Abstract
The utility model relates to a hydraulic oil tank cooling device, which comprises an oil tank body, and is characterized in that a cooling pipe is arranged in the oil tank body. The cooling pipe is connected with the inner wall of the oil tank body in a threaded manner and consists of a plurality of U-shaped units; a water inlet and a water outlet are respectively arranged at two ends of the cooling pipe; and a repair cover is mounted at the upper end of the oil tank body by the aid of screws. The hydraulic oil tank cooling device has the advantages that 1 the hydraulic oil tank cooling device is capable of preventing seeping water in an oil pipe joint from entering an oil tank, and also facilitates repairing and connecting of the cooling pipe, 2 the contact area of the cooling pipe with oil is large so that heat exchange effect is improved, 3 the cooling pipe is placed inside the oil tank so that the structure is compact and beautiful, and 4 compared with a water-cooling type oil cooler, the pipe cooling pipe is simple in structure and low in production cost.
Description
Technical field
The utility model relates to a kind of hydraulic oil tank cooling device, especially a kind of hydraulic oil tank cooling device that is used for hydraulic sterring engine.
Background technique
Boats and ships worked long hours in wide-angle as hydraulic sterring engine when summer, navigated by water the navigating area, and the rising that the oil temperature in the fuel tank can be very fast might surpass the required operating temperature of steering gear system, causes the damage of hydraulic element, has influenced the work of steering wheel.Like this with regard to require must be to the cooling of lowering the temperature of the fluid in the fuel tank.Two kinds of the most frequently used now types of cooling are air-cooled and water-cooled, and wherein the water-cooled application more extensively is a water-cooled oil cooling machine.This cooler is installed in the outside of fuel tank, is best cooling unit.But because steering wheel long-time wide-angle work seldom can take place continuously being in operation, just illustrate that this cooling arrangement general utilization is low, improved the cost of production of factory; Because cooler is installed in the outside of fuel tank, the spy has strengthened the external dimension of oil hydraulic pump group, is unfavorable for the installation of oil hydraulic pump group at steering gear flat.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, hydraulic oil tank cooling device that cost of production is low is provided.
According to the technological scheme that the utility model provides, a kind of hydraulic oil tank cooling device comprises the fuel tank casing, and feature is: be provided with cooling tube in described fuel tank casing.
Described cooling tube is connected by the inwall of screw thread with the fuel tank casing.
Described cooling tube is made up of several U type unit.
The two ends of described cooling tube are respectively equipped with water intake and water outlet.
The repairing lid is installed by screw in upper end at described fuel tank casing.
The utility model advantage and effect:
1, hydraulic oil tank cooling device described in the utility model can avoid the oil connection infiltration to enter in the fuel tank, also convenient for maintaining and connection water-cooling tube.
2, the area that contacts with fluid of cooling tube is big, improves heat exchange effect.
3, cooling tube is placed on the inside of fuel tank, and compact structure is attractive in appearance.
4, the tubular type cooling tube is compared with water-cooled oil cooling machine, and is simple in structure, cost of production is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: hydraulic oil tank cooling device comprises fuel tank casing 1, cooling tube 2, repair cover 3, U type type unit 4 etc.
The utility model comprises fuel tank casing 1, is provided with cooling tube 2 in fuel tank casing 1, and described cooling tube 2 is connected by the inwall of screw thread with fuel tank casing 1; Described cooling tube 2 is made up of several U type unit 4;
The two ends of described cooling tube 2 are respectively equipped with water intake and water outlet;
By screw repairing is installed in the upper end of fuel tank casing 1 and covers 3.
Cooling unit described in the utility model can cool off at fuel tank internal at fuel tank under the low situation of utilization ratio.Cooling tube 2 is connected with fuel tank casing 1 by screw thread, can conveniently carry out dismounting and maintenance to cooling tube 2.In fuel tank casing 1 upper end repairing is housed and covers 3, also be easy to open fuel tank casing 1 and keep in repair.Simultaneously cooling tube is made up of several U type unit 4, so as with reaching favorable cooling effect the fluid area of contact more.In use, the bottom of cooling tube 2 will reach the minimum liquid level of fluid, under the high situation of oil temperature, tubular type cooling tube 2 is poured cooling water circulate, and by heat exchange oily temperature is lowered the temperature.
