Looking at the New Industry Opportunities Behind Heavy Duty Sewage Pump

Although summer is about to pass, the threat of high temperature still exists. The slurry pump may also be affected by high temperature during use, which will affect its working efficiency in the long run.If the ambient temperature is too high, we must adjust the machine in time.So when we encounter this situation, how should we operate the machine to keep it running normally without problems?How should it handle itself in a high-temperature working environment?　　1. Slow down the aging speed of the main insulated motor, extend its service life, and be more resistant to high temperatures.2. After adjusting the voltage of the slurry pump, the operating current of the diaphragm pump is reduced to 210a, and the heat value is relatively reduced, thereby reducing the temperature.3. Try to balance the load distribution of the two busbars as much as possible to prevent excessive voltage drop due to overloading of one busbar.4. The pump body has high speed, high air pressure, and large air volume, which greatly enhances the heat dissipation effect.Under the same ambient temperature and load current, the main temperature of the motor dropped by 12℃, and it did not exceed the standard in summer.5. The axial flow fan can be manually controlled.After the main motor is shut down, the axial flow fan can still be operated to cool the motor.If the slurry pump wants to work normally at high temperatures, then the mechanical equipment can be adjusted in time according to the above method to reduce the temperature of the pump body itself, so that it can operate better and extend the service life of the equipment.

Sewage pumps are widely used and have strong sewage discharge capabilities, so they are being paid more and more attention, but we must pay attention to these six points during use and maintenance, otherwise it will cause failure.1. The motor rotation direction is incorrect. Before use, please make sure the motor rotation direction is correct.Although reverse rotation will produce water, the water outlet is small and the flow is large. Long-term reverse rotation will cause irreversible damage to the motor windings.2. No leakage protector is installed. Leakage protector is also called a lifesaver. When the leakage value of the pump is greater than the operating current value of the leakage protector, the leakage protector will cut off the power of the submersible pump to ensure equipment safety and personal safety and avoid unnecessary waste of power.　　3. Turn on when the power supply is abnormal. The difference between the power supply voltage and the rated voltage should not exceed 10%.If the voltage is too high or too low, the temperature of the pump will rise.Turning on the power supply when the power is abnormal will shorten the service life and even burn the sewage pump.4. Long-term dehydration operation of sewage pump. This pump uses water as a cooling source. Long-term dehydration may cause the motor to overheat and combustion.5. Frequently turn on and off. Frequently start the pump will affect its service life.When stopped, a reflux will occur.If turned on immediately, the motor load will start, causing the starting current to be too high and burn the winding.6. Maintenance is usually not carried out.If the sewage pump is discontinuously placed in water, it will rust and cause it to fail to start.When not in use for a long time, do not soak in water for a long time. It should be placed in clean water and run for a few minutes to clean the mud inside and outside the pump.

　　The desulfurization pump is a single-stage single-suction horizontal centrifugal pump, mainly used in the absorption tower circulation pump in the wet FGD device. It has the characteristics of corrosion resistance, wear resistance, deformation resistance and diverse functions.

Transportation of corrosive liquids and coal slurry in coal carbon industry and coal chemical industry; washing and preparing coal distribution pumps.

Overheating of horizontal slurry pump bearings is a common problem, which may be caused by many factors. The following is an analysis of the causes of overheating of horizontal slurry pump bearings and corresponding preventive measures: Cause analysis 1. Cooling system problems: The cold water is not turned on or the cooling water tank is blocked, resulting in poor cooling effect. 2. Lubrication problems: Excessive or too little lubricating oil affects the lubrication effect. The lubricating oil is not clean and contains impurities, which increases friction. Poor or deteriorated oil reduces lubrication performance. 3. Bearing installation and wear: Incorrect bearing installation or improper clearance. Severe bearing wear affects running stability. 4. Shaft and transmission device problems: The shaft is bent and deformed, resulting in uneven bearing force. The transmission device is poorly aligned, and the pump and prime mover shafts are not on the same axis. 5. Other factors: The bearing outlet is blocked and hot air cannot be discharged. Problems with the sealing part, such as excessive water leakage and rapid wear of the packing. The temperature of the pumped medium is too high. The oil pressure is not enough during forced lubrication. Preventive measures 1. Ensure the normal operation of the cooling system: When the slurry pump is working, ensure that the cold water or cooling water tank is open normally. Regularly check whether the cooling water tank is blocked and clean it in time. 2. Optimize lubrication conditions: Adjust the oil volume according to the instructions to ensure the appropriate amount of lubricating oil. Use clean and good quality lubricating oil and replace it regularly. Regularly check the cleanliness and quality of the lubricating oil. 3. Correctly install and replace bearings: Correctly install bearings according to standards and adjust the appropriate clearance. Regularly check the wear of bearings and replace severely worn bearings in time. 4. Correct the shaft and transmission device: Regularly check the bending and deformation of the shaft, and straighten or replace the pump shaft in time. Realign the transmission device to ensure that the pump and prime mover shafts are on the same axis. 5. Other preventive measures: Regularly check whether the bearing outlet is blocked and clean it in time. Check whether the packing gland of the sealing part is too tight or too loose, and whether the packing is deteriorated or severely worn. Control the temperature of the pumped medium to avoid it being too high. In the forced lubrication system, ensure that the oil pressure is sufficient. There are many reasons for the overheating of the horizontal slurry pump bearing, which requires comprehensive analysis and prevention from multiple aspects such as cooling system, lubrication conditions, bearing installation and wear, shaft and transmission device, and other factors. By taking the above preventive measures, the risk of bearing overheating can be effectively reduced and the normal operation of the slurry pump can be ensured.
