1. Measures to extend the service life of high-temperature oil pumps: 1. Since the pump body of high-temperature oil pumps operates under high temperatures, a swivel bracket should be installed on the piping during cold-state installation to prevent pipe displacement after heating. 2. The melt filter at the outlet of the high-temperature pump should be replaced regularly; avoid running it under high pressure or at the pressure limit for extended periods. 3. The coupling must be heat-aligned after the pump body has heated up to avoid additional torque during operation. 4. A lockout stop and alarm should be set for the pressure measurement point at the outlet of the high-temperature pump; otherwise, if the discharge pipeline is obstructed, it is prone to cause damage to the pump body.
