Pumps are among the most practical equipments that are used in many industries today and are classified in different categories based on various factors such as power, performance, number of work steps, cooling method, etc. The sludge pump is one of the types of submersible centrifugal or centrifugal pumps that have different types and can be used for suction and pumping of fluids such as mud, mud, etc. Basically, these pumps have a lot of power and are used to pump all kinds of viscous fluids and were used for the first time in 1960. In the following article, it will be fully investigated what a sludge pump is, how many types it includes, how it works, and finally, what are its benefits and applications.
What is the sludge pump?
In general, a pump is a device that is able to mechanically move fluids (gases and liquids) and based on the mechanism of moving fluids into three main groups: direct lift pumps, displacement pumps and Gravity pumps are divided. The sludge pump is a type of pump that is used for pumping and moving viscous fluids due to its high power. Before the invention of these pumps, dense fluids, wastes or micro-solids mixed with water and other liquids in various industries were transported out of the structure by pipes, and due to the lack of sufficient pressure, disposal of these materials near the structure or sometimes even in There were places of passage, which created various challenges and problems. These pumps have the same performance as floor pumps.
how the sludge pump works
As mentioned, sludge pumps are in the category of centrifugal pumps and their design is such that the pump impellers have backward curved blades and can be open or covered. Half-open propellers only have a back cover, and closed propellers are covered from the front and back, and finally, open propellers will not have any cover. Semi-open impellers are usually used in sludge pumps. In general, in these pumps, the electric motor drives the pump, and from the inlet part of the pump, fluid containing fine or coarse solid particles enters the pump, and finally, with the rotation of the impeller, the speed of the fluid increases and is directed towards the outlet. >
The distance between the blades of the propeller will be enough for the solid materials to easily enter the pump and be destroyed by the liquid and not to block it. Also, for fluids containing large solids, propellers with fewer blades are used. The smaller the number of pump impellers or the greater the distance between them, the less likely it is to clog and block the pump, although these types of pumps are less efficient.
Types of Sludge Pumps
Sludge pumps such as vacuum pumps and other types of pumps can be classified based on several factors and parameters and have a great variety. In terms of how these pumps are designed, they can include simple pumps, float pumps (with electric cut-off), air pumps (pneumatic), European explosion-proof (EX) electric pumps (for transporting flammable chemical fluids, explosions, all types of oil derivatives with body cast iron and three-phase), indoor condenser pumps and outdoor condenser pumps.
In terms of cooling, these pumps can be available as water-cooled and oil-cooled pumps. In terms of the types of impellers, sludge pumps include different types such as single-channel, double-channel, semi-open impeller, open impeller, vortex impeller, etc. In terms of how to install, sludge pumps can include fixed sludge pumps and mobile sludge pumps, but in general, sludge pumps are classified based on the way of use and can be divided into two main categories.
floating or sludge pumps
This type of sludge pumps are completely placed inside the fluid and are immersed in it. The electric motor of these pumps is completely sealed and the placement of fluids around it makes it cool faster and has better performance and efficiency. The degree of protection of this type of pump is IP68. When these pumps are not placed inside the fluid, excessive heat may cause the engine to burn, that's why they must be immersed inside the fluid. When the pump cools down well, reducing the engine flow will increase the efficiency of the sludge remover and will be effective in its greater efficiency.
Vertical sludge pumps
Vertical sludge pumps are another type of sludge pump, where the electric motor is placed outside the fluid and unlike submersible pumps, it is not immersed in the fluid. In these pumps, the electric motor is connected to the pump by means of a coupling and can be separated. These pumps are also known as dry pumps because the pump is placed on top of the liquid and performs suction through a pipe.
most important applications of sludge pump
As mentioned, sludge pumps, like water pumps, vacuum pumps, etc., can be classified based on different factors and parameters, and each of them can have different power. Among the most important applications of sludge pumps, the following can be mentioned:
- از این پمپها میتوان برای انتقال و جابجایی مایعات دارای ذرات جامد مانند الیافهای بلند استفاده کرد.
- این پمپهای قابلیت پمپاژ و انتقال سیالات دارای ذرات سایشی را دارند
- برای انتقال و جابجایی انواع فاضلآبهای صنعتی به کار میروند و میتوانند آبهای آلوده به مواد مختلف و آبهای گلآلود را جابجا کنند.
- برای انتقال و جابجایی سیالات حاوی آب و گاز و همچنین انتقال و جابجایی لجن پساب صنعتی مخلوط با آب کاربرد دارند.
- انتقال و پمپاژ در خمیر کاغذ و صنعت فولاد سازی استفاده های متعددی خواهند داشت
- برای پمپاژ سیالات خورنده به کار میروند
- در صنایع مختلفی همچون صنعت چوب، کاغذ، چرم، رنگ و رزین، کشاورزی، غذا و دارو و … کاربردهای متعددی دارند.
