自吸泵與增壓泵的區(qū)別

　　自吸泵包括增壓泵，但增壓泵不一定屬于自吸泵。自吸泵與增壓泵的區(qū)別就是自吸泵具有自吸和增壓的功能、而增壓泵是只具有增壓的功能、它沒有自吸能力、必須要水能流到泵里面來才能起到增壓的作用。

　　換句話說：自吸泵可以用來增壓，但增壓泵不能替代自吸泵。　　

二、分析

　　區(qū)分自吸泵和增壓泵之前，要對自吸泵和增壓泵的定義重復一下。

　　1、自吸泵

　　是指**次灌水后，以后再使用就無需再次灌水即可啟動運行，自吸泵是否自吸要看停機后葉輪是否浸入水中，自吸泵就是因為有獨特的泵腔結構而可以保證每次停機后葉輪都可以浸入水中才保證了其自吸;

　　自吸泵：適用于清水、海水及帶有酸、堿度的化工介質(zhì)液體和帶有一般糊狀的漿料。可和任何型號、規(guī)格的壓濾機配套使用，將漿料送給壓濾機時進行壓濾的*理想配套泵種。

　　2、增壓泵

　　是泛指能對管路的液體進行提供額外壓力的泵的統(tǒng)稱，并不指某一種類型的泵，增壓泵可以是管道泵、離心泵、污水泵、自吸泵、多級泵等類型泵。如果要讓非自吸式的增壓泵達到自吸效果(泵位于水池上方)，可以在泵的吸入口加裝底閥即可。

　　增壓泵用途主要有：熱水器增壓用、高樓低水壓、桑拿浴、洗浴等加壓用、公寓*上層水壓不足的加壓、太陽能自動增壓、反滲透凈水器增壓用等。

　　三、自吸泵與增壓泵的區(qū)別，何時選擇自吸增壓泵比較好?

　　下列情況盡量選擇自吸式結構的增壓泵以提高使用性或安全性：

　　1、泵位于水池(裝液體的設備)上方;

　　2、所抽液體有毒或有異味;

　　3、溫度較高(溫度過高會影響自吸高度)。

　　四、增壓泵和自吸泵區(qū)別具體在哪里?

　　**、兩個泵都是可以增壓，一個是管道中間的水位高于泵體的(增壓泵)一個是管道中間的水位低于泵體的(自吸泵)**不要在自來水管線上直接裝自吸泵，有可能會把水表的玻璃吸碎的。

　　第二、如果水沒有斷流情況可以使增壓泵，如果經(jīng)常斷流就要準備個容器了(水池、水罐等)，容器上可以裝排水管就還可以使增壓泵，不能裝排水管就只能裝自吸泵。

　　增壓泵是在自吸泵的基礎上安裝了恒壓裝置。也就是說能夠保持水管內(nèi)水壓保持一個相對平均的壓力，但是因為結構簡單，控制起來不是很好用，容易把水泵燒掉。

　　Difference between self priming pump and booster pump

　　Self priming pump includes booster pump, but booster pump does not necessarily belong to self priming pump. The difference between the self-priming pump and the booster pump is that the self-priming pump has the functions of self-priming and pressurization, while the booster pump only has the function of pressurization. It has no self-priming capacity. It can only play the role of pressurization when water can flow into the pump.

　　In other words: the self-priming pump can be used to pressurize, but the booster pump cannot replace the self-priming pump.

　　2、 Analysis

　　Before distinguishing between self-priming pump and booster pump, repeat the definition of self-priming pump and booster pump.

　　1. Self priming pump

　　It means that after the first water filling, the self-priming pump can be started without water filling again. Whether the self-priming pump is self-priming depends on whether the impeller is immersed in the water after the shutdown. The self-priming pump can ensure that the impeller can be immersed in the water after each shutdown because of its unique pump cavity structure;

　　Self priming pump

　　Self priming pump: suitable for clear water, sea water, chemical medium liquid with acid and alkalinity and slurry with general paste. It can be used with filter press of any model and specification. It is the most ideal matching pump for pressure filtration when the slurry is sent to the filter press.

　　2. Booster pump

　　It generally refers to the pumps that can provide additional pressure for the liquid in the pipeline. It does not refer to a certain type of pump. Booster pumps can be pipeline pumps, centrifugal pumps, sewage pumps, self-priming pumps, multi-stage pumps and other types of pumps. If you want to make the non self-priming booster pump achieve self-priming effect (the pump is located above the pool), you can install a bottom valve at the suction port of the pump.

　　Booster pump

　　The booster pump is mainly used for water heater pressurization, high-rise buildings with low water pressure, sauna, bathing and other pressurization, pressurization with insufficient water pressure on the top floor of the apartment, solar automatic pressurization, reverse osmosis water purifier pressurization, etc.

　　3、 The difference between self-priming pump and booster pump. When is it better to choose self-priming booster pump?

　　The booster pump with self-priming structure shall be selected as far as possible to improve usability or safety in the following cases:

　　1. The pump is located above the pool (equipment containing liquid);

　　2. The liquid pumped is poisonous or has peculiar smell;

　　3. High temperature (too high temperature will affect the self-priming height).

　　4、 What is the difference between booster pump and self-priming pump?

　　First, both pumps can be pressurized. One is that the water level in the middle of the pipeline is higher than the pump body (booster pump) and the other is that the water level in the middle of the pipeline is lower than the pump body (self-priming pump). It is best not to install a self-priming pump directly on the tap water pipeline, which may break the glass of the water meter.

　　Second, if the water is not cut off, the booster pump can be used. If the water is often cut off, a container (pool, water tank, etc.) should be prepared. If the container can be equipped with a drain pipe, the booster pump can also be used. If the drain pipe cannot be installed, the self-priming pump can only be installed.

　　Booster pump is a constant pressure device installed on the basis of self-priming pump. That is to say, it can keep the water pressure in the water pipe at a relatively average pressure, but because of its simple structure, it is not easy to control, so it is easy to burn the water pump.
