Slurry adopt new technologies impeller

This method is simple, continuous flow , can be at a maximum flow rate and adjustable between zero and no additional investment , for occasions is very wide. Disadvantage is that it relies on changes in hydraulic losses at the valves to be adjusted , thus increasing the hydraulic loss , resulting in mechanical efficiency .
At present, the use of fluid mechanics, by changing the number of impeller blades and blade angle , to change the pump characteristics . 

Such impeller has been successfully tested in my unit . This method is advantageous in that the adjustment parameters to meet the requirements of the situation , there is an obvious energy saving , unit efficiency characteristics. The disadvantage is that the impeller non- styling products , repeated testing is required after installation disassembly , resulting in a greater workload.
For the current centrifugal regulation Either way , should the pump energy consumption, efficiency and other close contacts in the actual work should consider the various factors between the two integrated flow regulation the best way to find the best way for the enterprise , methods .

Impeller inlet and outlet pipe clogged , clean the impeller or piping ; seal ring, impeller badly worn , replace the damaged seal ring or impeller ; shaft speed is less than the specified value, the pump speed should be adjusted to a predetermined value ; foot valve check valve opening degree is not enough or blockage , you should open the backing valve or check valve stop cleaning ; suction pipe submerged deep enough so that the pump suction air , the suction pipe submerged ; suction tube leak, to trap ; filler leakage, eliminate leaks ; sealing ring wear , should be replaced with new sealing ring or the impeller car round , and with a thick seal ring ; impeller badly worn , replace the impeller ; excessive water, sand , or filtration facilities should be increased to avoid the boot .
The pump during normal operation , the entire unit should be smooth , the sound should be normal . If the unit has noise or abnormal vibration , it is often a harbinger of pump failure , you should immediately stop inspection , eliminate hidden dangers . 

Vibration of the pump unit is very complex, from the cause of the vibration caused by watching : There are mechanical , hydraulic , electrical and other reasons, from the vibrating mechanism see : the main excitation force is too large, lack of rigidity and resonance , the reason may there are two aspects of mechanical and hydraulic .
Runtime, if the bearing hot, the following aspects should investigation and the reasons and process : insufficient amount of lubricating oil , or oil circulation, the oil level should be reasonable control ; lubricants poor quality, impurities so that the bearing corrosion , abrasion and rotation is not flexible , the replacement lubricants ; bearing wear serious , repair or replacement of bearings ; pumps and motors of different heart , to re-find the center ; bearing inner ring and the shaft journal with too loose or too tight , make the appropriate adjustments ; with belt drive belt too tight, adjust belt tightness ; subjected to axial thrust too , should pay attention to the impeller balance hole dredge .
If the pump is running meter readings appear extraordinary , electrical heating , it is possible to run the pump super power , possible causes : friction rotating parts inside the pump ; pump speed is too high , a reasonable adjustment speed ; transmission fluid specific gravity or viscosity exceeds the design value restrict specific gravity and viscosity ;slurry pump manufacturer packing too tight or stuffing box without water , adjust the tightness ; bearing worn or damaged , replace bearings ; shaft bending or axial offset ; pump is running at high flow deviate from the design point run .
