จำหน่ายเกจวัดแรงดัน Pressure Gauge ทุกยี่ห้อ


digital pressure gauge of Dutch company DSM Nutritional Products AG makes use of the spray drying method when producing vitamin and carotenoid powders for the pharmaceutical and meals industries. The procedure uses pump know-how to convey various emulsions into a spray tower, the place they are dried into powder. But the feed and booster pump that was being used proved to be an uncertainty factor because the diaphragm required for the pumping process tended to tear when the pump was began up. Generally, such production interruptions may be corrected by way of quick maintenance and repair work.
However, it is very costly to switch a diaphragm or a whole system. DSM was looking for another and finally made a find after they talked to the pump experts at Lewa Nikkiso Switzerland, who really helpful a Lewa triplex course of diaphragm pump for the spray tower utility. The drive unit features a safe start-up mode that keeps the diaphragm situated within the impartial position, and continuous regulation utilizing an integrated monitoring system. Since the hermetically tight pumps are electropolished and CIP-approved, it’s easy to satisfy the meals industry’s stringent hygienic provisions.

“Pump expertise performs a central role in drying oil-in-water emulsions for the meals and pharmaceutical industries. These emulsions comprise substances corresponding to vitamins, carotenoids, or polyunsaturated fatty acids as active elements,” explains Natalie Ibald, plant supervisor of formulations at DSM Nutritional Products AG. “As part of the process chain, every pump is 100% built-in into the closed plant system. The pumps are used for conveying the mixtures into the spray tower.”

With the previous system, the chance of unforeseen interruptions to this process couldn’t be ruled out. As a outcome, the completely different emulsions couldn’t be processed further. In other phrases, it was not attainable to dry them into powder. The pump diaphragm was the rationale: it was usually too delicate to resist the stress positioned on it when starting up the pump and would rupture. Replacing the diaphragm lowered the system’s service life and typically meant that trouble-free operation couldn’t be assured.

In the course of trying to find a dependable different, DSM got in touch with the Swiss subsidiary of pump manufacturer Lewa.
“We were already conversant in Lewa Nikkiso Switzerland as a supplier of sturdy methods with lengthy service lives in the SFP sector. To ensure trouble-free spray drying, we thought it might be good to hitch forces with the specialists from Lewa and come up with a design to resolve the technical issues,” says Ibald.
DSM is dedicated to continually enhancing its processes and investing in know-how. This dedication, along with prior experience with the short service lives of the earlier pumps, led DSM to position particular give consideration to reliable function and a sturdy design through the venture planning phase. The listing of necessities also included a considerable variety of stringent hygienic provisions that had to be fulfilled.
“Certain foods have provisions concerning microbiological purity that are many occasions more stringent than these for producing other food merchandise,” explains Ibald. “This meant that the new feed and booster pump needed to meet these tougher situations and each kind of contamination had to be ruled out to provide the widest potential number of products on the system.”

After a visit on the company premises to suppose about the spatial and technical parameters, Lewa Nikkiso Switzerland beneficial a sort G3F triplex process diaphragm pump for the spray tower software. This pump contains a fully secure start-up operation, since a spring constantly holds the built-in sandwich diaphragm situated in a impartial position.
This protects the diaphragm towards incorrect positioning and prevents it from being damaged while the pump is beginning up, increasing system availability substantially. And the Lewa triplex is managed utilizing a stress aid valve that is installed within the hydraulic part and may be configured for the precise state of affairs. Therefore, the pump may be tailored to totally different operational situations to be able to forestall any overloads which will come up. This ensures that the unit has an extended service life and smooth regular operation for the complete system.

In addition to the pressure aid valve and the spring management, the design of the diaphragm additionally performs an important role in guaranteeing dependable pump operation. The patented sandwich diaphragm consists of two separate PTFE diaphragms which are extraordinarily long-lasting. เพรสเชอร์เกจ are related to each other through positive interlocking in the course of the discharge stroke and mechanical force-fitting during the suction stroke.
This makes the pump hermetically tight and effectively prevents exterior contamination. As an additional safety feature, the DPS monitoring system from Lewa constantly monitors the situation of the diaphragm. The monitoring unit promptly shows any injury to the system that leads to increased stress in the diaphragm area.
This makes it possible to hold out preventive upkeep and repair work earlier than the diaphragm even begins to rupture and potentially contaminates the pumped fluid. Thus, it is often pointless to change the pump off instantly, which implies that neither the pumping process nor spray drying are negatively impacted to a significant extent. If harm to a diaphragm is detected, production can continue without any problems up to a deliberate maintenance cease. The components can then be replaced quickly and easily by releasing the cassette for the assembly.

The hermetically tight design of the method diaphragm pump does extra than just ensure dependable steady operation. It can also be a central component for fulfilling the stringent hygiene provisions that the spray tower utility is subject to. The Lewa triplex maintains a hermetically tight area with out dynamic seals, guaranteeing utterly clear and aseptic production conditions. All pump heads that come into contact with the product are additionally electropolished, which makes it potential to ensure FDA-compliant pump operation.
Because the pump can be cleaned in place (CIP) using completely different alkaline and acidic agents and without prior dismantling, it’s possible to meet the special requirements for baby food as properly. The provisions for baby food are 1,000 occasions extra stringent than those for other merchandise within the meals sector. Thanks to the hermetically tight design, electropolishing, and CIP cleaning, we have been capable of rule out any contamination of the pumped medium and clearly meet the required hygiene normal.

The first quote was acquired in June of 2018 and in September of the identical year, DSM Nutritional Products AG positioned an order for the triplex course of diaphragm pump. In operation since April 2019, the pump has turn out to be an indispensable part of manufacturing on the plant in Sisseln.
“In every part of the venture, Lewa Nikkiso Switzerland demonstrated fast response instances and well-founded expertise, which made a key contribution to implementing the project successfully,” says Ibald. “Our specifications with regard to high quality, robustness, and hygiene had been followed to the letter in this project. As a result, our manufacturing has turn into noticeably more efficient and reliable.”
