What are the types of sand mixers?
During the entire construction process of the sand mixing truck, the automatic control system is connected to the computer for automatic tracking and fracturing, so that solid additives such as additives, liquid level, density, and pressure from pump sand are discharged. The relevant parameters such as automatic control. The sand mixing truck is composed of four systems: sand density control subsystem, pump sand discharge pressure control subsystem, additive proportion control subsystem, and liquid surface height control subsystem, which are combined into an automatic control system. Each subsystem of the vehicle is composed of relevant parts such as control signal output, parameter comparison and calculation, signal input, and control signal output, etc. All of them are analog signals and pulse signals after passing through various control loops. Processing. The software system of the blender car uses the man-machine conversational Chinese operation, and can set the system parameters according to the fracturing working conditions at the site. After understanding the relevant parameters of the blender, Xiaobian will briefly introduce the two models of the blender.
1. The HS360 model of sand blender is supplied by a number of on-line fracturing units to a more adequate and stable sand fluid. This type of vehicle is also a full hydraulic drive. The entire source of power for the vehicle is supplied from the intake port of the diesel engine and the chassis. The output power of the diesel engine of the vehicle platform is driven by the transfer case to four groups of oil pumps. Four groups of oil pumps are driven one by one to each motor to realize the glue connection, the division and the hydraulic oil fan, sand delivery, and stirring. The lifting of the yarn feeder and the operation of the various parts of the machine are performed. The power of the chassis's engine of the vehicle is connected through the transfer box and the transmission shaft. The transfer box can drive the two groups of oil pumps to drive the oil motors to discharge the pump and enter the operation.
The HCS360 mixed-sand vehicle uses imported heavy-duty chassis, and its off-road performance is relatively strong. It has a large displacement and can meet the needs of high-displacement use of large-sized units in a stand-alone manner. Including the dry Tim automatic control system, automatic sand control system, automatic liquid level control system, liquid Tim automatic control system and the discharge of automatic control system to carry out the relevant process of mixing sand. .
2. HS210 type sand mixing truck is also a type of model used in oil field fracturing construction. It is relatively stable in terms of work performance, and the quantity of mixed sand is also relatively large, and it can be used for several lines. Operation Oilfield fracturing machines provide adequate and stable sand supply. This type of model uses a fully hydraulically driven method. The power is output by the diesel engine of the sand mixing truck. After passing through the transfer box and driving four groups of oil pumps, the six groups of oil pumps are respectively driving the oils to the vehicles. The motor can realize the operation of stirring, glueing, sand feeding, inhaling, adding and the like.
The HSC210 type blender has a relatively large displacement, and the single-unit work can also meet the required displacement of those large-scale units; an automatic control system that can be equipped with multiple items, including a density automatic control system and automatic control at night. The system, liquid level automatic control system, automatic pressure relief control system, and dry addition automatic control system are used to combine the process of sand mixing operations; this model uses full hydraulic drive, and the power of the operating mechanism is driven by the platform. The engine is used for power, and its installed rate is 500HP.
Silent Canopy of Generator Set With the soundproof canopy, noise can be cotrolled. Super sound-absorbing materials and the productions of advanced technology are been selected, ventilation systerm is designed well for its good circulation. Installation of residential-type exhaust muffler can greatly reduce the emissions of the exhaust noise.
Double-door on both sides are designed for maintenance and there is a window for reading the data of controller. Fuel tank at the bottom of the generator set is available.
