Oil-water tank integrating a hydraulic oil tank with a heat radiating water tank

The invention relates to an oil-water tank integrating a hydraulic oil tank with a heat radiating water tank. A water tank is additionally arranged in an original hydraulic oil tank, and an oil return box (1), the water tank (2) and an oil absorption tank (3) are welded into a whole. The oil return box (1) and the oil absorption tank (3) are communicated with each other by heat radiating oil pipes (5) arranged in the water tank (2). When a hydraulic system works, hydraulic oil enters the oil return box (1) through an oil return pipe (4), then flows in the oil absorption tank (3) by the heat radiating oil pipes (5) arranged in the water tank (2) and then flows past a filter element (6) to enter an oil absorption pipe (7). By the repeated circulation, the water in the water tank (2) absorbs part of the heat of oil liquid by taking advantage of the heat radiating oil pipes (5) so as to slow down the rising of the oil liquid temperature. If the oil liquid temperature is over-high, over-hot ...

Process for using hydraulic driven trailer wheel for hinged jointed tractor

The invention relates to a method for implementing the use of hydraulically-driven trailer wheels in an articulated tractor. The method is implemented based on the prior articulated tractor with addition of a hydraulic driving device which consists of a hydraulic pump (3), a reversal valve (4), a trailer axle (7), an oil motor (8), a hydraulic oil tank (6) and a pipeline. The hydraulic driving device directly drives the shaft of the trailer axle (7). When driving on a normal road, the hydraulic driving device is not started and the heat-ended driving wheel is actuated. When climbing on a road with large slope or driving on a muddy road, the heat-ended driving wheel is actuated and simultaneously the hydraulic driving device is started, so that the trailer wheel acts as a driving wheel, thereby realizing four-wheel driving. The method can greatly improve the traction and attachment properties of the articulated tractor without changing the existing structure and purpose of the articulated ...

Method for banking in water

The invention discloses a method for embanking in water. It is characterized in that: a working bin is arranged in a workboat; an immersion opening is arranged at the bottom of the working bin; a sandbag is arranged in the working bin filled with embanking materials; and then the filled sandbag is immersed in water from the immersion opening. The invention can perform sandbag filling construction to the size and thickness of filling sandbags controllably, with strong applicability to construction environment, being safe, rapid and economical.

Pen-type massage rod
