Key points in the study of electro hydraulic system.
Domestic central feeding system of electro-hydraulic control skills all use electro-hydraulic share skills, the skill is characterized with three pass share control speed control valve. Although the share of the electric hydraulic technology can greatly reduce the number of components, but because of the use of quantitative pump oil supply, there is always a flow of energy loss associated with the process of work, has been rarely used abroad.
The central feeding system is usually divided into several skills during the process of locking, plasticizing, injection, packing, cooling, mold, pressure and flow during the various needs of different. The pump motor, the load status of feeding process is changing, in the hydraulic system of quantitative pump, pump motor to supply stable speed and stable flow, the hydraulic oil remaining after the overflow valve reflux, this process is called high savings. According to statistics, the energy loss caused by the formation of high pressure up to 36% ~ 68%.
In view of the above valve controlled electro-hydraulic system is the lack of a large loss of energy, to further reduce the energy consumption and reduce noise, the plastic machinery manufacturers to reduce production costs through energy saving to satisfy customer requirements, a variety of energy-saving control skills are researched deeply and widely used, such as Germany, Japan and other countries to carry out the use of servo motor and two kinds of variable pump control system, such as the most basic way of electro-hydraulic control, has been widely used in foreign countries. The current in the central feeding system of energy saving control skills, servo motor with screw pump and variable pump control system of two energy saving, energy-saving effect significantly.
According to the operation principle of such manipulation skills, selection of the central feeding system also has many other advantages of manipulation skills: can reduce the opening and locking impact, extending the service life of the machine and mold; oil service life extension system, reduce repair times, save maintenance cost; lower noise, improved working environment; system oil temperature dropped, can be used more than 30% of water saving and oil cooling; adhere to the control method of the original central feeding system unchanged.
