The pump is getting near in the power-driven attempt of DSY
Attempting to be getting near the pump is only feeding the ideal installation that different type of pressure container , piping , valve , boiler , steel vase and fire fighting material obtained high-handed liquid in doing test of hydraulic pressure and the laboratory . Attempting to be getting near the pump produce reaches to form a complete system to attempt to be getting near and to test the project , and has usied the item is stressly opened up in the national defence scientific research in , moreover the application is living the aviation territory attempt pressure eperiment , great in the interest of our country high pressure of scientific research item sbterranean demolishs eperiment and high temperature high pressure tests and deep sea eperiment and room technique special pipe are tested , and wholly make the great contribution

One , the summary

Our mill specially gives birth to power-drivenly , and the hand stirs to attempt to be getting near the pump . This the engine anthology home and abroad same produce strong point is designed and manufactures native engine distinguishing feature ; Boostting , the voltage regulation performance is good , and the noise lets drop , and it is easy to be convenient to manipulate , and service life is elder .

Two , the use

This engine is only feeies different type of pressure container and piping , valve , steam boiler and rubber , and Guan Jian and so on does the pressure quiz , and usablely obtains installation in hydraulic pressure source to the laboratory and so on .

Three , the technique parameter

Ratedly put in order out pressure 2.5MPa
Rated rate of flow 300 L/hs
370W ( 220V and 380v ) is lead to the electrical machinery meritorous service
Whole set weight 20Kg

Four , main composition together with the rule

This engine consists of the reciprocal pump chiefly , the non-return valve , Guan Luji intake appears above water gum runs and so on the components . The composition of pump is catch sight of that sketch map native the pump use medium is near against water oil product such temperature of water either viscosity and act as s of 5 - 60 .

Five , installation together with the use means

L and fix

( 1 ) solidity the rubber cushion scheduled to the pedestal .
( 2 ) join the pressure gange against the pump according to the picture .
( 3 ) gum Guan Yushi shall appearing above water is getting near that piece and the pump joins , and fixs well intakes the tube , pays attention to sealing airtight of every joint part , and have to not there is not the divulgence .

2 , the use means :

( 1 ) emploing preceding ready work :

A ) examines that every whorl joint part has or not to become flexible .
B ) check electrical machinery and line are cut off from , and whether the place accords with the electrical equipment profession and regulate that the whole set have to possess dependable grounding
C ) the one clean water storeing utensil headwaters supply that and the guaranty is enough are put up .

That ( 2 ) operation reaches pays attention to the matter ;

A ) the outlet valve is unfolded , switching on the electrical machinery , the Guan Luzhong air line to the greatest extent afterwards when intakes simply may close down that the outlet valve at this moment pressure simply may move upward one by one .
B ) serves as the pressure liter to close down the power source when eperiment pressure , at this moment pump simply is in voluntarily defending to be getting near the condition .
C ) attempies to be getting near to complete , in immediate future loosens the outlet valve , and may unload except for pressure .
D ) work pressure must not overtake engine and ratedly put in order out pressure ( rated pressure possess the relief valve automatic control , that valve has been regulateed when leaving the factory and till is requireed , consumer oridinarily ought to not regulate as one pleases ) .
E ) strictly forbids to be living to intake Guan Lu can not to intake either not there is not below the headwaters supply situation elder time opens an engine , and native machinist being living as hour cuts off the water supply in the source .

Six , remove the means therefore ordinary block reaching

Therefore like the discovery block in attempting to be getting near , therefore ought to remove outside the pump ( by fathoms is getting near divulgence in piece Guan Lu's system the ) block earlier , therefore the recheck pump block .
1 , the electrical machinery can not switched on : The power source is stopped providing electricity either the line out , and supplys power source , restoration line .

2 , intaking , Guan Luxi does not feed water to a steam engine , such reason and settlement means .
( 1 ) intaking , the tube leaks gas , and the tube are intake in repair either replacement .
( 2 ) intaking , the valve series does not seal airtight , possess impurity to block the stopper , and eliminates impurity , and removes the stem squeezeing in , causes seals airtight . In immediate future the means may be takeed and pull down into the water tube , briskly counts the degree according to stiing into the water valve in the way of the finger , and till hears moves forward water valve time hopping to possess clear " Da " voice passablely , and below detachable intakes the valve series impurity eliminateing .
( 3 ) intaking , the valve lose effectiveness , and pestles the valve series either replacing

3 , pressure is not ascend either rate of flow defect :
( 1 ) filters the net blocks up , and breathes in water happenning the hardship , and eliminates the filth matter , and washes filtering the net .
( 2 ) breathing in to overtop into highly , it is high that fluid is moved forward in the raise .
( 3 ) intaking , the valve lose effectiveness , repair either the replacement valve series .
( 4 ) closely stuff either the packing ring weares and teares , and replaces closely to stuff either the packing ring .
( 5 ) the taut firm nut of piston becomes flexible , taut once more firm .
It is over-dose to let out divulge to ( 6 ) relief valve either flattering the air valve lose effectiveness . Repair either replacement relief valve either the outlet valve valve series .

4 , pressure gange does not there is not pressure displaying :

( 1 ) the hydraulic pressure vat pedestal damping opening is blockked up , and the use carefully silk gos to the odds and ends .
( 2 ) the pressure gange injures , the replacement pressure gange .

5 , ceases behind the engine can not defend being getting near :

( the 1 ) valve series failure is pestle the valve series either replacing .
( 2 ) the outlet valve is closed down not tightly , repair either the replacement outlet valve series .

6 , different connections to reach the sealing airtight part to leak water , seals airtight a breakdown replaces relevantly seals airtight piece .

7 , buzz greatly and shakes intensely : Electrical machinery either native the pump binding bolt becomes flexible , taut once more firm .

Seven , protection and keeping in good repair

1 , ought to examine respectively to connection a fastening piece whether to become flexible in the use process at all times , in case possess becoming flexible ought to taut at once firm .
In immediate future 2 , ought to cease the engine check in case happenning particularly noise in the operation process .
3 , when being living the leader packing puling down unfold electrical machinery wind overspreading , and wind the galvanic electricity engine shaft screwing and is getting near the taut nut , the regulation fitting gap , till easyly winding , Fang Ke's circular telegram trial run .
4 , winter afterwards use ought to reach inner place Guan Lu Yu Shuipai inner place the pump to the greatest extent .
5 , that crew commander stage when ceaseeing emploing , ought to carry on the rust-resistant handle . The means is breathed in pouing once slushing oil either rust-resistant fluid to the greatest extent by Yu Shuipai earlier again .
