3GR70*3三螺桿泵在山東恒宇橡膠有限公司輸送橡膠液泵
??? 山東恒宇橡膠有限公司是一家以輪胎生產(chǎn)銷售為主,集動(dòng)力鋰電池研制生產(chǎn)、車輪生產(chǎn)、輸送帶生產(chǎn)、房地產(chǎn)開(kāi)發(fā)、國(guó)際進(jìn)出口貿(mào)易為一體的多元化經(jīng)營(yíng)的大型企業(yè)集團(tuán)。集團(tuán)始建于2005年8月,下轄7個(gè)子公司和1個(gè)辦事處,位于省級(jí)經(jīng)濟(jì)開(kāi)發(fā)區(qū)-山東廣饒大王經(jīng)濟(jì)開(kāi)發(fā)區(qū),區(qū)位優(yōu)勢(shì)明顯,交通十分便利。集團(tuán)總占地面積2400余畝,總資產(chǎn)35億元,年可生產(chǎn)各種型號(hào)的輪胎1500萬(wàn)套,實(shí)現(xiàn)產(chǎn)值60億元,出口創(chuàng)匯3億美元。企業(yè)先后被評(píng)為國(guó)家“火炬計(jì)劃”基地企業(yè)、中國(guó)橡膠輪胎出口基地企業(yè)、中國(guó)產(chǎn)學(xué)研合作創(chuàng)新獎(jiǎng)、省級(jí)“高新技術(shù)” 企業(yè)、山東省最具發(fā)展?jié)摿?00強(qiáng)、山東省“重合同守信用”企業(yè)、省四大國(guó)有銀行“AAA”級(jí)信用企業(yè)等榮譽(yù)稱號(hào)!癏eadway”品牌被評(píng)為國(guó)際知名品牌,“金途”牌輪胎和商標(biāo)分別被評(píng)為山東省名牌產(chǎn)品和山東省著名商標(biāo)。
    天然橡膠是由膠乳制造的,膠乳中所含的非橡膠成分有一部分就留在固體的天然橡膠中。一般天然橡膠中含橡膠烴92%~95%,而非橡膠烴占5%~8%。由于制法不同,產(chǎn)地不同乃至采膠季節(jié)不同,這些成分的比例可能有差異,但基本上都在范圍以內(nèi)。蛋白質(zhì)可以促進(jìn)橡膠的硫化,延緩老化。另一方面,蛋白質(zhì)有較強(qiáng)的吸水性,可引進(jìn)橡膠吸潮發(fā)霉、絕緣性下降,蛋白質(zhì)還有增加生熱性的缺點(diǎn)。 丙酮抽出物是一些高級(jí)脂肪酸及固醇類物質(zhì),其中有一些起天然防老劑和促進(jìn)劑作用,還有的能幫助粉狀配合劑在混煉過(guò)程中分散并對(duì)生膠起軟化的作用。 灰分中主要含磷酸鎂和磷酸鈣等鹽類,有很少量的銅、錳、鐵等金屬化合物,因?yàn)檫@些變價(jià)金屬離子能促進(jìn)橡膠老化,所以他們的含量應(yīng)控制。 干膠中的水分不超過(guò)1%,在加工過(guò)程中可以揮發(fā),但水分含量過(guò)多時(shí),不但會(huì)使生膠儲(chǔ)存過(guò)程中易發(fā)霉,而且還會(huì)影響橡膠的加工,如混煉時(shí)配合劑易結(jié)團(tuán);壓延、壓出過(guò)程中易產(chǎn)生氣泡,硫化過(guò)程中產(chǎn)生氣泡或呈海綿狀等。
    提取橡膠樹(shù)、橡膠草等植物的膠乳,加工后制成的具有彈性、絕緣性、不透水和空氣的材料。高彈性的高分子化合物。分為天然橡膠與合成橡膠二種。天然橡膠是從橡膠樹(shù)、橡膠草等植物中提取膠質(zhì)后加工制成;合成橡膠則由各種單體經(jīng)聚合反應(yīng)而得。橡膠制品廣泛應(yīng)用于工業(yè)或生活各方面。

● 3G 三螺桿泵工作原理 :

3G 型三螺桿泵是轉(zhuǎn)子型容積泵,適于輸送各種不含固體顆粒,無(wú)腐蝕性油類及類似油的潤(rùn)滑性液體、輸送液體粘度 2~760mm2/s ,溫度不超過(guò) 80 ℃ , 超過(guò) 80 ℃可用高溫泵 3GW 型。 3 g type is three screw pump rotor type positive displacement pump, is suitable for conveying various not containing solid particles, non-corrosive oil lubricity and similar oil liquid, conveying liquid viscosity was 2 to 760 / s, temperature not over 80 ℃ , more than 80 ℃ high temperature pump available 3 gw type.

