英国GRIMM格林进口水环式真空泵概述: 

          进口水环真空泵及压缩机是用来抽吸或压送气体和其它无腐蚀性、不溶于水、不含固体颗粒的气体,以便在密闭容器中形成真空或压力,满足工艺流程要求,吸入或压送的气体中允许混有少量的液体。

英国GRIMM格林进口水环式真空泵工作原理: 

              叶轮偏心地安装在泵体内,因此当叶轮旋转时,水受离心力的作用而在泵体内壁形成一旋转水环,水环上部内表面与轮毂相切沿箭头方向旋转,在前半转过程中,水环内表面逐渐与轮毂脱离,因此在叶轮叶片间与水环形成封闭空间,随着叶轮的旋转,该空间逐渐扩大,空间气体压力降低,气体被及入空间;在后半转过程中,水环内表面渐渐与轮毂靠近,叶片间的空间逐渐缩小,空间气体压力升高,高于排气口时,叶片间的气体被排出。如此叶轮每转动一周,叶片间的空间吸排一次,许多空间不停地工作,泵就连续不断地抽吸或压送气体。

     由于在工作过程中,做功产生热量,会使工作水环发热,同时一部分水和气体一起被排走,因此,在工作过程中,必须不断地给泵供水,以冷却和补充泵内消耗的水,满足泵的工作要求。

     当泵排出的气体不再利用时,在泵排气一端接有气水分离器(可自己制作一水箱代替),废水和所带的部分水排入气水分离器后,气水分离,气体由排气管排出,留下的水经回水管供至泵内继续使用。随着工作时间的延长,工作水温度会不断地升高,这时需从气水分离器供水处供给一定的冷水(自来水),以降低工作水的温度,保证泵能达到所要求的技术要求和指标。

     当作为压缩机使用时,泵排气口接有气水分离器,气水混合物进入气水分离器后自动分离,气体由排气管输送到所需系统而工作水经过自动溢于开关放出,压缩气体时,工作水极易发热,水由泵出口排出,温度会变得较高,因此在气水分离器的底部,要不断地供给冷水,以补充被放走的热水,同时起冷却作用,使工作水温度不致过高,从而保证压缩机性能,达到技术指标,满足工艺要求。

英国GRIMM格林进口水环式真空泵结构说明: 

          进口水环式真空泵由泵体、两个端盖、叶轮、轴等部件组成。进气管和排气管通过安装在端盖上的园盘上的吸气孔和排气孔与泵腔相连,轴偏心地安装在泵体中,叶轮用平键固定在轴上。水环式真空泵两端面的总间隙由泵体和园盘之间的垫来调整,叶轮与端盖上的园盘之间的间隙由轴套(SK-1.5/3/6)或背帽(SK-12/20/30)推动叶轮来调整,而SK-42以上轴与叶轮为过盈配合,此间隙由前端定位时确定,SK-42/60/85/120无轴套,其余结构与SK-6/12/20/30相同。叶轮两端面与端盖园盘的间隙决定气体在泵腔内由进气口至排气口流动中损失的大小及极限压力。

          进口水环式真空泵填料安装在两端盖内,密封不经由端盖中的小孔进入填料中,冷却填料及加强密封效果。叶轮形成水环所需的补充水由供水管供给,供水管可与气水分离器连在一起循环供水。

SK型水环式真空泵密封形式采用机械密封,机械密封安装在填料空腔里,填料省略。填料压盖换成机械密封压盖,其余结构相同。

轴承由园螺母固定在轴上。

         进口水环式真空泵在端盖上安装有园盘,园盘上设有吸、排气孔和橡胶球阀。橡胶球阀的作用是当叶轮叶片间的气体压力达到排气压力时,在排气口以前就将气体排出,减少了因气体压力过大而消耗的功率,从而降低功率消耗。

英国GRIMM格林进口水环式真空泵适用范围: 

             广泛应用于机械、石油、化工、制药、食品、陶瓷、制糖、印染、冶金等行业。由于在工作过程中,该泵对气体的压缩过程是在等温状态下进行的,因此在压送和抽吸易燃、易爆气体时,不易发生危险,所以其应用更加广泛。

UK GRIMM Imported water ring vacuum pump summary:

          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 GRIMM Imported water ring vacuum pump working 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 GRIMM Imported water ring vacuum pump structure 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 GRIMM Imported water ring vacuum pump technical parameter:

Maximum pumping capacity: 0.15-120m3/min

Water consumption: (4-5) ~ (220-260) L/min

Import and export caliber: 25-300mm

Limit vacuum degree: 0.091-0.098MPa

Speed: 590-2900r/min

UK GRIMM Imported water ring vacuum pump scope 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.
