1, M, AH and HH series slurry pumps are cantilever and horizontal centrifugal slurry pumps. It has the structure of vertical middle opening and double pump shells, and the pump body and pump cover are provided with replaceable wear-resistant metal lining or rubber lining, which can be used until it is worn out without replacement, thus prolonging the maintenance cycle and reducing the operation cost.
M, AH, HH series slurry pumps are mainly suitable for conveying highly corrosive and high-concentration slurry or high-lift slurry with low concentration and low corrosion in metallurgical, mining, coal, electric power, building materials and other industrial sectors.
2. ZJ series slurry pumps are a new generation of high-efficiency and energy-saving single-stage, single-suction, cantilever horizontal centrifugal slurry pumps, which are mainly suitable for mining, metallurgy, electric power, coal, chemical industry, building materials and other industrial industries. The pump head of ZJ series slurry pump includes pump shell, impeller and shaft seal device. The pump head and bracket are connected by bolts. According to requirements, the position of the water outlet of the pump can be installed and used by rotating at eight different angles at 45 intervals. The pump shell of the pump is a double-layer shell structure. The outer layer is a metal pump shell (front pump shell and rear pump shell), and its material is usually HT2 or QT5-7. The inner layer can be made of high chromium alloy cast iron (including volute, front guard plate and rear guard plate) or rubber (including front volute and rear volute). Product specifications range from 4ZJ-17 to 3ZJ-9, the flow range is 4-2,5, and the lift range is 9-13m. It is used to transport abrasive and corrosive slurry containing solid particles (the maximum weight concentration of solid-liquid mixture: mortar 45%, pulp 6%).
ZJ series pumps adopt the international advanced solid-liquid two-phase flow theory and are designed according to the principle of minimum loss, which is innovative in hydraulic and structural design. The geometric shape of its overflow parts conforms to the flowing state of the medium, which reduces the local and along-the-way hydraulic losses such as eddy current and impact, thus reducing its own wear, improving hydraulic efficiency and reducing running noise and vibration. Moreover, the overflow parts are made of self-developed high chromium wear-resistant alloy cast iron, which has good wear resistance, corrosion resistance and impact resistance, thus prolonging its service life. In addition, ZJ series pumps use power to reduce the pressure, which ensures that the slurry is not easy to leak and has complete specifications. It can be driven by direct connection, belt, hydraulic pressure, variable frequency speed regulation, etc., and can also be connected in series or in parallel according to the needs of users. After testing by the National Industrial Pump Quality Testing Center and appraisal by hydraulic experts, it is agreed that the overall performance of this series of pumps has reached the domestic leading level, and the efficiency index of most pumps has reached the international level. Because of its superior performance, this series of pumps have been awarded numerous honorary titles by the national electric power, metallurgy and coal industries. According to the outlet diameter and impeller diameter, this series of pumps have more than 5 basic specifications, which can meet the requirements of various working conditions. The computer selection software developed by our factory can accurately select ZJ series slurry pumps.
Compared with other slurry pumps, ZJ series slurry pumps have the characteristics of high efficiency, good cavitation performance, long service life and reliable operation. It can be widely used in conveying highly abrasive and high-concentration slurry such as tailings, refined ore sand, ash, coal slime and gravel in mining, metallurgy, electric power, coal and other industrial departments.
3. in order to meet the development needs of electric power, metallurgy, coal and other industries, aiming at the characteristics of ash removal, slag removal and slurry transportation, on the basis of extensively absorbing advanced technologies and research results at home and abroad, our factory has developed the latest generation of ZGB(P) series slurry pumps with large flow, high lift and multi-stage series connection.
the specifications of zgb (p) series products range from 8ZGB(P) to 3ZGB(P), and the caliber is 65 ~ 3mm; The flow rate is 5 ~ 1919 m3/h; The lift is 5 ~ 94 m. This series of pumps are cantilever, horizontal, single-stage, single-suction centrifugal slurry pumps and adopt modern CAD design methods, which have excellent hydraulic performance, high efficiency and low wear rate. The flow channel free from worry has good anti-blocking performance and excellent cavitation performance; Adopt combined seal and mechanical seal with auxiliary impeller and filler to ensure no leakage of slag slurry; Reliability design ensures that the mean time between failures (MTBF) of the whole machine is greatly improved (ensuring reliable operation); The metric bearings are lubricated with thin oil, and the lubrication and cooling system is set up reasonably to ensure the bearings run at low temperature. The over-current parts are made of special alloy, which has good wear and corrosion resistance; After special treatment, it is used for seawater ash removal and electrochemical corrosion of seawater and salt spray; Within the allowable pressure range, it can be used in series in multiple stages, and its allowable maximum working pressure is 3.6Mpa.
ZGB(P) series slurry pump products have obvious advantages such as high efficiency, long service life, reasonable structure, convenient maintenance, low operating cost and high reliability, and can be widely used for conveying abrasive or corrosive slurry in electric power, metallurgy, mining, coal, building materials, chemical industry and other industrial sectors, especially power plant ash. It is an ideal pump for conveying slag slurry.
4. The SP/SPR submerged pump is a vertical centrifugal slurry pump, which is immersed in the liquid and used for conveying abrasive, coarse-grained and high-concentration slurry. It doesn't need any shaft seal and shaft seal water, and it can work normally under the condition of insufficient intake.
the flow components of sp pump are made of wear-resistant metal.
the parts of p>SPR pump immersed in liquid are all lined with rubber, which is suitable for conveying abrasive slurry without edges and corners.
according to the liquid level of the slag slurry pool, pump transmission shafts or suction pipes with different lengths can be selected.
By adopting various speeds and variants, the pump can run under the best working conditions, with long service life and high operating efficiency, and can meet various harsh conveying conditions.
it is mainly suitable for conveying corrosive, coarse-grained and high-concentration slag slurry. Widely used in metallurgy, mining, coal, electric power, building materials, environmental protection and other departments.
