制革转鼓供水技术参数问答

1、重要注意事项:

1)供水混合水主管必须大于实际口径。如:65的供水、必须配置80的主管;80的供水必须配置100的水管。

Notice the practical parameter of main tube for mix water must be larger, for example, The WATER 65 must be equipped with tube in diameter of 80; WATER 80 must be equipped with tube in diameter of 100.

2)每套供水必须配置3给手动阀,分别是进水2个、出水1个、便于故障时切断水源、进行维修。

Each set of water supply system must be equipped with 3 manual valve, 2 in 1out for maintaining in case of emergent failure.

3)进入转股的供水管、不能太短、也不能太长、合适的尺寸是:与转股孔不超出为宜。

The tube in the drum must not be too short or too long, the adaptable size is to be just equally fit for the hole.

4)回水的蝶阀应该装在接近水箱的位置。

The valve for returned water must be fix near the water tank.

2、供水有哪几种口径?一般比较常见的有506580 我们在海宁富邦还有100口径的

What’s the size of tube for water supply? In ordinary condition, the size is 50, 65, 80. There is size 100 in Fu Bang, Hai Ning as well.

3、供水口径是什么单位?

是以供水管道的内径,为毫米(MM)。

What’s the unit of water supply? It is determined by the inside diameter of watering tube. It’s measured by mm.

3、配置管道时如何换算?

水管常用尺寸对照DN154分管DN206分管)、DN251寸管)、DN3212管)、DN401寸半管)、DN502寸管)、DN652寸半管)、DN803寸管)、DN1004寸管)、DN1255寸管)、DN1506寸管)、DN2008寸管)、DN25010寸管)等。

How to choose adoptable tube? There are many sizes for your reference. DN15 (1/2 inch), DN20 (3/4 inch), DN25 (1 inch), DN32 (5/4 inches), DN40 (3/2 inch), DN502inches)、DN652.5 inches)、DN803inches)、DN1004inches)、DN1255inches)、DN1506inches)、DN2008inches)、DN25010inchesetc.

4、供水口径与转鼓的关系

要看转鼓的进水轴头口径、原则上、供水口径要要与转鼓进水的口径相等才行(大了就进不去)、也有的厂因为转鼓只有65、供水是80的、没办法、把80的口径再转换65进入转鼓、这样的后果是水温不稳定。

What’s the relationship between the unit of water supply and the drum?

.Technically, the diameter of tube for water in must be equal to the diameter of the drum. In some factories, the diameter of tube for water supply is 80, however, the unit diameter for drum is 65. So they convert the 80 tube to 65 consequently, the temperature of water is not steady.

5、在不同口径条件下、水泵的配置需要有变化吗?

口径不同,扬程,功率和流量也不同。

For different diameter of tube, should it be equipped with different water pump?

Of course, different size of tube be with different power, lift and quantity of flow.

6、一套供水、他总的需要多少功率?

2个水泵的功率、另加100W,大概在:6kw15kw

What’s the needed power for one set of water supply system?

Its power is from 6kw-15kw. It’s for two water pump plus 100w.

7、一套供水的冷水池需要多大面积?每小时的产水量需要多少?

水池和进水量从正比,进水大于出水的时候,水池就可以缩小,反之要加大、此外、还要考虑是一台还是数台供水、总之、在全部供水工作时、水箱要能满足供应。参考数值:

50:每小时加水25

65:每小时加水40

80:每小时加水60

100:每小时加水110

What’s the area of cold water tank in a set of water supply system? What’s the productivity of cold water in one hour?

The size of tank is in direct proportional to the quantity of water supply. When the quantity of water in is larger than that of the returned water, the tank can be waned. In reverse, it should be expanded. Also, it should be considered that how many drums should be supplied with water. When all the drums are on working, the tank should be able to supply that much of water. Reference:

50: add 25tones of water per hour

65: add 40tones of water per hour

80: add 60tones of water per hour

100: add 110tones of water per hour

8、一套供水的冰水箱需要多大?

目前、各地客户一般冰水配置为20立方左右,

What’s the size of cold water tank for a set of water supply system?

Standardly, it’s about 20 cubic.

9、一套供水的热水箱需要多大面积?每小时的产水量需要多少?

这个和转鼓的用途有区别,如果做鞣制和染色的热水量大,毛皮和锓灰的热水量小。一般大概在20立方左右,进水在每小时30-40立方左右

根据福建的经验:65口径的、热水箱每小时3050立方;80口径的每小时5060立方水

What’s the size of hot water tank for a set of water supply system? What’s the yield productivity?

