矽(xī)酮膠是一種類似軟膏，一(yī)旦接觸空氣中的(de)水分就會固(gù)化成一種堅韌的橡膠類固體的材料。主要分為脫醋酸型，脫醇型，脫氨型，脫丙型(xíng)。矽酮膠因為常被用于玻璃方面的粘接和密封(fēng)，所以俗稱玻璃膠。Silicone rubber is a kind of ointment, once contact with moisture in the air will be solidified into a tough rubber type of solid materials.Mainly divided into the type of acetic acid, glycol type, ammonia, c.Because silicone rubber is often used for bonding and sealing glass, so commonly known as glass glue.
    單組份矽酮玻璃膠是一種類似軟膏，一(yī)旦接觸空氣中的水分就會固化成一種堅韌的橡膠類固體的材料。One-component silicone glass glue is a kind of ointment, once contact with moisture in the air will be solidified into a tough rubber type of solid materials.
    矽酮玻璃膠的粘接力強，拉伸強度大，同時又具有耐候性、抗振性，和防潮、抗臭氣和适(shì)應冷熱變化大的特點。加之其較廣(guǎng)泛的适用性，能實現大多數建材産品之間的粘合，因此應用價值非常大。Silicone glass glue stick relay is strong, tensile strength, and vibration resistance, weather and moisture, odor resistant and adapt to the characteristics of the change of hot and cold.Together with its broad applicability, which can achieve most adhesion between building materials products, so the application value is very big.
    矽酮(tóng)膠英文名字是SILICONE，是有機矽部分産品. 主要分為(wéi)脫醋酸型，脫醇型，脫氨(ān)型(xíng)，脫丙型。玻璃膠是矽(xī)酮(tóng)膠俗稱名稱，因為用戶購買矽酮密封膠主要使用于玻(bō)璃(lí)方面的粘接和密封(fēng)，所以就叫做玻璃膠。Are English name is SILICONE, SILICONE rubber SILICONE products. Mainly divided into acetic acid type, type to take off the alcohol, ammonia, c.Glass rubber is a silicone rubber, commonly known as the name for the user to buy silicone sealant is mainly used in glass bonding and sealing, so he called the glass glue.
    化學成分有聚二甲基矽氧烷，二氧(yǎng)化矽(xī)的聚合物都可以稱矽酮。Chemical composition of polydimethylsiloxane, silicone polymer silica can say.
    矽酮的主要成分是聚二甲基矽氧(yǎng)烷，二氧化矽等組成。矽酮結構中矽和氧構成雙鍵的碳被矽代替。The main components of the silicone is polydimethylsiloxane, silica, etc.Silicone structure of silicon and oxygen by silicon instead of carbon double bond.
    就是(shì)這樣一個結構式，兩個矽酮可以發生聚合，斷掉一(yī)個矽氧鍵(jiàn)，Si原子再接一個基團，兩個氧連(lián)起(qǐ)來，就生成矽酮類物質。Is a structured, twosilicone can occur polymerization, breaking a silica key, Si atoms by another group, the two together, oxygen generates silicone material.

   高粘度齒輪泵的吸(xī)油管道内徑(jìng)應足夠大，并避免狹窄通道或急劇(jù)拐彎、減少彎頭，去除不必要的閥門、附件，盡(jìn)可能(néng)地降低泵的安裝高度，縮短吸油管道的長(zhǎng)度，以減少壓力損失。管接頭等元(yuán)件的密封要良好(hǎo)，以防止空氣侵入，從而控制氣穴與(yǔ)氣蝕的發生。止回閥與安全閥在齒輪泵的輸出管(guǎn)路(lù)上最好安裝一(yī)個止回閥。這樣在檢修泵及輸出管道時，系統中的(de)液體不會發生倒流。齒輪泵帶(dài)負荷停車(chē)時，亦可防止泵倒轉而在其輸出管道内産生局部真(zhēn)空。應當注意，出口(kǒu)止(zhǐ)回閥不能裝反或出現卡死現象。高粘度泵的出口管路上還應當設置安全閥等保護裝(zhuāng)置(zhì)，這樣一旦泵的出口通道發生堵塞，就可以打開(kāi)安全閥卸(xiè)壓。安全(quán)閥可以與泵體或(huò)泵蓋鑄成一體(tǐ)，也可以單獨裝配。對于需(xū)要正反轉的高粘度齒輪泵，其進出口管路上均需設置(zhì)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(gāo)粘度泵是輸送高粘度液體的齒輪(lún)泵，應(yīng)做到在較低的功耗(hào)、較少的洩(xiè)漏、較大的(de)壓力下輸出最多的流量(liàng)。在确定所要輸送的介質時，應該嚴格遵循産品說明書上的規定，盡量使用廠家推薦的流體介質，并注意(yì)考慮系(xì)統的工作溫度範圍。當(dāng)希望(wàng)在某一較寬的溫度範圍内使用時，輸送介質的粘度指(zhǐ)數應該高些。輸(shū)送介質不僅是能量(liàng)傳遞的中介，而(ér)且也是潤滑、密封及(jí)傳熱介質。液體粘度過高會增加内摩擦阻力，降低(dī)輸出功率，浪費能量，并産生過高的系統溫度.高粘度齒輪泵的出口管(guǎn)路上應當設置安全(quán)閥等保護(hù)裝置，這樣一(yī)旦泵的出口通道發生堵塞，就可以打開安全閥卸壓。對于需要(yào)正反轉的高粘度(dù)齒輪泵，其進出口管路(lù)上均需設置安全閥。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.
