Water treatment systems manufacturer by Ocpuritech? Water sources like groundwater, surface water, municipal and industrial waste water treated suitably, as well as liquid manure stored in lagoons on the site in large dairy and pig operations, are traditionally used for agricultural applications. In compliance with storage, treatment and management standards, dairy manure and CAFO are the main problems faced by these segments of the agricultural producers market.There are also water treatment problems and regulations existed in the market segment of vegetable and fruit processors that involve the washing of vegetables / fruits and the recycling of waste water that must be addressed. See even more details at reverse osmosis systems.

Good quality Ocpuritech water treatment systems can help you to save money and time. Water-treatment isn’t any process that improves the quality of water to make it more acceptable for a particular end-use. The processes involved with removing the contaminants include physical procedures like filtration and settling. The ending use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other applications, for example being directly returned into the surroundings.

With the tense water resources and rising prices, the large amount of water used for printing and dyeing, and the large amount of processed reclaimed water, it has raised the demand for water and wastewater control, the situation of water use by printing and dyeing companies has become increasingly serious, and the limited water resources have also determined that the printing and dyeing industry should concentrate on circular economy development, so vigorously developing water treatment equipment is a wise choice for the long term development. The application of water treatment equipment in food processing is one of the major uses of water treatment equipment. Everybody knows that water treatment equipment is the use of deionized water treatment equipment physical and chemical methods to treat raw water which doesn’t meet the requirements of miscellaneous water treatment equipment ,so that the purified water meet the standards . Nowadays, the water environment has attracted more and more attention from people.

Our CEO Carrie once traveled abroad, she inadvertently saw the use of water in Africa is seriously polluted, drinking water comes from river with severe pollution and used by people directly. She thought other areas may also encounter water pollution problems and people from all over the world may be eager to get clean and safe water resources.

In order to choose the lowest onnage specifiction,itis best to plan for a bening radus larger than the thickness of the material, and use the free bending method as much as posible When the bending radius is large, it often does not affect the quality of the finished part and its future use. Bending accuracy requirements are a factor that needs to be carefully considered. It is this factor that determines the need to consider a CNC bending machine or a manual bending machine. If the bending accuracy is required to be ±1 and cannot be changed, the CNC machine must be focused.

Synchronization system: The machine consists of a mechanical synchronization mechanism composed of torsion shats, wingarms, jont bearing, ec, with simple structure, stable ano reliable performance, and high synchronization accuracy. The mechanical stop is adjusted by the motor, and the numerical control system controls the value; Stopper mechanism: The stopper is driven by a motor, and the two screw rods are driven to move synchronously through a chain operation. The numerical controlsystem controls the size of the stopper.

As far as free bending is concerned, punch and die are procese at 85 or les (saler i better). When using this set of molds, pay attention to the ga beteen the male mold and the female mold at the bottom of the stroke, and the excessive bending that is sufficient to compensate for the springback and keep the material at about 90°. Generally, the springback angle of the free bending die on the new bending machine is s2, and the bending radis is equa to 0.156 times the opening distance of the die. For the bending of bottomed concave molds, the mold angle is generally 86 ~ 90°. At the bottom of the stroke, there should be a gap slightly larger than the thickness of the material between the male and female molds. The forming angle is improved because the bottomed die has a larger bending tonnage (about 4 times that of free bending), which reduces the stress that usually causes springback in the bending radius.

The reason for this is the significantly lower modulus of elasticity of aluminum compared to stel. However, i ore to realise reaterdegrees o defration, sale straightenig rolls must be used. With high-strength steels, on the other hand, a conflict of objectives arises. On the one hand, their high yield strengths require enormous forming forces and torques; on the other hand, small straightening rll diameters are als ned here to ahie asufficent egeo p lstificaton.The straightening o both aluminum and high-strength steels therefore requires a forming geometry adapted to the respective product. This is essentially determined by the number, diameter and spacing of the straightening rolls. See more info on pressmachine-world.com.

Level gauge wholesale China? Mechanical interference, the so-called mechanical interference, means that some components inside the radar level sensor will also vibrate due to the large-scale vibration or impact of the external machine, and even undergo displacement and deformation, which may also cause the pointer of the instrument head to loosen and cause measurement. error. In this case, we usually use spacers, shock springs, etc. to cushion the shock. Find more details on level switch manufacturer. Suitable for chemical industry, petroleum industry, metallurgical industry, water conservancy and electronic industry, etc.

The installation of the liquid level gauge should be away from the inlet, outlet, eddy current or protrusions on the inner wall to avoid the interference of electromagnetic waves and affect the measurement. When installing the guided wave radar, make sure that the diameter of the short pipe at the flange connection is greater than the height of the short pipe, otherwise the cable will contact the short pipe wall due to shaking, and the liquid level cannot be measured accurately. How to choose a model, in the final analysis, you still need to understand your own working conditions and the characteristics of different instruments, and judge whether the two match, so that you can get twice the result with half the effort.Want to know about ultrasonic flow meter advantages and disadvantages, click here.

Measurement accuracy, the accuracy of ordinary radar is generally ±10mm, and the accuracy of precision radar is ±3mm. Selection according to the actual needs of production. Range, according to actual needs, choose the antenna size. Note that the actual range is reduced in complex environments. Antenna type and antenna size, the larger the antenna size, the larger the measured range and the stronger the anti-interference ability. The antenna types of radar level gauge are rod type, bell mouth type, paraboloid and so on.

