Background technique
Due to hydraulic system meeting distribute heat in the process of work of concrete mixer, so, before prior art, this research is mainly concentrated on to the aspect how to lower the temperature, and hydraulic system heating measures is seldom studied.But; for being in the concrete mixer that such as Northeast Area of China etc. is high and cold weather for a long time; because it can be the operating mode operation of less than-20 DEG C in temperature, run for a long time; add the fabricated metals heat dissipation rates such as the hydraulic oil container of pump truck, joint very fast; therefore, the appearance of the problems such as hydraulic oil condensation can usually be caused.Even if what pump truck added is anti frozen liquid force feed (such as 32# hydraulic oil), but the kinematical viscosity of hydraulic oil-20 DEG C time can reach about 1000mm2/s, now can there is oil hydraulic pump and inhale sky in hydraulic system, cannot normally work at all.
And the too low result caused of hydraulic fluid temperature can make hydraulic system at the beginning of normal unlatching, occur that hydraulic system speed slowly or the phenomenon of pressure drag; The phenomenons such as outside can show as the structure such as supporting leg, jib and be slow in action, and pumping cannot get a desired effect, rate of pumping is slow.
The mode processing above-mentioned phenomenon in prior art is: 1. adopt the heating of throttling secondary circuit, and it is by the throttling of throttle valve and relief valve and overflow, and make hydraulic energy become heat energy, oil liquid temperature raises.Meanwhile, not easily deterioration is rotten can to ensure hydraulic oil.2. adopt electric heater heating, when adopting the heater in fuel tank, they are arranged lower than fuel tank liquid level, to ensure to be flooded by fluid all the time.
But above-mentioned prior art also has following major defect:
1. need shift to an earlier date preheating, take the operating time.
2. adopt the method for throttling secondary circuit heating, need to transform hydraulic system or add separately heating secondary circuit, cost is higher.
3. adopt electric heater to heat, consider that its surface power density is for hydraulic oil liquid institute allowed band, in order to avoid fluid is overheated and occur rotten, therefore, be difficult to control.