3G 型三螺桿具有多種結(jié)構(gòu),一般小流量泵襯套和泵體合為一個(gè),可以臥式和立式安裝。進(jìn)油口方向可相隔 90 °任意安裝,軸封多數(shù)為機(jī)構(gòu)密封。中等流量以上泵,襯套為一個(gè)單獨(dú)的零件固定于泵體內(nèi),螺桿軸端裝有平衡環(huán)以液力平衡其軸向力。一般結(jié)構(gòu)為臥式。進(jìn)油口方向亦可以相隔 90 °任意安裝。改變泵體后可制成立式。軸封根據(jù)情況有機(jī)械密封和軟填料密封兩種結(jié)構(gòu)。 Three screw with multiple structure of 3 g, general small flow pump bushings and pump body into one, can be installed in a horizontal and vertical.Oil inlet direction can be 90 ° apart any installation, most of the shaft sealing seal for your organization.The medium flow in pump, bushing as a separate component fixed in the pump body, screw shaft end is equipped with the gimbal ring to hydraulic balance the axial force.The general structure is horizontal.Inlet direction also can be 90 ° apart any installation.After the change of pump body can be made into vertical.Depending on the situation of the shaft sealing with mechanical seal and soft packing seal two structures.

3G 型三螺桿泵軸伸支承較小,應(yīng)由原動(dòng)機(jī)經(jīng)彈性聯(lián)軸器直接驅(qū)動(dòng),不得用皮帶輪等會(huì)產(chǎn)生額外徑向力較大的傳動(dòng)方式傳動(dòng)。 3 g type three-screw pump shaft and bearing is small, should be driven by a prime mover directly by the elastic coupling, shall not be used pulley will produce additional radial force large transmission way.

● 3G 三螺桿泵輸送各種油類時(shí)應(yīng)注意事項(xiàng): When conveying various oil matters should be paid attention to:

1 、輸送 40~150mm2/s 的油類最合適,允許按泵的最高工作壓力使用。 2 、輸送 40mm2/s 以下的油類,為保證泵的流量及壽命應(yīng)降壓使用。 3 、輸送 150mm2/s 以上的油類,且進(jìn)油管道過(guò)長(zhǎng),彎頭過(guò)多,泵工作時(shí)如產(chǎn)生噪音或振動(dòng)現(xiàn)象,則應(yīng)考慮更換低一級(jí)轉(zhuǎn)速的電機(jī)運(yùn)轉(zhuǎn)或縮短吸入管道,減少?gòu)濐^。 1, delivery was 40 ~ 150 / s best oils, permitted to use according to the maximum working pressure of pump.2, transmission oil, under 40 was/s in order to ensure the pump flow and life should be used antihypertensive.3, transmission of more than 150 was/s oils, and the oil inlet pipe is too long, too much bend, such as noise or vibration phenomenon when the pump work, should consider to replace the low level of rotational speed of motor operation or shorten the suction pipe, reducing elbow.

● 3G 型三螺桿泵安裝要求 :3 g type three-screw pump installation requirements:

