In figure: 1, a liquid adds pump; 2, No. two liquid add pump; 3, transition tank; 4, crosslinking agent pond; 5, fracturing blender truck manifold; 6, screen pack one; 7, screen pack two; 8, valve A; 9, valve B; 10, valve C; 11, valve D; 12, flowmeter.
Detailed description of the invention
Embodiment 1:
A kind of mechanism that controls as shown in Figure 1 crosslinking agent, in figure, arrow represents that crosslinking agent flows to, comprise that the liquid connecting by pipeline successively adds pump 1, transition tank 3, No. two liquid add pump 2, also comprise that being arranged at liquid adds the screen pack 1 of pump 1 liquid outlet and be arranged at liquid the screen pack 27 that adds pump 1 liquid inlet, can carry out multiple times of filtration to crosslinking agent like this stops impurity to enter crosslinking agent to greatest extent, ensure the clean of crosslinking agent, and screen pack can dismantle very easily and change and clean, do not affect the normal use of system.
The mechanism of above-mentioned control crosslinking agent, is arranged in addition No. two liquid and adds pump three port A of 2 first outlets and be arranged at No. two liquid and add three port B of pump 2 second outlets; Two outlets of above-mentioned three port A: one is connected with transition tank 3 by pipeline, and centre is provided with valve A8, can add No. two liquid like this crosslinking agent that pump 2 exports and be back in excessive tank; One as discard solution discharge port A, is provided with valve D11.
The mechanism of above-mentioned control crosslinking agent, also comprises fracturing blender truck manifold 5, and two of described three port B one of outlet are connected with fracturing blender truck manifold 5 by pipeline, and centre is provided with valve B9, and one as discard solution discharge port B, is provided with valve C10; In order to ensure the supply of crosslinking agent continually, and output crosslinking agent that can be stable, it is gear pump that an above-mentioned liquid adds pump 1, its range is 1-150L/min, it is plunger displacement pumps that No. two liquid add pump 2, range is 1-50L/min, and the range ability that liquid adds pump is greater than No. two liquid adds pump 2 and can guarantee there is all the time crosslinking agent supply in excessive tank 3, and guaranteeing that No. two liquid add pump 2 can the stable output of continuous operation crosslinking agent.
The valve that above-mentioned valve A8, valve B9, valve C10, valve D11 all adopt alkali resistance material to make, this is to consider the corrosion of crosslinking agent to equipment, reduce replacing and maintenance to valve, make the system works performance of this control crosslinking agent more reliable, very necessary for increasing work efficiency. Described alkali resistance material is stainless steel or copper.
In sum, the mechanism of this control crosslinking agent, can realize crosslinking agent and enter after liquid adds system and be repeatedly filtered, and stops impurity to enter, and can Rapid Cleaning filter screen, can not affect the interpolation of crosslinking agent midway; In addition, can make No. two liquid add pump always in stablizing the duty of discharge capacity by reflux pipeline, also widen the discharge capacity scope that crosslinking agent enters fracturing blender truck manifold, from zero to No. two liquid adds pump peak work capacity, the discharge capacity that can ensure like this crosslinking agent is stable, conveniently precisely controls.
Embodiment 2:
Crosslinking agent is, after mixing by ground surface crosslinking agent pond 5 and additive, to utilize a liquid to add pump 1 and pump in the transition tank 3 on mulling ride, and then No. two liquid add pump 2 and pump in fracturing blender truck manifold 5 from transition tank 3, realize liquid crosslinked. In the time of the less crosslinking agent discharge capacity of needs, No. two liquid adds pump 2 in stable tick-over state, regulate required crosslinked discharge capacity by valve A8, valve B9, and can realize from zero to pump peak work capacity, widened the working range of crosslinking agent pumpage and realized precisely and controlling.
According to required crosslinking agent displacement size, first a liquid adds pump 1 crosslinking agent transition tank 3 is full of, open No. two liquid and add pump 2, allow No. two liquid add pump 2 within the most stable working range, valve valve C10, valve D11 is all the time in closed condition, by valve B9 in full-gear, allowing liquid enter fracturing blender truck manifold 5 through flowmeter, to carry out liquid crosslinked, allow department's liquid backflow in transition tank by control valve A8 switch size, thereby reach required crosslinking agent discharge capacity, such No. two liquid add pump 2 in steady-working state, control crosslinked size by control valve B9, can precisely control, and crosslinking agent is through multiple times of filtration, can be because there not being impurity to block the fuse of flowmeter 12, so just reach the object that crosslinking agent discharge capacity can precisely be controlled, after construction finishes, open valve C10, valve D11, easy cleaning filter screen.
More than exemplifying is only to illustrate of the present invention, does not form the restriction to protection scope of the present invention, within the every and same or analogous design of the present invention all belongs to protection scope of the present invention.
