地下室設計了衛(wèi)生間，廚房，洗衣房等有用水需求的場所，就需要用污水提升泵來進行排水，完善我們的地下室排水系統(tǒng)，那么，作為污水提升泵的核心裝置—電機，我們今天來從電機的位置，電機的轉速，密封方式，外殼材質，散熱方式和電機控制形式來分析一下污水提升泵的電機。

The basement is designed with toilets, kitchens, laundries and other places with water demand, so we need to use the sewage lift pump to drain water and improve our basement drainage system. Then, as the core device of the sewage lift pump - motor, today we will start from the position, speed, sealing mode and shell material of the motor, Heat dissipation mode and motor control form to analyze the motor of sewage lifting pump.

污水提升泵中電機的位置一般就兩種，內置和外置，內置是指電機位于機器水箱的內部，與污水進行直接的而解除，外置就是處于水箱的外部，不與污水進行直接的接觸，相比內置泵而言，外置泵對于技術的要求，裝配精度以及密封性要求更高，因而造價更高，并且外置泵在后期的維護方面更加方便，只需在外部檢查電機即可，無需打開箱體接觸污水，并且外置泵箱體密封效果會更好，對于異味的散發(fā)和蚊蟲的滋生方面防護的更好。

There are generally two positions of the motor in the sewage lifting pump, built-in and external. The built-in refers to that the motor is located inside the machine water tank and is directly released from the sewage. The external is located outside the water tank without direct contact with the sewage. Compared with the built-in pump, the external pump has higher requirements for technology, assembly accuracy and sealing, so the cost is higher, Moreover, the external pump is more convenient in the later maintenance. It only needs to check the motor externally without opening the box to contact the sewage. Moreover, the sealing effect of the external pump box will be better, and the protection against the emission of peculiar smell and the breeding of mosquitoes will be better.

電機轉速就是指電機的額定轉速，是指額定功率下的轉速，在轉矩相同的情況下，轉速越快，機器做功越快，那同一時間內，機器做的功就多，機器的效率就高，而機器的效率是電機產(chǎn)品的重要性指標，特別在國家節(jié)能減排政策的導向下，高效節(jié)能電機逐步成為一種趨勢，像是澤德采用德國EMGR電機，電機材料利用率高，消耗在材料中的發(fā)熱損耗也相對較少，澤德的電機轉速分為兩種，四級電機的1轉和二級電機2800轉，轉速越高，能將水提升的高度也就越高，但是這也并不是說明轉速越快越好，在滿足揚程(輸出功率相同)的前提下，轉速低的，能效比高，聲音小，對于機器的使用壽命更有益處。

Motor speed refers to the rated speed of the motor, which refers to the speed under the rated power. Under the same torque, the faster the speed, the faster the machine does work. At the same time, the more work the machine does, the higher the efficiency of the machine. And the efficiency of the machine is an important index of motor products, especially under the guidance of the national energy conservation and emission reduction policy, High efficiency and energy-saving motors have gradually become a trend. For example, Zeder adopts German emgr motor, which has high material utilization rate and relatively less heat loss consumed in materials. Zeder's motor speed is divided into two types: one revolution of four-stage motor and 2800 revolutions of two-stage motor. The higher the speed, the higher the height of water lifting, but this does not mean that the faster the speed, the better, On the premise of satisfying the head (the same output power), low speed, high energy efficiency ratio and low sound are more beneficial to the service life of the machine.

一般電機的密封方式都會采用機械密封的形式，讓機器在運行的時候也保持電機與水的分離，避免二者短兵相見導致的機器失靈，但是，現(xiàn)在市面上也會有價格較高的產(chǎn)品，它們除了采用傳統(tǒng)的機械密封外，還會加一個雙重保護，就是油腔密封，就是在機械密封的外層放置一些礦物質油，讓運轉沉浸在油中，起到潤滑和密封的雙重作用，并且在機械密封產(chǎn)生問題的時候，還能起到對電機的保護作用，這樣的雙重保險也就奠定了其價格的高位。

Generally, the sealing method of the motor will adopt the form of mechanical seal, so that the machine can keep the separation of the motor and water during operation, so as to avoid the machine failure caused by the short encounter between the two. However, there will also be products with higher prices on the market. In addition to the traditional mechanical seal, they will also add a double protection, namely oil cavity seal, It is to place some mineral oil on the outer layer of the mechanical seal to immerse the operation in the oil, which plays a dual role of lubrication and sealing, and can also play a protective role for the motor when the mechanical seal has problems. Such dual insurance has also laid a high price.

