A plastic hydraulic oil tank anti-oil return impact rotational molding

Abstract

The invention discloses a rotational molding type plastic hydraulic oil tank capable of preventing oil return impact. The rotational molding type plastic hydraulic oil tank comprises a tank body (1), and the tank body (1) is provided with an oil return port (11), an oil addition port (12) and an exhaust port (13). The rotational molding type plastic hydraulic oil tank is characterized in that a buffering boss (15) is arranged on the inner surface of the bottom wall of the tank body (1), and the oil return port (11) is opposite to the buffering boss (15) in the vertical direction; a lower baffle plate (16) is arranged at the side part, facing the end with the exhaust port (13) and the oil return port (11) of the tank body (1), of the buffering boss (15) and is arranged inside the tank body (1), the lower edge of the lower baffle plate (16) is connected to the bottom wall of the tank body (1), and gaps (17) are reserved between the left edge and / or the right edge of the lower baffle plate (16) and the corresponding side walls of the tank body (1). According to the rotational molding type plastic hydraulic oil tank, by arranging the buffering boss and the lower baffle plate, the oil return pressure is lowered, and therefore normal-pressure ports such as the oil addition port and the exhaust port of the hydraulic oil tank are protected finally and do not leak easily, and the service life is prolonged.

Description

technical field [0001] The invention relates to a hydraulic oil tank, in particular to a plastic hydraulic oil tank anti-oil return impact rotational molding, the hydraulic oil tank is an oil storage tank for storing hydraulic oil in hydraulic systems on agricultural machinery, engineering machinery or vehicles. Background technique [0002] In the hydraulic system of vehicles, agricultural machinery or construction machinery, the hydraulic oil returned through the oil return line has a high temperature (above 100°C) and a high oil return pressure accompanied by a large number of air bubbles. Impacted by the oil return pressure during long-term use, stamping leakage is prone to occur at the normal pressure interface such as the filling port or exhaust port of the hydraulic oil tank. This is a ubiquitous and insurmountable problem in existing hydraulic oil tanks. Contents of the invention [0003] The object of the present invention is to provide a plastic hydraulic oil ta...
