Mechanical Hydraulic Paver Maintenance

Edit:AKW GROUP   Date:Jun 06, 2017

Modern engineering construction machinery more and more of the use of hydraulic, Mechanical Hydraulic Paver hydraulic technology, especially some large-scale equipment such as paver mechanical and electrical fluid combination, has become the modern engineering construction Machinery Automation degree, engineering quality accuracy important sign. As a mechanized construction enterprise, the technical condition of engineering machinery is good or not, which is important to the normal construction and production of enterprises. Therefore, Mechanical Hydraulic Paver how to maintain the hydraulic and hydrodynamic system is important to improve the equipment integrity, utilization ratio and ensure the quality of the project. In this paper, from the construction machinery hydraulic transmission system maintenance point of view. This paper discusses how to guarantee the safety of the enterprise by transferring the measures to ensure the equipment intact.


Hydraulic transmission technology is permeated into all the modern engineering field, Mechanical Hydraulic Paver and mechanical transmission, power transmission compared to the hydraulic transmission has a unique advantage: (1) in the same volume, the liquid canopy transmission device has more power than the electric device; (2) in the same power, the hydraulic transmission device is small, light weight, compact structure; (3) The quality of the axillary pressure transmission is stable, the mechanical efficiency is high, and has good low-speed load characteristics. Because of the loss of friction loss, the hydraulic transmission system can be most lost, Mechanical Hydraulic Paver the cleanliness of the oil is higher, and the requirements of regular replacement, oil temperature changes will affect the speed of control and noise and other shortcomings. In addition, engineering machinery in the outdoor work often in the mud dust. Frost and snow. The operating load is often changeable and accompanied with vibration, the working speed is often in the transient transition and inertia impact. Therefore, the construction machinery hydraulic system should have special requirements: should have good environment adaptability and reliable sealing: should have higher work reliability and sensitive real-time strain ability, should have better matters dynamic. The system is closed and can be changed.

Because the hydraulic system runs the fault most is because the hydraulic oil pollution and chooses improperly causes, among them to the hydraulic oil choice improper, uses carelessly, is-an important aspect. Therefore, the correct and reasonable selection of hydraulic oil, Mechanical Hydraulic Paver to improve the operation of hydraulic equipment reliability and economy, prolong the service life of the system and components, to ensure the safe operation of equipment is of great significance.


However, the hydraulic oil used by the engineering machinery is mainly anti-wear hydraulic oil. Hydraulic oil is hydraulic transmission oil. Each device from. The designation of the use of oil, this is mainly considered the operating conditions of the system, such as the type of hydraulic pump (gear pump, plunger pump, vane pump), working pressure, temperature, hydraulic components used in the metal, Mechanical Hydraulic Paver the nature of the seals. The reliability of the hydraulic system and the life of the components are closely related to the system of the oil, must not be mixed with the oil of the same brand; In addition, in order to ensure the quality of oil, add or replace oil should be filtered, keep clean. To prevent water or foreign matter into the K hydraulic system to maintain or replace the new hydraulic components, but also pay great attention to cleaning. A simple way to detect the oil of a hydraulic fluid is to drop a drop onto blotting paper, such as a black center in the oil. That means oil dirty, need to change. So make sure that the hydraulic oil has: (1) proper viscosity (2) good viscosity (3) Good oxidation resistance and hydrolytic stability (4) flammability and shear stability (5) and sealing materials environmental compatibility (6) Good abrasion resistance and lubricity (7) Good flammability resistance.
