Description
Technical field
The utility model relates to a kind of oil cooler.
Background technique
At present, because oil is in cyclic process, absorb the heat that place's frictions such as bearing produce, thus temperature constantly raises, for ensureing that unit safety reliably runs.Must Oil-temperature control (require the highest 60-65 DEG C that is no more than, also be not less than 35-40 DEG C) within the limits prescribed temperature too high may the parts such as bearing overheated and damage.And lubricant oil life time can be reduced, the too low meeting of temperature makes lubricating oil viscosity increase, increase friction work consuming, even purport plays machine vibration, so existing employing oil cooler solves the problem, its oil cooler heat-transfer pipe heat exchange area is large, and small product size is little, lightweight, oil cooler is applicable to the cooling of the low and comparatively clean fluid of viscosity; Oil cooler can be applicable to the industries such as plastics machinery, hydraulic equipment, air compressor, the cunning system of thin oil, fluid coupling, electric installation.This Series Oil cooler product all can manufacture and design according to customer requirement from small-sized to medium-and-large-sized, wide coverage, its existing defects in use and heat-transfer effect of existing oil cooler.
Summary of the invention
The technical problems to be solved in the utility model is to provide the oil cooler of a kind of good airproof performance, compact structure.
In order to solve the problems of the technologies described above, the utility model provides a kind of oil cooler, it forms by housing is coated, described housing two ends are provided with into water lid and water return cover, be provided with tube-expanding type sealing Sealing in described water inlet lid and water return cover, described tube-expanding type sealing Sealing side is provided with fastening piece, and described housing upper end is provided with discharge oil inlet and discharge oil export, described shell people inside is provided with spiral guiding plate, and described spiral guiding plate lower end is provided with the fixed block be fixedly connected with housing.
Described housing is set to cavity seamless steel pipe, and described housing adopts copper tube to roll out radiation fin structure.
Compared with prior art, the utility model advantage is:
Oil cooler adopts naked pipe (fin is not rolled on surface) formula heat-transfer pipe, and pipe external limiting membrane heat-transfer coefficient is high, and contamination resistance is strong.Oil cooler cooling tube adopts high-quality copper tube, and is processed into fin shape radiating fin, and small product size is little, heat exchange area is large.Oil cooler spiral guiding plate, makes cooled liquid spirality continuous uniform roll and flows, overcome the cold/heat exchange efficiency that deflector type guide plate produces.Oil cooler adopts tube-expanding type sealing, overcomes the disadvantageous changes that material produces after high-temperature soldering.Oil cooler structure is functional, and sealability is stablized, and heat transfer efficiency is high, compact structure, floor space are little.Utilize this equipment that two kinds of liquid mediums with a fixed difference difference can be made to realize heat exchange, thus reach reduction oil temperature, especially to turbine oil cooling, can ensure that the equipment such as steam turbine normally run.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model oil cooler.
Embodiment
As shown in Figure 1, a kind of oil cooler, it forms by housing 1 is coated, described housing 1 two ends are provided with into water lid 2 and water return cover 3, be provided with tube-expanding type sealing Sealing 4 in described water inlet lid 2 and water return cover 3, described tube-expanding type sealing Sealing 4 side is provided with fastening piece 5, and described housing 1 upper end is provided with discharge oil inlet 6 and discharge oil export 7, described shell people 1 inside is provided with spiral guiding plate 8, and described spiral guiding plate 8 lower end is provided with the fixed block 9 be fixedly connected with housing 1.
Described housing 1 is set to cavity seamless steel pipe, and described housing 1 adopts copper tube to roll out radiation fin structure, and oil cooler should be arranged on system oil return road or lower than in the system of design pressure, oily side pressure should higher than water side pressure.Oil cooler should check after installing to be connected with piping attachment instrument whether correct tight, fuel-displaced and outlet valve is first closed when enabling, unclamp venting plug, slowly open oil-feed and inlet valve, make to be full of You Heshui in cooler, pull tight venting plug, water all becomes state of rest with oil, make oil, water temperature difference reduces gradually, when after profit thermal equilibrium, open water outlet and outlet valve, require to regulate inflow according to thermal equilibrium, cooler should adopt clean fresh water, clean water should not configure water filter, cold season uses cooler, the water in cooler and oil should be drained time inactive as far as possible, in order to avoid bursting by freezing cooler, when cooler is stopped using, profit should be closed successively and enter valve, profit expulsion valve, unclamp draining, plug screw on oil drain out, drain the residual water in cooler and oil.
Working pressure: normal operating pressure 1.6MPa; Design maximum service pressure 5MPa is needed according to user; Allow hydraulic oil maximum temperature 120 DEG C.Power plant: A, AC motor AC380V, AC220V; B, direct current generator DC24V, DC12V; C, oil hydraulic motor 8ml/r ~ 12.5ml/r; D, anti-explosion motor AC380V, DC24V.
