How to improve the running life of hot water submersible pumps

How to improve the running life of hot water submersible pumps
(1), hot water submersible pump population piping should be sealed well, hot water submersible pumps generally have good self-absorption performance, in the course of work, the population pressure to negative pressure, bad seal leading to air into, Resulting in increased noise vibration of the pump, damage to the pump rotor parts, hot water submersible pump life.
    (2), hot water submersible pump at the beginning of the start, no pressure in the export formation, do not blindly speed to prevent shaft or bearing premature damage.
    (3), hot water submersible pump outlet pressure measurement points to set up interlock to stop the alarm, otherwise, once the discharge pipe blocked, easy to cause the pump body is bad.
    (4), for high viscosity hot water submersible pumps, easy to crystal pump, in the system should be set up Tt parking cleaning system, so that after the pump will be easy to clear the pump outside the pump, to prevent the crystallization in the pump, start up.
    (5), cleaning pipetting, do not use hot water submersible pump pump delivery cleaning fluid, should remove the inner parts, after the end of the installation of fluid, so as not to pump inside the stick foreign body.
    (6), for high temperature submersible pumps, because the pump at high temperature operation, the temperature will be shifted after the transfer, so the installation of the cold pipe should be set on the hinge seat, which can effectively prevent the temperature after the pipe displacement.
    (7), for high temperature submersible pumps, couplings must be hot after the pump heat correction, in order to avoid additional torque caused by operation.
    (8), the pump heat medium jacket temperature should be slightly lower than the front and rear jacket tube heat medium temperature. Because the melt viscosity and shear rate into a decreasing function, the gear squeeze, bearing the shear will melt temperature through the pump after the rise of 3 ℃ -5 ℃, reduce the heat medium temperature to prevent melt degradation.
    (9), speed to slow, do not make the sharp rise in pressure before and after, so as not to damage the bearing or make the melt plugging lubrication ring Road.
    (10), hot water submersible pump outlet filter to be replaced regularly, so as not to plug the outlet. The pump long-term operation under high pressure.
    (11), should be replaced regularly. When the hot water submersible pump due to the bearing gap becomes larger and larger when the voice should be replaced. Of course, the bearings can be re-used to re-use the bearing after alloying.
