[Asia Pump Network News] Corrosion-resistant magnetic pump by the pump, magnetic actuator, the motor consists of three parts. Mainly used for corrosive liquid delivery. A wide range of corrosion-resistant magnetic pump, in recent years developed several new products, using the world's best corrosion-resistant materials, the following Xiaobian for everyone to introduce one of the new products CQB-F-type corrosion-resistant magnetic pump. First, CQB-F-type corrosion-resistant magnetic pump Product Overview: CQB-F-fluorine plastic magnetic pump is developed in recent years, new products and the introduction of foreign advanced technology, the use of polyvinylidene fluoride manufacturing, the material is the world On the most excellent corrosion-resistant materials, magnetic pumps used in the production of a wide range of materials, corrosion resistance, high mechanical strength, non-aging, non-toxic decomposition and so on. Second, CQB-F-type corrosion-resistant magnetic pump Features: Corrosion-resistant magnetic pump design not only has the general structure of a compact magnetic pump, good looks, small size, low noise, reliable operation, etc., and all of its over-current components Using the world's best corrosion resistance of the "plastic king" (Fluoroplastics) manufacturing, isolation sleeve made of special materials, with high mechanical strength, eliminating the existing magnetic eddy current phenomenon. Therefore, CQB-F fluorine plastic magnetic pump can deliver any concentration (strong) acid, alkali, oxidants and other corrosive media without any damage. Third, CQB-F-type corrosion-resistant magnetic pump installation and commissioning: (A) The magnetic pump should be installed horizontally, should not be erected, plastic pump body weight shall not withstand the pipeline, for special requirements vertical installation, the motor must be upward. (B) When the suction level is higher than the pump, the heart line, before starting to open the suction pipe valve can be, if the pump surface below the pump line, the pipeline should be equipped with the end of the valve. (C) The pump should be checked before use, the motor blades to be flexible rotation, no stuck and abnormal sound, the fasteners to be tightened. (D) check the motor rotation direction and magnetic pump steering mark the same. (E) After the motor starts, slowly open the discharge valve, to be pump into the normal working condition, and then adjust the discharge valve to the desired opening. (F) pump stop working, you should close the discharge valve, and then cut off. The usual corrosion-resistant magnetic pump, due to the delivery of corrosive liquid, consumes great. CQB-F-type corrosion-resistant magnetic pump was born, which uses the world's best corrosion-resistant materials, with high mechanical strength, non-aging, to the industry has brought great benefits.

Elevator Door System
Elevator doors have two major types, manual and automatic. Manual doors are normally opened and closed manually by hand, and automatic doors are the standard type of doors found in modern days elevators, usually powered by a door operator.
Non-automatic/manual doors
These doors are normally opened or closed manually using hands, although some of them close automatically. Most older and small European elevators from the 1950's to 1970's are using manual hinged door (similar to normal room doors), while the inside has a manual sliding scissor gate or often there is no door at all. For manual doors, sometimes the door can be spring loaded so the gate can't be left open, or the gate can automatically close when you press the button, and partly/completely close when the elevator gets to a floor. The inside door can also be a tubular gate, which is a gate that in many cases folds around the side of the cab when it is open (often called a barred gate by elevator enthusiasts, though this is likely not the actual term), and which can be automatic or manual.
These type of door is still used today, normally for smaller wheelchair lifts or home elevators. Some older freight elevators may have a horizontal or vertical manual doors. In some Asian countries, one may find an old freight elevators with manual accordion or scissor gate. Some old elevators may have a semi-manual doors a configuration of manual door outside and an automatic door inside.
Automatic doors
Automatic doors are the standard type of doors found in modern days elevators which was introduced in 1887. Almost all the automatic doors are usually powered by a door operator installed on the elevator car. Those except manual door with automatic door opening/closing device and all the incline elevators with every independent door operator belongs with every single shaft doors and car doors.
