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.

First, mineral nutrient elements 1. Urea. The 0.2%-0.3% urea solution was sprayed once before flowering, full bloom, and 3 weeks after flowering, which had a good effect on improving the fruit setting rate of fruit trees.
2. Rare earth. Spraying rare earth can increase the fruit setting rate, and spray 500ppm solution before and during flowering. However, be careful not to mix with alkaline fertilizers or alkaline pesticides.
3. Boron fertilizer. Spraying 0.2%-0.3% borax or 0.1%-0.2% boric acid in the fruit buds during the expansion period, full bloom period and 3 weeks after flowering can increase the fruit setting rate by 15%-40%, and the boron fertilizer can be mixed with urea.
4. Zinc sulfate. The fruit tree is sprayed with 0.1% zinc sulfate solution (preferably mixed with 0.1% boric acid) before and during flowering, which can significantly increase the fruit setting rate.
5. Molybdenum fertilizer (sodium molybdate, ammonium molybdate). The effect of spraying molybdenum on the marshal's apple flowering period is very obvious. According to the test, the red star apple is sprayed with 0.3% sodium molybdate solution during the flowering period, and the fruit setting rate can be increased by 107.4%.
6. Potassium dihydrogen phosphate. During the flowering period of Li Shu, 0.2%-0.3% potassium dihydrogen phosphate solution was sprayed, which significantly increased the fruit setting rate.
Second, growth regulators 1. Gibberellin. Jujube tree spraying 10-15 mg / liter of gibberellin, the fruit set rate can be increased by 59%; hawthorn flower spray 40-50 mg / liter of gibberellin, fruit set rate can be increased by 30% -50%; In the first l-2 days, the inflorescence or inflorescence was sprayed at a concentration of 100 mg/L. After the flower was grown, the fruit was sprayed once when the soybean was large, which allowed the coreless rate to reach 100%, and increased the weight of the fruit. The amount of sugar and the degree of coloration improve the quality of the fruit.
2. Cytokinin. Spray 800 times cytokinin solution before and after the flowering period, which can significantly increase the fruit setting rate and increase the sugar content of the fruit.
3. Longer than (B9). During the full bloom period of the Kyoho grape and 0.2%-0.4% longer than the long-term aqueous solution in the two weeks after flowering, it can make the grain large, uniform, early maturing and high yield. If mixed with 0.3% longer than 100 mg/L sodium bisulfite solution during the full bloom of Kyoho grape, the effect of preserving the fruit is very significant. After the strawberry flower is sprayed 2-3 times for 0.10%-0.15% than the long-term solution, the result can be promoted and the fruit can be enlarged.
4. Paclobutrazol. Spraying 500 mg/L, 100 mg/L, 200 mg/L paclobutrazol at 8-12 tablets in front of the flowering peaks of Kyoho grape, and reducing the growth of new shoots by 2/5, and inhibiting The growth of the secondary shoots can reduce fruit drop, improve fruit quality and yield, and benefit the next year's high yield.
5. Fruit shape agent. In the flowering period, the flowers and receptacles of the 50-g/L spray Marshal's apples can increase the fruit shape index, and the five-edges are obvious, which improves the appearance quality.
Third, foliar nutrient photosynthetic agents and liquid fertilizers 1. phytoalexin. In the red Fuji flower bud stage, young fruit stage spray 600 times, 700 times phytoalexin, can increase the fruit set rate.
2. Foliage treasure. Spraying the leaf noodles in the flowering and young fruit stages of the fruit trees can preserve the flowers and preserve the fruit, increasing the yield by 20%-30%. When used, each pair of water is 40-50 kg, which can be mixed with acidic pesticides. If a small amount of urea is added, the effect is more obvious.
3. Photosynthetic micro-fertilizer. Red Fuji apples began to spray photosynthetic micro-fertilizer 3 weeks after the flowering period, and even sprayed 3 times, each time interval 15 days, the fruit setting rate can be increased by 87.7%.
Fruit tree flowering spray fertilizer technology
The spraying of some nutrient-containing nutrients on the foliage of fruit trees can increase the fruit setting rate of fruit trees, improve the quality of fruits, and increase the yield of fruit trees.
