On July 24 at 2:22 pm (Beijing Time), Wentian lab module was carried by a Long March 5B rocket that blasted off, marking another important step in the construction of China‘s space station.

The Wentian module is the second large module of the Chinese space station after the Tianhe core module, with an axial length of 17.9 meters and a weight of 23 tons. It is the largest single module in the construction of China‘s space station. Wentian space lab will be the main workplace for astronauts during orbit with the main function of carrying out scientific experiments. In addition, Wentian space lab also needs to back up the functions of the Tianhe core module. When Tianhe core module fails, it can be switched to the Wentian module. Wentian looks like a “Hercules” with wings and its shape is very different from that of the Tianhes because it has a pair of huge solar panels at the tail to ensure the power supply of the space station.

Luoyang Bearing Research Institute Co., Ltd.(ZYS), as the main supporting high-quality manufacturing enterprise in the aerospace field, undertakes the task of developing and producing bearing components for the sun-centripetal mechanism of the solar windsurfing panel of the Wentian module. The solar panel is adjusted to the heliocentric mechanism to maintain the best angle with the sun’s rays, and the direction to the sun is always maintained, so as to avoid other modules blocking the sunlight during the flight, and to ensure the continuous power supply of the space station.

The bearing assembly has high design precision, difficult processing technology, and requires more longer on-orbit life, especially posing new challenges to lubrication technology. Through continuous technical research, repeated process analysis, multiple rounds of processing trial production, and sufficient performance tests, ZYS has finally successfully developed products that fully meet the requirements, and the lubrication technology has achieved independent and independent innovation.

Over the years, ZYS has been developing special bearings, bearing components and momentum wheel products for China‘s aerospace engineering, and has successively completed the “Dongfanghong” series of satellites, the “Shenzhou” series of manned spacecraft, the “Chang’e” Lunar exploration project, and BeiDou Navigation satellite series satellites, etc. Success is hard-won, and struggle is accompanied by hardships. In the future, ZYS will keep in mind its mission, continue to climb new heights in aerospace science and technology, and make new contributions to building a strong aerospace country and realizing the great rejuvenation of the Chinese nation.

The week-long “China Bearing & Power Transmission Online Expo 2021” (April 12-17, 2021) had provided wonderful business chances for global distributors and suppliers in the past 2 days, and the Expo will proceed further with the upcoming events.

Today we look at Multiport Valves, defining the valve functions, or valve settings to know which to use, and when and why to use them.

Multiport valves are called multi-ports because inside the valve, there are multiple ports that allow the water to move in multiple directions. Pool water always enters the valve thru the “PUMP” port, but depending on the handle position, the water enters the filter tank through the top bulkhead or bottom bulkhead. Also dependent on the handle position, water exiting the valve either uses the “RETURN” port or the “WASTE” port.

1. The FILTER Position:

This is the normal setting for your filter valve. Water is pulled from the pool by your pool pump and pushed into the “PUMP” port of the multiport valve where it enters the filter tank. On sand filters, water enters at the top of the tank, and for DE filters, water enters at the bottom of the tank. After passing through the filter media, the water exits the tank again into the multiport valve, leaving through the “RETURN” port, and back to your pool.

Another use of the “Filter” setting is while vacuuming the pool of debris large enough for the filter or pump basket to remove. You will want to use the next setting if vacuuming dead algae, silty mud or flocculent treatments, or other such fine filter clogging material.

2. The WASTE Position:

The most common scenario in which you would use a multiport valve “Waste” setting is when lowering pool water levels. Waste diverts the water pumped in from your pool from the filter and sends it directly out of the backwash hose, without even entering the filter tank. It’s one of two ‘Bypass’ settings on a multiport valve.

The other common instance in which you would use the “Waste” setting is when you are vacuuming debris that is too fine for the filter media to capture. Have you ever vacuumed your pool on the “Filter” setting only to notice a few hours later that a fine, almost sand-like sediment has collected at the bottom of your pool? This is not uncommon for sand filters, which can have trouble trapping very small particles.

