High Chrome gravel pump is mainly used for continuous conveying of strong abrasive material slurry that is too large and cannot be conveyed by ordinary slurry pumps, such as dredging by dredgers, sand extraction by sand mining ships, dredging of river channels, mining and metal smelting blasting slag delivery, etc.
Features of High Chrome Gravel Pump:
MG type gravel pump is an imported technology product. The pump adopts a single pump casing structure connected by a cassette. It is a single-stage single-suction cantilever centrifugal pump. It has light weight, good cavitation performance, anti-corrosion It has the advantages of strong abrasiveness, wide flow passage, convenient installation and use, etc. It can continuously transport large particles of strong abrasive mud and sand.
Structure of High Chrome Gravel Pump:
This series of gravel pump is composed of pump head, sealing assembly, bearing assembly, bracket, etc. The bearing lubrication method is grease lubrication. The impeller, the pump body, the front guard and the rear guard are all made of strong wear-resistant high-chromium alloy or wear-resistant alloy steel, and the hardness is not less than 58HRC.
The sealing form of the High Chrome Gravel Pump:
Packing seal, auxiliary impeller seal, packing plus auxiliary impeller seal, mechanical seal and other types.
The transmission mode of the High Chrome Gravel Pump:
V-shaped V-belt transmission, elastic coupling transmission, gear reduction box transmission, hydraulic coupling transmission, variable frequency drive device, thyristor speed regulation, etc.
With a variety of speeds and variants, it has a long service life and high operating efficiency, and can meet many types of harsh conveying conditions.
The drive method of High Chrome Gravel Pump:
Electric motor driven and Diesel engine driven
In the shipbuilding industry, there are generally more than 100 pumps used on each ocean-going ship, and their types are also various.
Others, such as water supply and drainage in cities, water for steam locomotives, lubrication and cooling in machine tools, conveying bleach and dyes in the textile industry, conveying pulp in the paper industry, and conveying milk and sugar foods in the food industry, all require a large amount of water. mud pump.
From the performance range of the mud pump:
The flow rate of the giant pump can reach more than hundreds of thousands of cubic meters per hour, while the flow rate of the micro pump is less than tens of milliliters per hour; the pressure of the pump can be as high as 19.61Mpa (200kgf/cm2) from normal pressure; the liquid to be transported The lowest temperature is below -200 degrees Celsius and the highest can reach above 800 degrees Celsius. There are many kinds of liquids transported by pumps, such as transporting water (clean water, sewage, etc.), oil, acid and alkali, suspension, and liquid metal.
In agricultural production, pumps are the main irrigation and drainage machinery. my country's rural areas are vast, and a large number of pumps are needed in rural areas every year. Generally speaking, agricultural pumps account for more than half of the total pump output. Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to be drained by a pump. In the process of beneficiation, smelting and rolling, it is necessary to use a pump to supply water first. In the power sector, nuclear power plants require nuclear main pumps, secondary pumps, and tertiary pumps, and thermal power plants require a large number of boiler feed pumps, condensate pumps, circulating pumps, and ash pumps, etc. In short, whether it is aircraft, rockets, tanks, submarines, or Drilling, mining, trains, ships, or everyday life requires pumps everywhere, and pumps are running everywhere. That's why the pump is listed as a general-purpose machine, which is a major product in the machinery industry.
