1, electro-hydraulic pipe bending (row) machine inspection, testing and maintenance
1.1 Electro-hydraulic pipe bending (row) machine electrical parts should be regularly tested, qualified should be labeled in its shell inspection and test certificates of conformity, before use to check the certificate of conformity in the validity period.
1.2 electro-hydraulic pipe bending (row) machine should be reliably grounded outside the metal. And connected to the leakage protector.
1.3 Electro-hydraulic pipe bending (row) machine should be set up to store and maintain, and often check the hydraulic system oil leakage, oil leakage is found should be dealt with in a timely manner or replace the gasket.
1.4 Electro-hydraulic pipe bending (row) machine should be kept in a clean and dry place, hydraulic piping butt joints should be kept clean to prevent contamination with other grease and debris.
1.5 check the electric hydraulic pipe bending (row) machine force clamp should be free of cracks and deformation, the activities of clamping plate Xiaozi intact and not deformed.
2, electro-hydraulic pipe bending (row) machine use and precautions
2.1 must be processed according to the pipe diameter (or row size) selection of molds, and according to the serial number to the position.
2.2 should first run unloaded, pressurization and pressure relief, observe the hydraulic top bar should be free to expand and contract. No stagnation phenomenon. Confirmation of normal, and then set the mold for operation.
2.3 shall not be pressed between the tube (row) and the mold refueling.
2.4 Clamping machine parts, guide plate support mechanism should be bending pipe (row) in accordance with the direction of timely reversal.
2.5 In the operation of the pressurization process is strictly prohibited personnel stay in front of the top mold.
