Tungsten Carbide High Head Cutter Pump

New CR series 3” and 4” tungsten carbide high head cutter pump produce heads of up to 70 metres.  Designed for cutting fibrous material in industrial or effluent/sewage applications, the new series was developed for applications where pump out either over longer distances or higher elevations is required.
“The new tungsten carbide high head cutter pump range is expected to be of real interest in sewage, effluent and industrial waste applications where more head is required than conventional equipment”, said Australian Pump Industries’ manager, Neil Bennett.  “The combination of the ability to chop material and pump to a high head is a new development,” he said.
The new three-phase CR series start from 2.2kW units that offer flows of up to 600 litres per minute with heads to 20 metres.  At the other end of the scale, the big 22kW 4” version delivers maximum flow of 1700 litres per minute with a head of 70 metres.
All submersible pumps are backed with a 3 year warranty. This is possible because they incorporate features that make them extremely robust and they are designed for an extended working life in severe conditions.

CR series incorporate a cutter mechanism that consists of a Tungsten carbide tip channel impeller and a saw-tooth suction cover hardened surface.  The cutter mechanism cuts fibrous material into small pieces permitting clog free pumping.
Like all sewage and wastewater pumps, the new CR series come with a unique anti-wicking cable entry.  This mechanism protects the motor by sealing the stripped back cable conductors with a moulded rubber or epoxy “potting” which has been loaded between each strand of the conductor.  This unique feature prevents wicking along the strands of the conductor itself and protects the motor.

The motors are dry type squirrel-cage induction design, housed in a water-tight casing.  They conform to insulation classes E or F.  In each of these insulation classes all standard pumps can be used in ambient temperatures of up to 40 degrees Celsius.
The CR series mechanical seal is a double silicone carbon style located inside an oil chamber.  The oil chamber, located beneath the pump chamber and the motor, prevents the ingress of water to the motor.  Tsurumi’s fully oil immersed mechanical seals eliminate spring failure caused by corrosion, abrasion or fouling.

The seal chamber is also fitted with a patented “oil lifter”.  This is a lubricating device for the mechanical seal.  It utilises the centrifugal force if the shaft seal by forcibly supplying lubricating oil to the mechanical seals.  This simple device protects both seals, lubricating and cooling but retaining stable shaft seal effect to extend life.
Pumps up to 7.5Kw have an auto cut out resetting CTP (Circle Thermal Protector).  This is integrated into the motor housing.  The CTP directly cuts the motor circuit if excessive heat builds up or an overcurrent caused by electrical or mechanical failure occurs.
Sliding discharge connectors are also available for the cutter pump range and are popular for permanent installations.  Pumps can be easily removed for maintenance without the need to drain the wastewater pond. The C series are available in a wide range of options from 50 through to 100mm discharge bores and with power ratings of between 0.75Kw to 15Kw.

Illegal Sewage Discharging Fined 500,000 RMB, Wo3 Photocatalyst Degrades Papermaking Wastewater

papermaking wastewaterRecently, a paper company in Tianjin due to illegal discharge of industrial waste water, and cause serious pollution to the surrounding environment, was fined of 500,000 RMB. It is reported that this paper-making company is mainly engaged in papermaking from waste paper, and has been handled the environmental protection acceptance procedures; according to the requirements, its generated wastewater should be recycled after treated with the treatment facility, but can not efflux. However, the data on-site inspection showed that the total suspended solids discharge ports exceeded by 18 times, chemical oxygen demand COD exceeded by 24.5 times; the suspended solids of sewage pit outside the plant exceeded by 163 times, chemical oxygen demand exceeded by 123 times, now you can see how serious the pollution is.
 
Papermaking industry occupies an important position in the national economy, which produces a large number of waste water, which is difficult to deal with, and causing serious pollution. Currently, the methods to treat the black liquor at home and abroad are: alkali recovery, coagulation, acid precipitation, biochemical and liquid membrane separation method, and so on. One of the most successful is the alkali recovery method, but because of the large investment, high cost, low alkali recovery and other disadvantages, it is difficult to promote.
 
Tungsten trioxide (WO3) having catalytic properties, not only can be used as the main catalyst to bring out effective utility; but also can be used as the additives to assist an catalyst for improving its activity. WO3 as a semiconductor photocatalyst, with its band gap of 2.4eV ~ 2.8eV, it can response to visible light, when irradiated under the sufficient light energy, electrons will carry out a transition to form a redox system by producing photo-generated electrons and holes, thus to play catalytic oxidation. Studies have shown that composite WO3/α-Fe2O3/W photocatalyst has good results in the depth treatment of papermaking wastewater. Under the optimum conditions, the COD and color removal rate of papermaking wastewater can even reach to 68.3% and 71.2%, respectively, the waste level of water handled deeply with WO3photocatalyst reached the national emission standards. Although, currently the most widely used photocatalyst is based on titanium dioxide, however, with the depth researching of photocatalyst, tungsten trioxide because of its superior performance and non-toxicity, is expected to become the main force of the photocatalyst.

