[Sell] Liquid ring vacuum units 2BW serier View details for: Liquid ring vacuum units 2BW serier
Liquid ring vacuum units 2BW serier The water ring vacuum pumps are used widely in chemical and pharmacy areas for its characteristics of the work principle and structure. Normally, the operating liquid of the water ring vacuum pumps is almost discharged out directly or drained into the large circulation pool. By this way, the connection for suppling and discharging the water is very simple and easy to operate, so it is used commonly in the practice. But to discharge the operating liquid out directly has some disadvantages as the following items when the pumped medium contains the organic solvent or poisonous substance: 1.When the water ring vacuum pump works, the pumped gases and the operating water are mixted. So the discharged water contains a lot of solvent or poisonous subtance. Further, the more the discharged water, the more heavier pollution to the environment. 2.The water containing the solvent or poisonous subtance will set out a lot of harmful gases and increase the environment pollution. 3.The pumped solvent is not easy to reclaim and that causes lots of waste. For these above reasons, more and more chemical and pharmacy enterprises choose to use the 2BW series package units. The 2BW package unit is composed of 2BV or 2BE series liquid ring vacuum pumps, seperators, heat exchangers, pipes, valves, etc. Comparing with the single liquid ring vacuum pump, the installaion of the package unit is more convenient. Because the working liquid circulates, to use the closed system can decrease the consumed liquid volume and reduce the environment pollution efficiently. So the advantages are more obvious when the pumped gases contain organic solvent or poisonous substance. In fact, the 2BW package unit can be used widely in many conditions.

[Sell] Roots water ring vacuum pump unit View details for: Roots water ring vacuum pump unit
Roots water ring vacuum pump unit Summary: JZJ2B series Roots water ring vacuum unit is composed of ZJ Roots vacuum pump as the main pump and 2BV or 2BE water ring vacuum pump or Roots water ring unit as the fore pump, It not only can suction the general gases, but also can suction the other gases that contain moisture or a small quantity of dust. Compared with the general mechanical vacuum pump, it is not easy to be polluted by oil, moisture and dust. And compared with general water ring vacuum pump, it has higher vacuum and bigger pumping speed when it works in the high vacuum. Several types of the package units: Roots pump+water ring vacuum pump:The function of the water ring vacuum pump is to form the pre-vacuum for the Roots pump. Presently, water ring vacuum pump 2BV,2BE1 with higher ultimate vacuum degree are mostly used as fore pump. Roots pump+Roots pump+water ring vacuum pump:When use one set of the Roots pump, especially connecting with the water ring vacuum pump, the limited vacuum of the whole unit is much lower with the restricted scope . But to use two sets of the Roots pumps in series and connect them with the water ring vacuum pump can improve the whole limited vacuum effectively. Roots pump+Roots pump+Roots pump+water ring vacuum pump:If the two Roots pumps and the water ring vacuum pump unit still dose not satisfie the requirements of the vacuum , another Roots pump can be added. These series Roots units are used extensively in some high vacuum technics of the vacuum freezing or dry process. Normally, to choose the water ring vacuum pump as the fore pump is better than to choose the others because the following reasons: Firstly, the water ring vacuum pump can pump plentiful coagulable steam. And this advantage is more obviously when use the gas-down and oil seal mechanical vacuum pump as the fore pump because it is poor in pumping the coagulable steam. Secondly, to use the solvent as the operating liquid will make the oil bad. Sometimes, the system is not allowed the pollution. Furthermore, to choose the package units, it is necessary to make the working vacuum five or ten times of the limited vacuum in order to achieve the best performance of the package units. i.e. working vacuum>=limited vacuum *(5~10).

The 2BE3 series pumps have flanges both on the top and sides with the same diameter. It is more convenient to connect with the 2BE3 series pumps. The bearings are all used of the imported products in order to keep the precise orientation and the high stability during the working of the pump. The material of the impeller is QT400 nodular iron or steel plates for ensuring the stability of the pump under the various rigorous situation and extending the life of the pump effectively. The casing is made of steel or stainless steel plates to extend the lifetime of the 2BE3 series pumps. The shaft bushing is made of stainless steel plates to extend the life of the pumps 5 times more than the normal material. The V-belt pulley (when the pump is driven by the belt) is used of the high precise pulley with taper bushing to keep the reliability of the pump and extend its life. And it is also easy to mantle and dismantle. The unique design of setting the separator above the pump saves the space and decreases the noise efficiently. All the spare parts are cast by the resin sands that makes the surface of the pump very smooth. So it is not necessary to cover the surface of the pump with putty and gives out the heat efficiently.

[Sell] water ring vacuum pump 2BV5 View details for: water ring vacuum pump 2BV5
Liquid ring vacuum pump 2BV5 2BV5 series water ring vacuum pumps are suitable for pumping the gases and steam. Its suction pressure can reach 33mbar (abs) (i.e. 97 % vacuum degree). If the transformer oil is used as the operating liquid, these pumps are called oil ring vacuum pump and the suction pressure can reach 6.7mbar (abs) (i.e. 99 % vacuum degree). So the oil ring vacuum pumps can replace the reciprocated vacuum pumps completely. When the liquid ring vacuum pumps work under the condition near the limited vacuum for a long time, it is necessary to couple with the cavitation protection pipe in order to get rid of the screaming and protect the pump. When the compressors work, the maximum pressure is 0.26MPa(abs). And the higher of discharge pressure, the larger of the power of the compressors. So it is necessary that the data of the discharge pressure is provided to choose the proper motor. 2BV5 series water ring vacuum pumps and compressors will replace the SK and 2SK series water ring pumps and the W, WY, WL series reciprocated vacuum pumps completely with their superior performance and advantages.

When the ZF unit starts, one pump begins to work.

When the ZF unit starts , the vacuum pump works till the vacuum in the container reaching the highest vacuum. And when the vacuum in the container is lower than the lowest vacuum, the vacuum pump works again automatically. The vacuum pump can also be switched to manul control for on and off. Performance characteristics: After starting the ZF package unit, it works automatically in the whole process. During its operating process, the vacuum in the vacuum system always waves among the allowed scope and its waving scope can be adjusted by the customer's requirement. If the vacuum is lower than the setting value, the alarm will give out the warning. ZF package unit can achieve automatic control without manual operation and can close the vacuum system automatically if the power is off. Fix a separator in the ZF package unit so as to save the water and reduce the environment pollution. The vacuum container can be designed with horizontal or upright struction according to the practical situation. So the installation is more flexible

But to use two sets of the Roots pumps in series and connect them with the water ring vacuum pump can improve the whole limited vacuum effectively. Roots pump+Roots pump+Roots pump+water ring vacuum pump:If the two Roots pumps and the water ring vacuum pump unit still dose not satisfie the requirements of the vacuum , another Roots pump can be added. These series Roots units are used extensively in some high vacuum technics of the vacuum freezing or dry process. Normally, to choose the water ring vacuum pump as the fore pump is better than to choose the others because the following reasons: Firstly, the water ring vacuum pump can pump plentiful coagulable steam. And this advantage is more obviously when use the gas-down and oil seal mechanical vacuum pump as the fore pump because it is poor in pumping the coagulable steam. Secondly, to use the solvent as the operating liquid will make the oil bad. Sometimes, the system is not allowed the pollution. Furthermore, to choose the package units, it is necessary to make the working vacuum five or ten times of the limited vacuum in order to achieve the best performance of the package units. i.e. working vacuum>=limited vacuum *(5~10).
