Abstract
A kind of oil tank leakage detection device, it is by waiting to examine the oil tank assembly, pushing cylinder, double-acting cylinder, relief pressure valve, electrical apparatus switch, two-position four-way solenoid valve, return oil tank, oil pump and oil line make up, its characteristic is to examine the oil tank inner fill with liquid, the upper portion is sealed with the cover, the inferior part is connected with pushing cylinder through the oil line, the oil line communicates all hydraulic components; an oil pump supplies oil to a hydraulic system through an oil pipe, an electric switch controls a double-acting oil cylinder to move left and right through controlling a two-position four-way solenoid valve, a pressure reducing valve controls detection pressure, when the double-acting oil cylinder moves left, a pushing cylinder piston is pushed to move left, liquid in an oil tank assembly to be detected is pressurized, liquid seeps out at a leakage position, a mark is made at the seeped position, the electric switch controls the double-acting oil cylinder to move right through controlling the two-position four-way solenoid valve, and an electric welder performs; and after repair welding, the detection is continued until no leakage exists. The device has simple structure and convenient use, can accurately find the position needing repair welding, and improves the quality and the labor productivity.
Description
Technical Field
The utility model relates to hydraulic pressure spare detection area, in particular to oil tank leak testing field.
Background
At present, the leakage detection of the oil tank mainly adopts two methods, 1, after the oil tank is sealed, compressed air is filled, soapy water is brushed at a welding seam, and air bubbles are generated at the air leakage position; 2. after the oil tank is sealed, compressed air is filled into the oil tank and is placed into the water pool, and air bubbles are generated at the air leakage position; the first method has difficulty in eliminating all leaks, and the second method has difficulty in determining the exact location of the vent.
Disclosure of Invention
The utility model provides a new method for detecting the leakage of the oil tank to overcome the defects;
a kind of oil tank leakage detection device, it is by the oil tank assembly to be examined, push cylinder, double-acting cylinder, relief pressure valve, electrical apparatus switch, two-position four-way solenoid valve, return oil tank, oil pump and oil line make up, its characteristic is to examine the oil tank inner filling liquid, the upper portion is sealed with the cover; the oil pipe is used for communicating all the hydraulic elements; the oil pump supplies oil to the hydraulic system through the oil pipe, the electric switch controls the double-acting oil cylinder to move left and right through controlling the two-position four-way electromagnetic valve, and the pressure reducing valve controls the detection pressure.
Drawings
Fig. 1 is a front view of the present invention.
In the figure, an oil tank assembly (1) to be detected is provided, a sealing cover (1-2) is arranged at the upper part of a tank body (1-1) and is fastened by bolts, and an outlet at the lower part of the tank body is connected with an oil pipe; the piston of the double-acting oil cylinder (3) is connected with the piston rod of the pushing cylinder; an oil pipe of the pressure reducing valve (4) is connected with an oil inlet pipe; the electric switch (5) is used for controlling the electromagnet of the two-position four-way electromagnetic valve (6) to be switched on or switched off, the oil return tank (7) is used for returning oil, the oil pump (8) supplies oil to the double-acting oil cylinder through the two-position four-way electromagnetic valve, and the oil pipe (9) communicates the hydraulic element;
