How does Huaian Star Hydraulic Technology Co., Ltd. prevent the gear pump filter from desoldering?

For metal mesh filters, when the ambient temperature is high and the local oil temperature at the filter is too high, exceeding or approaching the melting point of the solder, and the original welding is not strong, the impact of the oil will cause desoldering. For example, in the mesh filter at the inlet of the high-pressure plunger pump of the gear pump, it has been found many times that the metal mesh is separated from the frame 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 is 183°C) to silver solder or silver-cadmium solder, whose melting points are greatly increased (235~3000°C).
