Description
Technical field
The utility model relates to a kind of pharmacy corporation water for injection system, relates in particular to a kind of pharmacy corporation water for injection control system of invariable pressure.
Background technology
The water for injection system that pharmacy corporation uses, according to the related request of GMP, the water for injection that whole system is carried is in mobile state all the time, to prevent growing of microorganism.For this reason, the water for injection system all adopts the closed mode of annular on circuit design, by the pressurized delivered of circulating water pump, as motive force, each U-shaped threeway with water spot is connected one by one, thereby reach the phenomenon that does not have blind spot and stagnant water.In addition because the characteristic of water for injection, system must keep uninterrupted circulation in 24 hours in disinfection cycle, in case main cause is water in pipeline, stop to flow then have a microbial growth may, on the other hand, in the quantity-produced process, in case water for injection can not regular supply, then produce and to interrupt, pharmaceutical raw material in the workshop just has risk rotten or the generation microorganism, and product quality is on the hazard.And in this course, can produce what directly threaten to the continuous circulation of water for injection is exactly the failure problems of circulating water pump, in case water pump breaks down and namely will change again and need sterilize again, it is longer to expend time in, and production risk is bigger.Therefore we arrange two water pumps in pipeline is carried in the system of majority, and the using and the reserved have influence on production thereby anti-locking system interrupts conveying because of the water pump failure problems.We all can run into two problems but in the arranging of system.
The first, in order to guarantee water for injection system 24 hours circulation, water for injection rely on that the motive force of pump adopts that annular closed cycle is transported to the workshop each use water spot.Because all make the resistance of system increase greatly with water spot for fear of the U-shaped threeway series connection that blind spot or stagnant water all adopt, such connection may make some use and select when a large amount of water and cause other situations with the water spot water shortage to occur that terminal ducted water velocity is therefore reduction also.If so and the flow of single increase water pump remedies the too fast problem appearance of water velocity that can cause when not using.Because require the flow velocity of water for injection should be in 0.915 meter per second the international pharmaceutical engineering Shi Xiehui of ISPE, speed be low excessively, and the danger of bacteria breed is arranged; Speed is too high, the tube wall Rouge(famille rose of can growing).Therefore in the problem that should consider that flow rate of water flow is constant in service of water for injection.
The second, water for injection system water pump adopts the setting of the using and the reserved, and such arranging can effectively guarantee the uninterrupted of the circulating system.But under the simultaneously online situation of two water pumps, if the 1# water pump is opened, the 2# water pump is not opened, before and after the water pump under the situation of valve closing.Front and back one segment distance of 2# water pump will produce the slough, and the danger of growing microorganism is arranged.If the 1# water pump breaks down, drop into the 2# water pump immediately and use, then the water of whole system will be contaminated, and the quality of product will can not get guaranteeing; If the 1# water pump is opened, under the situation that the 2# water pump is also opened, can prevent the problem of water pump location stagnant water.But two water pumps of a system are carried simultaneously, and flow rate of water flow will be too high, and tube wall has the carmine danger of growth, and product quality also can not get ensureing.Can open simultaneously two water pumps if select the water pump of low discharge for use and guarantee that system's flow rate of water flow can be not too high, but be in operation, when a certain water pump broke down, a remaining water pump can not satisfy water supply requirement, system's flow rate of water flow can not satisfy, and also can not guarantee product quality.And open when the 1# water pump, 2# water pump offline standby (the valve place separates pipeline before and after the pump) then can occur when 1# water pump fault, and the 2# water pump will come into operation and then need sterilization again, and consuming time longer, the production continuity can't ensure.Therefore need to consider the stable continuous operation problem of the circulating system.
