Constructors insert a power plug of the constant pressure pump into a power socket to control the output pressure of the constant pressure pump.
In actual work, the experimental flow of the proppant performance test system is as follows:
the construction personnel firstly select a certain mass of the ceramsite proppant with the size of 40-70 meshes, the ceramsite proppant with the size of 40-70 meshes is placed in a tray of a balance, the mass of the ceramsite proppant is measured by placing a weight, and the mass is recorded as the original mass. The constructor takes out the piston 3 which is assembled in the proppant containing tank 1 in a sliding way, flatly lays and places a certain mass of 40-70 meshes of ceramsite proppant into a cavity containing the proppant, and then puts back the piston 3. The constructor inserts the power plug of electric heating jacket 4 into supply socket, and the constructor can be at the control panel setting temperature of electric heating jacket 4, and the temperature of electric heating jacket 4 is 90 degrees centigrade.
