With the development of economy and the improvement of living standard, people's demand for food quality is also getting higher and higher. As the staple food of most people in the south, the quality of milled rice has increasingly become an important indicator of consumer choice. For the general consumer, what can be spelled out is basically some apparent factors, so the color of rice is closely related to commodity sales. Rice color sorter machine can greatly improve the color of rice. 
Rice color sorter uses advanced photoelectric technology to specially remove discoloration. During the storage of rice, some grains will deteriorate and become yellow grains due to fever and other reasons. Yellow-grained rice contains harmful ingredients to human body. The finished rice contains more goods than rice, which not only affects the commodity value of rice, but also the health of consumers. It should be removed as far as possible. Because there is no difference in general physical characteristics between yellow rice and normal white rice, it can not be removed by common ship clearance method. Only by the difference of color and reflectivity between yellow rice and white rice can it be used to eliminate by photoelectric colorimetric method and equipment. The rice color sorter can also eliminate the discoloration of small glass and coal particles mixed in rice by using the difference of color.

LINPRO designs and provides most suitable color sorting solution according to client’s different needs, creates new value for them.RFQ today!

Silicone rubber waterproof mastic sealant is a non-shaped sealing material composed of organopolysiloxane as the main agent, with vulcanizing agent, vulcanization accelerator, reinforcing filler and pigment added. According to the use, it can be divided into F type and G type. Type F is used for building joints while Type G is used for mounting glass. According to the fluidity, it can be divided into N type and L type. The N type is non-sagging type while the L type is self-leveling type. According to different vulcanizing agents, silicone rubber sealants can be divided into acetic acid type, ketone oxime type, alcohol type, amine type and amide type. In general, high modulus silicone rubber building sealant uses two types of vulcanization systems: acetic acid type and alcohol type; medium modulus silicone rubber building sealant adopts alcohol type vulcanization system; low modulus silicone rubber construction sealant adopts amide type vulcanization system.

The waterproof principle of silicone rubber foam sealing strip: silicone rubber sealing strip will elastically deform under pressure, so that the gap between the contact interface and the sealing strip is filled and generates a rebounding force, so that the contact surface and the foam sealing strip produce friction. When the sealing strip itself does not leak and when the friction force and the rebounding force are greater than the internal pressure or the external pressure of the sealed medium, the sealing material does not leak due to deformation or displacement, and vice versa.

Silicone rubber waterproof polymer mastic sealant includes:

Deacetic Acid Type

General-purpose application range: glass joints, frame gaps, glass suspension, glass installation in glass sinks (showcases, shop windows)

Highly transparent application range: seams that require transparency

Anti-mildew application range: sealing of bathroom, countertop, washroom, sanitary ware

The terminal has three main parts: matching part, transition part and crimping part. The crimping part is the only part whose design is affected by the crimping process. Here are some of the most common problems and corrective actions.

1. Conductor crimping height is too small or too large

Solution: adjust the height of conductor crimping on the crimper. Use vernier calliper or micrometre to check whether the crimping height is within the specified range, and recheck according to the required frequency during the operation to maintain the correct crimping height.

2. The insulation crimping area is too small or too large

Most types of crimping tools can adjust the insulation crimp height. The correct adjustment allows the terminal to clamp the insulation at least 180 degrees without piercing the insulation. When the outer diameter of the insulating crimp of the terminal is close to the outer diameter of the cable insulation, the best method is IDT technology.

3. Loose core

Solution: fold up the cable again to form a bundle, and then insert it into the terminal for crimping. If the removal of the insulation from the cable is a separate operation, the cores may be inadvertently separated during handling or bunching. Use half stripping and keep the insulation removed so that the insulation is not completely removed from the cable until the terminal is ready to be crimped to the cable, which helps to minimize the core looseness.

4. Too short stripping length

The stripping length of the cable is too short, and the distance out of the front of the conductor crimping area cannot obtain the required outer diameter of the cable. The solution is simple: increase the stripping length of the stripping equipment to the specified value of the terminal.

5. The cable is inserted too deep

Solution: make sure that no excessive force is used to insert the cable into the crimper to make it over-voltage the cable stop of the crimper, or adjust the position of the cable stop to correctly position the stripped cable axially.

6. Over bending

Solution: adjust the position of the limit pin on the crimper. This pin is located in the crimper and contacts the joint area of the terminal when crimping the cable in the crimping area. During the crimping process, a large amount of metal at one end of the terminal (in the crimping area) moves. Such a large force tends to force the front of the terminal up unless limited by a suitable "limit pin."

7. Crimping too far forward

The reason for this problem is that the terminal and the metal strip (the metal strip connected by the terminal when you receive the goods from the manufacturer) are not in the correct position relative to the crimper. Just loosen the base plate of the interchangeable tool, and then realign the crimper to solve the problem.