 

Cities Introduce Policies to Reduce Logistics Costs, Accelerating Transactions of Tungsten Products (Tungsten Heater)

Recently, according to the data released by National Development and Reform Commission, it is said that logistics costs was 10.8 trillion RMB in last year, accounting for 16.0% of GDP. Therefore, many cities have been introduced many policies for enterprises to reduce logistics costs, it is possible to significantly reduce the passage money of highway.

"2015 National Logistics Operational Aspect Briefing" shows that the total cost of social logistics is 10.8 trillion RMB in last year, an increase of 2.8% over the previous year, accounting for 16.0% of GDP. Vice Director of China Federation of Logistics and Purchasing Zhouzhi said that the current charge of highway accounts for 30% -40% of the main transport business costs. The member of the National Committee of CPPCC and the vice-chairman of All-China Federation of Industry and Commerce Xu Guanju said that if the logistics cost increases, it will become a stumbling block to the development of domestic manufacturing enterprises.

By reducing the passage money of highway would further reduce logistics costs, which will directly affect the development of tungsten enterprises. Tungsten heater is one of the main tungsten products, and highway transport is the most important way to transport goods. This year China's provinces began to reduce logistics costs and make the appropriate measures. Hubei province has been reduced the province's highway charge about 10% from June 1 this year, and Shanxi province introduced preferential policies by a wide margin for the trucks of highway from May 20.

These policies not only help reduce product transportation costs, but also allow truck drivers benefit from it. Many truck drivers said that reducing the passage cost of highway, they are able to save some of that money. While reducing the cost is conducive to the development of manufacturing enterprises, but the requirement of repair and maintenance to the highway would be stricter, and the increased of vehicular traffic is bound to increase the burden on the road.

Netherlands Haze Purification Tower to China, WO3 Denitration Catalyst Boosts Air Purification

On June 28, Beijing started the public welfare activity of "Reduce haze in Action", and released the five sub-activities of the whole people common revise "Three Character Classic of Green Life" and so on. However, the most striking is that the Netherlands haze purification tower which once set off red-hot in the circle of friends is expected to be introduced to China in July, and begin to handle haze in Beijing at the beginning of September. It is reported that this haze purification tower which is up to 6.5 meters is inspired by the Beijing haze, it can absorb 75 to 80% or more of the haze in the air; and each 30,000 cubic meters of air purification only needs to consume 30 watt of electricity with safety and energy saving. Interestingly, the inventor was whimsy, he collects the gray haze and then makes it a ring by compressed the carbon into a black gem, which is really turning waste into treasure!
 
Of this invention, Yahoo Makers reported as follow: What’s 23 feet tall, eats smog for breakfast, and makes jewelry for fun?

Beijing haze is the most serious area of China, since the haze was put on the issue, it has been cause for many concern. In June, the Ministry of Environmental Protection released the air quality during April and May of Beijing, Tianjin, the Yangtze River Delta, Pearl River Delta region and the overall country's; data shows, PM2.5 concentration decreased year on year in Beijing, which is a good performance.
 
Haze governance is an important part of air purification, nitrogen oxides and sulfur oxides are a major source of air pollution. Since China is a country of coal energy sources, coal burning flue gas desulfurization and denitration projects have become the key of environmental protection. At present, the most commonly used of denitrification project is SCR technology, and it takes WO3 denitration catalyst as the core part, which accounts for about 30% of the denitration system investments. The activity of WO3 denitration catalyst played a direct impact on SCR denitration efficiency, and WO3 is mainly playing the supporting role of anti vulcanization, anti-toxic, anti-sintering of carrier ect. in the denitration catalyst, existing as a catalyst promoter. With the ongoing in-depth and transformation of denitration projects, as well as the improving of the denitration catalyst, WO3 will play an increasingly high effectiveness in SCR systems.

 

Brexit from Europe, Cross-Border Transactions of Tungsten Heater or be "Hit"

According to the British Broadcasting Corporation (BBC) reported that on the local time on June 24, the referendum vote for Britain to leave the Europe has been counted, the results show that 52% of Britain citizen support to exit from Europe, which means that the UK will be out of the EU. Influenced by the referendum, the pound plummeted substantially, the euro and the dollar also fell more than three percent, while the Swiss franc, the Japanese yen is skyrocketed, this brexit directly burns the global currency market, in order to stabilize their economic, and there many countries has been intervene the national economic.

European a major place for cross-border imports as electricity suppliers, and it is an important export market for cross-border electricity supplier. But now the state of the economy of the whole Europe is in shock period, the pound and the euro will likely to depreciate for a long period, which benefits domestic tungsten enterprises for importing related equipment. In this way, domestic tungsten manufacturers can improve the quality and quantity of tungsten products (tungsten heater). But on the other hand, export becomes an issue. Business profits will decrease. The industry said that at present the most cross-border electricity supplier for China and European logistics companies (excluding postal operators) in China have a layout in the UK, a large proportion of shipments should be pass the UK into the EU (dedicated line, overseas warehouses, etc.) . Therefore, for those service providers, they will be more or less affected.

In fact, the United Kingdom and Europe are not ready to the follow-up work for brexit. Britain has little effect to core business of SprintPack in a short time, because the British and European countries need to establish the appropriate bilateral agreements. The global economy will be in a long grace period, countries should make the appropriate measures to stabilize their economies.
