The function of the impeller is to directly transfer the mechanical energy of the prime mover to the liquid to increase the static pressure energy and kinetic energy of the liquid (mainly increase the static pressure energy).
The impeller generally has 6 to 12 backward curved blades.
There are three types of impellers: open type, semi-closed type and closed type.
The open impeller has no cover plate on both sides of the blade, which is simple to manufacture and easy to clean. It is suitable for conveying materials containing a large amount of suspended solids. The efficiency is low and the liquid pressure is not high; the semi-closed impeller has no cover on the suction side. There are cover plates on the other side, which are suitable for conveying materials that are easy to precipitate or contain particles, and the efficiency is also low; the closed impeller has front and rear cover plates on both sides of the impeller, which has high efficiency and is suitable for conveying no impurities. cleaning liquid. Most of the general centrifugal pump impellers are of this type.
The impeller has two suction modes: single suction and double suction.
II. Pump Casing
The function is to seal the impeller in a certain space, so that the liquid can be sucked in and pressed out by the action of the impeller. The pump casing is mostly made into a volute, so it is also called a volute. Due to the gradual expansion of the cross-sectional area of the flow channel, the high-speed liquid thrown around the impeller gradually reduces the flow rate, so that part of the kinetic energy is effectively converted into static pressure energy. The pump casing not only collects the liquid thrown out by the impeller, but is also an energy conversion device.
III. Shaft seal device
The function is to prevent the liquid in the pump casing from leaking along the shaft or the outside air from leaking into the pump casing.
Commonly used shaft seals include packing seals and mechanical seals.
Fillers are generally oil-impregnated or graphite-coated asbestos ropes. The mechanical seal mainly relies on the relative movement of the end face between the movable ring mounted on the shaft and the static ring fixed on the pump casing to achieve the purpose of sealing.
Our company can produce slurry pump spare parts, which are widely used in mining, metallurgy, coal, electric power, dredging and other sectors of the national economy. Products are sold to South America, Africa, Southeast Asia, Russia and many other countries and regions. Our products have won unanimous praise and the market.
The main components in the pump are the housing, impeller, back plate, shaft and shaft seals and motor adapter.Pumps with replaceable spare parts and components can have an unlimited lifespan. A high-quality custom mud pump with replaceable parts can last a lifetime, so it should be considered a very reasonable long-term investment.
The sealing surfaces are made of high quality, pressure free sintered silicon carbide and high quality cemented carbide. The base materials are SUS316L and 2205. The structure has the advantages of anti blocking, anti-wear and corrosion resistance, and its service life is more than twice that of ordinary mechanical seal.You can rest assured to buy slurry pump mechanical seal from us.
The shield of slurry pump is an important part of slurry pump, which is the same as the sheath and impeller
You can rest assured to buy Slurry Pump Fpl Insert from us.
Slurry pump impeller is mainly flow parts, including: impeller, pump body, pump cover, volute, front guard plate, rear guard plate, auxiliary impeller, shaft sleeve, positioning sleeve, pump shell, bracket, water seal ring, packing gland, packing box, decompression cover, labyrinth ring, etc.
A mechanical seal is a shaft sealing device of a rotating machine, which means that at least a pair of end faces perpendicular to the axis of rotation are kept in close contact and relatively sliding under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal. Constructed to prevent fluid leakage. Mechanical seal is one of the shaft seal types of slurry pumps.You can rest assured to buy mechanical seal of slurry pump from us.
The sheath of slurry pump is an important part of slurry pump and one of the overflow parts
Because its shape is like a snail, slurry pump volute liner is also called a spiral case
The material can be high chromium metal alloy and rubber
You can rest assured to buy impeller of slurry pump from our factory and we will offer you the best after-sale service and timely delivery.
