The multi-stage pump has a wide range of applications   Multistage pump is a kind of centrifugal pump, which is composed of inlet and outlet section and middle section through pull rod. Its output water pressure can be very large, and it also depends on the rotation of impeller to obtain centrifugal force, so as to reduce the material consumption. When the gas density reaches the working range of the mechanical vacuum pump, it is pumped out, so as to gradually obtain high vacuum.   Multistage pump is to achieve suction, compression and exhaust by the change of pump cavity volume, so it is a variable volume centrifugal pump.

Desulfurization Pump Desulfurization pump is a kind of pump that can adapt to various working conditions, such as conveying acid, alkaline clear liquid or slurry; All kinds of corrosive pulp in smelting industry; All kinds of dilute acid in sulfuric acid industry; All kinds of sewage in environmental protection industry. The pump is not only corrosion-resistant and wear-resistant, the use of a very wide range.It has the following characteristics: 1、Desulfurization pump has strong wear resistance: all flow passage parts are made of steel lined ultra high molecular weight polyethylene (UHMW-PE). The wear resistance of UHMW-PE ranks first among plastics, which is 4 times higher than nylon 66 (PA66) and polytetrafluoroethylene (PTFE), and 7-10 times higher than carbon steel and stainless steel. 2、Desulfurization pump has strong impact resistance: the impact strength of UHMWPE ranks first among general engineering plastics, which is 5 times of that of (acrylonitrile / butadiene / styrene) copolymer (ABS), and can maintain stability at minus 196 ℃, which is a characteristic that no other plastics have. 3、Excellent corrosion resistance of desulfurization pump: the pump can resist all kinds of corrosive media (acid, alkali, salt) and organic solvents within a certain temperature and concentration range, and can be immersed in 80 kinds of organic solvents at 20 ℃ and 90 ℃ for 30 days. There is no abnormal appearance, and other physical properties are almost unchanged 4、No noise in desulfurization pump: the impact energy absorption of UHMWPE is the highest value in plastic, and the sound attenuation is good, so that the noise generated by liquid flow is minimized in the process of transportation. 5、Desulfurization pump Safe and reliable, no toxin decomposition: the pump used ultra high molecular weight polyethylene (UHMW-PE) chemical properties are extremely stable, so it is also suitable for use in the food industry. 6、Low friction coefficient of desulfurization pump: the internal friction system of the pump is only 0.07-0.11, so it has self lubrication. Under the condition of water lubrication, the dynamic friction coefficient is half lower than that of PA66 and POM. When working in the form of sliding or rotating, the lubricity is better than that of steel and brass with lubricating oil. 7、Good viscosity resistance of desulfurization pump: ultra high molecular weight polyethylene (UHMW-PE) has excellent viscosity resistance, and its adhesion resistance is equivalent to that of PTFE, so it is also outstanding in conveying some media with high viscosity. 8、Desulfurization pump can transport strong acid and other liquids, suitable for medium: sulfuric acid with concentration less than 80%, nitric acid with concentration less than 50%, hydrochloric acid with various concentrations, liquid alkali, both clear liquid and slurry.

Slurry Pump Slurry pump can also be called metal pump, wear-resistant pump, industrial pump, accident slurry pump, ash filling pump and filter pump.The name of slurry pump is different. We can know that slurry pump is widely used in industry, mining and other large industries. Slurry pump can be widely used in mining, power, metallurgy, coal, environmental protection and other industries to transport slurry containing abrasive solid particles. For example, transportation of mineral slurry in metallurgical concentrator, hydraulic ash removal in thermal power plant, transportation of coal slurry and dense medium in coal preparation plant, dredging of river channel, river dredging, etc. In the chemical industry, it can also transport some corrosive slurry containing crystal.   First of all, about 80% of the applications in mineral processing plants are used in mineral processing plants in the mining industry. Due to the poor working condition of ore primary separation, the service life of slurry pump in this section is generally low. Of course, different ores have different abrasivity. If the relative abrasiveness of the concentrate conveying section is reduced, the overall service life of the pump will be longer. Therefore, when the general users often ask about the service life of the products of the suppliers in the procurement process, strictly speaking, any manufacturer will not promise an accurate service life cycle for the users without any basis, because the service life of the flow passage parts (wear-resistant and corrosion-resistant parts) depends on many different factors, The diversity and complexity of working conditions lead to different service life of materials with the same quality.   In thermal power plants, due to the use of a large number of coal-fired power generation, the slag or ash after coal combustion needs to be removed. The slurry pump is used to remove the ash. After mixing a certain amount of water, the slag is transported to the place where the ash is stacked by the slurry pump. Therefore, sometimes the slurry pump also becomes the ash pump in the power plant.   In the coal washing industry, due to different working conditions, large coal lump and coal gangue are easy to block, so the design requirements for slurry pump are very high   In the field of sea water sand selection, slurry pump application has gradually been recognized by customers. But in the sea water, sand in the river, slurry pump is more easily called sand pump, dredge pump. Although the method is different, it can be called slurry pump generally from the aspect of structure characteristics and pump performance principle. Therefore, in this sea water sand selection, we often call sand pump, in the river dredging is used to be called dredge pump. Although the application of slurry pump is wide, it is very important to apply it correctly. Because of the limitation of its name, some people who are not in this industry misunderstand it. In fact, mud pump, impurity pump, dredge pump, silt pump, etc. are all used in the application scope of slurry pump. In the application of slurry pump, it is very important to pay attention to the reasonable design, correct calculation and proper selection.

Its main working parts include the screw of eccentric helicoid(called rotor) and the screw bush with a double-line helicoid on its inner surface(called stator). Its working principle goes like this: when the electric motor drives the pump shaft t rotate, the screw rotates around its own axes on one hand and rolls along the inner surface of the bush on the other, thus forming a seal cavity in the pump. When the screw rotates a cycle, the liquids in the seal cavity will advance a screw pitch forward. With the continuous drive of the screw, the liquids will press from a seal cavity to another cavity in a spiral manner until it is pressed out of the pump body finally.
