流量6.3m3/h壓力1.0Mpa膠水專用齒輪泵用NYP320高粘度泵配XWD22KW-8-43

    高粘度泵可以輸送高粘度、高濃度無固體顆�；蚣毿≤涱w粒的潤滑性介質(zhì)；效率高，性能穩(wěn)定，使用壽命長。高粘度泵可以采用保溫夾套結(jié)構(gòu)，輸送比較高的粘度物料時可以對高粘度泵進行保溫，從而降低介質(zhì)粘度，達到更好的輸送效果，而單螺桿泵沒有保溫夾套結(jié)構(gòu)；高粘度泵在使用一段時間后，如果泵內(nèi)部間隙磨損后，不用拆泵可以自行根據(jù)高粘度泵所輸送的物料粘度來調(diào)整泵的間隙，調(diào)整后和新泵一樣可以達到良好的使用效果。高粘度泵可配安全閥，當泵或管路系統(tǒng)超壓時，安全閥門打開，形成內(nèi)部回流，保證系統(tǒng)安全。而單螺桿泵在泵本身不能設置安全閥，只能在管路中設置，提高了設備投入成本和安裝成本。選擇高粘度泵時必須考慮高粘度泵所輸送的介質(zhì)粘度，從而才能來確定高粘度泵的轉(zhuǎn)速范圍，根據(jù)高粘度泵的轉(zhuǎn)速范圍及所需工況條件下高粘度泵的正常流量范圍，才能確定高粘度泵具體型號。需要注意的是一般介質(zhì)可以這樣來選擇。 High viscosity pump can transport high viscosity, high concentration without solid particles or small soft particles lubricity medium; High efficiency, stable performance and long service life. High viscosity pump can be used in a heat preservation jacket structure, transmission is higher when the viscosity of the material can be for thermal insulation in high viscosity pump, thereby reducing medium viscosity, achieve better transmission effect, and the single screw pump heat preservation jacket structure; High viscosity pump in use after a period of time, if the pump internal clearance after wear, don't have to dismantle the pump to according to the viscosity of material delivery by high viscosity pump to adjust the clearance between the pump and adjusted, and the use of the new pump can achieve good effect. High viscosity pump can match the relief valve, when the pump and piping system overpressure, safety valve is opened, the formation of internal reflux, ensure the safety of the system. And single screw pump in the pump itself cannot set the relief valve, can only be set up in line, increase the investment of equipment cost and installation cost. Choosing high viscosity pump must consider the conveying medium viscosity, high viscosity pump order to determine the scope of the high viscosity of the pump rotation speed, according to the working condition of high viscosity of the pump speed range and required high viscosity pump under the condition of normal flow range, to determine the high viscosity pump concrete models. It's important to note that it can be to choose a normal medium.

　　其中，有些特殊化學介質(zhì)在一定溫度下會改變其化學成分，所以需要在選擇高粘度泵要特別注意泵的轉(zhuǎn)速是否適合，因為泵的轉(zhuǎn)速越高，正常工作中產(chǎn)生的熱量就越大，一旦超過介質(zhì)所限制的溫度，那么就多所輸送的介質(zhì)造成了破壞。還有些食品類介質(zhì)，比如果醬類，像我們?nèi)粘Ｖ兴�食用的果醬、花生醬、豆瓣醬等，這些介質(zhì)要求在輸送過程中必須不能夠破壞其內(nèi)部的成分進行破壞，這就要求我們所選的泵的轉(zhuǎn)速必須要低，才能保證高粘度泵在輸送過程中不破壞所輸送的介質(zhì)。高粘度泵在運轉(zhuǎn)過程中常常會出現(xiàn)卡死、抱軸轉(zhuǎn)不動的現(xiàn)象，主要原因是高粘度泵往往都是輸送的高粘度的介質(zhì)，有些是有一些雜質(zhì)的混合物理。如果泵的入口沒有安裝合適的過濾器，那么一旦大一些的硬質(zhì)顆粒進入泵腔就會把高粘度泵的內(nèi)外轉(zhuǎn)子卡死，使泵轉(zhuǎn)不動，嚴重的會把高粘度泵的內(nèi)外轉(zhuǎn)子毀掉。 Among them, some special chemical medium under a certain temperature to change its chemical composition, so need to high viscosity pump in the choice whether to pay special attention to the speed of the pump is suitable for, because the higher the pump rotation speed, the greater the heat generated by the normal work, once more than media limited by temperature, then it is more than conveying medium caused damage. Also some food medium, such as the jam class, as in our daily consumption of jam, peanut butter, broad bean paste and so on, these medium requirements must be in the process of conveying can't destroy its internal composition, this requires that we selected the speed of the pump must be low, to ensure high viscosity pump does not destroy the transmission medium in the process of delivery. High viscosity pump in the operation process often appear stuck, holding shaft fixed phenomenon, the main reason is that high viscosity pump are often transport high viscosity medium, some are some impurities mixed in physics. If the entrance of the pump is not installed the appropriate filters, so once the larger hard particle enters the pump chamber would bring high viscosity pump rotor stuck inside and outside, make the pump turns motionless, serious will destroy high viscosity pump inside and outside of the rotor.

