1. Definition of gravel pump and slurry pump

A gravel pump is a pump specially used to transport granular materials such as gravel and crushed stone. Its transport medium is generally clean water or sewage. A slurry pump is a pump specially used to transport high-concentration suspensions. Its transport medium is generally a solid-liquid mixture such as cement and ore slurry.

2. Characteristics of gravel pump and slurry pump

1. Characteristics of gravel pump:

(1) The transport medium is clean water or sewage. The granular materials are relatively large, generally not exceeding 50mm;

(2) It is suitable for mining, casting, construction and other industries. It has high efficiency in transporting sand and stone particles;

(3) When the transport pipeline is long and there are many bends, the head pressure loss is small and the efficiency is high.

2. Characteristics of slurry pumps:

(1) The medium to be transported is a solid-liquid mixture, and the particles are relatively fine, generally between 1 and 10 mm;

(2) It is suitable for mining, metallurgy, chemical industry and other industries, and has a good transport effect for materials with high concentration and fine particles;

(3) When the length of the conveying pipeline is short, its conveying efficiency is high; but when the conveying pipeline is long and there are many bends, the head pressure loss is large and the efficiency decreases.

III. Differences between the working principles of gravel pumps and slurry pumps

1. Working principle of gravel pumps:

The working principle of gravel pumps is to convert water flow into kinetic energy with the help of impellers, suck gravel and other particles into the pump body through the inlet pipe, and then centrifuge the larger particles to the outlet through centrifugal force to achieve the conveying effect.

2. Working principle of slurry pumps:

The working principle of slurry pumps is to discharge cement, slurry and other suspensions through the pump chamber in a volumetric manner, and the pump chamber rotates synchronously with the sealing partition to achieve the effect of continuous transportation.

In summary, both gravel pumps and slurry pumps are pumps for conveying solid particulate matter, but their uses and working principles are significantly different. Gravel pumps are suitable for conveying larger particulate matter and the medium is clean water or sewage, while slurry pumps are suitable for conveying finer particulate matter and high-concentration solid-liquid mixtures, and their working principles are also different.
