ZJ slurry pump Domestic also known as EZJ slurry pump, is a pump for conveying abrasive slurry containing solid particles in the power, metallurgy, coal, building materials, chemicals and other industrial sectors can find its shadow , Is an effective helper in industrial production. Features and Uses of ZJ Slurry Pump 1. Characteristics of ZJ Slurry Pump With the development and improvement of impurity pump technology, the theory of modern fluid mechanics, modern mechanical theory and computer software design are combined with user feedback experience. Introduced the ZJ slurry pump, the series of slurry pump with a full model, wide coverage of performance conditions, easy selection and so on. ZJ slurry pump designed for single-stage, single-suction, centrifugal slurry pump. According to the structure is divided into horizontal (EZJ series) and vertical (EZJL series). Horizontal pumps are divided into 350mm, 300mm, 250mm, 200mm, 150mm, 100mm, 80mm, 65mm, 50mm, 40mm and so on according to the diameter of the outlet. Different sizes of impellers are available for different diameters according to the head. ZJ slurry pump is innovative in hydraulic design and structural design. Its over-current components are made of high-chromium wear-resistant alloy cast iron which is self-developed and has high efficiency, energy saving, long service life, light weight, reasonable structure, Reliable operation, small vibration, low noise, easy maintenance and other significant features. The pump body adopts double pump shell structure to facilitate the replacement of over-current components; the outer pump shell adopts nodular cast iron or gray cast iron according to the pressure needs, and the inner pump shell adopts high chromium anti-wear white cast iron or cast steel. (B) the use of ZJ slurry pump ZJ slurry pump is mainly used in electric power, metallurgy, coal, building materials, chemicals and other industrial sectors, mainly used to transport abrasive slurry containing solid particles, such as concentrate processing plant and Tailings, power plants in addition to ash, coal preparation plant coal and heavy medium coal, coastal river mining operations transport pulp. Its ability to deal with pulp 宓 淖 She 笾 亓 ǘ Ren? Ren ram? 5%, pulp 60%; According to user needs can be run in tandem. Sealing form: ZJ slurry pump can be combined impeller plus packing seal and mechanical seals in the form of two shaft seals. (1) Auxiliary Impeller Power Seal: Auxiliary Impeller Seal A pressure seal, packing, or lip seal created by the impeller and tandem impeller as a parking seal. In the pump inlet pressure is not greater than the value of the pump outlet pressure of 10% of the single-stage pump or multi-stage series of first-stage pump, you can use this form of seal. It can run without shaft seal water, does not dilute the pulp, sealing effect is good and so on. But will increase the power consumption (generally need to increase the shaft power of about 5%). Packing seal is a common form of shaft seal, suitable for a variety of working conditions, matching PTFE packing, graphite packing and other special materials, can be used in corrosive or high temperature conditions. It has the advantages of simple structure, easy maintenance and so on. (2) mechanical seal: the use of the world's leading sealing technology, sealing effect is good. Cartridge structure to make installation and replacement more convenient, different structural forms to adapt to different working conditions. The friction material is made of high hardness ceramic and alloy. The mechanical seal and the seal box are designed and matched to meet the medium flow conditions. Therefore, it has high abrasion resistance and shock resistance, and can satisfy customer's satisfaction under various adverse conditions. (Editor: Huang Nengwen QQ :)