3. The CLOSED Position:

Simple enough, “Closed” is a position that won’t let water enter the valve, and is the most rarely used position of all. The pool pump should never be turned on when the MPV (pool guy shorthand) is in the ‘Closed” position, something could blow out!

The “Closed” position is sometimes used when blowing out suction lines during winterization, to direct air flow back to the pool. It could also be used to stop water flow into the tank for filters that are below water level. In both cases however, there are usually other valves that can be used to accomplish the same thing.

 4. The BACKWASH Position:

The “Backwash” setting reverses the flow of water in and out of the filter tank. During normal filtration, on the “Filter” setting, water moves through the filter in one direction – top to bottom for sand filters, and bottom to top for DE filters. When the MPV handle is moved 180° to the “Backwash” position, water flow is reversed as it enters and exits the filter tank. And, when the water leaves the filter tank and re-enters the MPV, it is directed out the “WASTE” port, instead of the “RETURN” port.

Backwash a filter when the pressure gauge reads 7-9 psi above the clean operating pressure. Run the pump for 2-4 minutes, discharging through a backwash hose until the water in the sight glass, or at the end of the hose, is no longer dirty or cloudy.

5. The RECIRCULATE Position:

The “Recirculate” setting is another bypass setting like “Waste”, where the water does not enter the filter tank at all. After the water enters the MPV it makes a quick U-turn, and exits the valve out of the “RETURN” port, returning to the pool unfiltered.

The best use of the “Recirculate” position is when your pool filter is broken, leaking or otherwise cannot be used. In many such cases, the “Recirculate” position will allow you to at least circulate and chlorinate the water, to prevent stagnation and algae, until the filter can be repaired or replaced. This position may also be used when blowing out the lines, to avoid unnecessary high air pressure inside the filter tank. “Recirculate” is also used when adding Alum or other flocculents to improve water clarity.

6. The RINSE Position:

If you have ever vacuumed your pool spotlessly, and then after backwashing, sent a cloud of dirty water shooting into the pool, we have an app for that – the “Rinse” setting on a multiport valve. This position moves water through the filter tank in the normal direction (top to bottom for sand, bottom to top for DE), but when the water re-enters the MPV, it is directed out the WASTE port, not RETURN.

The “Rinse” position is used after backwashing a sand filter, to flush out or rinse the sand bed of remaining dust particles. 15-20 seconds is all that is needed to re-set and rinse a filter sand bed. DE filters with small holes in the grids or cracks in the manifold may also benefit from a rinse after backwashing, but outside of that, “Rinse” is not normally used after backwashing DE filters.

7. The WINTER Position:

The “Winter” or Winterize setting is used when it’s time to close your pool for the season. You will notice that this position is not actually a position at all, but is a location in-between two positions – there is no groove to lock the handle in place. What the winter position does is to ‘prop-up’ the valve diverter (aka rotor or footpad), raising it above the ‘multi-ports’ inside of the valve.

In this position, with the internal spring compressed, the diverter remains in a suspended position all winter, held 1/4″ above the valve body ports. This allows space for any water trapped inside the valve to expand into ice during winter, without cracking the valve body.

---

Multiport valves are available in top mount design with flange attachment for sand filters, and in a side mounted design with bulkhead unions, for sand and DE filters.

Multiports are full featured, but may require multiport valve repairs from time to time. We have a full selection of multiport valve parts, and filter valve rebuild kits, containing gaskets, o-rings and seals.

One more TIP: Be sure to always shut off the pump before turning the MPV handle. Changing positions while the pump is running can damage the valve, or cause something to blow out under pressure.

Many people think that writing is one of the things you either have the ability to do well, or you don’t – there is no middle ground. However in reality, most writers will tell you that it took them years to really figure it out. It’s just like anything else, if you want to get better; you have put in the time and really focus on how to improve your writing skills.

Here are some tips that will help if you’re interested in learning how to get better at writing.

How to Improve Your Writing Skills

Don’t Edit (In the Beginning)

One thing that is difficult for new writers to understand is that writing and editing are not the same thing. If you try to edit while you write, you will never get anything done. You will spend so much time on editing the details that you’ll lose your train of thought and maybe even your “flow” or inspiration.

