The sort and maintenance of racing radiators

Auto radiators can be divided into water-cooling and air-cooling. Air-cooled radiators achieve the heat dissipation effect depending on air circulation. So its cylinders are designed as dense sheet structure to increase heat radiating area, and meet the radiating demand. Compared with water-cooling auto radiators, air-cooling radiators have advantages of light weight and easy maintenance. Water-cooling radiators work by cooling the coolant of high temperature, and the water pump makes coolant circulating around the complete radiating system.

When the vehicle runs, dust, leaf and rubbish are easily to be attached to the surface of radiators and block the radiator vanes, which may influence the performance of radiators. In this case, we need to clean it with brush, and blow the dust away with high pressure pump. Auto radiators are inner components of heat conduction and heat transfer, and it plays an important role in vehicle performance. Auto radiators are mostly made of aluminum and copper. In materials, metal is not corrosion-resistant, so bot aluminum racing radiators and copper radiators should be protected from corrosive solution. For auto radiators, blocking is very common. To avoid this situation, we need to inject soft water inside, and then inject hard water inside radiators, to avoid incrustation scale. When it gets cold in winter, radiators are liable to frost damage, so it is need to be injected with anti freezing solution to prevent water from freezing. In daily use, check the water level at any time. When you add water to the auto radiators, keep yourself far away from radiator filter as much as possible, to avoid to be hurt by the high temperature oil.

The development of solar street lights

As the nation's continual readjustment of energy structure in recent years, our demand for energy continues to rise. As a classical renewable energy, solar enery receives more and more attentions for the characteristics of environmental protection, rare pollution and extensive applications. Road lighting projects, which is represented by solar street lamps, have been treated as "political carrer" and "environmental projects" by more and more local governments, which leads to a flurry of road-building. But the rapid expansion of solar energy has its disadvantages surely, as followed are the main problems of solar garden lights:
1. Poor quality of solar panels. It is certainly that we should not be too worried about the quality of solar panles produced by regular manufacturers, because they have had a relatively sound testing standard and testing equipments. But what should be mentioned here is that the power measurement of solar panles needs to use exclusive equipment, and government has no relevant detection measures about this critical technical specification, which makes the solar street lamps can't work normally for power shortage.

2. Light source. Among all the electric devices, light source costs the lowest, but has the highest failure rate. Among all solar lighting fixtures, flood lamps, energy saving lights, high voltage sodium lamps, and halogen light bulbs are relatively common cases. To avoid the power loss caused by inversion, most of them use DC input, and both the design and production are professional. At present, there are many manufacturers producing all kinds of light sources in the market, but only a few of them can ensure high quality. Some suppliers attract customers with low prices, but their products may fail to work in a short time, which caused big negative impact on the application of solar street lamps.
3. Control unit. Some controllers are not perfect enough to control and protect the charge and discharge process of storage battery, which may cause over-discharge and over-charge. Controllers should adopts SOC control method, which can ensure the SOC level below set value and protect the storage battery from over-discharging.
LED downlights have the characteristics of safe and energy conservation, environmental protection, easy installation, automatic control and easy maintenance. Currently it has been very popular in European countries, and it is still in the beginning stage in China.

How to understand split case pumps correctly?

Split case pump can also be called single stage double suction split case pump, and its main feature is the large flow rate of transmission medium. The impeller is installed inside the pump case, and fixed to pump spindle. Pump spindle is drived diretly by electrical machine. There is a liquid suction tube at the center of the pump case. Liquid enters into the pump through bottom valve and suction tube, and the liquid exhaust port is connected with the discharge pipe. When the pump's rotate speed is constant, the pressure head and flow rate are about the diameter of impeller.

Split case pump is a general mechanical equipment that can be widely used in oil, chemical industry, electric power, mine, shipbuilding, light industry, agriculture, civil use and national defense department etc, so it plays an important role in national economy. To select the split case pumps reasonably, we have to consider those economic indicators including the operation costs of pump set and pump station, and makes it conforms to economic, safe and pratice principles. To be specific, there are four aspects that you should take into consideration.
1. It must meet the requirements of flow rate and lift. We must keep the split case pump running efficiently, so that it can not only save power but also makes the machine parts more durable.
2. The split case pump should not only meet the requirements of small volume, light weight and cheap cost, but also have good characteristic and high efficiency.
3. It needs to have good resistant to capitation erosion, long span life and stable operation.
4. The pump project should feature lower cost and less investment.

