The composition of automation equipment component

Automation equipment most generally have the following parts: 1.Indicator light: general mostly are light-emitting diodes (leds), long life, neon bulb and bulb life is short, job is an alternating current and direct current voltage. 2.Button and urgent stop switch: button is often used in pneumatic and control keys, such as temporary, also some kinds of rotating button control; Scram button are usually red and yellow. 3.Fuse: mainly protection circuit, when the voltage and current is too large, can fuse protection circuit. 4.Switch and power switch: control buttons. 5.Circuit breaker: mainly is the restoration of short circuit protection, instantaneous short circuit occurs when the circuit and electric device and instantaneous large current, automatic trip, protection device for posterior. 6.Ac contactor: mainly used to control equipment of the main circuit of the power outages, general electric current is larger. To control power in contact. 7Intermediate relay, and have the same ac contactor is a function of the protection circuit. 8.Hot relay: thermal element, is mainly used for the protection of the equipment temperature, automatic short circuit protection at the back of the line. 9.Delay protection: general electric power delay and delay. 10.Knife switch: main artificial broken electronic control and control, generally speaking, there are two or three knife. 11.The leakage switch: mainly used for protection of personal safety, single-phase and three-phase residual current switch. Hope the above comments in you use, you are welcome to inquire.

6 influence the use of automation equipment

Factors affecting the operation of automation equipment has the following six factors: 1.Equipment failure loss This is a sudden or chronic time loss caused by fault happened is due to time loss and reduce the total production of direct losses. 2.Equipment production loss adjustment(or unscheduled time loss) This is accompanied by the planned production downtime loss, design is the production adjustment time outside of the loss. 3.Equipment sudden stop and the idling loss Equipment made a surprise stop and fault, the device because of a temporary stop loss is called sudden stop loss. In order to reduce equipment sudden stop, and to analyze various phenomena and well thoroughly eliminate small defects, to achieve the goal of a sudden stop is zero. Especially in the implementation of unmanned operation of the equipment, a sudden stop to zero is the necessary condition. 4.Loss of speed Is the equipment does not meet design speed and actual production capacity loss. 5.Scrap defect repair damage Caused by the waste defective and needs to be fixed production losses, say waste defect repair damage. 6.To start construction equipment loss Is loss occurred at the start of production operation, the operation from the beginning to the product fine production so far this time loss. Hope the above comments in you use, you are welcome to inquire.

Choose a few skill points of pig feed

1、Definition: Pig feed is usually composed of protein feed, energy feed, roughage silage feeding materials, minerals, green feed, feed and feed additives; By category: full price, concentrates and premix. 2、Type: Pig has a variety of commonly used feed, according to the nutrition into energy feed, protein feed, roughage, green feed, silage feeding materials, mineral eight kinds of feed and feed additives. 3、About hormone: now basically has added a variety of hormones and antibiotics in pig feed, in order to make the pig meat fast and long lean lean, take a lot of hormone and clenbuterol in feed, in order to pig skin brightness, to add urea and arsenic preparation, in order to pig don't get sick, to add antibiotics and so on. 4、Note: （1）Selection of raw material variety as much as possible raw material variety can have the complementary role of nutrients, but must pay attention to the pig. Nutrient use efficiency in the raw material. （2）The quality of feed ingredients to conform to the standard purchasing raw materials can be in accordance with the national standard, avoid by all means purchasing cheap and inferior raw material. （3）As far as possible the use of local cheap feed raw materials The local feed raw material resources is not the same, some cheap feed ingredients such as rice bran, tofu, can take advantage of, in order to reduce production cost. （4）Feed raw material supply is plentiful For some sometimes no raw material, it is best to avoid using, often because of change the raw material, can cause stress to the pigs. （5）Pay attention to the palatability of feed ingredients Although some raw materials are very cheap, but it isn't palatability, attention should be paid to limit the amount of such materials. On the contrary, for those who are very good palatability raw material, also want to consider to feed restriction, to prevent overeating and digestive problems. （6）Strictly according to the breed standard design recipes, conceptions of avoid by all means Feeding standard were made according to the results of feeding trials, more authoritative standards include the NRC standard, British standard of ARC and the national standard of our country. （7）Mixed evenly Some add less of the raw materials have to be premixed first, and then wait to be added to the aniseed mixed in
