Mud pump impeller structure suitable for different kinds of soil and design method of mud pump impeller structure

Abstract

The invention provides a mud pump impeller structure suitable for different kinds of soil and a design method of the mud pump impeller structure, and belongs to the technical field of mud pump design.According to the technical scheme of the design method of the mud pump impeller structure suitable for the different kinds of soil, particle diameter parameters of dredged soil and the blade wrap angle are added according to a calculation formula of the blade number of a clear water pump impeller, and a blade number calculation formula of a mud pump impeller is designed; and furthermore, the blade number Z of the mud pump impeller is determined according to the designed blade number calculation formula of the mud impeller. Compared with the prior art, the mud pump impeller structure suitablefor the different kinds of soil and the design method of the mud pump impeller structure have the beneficial effects that according to dredged soil changes under different dredging working conditions,one impeller suitable for the corresponding soil can replace a previous impeller for a mud pump, and the mud pump is enabled to run efficiently all the time under the condition of guaranteeing that the mud pump is not blocked.

Description

technical field [0001] The invention belongs to the technical field of mud pump design, and in particular relates to a mud pump impeller structure suitable for different soil properties and a design method thereof. Background technique [0002] Sediment transportation is a key link in dredging engineering, but in the actual dredging process, the dredged soil quality in the dredging pump is not always constant. Depending on the depth of excavation in different areas or in the same area, different dredging soils will appear, including block stones, gravel, clay, medium-coarse sand, silt-fine sand, silt, silt, etc. In actual engineering, the mud pump wears quickly when transporting soil such as block stones, gravel, and medium-coarse sand, while it wears slowly when transporting soil such as silt and silt. After the mud pump is worn out, the overall replacement cost is high and the cycle is long. In order to cope with different working conditions, multiple dredge pumps cannot...

Problems solved by technology

After the mud pump is worn out, the overall replacement cost is high and the cycle is long

In order to cope with different working conditions, it is impossible to prepare multiple dredge pumps on the construction ship

[0003] In the design of existing dredging pumps, large particles are often considered comprehensively, passing capacity, wear, efficiency, cavitation and other factors, and the final design scheme can meet the dredging requirements, but it cannot guarantee the best efficiency when dredging different soil types

[0004] In the design process of the mud pump, if only large particles are considered, one of the factors such as passing capacity, wear, efficiency, cavitation, etc., can often greatly improve the performance of this aspect, while sacrificing other aspects of performance, such as the passage of large particles. Very capable pump, not too efficient
