Pump industry suppliers - The slurry circulating pump starting process

slurry circulating pump starting process:

( 1) Before starting, according to the requirements of technical specification inspection by heart, everything is all right to determine the pump and motor, priming pump, if everything is normal, starting inspection according to the normal method.

( 2) If pump after the start, the electricity flow, but the alarm system, the attendant should alarm interface query whether bright son brand alarm, vice long-term value and shall report alarm system, electric equipment attendant on-site check the power switch and ensemble. If the slurry circulating pump starting up, the attendant should alarm interface to query the photon brand alarm, vice long-term value and shall report alarm system, electric equipment attendant on-site check the power switch and ensemble. Judgement, attendant on-site inspection maintenance posture caused alarm.

( 3) If be starting early warning information maintenance, overtemperature, load position maintained alarm, return to alarm system, on-site inspection pump if everything work properly.

( 4) If be interturn maintenance maintenance and overtemperature black-out posture, need to check the mechanical equipment of slurry circulating pump. Some countermeasures could improve corrosion resistance of slurry water pump corrosion slurry pump is a high content of high pressure polyethylene lining steel structure of the slurry pump, have good wear resistance, because of the high content of high pressure polyethylene lining floor has good wear resistance, corrosion resistance and crack resistance, thus the transmission of flue gas desulfurization system liquid or slurry cavitation erosion sex, has good abrasion resistance and anticorrosive property.

close the slurry circulating pump impeller cavitation, the location of the damage to the key in the pulp and centrifugal impeller inlet along the side and wheels. Breathe in side the weather board and centrifugal impeller cavitation erosion is the result of the typicality of cavitation and erosion damage. In cavitation cavitation erosion rate increase rapidly after the round pit, such as can not be processed in a timely manner will rain board worn, corrosion of the pump turbine shell, lead to serious damage.

adopt the following countermeasures to improve corrosion resistance of slurry pump life.

(1) effective motor selection, work site in 80% ~ 110% of the total flow.

(2) reduce the speed ratio of the slurry circulating pump. Edge of metal material is relatively higher, pump rate reached 27 m/s, the motor can slow down the pulley or reducer, behind which one than the previous project cost is high.

3. Choose the raw material with good wear-resisting corrosion resistance, immediately to carry out the repair can greatly improve the corrosion resistance of slurry pump application cycle time.
