 高粘度打膠泵用NYP110高粘度泵配XWD7.5KW-7-9減速機(jī)
高粘度齒輪泵并不能產(chǎn)生壓力，它只是輸出流量。壓力低或無壓力，說明高粘度齒 輪泵沒有吸入液體或泄漏嚴(yán)重。High viscosity gear pump
does not generate pressure, it is only the output flow.Pressure is low or no
pressure, high viscosity gear wheel pump don't inhale the liquid or leakage
is serious.
電動(dòng)機(jī)輸出功率偏小、齒 輪泵排量選得過大或壓力調(diào)得過高時(shí)，也會(huì)造成壓力不足 當(dāng)然，壓力表損壞或壓力表節(jié)流孔堵塞時(shí)也顯示不出壓力，此時(shí)可換裝一個(gè)新的壓力表檢查。Small
motor output power, gear wheel pump capacity to choose too large or pressure
too high, can cause stress Pressure gauge damage or pressure gauge orifice
jams, of course, also could not show pressure, can change a new pressure gauge
to check at this time.
如果確認(rèn)泵無流量輸出，可能是由于泵安裝有誤、泵的轉(zhuǎn)向不對，或吸人側(cè)(進(jìn)液口及吸液管道)堵塞、出口止回閥裝反或卡死了，也有可能是驅(qū)動(dòng)軸斷裂了。If
confirmed that no flow pump output, could be turned to the pumps due to pump
installation is wrong, wrong, or suction side (liquid into the mouth and suck
liquid pipeline jam, export check valve installed backwards, or card is dead,
it is possible that the drive shaft fracture.
高粘度泵在轉(zhuǎn)速過低時(shí)會(huì)引起出液量不足，這種現(xiàn)象往往是由于泵的驅(qū)動(dòng)裝置打滑或功率不足所致。此時(shí)應(yīng)檢查齒 輪泵的實(shí)際轉(zhuǎn)速、泵與電動(dòng)機(jī)的聯(lián)接及功率匹配情況等。High
viscosity pump in low speed can cause insufficient quantity of produced liquid,
this phenomenon is often due to the slippage of the pump drive or insufficient
power.Check the gear wheel pump at this time of the actual speed, pump and
motor connection and power matching, etc.
高粘度泵在開始運(yùn)轉(zhuǎn)前，往齒輪泵的殼體內(nèi)灌滿待輸送的液體，便于安全啟動(dòng)。若環(huán)境溫度低于冰點(diǎn)，應(yīng)預(yù)先向泵內(nèi)通入熱蒸汽，進(jìn)行預(yù)熱處理，然后才可啟動(dòng)齒輪泵。高粘度泵的旋轉(zhuǎn)方向要與進(jìn)、出油口相符。齒輪泵若是第一次運(yùn)行，或長期閑置后再使用，最好在空載或小負(fù)荷情況下先跑合一小時(shí)左右。如果在跑合階段預(yù)先覺察出異常溫升、泄漏、振動(dòng)和噪聲時(shí)，應(yīng)停機(jī)檢查。高粘度齒輪泵的支座或法蘭與其驅(qū)動(dòng)電機(jī)應(yīng)采用共同的安裝基礎(chǔ)，基礎(chǔ)、法蘭或支座均需具有足夠的剛度，以減小齒輪泵運(yùn)轉(zhuǎn)時(shí)產(chǎn)生的振動(dòng)和噪聲。電動(dòng)機(jī)與齒輪泵須用彈性聯(lián)軸器連接，同軸度小于0.1毫米，傾斜角不得大于1度。安裝聯(lián)軸器時(shí)不得用錘敲打，以免傷害齒輪泵的齒輪等零件。若用帶輪、鏈輪等驅(qū)動(dòng)時(shí)應(yīng)設(shè)托架支承，以防主動(dòng)齒輪軸承受徑向力。緊固齒輪泵、電動(dòng)機(jī)的地腳螺釘時(shí)，螺釘受力應(yīng)均勻，連接可靠。用手轉(zhuǎn)動(dòng)聯(lián)軸器時(shí)，應(yīng)感覺到齒輪泵能夠輕松地轉(zhuǎn)動(dòng)，沒有卡緊等異�，F(xiàn)象出現(xiàn)，然后才可以配管。High
viscosity pump before starting work, to gear pump casing filled with liquid,
facilitate safe launch.If the environment temperature is below freezing,
should advance to pump into the hot steam, preheating treatment, and then
to start the pump.The direction of rotation of the pump with high viscosity,
oil outlet in accord.Gear pump is the first run, or long-term idle before
using, had better under the condition of no load or small load to run one
hour or so.If in the running-in stage in advance detect abnormal temperature
rise, leakage, vibration and noise, should stop check.High viscosity gear
pump bearing or flange should adopt a common drive motor installationFoundation,
foundation, flange or support all needs to have enough rigidity, to reduce
the vibration of gear pump is running and noise.Motor and gear pump with
elastic shaft coupling, coaxial degree is less than 0.1 mm, Angle shall not
be greater than 1 degree.When installing coupling hammer shall not be used,
in order to avoid damage of the gear pump gearAnd other parts.If use the
belt wheel, wheel, etc, shall set bracket support, in case of driving gear
bearing by the radial force.Ground screw fastening gear pump, motor, screw
force should be uniform, reliable connection.Turn the coupling with the hand,
should feel can easily turn the gear pump, no abnormal phenomenon such as
clamping, then can be piping.
