PW4 PTA Machine – Gasoline Engine Valve Face

Description

Below is the outline of PW4 PTA hardfacing equipment

Equipment Working Range

• Valve head diameter: 16-45mm (Cone Angle 90-150degree)
• Valve stem diameter: 4.5-8.5mm
• Total length: 80-140mm

Welding Parameter

• Arc strike power supply: Panasonic YC200BL, no-load voltage ＞60V, current 0-120A, fluctuation range ±0.1A.
• Transferred arc power supply: SanRex 400P, current 5-250A, fluctuation range ±0.1A.
• Powder feeder: Servo motor, powder feeding quantity 4.5-45 gram/minute，loading volume 15kg
• Welding gun: Made in China equal to STELLITE-MODEL 600, welding current 5-250A, pressure of cooling water should be bigger than 4Kg/cm. Particle size of powder should be -100mesh to +325mesh.
• Cooling water tank: 5000kilocalorie, volume 40L.

Control Panel

• It can set up and display welding parameter(Mitsubishi 10inch touch screen)
• Gas control: It used for digital flow rate control of center gas, powder feeding gas, protective gas.(Japanese island KOFLOC3600)
• It can control working of powder, turntable, welding current, gas automatically and manually.
• It can store every welding parameter (can divide 6 overlaying section), it has failurewarning and reminder.
• Display first three engine valves complete beat time and welding quantity of each working time.
• If separate preset of nozzle, electrode and cooling disc switching frequency reaches 6 figures, the machine will be paused with tri-color indicator lighting.
• Control cabinet use sealing industrial air condition
• Cleaning brush can be rotated. Cleaning frequency can be set.
• Valve gripper use gripping type, positioning surface is inlaid with cemented carbide

Other Components

• Positioning turntable: rotation speed is 1-15RPM, angle resolution is ± 0.1 °, tilt range is 10-90 °. We use Mitsubishi servo motor
• PLC: Mitsubishi FX series
• All servo motor use Mitsubishi
• Tracheal and water-cooled cable assemblies: 5 meters of air, water pipe components for connecting the torch and the ignition box.
• Welding chamber and safety device: The welding chamber is used to isolate the welding area and the operator. When the door of the welding chamber is opened, the welding cannot be carried out in order to protect the operator from being burnt by welding arc. At the same time, the equipment alarm. In addition, no gas and no water can also make an alarm.
• Protection system: impeller flow sensor is set for water flow switch.
• Tri-color indicator that indicates the operating status of the device is installed.
• All tooling that contact work piece should be resistant to wear.
• Equipment mechanical structure assembly drawings, electrical schematics, pneumatic schematic diagram are provided.
• Abnormal shutdown of the equipment shall not be allowed more than once per shift, and each shutdown shall not be allowed for more than 5 minutes.
• Block of material loading and unloading does not allow more than once per shift during automatic process.
• Once set of tools for daily maintenance and disassembly is provided.
• Lighting is installed in work area.
• Pneumatic components is SMC brand.

Installation Requirement

• It requires an 80A three-phase air switch for good grounding protection.
• It requires an oxygen pressure relief valve with a 4Kg/cm2 partial pressure gauge and industrial pure argon with a purity of not less than 99.99%.
• It requires a work space that is large enough for it according to the actual size of the equipment.
• The equipment installation site should be away from other high-frequency sources.
• The workplace should maintain good ventilation and ground dust protection facilities, and the ambient temperature should generally not exceed 35°C.
• There must be no flammable or explosive materials around the workplace.

Equipment Wiring

• The power line should be not less than 10mm² four-wire rubber wire. It adopts three-phase five-wire system, and the zero/ground lines are separated and must be reliably contacted.
• Connect the gas supply to the air intake pipe of the device and tighten the fitting to ensure no leakage.
• Connect the trachea, water pipes and cables among the components of the equipment.
