The SM type open pump is a single-stage, double-suction, horizontal, open type centrifugal clean water pump. It is suitable for industrial and urban water supply and drainage pumps. It can be used as a pump for drainage or water supply in factories, cities, power plants, and water conservancy projects, and can also be used for farmland irrigation. . The "S" series open pump is an energy-efficient product with the features of simple structure and excellent performance. For the transportation of clear water without solid particles or other liquids with physical and chemical properties similar to water, the temperature of the medium to be transported is 0°C to 80°C, and the allowable inlet pressure is 0.6 MPa.
SM type horizontal open pump parameter range:
Flow Q 88~1400m3/h
Head H 12~100m
SM type open pump model description:
6×14SM
6- spout outlet diameter (inches)
14-round maximum impeller outer diameter (inches)
S-single-stage double-suction horizontal centrifugal pump D-largest impeller outer diameter grade code (with A, B, C, D, E, F total of six files)
SM type centrifugal centrifugal pump structure type:
The SM series centrifugal pumps are horizontally mounted. The suction inlet and discharge outlet are located below the centerline of the pump shaft. The pump body is open horizontally. It is not necessary to remove the inlet and outlet pipes during inspection. The shaft seal is a soft packing seal; it can also be changed to a mechanical seal.
SM-type centrifugal pump in the direction of rotation:
Looking from the motor end to the pump, the SM series pump is turned counterclockwise. At this time, the suction inlet is at the left, the discharge outlet is at the right, and the pump rotates clockwise. At this time, the suction inlet is at the right and the discharge outlet is at the left.
SM-type horizontal open centrifugal pump main parts material: pump flow parts are made of cast iron.
Why need SMED Quick Die-Change System:
With the increasing competition in the market, plastic products faster replacement, the coexistence of more and more varieties, many varieties, small batch production, Francis production will become the mainstream, especially for the automotive industry supporting enterprises, whether it is or will be interior trim, parallel, for different models of complete. Provide qualified products. Therefore, the time interval of the mould replacement will become increasingly short, that is to say the mould replacement frequency will be higher and higher, the corresponding injection molding machine downtime will greatly increase, seriously affect the production efficiency and machine utilization rate, the delivery period is prolonged, large investment can not be effectively return. This situation has caused the domestic production and use of injection molding machine manufacturers attention, in the injection molding processing automation if not effectively solve the problem of quick die change, other production automation degree high is difficult to fully To improve the utilization rate of equipment, improve production efficiency, the whole set of equipment can only be regarded as strong, flexible response to "lame". And this problem in Western industrialized countries has been basically solved, namely: the quick die change system.
Developping stage:
(1)Pull type rotary machinery
This is a quick die change system early, typical products from the Swiss company "Staubli". The characteristics of the system are: die clamping back center, suitable for small and medium-sized injection molding machine. The mechanical structure is more complex, in the rear part of the mould clamping force back center. The advantages of this system are: die around completely open, no any clamping element for external pipe plug. The system's weakness is: die back shall be installed with uniform clamping mechanism. The clamping force and no back around, wear large mold deformation work, clamping parts of the component wear serious, no clamping element state feedback signal supply system installation, host. Maintenance is difficult, not suitable for retrofitting existing equipment.
(2) Hydraulic press plate
This is the most widely used rapid die change system, typically from Enerpac, US Aerostar, Pascal from Japan.
Now in Ningbo China,we R&D ourselves,and develop our own hydraulic press plate,widely applied in injection and stamping/punching/die casting facilities during the process of die change/mold change.
(3) Magnetic chuck type
This is the rapid development in recent years, American industrial developed countries is widely accepted and adopted the quick die change system, typical products from Italy TECNOMAGNETE (tecnomagnet) company, has more than 10 years of development of this product, production and application experience of nearly 10000 system is applied to all over the world, especially for the automotive industry supporting manufacturers. In recent years, the Swiss Staubli company and Pascal company of Japan also started from the traditional hydraulic steering system for mold development and sales force system. The system is characterized by structure and control is very simple, without any mechanical clamping elements and movement in the mold plate and the suction pole on the contact surface, no matter is the heart or peripheral, all permanent magnetic clamping, injection molding machine is suitable for various types and specifications. The advantages of this system are: convenient installation, hydraulic and fully electric injection molding machine is suitable for various specifications, clamp Force from the permanent magnetic materials, without electrical work, a clamping state real-time signal feedback to the host, to ensure absolute safety clamping; full contact surface due to uniform clamping force, mold in deformation and wear a small, precision injection molding and good consistency, prolong service life of moulds; die around without any actuator the utility, periphery pipeline. Without mechanical movement of the system, mechanical, electrical transient electrical, therefore in use without maintenance, life is very long. The weaknesses of this system is: magnetic template thickness (54mm 54mm) has a certain effect on the small mould opening stroke.