The unique point is that the machine itself features with fully automatic sterile technique and HY special disinfectants, it can not only clean the blots that can be viewed with naked eyes, but also kill various kinds of harmful bacteria and viruses, and the effective rate can reach as much as 99%.
3. Large capacity and microminiaturization. Large capacity washing machines can meet consumers' requirements of washing big items. At the same time, micro washing machines become more and more popular at present. For this group, Haier launched micro washing machines including 1.5kg, 2.5kg and so on, which can meet the requirements of washing a relatively less amount of clothes.
4. Modularization. Royalstar launched child-mother separated washing machines, with a 5.5kg large tub and a 2.5kg small tub, which reduces the machine space largely. It has artificial intelligence fuzzy control function to realize the requirement of washing an inordinate amount of clobber at the same time, and washing less amount of clothes immediately. It is predicted that this design will be well received by consumers in the near future.

5. Heating water function. The eariler roller washing machines have heating function, becuase warm water can not only kill virus, but also imprive the effect of abstergent. In 2003, this function was copied to twin tub washing machines too.
6. Electric direct drive. Qishuai launched five high-tech models, and two models are about the combination of DD direct drive technique and digital control technique, which realizes mute, energy conservation and precise laundry. On the other hand, the direct drive washing machines are high intelligent products, and they can provide fine control platform for intelligent control and network control of washing machines industry.

The features of SEN GUANG solid tires

Excellent safety performance

The main material of solid tires is rubber, which maximum its anti-explosion, also eliminates the hidden trouble that the tires of industrial trucks might be punctured in hostile working environment. Solid forklift tires don't need to inflate, so it also avoids heavy work of changing tires frequently, which increases the utilization rate and work efficiency of vehicles. For those low-speed vehicles that run efficiently, skid steer solid tires can take the place of pneumatic tires totally.

Reasonable structure design

SEN GUANG solid tires use the advanced three-section structure design. Three sizing materials guarantee the whole performance of tires respectively. High rigidity and high strength tread slab base and steel ring base not only guarantee the plumpness of tire, but also the sturdiness of rim, which definitely solve the sliding problem of traditional pneumatic tyre. The high elasticity mid-sizing can avoid vibration effectively when the vehicle is running. Thickened thread makes the solid rubber tire have the wear-resisting performance, and help improve 30% cutting life. Besides, the special inner structure design makes sure that tires can work in close conjunction with rim, which improves the stability of solid tires.

Advanced technology and design

SEN GUANG, with more than 30 years of production history and experience, has the most advanced technology in the industry. It improves the usability of solid industrial tires to the hilt in rubber formulation design. In particular, it uses the imported sizing of high rigidity and low heat as the material of tread slab base, so that tires can run with a minimum heat and temperature. It improves the heat-resistant quality of solid tires, and solves the bursting, swelling and sliding problems of pneumatic forklift tires caused by high temperature.

By tested by State Construction Machinery Quality Supervision and Testing Center, SEN GUANG Chinese tire manufacturers have equivalent resistance coefficient to pneumatic tyre, so customers don't need to worry about the gas-guzzling problem of solid tires. Besides, SEN GUANG also introduced the newly designed non marking tires featuring high performance, which realized no skid marks and environmental superiority, and it is especially suitable for industries which have strict requirements on environment, such as foods, textiles, electrons, pharmaceuticals, aviation, etc.

Solve problems that pneumatic tyre is easy to crack and break

Because SEN GUANG uses imported viscose to make tread slab base, and viscose have the advantages of good rigidity, high hardness, hard to distortion, low dilatation coefficient and low themogenesis, so it eliminates the slip phenomenon caused by heating up.
The reason why traditional pneumatic forklift tires are easy to crack and break is not only because of abrasion during use process, but also caused by rubber aging, mostly thermal ageing and light aging. And the use of viscose can reduce production of heat when tire is running, so it solves crack and break phenomenon at its most fundamental.

The potential market of solid tires

To industrial trucks, tires play a pivotal role. The selection of tires depends on the model, scale, weight of vehicles, as well as the ground roughness, temperature and transportation condition. Solid industrial tire is a special tire, which is mainly used in hijacking vehicles, armor cash carrier, anti-terrorism car, engineering vehicle and other special vehicles. Currently, the application of solid tires is not widespread, while its developing prospect is very good, which is a good condition for those solid tires manufacturers. In recent years, some famous tires businesses also turn their sights to the market of solid tires. Take Michelin as an example, it has already produced solid tires a few years ago, but it didn't run a mass production. Instead, Michelin just brought it to those high-end models, such as Rolls-Royce. I think it is probably because of the high cost of production.

Not only those traditional businesses, but also some American defense industry enterprises also set their foot on solid tires. By report, they have invested $27 million in this field. The most prominent characteristic of solid tires is good wear and puncture resistance, and anti-explosion. It is mainly used in military vehicles. For example, the US army did use such tires in the Iraq War.
There are also some Chinese tire manufacturers that are trying to produce solid tires, but mostly for engineering vehicles. Personally speaking, businesses should pay more attention on anticipating customer demands, so that solid tires can be brought to the market successfully.
