The hydraulic system provides the power, the motor as the executive component, the hydraulic energy into mechanical energy of the new sand pump. At work, the energy is transferred to the slurry medium through the pump to stir the impeller rotation, so that it produces a certain flow rate, drives the solid flow, and realizes the slurry transportation. The hydraulic motor adopts domestic famous quantitative piston motor and five star motor, which has the characteristics of advanced and reasonable structure, good performance, high efficiency and stable work. According to the actual working conditions of customers, choose different displacement motors.
Compared with the electric submersible cement sand pump, it has the following advantages: 1, Hydraulic transmission movement inertia is small, fast reaction speed, can achieve a wide range of stepless speed regulation; 2, Automatic overload protection, no motor burning phenomenon; 3, The extraction of sand slurry, sediment, slag and other solid concentration is high, can reach more than 70%; 4, Connected to excavators and other machines with hydraulic system, can realize free transition, especially in remote areas of construction, power shortage, the advantage is more obvious; 5, Can be used as an accessory of the excavator, in the adverse digging when extraction and long-distance transportation, improve the value of the excavator itself.
