Abstract
The utility model discloses an oil supply system of an oil press with a cooling loop. The oil supply system comprises a hydraulic station (1), wherein the hydraulic station (1) is used for supplying oil to a main oil cylinder (3) of the oil press (2) through an oil tube; the hydraulic oil in the main oil cylinder (3) is output to a top oil cylinder (4). The oil supply system is characterized in that after being fed into the cooling loop (8) for cooling through an output tube, the hydraulic oil in the top oil cylinder (4) flows back to the hydraulic station (1). By adopting the oil supply system, the service life of the hydraulic oil of the oil press can be prolonged, the working efficiency is improved, and meanwhile the temperature of the hydraulic oil in the hydraulic system is reduced by 5-6 DEG C.
Description
Technical field
the utility model relates to a kind of oil hydraulic press, especially a kind of oil hydraulic press hydraulic oil falling temperature technique, and concrete temple says a kind of oil hydraulic press oil supply system with cooling circuit.
Background technique
as everyone knows, oil hydraulic press long time continuous working can cause hydraulic oil oil temperature excess Temperature in oil hydraulic cylinder.The too high meeting of oil temperature brings following some harm:
1. hydraulic oil viscosity, volumetric efficiency and hydraulic work system efficiency all decline, and leak and increase, and even make machinery normally work.
2. the part of hydraulic system expands because of overheated, destroyed the original normal matching gap of relative movement part, cause that surface friction drag increases, hydrovalve is easily stuck, simultaneously, lubricant film attenuation, mechanical wear are increased, and result causes the precision-fit face of pump, valve, motor etc. because wearing and tearing and make its inefficacy or scrap too early.
3. accelerate rubber seal aged deterioration, the lost of life, even loses its sealability, and hydraulic system is seriously leaked.
4. fluid vaporization, moisture evaporation, easily make hydraulic element produce cavitation pitting; Fluid oxidation forms gluey sediments, easily stops up the aperture in oil purifier and hydrovalve, makes hydraulic system cisco unity malfunction.
Therefore, the too high meeting of hydraulic oil oil temperature has a strong impact on the normal use of machine, the working life of reduction hydraulic element, and increases the maintenance cost of engineering machinery.The solution that this be there is no at present.
Summary of the invention
The purpose of this utility model is because of the cooling means without good for the hydraulic oil in existing oil hydraulic press, cause hydraulic oil hot soak condition operation and occur the problem of the normal work of a series of impacts, design and a kind ofly supporting can in oil hydraulic press running, to hydraulic oil, carry out the oil hydraulic press oil supply system with cooling circuit of effectively granting.
The technical solution of the utility model is:
A kind of oil hydraulic press oil supply system with cooling circuit, it comprises hydraulic station 1, hydraulic station 1 is by master cylinder 3 fuel feeding of oil pipe and oil hydraulic press 2, hydraulic oil in master cylinder 3 exports top oil cylinder 4 to, and the hydraulic oil that it is characterized in that described top oil cylinder 4 enters cooling circuit 8 by output tube and is back to hydraulic station 1 after cooling.
Described cooling circuit 8 comprises cooler 5, water pump 6 and cooling tower 7, described cooler 5 is water-cooled cooler, the feed-water end of cooler 5 is connected with the delivery outlet of water pump 6 by water pipe, the water intake of water pump 6 is connected with the water outlet of cooling tower 7, and the water outlet of cooler 5 is connected with the backwater mouth of cooling tower 7 by return pipe.
The beneficial effects of the utility model:
The utility model can extend oil hydraulic press hydraulic oil and increase work efficiency working life.
The utility model can make the original 5-6 ° of reduction of hydraulic fluid temperature ratio in hydraulic system.
The utility model is simple in structure, and operating cost is low.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1.
A kind of oil hydraulic press oil supply system with cooling circuit, it comprises hydraulic station 1, hydraulic station 1 is by master cylinder 3 fuel feeding of oil pipe and oil hydraulic press 2, hydraulic oil in master cylinder 3 exports top oil cylinder 4 to, and the hydraulic oil of described top oil cylinder 4 enters cooling circuit 8 by output tube and is back to hydraulic station 1 after cooling.
Described cooling circuit 8 comprises cooler 5, water pump 6 and cooling tower 7, described cooler 5 is water-cooled cooler, the feed-water end of cooler 5 is connected with the delivery outlet of water pump 6 by water pipe, the water intake of water pump 6 is connected with the water outlet of cooling tower 7, and the water outlet of cooler 5 is connected with the backwater mouth of cooling tower 7 by return pipe.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
