●輸送皂角泵并不(bú)能産生壓力，它隻是輸出流量。壓力(lì)低或無壓力，說明輸送皂角泵沒有吸入液體或洩漏嚴重。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.

　　電動機輸出功率偏小、齒 輪泵排量選得(dé)過大或壓力調得(dé)過高時，也會造(zào)成壓(yā)力不足 當然，壓力表損壞或壓力表節(jiē)流孔堵塞時也顯示不出壓力，此時可換(huàn)裝一個新的壓力表檢查。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(rú)果确認泵無流(liú)量(liàng)輸出，可能是由于泵安裝有誤、泵的轉向不對，或吸人側(進液口及吸(xī)液管道)堵塞、出口止回閥裝反或卡死了，也有可能是驅動軸斷裂了。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.

　　輸送皂(zào)角泵在轉(zhuǎn)速過低時會引起(qǐ)出液(yè)量不足，這種(zhǒng)現象往往(wǎng)是由于泵的驅動裝置打滑(huá)或功率不足所緻。此時應檢查齒 輪泵的實(shí)際轉速、泵與電動機(jī)的聯(lián)接及功率(lǜ)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.

    ●輸送皂角泵在開始運(yùn)轉(zhuǎn)前，往齒輪(lún)泵的殼體内灌滿(mǎn)待輸送的液體，便于安全(quán)啟(qǐ)動。若環境溫度低(dī)于冰點，應預先向泵内通入熱蒸汽，進行預熱處理(lǐ)，然後才可啟動齒(chǐ)輪泵。高粘度泵的旋轉方向要與進、出油口相符。齒輪泵若是第一次運行，或長期閑(xián)置(zhì)後(hòu)再使用，最(zuì)好在空(kōng)載(zǎi)或小負荷情況(kuàng)下先跑合一小時左右。如果在跑合階段預先覺察出異常溫升、洩(xiè)漏、振動(dòng)和噪聲時，應(yīng)停機檢查。高粘度齒(chǐ)輪泵的支座或法蘭與其驅動電機應采用共同的安裝基礎，基礎、法蘭(lán)或支座均需具有足夠的剛度(dù)，以減小齒輪泵運轉時産生的(de)振動和噪聲。電動機與齒輪泵須用彈性聯軸器連接，同軸度小(xiǎo)于0.1毫米，傾斜角不得大于1度。安裝聯軸器時不得用錘敲打，以免傷害齒(chǐ)輪泵的齒(chǐ)輪等零(líng)件。若用帶輪、鍊輪等驅動時應(yīng)設托(tuō)架支承，以防主動齒輪軸承受徑向力。緊固齒輪泵、電動機的地腳螺釘(dìng)時，螺釘受力應(yīng)均勻(yún)，連接可靠。用手(shǒu)轉動聯軸器時，應感覺到齒輪泵能(néng)夠輕松地轉動，沒有卡緊等異常現象出現，然後才可以配管。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.

     輸送皂角泵的吸油管道内徑應足夠大，并避免狹窄通道或急劇拐彎、減少彎頭，去除(chú)不必要的閥門、附件，盡可(kě)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(děng)元件的密封(fēng)要良好，以防止空氣(qì)侵入，從而控制氣穴與(yǔ)氣蝕的發生。止回閥(fá)與安全閥在齒輪泵(bèng)的輸出管路上最好(hǎo)安裝一個止回閥。這樣在檢(jiǎn)修泵及輸(shū)出管道時，系統中的液(yè)體不會發生(shēng)倒流。齒輪泵(bèng)帶負(fù)荷停車時，亦可防止泵倒轉而(ér)在其輸出管道内産生(shēng)局部真空。應當注意，出口止回(huí)閥不能裝反或出現卡死現象。高粘度泵(bèng)的出口(kǒu)管路上還(hái)應當設置安全閥等保護裝置(zhì)，這樣一旦泵的出口通(tōng)道發生堵塞，就可(kě)以打開安全閥卸壓。安全閥可以與泵體或泵蓋鑄成一體，也可以單獨裝配。對于需(xū)要(yào)正(zhèng)反轉的高粘(zhān)度齒輪泵，其進出口(kǒu)管路上均需設置安(ān)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.

   輸送皂角泵是輸送高粘度液(yè)體的齒輪泵，應(yīng)做到在較低的功耗、較少的洩漏、較大的壓力下輸(shū)出最多的流量。在确定所要輸送的(de)介質時，應該嚴格遵(zūn)循産品說明書上的(de)規(guī)定，盡量使用廠家推薦的流(liú)體介質，并(bìng)注意考慮系統(tǒng)的工作溫度範圍。當希望在某一較寬的溫度(dù)範圍内使用時(shí)，輸送介(jiè)質的粘度指數應該高些。輸送介質不僅是能量(liàng)傳遞的中(zhōng)介，而且也是潤滑、密封及(jí)傳熱介質。液(yè)體粘度過高會增加内(nèi)摩擦阻力(lì)，降低輸(shū)出功率，浪費能量，并産生過高的系統溫度.高粘度齒輪泵的出(chū)口管路上應當設置安全閥(fá)等保護裝置，這樣一旦泵的出口通道發生堵塞，就可以打開安全閥(fá)卸壓。對于需要(yào)正反轉的(de)高粘度齒輪泵，其進(jìn)出口管路上均需設置安全閥(fá)。High viscosity pump is conveying liquid with high viscosity gear pump, should be 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

　　輸送皂(zào)角泵額定的壓力是指泵連續工作時的(de)最高(gāo)許用壓力，而其工作壓力則決定于外部負載，安裝和調試的壽命與其工作壓(yā)力直接相關。對于不頻繁工作的齒(chǐ)輪泵，其工作壓力可取(qǔ)為泵的額定(dìng)壓力，考慮到産品質量不同(tóng)，最好将額定壓力降(jiàng)低20%～30%使(shǐ)用。對于經常工作于較高(gāo)壓力下的(de)齒輪泵，其工(gōng)作(zuò)壓力(lì)應比泵的額定壓力低1～2個壓力級。石油化工設備常常是24小時連續運轉，這時泵的工作壓力(lì)應該取得比額定壓力(lì)低得多(duō)，且工作轉速也應該低于額定轉速。如果高粘度齒輪泵的工作(zuò)壓力調整過高，則會使齒(chǐ)輪(lún)泵在超負荷下運行。High viscosity pump rated pressure refers to the maximum allowable pump continuous work pressure, and its working pressure is determined by the external load, installation and commissioning of life is directly related with work pressure.For not frequent work gear pump, the working pressure is desirable for the rated pressure of the pump, taking the quality into consideration, it is best to used pressure rated lower 20% ~ 30%.For often work under high pressure gear pump, the working pressure shall be lower than the rated pressure of the pump 1 ~ 2 pressure level.Petrochemical equipment are often 24 hours of continuous 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.