　　所以建議大家在安裝高粘度泵的時候應該選擇合適的過濾器來安裝在泵的入口。高粘度泵抱軸的現(xiàn)象主要體現(xiàn)在不銹鋼高粘度泵的較多，因為不銹鋼材質(zhì)含碳量低，所以熱膨脹系數(shù)大，一旦泵的溫度過高，就會造成泵的內(nèi)部配件與配件之間的間隙縮小，到一定程度以后就會產(chǎn)生抱死現(xiàn)象。所以選擇不銹鋼材質(zhì)的高粘度泵是一定要注明具體的使用溫度，及介質(zhì)的潤滑性。介質(zhì)粘度的高低與高粘度泵的轉(zhuǎn)速有著密不可分的關(guān)系。如果高粘度泵輸送的介質(zhì)粘度過高，而所配的轉(zhuǎn)速也過高的話，就會造成泵的流量很低、泵的噪音很大。如果電機功率還是按常規(guī)來配的話，那么電機也會造成過載。主要是泵的轉(zhuǎn)速太高、介質(zhì)粘度又太高這樣就會造成泵阻力很大，電機的瞬間啟動電流超過額定電流，造成電機過載；由于轉(zhuǎn)速過高，使高粘度泵在運轉(zhuǎn)時內(nèi)部轉(zhuǎn)子幾乎只是形成了空轉(zhuǎn)，圍繞所輸送介質(zhì)打滑，造成吸不上料，或者是流量很小。在這種狀況下，必須降低泵的轉(zhuǎn)速，加大電機的功率，加大進出口的管徑來減少介質(zhì)的流動阻力。從而來完成介質(zhì)的輸送工作。轉(zhuǎn)速降低以后，泵的流量會反而增加，而且泵的噪音會降低，但肯定打不到理論流量。所以如果與實際工況需要流量相差太多的話，那就只能更好型號更大一點的泵。 So suggest you at the time of installation of high viscosity pump should choose the appropriate filter to installed in the entrance of the pump. The phenomenon of high viscosity pump holding shaft mainly reflects in the stainless steel of high viscosity pump is more, because of low carbon stainless steel material, so the thermal expansion coefficient is big, once the temperature of the pump is too high, can cause the interior of the pump parts and accessories the clearance between the narrow, to a certain degree after tends to lock phenomenon. So choose stainless steel high viscosity pump is must indicate the specific temperature, and medium lubricity. The discretion of the medium viscosity and high viscosity pump rotating speed of the intimate relationship. If the high viscosity pump medium viscosity is too high, and with the rotation speed is too high, will cause the pump flow rate is very low, the noise of the pump is very large. If motor power or conventional match, then the motor can cause overload. Mainly is the pump speed is too high, medium and high viscosity resistance is very big, this will cause pump motor moment of starting current more than rated current, motor overload; Due to high speed, high viscosity pump inside the rotor is barely formed when running idle, surrounding medium by sliding, cause not feeding, or flow rate is small. Under this situation, we must reduce the speed of pump, increase the power of the motor, increase the import and export of pipe diameter to reduce the flow resistance of the medium. Thus to complete medium transport work. Speed is reduced, the pump flow rate will increase instead, and the noise of the pump will be lower, but certainly can't flow theory. So if you need to flow with the actual working condition differ too much, it can only be better model bigger pump.

　　高粘度泵容易出現(xiàn)的另一個問題就是從動齒輪的銷軸容易磨損，特別是對于輸送沒有潤滑性的介質(zhì)時，銷軸磨損特別快。對此我公司改進加工工藝在原有的基礎之上通過特殊設計改進給銷軸配套加了一套注油潤滑系統(tǒng)。在高粘度泵正常運轉(zhuǎn)的情況下通過內(nèi)轉(zhuǎn)子的旋轉(zhuǎn)產(chǎn)生的離心力形成的負壓，利用注油系統(tǒng)通過特殊通道給銷軸注油，從而解決了高粘度泵銷軸磨損快的這一泵行業(yè)中存在的難題。 Another problem of the high viscosity pump is driven gear pin easy to wear and tear, especially for conveying without lubrication medium, pin shaft wear particularly fast. I improved processing technology on the basis of the original company through special design improvements to pin shaft supporting a grease lubrication system. Under the condition of the high viscosity of the normal operation of pump centrifugal force produced by the rotation of the rotor within the formation of the negative pressure, the use of injection system through the special channel to pin shaft oil, so as to solve the high viscosity pump pin shaft quick wear of the problems that exist in the pump industry.
