Oil Leakage Treatment Method Of Hydraulic System Of Metal Baler

Metal baling machine adopts hydraulic transmission, compact structure, easy to move, simple operation, easy maintenance, reliable sealing, installation without foot screws. The user can customize the packaging specifications and sizes according to the needs to maximize the cooperation with transportation or storage, which is a good equipment to improve labor efficiency, reduce labor intensity, save manpower and reduce transportation costs.
First, metal baler hydraulic transmission technology
The hydraulic transmission system of metal baler has the advantages of small volume, light weight, large specific power, stable operation, stepless speed regulation, etc., and has been widely used in various cranes. However, the transmission efficiency of the hydraulic transmission system is lower than that of other transmission systems, which is easy to produce faults and difficult to analyze and eliminate. Therefore, maintenance personnel using metal balers are required to have certain basic knowledge of the hydraulic system and be proficient in the working principle and operating procedures of metal balers. However, due to the long-term high-strength use of the equipment, certain failures will inevitably occur, and even affect the normal work of the metal baler. Therefore, it is necessary to know how to deal with the failure of the hydraulic system.
Two, metal baler hydraulic system leakage treatment
The leakage of the hydraulic system of the metal baler affects the safety of the system work, resulting in oil waste, pollution of the surrounding environment, increasing the downtime of the machine, reducing productivity, increasing production costs and contaminating the product, therefore, we must control the leakage of the hydraulic system. So what are the reasons for the leakage of the hydraulic system of the metal baler?
1, metal baler hydraulic system leakage reasons
(1) Shock and vibration caused by loose pipe joints;
(2) the dynamic seals and matching parts wear each other;
(3) The oil temperature is too high and the rubber seal is incompatible with the hydraulic oil and deteriorates.
2, metal baler hydraulic system leakage treatment method
When the stiffness of the metal baler parts or the pre-tightening force of the bolts is not large enough, the mating surface will be separated under the action of oil pressure, causing gaps or increasing the gaps that may exist from the beginning because the sealing surface is not flat enough. With the movement of the matching surface, the static seal becomes a dynamic seal. Rough mating surfaces will wear seals, and changing clearances will erode seal edges.
In order to obtain the initial seal of the metal baler and prevent the seal from being extruded and worn, the installation surface should be flat, the sealing surface should be finished, the surface roughness should reach 0.8μm, and the flatness should reach 0.01/100mm. There should be no radial scratches on the surface, and the preload of the connecting screws should be large enough to prevent the surface from separating.
