switch and 1 analog output port.
l Main features: Ultrathin character “一” load sensor to direct detect the changes of the car load, there is no need to change the traction taper sleeve rod.
1. All operating parameters can be set at the spot.
2. The unique programmable output signal control method can meet the the requirements of the weighing signal of varieties of fixed car platform.
3. It is easy to operate the self-learning model at the spot. The user can choose 20~100% rated self-learning model or rated set model, quite easy to operate.
4. With the ability to amend the working parameters automatically and
self-adoption intelligent landing compensation.
5. With simulation - 10 ~ + 10 V voltage output port, matching with the speed controller to improve the performance of the elevator.
6. Small volume, convenient installation, low prices.
l Technical parameters
Being applicable to all traction elevators fixed car platform (less than 60 landings) with the load of 500kg-5000kg.
Auto accommodating to the following compensation methods: Up and down leveling; ②Up command +door zone; ③Fuzzy and intelligent.
Elevator Rated Capacity/200 (Example: The rated capacity is 1000kg, and the sensitivity is 5 kg) [This data may be affected by elevator mechanical performance]
The method of circuit parallel connection is applicable to the signal source system of DC 12-32V. Also, the interior fault of this system does not affect the original operation mode of elevator.
Programmable universal signal
①3-channel programmable output models are: no load, light load, semi load, full load, heavy load, rated load, and overload(customer may set the changing range freely.)
②Each channel can be programmed as dynamic Close or Open contact.
③ Contact Capacity: DC/AC 48V/100mA
Overall Compensation Range 0-10V, -10V~+10V. 0V~+5V
≦0.5 Second, The communication distance between the intelligent and control is 0-400m.

- Q:After the powder metallurgy parts are machined, how to prevent rust?
- 1, the traditional method: soak kerosene can be short-term rust prevention, but do not expect long-term rust prevention or transportation process rust prevention, rust prevention period is generally in 1-3 months or so.
- Q:A workshop needs to be packed with machine parts. 5 boxes are packed in 80
- 5 boxed with 8020 boxes are 4 times as many as 5 boxesIn other words, the 4 5 boxes are 20 boxes80 x 4=320So I can't finish it
- Q:What is the definition of machining process specification?
- For example, a common part of the processing process is rough - finishing - assembly - Inspection - packaging, is a general process of processing
- Q:The true size of a mechanical part is based on what is on the drawing
- The most accurate size is dimensioning! You can't draw correctly, but as long as the marking is correct, the processing is in accordance with the dimensioning!
- Q:What's the price difference between feed packer and organic fertilizer packing machine?
- So in this parts material to the high requirements, each component costs are not the same, the price of natural Many a little make a mickle., also went up.
- Q:What is the principle of cleaning machine parts? How should the parts be kept after cleaning?
- The cleaned parts should be kept in a dry, ventilated place and coated with a thin layer of butter when necessary. Flat type parts must be flat, the middle shall not be suspended; shaft parts can not be placed flat, must be vertical suspension, to prevent bending.
- Q:How is the vacuum packing machine assembled? How many parts?
- Vacuum chamber, etc.. Qingdao AI Xun vacuum packaging machine using high quality parts and components
- Q:What are the components of mechanical equipment (automatic equipment)?
- I have been away from this industry for a long time, and I can't give you any specific suggestions. But I think you should be more specific in the process of machining. It is estimated that it is a precision machine component, and the material requirements are relatively high. But I think in principle, we should look for local steel mills with special steel production capacity, and the other one depends on the local technical strength, such as northeast China and Shandong, where the strengths are in large equipment. Jiangsu Shanghai side of the precision mechanical technology strength in the country should be relatively strong.
- Q:Gearbox mechanical parts, mechanical and electrical products?
- It's definitely not standard. It means structure, size and painting,
- Q:Functional configuration of plastic processing machinery
- After 80s, China's injection molding machine industry developed rapidly, with an annual growth rate of more than 20%, and gradually formed a processing base mainly in Zhejiang, Ningbo, Guangdong, Dongguan and Shunde. Among them, Ningbo injection molding machine production and sales accounted for more than 60% of the total production and sales. In 2002, the production and sales volume of the whole machine has reached 30000 units. In 2003, it was estimated to reach 35000 units, accounting for about 60% of the total annual output of China's mainland and about 30% of the world's total output. Ningbo is only one city, there is the size of the injection molding machine production enterprise more than 100, including the world's first production and sales of the China Haitian Machinery Co. Ltd. and more than 10 foreign-funded enterprises, involving companies more than hundreds of.China's large backbone injection molding machine manufacturing enterprises are mostly joint ventures, introducing foreign advanced technology and management mode. In terms of technology, the injection molding machines produced in China have been developed from ordinary models to large machines, electronic machines, oil and electric machines and special injection molding machines. Among them, the Haitian developed China's largest clamping force injection molding machine, used in the production of auto parts; Zhen Xiong developed a full electric disk machine for the production of special machines and PET bottles for injection molding special models. Although on the whole, the injection molding machine Chinese production is mainly low-end products, but to the Haitian injection molding machine manufacturing enterprises and Zhenxiong as the representative of the effort to end market development.
