Home renovation of the groundwork should be considered the basis for home improvement. Many people do not understand the acceptance of ground engineering. In fact, there are many types of ground engineering. At present, there are two types of floor ground and wooden floor.
Acceptance plate ground first depends on whether the type of plate in the surface layer (the surface layer that can be seen) meets the design requirements.
The surface layer and the base layer should be firmly bonded without hollowing. Hollowing is a common disease in the project. Simply speaking, there is an air gap between the surface loading and unloading material and the base layer, which leads to structural problems. The method of checking this problem is relatively simple. To find a small hammer, tap it, listen to the sound, and empty the drum if the voice is empty.
Secondly, it is necessary to check that the surface of the plate should be clean, the pattern is clear, the color and luster are uniform, the interface is uniform, the periphery is straight, and there is no phenomenon of cracks and defects;
Third, the floor slope of kitchen toilets must meet the design requirements, and must not be flooded or accumulated water.
Fourth, the laying surface of the baseboard should be clean, the joints should be even and even, and the joints should be firm. The thickness of the wall should be suitable. A hammer can be used to tap;
5. The material and dimensions of the edging (copper wire, etc.) adjacent to the surface meet the design requirements, and the corners are neat and smooth;
Sixth, using a 2 meter ruler to check the surface flatness, the allowable deviation of the marble plate is 1 mm, and the allowable deviation of the whole body brick is 2 mm;
Pull 5 meters to check the seam line. The allowable deviation of straightness is 2mm. The marble is 3mm. The baseboard is straight. The allowable deviation is 1mm. The bricks are 3mm. The width of the plate gap is not more than marble. 1 mm, brick body not more than 2 mm;
Check the woody ground mainly to see the following points:
First, wood joists, wool floors, and stumps must be treated with anti-corrosion treatment. The installation must be firm and straight. The spacing meets the design requirements and the foot can be checked;
Second, the wood surface must be nailed firmly without loosening, no hollowing, and can be tapped with a small hammer to check;
Thirdly, the surface layer of the wood is polished and polished, with no scars, blemishes, and furrows. The pattern is clear, the gap is tight, and the joint is staggered and glued without overflow;
Fourth, the wooden skirting seam tightly smooth surface, the thickness of the wall is the same;
Fifth, use a 2-meter ruler to check the surface flatness, allowing a deviation of 2 mm.
Pull the surface of the 5 meter line to allow the seam straightness to be allowed to deviate by 3 mm, the allowable deviation of the straight line on the baseboard line is 3 mm, and the gap width is not more than 0.5 mm.

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.
