>>>Sanitary ware installation process
For each family, sanitary ware is indispensable. Judging whether the sanitary ware brand is good or bad depends on the following aspects:
The first is the blank: the quality of the blank directly determines the water permeability of the ceramic. At present, the firing process of ceramics has been greatly improved. Most brands, including some low-end brands, use high-temperature pottery fired at 800 degrees or more. In the early years, ceramic ware that used to be used in three to two years has become a mess. Already rare, now four or five hundred toilets do not have big problems for three or five years. But the same high-temperature pottery, the difference between grades is also very obvious, the "high-temperature tunnel kiln" length directly determines the texture of the ceramic, the longer the tunnel, the longer the ceramic from heating to cooling, the temperature changes during the firing process is small, the product It is not easy to crack, and it is resistant to sudden cooling and heat. The "high-temperature tunnel kiln" is short. The process from high temperature to cold sensation is short, and the burnt-out ceramic texture is relatively brittle and easily cracked. The cost of high-temperature tunnels is very high. The average cost per meter is nearly 150,000 yuan, so some small-scale manufacturers directly cool outside the kiln, and the quality difference is even greater. In addition, only the furnace is large enough to burn a high water tank, save water and clean it.
The second is to look at the glaze: the glaze brand, the thickness of the glaze layer, and the firing process all directly determine the effect of the glazed sanitary ware. The imported glaze is used. The glaze is thick and the surface of the sanitary ware is flat and delicate, full of texture, and crystal clear. It's very comfortable to go up. And self-cleaning ability, low water permeability. The sloping treatment is also applied to the sewer pipes of the middle-to-high grade sanitary ware and the inner wall of the water tank. This is very important to prevent the toilet from being dirty. However, this process is very difficult. The domestic brand is rarely available, and whether or not the sewer pipe is used for glazing is important. An important sign to determine the grade of sanitary ware.
The third is to look at accessories: traditional copper water parts, floating ball irrigation have been eliminated, the current good water parts are imported PVC materials, vacuum irrigation technology, anti-corrosion anti-rust performance and leak-proof performance have greatly improved. The brand-name sanitary wares are supplied by professional manufacturers. Fourth, look at the overall shape. A good sanitary ware should not only look beautiful, but also be ergonomic and comfortable to use. Manufacturers' molds, equipment and design capabilities are the deciding factors. High-level manufacturers generally use imported molds.

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.
