Normally, the operating liquid of the water ringvacuum pumps is almost discharged out directly or drained into the large circulation pool, as Figure 1.Figure 1 Supply and discharge of operating liquid for normal water ring vacuum pumpWater ring vacuum pump to discharge water into a large circular pool or discharged directly. This way ofwater supply and drainage connection is convenient, simple to use, is mainly used in the practicalapplication.But to discharge the operating liquid out directly has some disadvantages as the following items whilethe pumped medium contains the organic solvent or poisonous substance..While the water ring vacuum pump works, the pumped gases and the operating water are mixed. Sothe discharged water contains a lot of solvent or poisonous substance. Furtherthe more the discharged water, the heavier pollution to the environment..The water containing the solvent or poisonous substance will set out a lot of harmful gases andincrease the environment pollution.. The pumped solvent is not easy to reclaim and that causes lots of wasteFor these above reasons, more and more chemical and pharmacy enterprises choose to use the 2BWseries package units.Main characteristics of the liquid ring vacuum pump closed loop system:1. to shorten the installation period of the customer to use the whole set of the system which includesthe pump, separator, heat-exchanger, frame and pipeline etc.2. to decrease the environment pollution efficiently while the working liquid is the various solvent.3. If use the pumping medium as a working fluid, pumping medium by recycling. 4. the 2BW series vacuum system is non-standard products of our company, they are designed by the practice conditions of the inlet port, cooling water and discharge port etc.Working principle: The most basic 2BW series liquid ring vacuum pump / compressor closed loop system is shown in Figure 2: By pumping the gas from the suction port into the liquid ring vacuum pump / compressor, the liquid ring vacuum pump / compressor and liquid together into a gas-liquid separator, gas-liquid separator in gas-liquid two-phase separation, gas discharged from the exhaust port, working fluid by heat exchanger is liquid ring pump / compressor suction for recycling. Liquid ring vacuum pump in the working process will produce heat, heat mainly include: vacuum pump / compressor reactive power; inhalation caused by higher gas temperature heat; inhaled gases containing condensable gases in the process of compression release phase change heat. For the main purpose of the heat exchanger is by a cooling water cooling liquid, the working fluid temperature is kept within a reasonable range.Composition of equipment: The main components of the closed loop system of liquid ring vacuum pump /compressor are included: . Liquid ring vacuum pump / compressor . Gas-liquid separator . Heat exchanger . Common chassis . Internal pipelineFAQQ: What's your MOQ?A:One set;Q: What are the causes of no flow or insufficient flow of centrifugal pump?A:There is air in the suction pipe or pump, which needs to be discharged. Air leakage is found in the suction pipeline, and the leakage is repaired. If the valve of suction line or discharge line is closed, relevant valve shall be opened. If the suction height is too high, recalculate the installation height. The suction line is too small or blocked.Q: How to resist cavitation in centrifugal pump?A: Improve the structure design from the suction to the impeller of the centrifugal pump;Adopt double stage suction impeller and use anti-cavitation material;Q:What is the function of rubber ball in water ring vacuum pump?A:Rubber ball in water ring vacuum pump, the correct name is called rubber ball valve. Its role is to eliminate the pump equipment in the operation process of the phenomenon of over compression or insufficient compression.Q:How long is warranty?A:One year formain construction warranty.Q:How can I pay for my items? What is the payment you can provideA:Usually by T/T, 30%-50% deposit payment once PI/Contract /confirm/ied, then the remaining balance will be paid after inspection and before shipment via T/T or L/C;welcome client from home and abroad to contact us for future cooperation.Detail size drawing and install drawing please contact our sales in charge to get;
