For the toilet paper machine to work properly, should develop equipment maintenance safe operation of the system in order to ensure long-term safe operation of the tissue machine, at the same time have the necessary repair tools and grease and the corresponding accessories. When tissue machine roller devices than 500 hours or so to replace the roller of each rolling bearing rollers kit must be cleaned, damaged parts should be replaced, fuel pumps and hand tools available grease gun. Tissue machine use in the process, should be fixed personnel responsible for the custody, the operator must have a certain level of technology. Toilet paper machine before installing the operator must carry out the necessary technical training to enable it to understand the principles of tissue machine performance, familiar rules.
Fruit and vegetable washing machine, vegetable washing machine is at work, the power supply to the ozone generator, ozone generator to produce ozone, ozone is pumped through the tube to the ozone washing vegetables machine tub, the washing machine tub in contact with water, dissolved in water to form ozone, ozone water has a strong sterilization, disinfection, pesticide degradation effect. Mainly used for cleaning vegetables and fruits. Heavy use of pesticides in today, all kinds of chemical preservation and preservatives, growth hormones various times, each family before this is completely in a state of non-resistance, can only passively accept every day in a by pesticides toxic chemicals in the process, such as various cancers and cardiovascular diseases are associated with long-term excessive intake of pesticides and various chemicals related, now has fruit and vegetable washing machine, you can make each of her family have had a advanced means of protection, in this life you can eat a lot of pesticides and a variety of chemicals, many diseases can be less too, people only live a healthy life is priceless.

Storage tank are containers that hold liquids, compressed gases (gas tank) or mediums used for the short- or long-term storage of heat or cold. The term can be used for reservoirs (artificial lakes and ponds), and for manufactured containers. The usage of the word tank for reservoirs is uncommon in American English but is moderately common in British English. In other countries, the term tends to refer only to artificial containers.
In the USA, storage tank operate under no (or very little) pressure, distinguishing them from pressure vessels. Storage tank are often cylindrical in shape, perpendicular to the ground with flat bottoms, and a fixed or floating roof. There are usually many environmental regulations applied to the design and operation of storage tank, often depending on the nature of the fluid contained within. Above ground storage tank (AST) differ from underground (UST)steel tank in the kinds of regulations that are applied.
Reservoirs can be covered, in which case they may be called covered or underground storage tank or reservoirs. Covered water tanks are common in urban areas.
Storage tank are available in many shapes: vertical and horizontal cylindrical; open top and closed top; flat bottom, cone bottom, slope bottom and dish bottom. Large tanks tend to be vertical cylindrical, or to have rounded corners transition from vertical side wall to bottom profile, to easier withstand hydraulic hydrostatically induced pressure of contained liquid. Most container tanks for handling liquids during transportation are designed to handle varying degrees of pressure.
A large storage tank is sometimes mounted on a lorry (truck) or on an articulated lorry trailer, which is then called a tanker.
Currently used in nitrogen, oxygen areas more carbon molecular sieve and zeolite molecular sieves. Separation of molecular sieve oxygen and nitrogen is mainly based on two gas diffusion rate of different molecular sieve surface, activated carbon and carbon molecular sieve is a molecular sieve certain characteristics of both the carbon-based adsorbent. Microporous carbon molecular sieve composition having a small pore size distribution in between 0.3nm ~ 1nm. Smaller diameter gas (oxygen) the proliferation of faster, more solid phase into the zeolite, so that the gas phase composition can be enriched nitrogen. After some time, the molecular sieve adsorption of oxygen balance, according to the carbon molecular sieve at different pressures for the absorption amount of gas different characteristics, reducing the pressure of the carbon molecular sieve adsorption of releasing oxygen, a process called regeneration. PSA typically use two towers in parallel, alternating pressure adsorption and decompression regeneration, so as to obtain a continuous stream of nitrogen.Similarly, the flow of oxygen and vice versa!
Oil and Gas Industry Special Nitrogen Making Machine
Areas of Application:
1. The well detection, oil, natural gas field exploitation, to improve oil and gas production;Oil and gas well completion and maintenance, to ensure safety.
2. Liquefied natural gas (LNG) production and transportation, liquefied gas cans protection.
3. Oil depot, pipeline maintenance purging, loading and unloading of oil and gas explosion protection.
4. All kinds of gas drive device and instrument panel of nitrogen protection.
PSA Nitrogen Generator Features:
1.Large amount of gas, high pressure.
2. Some places on carbon dioxide content, water content is very low.
3. Need explosion-proof, mobile, electricity or diesel.
Process characteristics PSA Oxygen Generator
1, the energy consumption is relatively low. The greater the oxygen production, energy consumption is also reduced.
2, low maintenance costs, and moving equipment Roots blower Roots vacuum pump, its working principle are positive displacement, oil-free, easy to maintain.
3, the high degree of automation equipment package, moving equipment and oxygen are synchronous control, simply press the start button, the entire device can operate normally.
4, suitable for medium and large-scale production.
With the rapid development of mobile communication networks, network coverage is growing, but because of a variety of building, developing road traffic, so that indoor wireless communications there are still some weak links can not meet the needs of customers, mainly the following problems,
1. blind spot: the signal after the loss is less than the phone receiver sensitivity, resulting in poor cell phone.
2. Weak: The main signal is lower than after the loss of the phone receiver sensitivity, resulting in poor cell phone.
3. conflict zones: mainly high-rise building area wireless signals from a plurality of cells, and more for the floor, wall instability reflected signal, resulting in frequent switching (ie ping-pong effect), seriously affecting the normal communication handset.
4. Busy area: mainly large traffic areas, station capacity is difficult to meet the communication needs of the user can not access the mobile network for communication.
For the above problem, by an increase in the base station or stations placed directly strengthen coverage can be solved, but the project is more complex and consumes a huge cost. How to improve the coverage in order to achieve seamless indoor network coverage, improve call quality, but also to maximize the reduction of costs is an important issue for network optimization.Signal amplifier and thus ushered in the era of the shield!
Features of cell phone jammer
1. Only shields mobile phone signals do not affect the normal operation of other electronic devices
2. Only shields mobile phone signals inside the examination room, examination room outside of the phone is not interference, but does not interfere with the base station
3. Only shielded transmission base station downlink frequency without affecting the uplink frequency
4. Green environmental protection, electromagnetic field strength is far below the national standard, without any effect on the human body
5. Operation is simple and correct installation of the antenna, connect the power to run automatically
cell phone repeater is this:
cell phone repeater is buffered into the secondary amplifier stage of the programmable gain amplifier PGA, by filtering the signal after amplification with the most flat frequency response characteristics of the filter is 8-order low-pass filter, which can be programmed setting the cutoff frequency from 10Hz to 100KHz, secondary filter second-order active low-pass filter to eliminate interference digital, low-pass filtering plus optional secondary band-pass filter, whose lower cut-off frequency of the use of pull switch settings , low-pass and band-pass filter can be programmed to access or skip.
