雕刻机专用真空泵选型怎么选呢?下面来了解一下几个重点。

How to choose the vacuum pump for carving machine? Here are a few key points.

一、常温作业介质(0-50℃),单纯抽水或溶液,不必水气两用,但要求具有自吸能力,并对流量和输出压力有要求。

I. normal temperature working medium (0-50 ℃), pure water pumping or solution, without water and gas dual-use, but with self-priming capacity and requirements for flow and output pressure.

阐明:抽的作业介质是水、非油性、不是强腐蚀的液体等溶液(不能含有固体颗粒等)、有必要有自吸功用。

It is clarified that the working medium of pumping is water, non oil, non strongly corrosive liquid and other solutions (without solid particles, etc.), so it is necessary to have self-priming function.

二、常温作业介质(0-50℃),需求抽水或气体(可能水气混合或空转、干转场合),垂青体积、噪音、接连运用等功用。

II. Normal temperature working medium (0-50 ℃), water pumping or gas demand (possible water gas mixing or idling, dry running occasions), vertical volume, noise, continuous use and other functions.

阐明:要求水气两用、能够长时间干转、不损坏泵;24小时接连运转;体积特别小、噪音低,但对流量、压力要求不高。

Clarification: it is required that water and gas can be used for both purposes, dry running for a long time without damaging the pump, continuous running for 24 hours, small volume and low noise, but not high flow and pressure requirements.

1、用微型泵抽气或抽真空,但有时会有液态水进入泵腔。

1. Use a micro pump to pump air or vacuum, but sometimes liquid water will enter the pump cavity.

2、要求微型泵既能抽气又能抽水。

2. The micro pump is required to be able to pump both air and water.

3、用微型泵抽水,但有些时候可能泵没有水可抽,处于“干转”状况。

3. Use a micro pump to pump water, but sometimes there may be no water to pump, which is in the "dry running" condition.

某些传统水泵害怕“干转”,“干转”乃至会损坏泵。而WKA系列产品本质上是一种复合功用泵,它集成了真空泵和水泵的功用,有人把它叫作“真空水泵”。因而,在没有水的情况下,它会抽真空,有水的时候它就抽水。无论是抽气状况仍是抽水状况,都归于正常作业领域,也就无所谓“干转”损害。

Some traditional pumps are afraid of "dry running", "dry running" and even damage the pump. WKA series of products are essentially a kind of composite function pump, which integrates the functions of vacuum pump and water pump. Some people call it "vacuum pump". Therefore, in the absence of water, it will vacuum, when there is water, it will pump. Whether it is pumping or pumping, it belongs to the normal operation field, so there is no "dry transfer" damage.

4、主要用微型泵抽水,但不期望在抽水前靠人工加“引水”(有些水泵在作业前需求人工参加一些“引水”,这样泵才能把低处的水抽上来,不然泵无法抽水乃至损坏),即期望泵有“自吸”功用。这时就能够选PHW、WKA系列产品,它们的利益就在于:没有接触到水时,它就抽真空,构成真空后靠气压把水压上来,而后开始抽水。

4. It is mainly used to pump water with micro pump, but it is not expected to add "water diversion" manually before pumping (some pumps need to participate in some "water diversion" manually before operation, so that the pump can pump up the water at the lower place, otherwise the pump cannot pump water or even damage), and it is expected that the pump has the function of "self-priming" at present. At this time, PHW and WKA series products can be selected. Their benefits lie in that when they are not in contact with water, they vacuumize, form a vacuum and then rely on air pressure to raise the water pressure, and then start pumping.

