A: travel motor Haimai Ke battery forklift lifting the hydraulic motor and variable frequency AC motor using the whole exchange, as compared with conventional direct current DC motor, a brushless motor without the loss of contact and consumables, and greatly reduce the failure rates and maintenance costs. In addition, the AC traveling DC motors with the travel motors compared with good traveling acceleration, which is equivalent to good running performance of the engine of the truck, and greater play.
Second, the DC power supply provided by the battery is usually used to drive three DC or AC motors for traveling, loading and unloading, and steering.
However, the Hayek series forklifts are equipped with two AC motors for driving the left and right and one AC motor for loading and unloading, and the steering operation is attached to the hydraulic AC motor. Therefore, the Hayek forklift saves the steering motor.
1 The travel drive motor rotates the travel wheel through the wheel-side drive gearbox on the left and right sides. Compared with an engine-type forklift, it only works when the switch of the travel joystick is turned on for the walking operation, thus saving energy.
2 The motor for loading and unloading (hydraulic motor) is directly connected to the hydraulic pump for loading and unloading, and the motor will only operate when operated by the hydraulic lever. Usually, the force required for loading and unloading of the forklift is greater than the force required for walking. Therefore, the motor for loading and unloading is a larger capacity motor than the motor for traveling (the power of the Haimai 2 ton series forklift travel motor is 4.5KW). *2; Lift hydraulic motor power is 9KW).
Three: full liquid helium steering system
The Seamax forklift uses a full oil slewing (FHPS) system. The Haimike series forklift is operated by the steering sensor on the steering wheel. The speed and oil pressure of the hydraulic motor are changed by the computer controller, and the cross-bar hydraulic rear axle is commanded to perform the steering operation. Thanks to the addition of a sensor for detecting the steering angle on the rear axle, the Hayek electric forklift gives the "synchronous steering" function for precise steering comfort.
Four: front wheel double frequency conversion AC motor wheel side drive
Seamax 1-3.5 ton series forklifts, wheel drive technology with dual travel motors. Its specialty is that it is good at dealing with bumpy roads and slippery roads. It has good cross-country walking performance, and it will not slip when driving in cold storage and turning.
Five: airtight wet disc brake system
Haimai electric forklift adopts the most advanced airtight wet disc brake system.
The airtight wet disc brake system has a longer life than the drum brake brake system and does not require replacement of a series of consumables as a drum brake system. The cost is only 0.5 liters of brake oil per year, which is very economical. In addition, due to the use of a closed system, it is highly protective against water and dust. When working in a cold storage, since the brake pads are not in contact with the air, the surface does not freeze like ordinary brakes, thus greatly improving safety.
Six: CNC electromagnetic proportional hydraulic operating system
When lifting, using the sensor inside the lifting rod, the controller changes the working value of the hydraulic valve to control the operation mode of the hydraulic system. It is the most advanced hydraulic control technology. The solenoid valve operation type is a working mode that uses a computer to proportionally control the amount of oil to prevent hydraulic fluctuations and shocks, so that the operation is more stable and safe. This way, when the operation starts or stops, there is no need to worry about the hydraulic system failure rate, and the failure rate of the hydraulic system is greatly reduced. This is the Haimai series forklift has its own patented control system.
Seven: CAN BUS technology
CAN is the abbreviation of (Controller Area Network Controller Area Network). The Can Bus technology uses the communication means of the regional network to connect the abnormal signals appearing in the network bus through a small number of wire harnesses for self-test and adjustment. By using this technology, a large number of cable connections can be reduced, the electrical failure rate is greatly reduced, and the reliability of quality is greatly improved.
The food powder sifter machine is suitable for powder and granules. It is of high efficiency and supplied with selected mesh so that the different sizes of material can be screened at one time. It is widely used in metallurgy, chemical, abrasive, glass, abrasive, construction, food and light industries.
Equipment characteristics
1). Appearance design is reasonable and safe. The structure of this machine is simply, so it's convenient to clean and maintenance.
2). The screen is strong and durable, and the material is harmless to people.
3). The plate of the whole machine is heavier than ordinary machines and has a longer service life.
4). The screen size can be changed according to customer`s request.
