Pressurizing oil tank of concrete pump

Abstract

The invention discloses a pressure boost sealing oil tank of concrete pump automobile, which is characterized by the following: opening air inlet, oil suction hole and oil return hole on the oil tank; connecting the oil suction hole with the oil pump of concrete pump automobile; connecting the air inlet with the air reservoir through gas supply device. The invention reduces the noise of oil pump and lengthens the lifetime, which optimizes the entire pump automobile structure.

Description

technical field [0001] The invention mainly relates to the field of concrete pump trucks in engineering machinery, in particular to a pressurized fuel tank of a concrete pump truck. Background technique [0002] In the prior art, the concrete pump trucks all use normal-pressure oil tanks. With the continuous increase of the pumping capacity of the pump trucks, the required oil pump displacement is also increasing. In order to ensure the pressure of the oil suction port, the corresponding oil pump The tubes are also getting bigger. Since the oil pump of the pump truck is generally arranged in a narrow area between the chassis girders, in order to reduce the loss along the oil suction pipeline, the domestic pump truck basically uses a fixed turret as a fuel tank at present to ensure that the distance between the fuel tank and the oil pump is relatively short. In this way, with the increase of the oil suction pipe, the structure of the fixed turret must allow enough space for ...

Problems solved by technology

In this way, with the increase of the oil suction pipe, the structure of the fixed turret must allow enough space for the oil suction pipe, so that the stress of the fixed turret becomes worse, and the ability to resist fatigue damage is reduced. Therefore, in the limited space of the pump truck How to arrange the oil suction pipe with large diameter has become a difficult problem
