How To Prevent The Gear Pump Filter From Being Desoldered?
Parker Gear Pump description: For the metal mesh filter, when the ambient temperature is high, the local oil temperature at the filter is too high, exceeding or approaching the melting point temperature of the solder, and the original welding is not strong, the impact of the oil will cause Desoldering. For example, the mesh filter at the inlet of the high-pressure piston pump of the gear pump has repeatedly found that the metal mesh is separated from the skeleton, and the local oil temperature at the inlet of the plunger pump is very high. At this time, the solder of the metal mesh can be changed from tin-lead solder (melting point of 183 ° C) to silver solder or silver cadmium solder, and their melting points are greatly improved (235 to 3000 C).
