The basic principle is that electric hydraulic pump in a closed container, the use of the oil pressure as the working medium to achieve energy conversion and transmission power. Where the liquid is called the working medium, usually mineral oil, such as its role and mechanical transmission belt, chain and gear components are similar. Electric hydraulic pump, the hydraulic cylinder is one of the most simple and relatively complete hydraulic drive system, analyze its working process of hydraulic electric pump company, we can clearly understand the basic principles of hydraulic transmission. Within three months of the new electric pump operation should Note operating conditions, over a period of a new machine running, running health check should take high flow electric hydraulic pump, such as mechanical maintenance, a small two-way screws are loose electric hydraulic pump, if there is no increase in the normal oil, hydraulic oil is deteriorate quickly, check the compliance of conditions and so on. (2) Do not start immediately after the hydraulic pump is applied to the load after starting to be idle for some time without load (about 10 minutes to 30 minutes), especially when the temperature is low, the process is more subject to the warm car, the hydraulic circuit loop plus I normally load and verify operation status. (3) electric hydraulic oil temperature changes observed careful to check the maximum and minimum oil temperature change situation and find out the relationship between the oil temperature and ambient temperature, so that it can know the cooler capacity, storage tank capacity is co-ordinated with the surrounding conditions, conditions of use of the cooling system troubleshooting also have tracked. (4) Note that the new electric pump noise early pump wear less susceptible to bubbles and dust, poor lubrication or overload conditions, etc., will cause adverse effects at high temperatures, so that the pump is making an unusual impact. Display value (5) pay attention to check Keiki class always observe gauge shows the value of the hydraulic circuit, pressure switch signals such as vibration and stability of the situation, the role of early detection of the hydraulic circuit is normal. (6) to observe the mechanical action situation (for modified pump) poorly designed hydraulic circuit or component manufacturing bad, in the initial stage is not easy to find use, so special attention should be under various conditions show the operating state of Nanjing Hydraulic high-volume electric pumps, electric hydraulic pump, hydraulic speed quality provided by the mass-velocity Dezhou City, hydraulic machinery factory. Dezhou City mass-velocity hydraulic machinery plant (www.dzzhisu.com) (www.dzzhisu.com) strong, credible, in Dezhou hydraulic equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improve the quality of innovative ideas will lead you hand speed hydraulic and into the brilliant, for a better future!
