Mixed flow pump use and maintenance

Mixed flow pump is the use of impeller rotation generated by the centrifugal force and thrust combined work, oblique flow, also known as diagonal pump, a worm (horizontal) and guide vane (vertical) two.Shanghai Weihu wholesale mixed flow pump manufacturers how to use and maintenance.
(1) bearing the use of thin oil lubrication, should always check and control the bearing body of the oil standard rod between the two marking; bearing grease lubrication, should be regularly replenish the amount of 100 ~ 350HW mixed pump removed the front cover And the back cover to add, the 400 ~ 650HW mixed flow pump can be added through the oil cup.
(2) often check the bearing temperature rise. Generally not higher than the ambient temperature of 40 ℃, the maximum temperature shall not exceed 80 ℃.
(3) Note whether the mixed flow pump running friction and impact, such as mixed flow pump cover and impeller friction, can be mixed in the mixed pump cover and mixed flow between the pump to increase the actual use of gaps 0.3 to 0.7 mm.
(4) the adjustment of the filler must be appropriate, the liquid should be from the packing gland at the drop-like intermittent leakage. Filler is too tight, the shaft will heat and power increase; filler too loose, liquid leakage too much efficiency.
(5) If the motor is connected directly with the mixed flow pump, the axis of the two axes should be on a straight line.
(6) check the inlet pipe with or without leakage phenomenon.
(7) Note whether the power suddenly increased or decreased, whether the flow suddenly reduced, if any, should be excluded.
(8) Always check whether the bolts are loose due to vibration.
(9) in the winter, after the parking should be mixed flow pump and pipeline water discharge.
(10) mixed flow pump for 200 hours or six months after the initial use of lubricating oil (grease). After every 1000 hours or a year after the oil change.
(11) mixed flow pump work 3000 hours or three years after the disintegration of inspection and maintenance.
(12) For long-term suspension of the mixed-flow pump, the operating part should be removed for rust-proof treatment and proper custody.
