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 “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:Can the nylon vacuum packing bag be high and low temperature with mechanical parts?
- 2 、 nylon vacuum packing bag has strong function:High temperature resistant to oil, humidity and resistance to 90 degrees Celsius, low temperature, freezing, quality preservation, freshness preservation and odor protection. It can be used in vacuum packing, aseptic packing and inflatable packing. [another special high temperature retort bag, >100 degrees]3 、 nylon vacuum packaging bags are of low cost:Compared to glass packaging, aluminum foil packaging and other plastic packaging, to achieve the same barrier effect, CO extrusion film has a greater advantage in cost. Due to the simplicity of the process, the cost of the film products produced can be reduced by 10-20% compared to dry composite films and other composite films
- 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:What is the definition of machining process specification?
- The machining process is the process of manufacturing or processing parts or parts, using the method of machining
- Q:What are the main parts of small vacuum machines?
- Hot pressing device and printing deviceThe device is installed in the vacuum chamber, there are usually two groups, a group of single room tipping activities arranged on the lower part of the vacuum chamber and double chamber reciprocating movable part is arranged on the upper part of the vacuum chamber, active device mainly consists of the following parts, heat sealing chamber is fixed on the upper vacuum box room two, head guide column and a spring reset device, hot press frame seat two head guide sleeve is sheathed on the guide pillar, heat sealing between the gas chamber and hot box frame seat is provided with a heat sealing chamber (also known as atmospheric vacuum chamber, said heat sealing chamber for small room heat) sealed air chamber is provided with plastic pipes, two head with a pinch clamp, rubber adhesive processing water is also useful a bicycle or a manpower vehicle tyre, the middle has a gas nozzle, hot pressing frame body with epoxy boards fixed pressing frame seat, two head belt rolling shaft, the winding shaft roll of Ni Cr alloy belt Tight positioning, covered with heat sealing cloth. The fixed part device mainly printing tape and tape box printing, printing glue used in silicone rubber processing, a plane with twill or straight lines, the other side is provided with a round or square hole, the silicon rubber used for processing of words or characters embedded in the park, in the seal and printed on the concave transparent production date. If need is needed in the color printing, printer ribbon. Small treasure vacuum machine
- Q:What are the components of mechanical equipment (automatic equipment)?
- Most of the mechanical parts have national standards, in the design as far as possible the use of standard parts, in the market is easy to find, also don't need to find all factory custom, non-standard parts customization, the price must not cheap. Of course, if it is a robot, it must be customized, and the material is not ordinary steel.
- Q:Air conditioning installed in the outer machine packaging, found a small part, please master to help see what is this?
- But the general maintenance plant is not balanced, and must be professional fan leaf manufacturers only, it may be difficult to improve, can only be purchased again fan leaf to replaceThe manufacturer of the shipment will have to make a warranty on this point. It may be difficult
- Q:A workshop needs to be packed with machine parts. 5 boxes are packed in 80
- 80 / 5=16 (a);340 / 16=21.25 (box) = 22 (box), 20 (box);Answer: 20 boxes can not be fully loaded
- 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:What kind of material is better for food packing box?
- In the plastic classification, the PET code number is 1, widely used: mainly for electronic and electrical equipment, including: electrical sockets, electronic connectors, rice cooker handle, TV deflection yoke, terminal taiwan
- Q:Gearbox mechanical parts, mechanical and electrical products?
- Such as threaded parts, keys, pins, rolling bearings and so on. The gear reducer is designed according to different speed reduction systems
