Company Profile

The following is a general operation tutorial for diesel engine driven sand pumps:
1. Preparation before startup:
-Check if the diesel engine oil and circulating water tank cooling water meet the specified values.
-Check if the oil in the high-pressure water pump, sand pump, and gearbox is sufficient (all are 40 # diesel oil).
-Add water to the high-pressure water pump.
2. Start the diesel engine:
-Start the high-pressure water pump diesel engine, and at the same time, start the sand pump main engine to idle for a few minutes. After the water temperature and oil temperature gradually increase, close the connecting clutch.
-Gradually increase the diesel engine speed to normal speed (approximately 1450 rpm).
-Close the high-pressure water gun gate valve, open the vacuum master ball valve, and open the vacuum valve.
-Raise the main engine speed of the sand pump to 1300 rpm, lift the sand suction faucet above the water surface, and see a continuous flow of clean water in the sand suction faucet. Place the sand suction faucet back below the water surface, reduce the diesel engine speed to below 1000 rpm, then close the gearbox clutch, and then increase the diesel engine speed to above 1300 rpm and below 1500 rpm (before the new machine enters the running in period, the speed should be controlled below 1350 rpm). After a period of time, a large amount of water flows out at the sand outlet, indicating that the sand suction pump has been filled with water. At this time, close the vacuum valve and the vacuum main valve, open the high-pressure water gun gate valve, and gradually lower the sand suction faucet.
3. Sand pumping operation:
-After the sand pump is filled with water, the sand can be sucked. Pay attention to controlling the sand suction concentration to avoid low concentration affecting equipment production capacity and high concentration blocking the pipeline.
4. Shutdown:
-If the equipment needs to be shut down during operation, the sand suction faucet needs to be raised first.
-After shutdown, check if all components are functioning properly and clean the equipment and surrounding environment.

Please note that relevant safety operating procedures must be strictly followed during the operation process to ensure the safety of personnel and equipment. Meanwhile, depending on the actual situation, it may be necessary to make appropriate adjustments to the operating steps. If you have any questions about the specific operation, it is recommended to refer to the equipment manual or consult a professional.

2. * * Severe water or oil leakage * *: It can affect the normal operation of the equipment and may cause larger problems.
3. * * Pump body overheating * *: Exceeding the normal temperature range may be caused by poor lubrication, overload, etc. Continuing to operate may damage the equipment.
4. * * Diesel engine malfunction * *: such as sudden engine shutdown, abnormal speed, etc.
5. Severe blockage of the sand extraction pipe and inability to clear it: may cause abnormal pressure increase and damage the equipment.
6. * * Transmission component failure * *: such as belt breakage, gear damage, etc., affecting power transmission.
7. * * Abnormal display of current, voltage and other instruments * *: Indicates abnormal working status of the equipment.
8. * * Sudden safety hazards * *: such as fire, smoke, etc.

          A cutter suction dredger is a dredging tool that uses a rotating cutter to loosen the soil on the riverbed or seabed, mixes it with cement to form mud, and then sucks the mud into the pump body through a suction pipe and sends it to the discharge area. It is mainly used for dredging in inland lake areas and coastal ports, suitable for excavating soil such as sand, sandy loam, and silt. During the construction of the cutter suction dredger, the dredging, transportation, and unloading processes can be completed continuously in one go, resulting in high production efficiency.
The main structure of a cutter suction dredger includes the hull, cutter, suction pipe, pump body, and discharge pipe. The cutter is a key component of a cutter suction dredger, usually installed at the bow or side of the ship. By rotating the cutter, the sediment at the bottom of the water is crushed and mixed with water to form mud. The suction pipe is used to suck mud into the pump body, which transports the mud to the discharge area through the discharge pipe.

 
 

The construction process of a cutter suction dredger is generally as follows:
1. Construction preparation: including the formulation of construction plans, survey of construction areas, equipment inspection and commissioning, etc., then positioning the ship and accurately positioning the cutter suction dredger in the construction area. According to the wind and flow conditions, set up the windward and upstream anchors in order to stabilize the ship's hull.
2. Lowering the cutter bridge: Lower the cutter bridge to the designated cutter position for excavation.
3. Soil conveying: The soil crushed by the cutter is transported to the designated mud receiving area through a high-power centrifugal mud pump and a discharge pipeline.
4. Construction monitoring: Real time monitoring of excavation depth, instantaneous water level, cross-sectional view of excavation trench or underwater three-dimensional map and other data to ensure construction quality and safety.
5. Moving ship position: According to construction needs, move the ship to the next construction area by retracting and releasing anchor cables and adjusting the position of the winch.
The specific construction process may be adjusted appropriately based on engineering requirements, soil quality, hydrology, and other factors. topic
