The low pressure vat post is squeezeed in : is 45mm
Low pressure vat work pressure : <= 1.6MPa ( 25 - 80MPa ) . 4 - 16MPa measures the pump in the interest of the low pressure huge current
The vat is a few 4
The post stopper stroke , 38mm
Chooses to attempt when being getting near the pump , eperiment pressure that needs ought to <= the rated pressure of pump
Four , main composition together with the rule
This pump is the horizontal four vats balanceds configuration symmetric configuration reciprocal pump . The low pressure vat consising of the electrical machinery and decelerates the box and Gao and catchments utensil and relief valve , and overflows the valve , and the water tank and so on the components , the pump two is as the rule and the composition catchs sight of the sketch map , and native the pump work medium is 5 " emulsion and viscosity are not more than 45mm to the clear water of s of C - 60 2 Oil product of /s . The pump packs the water tank on : Moreover provides four foot wheels , the box is linked together through the coupling electrical machinery against decelerateing . The ratio of velocity is a 1: 28 .
Five , fix together with the use
1 , turning on the box installation :
Turn on box queen , and first of all carefully reads the manual , comprehends and comprehends various demand . Pack that the foot is in turn and the pressure gange
2 , the use means :
( 1 ) emploing the preceding ready :
A and base relate to plus ample lubrication oil inner place the box ( black gear oil SYB1103 62S ) .
B and two sides transmission case accede to the machine oil of 30 ( GB443 64 ) . The oil surface ought to be living a little more than sliing to guide a lower part guide
Ought to without delay patching when emploing allows .
Pluss the entirely spotless work medium inner place the C and water tank , and is living when emploing at all times patchs to allow .
The ought to earlier dropping a hint beforehand in D's and is attempied container imbue with medium in order to cut down the attempt pressure time .
E and enlightening the shutoff 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 : Breathing in to put in order work actes as the state
It is regular , in immediate future closing down the shutoff valve , and may attempt to be getting near work , ( the notes : Clockwise rotation shutoff valve not use too much force is supercharge . On the contrary is getting near in the interest of elucidateing )
( 2 ) the matter is pay attention to when emploing :
A and electrical machinery wiring power source ought to pack the fuse , and the earth lead causes that the work is not only dependable and 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 that the engine causes pump together with is attempied system Guan Duan when puing in order out pressure to attain rated pressure either eperiment pressure . Consumer had better be living outside the pump packs in addition in the system shutoff valve with elucidates the pressure valve , and component s such as pressure gange and so on in order that isolates magnetism and is attempied component s like this causes to attempt to be getting near work more successful .
E and relief valve has shiftted well before can not looking upon ... as the valve overflowing employ relief valve to leave 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 .
I.6MPA. F's and overflows valve pressure is regulateed when in the interest of emploing consumer before leaving the factory according to the actual necessaries may to regulate to overflow , and valve is low yet can only do proper accent , and must not be more than 1.6MPa's ( technical personnel who ought to possess appropriate experience manipulates ) .
G and in case by attempt yet utensil volume when very little shall overflow that valve pressure accent is low , merely dos now through the high-handed vat . Yet shall much be attempied the container parallel connection to attempt to be getting near when against tests pressure yet being more than 1.6MPa
Six , remove the means therefore ordinary block reaching
Therefore ( is attempied the component , therefore the divulgences such as Guan Lu's system and so on ) block , recheck pump band block ought to be first of all remove outside the pump like the discovery block in attempting to be getting near
The L and pressure of pump move upward very much slowly either do not move upward .
( 1 ) shutoff valve not Guan Yan : It is taut either changs copper globe , revision valve string
( 2 ) filters the net blocks up either joins the seepage : Wash except for the filth matter , and screws by the taut screw .
( 3 ) post is squeezeed in sealing airtight the packing to injure : Replace sealing airtight packing ..
( 4 ) moving forward and the valve appearing above water to place to be dead either does not seal airtight : Puling down the divination examines that valve pedestal steel globe washes on the revision valve pedestal valve string either replacement steel globe
2 , grit pressure moves upward ununiformly , and the use is heared to fathom every vat to put in order out to reach being getting near out the situation . Therefore decide the reason that obstructs .
( 1 ) possess that the vat moves forward and the valve appearing above water to place to be dead either closely harmful , and consults and follow 1 ( 4 ) to resolve .
( 2 ) there is the vat to move forward and valve breakdown and replacement valve pedestal steel globe either revision valve string appears above water .
3 , pump guarantor's pressure time very much brief either can not attain reachs rated pressure :
( 1 ) the shutoff valve seepage : Guan Jin shutoff valve either chaning the steel globe amends the valve string
( 2 ) the relief valve seepage : The reed is getting near in the regulation , and the valve washing vanishing either pestles the rush pith surface of a cone valve string , and dense to cause shuts .
( 3 ) voltage regulation valve either the low pressure one-way valve seepage : Replace the valve rush pith valve pedestal either amends the valve string
( 4 ) the connector part seepage : Screw by the taut connector .
3 , decelerateing , box temperature rise is very much tall ;
( 1 ) lubrication oil viscosity lets drop either very much filthy : Replace lubrication oil
( 2 ) the endless screw is poored contact against the worm wheel , change of position either the biting feather : The maintenance ought to be moved forward .
( 3 ) the relief valve movement is not ineffective either the pump burden is very much weighty : The maintenance relief valve is guarded against the overload operation .
4 , the electrical machinery burden overload .
( 1 ) the valve movement pressure overflowing very much tall ( overtakees 1.6 with MPA ) : Shiftting lets drop pressure
( 2 ) lubricate harmfully every shere : Replenishment either replaces every box lubrication oil
( 3 ) the supply voltage lets drop very much : Lift supply voltage
( 4 ) low pressure vat post Song Saiguo is taut : Looseing suitably is getting near taut shail suit
Seven , protection and keeping in good repair
L and outward face of machinery have to maintain clean .
2 , water tank is living to plus before the medium rinse neat and tidy not to permit to keep the filth odds and ends .
3 , fresh pump first time the person who employs the gear oil looks upon situation ought to per 30 hours replace . After two times trades may prolong one by one behind the oil time till 500 hours trades oil . Else ought to replace afterwards 56 hours place lubrication oil work , and prolong one by one till 500 hours afterwards .
4 , over a long period of time cease to employ the pump . The rust-resistant handle ought to be carried on in such inside . The external spare parts do not there is not to apply painting the components to apply slushing oil .
5 , constantly pays attention to pump worm wheel and endless screw pair the axial gap , O.05-O.10mm the gap of endless screw is not in the interest of 0.04-0.07mm worm wheel in the interest of in case accordding with this value , and may regulate the screw and regulate the endless screw gap by means of the endless screw , the cushion be regulateed the worm wheel gap in the way of paper .
6 , being living the environment temperature below use work medium of 0 degree in the interest of when water , ought to increase the anticreaming agent , the proposal adopts the denatured alcohol in the interest of the anticreaming agent , and matchs somebody with somebody for instance playing the form

Environment temperature 90% denatured alcohol % Clear water %
O-10 33 67
-10-20 45 55
-20-30 54 46
-30-40 70 30

Eight , the topping-up means
Decelerateing when lubricateing inner place the box , and pulls down the oil level gas release bolt second earlier , in immediate future again through lubricates lubrication oil is emptyed into in the opening , pluss till the oil level ari-bleed hole possess oil to spill over , and screws the bolt passablely .
