Abstract

1) Field of invention

Hydraulic Engineering

2) The technical problem to be solved by the invention

The oil tank in the hydraulic circuit needs to be prepared for the deterioration of the circuit's operation function due to the mixing of air and the free flow of oil on the surface contacting the air unit during the circuit operation.In particular, the oil tank in the hydraulic circuit for moving or underwater work It is sensitive to the difference in capacity due to the loss of and is vulnerable to tipping or severe vibration.

Description

External system blocking and volume correction mechanism of hydraulic circuit oil tank and liquid chemical storage container

Hydraulic Engineering

The oil tank in the hydraulic circuit needs to be prepared for the deterioration of the circuit's operation function due to the mixing of air and the free flow of oil on the surface contacting the air unit during the circuit operation.In particular, the oil tank in the hydraulic circuit for moving or underwater work It is sensitive to the difference in capacity due to the loss of and is vulnerable to tipping or severe vibration.

2 is a cross-sectional view when using a rod for capacitive detection and piston support

In order to solve such a problem, the present invention was produced by removing the air contact surface in the tank and smoothly accommodating the change in volume. Referring to FIG. 1, the principle is that the stroke length is appropriately made. By installing the cylinder in the oil tank, the oil surface is isolated from the outside, and the piston moves according to the change of the working oil volume. The tube ② and the piston ③ inside the oil tank ① are corrosion-resistant materials. One side of the cylinder opened to the oil inside the oil tank and the other side to the oil system outside the oil tank to make it resistant to corrosion by plating or coating. It is configured to control the pressure and volume of oil by moving the piston according to the movement.If the air in the circuit is discharged and sealed when filling the oil tank for the first time, it is isolated from the outside during use. It can keep the state.

In the case of FIG. 2, the rod for the capacity detection and the piston support is configured together, so that when the hydraulic oil is filled into the oil tank, the capacity can be arbitrarily adjusted or the capacity in use can be easily grasped.

In this way, by separating the oil surface from the outside, it is possible to prevent the outflow of the working oil even when the oil tank is overturned or severe vibration, and the problems such as the change in the surface height of the existing oil tank according to the flow of the working oil in the oil tank such as the introduction of DRAIN oil. Resolved.

In particular, in the case of the hydraulic circuit for underwater work, it is possible to expose the oil tank in the water, so there is also an effect such as not needing a separate space for segregation with the underwater part.

The existing air filter (air filter) and oil level indicator can be replaced at the same time, and the capacity of the oil tank can be detected almost unaffected.

In addition, in the case of a container (TANK or VESSEL) that causes problems when exposed to air or stores volatile liquid chemicals, the problem can be solved by buffering the volume difference caused by temperature change by using this apparatus.

Claims (2)

One side of the cylinder that is resistant to corrosion by plating or coating tubes and pistons with corrosion-resistant materials inside oil tanks or vessels. It is configured to open the inside, open the other side to the oil tank external system, and to control the pressure and the volume of the oil tank or the container by moving the piston in accordance with the change of the liquid content. In claim 1, as shown in Fig. 2, the rod for capacitive detection and piston support is further configured by combining with a dust stopper.
