The maintenance knowledge of office furniture is believed to have a certain understanding of the performance and nursing knowledge of the products in the long-term, but if there is any problem with the sheet and materials of the office furniture, it is not necessarily I understand that Xiaobian has been in the factory for many years and found that there are four major problems in the production process of wood furniture. 1. Drying treatment is not in place. The drying process of Shenzhen furniture wood is a complicated process, and the treatment is good or bad. The quality of wooden office furniture has a greater impact. Generally, high-quality wooden office furniture will be dried for a long time, and then manually dehumidified and dried. The drying process of different materials is different. If there is no advanced equipment, large place and skilled operation technology, even after drying. Processing, and ultimately there will be quality problems.
2. The wooden office furniture that is not tightly sealed and dried. If the sealing is not strict and the water is eroded twice, it will be deformed and expanded. Therefore, the wooden office furniture should not be exposed to the air in the decoration construction site. If it is too long, it should be processed in time, otherwise the above quality problems will occur.
3. Quality is not good. In the decoration process of Shenzhen furniture, it is also crucial to choose wooden office furniture. Under normal circumstances, when consumers choose wooden office furniture, it is best to choose a manufacturer with high reputation and good reflection, because the quality of the products of regular wooden office furniture manufacturers will be guaranteed. In addition to this, you should also see if the texture of the wooden office furniture is clear, and whether there are traces of repairs such as insect eyes and cracks.
4. The water content is not up to standard. It should be seen whether the work of the wooden office furniture meets certain standards, for example, whether the thickness and width are consistent, and whether the hand is flat or not. In fact, the most important thing when choosing wooden office furniture is to look at the moisture content of the material itself. Generally, the moisture content of wooden office furniture in the northwest region should be controlled at 8%-10%. If it is larger or smaller than this data, the wooden furniture will be The above problem will occur. When purchasing wooden office furniture, you should ask the dealer for inspection report or conduct on-site inspection.

High Speed Door Motor And Control Box
Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.
About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.
About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: ＜16 ㎡; Daily operating time: ＞2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.
The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.
System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.
Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.
The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.
Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.
Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.
High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.
Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
