加藥泵常用的加藥罐種類與介紹
什么是滾塑塑料加藥罐（儲罐、加藥罐）？AliWater滾塑塑料加藥罐（儲罐、加藥罐）是由純聚乙烯或改性塑料（同一塑料的不同牌號的混合物）、金屬材料、滾塑塑料工藝（或滾塑塑料工藝、空氣成型技術(shù)）制成的，通過重力和三維運動在模具上進行涂塑，然后在鋼罐內(nèi)嵌入網(wǎng)狀結(jié)構(gòu)，使鋼襯塑料復合罐冷卻脫模。滾塑塑料加藥罐（儲罐和加藥罐）的性能完全取決于高質(zhì)量的防腐材料。聚乙烯（線性低密度聚乙烯）常用作滾塑塑料加藥罐（儲罐和加藥罐）的防腐材料。滾塑聚乙烯加藥罐的具體特性是線性低密度聚乙烯的特性與滾塑工藝整體成型的特性之和（即加藥罐的優(yōu)良防腐性能和加藥罐的整體完整性，無任何焊接）。
滾塑塑料加藥罐特點（儲罐、加藥罐）
① 滾塑塑料加藥罐（儲罐、加藥罐）耐溶劑、抗氧化。滾塑塑料加藥罐（儲罐、加藥罐）耐大多數(shù)化學品，特別是無機和有機強酸、堿、鹽和大多數(shù)有機溶劑。聚乙烯不耐幾種有機溶劑，如丙酮、氯仿、苯、甲苯、乙酸乙酯等溶劑。它不耐少量氧化或還原物質(zhì)，增強性強，但在一定厚度下仍能使用（外表面形成保護層）。另外，由于聚乙烯優(yōu)異的抗氧化性，能抵抗弱氧化溶劑和罐壁的光氧化，使罐不易脆化，使用壽命長。
② AliWater滾塑塑料加藥罐（儲罐、加藥罐）的耐溫性全塑料聚乙烯加藥罐（儲罐、加藥罐）的耐溫性完全取決于聚乙烯（線性低密度聚乙烯），根據(jù)經(jīng)驗，小體積可承受70℃以下的溫度，大體積可承受60℃以下的溫度，鋼襯塑料可承受90℃以下的溫度，縫隙可承受100℃的溫度。聚乙烯塑料加藥罐的低溫性能非常好，能承受-30℃的低溫。另外，聚乙烯是傳熱不良的導體，所以全塑料聚乙烯加藥罐（儲罐、加藥罐）具有良好的保溫性能，所以不能采用夾套式加熱或冷卻裝置。如果需要加熱或冷卻裝置，可以使用盤管式裝置。
③ 滾塑塑料加藥罐（儲罐和加藥罐）的剛性強度、溶液比重和使用壓力全塑料聚乙烯加藥罐由于其厚壁、穹頂、圓形和橢圓形的垂直水平結(jié)構(gòu)和罐體外加強結(jié)構(gòu)，具有一定的剛性強度。一般情況下，垂直頂比水平頂具有更高的剛性強度，水平頂比垂直頂具有更大的比重，藥物的比重可以大于大體積藥物的比重。全塑料聚乙烯加藥罐（儲罐、加藥罐）一般只作為常壓容器使用，不耐真空和壓力。鋼襯聚乙烯加藥罐（儲罐、加藥罐）為鋼殼，內(nèi)裝整體塑料，內(nèi)嵌鋼網(wǎng)結(jié)構(gòu)。鋼塑聚乙烯加藥罐的剛性強度高于聚乙烯全塑加藥罐。強度來自外部鋼和內(nèi)部塑料。它是一種軟硬結(jié)合的復合剛性強度材料。強度還取決于鋼殼的厚度、塑料襯里的厚度和加藥罐的形狀。如果外罐是壓力容器，即鋼塑聚乙烯加藥罐也可以是壓力容器，但較厚的鋼罐仍能承受一定的液壓（2-4kg/cm2）和較小的容積，以及一定的真空（<0.8kg/cm2）。
④ 滾塑塑料加藥罐（儲罐、加藥罐）防腐層的完整性，體現(xiàn)了聚乙烯全塑加藥罐防腐層與鋼塑復合罐防腐層一體成型，無任何缺陷，滾塑塑料加藥罐無滲漏，使用壽命長的特點塑料焊縫（塑料焊縫是塑料加藥罐的薄弱環(huán)節(jié)）。目前，鈦龍加藥泵、VAREM加藥泵、ZILMET加藥泵、WATERSUNNY加藥泵等組成的加藥裝置配套的加藥箱(罐)常規(guī)均為AliWater滾塑加藥箱、加藥罐，材質(zhì)常規(guī)為PE材質(zhì)，也可定制PP、PVC、不銹鋼304、不銹鋼316或者玻璃鋼材質(zhì)。
⑤ 滾塑塑料加藥罐（儲罐、加藥罐）規(guī)格型號滾塑塑料全塑聚乙烯加藥罐可分為立式、臥式和異型加藥罐，均為模具產(chǎn)品。公司設(shè)計了相對固定的標準產(chǎn)品。標準品種主要考慮普通容積（1-50m3），AliWater加藥罐的尺寸及安裝使用的方便美觀，立式（平底拱頂、平底平蓋）、臥式（圓形橢圓形）、異形罐（錐形底）為最佳。此外，還應(yīng)考慮到交通的便利性。全塑聚乙烯加藥罐的設(shè)計厚度為保證剛性強度的經(jīng)濟厚度。鋼襯塑料加藥罐為非標產(chǎn)品，可設(shè)計成各種形式的加藥罐（1-150m3）供用戶使用。但由于滾塑設(shè)備、工藝和運輸條件的限制，加藥罐的設(shè)計也受到限制。較大直徑不大于4.5m，較大長度不大于13m，較大設(shè)計容積小于150m3時，徑高比不宜過大（小于0.8）。
⑥ 滾塑塑料加藥罐（儲罐、加藥罐）符合衛(wèi)生標準。由于聚乙烯是無毒材料，成型加藥罐內(nèi)壁光滑，在低溫條件下可替代符合食品衛(wèi)生標準的不銹鋼容器，其耐酸堿性比不銹鋼材料強得多。可用于盛放各種食品、飲料、酒、醋等。
⑦ 鋼襯塑料汽車加藥罐是鋼塑復合加藥罐的延伸產(chǎn)品，是目前較為理想的防腐汽車加藥罐。罐體設(shè)計為水平橢圓、圓形和方形圓形儲罐結(jié)構(gòu)，采用鋼梁框架支撐，并設(shè)有防浪板（內(nèi)焊塑料板）、組合式人孔、柵欄槽、排污口等專用裝置。
⑧ 塑鋼襯塑混合罐是鋼塑復合加藥罐的延伸產(chǎn)品。是一種用于特強酸性物質(zhì)的反應(yīng)設(shè)備。它能承受90℃以下的溫度。盤管可用于加熱或冷卻。形狀可為平底平蓋、拱底拱蓋、平底拱底、平底錐底等，并可配減速器和防腐攪拌漿。
⑨ AliWater滾塑塑料加藥罐（儲罐、加藥罐）的其他特點是內(nèi)外均采用塑料防腐，重量輕，安裝方便。鋼襯塑料加藥罐內(nèi)壁防腐，外部需刷防腐漆，安裝方便。
Types and introduction of dosing tank commonly used in dosing pump
