Such as processing metal, plastics, rubber, timber, powder product, it is usually used in pressing process and block pressing forming process, hydraulic
Machine includes hydraulic press and hydraulic press.Hydraulic press, as power source, passes through hydraulic oil by the active force of pump hydraulic by hydraulic pump
Pipeline enters oil cylinder or piston, then makes hydraulic oil so that oil cylinder or piston is done work in fuel tank circulation by check valve, to complete
Certain mechanical action.Hydraulic press during the work time, due to bearing larger load, so that hydraulic oil heating is quickly, for a long time
The normal operation of equipment is influenced using will lead to analysis of hydraulic oil overheat, the effective power of entire hydraulic oil system is reduced, drawing
The cancel closedown for playing equipment, so that production capacity is reduced, so hydraulic oil has to pass through cooling system and cooled down.However, existing
That there are cooling effects is bad for hydraulic oil cooling system, and oil temperature is still higher, unit exception or shutdown caused by being easy because of high oil temperature.
If CN205895774U is prior art discloses a kind of hydraulic oil cooling device, the suitable temperature of hydraulic cylinder oil is
35~55 DEG C, during hydraulic cylinder works, due to compression etc., it will cause oil temperature and gradually rise, oil temperature once reaches 60
DEG C or more when, be easy to cause the stability and ability to work decline of the operation of hydraulic cylinder apparatus, also thus hydraulic oil can be caused to become
Matter and be not available, meanwhile, the excessive high oil temperature of time-out or even also will cause hydraulic system leakage and failure, cause uneasiness
Full contingency, convenient in time thus and reliable cool down for hydraulic oil is the reliable guarantor of hydraulic system safe operation

A kind of individual hydraulic power unit disclosed in art, using electronic or hydraulic-driven fan-cooled radiator, principle and fan
Equally.Exist through this radiating mode of practice analysis following insufficient: because sucking wind when using wind-force to hydraulic oil progress cooling down
Temperature be equal to environment temperature, then the temperature for blowing out wind also differs smaller with environment temperature, and cooling effect is poor.Because of the wind
Cold type radiator be it is similar with fan structure, wind-force is not concentrated, while the body clearance that quite a few wind energy passes through radiator
Leakage, so leading to cooling down low efficiency.If Hydraulic Equipment cooling effect is poor, hydraulic fluid temperature will be increased, if
Standby failure (mechanism alarms, stops working, pressure reduces, leakage increases) rate increases.Especially a few thing environment temperature is higher,
The frequent occasion of equipment work, equipment failure rate will greatly increase, and influence equipment work efficiency, increase working service cost.
