Product introduction: SGR vertical hot water pipeline pump is suitable for fluid medium transportation, high-pressure supercharging, water supply, air conditioning, heating cycle, fire and spray water supply, living community fountain control, fiber-containing sewage discharge, automatic control, frequency conversion operation, heating High temperature hot water pressurization cycle in industries such as boilers. The use temperature is below 150 °C. [details...] The selection of pipeline pump should be based on the process flow, water supply and drainage requirements, from five aspects, including liquid delivery, device head, liquid properties, pipeline layout and operating conditions. 1. Flow rate is one of the important performance data of the pump selection, which is directly related to the production capacity and conveying capacity of the entire device. For example, in the design of the design institute, the normal, minimum and maximum flow rates of the pipeline pump can be calculated. When the pump is selected, the normal flow rate is based on the maximum flow rate. When there is no maximum flow rate, the normal flow rate can be taken as the maximum flow rate. 2. The head required for the system is another important performance data of the pump. Generally, it should be selected by amplifying the 5%-10% balance. 3, liquid properties, including liquid media name, physical properties, chemical properties and other properties, physical properties are temperature c density d, viscosity u, solid particle diameter and gas content in the medium, etc., which involves the lift of the system, effective gas Calculation of the amount of eclipse and the type of suitable pump: chemical properties, mainly refers to the chemical corrosiveness and toxicity of the liquid medium, is an important basis for the selection of the pump material and the type of shaft seal. 4. The piping arrangement conditions of the equipment system refer to the data feeding height, liquid feeding distance, liquid feeding direction, suction side, minimum liquid level, discharge side maximum liquid level, and other data and pipe specifications and length, material, pipe fittings specifications and quantity. Etc., in order to carry out the calculation of the combing process and the checking of the NPSH. 5, operating conditions have a lot of content, such as liquid operation T saturated steam force P, suction side pressure PS (absolute), discharge side container pressure PZ, altitude, ambient temperature operation is gap or continuous, pump position is fixed Still removable. Demolition type single stage pipeline pump The pipeline pump is suitable for industrial and urban water supply and drainage, high-rise building water tower pressurized water supply, fire booster, pipeline pressurization, long-distance water supply, heating and refrigeration cycle and other occasions. This series of pumps has the advantages of stable operation, reliability, low noise and wide application range. It is an ideal single-stage single-suction centrifugal pipeline circulation booster pump. FG type pipeline pump This series of pumps is based on the international ISO2858 standard, and adopts the latest hydraulic model. At the same time, it is designed and developed into an alternative to the SG type pipeline pump with reference to relevant international standards. The technical standards, performance parameters, test methods, etc. used by the IS-type centrifugal pump are effectively used in the ISO international standard, and have the same performance parameters as the IS-type centrifugal pump, and all of its performance indicators meet the design requirements. DFRG centrifugal pump The pipeline pump is based on the international ISO2858 standard and adopts the latest hydraulic model. It is also designed and developed as an alternative to the SG pipeline pump with reference to relevant international standards. The technical standards, performance parameters, test methods, etc. used by the IS-type centrifugal pump are effectively used in the ISO international standard, and have the same performance parameters as the IS-type centrifugal pump, and all of its performance indicators meet the design requirements.

Galvanized Roller Shutter Door

Using advanced hot-dip galvanized material , precision roll forming production process, polyurethane foam that free of hydrofluorocarbon inside door, light weight, high strength, appearance nice. The doors have advantages of tamper anti-theft , noise isolation thermal insulation and corrosion resistance;the doors are widely used in shops, garages, houses, supermarkets, warehouses and industrial plants,etc.

Depending on the characteristics of the buildings,we can choose interior, exterior and intermediate three different installation ways, doors stay in the upper part of door after rolling up , this could save garage space, and also could keep the garage clean and beautiful by prevent the mud, rain and snow ,etc going into the garage.