What is rotational plastic dosing tank (tank, dosing tank)? Aliwater rotational plastic dosing tank (storage tank, dosing tank) is made of pure polyethylene or modified plastic (mixture of different brands of the same plastic), metal materials, rotational plastic process (or rotational plastic process, air molding technology). It is coated on the mold by gravity and three-dimensional movement, and then embedded in the steel tank network structure to make the steel lined plastic composite tank cold But it's not. The performance of rotational plastic dosing tank (storage tank and dosing tank) completely depends on high-quality anti-corrosion materials. Polyethylene (linear low density polyethylene) is often used as anti-corrosion material of rotational plastic dosing tank (storage tank and dosing tank). The specific characteristics of rotational molding polyethylene dosing tank are the sum of the characteristics of linear low density polyethylene and integral molding of rotational molding process (i.e. excellent anti-corrosion performance of dosing tank and integral integrity of dosing tank without any welding).
Characteristics of rotational plastic dosing tank (tank, dosing tank)
① Rotational plastic dosing tank (storage tank, dosing tank) is solvent resistant and antioxidant. Rotational plastic dosing tanks (tanks, dosing tanks) are resistant to most chemicals, especially inorganic and organic strong acids, bases, salts and most organic solvents. Polyethylene is not resistant to several organic solvents, such as acetone, chloroform, benzene, toluene, ethyl acetate and so on. It is not resistant to a small amount of oxidation or reduction substances and has strong reinforcement, but it can still be used under a certain thickness (the outer surface forms a protective layer). In addition, due to the excellent oxidation resistance of polyethylene, it can resist weak oxidation solvent and photooxidation of tank wall, so that the tank is not easy to embrittle and has a long service life.
②  The temperature resistance of aliwater rotational plastic dosing tank (storage tank, dosing tank) the temperature resistance of all plastic polyethylene dosing tank (storage tank, dosing tank) completely depends on polyethylene (linear low density polyethylene). According to experience, small volume can withstand the temperature below 70 ℃, large volume can withstand the temperature below 60 ℃, steel lined plastic can withstand the temperature below 90 ℃, and gap can withstand 100 ℃ The temperature of the temperature. The low temperature performance of polyethylene plastic dosing tank is very good, which can withstand the low temperature of - 30 ℃. In addition, polyethylene is a poor heat transfer conductor, so all plastic polyethylene dosing tank (storage tank, dosing tank) has good thermal insulation performance, so jacket heating or cooling device cannot be used. If heating or cooling devices are required, coil type devices can be used.
