How to match dredge pump and gearbox-design
The sand dredge pump needs to be equipped with a diesel engine or a motor to provide power for the sand suction operation. It is more economical to use the motor in a convenient working environment, but most of the sand pumping environment is carried out in the field. It is inconvenient to use electricity and can only be equipped with a diesel engine as a power source. When the speed of the diesel engine and the sand suction pump are not equal, the gear box or the pulley is needed to adjust the speed to achieve the purpose of synchronous rotation.
The speed of the sand suction pump is relatively low, generally around 400-900 rpm, especially for large-sized sand suction pumps, the diameter of the impeller is large, and the rotation speed is low. The speed of the diesel engine is relatively high. The diesel engine we supply to the customer is generally a low-speed marine machine, and the rotational speed is generally between 1000-1500 rpm. When a high-speed diesel engine is connected to a low-speed sand suction pump, it needs to be adjusted with a gearbox of the appropriate speed ratio. The gearbox has the following advantages: reliable transmission movement, constant instantaneous transmission ratio; applicable load and speed range; high efficiency, long life, compact structure, small outer dimensions; . When the sand suction pump is matched with the diesel engine, it is necessary to select a gear box of the appropriate speed ratio.
The purpose of the gearbox is to adjust the speed of the sand pump and the associated diesel engine. The power of different types of gearboxes is different from that of diesel engines. Each type of gearbox has its own transmission capacity. The coefficient of transmission capacity of the gearbox is based on the ratio of the power of the diesel engine and the speed of the diesel engine. To determine. The reduction ratio of the gearbox is determined by the ratio between the speed of the sand pump and the speed of the matching diesel engine. For example, the speed of the sand pump is 730 rpm, and the 330 kW diesel engine is equipped with a speed of 1200 rpm. The reduction ratio of the gearbox is 1200/730=1.6; the transmission capacity is 330/1200=0.275. After these two values are determined, you can find the corresponding gearbox model.
In the actual configuration, the diesel engine power of the sand suction dredge pump generally follows the principle of the big horse-drawn car. The power of the configuration is selected to be a diesel engine of a larger specification model, and the power reserves a certain margin. Therefore, the diesel engine generally works at a power of about 80% in actual operation, which is called the economic speed. The power running curve of the diesel engine increases with the speed, and the power is higher. When the rated speed is reached, the rated power is exerted. Conversely, when the speed is reduced, the power is also reduced. Because when selecting a larger diesel engine model, it is necessary to pay attention to the operating speed at economical speed when matching the speed of the suction pump to the appropriate gearbox speed ratio. The gearbox speed ratio is generally based on the engine speed/sand pump speed at economical speed. The value obtained is the reduction ratio of the selected gearbox. The transmission capacity is constant or is selected according to the rated power/rated speed. .
Choosing the gearbox of the appropriate speed ratio can achieve good transmission efficiency, the diesel engine can exert the maximum function, and the sand dredge suction pump can produce more economic benefits. How to choose the gearbox of the suction pump is very important. This article is a brief introduction. I hope to provide reference for the majority of users.
