Specification requirements for wire and cable in installation of pipe fitting equipment

Requirements for installation of pipe fitting equipment + wire and cable: medium frequency power supply installation, from power transformer to medium frequency power supply three-phase wire with 120-300 square mm of insulated wire or four-core cable.The diameter of the connecting wire between the motor control cabinet of the pipe making machine and the motor of the pump station is selected: the three-phase insulated wire of 10-16 square millimeters is selected for the working pump motor.Fast feed pump three-phase wire diameter of 6-10 mm square insulation wire.Three phase conductor of gate pump motor is selected with 4 square millimeter insulated conductor.Electro-hydraulic solenoid directional valve, solenoid relief valve, stroke switch, the connecting wire diameter of the main operation table and the motor control cabinet is 0.75-1 square millimeter insulated wire or core cable.Specifications and requirements for wire and cable for installation of pipe fitting equipment

Repair and maintenance of pipe fitting equipment

First of all, check the fasteners of all parts of the pipe fitting equipment and make them in a tight state.Each joint of the hydraulic pump tension part of the pipe fitting equipment is equipped with oil-resistant rubber ring. If the seal is damaged or leaking oil, it should be replaced in time.If it is found that forward and backward failure, first check whether the solenoid valve action such as the solenoid valve action is normal, and then check whether the sequence valve, relief valve, or one-way unloading valve is stuck by debris phenomenon.This phenomenon is usually prone to occur when pipe fitting equipment begins to be used.If there is a phenomenon of stuck, open it and clean it with diesel oil, then reinstall it.Clean the oil tank and filter the hydraulic oil once within 1 to 2 months after the pipe fitting equipment begins to use.When cleaning the tank, the oil inlet filter of each pump should be cleaned.The above is a brief introduction to the maintenance and protection of pipe fitting equipment. I hope it can help you.
