         该系列泵是为满足输送有大颗粒及较为苛刻和重工位的需要而特殊设计，用于石油jing制、石油化工和hua学工业及其它地方输送石油及其产品、它完全符合美国石油学会AP1610规范。

         进口单级双吸流程泵具有可靠性高、使用寿命长、通用化程度高等特点，尤其是效率高更为突出。

英国GRIMM格林进口单级双吸流程泵结构特点：

         进口单级双吸流程泵是单级双吸两端支承式离心流程泵，泵壳径向部分。特别适用于输送高温高压以及易燃易爆或有毒的液体，其安装方式为水平中心线支承，以把热胀冷缩产生的变形及位移降低到zui低限度。泵体设计成双涡室，以平衡泵的径向力。

         泵靠有压液体流动可以自行排气，但泵体蜗壳上部和下部均留有脐子，当用户需要排气和放液时，可以开 ZG3/4"螺孔。在工作现场用丝堵拧上。

         泵的吸入口和排出口法兰均为垂直向上，与泵体铸成一体，其法兰尺寸和压力等级均等效采用美国全国标准学会(ANSI)标准等级。根据使用温度和材料类别不同，法兰zui高使用压力可达5MPa(约50kgf/cm2)左右。

         为了可靠，流程泵均使用铸钢壳体，其静水压试验为7MPa(约70kgf/cm2)。

         轴封腔(填料封)和泵盖是铸成一体的，它可以装填料密封及平衡型、波纹管或串联型的机械密封，腔外面铸有可供选者的水冷腔夹套，水冷夹套的配备必须是特别提出要求或者是输送介质为水质为水的温度超过66℃以及碳氢化合物温度超过150℃时用。当输送介质需要保温时，在其夹套内还可以通入低压蒸汽或其他保温介质。其静水压试验1MPa(约10kgf/cm2)冷却水进口接头ZG1/2"；在泵盖下方，出口接头ZG1/2"；在泵盖上方。蒸汽进口接头 ZG1/2"；在盖上方，出口接头 ZG1/2"；在泵盖下方。

         叶轮为整体铸造件，且随转子一起做动平衡，它与轴是用键传动，转子是两端支承。壳体密封环或叶轮密封环均为可更换的标准件，两者良好的匹配由材料及其不同硬度来保证。叶轮两端的密封环有意设计成大小不同的尺寸即靠止推轴承一侧的密封环稍小于另一侧，使泵造成轻微的轴向力，让轴永远处于受拉状态工作，避免转子的左右串动。

         泵两端是同样大小的轴承体，材料为铸钢和铸铁两种，用螺钉紧固在托架(瓦架)上，并用配合止口定位，靠联轴器端装一套径向轴承，另一端装两套背对背安装的推力球轴承，轴承采用甩油环润滑，油量适中，每个轴承体外铸有散热片，可供空气冷却(T≤120℃)，还可选用风扇冷却(T=120-260℃)和水冷却(T≥260℃)，其中风扇冷却尤为适用于缺水或水质差的地区。

         当泵轴承使用风扇冷却时，风扇将取代防尘盘的位置，这也是此种泵的独特之处。当泵轴承使用水冷却时，球轴承外面铸有水冷夹套。

         轴承体同时装有透明塑料圆形油标和油杯，以监视和控制油位，轴承体两端装有铜质防尘盘，伸向轴承压盖的内孔，既可以防止灰尘或水份进入，又可以防止油泄漏。当轴承万一破裂时，它还能起支承作用。

         为了检修不必坼卸吸入或吐出管路就很容易的坼出叶轮、轴承、轴封等。 单级双吸流程泵采用挠性膜片式加长联轴器部件，且与泵轴为锥型配合，坼装非常方便。

         泵的转向：从原动机往泵看为逆时针方向旋转。

UK GRIMM imported single stage double suction flow pump summary:

           Single stage double suction pump inlet flow, single-stage double suction centrifugal pump with two supports, is a British green company with single stage double suction pump design of the tenth edition of the API610, as the radial part of double support of high temperature heavy load design, installation for the central support, the pump body is a double volute chamber; double suction impeller, cavitation of small good balance, axial; import and export are up, convenient installation and maintenance; sealing and flushing system according to the API682 standard design, all sealing and flushing plan to install the API682 code.

