Product Description:

Type EWD-RL-J2 Elevator Weighing Device

System Introduction

DeclarationIn any case, our part is only responsible for the product own quality within the warranty period.

Description 1.State Indication - FlickeringAbout “Once per Second”

.Button Operation - PressPress and release soonHoldPress constantly

.Relay  - Keep the state of Picking-up in the period of system being unadjusted or fault

Main Features

 1. With the adoption of EWD-GA or EWD-GDH(that is type A load weight or Character “” type

   sensor)it can be easily installed at rope hitch

2. The system is of the structure of sensor with the domination of loading cell and controller, which can be installed at the car-side rope hitch

3. Directly outputting full-load or overload signal depending on the change of elevator car payload

4. Simple adjustment, high precision of measurement and quick and easy installation.

l Technical Specifications

Application Range

Q:Decocting machine for packaging liquid out of control, can not control how much liquid packaging
After excluding the first 2, still can not solve the problem, please check the circuit board above the solenoid valve SCR whether breakdown.
Q:What's the price difference between feed packer and organic fertilizer packing machine?
Organic fertilizer packaging machine and feed packaging machine is still the main difference between, in the mechanical structure, equipment selection, components and so on
Q:What is the principle of cleaning machine parts? How should the parts be kept after cleaning?
In the mechanical field assembly process, for some long-term storage or process reasons lead to rust, iron filings, oil pollution and other problems,Cleaning must be done. This is a relatively sophisticated process, if the cleaning is improper or not in place, it will affect the assembly quality and assembly schedule,Finally, the whole machine is running. Therefore, it is necessary to master the proper cleaning method and process
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: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:After the powder metallurgy parts are machined, how to prevent rust?
3, fine packaging: general is made of antirust paper or film, packaging finished powder metallurgy parts antirust oil immersion and dry, the powder metallurgy transport packaging, especially export packing is this way, such as piston ring, rust proof membrane can be more. But how specific matching, or exquisite.
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 kind of material is better for food packing box?
Breaker shell, switch, motor, fan shell instrument machinery parts, currency-counting machine parts, electric irons, electromagnetic stove oven accessories; automobile industry in the flow control valve, carburetor cover, window controller, pedal transmission, switchboard cover; mechanical industrial gear, vane, pulley, pump parts, in addition to a wheelchair car body and wheels, lamp shell, lighting device shell, drainage pipe joints, zipper, watch parts, spray parts.
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
Q:How is the vacuum packing machine assembled? How many parts?
Guarantee the quality and life of the whole machine. There are not many parts for vacuum packaging machines.