It varies because of the different usage of drums. If you use it for tanning and dyeing, the volume of the hot water should be big. If you use it for liming, the volume should be smaller. Ordinarily, it’s about 20cubic, 30-40cubic per hour.

According to our experience in Fu Jian, for size 65, the speed for hot water is 30-50cubic per hour. For size 80, the speed is 50-60.

10、冷水池距离供水的理想距离是多少?

越近越好

What’s the ideal distance between cold water tank and water supply system?

It is the closer, the better.

11、热水箱距离供水的理想距离是多少?

越近越好

What’s the ideal distance between hot water tank and the water supply system?

It is the closer, the better.

12、冷水池接入供水的距离远会有哪些问题、如何解决?

抽不出水和压力低,解决办法:把水泵装到水箱边上去

What’s the problem if the cold water tank is far from the water supply system? How to fix it?

The pressure is low so it’s not easy to pump the water.

Solution: Install the water pump near the water tank.

13、冷水池接入的管道应配置多大?是80就接入80? 还是要比80大些?

多大就接多大,最好保持出水管道和进水一致,或者只能大不能小、

What’s the size of tube for cold water tank? Is it 80 for 80? Should it be larger?

The size for the diameter of tube of cold water tank had better be equal to that to the water supply system. It can be larger but not smaller than the diameter of tube to the water supply system.

14、冷水池接入供水的管道要考虑哪些因素?

口径、距离和水量、

What should be considered when connect the cold water tank to water supply system?

The size, distance and the volume of water should be considered.

15、水塔与恒压供水那种好?

水塔

What is he better, water tower or constant pressure water supply system?

Water tower is better.

16、如果客户使用恒压供水会对供水产生哪些影响、如何消除?

恒压供水会在自动供水停机的瞬间会把压力增到很高(大的能超过1MP多)。消除这种问题的方法:当常温水恒压在0.25MP以上的时候,冷水泵停止工作、另在冷水泵的位置做个气动蝶阀(让气动蝶阀在供水工作时打开,供水停止时关闭)

What’s the side effect if you use constant pressure water supply system? How to relief?

For the constant pressure water supply system, the pressure rises sharply when the auto water supply machine stops working. (Over than 1Mpa)

To fix it, when the water is about 0.25Mpa, the cold water pump should stop working. Besides, install an air operated reed valve. (Turn on the valve if the water is in. Turn it off when the water stops.)

17、如果客户的水源距离供水很远如何解决?

做无塔恒压供水或做水箱二次供水(如果在200米内还可以做水泵房,加个增压水泵的方法,具体可以参考平舆永盛皮革)

What if the source of water is far from the water supply system?

Constant pressure water supply without tower or secondary water tank is the solution. Within 200m, you can put a water pump station)

18、供水发生断水会出现什么情况?

1)如果发生断水的时候,供水基站上的2个平衡阀就会自动压死。不管是调冷水还是热水都没有水.

2)水温变化,30秒后加水阀关闭,回水阀打开继续调温,不会停止或报警提示;If the water runs out, two balance valves on the basic water station will work then it will be no more water whatever it’s hot or cold.

19、福建的供水为什么会发生瞬间压力上升、把平衡阀顶开?拆除止回阀后情况如何?

这个问题如上所述:就是无塔恒压供给造成的,在停止供水的瞬间、由于水塔压力过高(高的时候能达到1MP),把平衡阀顶开了、解决方法就是:在冷水进水做个气动蝶阀(实现供水启动的时候蝶阀打开,供水关闭的时候蝶阀关闭,来切断无塔恒压瞬间给供水的增压)

Why the pressure rises sharply? If we open the balance valve, unload the non-return flap valve, what it will be?

To sum up, it owns to the system of constant water pressure without tower.

When it stops pumping, the pressure of water tower rises up to 1 MPA to open the balance valve. The solution is to install an air operated reed valve when add the cold water. (When the system starts, the valve opens to cut off the pressure from system constant pressure without tower.)

20、供水常见的故障有哪些?如何排除?

调温不正常,定位器不好,回水阀不好,平衡阀不好,管道堵塞;

温度不准,传感器坏;

流量不准,流量表坏;

加不进水,电磁阀或蝶阀坏;

What’s the ordinary failure when supplies the water. How to fix it?

Thermoregulation failure, check the locator, water returned valve, balance valve and dredge the pipe.

Temperature is not accurate. The sensor may be broken.

Flow is not accurate. The flow rate indicator is broken.

It can’t add in water. The valve is broken.

21、什么叫冰水?

1)皮革行业有时需要低温水(如16-20度)、假如在夏天、常温水也在20-30都、此事就需要加入冰水、才能配出需要的低温水。

2)低于10度的水称为冰水;

What is ice-cold water?

