Problems solved by technology
[0002] The press is a common equipment in the workshop. The compaction or other operations of the material are completed by pressing down a pressure plate. It is relatively common to realize the drive of the pressure plate by a hydraulic cylinder. The common one is a motor-driven hydraulic pump. In the hydraulic Electric control valves and other components will also be installed on the oil circuit. In some occasions such as external high temperature, due to the existence of electrical components, there is a danger of explosion, so it cannot be used in places with explosion-proof requirements.