1 、安裝前應(yīng)檢查泵的油封是否良好,并檢查泵在運(yùn)輸中是否損壞,可用手轉(zhuǎn)動(dòng)聯(lián)軸器是否有卡勁現(xiàn)象,如有則應(yīng)拆泵進(jìn)行清洗,修理和校正。 1, before installation should check whether the oil seal of the pump is good, and check the pump is damaged in transportation, turn the coupling usable hand card trouble phenomenon, if there is any should tear open pump for cleaning, repair and calibration.2 、安裝泵的進(jìn)油和排油管道時(shí),其管徑不得小于泵的進(jìn)油和出油口口徑,進(jìn)油管道不得過(guò)長(zhǎng),彎頭不得過(guò)多,否則將影響泵的工作狀態(tài)。 2, installation of pump suction and discharge of oil pipe, the pipe diameter shall not be less than the oil inlet of the pump and the oil outlet diameter, inlet pipe shall not be too long, elbow shall not too much, otherwise will affect the pump working condition.3 、當(dāng)有兩臺(tái)以上的泵安裝在同一條主管線上,為便于泵的啟動(dòng),在近泵的排油管上必須安裝逆止閥。 3, when more than two head of pump installed in the same line, to facilitate pump start-up, in close to the oil drain pump must be installed on a non-return valve.4 、對(duì)于在較高溫度(指 60 ℃以上)下輸送粘度大的油類(如:重油)的備用泵,必須是熱備用泵,否則泵在低溫下啟動(dòng)會(huì)造成電機(jī)過(guò)載或泵損壞。(建議在靠近泵的排油管上的逆止閥旁,并聯(lián)安裝一個(gè)小回流閥,對(duì)備用泵可微啟回流閥,使泵緩慢逆轉(zhuǎn),其逆轉(zhuǎn)速≤ 100 轉(zhuǎn) / 分,使部分熱油經(jīng)常流過(guò)泵內(nèi),達(dá)到泵熱備用目的)。 4, for under high temperature (above 60 ℃ ) conveying the viscosity of oil (such as: heavy oil) of the standby pump, it must be hot standby pump, otherwise the pump at low temperature can cause the damage of motor overload or pump.(suggest near the exhaust non-return valve on the tubing pump, a small return valve installed in parallel, differentiable and the backflow preventer to standby pump, the pump slow reversal, the reverse speed 100 r/min or less, often make some hot oil flows through the pump, to pump hot standby purposes).5 、輸送介質(zhì)內(nèi)含有機(jī)械雜質(zhì)。將嚴(yán)重影響泵的運(yùn)轉(zhuǎn)和降低使用壽命,因此在泵安裝前,必須仔細(xì)清除進(jìn)油管內(nèi)的焊渣,沙粒等雜質(zhì),并應(yīng)在進(jìn)油管道靠近泵處安裝濾器,濾器網(wǎng)孔大小,可根據(jù)工作情況及介質(zhì)粘度確定。(一般可用 40~80 目網(wǎng)),過(guò)濾面積一般不得小于進(jìn)油管橫截面積的 20 倍。 5, mechanical impurity is contained within the transmission medium.Will seriously affect the operation and reduce the service life of pump, so before the pump installation, must be carefully clean up the feed tube welding slag, impurities such as grains of sand, and shall be installed in the inlet pipe near the pump filter, filter mesh size, is decided according to the working condition and medium viscosity.Available (40 ~ 80 mesh net), filter area generally shall not be less than 20 times into the cross-sectional area of the tubing 6 、盡量在泵進(jìn)油和排油口處的螺紋孔上連接壓力表和真空表,以便于觀察泵的運(yùn)轉(zhuǎn)狀態(tài)。 6, as far as possible in the pump suction and discharge of oil on the threaded hole mouth connect pressure gauge and vacuum gauge, in order to observe the pump running state.7 、原動(dòng)機(jī)與泵的轉(zhuǎn)軸必須在同一中心線上,可用直尺測(cè)隙規(guī)在聯(lián)軸器圓周上間隔 90 °處檢查。 8 、原動(dòng)機(jī)與泵的轉(zhuǎn)向必須一致,嚴(yán)格禁止原動(dòng)機(jī)驅(qū)動(dòng)泵逆轉(zhuǎn)。電機(jī)接線時(shí),應(yīng)先脫開(kāi)電機(jī)與泵的聯(lián)軸器,對(duì)電機(jī)作試運(yùn)轉(zhuǎn)。使其轉(zhuǎn)向與泵的轉(zhuǎn)向標(biāo)志一致。 7, prime mover and the pump shaft must be in the same center line, available ruler feeler gauge in the coupling of the circumference of a circle by 90 ° in check.8, steering engine and pump must be consistent, strictly prohibited prime motor driven pump reversal.Electrical wiring, should first release coupling of motor and pump, a test run on the motor.The steering pump and steering sign agreement.