高粘度齒輪泵的吸油管道內(nèi)徑應(yīng)足夠大，并避免狹窄通道或急劇拐彎、減少彎頭，去除不必要的閥門、附件，盡可能地降低泵的安裝高度，縮短吸油管道的長度，以減少壓力損失。管接頭等元件的密封要良好，以防止空氣侵入，從而控制氣穴與氣蝕的發(fā)生。止回閥與安全閥在齒輪泵的輸出管路上最好安裝一個(gè)止回閥。這樣在檢修泵及輸出管道時(shí)，系統(tǒng)中的液體不會(huì)發(fā)生倒流。齒輪泵帶負(fù)荷停車時(shí)，亦可防止泵倒轉(zhuǎn)而在其輸出管道內(nèi)產(chǎn)生局部真空。應(yīng)當(dāng)注意，出口止回閥不能裝反或出現(xiàn)卡死現(xiàn)象。高粘度泵的出口管路上還應(yīng)當(dāng)設(shè)置安全閥等保護(hù)裝置，這樣一旦泵的出口通道發(fā)生堵塞，就可以打開安全閥卸壓。安全閥可以與泵體或泵蓋鑄成一體，也可以單獨(dú)裝配。對于需要正反轉(zhuǎn)的高粘度齒輪泵，其進(jìn)出口管路上均需設(shè)置安全閥。High
viscosity gear pump oil suction pipe diameter should be large enough, and to
avoid the narrow channel, or a sharp turn, reducing elbow, remove unnecessary
valves, fittings, as much as possible to reduce the installation height of
pump, shorten the length of the oil suction pipe, in order to reduce the pressure
loss.Components, such as pipe joint sealed well, in order to prevent the air
intrusion, thus control air-pocket and the occurrence of cavitation.Check valve
and relief valve on the output of the gear pump tube had better install a check
valve.In the overhaul pump and output pipe, the system of fluid backflow will
not occur.Gear pump to stop loading machine, can be in the output pipe to prevent
pump reverse, and create a partial vacuum.It should be noted that the outlet
check valve cannot be installed backwards or stuck.High viscosity of the pump
outlet pipe also shall set up relief valve or other protective device on the
road, so that once the clogging pump export channels, can open the relief valve
pressure relief.The relief valve can be cast and pump body and pump cover,
also can separate assembly.For high viscosity gear pump need positive &negative,
import and export all needs to set up the line safety valve.
