Shandong Hairui Zhonglian Pump Industry Co. , ltd. The fire pump that is a major produces manufacturer. When type selecting of client fire pump, manufacturer of my company water pump can provide the before-sales service such as price of fire pump model, fire pump, in order to offer client reference, and manufacturer of my water pump can provide the service of product of custom-built pump industry for the client. This product information is about fire pump common breakdown diagnoses reach maintenance knowledge:

Normally fire pump is in overhaul process, the diagnosis of breakdown is a crucial link, a few kinds of common breakdown give out to reach under eliminate step, for everybody ground of have a definite object in view undertakes the diagnosis of fire pump breakdown:
1, offer without the liquid, supply liquid is not worth or pressure is not worth
1) fire pump does not have affusion or do not have proper exhaust
Eliminate step: Examination pump case and entrance cop are all flood liquid.
2) rate is too low
Eliminate step: The wiring that checks electric machinery is correct, voltage is normal or the vapour pressure of turbine is normal.
3) systematic peak of flow is too high
Eliminate step: The head that examines a system (grind especially loss) .
4) suck Cheng Taigao
Eliminate step: Check existing only pressure head
5) impeller or cop suffer
Eliminate step: The examination has trouble-free content.
6) rotational way is wrong
Eliminate step: Examine rotational way.
7) generation air or entrance cop have leak
Eliminate step: Examination entrance cop has the acupuncture point that do not have gas and / or air leak.
8) the filling in filling case or sealed wear away, in making air leakage enters pump case
Eliminate step: Check filling or sealed change by need, it is normal that the examination lubricates.
9) smoke those who send heat or inspiratory head is insufficient when volatile liquid
Eliminate step: Increase inspiratory peak of flow, seek advice to manufacturer.
10) bottom a powerful person is too young
Eliminate step: Install the heart valve of true measure.
11) heart valve or deepness of entrance canal immersion are insufficient
Eliminate step: Seek advice from correct immersion deepness to manufacturer. Remove vortex flow with fender.
12) impeller gap is too big
Eliminate step: Examination clearance is correct.
13) impeller attaint
Eliminate step: Check impeller, undertake changing by the requirement.
14) impeller diameter is too small
Eliminate step: Seek advice from correct impeller diameter to manufacturer.
15) pressure expresses malposition truly
Eliminate step: Examination place is proper, the examination exports nozzle or conduit.
2, Fire pumpMove a little while to stop machine
1) suck Cheng Taigao
Eliminate step: Check existing only pressure head
2) impeller or cop suffer
Eliminate step: The examination has trouble-free content.
3) generation air or entrance cop have leak
Eliminate step: Examination entrance cop has the acupuncture point that do not have gas and / or air leak.
4) the filling in filling case or sealed wear away, in making air leakage enters pump case
Eliminate step: Check filling or sealed change by need. It is normal that the examination lubricates.
5) smoke those who send heat or inspiratory head is insufficient when volatile liquid
Eliminate step: Increase inspiratory peak of flow, seek advice to manufacturer.
6) heart valve or deepness of entrance canal immersion are insufficient
Eliminate step: Seek advice from correct immersion deepness to manufacturer, remove vortex flow with fender.
7) attaint of gaskets of fire pump carapace
Eliminate step: Examine the case of gaskets and undertake changing by the requirement.
3, fire pump power is used up too big
1) rotational way is wrong
Eliminate step: Examine rotational way.
2) impeller attaint
Eliminate step: Check impeller, undertake changing by the requirement.
3) rotational component is bitten dead
Eliminate step: Examination interior wears away the clearance of the component is normal.
4) the axis bends
Eliminate step: Alignment axis or undertake changing by the requirement.
5) rate is too high
Eliminate step: The winding voltage that checks electric machinery or the vapour pressure that carry turbine.
6) head under rating. Smoke send a liquid too much
Eliminate step: Seek advice to manufacturer. Install throttle, cut impeller.
7) liquid overweight predicts a cost
Eliminate step: Check specific gravity and viscosity.
8) filling case does not have correct filling
Eliminate step: Check filling, new load filling cases.
9) bearing is lubricant incorrect or bearing wears away
Eliminate step: Check and undertake changing by the requirement.
Power is used up big
1) rotational way is wrong
Eliminate step: Examine rotational way.
2) impeller attaint
Eliminate step: Check impeller, undertake changing by the requirement.
3) rotational component is bitten dead
Eliminate step: Examination interior wears away the clearance of the component is normal.
4) the axis bends
Eliminate step: Alignment axis or undertake changing by the requirement.
5) rate is too high
Eliminate step: The winding voltage that checks electric machinery or the vapour pressure that carry turbine.
6) head under rating. Smoke send a liquid too much
Eliminate step: Seek advice to manufacturer. Install throttle, cut impeller.
7) liquid overweight predicts a cost
Eliminate step: Check specific gravity and viscosity.
8) filling case does not have correct filling (filling is insufficient, be entered without right stuff or run close, filling is too close)
Eliminate step: Check filling, new load filling cases.
9) bearing is lubricant incorrect or bearing wears away
Eliminate step: Check and undertake changing by the requirement.
10) the moving clearance between wear-resisting annulus is incorrect
Eliminate step: Examination clearance is correct. Change by the requirement water pump carapace and / or the wear-resisting annulus of impeller.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is about fire pump common breakdown is diagnosed reach maintenance introduction, still think to this problem like you deep one pace understanding, or the problem that has price of model of type selecting of product of other pump industry, water pump, water pump, water pump needs to solve, contact this water pump manufacturer please, my company returns production to suck pump oneself, welcome you at any time seek advice.
