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.

l Technical parameters

1.

Application

Being applicable to all traction elevators fixed car platform (less than 60 landings) with the load of 500kg-5000kg.

2.

Floor Compensation

Auto accommodating to the following compensation methods: Up and down leveling; Up command +door zone; Fuzzy and intelligent.

3.

Sensitivity

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]

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:The true size of a mechanical part is based on what is on the drawing
The actual size of the machine parts is based on the numerical values of the drawings.The basic rules of dimensioning in mechanical drawings, such as:
Q:Hardware, furniture accessories, packaging machines exported much?
It's a little upset, but it's ok. This is more clear logistics.
Q:How to package machined parts?
If it's not rusted, clean it and wrap it in a bubble bag. Place it in a cardboard box or wooden case
Q:What are the main parts of small vacuum machines?
On the vacuum chamber, opening displacement and balancing deviceThe commonly used vacuum machine has a single room and double room two, single room for tipping, two stents in the upper and lower vacuum chamber with a middle rear, wearing a double torsion spring axis by double torsion spring force balance, the opening angle of 45-75 degrees ranging. Double chamber for reciprocating, vacuum chamber is divided into two studios, vacuum chamber comprises four connecting rod support about displacement, the four connecting rods is fixed on the two axis, the long axis of a spring fork, two tension springs located in the lower frame, the upper part of the positioning in the spring fork, to balance the operation of gravity, two axis by two sets of bearing positioning, four upper connecting rods with miniature bearings, so the displacement is very easy, starting with vacuum pressure, back after gas can automatically open. The four connecting rods on the support displacement of the vacuum chamber, before and after each axis on the two, must be kept parallel to about two sets of connecting rods must remain relatively parallel, to ensure that the vacuum chamber remain parallel in about any position under the same vacuum chamber or cause the upper and lower vacuum chamber can't keep parallel, then the operation pressure increased significantly, even can not establish normal vacuum. Small treasure vacuum machine
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:What should we pay attention to when choosing the quantitative packing machine parts?
This is the best to find you buy packaging machine manufacturers, if not found, then you can find other factories to send your parts in the past, let others do for you.
Q:Gearbox mechanical parts, mechanical and electrical products?
Various aspects of marking, such as marking, have been fully standardized, and the commonly used zero (part) parts produced by professional factories
Q:As a mechanical component inspector, how do you improve the quality of your product?
In strict accordance with the requirements of the drawings to test, it is best to understand the parts, so that you know what size should be the key control parts are in accordance with its products in the role of design drawing effect on product play, as long as according to the requirements of the drawings focus intention to examine the quality of the products will be enhanced.
Q:Single vacuum packaging machine accessories, vacuum schedule, where to sell?
Hello, I Division specializing in the production of vacuum packaging machine, vacuum packaging machine accessories, good quality and low price