電機外殼顧名思義就是包裹著電機的一層保護套，它的材質對于電機的運行性能起著重要的作用?，F(xiàn)在市面上電機外殼的材質分為：塑料，不銹鋼，鑄鐵和鑄鋁合金這四種，四者在價格方面的優(yōu)勢如下：塑料不銹鋼鑄鐵鑄鋁合金，而作為電機的外殼重要的就是幫助電機散出電機在工作時產(chǎn)生的巨大的熱量，而四者的散熱性能如下塑料(導熱系數(shù)0.17-0.5左右)不銹鋼(導熱系數(shù)16-20左右)鑄鐵(導熱系數(shù)42-90左右)鑄鋁合金(導熱系數(shù)138-147左右)，這就很直觀的看出鑄鋁合金材質的電機外殼是勝在了哪里。

As the name suggests, the motor shell is a protective sleeve wrapped around the motor. Its material plays an important role in the operation performance of the motor. At present, the materials of motor shell on the market are divided into plastic, stainless steel, cast iron and cast aluminum alloy. The price advantages of the four are as follows: plastic, stainless steel, cast iron and cast aluminum alloy. As the shell of motor, it is important to help the motor dissipate the huge heat generated by the motor during operation, The heat dissipation performance of the four is as follows: plastic (thermal conductivity of about 0.17-0.5), stainless steel (thermal conductivity of about 16-20), cast iron (thermal conductivity of about 42-90) and cast aluminum alloy (thermal conductivity of about 138-147), which intuitively shows where the motor shell made of cast aluminum alloy wins.

一般我們看見的電機外殼都是光滑的，這種基本就是要依靠材質的本身的散熱性或是放置在有水的環(huán)境中來排出電機工作時產(chǎn)生的大量的熱量，但是也有一些價格較高的外置泵機器會把電機外殼的表面做成鰭翼狀，這樣就增加了其與空氣的接觸面積，使得散熱效果增加兩倍以上，保證電機在干式運轉的情況下，也能有良好的散熱性能，這樣會使得機器的運行更加穩(wěn)定。

Generally, the motor shell we see is smooth. This basically depends on the heat dissipation of the material itself or placed in the environment with water to discharge a large amount of heat generated during the operation of the motor. However, some expensive external pump machines will make the surface of the motor shell into fin wing shape, which increases its contact area with the air, The heat dissipation effect is more than doubled to ensure that the motor can also have good heat dissipation performance under the condition of dry operation, which will make the operation of the machine more stable.

現(xiàn)在我們看見的市面上的污水提升泵的控制形式就是兩種，一種是小型機器的集成電路板，整個控制系統(tǒng)就是在機器的內部，一般處于電機的上面，這個電路板就相當于是機器的大腦，機器的啟停全靠它來控制;另一種就是大型機器中的控制器，這種一般會將機器和控制器分開來，控制器是單獨的一個設備，并配置液晶屏，可以控制機器的啟停液位和報警液位，可以對機器的各種參數(shù)進行調節(jié)，更加智能，因而造價當然也就更貴，像是澤德Kompaktboy和ZPG雨水泵系列配置的ZPS控制器，內置強大的MCU芯片，除了調節(jié)水位外，還能了解機器的運行時間，啟動次數(shù)，電流，維護周期等參數(shù)，非常便攜。

Now we can see that there are two control forms of sewage lift pump on the market. One is the integrated circuit board of small machine. The whole control system is inside the machine, usually above the motor. This circuit board is equivalent to the brain of the machine, and the start and stop of the machine are controlled by it; The other is the controller in large machines, which generally separates the machine from the controller. The controller is a separate device and is equipped with LCD screen, which can control the start and stop liquid level and alarm liquid level of the machine, and can adjust various parameters of the machine. It is more intelligent, so the cost is certainly more expensive, For example, the Zps controller of Zede kompaktboy and ZPG rainwater pump series is equipped with a powerful MCU chip. In addition to adjusting the water level, it can also understand the running time, starting times, current, maintenance cycle and other parameters of the machine. It is very portable.

所以說，一臺機器的價格貴在哪里，從電機的這些方面就能窺見一些，當然，我們還是要根據(jù)自身情況來選擇適合的機器。

Therefore, the price of a machine can be seen from these aspects of the motor. Of course, we still have to choose the appropriate machine according to our own situation.
