The regular hydraulic mud pump-excavator dredging pump is a submersible single-stage single-suction centrifugal pump, which is divided into several series and specifications such as 300mm, 250mm, 200mm, 150mm, 100mm, etc. according to the outlet diameter. The flow parts of the hydraulic mud pump are made of high chromium wear-resistant alloy materials. After a large number of tests and industrial field operation tests, the pump is wear-resistant, energy-saving, reliable in operation, high lift, and submersible (can be pumped to a depth of 60 meters) , Large flow (up to 1000 cubic meters per hour for a single pump), wide application range, long conveying distance, etc. The pumped solid-liquid mixed concentration can reach 60, which is suitable for pumping various mud, slag slurry, silt, ore, industrial and mining enterprises to transport slag, tailing slurry, tailings ore, slurry, power fly ash transportation and other highly abrasive media .
   

Main features of hydraulic slurry pump

1. There is a stirring impeller at the bottom of the pump, which can prevent large solid materials from blocking the pump, so that the solid and liquid are fully mixed, which is easier to handle.

2. This pump can handle solid materials with a particle size of 50mm, and the solid-liquid extraction concentration can reach more than 70;

Note: Due to different working conditions, the output of the pump may also vary with the influence of factors such as the processed medium, on-site operation, and transportation distance.

3. This device is mainly installed on the excavator. The power is provided by the hydraulic station of the excavator, which can realize free transition, and the power source is a diesel engine, which can solve the problem of power inconvenience during construction in remote areas.

4. The flow parts are made of hard chromium alloy, which has a long service life. The hydraulic drive of the dredging pump of the excavator has the following advantages:

1) Light weight per unit power, that is, under the condition of the same output power, it is small in size, light in weight, small inertia, compact in structure, and good in dynamic performance.

2) The hydraulic transmission device works smoothly, responds quickly, has little impact, and can quickly start, brake and change directions frequently. It is convenient to realize stepless speed regulation, and the speed regulation range is large.

3) Hydraulic transmission is easy to obtain large force and torque, which can make the transmission structure simple and low failure rate.

4) The control and adjustment of the hydraulic transmission device are relatively simple. It is more convenient, labor-saving, and easy to realize automation.

5) The hydraulic system is easy to achieve overload protection. At the same time, because the oil is used as the transmission medium, the relative moving surfaces can be lubricated by themselves, so the original parts have a long service life. Excavator dredging pump-dredging pump driven by excavator with hydraulic reamer

6) Since the hydraulic components have been standardized and generalized, the design, manufacture and use of the hydraulic system are more convenient. The arrangement of hydraulic components also has greater mobility.

Structural characteristics of excavator slurry pump

1. This pump is equipped with a stirring device, which can stir the sludge deposited on the bottom of the water into a turbulent flow and then extract it, instead of the traditional operation method with high-pressure water gun; excavator sludge pump

2. This pump is mainly composed of volute, impeller, pump seat, pump housing, stirring device, sealing device, motor seat, hydraulic motor, etc. The flow parts are made of high chromium wear-resistant alloy materials, which have a long service life;

The pump is fixed on the hydraulic excavator, and the power source comes from the hydraulic oil source of the excavator, avoiding the problem of having no power supply and additional power.

Precautions for use:

1. Ensure that the hydraulic oil of the system is pure, has less impurities, and has good lubricity, compatibility and stability;

2. According to the pressure, displacement, efficiency, etc. of the existing hydraulic system, a sediment pump should be reasonably equipped to enable the system to operate normally and not to exceed the system load for a long time;

3. When used with the excavator, the arm of the excavator should move lightly and slowly, and it is strictly forbidden to smash or smash it under hard working conditions to avoid damage to the pump body;

4. Select hydraulic oil pipes of standard specifications, use specified bolts and tighten them with torque. Unqualified installation will cause malfunction, damage or oil leakage;

5. When the equipment is transferred, it is necessary to ensure the cleanliness of the hydraulic oil port to prevent the entry of impurities, etc., which will affect the normal service life of the motor;

6. Without permission, it is forbidden to modify or disassemble the equipment without permission, otherwise it will cause abnormal operation or abnormal operation, etc.;
