III. Matters needing attention
(1) Before use, it should be a complete vacuum and then to fill it with water fully to use it to make it have excellent pumping power.
(2) Before installing and use, to pay attention to changing the direction, as the arrow of pump shows, avoiding the parts being destroyed.
(3) While using, if the rubber tube is blocked up by the sand or gravel, it should be dismantled and get rid of them. Don’t operate the machine and pressurize directly to avoid the rubber tube being fractured. Don’t even carry and lift the rubber tube, or else it will sway because of the pressure and hurt the people.
(4) After using it for a while, if the oil or water is found to leak from the base of the machine, you can adjust the screw using both hands according to the anticlockwise direction to make the friction plate in the cover press together with the rubber bowl equipped in the bulgy place of the impeller (use the hand to turn belt wheel, if you meet resistance, it will be suitable). After adjusting, if the oil or water leeks continually, the rubber bowl, the oil seal and the axle sleeve should be changed (if there is friction and it doesn’t go smoothly, it should be grinded to avoid the bearing and the pump base being destroyed)
(5) While installing the rubber bowl, the pipe socket should face the friction plate, if in the contrary direction. The effect of seal is bad. And there should be water in the pump before the machine is operated ,or else, the rubber bowl is easily destroyed without greasing.
(6) In the icing area in the winter, water should be emptied from the pump and oil should be added into the bearing and it should be taken good care of and avoid being rusted.
IV. Common breakdown, causes, ways of getting rid of them:
|
phenomenon
|
cause
|
ways
|
|
I. not pumping water
|
①no full water in the pump
②Bending position of the intake pipe
is higher than the body of the pump
③Water leaks from intake pipe
④Suction lift is too high
⑤Rotate speed is not enough
⑥Rotating direction is wrong
|
① filling water fully
② trying to put the pipe in a lower position than the pump body
③ dismantling the intake pipe first, sealing up both sides of the pipe and to inflating the pipe, putting the pipe into the water and sealing it up.
④ reducing the suction lift
⑤ increasing the rotate speed(using the revolution meter to check it)
⑥ adjusting the rotating direction
|
|
II. After operating for a while, the pipe shakes, some water spouts out from the pipe and then the water becomes less and less and disappears at last.
|
① The air leaks from the intake pipe or the connecting flange( including the sucking pipe is destroyed by the people)
② The bubble in the intake pipe
③ The intake pipe or the impeller is blocked by the grass or the stone(the sound of the machine will tremble at that time)
④ The intake pipe is blocked because it sinks.
|
① finding the leaking place and sealing it or tightening the flange
② trying to get rid of it
③ dismantling the machine and getting rid of the blocked things
④ putting the iron pipe into the sinking rubber tube
|
|
III. the quantity of the sand is small
|
① The intake pipe or the impeller is blocked by the grass or stone
② The rotate speed is not enough
③ The inner part of the pump shows signs of wear and tear or the interval is too wide.
④ The pump lift is too high. The distance of the pipe is too long and too many bending places.
⑤ The horsepower is not enough.
|
① getting rid of the blocked things
② adjusting the rotate speed
③ changing the parts
④ trying to solve it
⑤ increasing the horsepower
|
|
IV. power drain is too much
|
① The rotate speed is too fast.
② The bearing is destroyed.
③ The bearing of the pump is bending.
④ The pump lift is too high.
⑤ The leather belt is tightened.
|
① reducing the rotate speed
② changing the parts
③ straightening it or changing parts
④ lower the pump lift
⑤ relaxing it suitably
|
|
V. The pump has noises and trembles
|
① The bearing is bending and is worn and torn a lot
② The foundation screw is loosed
③The surface of the impeller or the intake pipe is blocked
|
① changing new parts
② tightening
③ trying to get rid of it
|
|
VI. The bearing is hot.
|
① The lubricating oil is not enough or leaks or the bearing is watered.
② The quality of the lubricating oil is low or unclear.
③ The center of the bearing is not put in the right place.
|
① adding enough oil or changing the sealing parts ( rubber bowl or oil seals)
② changing the oil and using the new oil
③ trying to adjust it
|
