibit dry running without oil medium; dry friction burns shaft bushings and gears in short time. Built-in valve only for transient pressure protection; continuous overflow operation will lead to pump overheating and early wear. Installation Special Requirements Pump inlet pipeline must be airtight without air leakage, otherwise insufficient suction flow & cavitation occur. Inlet pipe diameter cannot be smaller than pump inlet port to avoid flow restriction and pressure loss. MD pump unit assembly: Bell housing and motor shaft must maintain coaxiality; mis | Standard Built-in Components of DK Pump Transmission helical gear, driven gear, copper bushings, cast iron pump casing, end cover, rotary shaft seal, NBR/FKM sealing rings, thrust ring, positioning pins, built-in relief valve assembly (valve core, spring, adjusting screw & lock nut). |
