The utility model utilizes air-conditioning cooling technology, changes the original outer machine type of cooling of traditional air conditioner, traditional steaming Hair device removes, in needing the equipment lubrication petrol station that cools down, using inner coil pipe（Instead of the outer evaporator of former air-conditioning）Cooling medium, Compressor and inner coil pipe are welded to connect using pipe network.It is mainly characterized by：Compact-sized, liquid is contacted with heating surface, is passed Hot coefficient is high, low using the good failure rate of welded joints seal.Principle is to utilize liquid low temperature refrigerant, easily steam under low pressure It sends out, by arranging Bottomhole pressure, the outer medium of tube wall cooling tube and the heat for absorbing cooled medium, reaches refrigeration purpose, refrigeration is System is mainly made of four refrigeration compressor, condenser, evaporator and throttle valve basic element of character.Connected successively with pipeline between them It connects, forms a closed system, refrigerant constantly circulates in systems, and generating state variation carries out heat with the external world Amount exchanges.After the basic principle liquid refrigerant of refrigeration system absorbs cooled object heat in evaporator, it is vaporized into The steam of low-temp low-pressure, by compressor sucking, be compressed into after the steam of high pressure-temperature be discharged into condenser, condenser front installation, Axial flow blower, raising increase heat dissipation effect by the air velocity of radiator core.When fan rotates, suction is generated to air Effect, is allowed to flow in an axial direction.For air stream from the front to the back by radiator core, the coolant liquid acceleration for flowing through radiator core is cold But, reach cooling optimum efficiency.It is condensed into highly pressurised liquid, is the refrigerant of low-pressure low-temperature, is again introduced into through throttle valve throttling Evaporator heat absorption vaporization, achievees the purpose that circularly cooling.In this way, refrigerant is in systems through pervaporation, compression, condensation, throttling Four basic processes complete a refrigeration cycle, and evaporator is the equipment for conveying cold in this.Refrigerant absorbs quilt wherein The heat of cooling object realizes refrigeration.Compressor is heart, plays a part of sucking, compression, conveying refrigerant vapour.Pass through pressure Contracting machine is continual to work, and will be sent to higher-pressure region in the heat absorption to refrigerant of low-pressure area again, finally also just realizes The cycle of entire refrigeration plays the role of temperature adjusting.

The energy transmission on each device that control system passes through system, transfer, loss principle, system control method are different, To produce different power-saving technologies, to realize the automatic start-stop control of cooling system, reach the thermostatic control of device temperature, The drawbacks of restarting need to first be preheated by avoiding when traditional cooling system uses in winter, improve effective operation ratio of equipment.When DCS sends out order startup heating device, heating-stopping apparatus when temperature is higher than 30 DEG C when tank temperature is less than 25 DEG C；When oil return temperature DCS, which is sent out, when degree is higher than 46 DEG C starts cooling device order, stops cooling device when less than 30 DEG C.

The advantages of below to the utility model or principle illustrate.

This cooling technology is suitable for the Lubricating-oil Station of various large body equipment to speed reducer and the high running device of monomer etc.. Lubricating-oil Station is the heart of thin Oil Lubricating System, and effect is that lubricating oil is forcibly sent to machine friction position, is reduced The equipment high temperature problem that equipment is brought by high operating, Lubricating-oil Station are mainly used for the dynamic and static pressure of the machinery equipments such as metallurgy, mine, cement Or in the centralized lubricating system of slide shoe bearing.The cooling technology main advantage is, substantially reduces vibrations and the noise of cooling tower, Reduce the pollution to environment, the chain operation of automation improves 80%, 100% and avoids breaking because cooling water corrodes pipeline and cooler Oil emulsion contamination phenomenon caused by damage while reaching equipment high efficiency cooling effect, 100% can save water resource, to spare part And maintenance cost reduces by 70% or so, is effectively supervised compared to traditional cooling process equipment and 50% or more operating cost saving, equipment Shield, which improves 80% pair of main equipment accident rate, reduces by 80%.