③ Rigid strength, solution specific gravity and service pressure of rotational plastic dosing tank (storage tank and dosing tank) all plastic polyethylene dosing tank has certain rigid strength due to its thick wall, dome, round and oval vertical horizontal structure and tank external strengthening structure. In general, the vertical top has higher rigid strength than the horizontal top, and the horizontal top has larger specific gravity than the vertical top. The specific gravity of drugs can be greater than that of large volume drugs. All plastic polyethylene dosing tank (storage tank, dosing tank) is generally only used as atmospheric pressure container, not resistant to vacuum and pressure. The steel lined polyethylene dosing tank (storage tank, dosing tank) is a steel shell with integral plastic and steel mesh structure. The rigid strength of steel plastic polyethylene dosing tank is higher than that of polyethylene all plastic dosing tank. The strength comes from the outer steel and the inner plastic. It is a kind of composite rigid strength material with soft and hard combination. The strength also depends on the thickness of the steel shell, the thickness of the plastic lining and the shape of the dosing tank. If the outer tank is a pressure vessel, the steel plastic polyethylene dosing tank can also be a pressure vessel, but the thicker steel tank can still bear certain hydraulic pressure (2-4kg / cm2), small volume and certain vacuum (< 0.8kg / cm2).
④ The integrity of the anti-corrosion coating of rotational plastic dosing tank (storage tank and dosing tank) reflects the characteristics of polyethylene all plastic dosing tank anti-corrosion coating and steel plastic composite tank anti-corrosion coating, no defects, no leakage and long service life of rotational plastic dosing tank. Plastic welding seam (plastic welding seam is the weak link of plastic dosing tank). At present, the dosing boxes and tanks of Titan dosing pump, varem dosing pump, zilmet dosing pump and watersunny dosing pump are all made of aliwater rotational plastic dosing boxes and tanks, and the materials are usually made of PE, or PP, PVC, stainless steel 304, stainless steel 316 or glass steel.
⑤ Rotational plastic dosing tank (storage tank, dosing tank) specification and model rotational plastic all plastic polyethylene dosing tank can be divided into vertical, horizontal and special-shaped dosing tank, all of which are mold products. The company has designed relatively fixed standard products. The standard varieties mainly consider the ordinary volume (1-50m3), the size of aliwater dosing tank and the convenience and beauty of installation and use, and the vertical type (flat bottom vault, flat bottom flat cover), horizontal type (circular oval) and special-shaped tank (conical bottom) are the best. In addition, the convenience of transportation should also be considered. The design thickness of all plastic polyethylene dosing tank is the economic thickness to ensure the rigid strength. Steel lined plastic dosing tank is a non-standard product, which can be designed into various forms of dosing tank (1-150m3) for users. However, due to the limitation of rotational molding equipment, process and transportation conditions, the design of dosing tank is also limited. When the larger diameter is not more than 4.5m, the larger length is not more than 13m, and the larger design volume is less than 150m3, the diameter height ratio should not be too large (less than 0.8).
⑥ Rotational plastic dosing tank (storage tank, dosing tank) meets the health standard. Because polyethylene is a non-toxic material, the inner wall of the shaped dosing tank is smooth, and it can replace the stainless steel container that meets the food hygiene standard at low temperature. Its acid-base resistance is much stronger than that of stainless steel. It can be used to hold all kinds of food, drink, wine, vinegar, etc.
⑦ Steel lined plastic automobile dosing tank is an extension product of steel plastic compound dosing tank, which is an ideal anti-corrosion automobile dosing tank at present. The tank body is designed as horizontal ellipse, circular and square circular tank structure, supported by steel beam frame, and equipped with anti wave plate (internally welded plastic plate), combined manhole, fence slot, sewage outlet and other special devices.
⑧ Plastic steel lined mixing tank is an extension of steel plastic compound dosing tank. It is a kind of reaction equipment for strong acid substances. It can withstand temperatures below 90 ℃. Coils can be used for heating or cooling. The shape can be flat bottomed flat cover, arch bottomed arch cover, flat bottomed arch bottom, flat bottomed cone bottom, etc., and can be equipped with reducer and anti-corrosion mixing slurry.
⑨ The other characteristics of aliwater rotational plastic dosing tank (storage tank, dosing tank) are that both inside and outside are made of plastic for anti-corrosion, light weight and easy installation. The inner wall of the steel lined plastic dosing tank is anticorrosive, and the outer part needs to be painted with anticorrosive paint, so it is easy to install.
