Structural description
The YW pump is a single stage single suction pump. The pump is used to connect the hydraulic components of the pump and the bearing body and supporting disc. The liquid is discharged by the outlet pipe parts. The impeller is a semi open impeller, and the impeller is equipped with a stirring blade at the inlet extension of the impeller blade to transport the medium containing the particles. The maximum underwater depth of the pump is 8m. When the length of the liquid is over 1.5m, the shaft structure should be adopted and the rolling bearing (grease lubrication) is installed near the shaft, and the coupling sleeve is used. The bottom rolling bearing of the pump is separated from the liquid surface by mechanical seal and does not touch the liquid. The pump bearing has enough rigidity to ensure the balanced operation of the pump. If you are running deep, you can add a suction pipe (marked in the contract).
Zibo Boshan Zhize slurry pump co., Ltd. produced liquid-driven slag slurry pump, core-pulling machine, aerated concrete special pump GmbZ series slurry pump, desulphurization pump-YW-series liquid sewage pump, long shaft pump-YZR series hot oil pump and QSW series chopping pump WX series non-clogging swirl pumps, QW series submersible pumps, core-pulling machines for oil refineries to overhaul heat exchangers, and is a company specialized manufacturing companies for various series of corrosion resistant pumps. Strong technical force, complete process equipment, cast iron, cast steel, special metal manufacturing, non-ferrous metal precision casting, mechanical processing, heat treatment, assembly, performance testing and other comprehensive production capacity. Dedicated to solve all kinds of problems for the majority of users, and provide the latest products.
Company staff, science and technology personnel, pioneering, continuous development of mechanical products suitable for the domestic and international market, the majority of customers praise. The overcurrent parts of each series impurity pump have been carefully developed and tested repeatedly. According to the requirements of different user uses and medium content, various kinds of high strength wear-resistant and corrosion-resistant materials have been selected, which have solved the wear and tear of equipment in the production process for the majority of users. Corrosion, short operation life of the difficult problem, liquid slurry pump, do not need to inject water, backflow stirring in the work, mechanical crushing, not afraid of blockage, widely used. Our company can also for thermal power plants, refineries, coking plants, steelmaking plants, chemical plants, coal mines, all imported equipment with production and matching, for users to meet the urgent needs, saving a lot of foreign exchange.
