Submerged
arc welding plate is one of the most widely used mechanical welding methods in
various industrial sectors, especially in shipbuilding, power generation equipment,
boiler pressure vessels, large pipelines, rolling stock, heavy machinery,
bridges, and oil refining and chemical equipment production. Technology has played a positive role in promoting the development of the welding structure manufacturing industry.
Its working principle is the work piece is placed on the work piece carrier; welding arm with open arc welding torches on gantry frame move horizontally, up and down; so that the welding nozzle head aligning on the welding seam, and then by the gantry shelf moving on the rail as straight line, weld automatically. This machine can weld four welding seam at the same time.

Specifications
How a Diaphragm Pump Works:
1. The pump is driven by an AC or DC motor
2. In front of the motor is a valve assembly containing two to five valve pump chambers. Each valve chamber has a diaphragm behind it in the lower pump housing. As the motor shaft turns, an internal cam positioned behind the diaphragms causes the diaphragms to be pushed forward, then back in a continuous sequence creating a suction. As this suction builds, fluid is pulled through the inlet, through the various valve chamber check valves to the outletÂ
3. The volume of flow is determined by several factors including: the number and size of the pump chambers, cam offset, operating pressure, fluid viscosity
Application:
1. Yacht / RV/Caravan pressurized water systemÂ
2. Sprayer fixtures (Vehicle-mounted sprayers, electric sprayer)
3. Clean machine, Humidifier, Water purification, Medical apparatus Â
4. Food beverage filling & liquid transfer
5. Any other pressurization system