8. Too small bell mouth

The correct size of the bell mouth is 2 times the thickness of the terminal material. In essence, it affects the performance of the terminal. If the bell mouth is missing or the thickness of the terminal material is less, there is a risk of cutting the wire core. Reduced core retention reduces termination strength. To correct the problem, make sure that the punch on the crimping device is correctly aligned with the base.

9. The bell mouth is too large

If the bell mouth is too large, the total contact area between the terminal crimping area and the cable will be reduced. The smaller the contact surface between the cable and the terminal, the smaller the cable drawing force. If the crimp height is correct, it may be caused by tool wear and should be replaced.

10. Tail material is too long

Solution: adjust the feeding plate on the crimper to make the terminal correctly centred in the crimper. Another sign that the terminals are not properly centred is that the bellmouth is not properly formed. This occurs because the bell mouth has a spatial relationship with the tool of the tailings.

11. Installation of an intelligent pressure management system

The intelligent pressure management system can monitor the operation of the terminal machine in real-time, find out the abnormal pressure in time, and adjust and maintain the equipment in time as described above! In this way, the machine has been in a good state of operation, thus indirectly reducing the production of defective products!

However, it should be noted that although the pressure management is very sensitive and can be used to evaluate the operation of the machine, in normal production, the tolerance is usually set to a large extent to reduce the number of alarms, so the various adverse conditions described above are basically impossible to detect all without leakage.

The intelligent pressure management system can detect 100% of the fatal problems such as all the core wires are cut off, all the glue is wrapped, and the terminals are deformed. These fatal problems cause great pressure changes. It is the main significance to prevent these fatal problems from flowing to customers!

The 36-meter concrete pump truck is an excellent medium and short arm pump truck, which is made after HBT towing pump, HBC on-board pump and HGY hydraulic concrete dispenser. It is a high-efficiency, integrating running, pumping and cloth.

At present, some advanced manufacturers have begun to apply some special processing methods. China is in a critical period of national economic development. But China's machinery manufacturing technology is not advanced. To narrow the gap, we must catch up with the world's advanced technology. only in this way, can we adapt to the fierce market competition, thus promoting the sustainable and rapid development of the national economy. The core of market competition is to promote production efficiency.

The 36-meter concrete pump has less power consumption, higher capacity and better measuring capacity. A pair of compressors rotates along a specially made rubber tube, flattening the tube and restoring it to its original state under the force of its own elasticity and side conductors. At this time, a high vacuum is generated in the tube to suck the material into the tube cavity. Then, the material is expelled from the pipe under the subsequent pressure compression. So over and over again, the material is sucked in and expelled. The pumping system is powered by a motor or diesel engine, which makes the rotating structure simple, thus shortening the rotating chain, improving the rotating efficiency, reducing the failure rate and prolonging the service life.

In the construction of fine stone concrete or mortar backfill layer in the floor heating project, the construction method of fine stone 36 meter concrete pump is not easy to damage the floor heating pipeline and can greatly improve the construction efficiency and reduce the labor intensity of workers compared with the construction method of elevator. In recent years, the fine stone equipt concrete has been widely used in the transfer of fine stone concrete or mortar on the wall and ground of high-rise buildings.

WHAT'S THE DIFFERENCE AMONG WELD NECK FLANGES, SOCKET WELD FLANGES, SLIP ON FLANGES?

Weld neck flanges, slip on flanges, socket weld flanges have different production standards, different applicable occasions. In addition, weld neck flange is the interface end pipe diameter and wall thickness is the same as the pipe to be welded.

Slip on flange is the joint being processed to a concave table a little larger than the pipe outside diameter, pipe inserted in the inside for welding. Weld neck flange has better welding performance and less corrosion.

Slip on flanges are generally used for low and medium pressure pipelines, weld neck flanges are used for connection of middle and high pressure pipelines, generally at least pn2.5mpa. Weld neck flanges are used to reduce stress concentration.

Features of various forged flanges:

Socket welding flange is suitable for connecting pipe with small diameter, high pressure and high temperature.

Slip on flange is the same with weld neck flange, has a groove cut in the lug and the pipe inserted into it for welding.

Socket weld flange has no boss, directly cut a groove in the flange body, just like a hole in the blind flange, and then cut a groove.

Slip on flange is slightly better than socket weld flange in performance.

Magnetic flux leakage test refers to the formation of a leakage magnetic field on the surface of a test piece after it is magnetized due to defects on the surface or near-surface of the test piece. People can detect defects by detecting changes in the leakage magnetic field.

