Product Description:

EWD-RL-SJ3 elevator load weighing device

l This system can be adopted to all kinds of elevator with three -way

  switch and 1 analog output port.

l Main features: Ultrathin character “” 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.

Q:What assembly does the vacuum packer require?
Due to incomplete questions and incomplete questions, they can not be answered normally.
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: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:Air conditioning installed in the outer machine packaging, found a small part, please master to help see what is this?
You're right. It's a balance plate for fan bladesWhen the fan leaves the factory, must make the balance verification, achieves the balance standard, can leave the factory
Q:How to package machined parts?
What questions do you ask? How to pack the machine parts, isn't it? If that is the case, I can tell you, basically the packaging machine large cast iron parts are lathe, milling machine, planer, do it.
Q:What are the main parts of small vacuum machines?
Aluminum Alloy ordinary aluminum alloy and magnesium alloy, the acid and alkali resistance, corrosion resistance, but the cost is higher, Aluminum Alloy vacuum chamber through a milling processing, the sealing surface and sealing groove is very smooth, the vacuum chamber has good sealing performance. The commonly used stainless steel plate thickness is 2-4MM, thickness of vacuum compression of easy deformation caused by weld cracking, leakage of vacuum chamber, in addition, the general on stainless steel vacuum chamber is provided with a seal groove around the plane, because of the effect of processing, the sealing groove is less smooth, vacuum sealing performance is reduced accordingly. Therefore, some models of vacuum chamber with Aluminum Alloy casting after milling under vacuum sealing groove, chamber adopts thick stainless steel plate processing into plate type, the director, make it short. When purchasing, packaging, and other solid particles relatively dry and non corrosive materials, can be used Aluminum Alloy material, and packaging with soup, salt, acid composition of higher material, can use stainless steel or aluminum magnesium alloy material. The sealing ring is generally made of silicone rubber, black rubber, a few low-grade products using foam rubber, silicone rubber, high temperature resistance, corrosion resistance, good sealing performance, long service life, the foaming rubber sealing is poor, easy to fall off, and short service life. Small treasure vacuum machine
Q:What is the principle of cleaning machine parts? How should the parts be kept after cleaning?
Mainly to remove the parts of the oil, (fine) processing residue, etc., if it is solvent based cleaning agent, as long as the dry cleaning, water cleaning, then you need to dry. According to the production requirements, if the next step directly on the production line, then there is no need to do anti oxidation measures, if stored in the storage, on the one hand packaging, but also to do anti oxidation measures.
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:Single vacuum packaging machine accessories, vacuum schedule, where to sell?
Packaging machinery specializing in the production of vacuum packaging machine, packaging machine parts, various models complete
Q:Functional configuration of plastic processing machinery
From the point of view of regional distribution of consumer market, the main consumer market China injection molding machine is gradually spread from south to north.On the export side, occupies an important position in the plastic injection molding machine Chinese export market, accounting for about 60 of total exports, 4%, earnings is accounted for 74, 1%, the main export is fully deserve.Two. ExtruderIn China's plastic processing industry, almost 1/3-1/2 of plastic products are made by extrusion. As the second major categories of products machine, extrusion molding unit production and sales accounted for about 20-25% of plastic machinery, extrusion machine plastic machinery varieties accounted for 30% varieties, the proportion is rising trend year by year.China now has more than 100 extruder production plants, mostly private or township enterprises, mainly in the plastic processing industry developed areas, such as Jiangsu and Zhejiang provinces, Liaoning, Shandong, Guangdong and other coastal areas. The total industrial output value of 124 major extruder enterprises in the country was 38 and 700 million yuan, accounting for more than 70% of the coastal areas. Capable of producing 300 units per year (sets) above extruder manufacturers only three or four companies, most companies can only produce low grade old products, to achieve economies of scale, especially in the level of control, efficiency, accuracy, reliability and complete sets of large gap compared with developed countries.Extrusion equipment made in China is mainly concentrated in small and medium machines. Large, precision extrusion units are mainly imported.Building materials, packaging films and containers as well as commodity production is the main application field market extruder.