        This series of pumps is to meet the needs of large particles and conveying a harsh and heavy work and special design, used in petroleum refining, petrochemical and chemical industries and other local transportation of petroleum and its products, it is fully in line with the American Petroleum Institute AP1610 specification.

        imported single stage double suction flow pump has the characteristics of high reliability, long service life and high degree of generalization, especially high efficiency.

UK GRIMM imported single stage double suction flow pump structure characteristics:

           The imported single stage double suction flow pump is a single stage double suction centrifugal pump with two ends supporting. The radial part of the pump shell. The utility model is especially suitable for conveying high temperature, high pressure, flammable and explosive or poisonous liquid, and the installation method is supported by a horizontal central line, so as to reduce the deformation and displacement caused by thermal expansion and cold contraction to a minimum. The pump body is designed with twin volute chambers to balance the radial forces of the pump.

         The pump can flow freely by the pressure liquid flow, but the upper part and the lower part of the volute are left with the umbilicus, and when the user needs to exhaust and drain the liquid, the ZG3/4 screw hole can be opened. At the work site plug screw.

         The suction and discharge flanges of the pump are vertically upward and are cast into the pump body. The flange sizes and pressure levels are equivalent to those adopted by the National Institute of standards (ANSI) standards. According to the service temperature and material category, the maximum flange pressure can reach 5MPa (about 50kgf/cm2).

In order to be reliable, the casting pump is made of cast steel shell, the hydrostatic pressure test is 7MPa (about 70kgf/cm2).

         The seal cavity (packing seal) and the pump cover are cast together, it can be packing seal and balance type, bellows or series of mechanical seal, water-cooled cavity outside the cast for the candidate's jacket, a water-cooling jacket must be equipped with special requirements or for water quality for water the temperature above 66 DEG C and hydrocarbon temperature exceeding 150 DEG C for the transmission medium. When the conveying medium needs to be insulated, low pressure steam or other heat insulating medium can be adopted in the jacket. Its hydrostatic pressure test 1MPa (about 10kgf/cm2) cooling water inlet connector ZG1/2; under the pump cover, outlet connector ZG1/2; above the pump cover.  Steam inlet joint ZG1/2 "; at the top of the cover; exit connector ZG1/2"; below the pump cover.

         Impeller as a whole casting parts, and with the rotor to do dynamic balance, it and the shaft is driven by a key, the rotor is supported at both ends. The sealing ring of the shell or the sealing ring of the impeller are all replaceable standard parts, and the good matching is ensured by the material and the different hardness. The sealing ring at both ends of the impeller design size of different sizes on the sealing ring is slightly less than the other side of the thrust bearing side of the pump, causing slight axial force, let shaft always in tension, avoid the rotor moving around.

         Pump bearing body ends are the same size, material for steel and iron two, with screws on the bracket (tile frame), and with the stop position, by coupling is arranged at the end of a radial bearing, the other end is provided with two sets of back-to-back installed thrust ball bearings, bearings with oil ring lubrication oil. Moderate amount of each bearing in vitro cast heat sink for air cooling (T less than or equal to 120 DEG C), also can use cooling fan (T=120-260 C) and cooling water (T = 260 DEG C), which is particularly suitable for dry cooling fan or poor water quality in the region.

         When the pump bearings are cooled by fans, the fan will replace the position of the dust bowl, which is unique to the pump. When the pump bearings are cooled by water, the outside of the ball bearing is cast with a water-cooled jacket.

         The bearing body with transparent plastic circular oil and oil cup, to monitor and control the oil level, both ends of the bearing body is provided with a copper dust disc, the inner hole into the bearing cover, which can prevent dust or water from entering, and can prevent oil leakage. When the bearing is broken, it can still support.

         In order to repair without crack or unloading inhalation outlet pipe is easy to break out of the impeller, bearing, seal etc.. Single stage double suction pump using a flexible diaphragm type lengthened coupling parts, and the pump shaft are tapered with split packing is very convenient.

         Pump turn: turn counterclockwise from the prime mover to the pump.
