Description
Technical Field
The utility model belongs to the technical field of the die casting machine technique and specifically relates to it is a die casting machine oil cooler leak hunting device.
Background
The oil cooler of the die casting machine is divided into two spaces by a copper pipe, water is led into the copper pipe, hydraulic oil is led out of the copper pipe, and the oil temperature is reduced through the flowing of the water. If the oil cooler leaks, hydraulic oil enters one side of water to pollute the whole cooling water system; meanwhile, water can enter hydraulic oil to deteriorate the oil, so that the service life of equipment is influenced.
The oil cooler of the prior die casting machine utilizes compressed air to detect leakage, and the pressure of the compressed air (the air pressure of the compressed air is 0.5MPa) is small, so that the oil cooler cannot be detected under the condition of small leakage amount, and the detection accuracy is low, thereby influencing the maintenance progress of equipment.
Thus, the prior art is subject to improvements and improvements.
SUMMERY OF THE UTILITY MODEL
To the weak point that exists among the prior art, the utility model aims at providing a die casting machine oil cooler leak hunting device that detects the correct rate height.
In order to achieve the above purpose, the utility model adopts the technical proposal that:
the utility model provides a die casting machine oil cooler leak hunting device, includes oil cooler and nitrogen cylinder, the export warp of nitrogen cylinder has the tube coupling relief pressure valve of nitrogen switch, three way connection's input is connected to the relief pressure valve, the manometer is connected to three way connection's an output, and another output passes through the trachea and connects the water inlet of oil cooler, on the oil cooler with the one end of water inlet syntropy is equipped with the delivery port, oil cooler upper portion is equipped with oil-out and oil inlet, the oil-out with the interface terminal surface of oil inlet is in on same horizontal plane.
Compared with the prior art, the utility model has the advantages that:
1. the structure is simple, local materials can be used, and the cost is low;
2. the detection accuracy is high, and the practicability is strong.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The reference numbers in the figures are respectively: (1) the oil cooler comprises an oil cooler, (2) a nitrogen cylinder, (3) a nitrogen switch, (4) a pressure reducing valve, (5) a pressure gauge, (6) a water inlet, (7) a water outlet, (8) an oil outlet and (9) an oil inlet.
Detailed Description
The invention will be described in further detail with reference to the accompanying drawings:
please refer to fig. 1, the utility model relates to a die casting machine oil cooler leak hunting device, including oil cooler 1 and nitrogen cylinder 2, the export of nitrogen cylinder 2 is through the tube coupling relief pressure valve 4 that has nitrogen switch 3, three way connection's input is connected to relief pressure valve 4, manometer 5 is connected to three way connection's an output, and another output passes through the trachea and connects oil cooler 1's water inlet 6, oil cooler 1 go up with the one end of 6 syntropies of water inlet is equipped with delivery port 7, 1 upper portion of oil cooler is equipped with oil-out 8 and oil inlet 9, the oil-out with the interface terminal surface of oil inlet is in on the same horizontal plane.
The utility model discloses a leak hunting method, including following step:
firstly, a water outlet 7 of the oil cooler is sealed;
secondly, filling the oil cooler 1 with hydraulic oil through the oil inlet 9;
thirdly, opening the nitrogen switch 3 and adjusting the hydraulic valve 4 to enable the pressure gauge 5 to be matched with the working pressure of the oil cooler 1;
and fourthly, observing whether bubbles emerge from the oil outlet 8 and the oil inlet 9 or not, wherein if bubbles emerge, the oil cooler 1 has a leakage phenomenon.
Utilize the utility model discloses an foretell leak hunting method, no matter the oil cooler lets out leakage quantity size, can both effectively accurately detect fast to improve equipment maintenance progress.
To sum up, the utility model discloses an foretell structural design solves the weak point that exists among the prior art, has simple structure, with low costs, the inspection correct rate is high, characteristics such as practicality are strong.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
