英國GRIMM格林進(jìn)口水環(huán)式真空泵概述：

進(jìn)口水環(huán)真空泵及壓縮機(jī)是用來抽吸或壓送氣體和其它無腐蝕性、不溶于水、不含固體顆粒的氣體，以便在密閉容器中形成真空或壓力，滿足工藝流程要求，吸入或壓送的氣體中允許混有少量的液體。

英國GRIMM格林進(jìn)口水環(huán)式真空泵工作原理：

葉輪偏心地安裝在泵體內(nèi)，因此當(dāng)葉輪旋轉(zhuǎn)時，水受離心力的作用而在泵體內(nèi)壁形成一旋轉(zhuǎn)水環(huán)，水環(huán)上部內(nèi)表面與輪轂相切沿箭頭方向旋轉(zhuǎn)，在前半轉(zhuǎn)過程中，水環(huán)內(nèi)表面逐漸與輪轂脫離，因此在葉輪葉片間與水環(huán)形成封閉空間，隨著葉輪的旋轉(zhuǎn)，該空間逐漸擴(kuò)大，空間氣體壓力降低，氣體被及入空間；在后半轉(zhuǎn)過程中，水環(huán)內(nèi)表面漸漸與輪轂靠近，葉片間的空間逐漸縮小，空間氣體壓力升高，高于排氣口時，葉片間的氣體被排出。如此葉輪每轉(zhuǎn)動一周，葉片間的空間吸排一次，許多空間不停地工作，泵就連續(xù)不斷地抽吸或壓送氣體。

由于在工作過程中，做功產(chǎn)生熱量，會使工作水環(huán)發(fā)熱，同時一部分水和氣體一起被排走，因此，在工作過程中，必須不斷地給泵供水，以冷卻和補(bǔ)充泵內(nèi)消耗的水，滿足泵的工作要求。

當(dāng)泵排出的氣體不再利用時，在泵排氣一端接有氣水分離器（可自己制作一水箱代替），廢水和所帶的部分水排入氣水分離器后，氣水分離，氣體由排氣管排出，留下的水經(jīng)回水管供至泵內(nèi)繼續(xù)使用。隨著工作時間的延長，工作水溫度會不斷地升高，這時需從氣水分離器供水處供給一定的冷水（自來水），以降低工作水的溫度，保證泵能達(dá)到所要求的技術(shù)要求和指標(biāo)。

當(dāng)作為壓縮機(jī)使用時，泵排氣口接有氣水分離器，氣水混合物進(jìn)入氣水分離器后自動分離，氣體由排氣管輸送到所需系統(tǒng)而工作水經(jīng)過自動溢于開關(guān)放出，壓縮氣體時，工作水極易發(fā)熱，水由泵出口排出，溫度會變得較高，因此在氣水分離器的底部，要不斷地供給冷水，以補(bǔ)充被放走的熱水，同時起冷卻作用，使工作水溫度不致過高，從而保證壓縮機(jī)性能，達(dá)到技術(shù)指標(biāo)，滿足工藝要求。

英國GRIMM格林進(jìn)口水環(huán)式真空泵結(jié)構(gòu)說明：

進(jìn)口水環(huán)式真空泵由泵體、兩個端蓋、葉輪、軸等部件組成。進(jìn)氣管和排氣管通過安裝在端蓋上的園盤上的吸氣孔和排氣孔與泵腔相連，軸偏心地安裝在泵體中，葉輪用平鍵固定在軸上。水環(huán)式真空泵兩端面的總間隙由泵體和園盤之間的墊來調(diào)整，葉輪與端蓋上的園盤之間的間隙由軸套（SK-1.5/3/6）或背帽（SK-12/20/30）推動葉輪來調(diào)整，而SK-42以上軸與葉輪為過盈配合，此間隙由前端定位時確定，SK-42/60/85/120無軸套，其余結(jié)構(gòu)與SK-6/12/20/30相同。葉輪兩端面與端蓋園盤的間隙決定氣體在泵腔內(nèi)由進(jìn)氣口至排氣口流動中損失的大小及極限壓力。

進(jìn)口水環(huán)式真空泵填料安裝在兩端蓋內(nèi)，密封不經(jīng)由端蓋中的小孔進(jìn)入填料中，冷卻填料及加強(qiáng)密封效果。葉輪形成水環(huán)所需的補(bǔ)充水由供水管供給，供水管可與氣水分離器連在一起循環(huán)供水。

SK型水環(huán)式真空泵密封形式采用機(jī)械密封，機(jī)械密封安裝在填料空腔里，填料省略。填料壓蓋換成機(jī)械密封壓蓋，其余結(jié)構(gòu)相同。

軸承由園螺母固定在軸上。

進(jìn)口水環(huán)式真空泵在端蓋上安裝有園盤，園盤上設(shè)有吸、排氣孔和橡膠球閥。橡膠球閥的作用是當(dāng)葉輪葉片間的氣體壓力達(dá)到排氣壓力時，在排氣口以前就將氣體排出，減少了因氣體壓力過大而消耗的功率，從而降低功率消耗。

英國GRIMM格林進(jìn)口水環(huán)式真空泵適用范圍：

廣泛應(yīng)用于機(jī)械、石油、化工、制藥、食品、陶瓷、制糖、印染、冶金等行業(yè)。由于在工作過程中，該泵對氣體的壓縮過程是在等溫狀態(tài)下進(jìn)行的，因此在壓送和抽吸易燃、易爆氣體時，不易發(fā)生危險，所以其應(yīng)用更加廣泛。

UK GRIMMImported water ring vacuum pumpsummary:

Imported water ring vacuum pumps and compressors are used to pump or press gas and other gases without corrosion, insoluble and non solid particles, so as to form a vacuum or pressure in a closed container to meet the requirements of the process flow. A small amount of liquid is allowed to be mixed in the gas that is inhaled or pressed.

