Technical characteristics
The unit mixer is intended for preparation of liquid of hydraulic fracturing of layer (ZhGR) with its accumulation in special tanks, and also for preparation of the liquid and sand mix (LSM). The unit is put in action from the car engine through boxes of selection of capacities. The unit is operated with pressure in the technology line to 0,4 MPas, in the hydraulic system — to 32 MPas. On site applications of AS - 40 it is established on the planned condensed platform and fixed by the antiretractable emphasis. At the same time the convenient entrance of tankers with water and oil to the corresponding collectors and peskovoz to the reception bunker of the screw is provided.
Equipment of the AS - 40 unit mixer:
— the equipment of the technology line for preparation of ZhGR and ZhPS, elements of the line are connected by pipelines to locking bodies and instrumentation and automated control systems;
— the equipment of the hydraulic system of the unit which elements are connected by the soaking - up and delivery oil pipelines to the corresponding equipment;
— the control and management system which is turning on sensors, the operator's cabin, devices of life support of the cabin of the operator and also there are auxiliary devices: coolings of the hydraulic system, spark suppression of exhaust gases, raising of the bunker, pressurization and heating of the cabin of the operator.
