Therefore, if in the case of being connected mulling detecting system without measuring truck or on-the-spot inconvenience with measuring truck, causing site pressure, row
The collection of the technological parameters such as amount, sand ratio there is problems in that 1. for ensureing the flow energy regular supply on fracturing blender truck pipeline and pressure
Splitting car input stability of flow, the operating pressure of fracturing blender truck efferent duct needs between 0.3～0.6Mpa；Pressure parameter essentially from
Pressure gauge, needs operating personnel to continue visual monitoring, and pressure data only has the operating personnel's energy on operating desk in work progress
Seeing, operating personnel requires to adjust according still further to operating personnel, causes coordinating accordingly slowly；2. sand than parameter mainly by operating personnel with
Time regulation sand feeding amount and displacement control, fall within indirectly measurement data, belong to typical empirical data, accuracy is the highest.This
Outward, in addition to pressure parameter, discharge capacity and sand quantify metering accurately than all not having, and the data point reuse in whole work progress needs
In many ways coordinated manipulation controls, and not only adjusts low-response, and directly affects pressing crack construction quality, it is also difficult to defines construction quality and entangle
Confused responsibility.
