[0005] 2. When the hydraulic oil temperature is low and the engine needs to be warmed up, since all the hydraulic oil in the hydraulic oil tank participates in the circulation, the oil temperature rises slowly, the viscosity is high, the hydraulic action is slow, and it will cause a certain degree of damage to the hydraulic components. And heating up the car for a long time to raise the oil temperature will cause the engine to work hours and waste fuel
And when the hydraulic oil temperature is high, limited by the volume of the hydraulic oil tank, the heat dissipation on the surface of the hydraulic oil tank is small, and the oil temperature must be reduced by means of the hydraulic oil radiator, which increases the heat dissipation area and volume of the hydraulic oil radiator
[0006] In summary, the prior art lacks a real-time, effective and precise method, device and system for controlling hydraulic oil temperature and oil quantity

Embodiment 1

[0033] Embodiment 1, when the hydraulic oil tank is a single hydraulic oil tank, the hydraulic oil tank main partition 300 can be the main cavity in the hydraulic oil tank, and the hydraulic oil tank sub-partition 400 can be the hydraulic oil tank The secondary cavity in the main cavity, wherein the amount of hydraulic oil in the main cavity is more than the hydraulic oil in the secondary cavity, that is, the amount of hydraulic oil in the main cavity can generally meet the requirements of the hydraulic system For normal use, the amount of hydraulic oil in the auxiliary cavity is for backup.

Embodiment 2

[0034] Embodiment 2, when the hydraulic oil tank is a plurality of hydraulic oil tanks, the hydraulic oil tank main section 300 can be the main hydraulic oil tank, and the hydraulic oil tank sub-section 400 can be the auxiliary hydraulic oil tank, wherein the main hydraulic oil tank The amount of hydraulic oil in the oil tank is greater than the amount of hydraulic oil in the auxiliary hydraulic oil tank. That is, the amount of hydraulic oil in the main hydraulic oil tank can generally meet the normal use of the hydraulic system, while the amount of hydraulic oil in the auxiliary hydraulic oil tank is reserved.

[0035] In addition, the hydraulic oil tank main partition 300 and the hydraulic oil tank sub-region 400 can also be configured in multiples (for example, more than two) according to actual conditions, each of which includes any one or a combination of the above-mentioned embodiments 1 and 2, and can connected in series and / or parallel.

Abstract

The invention discloses a control method, equipment, system of a hydraulic oil tank, and engineering machinery. The hydraulic oil tank comprises a hydraulic oil tank main partition and a hydraulic oil tank accessory partition. The control method comprises the following steps: receiving the hydraulic oil temperature of the hydraulic oil tank main partition; and controlling the work of the hydraulic oil fluid of the hydraulic oil tank main partition and / or hydraulic oil fluid of the hydraulic oil tank accessory partition according to the hydraulic oil temperature. According to the control method disclosed by the invention, only a needed amount of hydraulic oil participates in circulation, so that the oil temperature is quick to rise; the working hours of an engine are small; little fuel oil is wasted; the using cost is reduced; the hydraulic oil fluid is low in viscosity, so that the hydraulic oil fluid generates little harm to hydraulic elements; the varying range of the hydraulic oil temperature is small; the heat dissipating effect is good; the service life of the hydraulic oil is prolonged; therefore, the temperature of the hydraulic oil and the amount of the hydraulic oil can be effectively and accurately controlled in real time.

Description

technical field [0001] The present invention relates to engineering machinery, in particular to a hydraulic oil tank control method, a hydraulic oil tank control device, a hydraulic oil tank control system, and an engineering machine. Background technique [0002] In construction machinery (such as hydraulic excavators, etc.), the hydraulic oil tank is an important part of the hydraulic system. It mainly plays the role of storing hydraulic oil. On the basis of the maximum cavity capacity of the pipeline (or oil circuit) and accessories, it is guaranteed not to be sucked and a certain amount of surplus is reserved. [0003] In the prior art, the hydraulic oil tank is a whole, and the hydraulic oil in the entire oil tank and the hydraulic system all participates in the working cycle. Driven by prime movers such as engines, hydraulic power components (such as main pumps) absorb oil from the hydraulic oil tank to provide hydraulic oil with a certain pressure and flow for hydrau...