Briefly describe the magnetization of ferromagnetic components. In the magnetic non-destructive testing, magnetization is the first step to realize the detection, which determines whether the leakage magnetic field signal can be generated, and also affects the performance characteristics of the detection signal and the structural characteristics of the detection device.  Like magnetic particle inspection, magnetization is achieved by a magnetizer, including both a magnetic source and a magnetic circuit.  The magnetic source and the magnetic circuit change depending on the structure of the member to be tested.

What kind of magnetization can be divided into several categories? The magnetization methods can be generally divided into five categories, namely, alternating current magnetization mode, direct current magnetization mode, permanent magnet magnetization mode, composite magnetization mode, and integrated magnetization method.

What are the characteristics of magnetic flux leakage equipment technology?

Because mfl equipment uses magnetic sensors to detect defects, compared with magnetic powder, penetration and other methods, it has the following advantages:

1. It is easy to realize automation. The computer judges the presence or absence of defects based on the detected signals.

2. The fundamentally high detection reliability can solve the influence of human factors in the magnetic powder and osmosis method, and has high detection reliability.  

3. can achieve preliminary quantification of defects.  In the range of wall thicknesses up to 30 mm, the inner and outer wall defects can be detected simultaneously.  In the detection of the pipeline, 5 high-efficiency, pollution-free automated inspection can achieve high detection efficiency.

BKN's portable magnetic flux leakage testing equipment are capable of detecting workpieces efficiently and accurately.

The difference between the two balancing valves is that the thermostatic balancing valve
manually adjusts the opening degree of the thermostat valve, while the auto balancing valve automatically adjusts the opening degree of the thermostat valve by using temperature sensors.

Thermostatic balancing valve (referred to as constant temperature valve) is an energy-saving product. The principle is to control the temperature of the valve by using the temperature sensor in the temperature control valve head. When the room temperature rises, the temperature sensor expands due to thermal expansion and compresses the stem to make the valve close small. When the room temperature drops, the temperature sensor shrinks due to cooling, and the stem springs back to open the valve. Therefore, when the room has other auxiliary heat sources (sunlight, other heaters) and the room temperature is higher than the set temperature, the valve automatically closes down, the water intake of the radiator decreases, ultimately saving the heat of heating.
The setting temperature of the auto balancing valve can be adjusted artificially. The constant temperature valve will automatically control and adjust the water quantity of the radiator according to the set requirements, so as to achieve the purpose of controlling the indoor temperature. Temperature control in user's room is realized by constant temperature control valve of radiator. The constant temperature control valve of radiator is composed of a constant temperature controller, a flow regulating valve and a pair of connectors. The core component of the constant temperature controller is the sensor unit, namely the temperature package. The temperature chamber can induce the volume change caused by the change of ambient temperature, drive the valve core to produce displacement, and then adjust the water quantity of the radiator to change the heat dissipation of the radiator.

到美国留学如果被签证耽搁了，可真是得不偿失，今天求真教育小编就给大家整理了美国签证辅导攻略，希望对大家有所帮助。

　　1. 按清单备好材料

　　I20 表格原件

　　SEVIS fee 收据

　　DS160 签证申请表确认页

　　面签预约确认页 & 交费收据

　　护照 & 身份证

　　签证照片

　　学校录取信、奖学金 offer

　　财力证明：存款证明/存单/存折、房产

　　出资人相关证明：父母收入证明（家里的公司，提供营业执照盖章的复印件，股权分配等文件盖章复印件），全家户口本/出生证

　　成绩单 & 学历证明

　　项目介绍，导师简历

　　学习计划，自己的简历

　　2. 充分了解签证官关注的问题，提前做好练习

　　一定要明确赴美的唯一目的是学习

　　明确学习完成后是否会回国

　　是否有足够资金支付在美费用

　　其他：是否有能力在美国做全日制学生

　　（通过签证后，学生会收到签证官给的卡片）

　　一些小 tips：

　　不管是作为学术型还是作为职业型硕士都准备一下 study plan，用 ps 改一下也行。不要太强调自己家庭收入和家庭关系，只要写好学习计划即可，千万不要提到日后要移民美国拿永居。

　　签证简历不要照搬申请用的简历，一些敏感信息（如去过非洲疫情区、做过敏感专业科研）可以删掉。

　　如果你的项目还没有为你配备 advisor，你可以把项目的 director 或和你经历相关的教授作为潜在 advisor 信息，写在相关的签证申请材料里。

　　提供的资金证明不要超出规定的学校学费和生活费太多，或者根本很勉强才能维持研究生的学习和生活，超过很多和不及，都会造成动机不纯的现象，造成拒签。

如果是美本、美硕，申到其他美国学校要回国换 F-1 签证，之前学校的 I-20、offerletter 都带着，签证官可能要看。
