If The Adjustment Pressure Of The Internal Control Sequence Valve Is Too High And The Working Pressure Of The Working Hydraulic Cylinder Is Lower Than Its Adjustment Pressure, There May Be Pressure Loss At The Valve Port Of The Sequence Valve, Which Will Cause Temperature Rise And Heat Of The System. At This Point, The Setting Pressure Of The Internal Control Sequence Valve Can Be Reasonably Determined, So That The Working Pressure Of The Working Cylinder Is Higher Than The Opening Pressure Of The Sequence Valve. When The Sequence Valve Works, The Valve Port Will Be Fully Open, With Almost No Pressure Loss At The Valve Port, Thus Avoiding The System Heating Caused By Improper Pressure Setting Of The Sequence Valve.
It Needs To Be Pointed Out That The Motor Frequency Control Technology Of 46m Concrete Pump Vehicle Can Adjust The Speed Of The Actuator By Changing The Frequency Of The Power Supply. In This Way, The Electric Opportunity Of The Pump Vehicle Is Always In A High Efficiency State. Applying Motor Frequency Control Technology To Hydraulic Control System Of Small Aggregate Concrete Pump Can Overcome Some Disadvantages Of Hydraulic System, Such As Simplifying Hydraulic Circuit, Reducing Energy Loss Of Hydraulic System, Expanding Speed Control Range, Improving System Efficiency And Prolonging System Life, Etc.
