The B and two sides are slipd the guideing shelf , and pluss 30#'s machine oil , and are living ought to to supplement at all times when emploing .
Pluss the entirely spotless work medium inner place the C and water tank , and be living to supplement at all times when emploing .
Ought to place the most atthe furthest end of air beforehand in D's and is attempied container , imbue with the medium in order to cut down the attempt pressure time .
E and open the button valve before turing round , and attempies to be getting near the pump do the zero load to transport and actes as , and checks the appearance if not particularly noise reaches . In immediate future breathe in that to flatter the work state regular , and closes down the button valve , and may attempt to be getting near the work ( notes : The button valve clockwise rotation handwheel is in the interest of supercharge , on the contrary in the interest of elucidates the pressure .
( 2 ) and in the use pays attention to the matter :
A and electrical machinery wiring power source ought to pack the fuse , and the earth lead causes work not only dependable but also security .
The oil temperature ought to not overtake 80 s in the box to B and decelerates .
Possess the seepage appearance like discovery pump either else place among the C and work , and ought to without delay remove .
D's and serves as pump ought to cease the engine when puing in order out pressure to attain rated pressure either eperiment pressure value . ( consumer had better be living outside the pump to pack the button valve in addition in the system and elucidates component such as pressure valve and pressure gange and so on , in order that isolating the pump and is attempied the component , causes like this to attempt to be getting near work more successful .
The E and the relief valve has been shiftted well before leaving the factory , and consumer must not regulate as one pleases , and the relief valve is regulateed pressure when leaving the factory act as 1.1 -fold of rated pressure .
Six , remove the means therefore ordinary block reaching
Block that therefore the block discover in attempting to be getting near ought to first of all be remove outside the pump ( is attempied the component , therefore Guan Lu systematically await ) , therefore the recheck pump block .
1 , pump pressure moves upward very much slowly either does not move upward :
( 1 ) and button valve not Guan Yan , Guan Jinhuo regulates steel globe and revision valve string .
( 2 ) and filters the net to block up either joins the seepage , and eliminates the filth matter , and screws taut connector
( 3 ) and the post squeezes in sealing airtight the packing to injure , and replaces sealing airtight the packing .
( 4 ) and moves forward and the valve appearing above water is place to be dead either not to be sealed airtight , and pull down down the check valve pedestal steel globe , and washes on the revision valve pedestal valve string either replacement steel globe .
2 , pump pressure moves upward ununiformly , the use is heared to fathom puing in order out the pressure situation of every vat , therefore decides the reason obstructs .
( 1 ) and possess that the vat moves forward and it is either closely harmful that the valve appearing above water is place to be dead , and consults and follow that 1 ( 4 ) item resolves .
( 2 ) and possess that the vat moves forward and appears above water that the valve injures , replacement valve pedestal steel globe either revision valve string .
3 , pump guarantor's pressure time very much brief either can not attain reachs rated pressure .
( 1 ) and the button valve seepage , Guan Jin button valve either chaning the steel globe amends the valve string .
( 2 ) and the voltage regulation valve seepage , replacement valve rush pith valve pedestal either mends the millstone valve string .
( 3 ) and the relief valve seepage and the reed is getting near in the regulation , and washes the valve pedestal either trades the steel globe .
( 4 ) and the connector part seepage , screws by the taut connector .
4 , decelerateing , box temperature rise is very much tall :
( 1 ) and it is either very much filthy that the lubrication oil viscosity lets drop , replacement lubrication oil .
( 2 ) and endless screw together with worm wheel is poored contact , ' change of position either the biting feather , ought to overhaul .
( 3 ) and the relief valve movement is not ineffective either the pump burden is very much weighty , and the maintenance relief valve guards against the overload to be underway .
5 , the electrical machinery burden overload :
Lubricating harmful every shere ( 1 ) and supplementes either replaces lubrication oil .
( 2 ) and the supply voltage lets drop very much , and lifts the supply voltage .
