Embodiment 1
[0016] a kind of like figure 1 The mechanism for controlling the cross-linking agent shown in the figure, the arrow in the figure indicates the flow direction of the cross-linking agent, including the No. 1 liquid addition pump 1, the transition tank 3, and the No. Filter 1 at the liquid outlet of pump 1 and filter 2 7 at the liquid inlet of No. 1 liquid and pump 1 can filter the cross-linking agent multiple times to prevent impurities from entering the cross-linking agent to the greatest extent and ensure cross-linking. The cleaning of the coupling agent, and the filter screen can be easily disassembled and replaced and cleaned without affecting the normal use of the system.
[0017] The above-mentioned mechanism for controlling the cross-linking agent is also provided with the three-item port A of the first outlet of the No. 2 liquid addition pump 2 and the three-item port B of the second outlet of the No. 2 liquid addition pump 2; two of the above-mentioned three items of p...
Embodiment 2
[0022] After the cross-linking agent is mixed with the additive through the cross-linking agent pool 5 on the ground, it is pumped into the transition tank 3 on the sand mixing platform by the No. 1 liquid addition pump 1, and then the No. 2 liquid addition pump 2 is pumped from the transition tank 3 In the sand mixer manifold 5, liquid cross-linking is realized. When a small cross-linking agent displacement is required, the No. 2 liquid addition pump 2 is in a stable low-speed working state, and the required cross-linking displacement can be adjusted through valve A8 and valve B9, and can realize from zero to the maximum working capacity of the pump. The working range of cross-linking agent pump displacement is widened and precise control is realized.
[0023] According to the required cross-linking agent displacement, firstly, the No. 1 liquid addition pump 1 fills the cross-linking agent transition tank 3, and then turns on the No. 2 liquid addition pump 2, so that the No. ...