There is AC interference and the voltage is high. For example, for the radar level meter used in the production line, the power supply requirement is 24VDC (typical value), but in the on-site measurement, it is found that the power supply is displayed as 27.2V, which is significantly higher than 24VDC, resulting in a large measurement result and even a radar level meter. crash phenomenon. The installation position of the radar level meter is incorrect, which leads to deviations in the measurement. For example, the accumulation of aggregates in the transfer bin is a “mountain”-shaped cone, but only one radar level meter is installed near the discharge port of the return belt. , the installation position is too close to the discharge opening of the return belt, and at the same time, it is too far from the discharge opening of the feeding belt on both sides. Just below the radar level meter is the drop point of the return belt. If the distance is too close, the aggregate in the falling process will interfere with the radar level meter and form false reflections.

Side length of bending part: Assumin tht it is bent 90° longa 5 10-oot 1-gauge low-carbon steel plate, the bending machin mu apla ditonal 5 tos of pressr to lifthe sel plae u, ad the operator must be prepared for the 280-pound straight edge drop. Several strong workers or even a crane may be required to manufacture this part. Operators of bending machnes oteneed to bend long-side parts without realizing how strenuous their work is.

Hydraulic press brake machines are divided ito manual bending machines, hydraulic bending machines and CNC bending machines. Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. According to the synchronization method, hydraulic bending machines can be divided into: torsion axis synchronization, machine-hydraulic synchronization, and electro-hydraulic synchronization.According to the movement mode, hydraulic bending machine can be divided into up-moving typ and down-moving type.

Carefully consider the material grade and the maximum processing thickness and lengh. If most of the work is lowcarbon steel with a thickness of 16 gauge and a maximumlengh of 10 feet (3.048 meters), then the free bending force does not need to be greater than 50 tons. However, f yu are engaged in alarge number of bottomed die forming, perhaps a 160-ton machine toolshould be considered. Assuming that the thickest material is 1/4 inch, a 10-ot re bending requires 0 tos, and a botomed die bending (corected bendg) requre atleast o00tos. If mos prtsare 5feet or shorter, the tonnage is almost halved, which greatly reduces the cost of purchase. The length of the part is very important for determining the specifications of the new machine.

Modern and sophisticated materials are used in automotive engineering not only for the outer skin and structure of the actual car bodies but are also used in vehicle components such as the chassis, drive train, seats or trim parts. Auminum and steel are used for many components in the form of strips, sheets or plates, which are processed and formed in various manufacuring processes from semi-finished products to finished components. Even during these process steps, special demands are placed on the components. Due to the automated handing, good flatness and theloest possible degree of cut are very important for a machining procss itout comliations. Ifhese qualit criteria o not correspond to the defined specifications, there is no process reliability. Discover even more information on pressmachine-world.com.

The transformer is made according to the principle of electromagnetic induction Two windings, a primary winding and a secondary winding, are wound around the closed iron core column When AC power supply voltage is applied to the primary winding There is alternating current in the original Rao group, and the magnetic potential is established. Under the action of the magnetic potential, the alternating main flux is generated in the iron core. The main flux passes through the iron core at the same time, AC link the primary and secondary windings are closed, and the induced electromotive force is generated in the primary and secondary windings respectively due to the action of electromagnetic induction.

We know that the actual transformer always works in AC state, and the power loss is not only on the resistance of the coil, but also in the iron core magnetized by alternating current. Usually, the power loss in the iron core is called “iron loss”. The iron loss is caused by two reasons, one is “hysteresis loss” and the other is “eddy current loss”. Nanocrystalline magnetic core is a small part with magnetic conductivity. There are nanocrystalline particles with small particles in the center of nanocrystalline magnetic core. The working principle of nanocrystalline magnetic core is to absorb the common mode current in the cable through the principle of induction heating and convert it into heat to dissipate. rolled silicon steel sheet is selected. It is cut into long pieces according to the size of the required iron core, and then overlapped into “day” shape or “mouth” shape. In principle, in order to reduce eddy current, the thinner the silicon steel sheet, the narrower the spliced strip, and the better the effect. This not only reduces the eddy current loss and temperature rise, but also saves the material of silicon steel sheet. But in fact, when making silicon steel sheet iron core. Not only from the above favorable factors, because making the iron core in that way will greatly increase the working hours and reduce the effective section of the iron core. Therefore, when making transformer iron core with silicon steel sheet, we should start from the specific situation, weigh the advantages and disadvantages and choose the best size.

Amorphous Core is preferred choice for transformers required low losses at high frequency. We have amorphous c-cores,amorphous ribbon cores,amorphous cut cores,amorphous core transformers . Please find out more about crgo core material. There are 50% and 80% nickel iron materials available, in which we manufactures Mumetal Toroidal core and Mumetal C-core, for the applications in high quality Current Transformers and power supplies industries. Discover extra details at https://www.transmart.net/.

It is worth noting that Japan is vigorously developing FEMB amorphous alloy and nanocrystalline alloy. Its BS can reach 1.7 ~ 1.8T, and the loss is less than 50% of the existing FeSiB Amorphous Alloy. If it is used in power frequency electronic transformer, the working magnetic flux density can reach more than 1.5T, while the loss is only 10% ~ 15% of silicon steel power frequency transformer, it will be a more powerful competitor of silicon steel power frequency transformer. Japan is expected to successfully trial produce FEMB amorphous alloy power frequency transformer and put it into production in 2005.

After surface insulation treatment, the magnetic core is evenly mixed with the binder, pressed and annealed. There are basically three ways to obtain nanocrystalline powder: amorphous strip crushing after annealing and crystallization, mechanical alloying and molten alloy atomization. At present, mechanical alloying is still in the laboratory research stage. A few companies produce amorphous strip crystallization in small quantities in China, but it is unable to expand the market due to cost reasons. Compared with other methods, molten alloy atomization method has high efficiency and low cost. Its disadvantage is that the amorphous content of the powder is low and the loss is high.
