Problems solved by technology
However, in cold environments such as winter, there is no need for a larger air cooler to cool the hydraulic oil. If the volume of the air cooler is increased simply for hot seasons such as summer, it will not only increase the layout space of the air cooler, but also increase the size of the air cooler. It causes unnecessary waste of energy in winter and other situations where it is unnecessary to use a high-power air cooler

The invention discloses a hydraulic oil cooling system and engineering machinery having the same. The hydraulic oil cooling system comprises a water tank, a cooling water tank, a heat exchange pipe and a temperature sensor, wherein the water tank is arranged in a cab; the cooling water tank is connected with the water tank through a pipe, is arranged on a vehicle, and is provided with an exchange pump on the pipe; the heat exchange pipe is arranged in the cooling water tank, is connected with a hydraulic oil way, and is used for enabling hydraulic oil in the hydraulic oil way to exchange heat with liquid in the cooling water tank when flowing through the heat exchange pipe; the temperature sensor is arranged in the cooling water tank, and is used for detecting the water temperature in the cooling water tank; and when the water temperature in the cooling water tank exceeds a set value, the exchange pump operates to enable liquid in the water tank to be exchanged with the liquid in the cooling water tank. Through the structure, the hydraulic oil can be cooled through cold air in the cab in spring and summer, so that the further cooling problem of the hydraulic oil system in such high-temperature weathers as in summer is solved, and the increment of the volume of an air cooler for the cooling of the hydraulic oil way is not needed.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a hydraulic oil cooling system and an engineering machinery with the same. Background technique [0002] Concrete pump truck is a common construction machinery, and the hydraulic system of concrete pump truck is usually a high-pressure and large-flow system. According to the test, the temperature of the hydraulic system of most concrete pump trucks can be as high as 70 degrees after about 40 minutes of use in summer, and the temperature of the hydraulic system can be as high as 80 degrees or more after about two hours of use. The normal temperature of the system should be around 50 degrees. [0003] The heating of the hydraulic system of the concrete pump truck directly affects the normal operation of the concrete pump truck. The heating will cause the viscosity of the working fluid to drop, the seals in the hydraulic system will deteriorate and fail at high temperatures, an...
