Adjusting of system pressure

 

Note: adjusting work of system pressure done by hydraulic engineer. 

5.1.1

 

System  pressure  is  divided  into  the  system  pressure  of  high  pressure 

and  the  system  pressure  of  low  pressure,  the  adjusting  of  each  of  system 
pressure  is  to  be  done  by  adjusting  the  pressure-regulating  valve  of  relative 
system.  It  has  been  done  well  before  shipment,  no  touch  in  an  ordinary 
situation.  Regulate  value  of  system  pressure  of  high  pressure  is  15MPa. 
Regulate value of system pressure of low pressure is 2.5MPa.If need to adjust, 
do it with reference to below figure.

 

Adjust system pressure 

of high pressure

Adjust system pressure 

of low pressure

Adjust discharge

 

5.1.2

    Adjust system pressure of high pressure: 

a. loose the jam nut of handle of pressure regulating valve; 
b. turn the handle of regulating valve clockwise to increase pressure, turn 

counter clockwise to reduce pressure; 

c. be suspended for a moment on every adjustment of rising by 2 –3 MPa, 

when pressure is stable, go on to adjust; 

d. adjusting to 15 MPa then tightening the jam nut, adjusting is completed. 

5.1.3

    Adjust system pressure of low pressure: First adjust system pressure of 

high  pressure  to  0,  then  in  accordance  with  the  above-mentioned  steps  to 
adjust system pressure of low pressure to 2.5MPa.
