Corrosion is prohibited in the operation of the centrifugal pump and magnetic pump in idle running, the air freight transfer to pump failure and damage, users in the use process, also often due to error occurred idle, the anticorrosive centrifugal pump magnetic pump and on how long idle time, actually may not be damaged, anticorrosive water pump
idle in a short time will not damage (
Within 1 minute)
Centrifugal pump and idling magnetic pump, the impeller no contact or rarely contact medium, can't effectively work, liquid cannot carry out normally, these are made useless.
Motor of load because of the lack of effective work are very small, and generate an electric current is small, influence won't have any for motor, water pump idling for pump is fatal.
Idle pump cavitation, easily damage to pump body with flow;
Idle form of pump mechanical seal or packing seal form idling, will not get fluid lubrication, lead to dry grinding, quickly damage;
Idling of rotor pump parts, pump experience fever, no liquid cooling with heat bilges cold shrink the role of the narrow gap position (
Such as seal ring)
It is easy to bite dead;
Idling of multistage centrifugal pump balance disc no lubrication, balance disc will soon be burned to death, damage.
Corrosion resistant pump idling reasons: insufficient water pump imported medium or feed water pressure is not enough, or the pump inlet pipe blockage, or the pump chamber air has no rows in the body.
A, corrosion-resistant centrifugal pump magnetic pump before starting to prepare 1.
BoZhuan motor blades with the hand, should be no card grinding impeller, flexible rotation.
Open the inlet valve and open the vent valve to make liquid fills the pump cavity, then close vent valve.
Dish with the hand moving mechanical seal face to make lubricant into the water pump.
Some power motor, determine whether to correct.
Second, start and run.
Fully open inlet valve, close out pipeline valve.
, turning on the power supply when the pump at normal speed, then gradually open the valve on the discharge pipe line, and adjust to the required conditions.
Watch the meter reading, check the shaft seal leakage, normal mechanical seal leakage, & lt;
Three drops/min, check, bearing temperature rise of motor & le;
= 70 C, if found abnormal situation, should be timely treatment.
Three, parking 1.
Gradually closed out pipe valves, cut off power supply.
Close the inlet valve.
Such as environmental temperature is lower than 0 degrees C, you should put all the liquid in the pump, so as to avoid frost crack.
Such as discontinued for a long period of time, will pump disassembly cleaning, packaging. water pump
winter cover pump, as the name suggests, find extensive use in pool cover drain pump institutions. Since winter cover pump has become much dependent on technology in today's world, there is wide use of such water pump.
Exceed customers' expectations in the procedures of manufacturing water pump.
The trend toward using pool cover drain pump water pump to ease winter cover pump, once established, soon extended into such additional fields as pool cover drain pump and winter cover pump.
