Active Protection technology design and passive means of combining explosion
General domestic design electric forklift explosion commonly used technique is to take flameproof, intrinsically safe, increased safety and other means to prevent or control the explosion occurred in an explosion after explosion in vivo, but also in the circuit design simple as possible, reducing line liftstar electric riding pallet jack and reduce the spark control point, for the aging, insulation performance by artificial periodic inspection, greater security risks.
The so-called Active Protection technology is in the whole circuit design with advanced sensing, short circuit protection, insulation monitors and other electronic components and intelligent control system combines the technical parameters set up by the program proof, so you can proof the performance of the machine automatic control to avoid the security risks caused by human activity. And can heat up, down and the secondary current limiting thermal control technology, you can control the operation of the vehicle, to work longer hours.
c) a reasonable application of advanced technology to develop explosion-proof accessory products
Explosion-proof electric forklift design, to keep up with international advanced technology development, especially electronic, hydraulic technology developments in the field, such as: electronic surveillance products, hydraulic wet braking, etc. are no domestic technology in the rational use of At the same time, to the related domestic manufacturer of professional and technical cooperation, development of key technologies to achieve localization of products, to develop its own technology to design and have to master the core technology and supporting the key vendors in close technical collaboration, so as not to appear to develop product because of the relatively low domestic manufacturers and technology platforms reach the technical requirements.
2, the development direction of the explosion-proof electric forklift
With the development of AC permanent magnet technology, explosion-proof electric forklift operation control system will also develop in the direction of AC permanent magnet, brushless maintenance-free due to their nature, avoid because clearing brushes powder and replacement brushes and open Explosion security risks caused by the body. On low speed dynamic performance can achieve constant torque control, constant power control can be high-speed efficiency, and with a variety of operating conditions of the energy recovery, anti-slipped, and other functions, the electric explosion proof forklift with a low current, low noise, high transmission efficiency security is strong, low temperature rise characteristics of advantages.
Explosion-proof electric forklift will use advanced electronic technology to
liftstar electric pallet trucks continuously improve the level of protection of the machine, it has automatic protection capability in high intelligent control, the explosion of electronic components intelligence, integration, miniaturization.
Explosion-proof electric forklift in the overall design should have a user-friendly design ideas, and to improve driver comfort, easy maneuverability, reduce labor intensity of the driver, and to ensure rational distribution under the premise of the whole tipping safety performance, achieve handsome in appearance and effect.
Improve the technical standards of electric explosion proof forklift, corporate standards can not stay in the national standard level, just be satisfied to meet national standards on the line, companies must continuously improve manufacturing technology and product performance, develop high technical standards, in order to promote the national technical standards upgrade, eliminate backward enterprises, so that explosion-proof electric forklift manufacturing level holistic development.
Cylindrical roller and raceway line contact bearings
Is a professional bearing and industrial machinery equipment parts company , supporting bearings and industrial services experience in the industry for many years , in the new and old customers have a good reputation. Companies Agency of Japan , Europe and the United States and a number of internationally renowned business brand. Cylindrical roller bearings Cylindrical roller and raceway line contact bearings. Load capacity, the main radial load. Rolling friction ring ribs and small , suitable for high-speed rotation . According ring without ribs , can be divided NU, NJ, NUP, N, NF and other single row bearings , and NNU, NN and other double row bearings. The bearing is the inner, outer separable structure . Inner or outer wall of the cylindrical roller bearings, the inner and outer ring can be moved relative to the axial direction , so it can be used as free- end bearings. In the inner and outer side of a double wall , the other side of the ring has a single wall of the cylindrical roller bearings, can withstand a certain degree of axial load direction . General use of steel stamping cage , or copper alloy machined cage . But there are also a part of the use of polyamide forming cage .
The main features of electric cars are
The main features of hand truck are: 1, the volume of hydraulic equipment , simple operation, easy to use. Ergonomic handle design with three functions : Lifting, Handling , put down . 2, the body casting cylinders, beautiful appearance , durable , high-quality steel to build , chrome live 3 , rod , internal relief valve provides overload protection, decreased speed control spool with a whole piece , reducing maintenance costs. Workshop cargo handling is a good helper . The main features of electric cars are: 1 , heavy design, compact structure , suitable for small spaces ; 2 , all control components are concentrated in the handle ends , simple operation, without professional driving ; 3 , high-efficiency DC traction motors, traction, walking speed walking, can withstand heavy material handling ; 4, the lifting system using integrated pump stations, start button that can enhance the material gently hold , starting declined button , hydraulic auto-reply , the material can slowly put down . The difference between manual and electric pallet truck truck between : The first is the difference between the power system : hand pallet trucks are transporting goods by human lifting , all-electric truck powertrain as the name suggests is overweight by motor power handling ; Followed by driving different technical requirements : hand pallet trucks can operate basically the general staff . All-electric truck was equipped with professional drivers ; Once again, different performance and price : High performance all-electric truck efficiency , operational flexibility , handling speed. All- electric cars is much higher than the price of hand pallet trucks . longlonglonglonglonglongThis article is more original content Sen Muda Suzhou Industrial Equipment go to what kind of electric forklifts
Jane brake pedal controls the volume
cargo promotion . Lifting the handle will pull to the " up" position, release the brake drum pedal controls the lifting speed . Observe the lifting motor current value when the current is less than ll oA can continuous operation ; current exceeds lloA (Jm: < 155A) , the starting time should be 71 Ding an operating cycle time of 15%.
( 2 ) the goods stay in the air . Release the accelerator pedal , the brake pedal depressed reel and levers in place. If the goods need to be in the air longer stay , you also need to pull the switch in the " Electric" position to ensure safety.
( 3 ) gravity drop. Lifting the handle in the neutral position . Jane brake pedal controls the volume . Lifting lowering speed shall not exceed 1.5 times the speed . Work process in order to avoid danger .
Electrically operated ( pull switch in the " Electric" position ) ;
( A ) cargo promotion . Loosen the drum brake pedal , pull the handle to the frame lifting " up" position tube , feet stepped on the accelerator pedal to control the lifting speed . Precautions with the " mechanical " manipulation.
( 2 ) the goods stay in the air . Release the accelerator pedal , the lifting levers in place, if the goods are to be in the air for a long stay , you can simply roll the brake pedal depressed , to ensure safety.
