When detecting the concrete discharge capacity; Displacement control device is through placing first checkout gear on the pumping equipment; Detect the required very first time length of concrete in the pumping equipment output concrete cylinder; And the capacity of concrete cylinder is known, therefore can determine the pumping equipment interior concrete discharge capacity of length at the appointed time according to the capacity of detected said very first time length and concrete cylinder.If very first time length is Δ T, the capacity of the concrete cylinder of pumping equipment is V, then pumping equipment at the appointed time the concrete discharge capacity in the length be V/ Δ T.If first checkout gear comprises one or two first near switch; Then displacement control device receives first first signal exported during to S valve swinging axle near inductive switching; And, confirm the required very first time length of concrete in the pumping equipment output concrete cylinder according to the time point that receives first signal.Concrete:
When first checkout gear comprises one first during near switch; As shown in Figure 2, it is T1 that displacement control device receives first time point near first signal of switch output, and this moment, pumping equipment was with the output of the concrete in the concrete cylinder 1; The S valve of pumping equipment continues swing; With the output of the concrete in the concrete cylinder 2, it is T2 that displacement control device receives first time point near first signal of switch output next time, and this moment, pumping equipment was again with the output of the concrete in the concrete cylinder 1; That is to say; In the time span between T1 and T2, pumping equipment has been exported two concrete that the concrete cylinder is interior, and the required very first time length of concrete in concrete cylinder of pumping equipment output should be Δ T=(T2-T1)/2 so.
When first checkout gear comprises two first during near switch, as shown in Figure 3, it is T1 that displacement control device receives first time point near first signal of switch 1 output; This moment, pumping equipment was with the output of the concrete in the concrete cylinder 1; The S valve of pumping equipment continues swing, and it is T2 that displacement control device receives first time point near first signal of switch 2 outputs, and this moment, pumping equipment was with the output of the concrete in the concrete cylinder 2; That is to say; In the time span between T1 and T2, pumping equipment has been exported a concrete that the concrete cylinder is interior, and the required very first time length of concrete in concrete cylinder of pumping equipment output should be Δ T=T2-T1 so.
When detecting the accelerating admixture discharge capacity; Displacement control device is through placing second checkout gear on the accelerating admixture pump; Detect the second required time span of accelerating admixture in the accelerating admixture pump output accelerating admixture outlet conduit; And the capacity of accelerating admixture outlet conduit is known, therefore can determine the accelerating admixture pump interior accelerating admixture discharge capacity of length at the appointed time according to the capacity of detected said second time span and accelerating admixture outlet conduit.If second time span is Δ t, the capacity of the accelerating admixture outlet conduit of accelerating admixture pump is v, then the accelerating admixture pump at the appointed time the accelerating admixture discharge capacity in the length be v/ Δ t.

When second checkout gear comprises one second during near switch; As shown in Figure 6, it is t1 that displacement control device receives second time point near the secondary signal of switch output, and receive second time point near the secondary signal of switch output is t2 next time; That is to say; Rotated a teeth groove in the time span of the gear of accelerating admixture pump between t1 and t2, the gear of accelerating admixture pump comprises N teeth groove, and the gear of accelerating admixture pump rotates a circle; The accelerating admixture pump is just with the output of the accelerating admixture in the accelerating admixture outlet conduit, so the second required time span of accelerating admixture in the accelerating admixture pump output accelerating admixture outlet conduit should be Δ t=N (t2-t1).
When second checkout gear comprises two second during near switch; As shown in Figure 7, it is t1 that displacement control device receives second time point near the secondary signal of switch 1 output, and receiving second time point near the secondary signal of switch 2 outputs is t2; That is to say; Rotated teeth groove half in the time span of the gear of accelerating admixture pump between t1 and t2, the gear of accelerating admixture pump comprises N teeth groove, and the gear of accelerating admixture pump rotates a circle; The accelerating admixture pump is just with the output of the accelerating admixture in the accelerating admixture outlet conduit, so the second required time span of accelerating admixture in the accelerating admixture pump output accelerating admixture outlet conduit should be Δ t=2N (t2-t1).
Wherein, Stipulated time length is confirmed according to the unit of the very first time length and second time span; If the unit of very first time length and second time span is minute; Then stipulated time length is 1 minute, if the unit of the very first time length and second time span is second, then stipulated time length is 1 second.
