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.

1. According to the growth of tomatoes, the type of nutrition should be determined: Generally speaking, in the early stage, the growth of the plants is relatively strong, and it is easy to grow, and the leaf nutrition that promotes the growth of stems and leaves should be used less. Potassium dihydrogen phosphate, compound fertilizer, etc. can be used. At the peak of the period, the growth potential of the plant began to weaken. The leaf nutrients that promote the growth of stems and leaves should be used to promote the leaf protection. Urea, sugar and Dayuan No.1, Jiagean and other leaf-specific nutrient solutions can be used.
2. According to the weather conditions, the type of nutrition should be determined: the snowy weather, the lack of light in the greenhouse, the poor photosynthesis, the insufficient supply of sugar in the tomatoes, and the better effect of spraying sugar on the leaves.
3. Spraying calcium fertilizer in time: The growth of tomato fruit requires more calcium. When the soil is insufficient for calcium, the fruit is prone to umbilical rot. Therefore, in the tomato fruiting period, it is recommended to spray calcium fertilizer such as calcium chloride, superphosphate, amino acid calcium and calcium supplement to meet the needs of tomatoes for calcium.
4. The interval between fertilization of tomato leaves should be appropriate: the suitable interval for fertilization of tomato leaves is 5-7 days. The interval between inorganic fertilizers in which foliar spray is easy to produce fertilizer should be longer, generally not shorter than 7 days, and the spraying time of organic nutrition can be appropriately shorter, generally about 5 days.
5. Foliar fertilization of tomatoes should be combined with disease prevention: Foliar fertilization in winter and spring seasons in greenhouses will result in a significant increase in air humidity in the protected areas, which may cause tomato disease. Therefore, even the number of fertilizers sprayed on the cloudy leaves is less. When applying fertilizer, add protective fungicides such as Antaisheng and DuPont Yibao, and short-time ventilation after fertilization to reduce the incidence.
6. Improper use of foliar fertilizer: When wounded leaves occur, rinse the leaves with clean water, rinse off excess fertilizer, and increase the water content of the leaves to alleviate the damage of the leaves. When the soil water content is insufficient, watering is also required to increase the water content in the plant and reduce the concentration of the fertilizer in the stems and leaves.
Greenhouse tomato leaf fertilization attention problem
Foliar fertilization of greenhouse tomatoes generally begins after fruit set and until the plants are pulled, playing an important role in the formation of tomato yield. Foliar fertilization should adopt different management methods in time for different situations. The following points should be noted:
