2BE3 400 Liquid Ring Vacuum Pump
The application range and characteristics:
2BE3 series liquid ring vacuum pumps and compressors are designed and manufactured by our company integrating with the advanced technology abroad. They are not only can save energy, but also can work constantly for a long time.
Under the rough vacuum situation, the requirements for the liquid ring vacuum pumps are very rigorous. So the 2BE3 series products are designed for pumping various gases. They are widely used in many industries, such as, the paper, mine, power station, chemical etc.
2BE3 series products can be driven with many different sets, such as, the V-belt, synchronal motor, gear box etc. In order to save space, more than two or at most four sets of the 2BE3 series pumps can be driven by one motor simultaneously.
When set a middle wall in the casing, the pressure tolerance between the two sides is lower than 80kPa and the two parts can work in different vacuum status respectively. Thus one pump can work well like two. Hereby the product operating flexibility is improved effectively.

Greentech International (Zhangqiu) Co., Ltd is the professional roots blower supplier. RZSW-40 submerged roots blower on the basis of the manufacture and sale of a Roots blower for many years the development of new products using new technology.

The machine through the use of new lines on the impeller, the overall adiabatic efficiency and volumetric efficiency is further improved, and is excellent particularly in the fan of the air volume and pressure characteristics.

Quiet

Because the blower is installed under water the operatingnoises reaching the surface of water are refracted into waterinstead of air. Meanwhile.water and tank walls also refract thenoises into water. In this way, noises are effectively reduced.

NO Need to Add Soundproofing DevicesBeing installed under water, the blower produces less noises.So, there is no need to add a soundproofine cover or build asoundproofing factory, Besides, since it is installed in a watertank, it does occupy space, The work place can be utilizedmore efficiently,

Sturdy Structure to Ensure Durability

The motor and the blower body are connceted directly(toavoid the troublesome conveyer adjudtmet of the traditionatype of connection), The motor and the blower body areentirely sealed with an o-ring so water will not wet the motor, lfthe motor stops due to overheating, tear Off its outer case toradiate heat more effectively.

Main Features:
1)Low noise
Because the blower is installed under water, the operating noises reaching the surface of water are refracted into water instead of air. Meanwhile, water and tank walls also refract the noises into water. In this way, noises are effectively reduced. SRB series will be applied to school, building, community and hospital.
2) Easy installation
JSL series are not necessary to fix on foundation, saving piping cost. Being installed under water, so there is no need to add a soundproofing cover. Besides, since it is installed in a water tank, it doesn't occupy space. The work place can be utilized more efficiently.
3)Less trouble
It is not necessary for belt and pully because SRB series design directly drive system for raising high efficiency and reducing failure factor.
4) Motor
Using squirrel-cage induction motor, with F class insulation and IP68 motor protection grade, Build-in overheating detector in motor, it can prevent the motor from burning out.
5)Filtration device
Dry type. It won't distort even by sudden pressure rise or absorption force. The area of filtration device is 1.2 times than the air capacity of blowers. It can control the pressure loss less than 25mmAq.

Air Suspension Bearing:
Air suspension bearings use air buoyancy instead of lubricating oil, and use the surrounding air instead of lubricating oil, so they can operate at higher temperatures and high speeds. The advantages of air suspension bearings are flexible start-up and low-cost operation, no mechanical friction, no lubricating oil, no vibration, low noise, and long life.
When the blower starts, the bearing is in contact with the shaft, and when it reaches the take-off speed, the bearing and the shaft are non-contact, frictionless, and the rotor is in a suspended state.
Widely used in aeration, pressurization, gas transportation, drying extraction, purification, vacuum packaging, solution recovery, gas phase separation and other processes in various industries
Performance characteristics:

1. High efficiency and energy saving
More than 30% power saving than traditional Roots blower
More than 20% power saving than multi-stage centrifugal fans
More than 10% power saving than single-stage high-speed fan

2. Maintenance-free
Skid-mounted structure, no need to install the foundation. Daily work only needs to replace the filter and is basically maintenance-free.

3. Low noise
No mechanical noise, active sound insulation of the cabinet, the overall operating noise is about 80dB.

1.2BX series pressure relief valve is all metal structure, pressure relief valve spindle, adjustment nut and spring are made of steel.The other components are made of aluminum alloy,
2.Pressure relief repeat accuracy of 2BX4 pressure relief valve reaches 5%.Pressure protection is reliable

The reief valve is nstalled on inlet or outlet of side channel blower.
1.when the working pressure or pressure surge inside the bloweris overload than the rated pressure of side channel blower , the relief valve will be open within 0.2 minutes , the overload pressure wilbe released from relief valve in order to protect the blower
2. when the working pressure reduces to safe value , the valve wil be closed slowly, this will not cause the pressure surge again .
3.Pressure relief valve can be used in either pressure state or vacuum state.

This is a material pressure pneumatic system, which adopt Roots blower as generator, rotary feeder as a feeding facillty.The system has features of low pressure, short transporting distance, reliable is suitable to convey from one place to muli-place, and realize the function of diying and classficiation to material.The outside air or rain water is not ableto enter the system even f there
is an aperture in connection site some-where in pipe system, his should be due to the positive in the system.

For all kinds of plastic powder mixing, drying, coloring and otherprocesses, The unit consists of one hotmixer and one cooling mixer, is the ideal choice for the production of profiles, pipe manufacturers.
is the basic equipment of PVC pipe/profile/board, PVC foam board making machine.
2.All important components(Pan, agitator, distribution box, etc.) are manufactured inside the company to ensure the quality of the machines.3.The mixer lid is double sealed and opened in the pneumatic way.
4.The abrasion resistant coating of the stirring paddle increases the service life, and runs smoothly throungh the static and dynamic balance test.
5.Barrel wall undergoes precise grinder.
6.Thermo control meters adopt RKC from Japan.

MF-32 Filler Breather Filters

This filter is made of cylindrical stainless steel mesh, which has high ventilation, does not affect the flow rate of the fan, and is easy to clean and maintenance-free.