In tannery, sometimes it needs water in low temperature (16-20centigrade). When it’s summer, the common temperature of water is 20-30 centigrade, in this case, you need to add ice water to adjust to be ice-cold water.

The water that bellows 10 centigrade is our ice-cold water.

22、如何增加冰水功能?

正常的情况下、供水只是冷水与热水在配水、如果需要低温水、就需要冷水与冰水来配水、此时、就需要把热水管切换到冰水管上去、方法:在热水管与冰水管之间增加2个蝶阀进行切换、此外、我们的控制也要相应改变、增加冰水功能一般我们要加收4000元。

(说明:客户需要有制冰机、否则、不能实现)

How to add the function of ice-cold water?

In normal condition, water supply system is just to mix cold water and hot water. If you need ice cold water, then you need to mix cold water with ice. In this condition, you need to switch the hot water pipe to the ice water pipe. Solution: add two valves between hot water pipe line and cold water pipe line. Then our controlling system needs to be changed a little to adapt to the condition. We will charge about 700USD for adding this function of adding ice-cold water.

(Instruction: you need to be equipped with ice machine.)

23、供水工作时、管道内的压力是多少?

一般在0.25-0.35MP

What is the pressure inside the pipe when the water supply system is working.

Usually it’s 0.25-0.35Mpa.

24、供水是否一定需要用水泵?

供水水泵是用来增压的、如果客户是无塔恒压系统的、水管压力在0.25MP以上的、可以不要用水泵,改做个气动蝶阀即可、

Is water pump essential to water supply system?

The water pump is used to add pressure. If you use constant pressure system without tower and the pressure is above 0.25MP, then the water pump is not essential. You could use air operated reed valve as a replacement.

25、工厂下班后要关闭供水吗?如果要关闭、怎样操作?

下班最好是关闭电脑,直接到基站的位置关闭开关即可

Should we shut down the water supply system when we leave the factory? How to turn it off?

It’s better to shut down the computer when you leave the factory. You can go to the basic station to turn it off.

26、供水的回水为什么要回入热水箱?回入冷水池可以吗?

只有调温的时候才会回水,调温的时候水也是热的,考虑到不浪费能源、回到热水箱是最好的、至于回入冷水箱,那是万万不可以的、那样会把冷水的箱的温度提高。配不出需要的温度。

Why the returned water must be guide into the hot water tank? Is it OK to be guided into the cold water tank?

It is because only when we adjusting the temperature, it yields returned water and the water is hot. Taking energy contamination into consideration, it’s better to make it into hot water tank. It’s forbidden to lead it into cold water tank because it will warm up the cold water.

27、供水的回水为什么要在最后一个转鼓开始?可以提前吗?

原则上不可以、如果提前、最前面的转鼓温度会不稳定、\

Why the returning of water should be start from the last drum?

Technically, if it starts from the last second, the temperature of the former drums will not be stable.

28、有的供水开启时声音很响、正常吗?如何消除?

一般不会、但有的工厂把管道悬挂在房梁上、会造成响声、解决方法:1)可以在回水阀上加个可调节流阀

1) 加固管道固定、或改从地面走。

Is it normal that some water supply system make large noise when it is turned on? How to eliminate the noise?

It hardly makes noise however, some factories put pipe on the beam which makes noise. The solution is to add an adjustable restrictive valve or to fix tight of the pipe or change the pipe line from on the beam to on the ground.

29、为什么我们一定要求客户用我们的蝶阀?

目前市场国产蝶阀质量次的太多、一旦坏了、客户总是讲我们的系统不好;此外、蝶阀坏了、维修很麻烦;经常的维修、客户还会对我们的影响不好、所以、工厂坚决杜绝客户自己配蝶阀、如果一定要配、要把臭话说在前面。

Why we ask our customer to use our butterfly valve?

So far the quality of valve varies. Once it is broken, it is always wrongly owed to the system. Besides, the fixation is a trouble which affects our credit. So we strictly forbid other kinds of valve. If you insist, you should take risk.

30、供水各种不同的口径、加水流量各是多少?

50口径的大概在25M3/H  65口径的大概在40M3/H  80口径的大概在60M3/H  100口径的大概在110M3/H

What is the flow when adding water considering different size of water supply system?

For size 50, 25M/3H; for 65 40M/3H, for size 80, 60M/3H, for size 100, 110M/3H

31、一台标准配置的供水共有多少部件组成?

1)基本站:包含2台增压水泵,2个平衡阀,1个混合阀,2个止回阀,2个过滤阀,1个流量计,4个压力表,3个温度表

2)控制站:1个电脑箱、1