UK GRIMMImported water ring vacuum pumpworking principle:

The impeller is eccentrically installed in the pump body, so when the impeller rotates, the water is driven by the centrifugal force and forms a rotating water ring on the inner wall of the pump body. The inner surface of the upper part of the water ring rotates along the arrow direction tangent to the hub, and the inner surface of the water ring is gradually separated from the hub during the first half process, because this forms the closure between the impeller blades and the water ring. In space, with the rotation of the impeller, the space gradually expands, the pressure of the space gas is reduced and the gas is entered into the space. In the back half process, the inner surface of the water ring is gradually close to the hub, the space between the blades gradually diminishing, the pressure of the space gas rises, and the gas between the blades is discharged when it is higher than the vent. Every time the impeller rotates one week, the space between the blades is sucked up once, and many spaces work continuously, and the pump continuously suck or pressurized the gas.

In the process of work, doing work to produce heat, will make the working water ring heat, while a part of the water and gas are discharged together, therefore, in the working process, the pump must be continuously supplied to the pump to cool and supplement the water consumed in the pump to meet the work requirements of the pump.

When the gas of the pump is no longer used, there is a gas water separator at the end of the pump (which can be replaced by a water tank.) the waste water and the part of the water are discharged into the gas water separator. The gas and water are separated, the gas is discharged from the exhaust pipe, and the water left behind is supplied to the pump to continue to use. With the prolongation of working time, the temperature of the working water will increase continuously. At this time, a certain cold water (tap water) should be supplied from the water separator of the gas water separator in order to reduce the temperature of the working water, so as to ensure that the pump can meet the required technical requirements and indicators.

When used as compressor, the exhaust port of the pump is connected with a gas water separator, the gas water mixture enters the gas water separator and automatically separates. The gas is transported from the exhaust pipe to the required system and the working water is discharged automatically through the switch. When the gas is compressed, the working water is extremely hot, the water is discharged from the pump outlet and the temperature will become higher because of the water. At the bottom of the gas water separator, it is necessary to supply cold water continuously to supplement the hot water that has been released, and to cool the working water, so that the working water temperature is not too high, thus ensuring the performance of the compressor, reaching the technical index, and meeting the technical requirements.

UK GRIMMImported water ring vacuum pumpstructure description:

The imported water ring vacuum pump is composed of pump body, two end covers, impeller, shaft and other components. The intake and exhaust pipes are connected to the pump cavity by the suction hole and the exhaust hole installed on the disc of the end cover. The shaft is installed in the pump body eccentrically, and the impeller is fixed on the shaft with a flat key. The total gap between the two end surfaces of the water ring vacuum pump is adjusted by the cushion between the pump body and the disc. The clearance between the impeller and the end cap is adjusted by the SK-1.5/3/6 or the back cap (SK-12/20/30), and the above axis of the SK-42 is in interference with the impeller. The gap is determined by the front end positioning, and the SK-42/60/85/120 is no shaft. The rest of the structure is the same as that of SK-6/12/20/30. The clearance between the two end faces of the impeller and the end plate determines the size and ultimate pressure of the gas flow in the pump chamber from the intake port to the exhaust port.

The packing of the imported water ring vacuum pump is installed in the two ends of the cover, and the sealing is not entered through the small hole in the end cover, and the cooling filler is reinforced and the sealing effect is enhanced. The replenish water needed for the impeller to form a water ring is supplied by the water supply pipe, and the water supply pipe can be connected with the gas water separator to circulate water supply.

The SK type water ring vacuum pump adopts the mechanical seal in the form of sealing, and the mechanical seal is installed in the packing cavity, and the packing is omitted. The packing gland is replaced by a mechanical seal gland and the rest of the structure is the same.

The bearing is fixed on the shaft by the nut of the garden.

The imported water ring vacuum pump is equipped with a garden disk on the end cover, and there are suction, vent holes and rubber ball valves on the orchard. The effect of the rubber ball valve is that when the gas pressure between the blades of the impeller reaches the exhaust pressure, the gas is discharged before the vent, reducing the power consumed by the excessive pressure of the gas, thus reducing the power consumption.

UK GRIMMImported water ring vacuum pumpscope of application:

Widely used in machinery, petroleum, chemical, pharmaceutical, food, ceramics, sugar, printing and dyeing, metallurgy and other industries. In the process of working, the compression process of the pump is carried out in an isothermal state, so it is not easy to be dangerous when flammable and explosive gas is pressed and pumped, so its application is more extensive.
