Hydraulic system design of Multi-angle plastic pressure pipe welding machines
Abstract
Plastic pipe in all sectors of increasingly widespread, especially in PE gas transmission pipelines and water supply and drainage areas with rapid development, demand of plastic pipe welding higher and higher. Fully consider the impact of plastic welding effect of factors , and it is the urgent need to solve the problem of improving the automated welding.
Design point of welding process, using PID control heating temperature in welding PE Gas Pipeline. It is needed to choose the hydraulic system devices with hot-melt welding equipment in accordance with the specific actions, and to the Circuit optimal way combination, Hydraulic devices integrated design. Breakthroughs in the design of the traditional method of packing circuit design, use of one-way valve to control packing purposes, through the electronic control system in the fuel tank of hydraulic circuit in a closed state-pressure pump motor, through the valve to adjust the proportion of Circuit The pressure to ensure that Circuit in the changing pressure, not only to conserve energy and prevent the oil temperature rose too high.
A quality control feature of the design to improve the welding degree of automation is the reliability of the key. Welder for the characteristics of electro-hydraulic control system uses an integrated design, by setting the procedures, the opening stop on the pumps, heating the heating and insulation, packing heat and the time for the intelligent control.
At the same time in the design Circuit valve block, as far as possible ensure that hydraulic transmission efficiency and structure of the compact.