高粘度泵是輸送高粘度液體的齒輪泵，應(yīng)做到在較低的功耗、較少的泄漏、較大的壓力下輸出最多的流量。在確定所要輸送的介質(zhì)時(shí)，應(yīng)該嚴(yán)格遵循產(chǎn)品說明書上的規(guī)定，盡量使用廠家推薦的流體介質(zhì)，并注意考慮系統(tǒng)的工作溫度范圍。當(dāng)希望在某一較寬的溫度范圍內(nèi)使用時(shí)，輸送介質(zhì)的粘度指數(shù)應(yīng)該高些。輸送介質(zhì)不僅是能量傳遞的中介，而且也是潤滑、密封及傳熱介質(zhì)。液體粘度過高會(huì)增加內(nèi)摩擦阻力，降低輸出功率，浪費(fèi)能量，并產(chǎn)生過高的系統(tǒng)溫度.高粘度齒輪泵的出口管路上應(yīng)當(dāng)設(shè)置安全閥等保護(hù)裝置，這樣一旦泵的出口通道發(fā)生堵塞，就可以打開安全閥卸壓。對于需要正反轉(zhuǎn)的高粘度齒輪泵，其進(jìn)出口管路上均需設(shè)置安全閥。High

in lower power consumption, less leakage, under the pressure of large output
the most traffic.When determining to conveying medium, we should strictly follow
the provisions of the product manuals on use manufacturers recommend fluid
as far as possible, and pay attention to consider the system operating temperature
range.When you want to use in a wide temperature range, medium viscosity index
should be higher.Medium is not only the energy transfer intermediary, but also
lubrication, sealing and heat transfer medium.Liquid viscosity is too high
will increase internal friction resistance, lower output power, waste of energy,
and generate high temperature system. High viscosity gear pump outlet pipe
shall set up relief valve or other protective device on the road, so once the
clogging pump export channels, can open the relief valve pressure relief.For
high viscosity gear pump need positive &negative, import and export all
needs to set up the line safety valve.
1、工作壓力的選定1, select the work pressure
高粘度泵額定的壓力是指泵連續(xù)工作時(shí)的最高許用壓力，而其工作壓力則決定于外部負(fù)載，安裝和調(diào)試的壽命與其工作壓力直接相關(guān)。對于不頻繁工作的齒輪泵，其工作壓力可取為泵的額定壓力，考慮到產(chǎn)品質(zhì)量不同，最好將額定壓力降低20%～30%使用。對于經(jīng)常工作于較高壓力下的齒輪泵，其工作壓力應(yīng)比泵的額定壓力低1～2個(gè)壓力級(jí)。石油化工設(shè)備常常是24小時(shí)連續(xù)運(yùn)轉(zhuǎn)，這時(shí)泵的工作壓力應(yīng)該取得比額定壓力低得多，且工作轉(zhuǎn)速也應(yīng)該低于額定轉(zhuǎn)速。如果高粘度齒輪泵的工作壓力調(diào)整過高，則會(huì)使齒輪泵在超負(fù)荷下運(yùn)行。High

operation, and at this time of the pump working pressure should be obtained
was much lower than the rated pressure, and the work speed should be lower
than the rated speed.If the high viscosity gear pump high pressure adjustment,
will make the pump running under overload.

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(xué)介質(zhì)在一定溫度下會(huì)改變其化學(xué)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?yàn)楸玫霓D(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兴秤玫墓u、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(jìn)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(yùn)轉(zhuǎn)過程中常常會(huì)出現(xiàn)卡死、抱軸轉(zhuǎn)不動(dòng)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(jìn)入泵腔就會(huì)把高粘度泵的內(nèi)外轉(zhuǎn)子卡死，使泵轉(zhuǎn)不動(dòng)，嚴(yán)重的會(huì)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(shí)候應(yīng)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?yàn)椴讳P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(huì)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(huì)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(huì)造成泵的流量很低、泵的噪音很大。如果電機(jī)功率還是按常規(guī)來配的話，那么電機(jī)也會(huì)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(huì)造成泵阻力很大，電機(jī)的瞬間啟動(dòng)電流超過額定電流，造成電機(jī)過載；由于轉(zhuǎn)速過高，使高粘度泵在運(yùn)轉(zhuǎn)時(shí)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(jī)的功率，加大進(jìn)出口的管徑來減少介質(zhì)的流動(dòng)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(huì)反而增加，而且泵的噪音會(huì)降低，但肯定打不到理論流量。所以如果與實(shí)際工況需要流量相差太多的話，那就只能更好型號(hào)更大一點(diǎn)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(gè)問題就是從動(dòng)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(shí)，銷軸磨損特別快。對此我公司改進(jìn)加工工藝在原有的基礎(chǔ)之上通過特殊設(shè)計(jì)改進(jìn)給銷軸配套加了一套注油潤滑系統(tǒng)。在高粘度泵正常運(yùn)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(fù)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.