A nice tip if you want to improve your writing is to turn your monitor off while you’re writing. That will allow you to completely focus on your thoughts and getting them down on paper.

Learn the Rules, But Break Them

There are many “rules” that must be followed when you’re writing. But if you are writing and feel strongly about something, don’t be afraid to break those rules. The originality you’re showing might be what makes your article, book, etc really great.

Learn to Accept Criticism

This is a hard one for many writers, but if you want to improve your writing, it’s important that you let other people look at your writing and give you feedback. It’s just as important to learn to accept that feedback. Everything is valuable, even when you don’t agree with it.

Use the Thesaurus

Everyone has words that they like to use, but it’s too easy to become too dependent on those words. Another great way to improve your writing is to use a thesaurus while you’re editing. An easy way to do this is to right click on a word (if you’re using Word) and check out the thesaurus options to see if there is a more descriptive word that works better.

Use Fewer Words

If you really want to become a better writer, try to reduce the number of words you’re using while you’re editing. Too often, writers get too “wordy”. Look at each sentence and determine if you can cut it in half and still get the same point across.

Shorten Your Sentences

Another great tip for writers is to reduce the size of your sentences. While the long, drawn out thought might technically be considered as a single sentence, that doesn’t mean it should be. People can listen to long sentences, and it works ok. However, when you’re reading a sentence that is too long, and has too many commas, it becomes too easy for the reader to get lost in the main purpose of the sentence because it goes on for far too long. (Like the sentence you just read!)

Do you really want to improve your writing? Then use shorter sentences.

Spelling and Punctuation Matter

Some people believe that if WHAT you write is compelling and interesting enough, it doesn’t matter HOW you write it, but that isn’t the way it works. If you don’t take the time to fix your grammar and do a spell check, it will cause a problem. The best case is that your errors will be distracting for the readers, but the worst case, is that you will lose credibility and they will even stop reading because of the errors.

The current Chinese manufacturing industry is different from the past. After more than 20 years, many consumers have never understood the true strength of China's bearings.

When it comes to bearings, the raw material bearing steel is definitely inseparable. In the past, domestically imported bearing steel from overseas to develop bearings, but now China is the bearing steel supplier for major international manufacturers such as Sweden's SKF, Germany's Schaeffler, and the United States' Timken.

Not only bearing steel, China has two other technologies that are already at the forefront of the world.

One of them is the bearing steel ball.  As is known to all, Japan Toonashima Group is an internationally recognized top manufacturer in the field of precision steel ball manufacturing.   

However, Chunzhongdao Group was previously exposed to purchase Chinese bearing steel ball products, and then disguised as a scandal of selling Japanese bearing steel ball products.    

To this, Chunzhongdao Group confessed, and explained : this is because of their bearing steel ball product output is insufficient, and China precision steel ball and meet customer requirements standards, safety has no effect.  So the Chinese steel ball disguised as Nissan sold to customers.    

It is worth mentioning that Shandong Dong ' a Steel Ball Group has also reached a strategic global partnership with German Scheffler and Swedish SKF.  Its products are exported to the UK, the US, Japan, Germany and other countries.    

In addition to Dong ' a steel ball group, Lixing, as a domestic precision bearing steel ball leading enterprises, has been successfully listed as early as 2015, is also a supplier of giants such as SKF.

The second technology is the bearing ring.  In the field of bearing ring manufacturing, Zhejiang Wuzhou New Spring is a worthy industry leader.    

The automobile bearings of Zhejiang Wuzhou New Spring are widely used in BMW, Ford, GM, Nissan and other internationally renowned automobile brands.  Its bearing rings are mainly supplied to Sweden SKF, Germany Scheffler, Japan NSK manufacturing giants.    

In addition, China ' s Dalian Ruigu Technology is also a supplier of these international giants.  However, Dalian Ruigu Science and Technology supplies bearing cages. In the global bearing subdivision industry, the company ranks first in the world and is the maker of industrial standards.    

From this point of view, China ' s bearing has successfully run from heel to lead, to achieve a qualitative leap, hope that more and more high-tech technology can be broken and mastered.