三、高温作业介质(0-100℃),比如用微型水泵来进行水循环散热、水冷却,或者抽高温、高温水蒸气、高温液体等,就有必要用微型水泵(高温型)才行:

3. High temperature working medium (0-100 ℃), such as using micro water pump for water circulation and cooling, or pumping high temperature, high temperature steam, high temperature liquid, etc., it is necessary to use micro water pump (high temperature type):

1.温度在:50-80℃之间,能够选用微型水气两用泵WKA系列高温介质型,最高耐温温度就是80℃或100℃;

1. The temperature is between 50-80 ℃, the high temperature medium type of WKA series of micro water gas dual-purpose pump can be selected, and the maximum temperature resistance is 80 ℃ or 100 ℃;

2.假如温度在:50-100℃之间,就有必要选用WKA系列高温介质型,最高耐温温度就是100℃;

2. If the temperature is between 50-100 ℃, it is necessary to select WKA series high temperature medium type, and the maximum temperature resistance is 100 ℃;

四、对流量有较大要求(超过20升/分钟),但介质中含有少数油分、固体颗粒、残渣等。

IV. there is a large demand for flow (more than 20 L / min), but the medium contains a small amount of oil, solid particles, residues, etc.

阐明:要抽的介质中,

Elucidation: in the medium to be pumped,

1、包括数量较少的、直径较小的软性固体颗粒(如鱼类粪便、污水淤泥、残渣等),但黏度不能太大,且最好不要有头发一类的环绕物;

1. It includes a small number of soft solid particles with small diameter (such as fish manure, sewage sludge, residue, etc.), but the viscosity should not be too large, and it is better not to have the surrounding materials such as hair;

2、答应作业介质中含有少数的油分(例如污水面上漂浮的少数油),但不能全部是油!

2. It is allowed that the working medium contains a small amount of oil (such as a small amount of oil floating on the sewage surface), but not all of it is oil!

3、流量要求较大(超过20升/分钟):

3. Large flow requirements (more than 20 L / min):

雕刻机真空泵在正常运转中需注意以下事项:

The vacuum pump of engraving machine should pay attention to the following matters during normal operation:

1. 新上设备内易有杂质,吸入泵内会形成叶轮及泵壳损坏。

1. The new equipment is easy to have impurities, and the impeller and pump shell will be damaged in the suction pump.

2. 装置要水平结实,管路不要重压在泵上。

2. The device shall be level and firm, and the pipeline shall not be pressed on the pump.

3. 开启时泵腔内应有一定量的循环液(液体占泵腔体积2/3,不宜过多或过少),不然易形成机械密封损坏。

3. When the pump is opened, there should be a certain amount of circulating liquid in the pump cavity (the liquid accounts for 2 / 3 of the pump cavity volume, which should not be too much or too little), otherwise it is easy to form mechanical seal damage.

4. 供水方法最好用闭路循环系统或水箱平稳常压自循环供水,不能正压供水或运用自来水管路供水。

4. The water supply method is best to use closed-circuit circulation system or water tank to supply water steadily and normally, and it is not allowed to use positive pressure water supply or tap water pipeline.

5. 挑选流动性较好,受温度影响较小的循环液(最好用水做循环液)。

5. Select circulating liquid with good fluidity and little influence of temperature (water is the best circulating liquid).

6. 定时查看轴承,避免缺油形成设备损坏。

6. Check the bearing regularly to avoid equipment damage due to oil shortage.

7. 泵排气口的管路不得高于1米 (从法兰口算起)。

7. The pipeline of the pump exhaust port shall not be higher than 1 m (calculated from the flange port).

8. 泵腔内有爆炸声时阐明已达到极限真空并发生气蚀,此刻应打开进气阀门通入适量大气。

8. When there is explosion sound in the pump cavity, it is clarified that the limit vacuum has been reached and cavitation occurs. At this moment, the air inlet valve shall be opened to enter a proper amount of atmosphere.

9. 配用电机11千瓦以上的泵,应装备降压发动。

9. Pumps equipped with motors above 11kw shall be equipped with step-down motors.

10.泵停止运行时,有必要封闭进泵循环水入口处的阀门,冬天应将泵腔内循环水放空。

11.设备作业环境温度不宜过高,设备禁止暴晒。

11. The operating environment temperature of the equipment shall not be too high, and the equipment shall not be exposed to the sun.
