Most scientific piston pumps are double or triple-pump. When the piston moves backward, water is drawn into the sealed chamber through the inlet valve.
When the piston continues to move forward, it forces water through the inlet and outlet valves to flow into the pump's inlet and outlet. Triple-pump pumps are a popular design choice for
Laser Welding Machine applications because they produce a more stable flow.
High-speed pumps can produce minimal pressure drop and have lower starting torque requirements.
Double-piston pumps place higher and more stringent demands on system components and operators. YAG Laser Jewelry Welder can directly cause rapid failure, reduced suction volume, and sometimes produce excessive noise and potential damage.
90% of common problems with YAG Laser Jewelry Welder are not typically caused by the pump. Insufficient water flow capacity within the pump is the primary cause of premature failure.
Common failures are caused by damaged materials or components (such as nozzle seals), or an inadequate inlet pipe that fails to allow sufficient water to enter the pump, leading to cavitation. Cavitation causes the gas environment mixed in the water to produce a small explosion, resulting in overpressure damage, and the surface quality of the piston material is seriously damaged.
