Turbine Vacuum Pump

TB series turbine vacuum pump is a new product developed by Zhangqiu wind blower Limited by Share Ltd and Xi'an Jiao Tong University in Shandong province. The aerodynamic performance and structure design of this series of products has reached the advanced level of similar products at home and abroad. It can be widely applied to vacuum systems such as paper machines, vacuum dehydration, Life paper folding machines, vacuum systems, vacuum dedusting and vacuum packaging.

Product Features

The impeller type line is advanced and the efficiency is high.

The use of frequency conversion adjustment, the maximum to meet the needs of the user. At the same time, the anti surge system is equipped to avoid the vacuum pump entering the surge area, and the better protection equipment will not be damaged.

The vacuum pump is compact in structure and small in volume.

Adopting the assembled integral structure, the vacuum pump body is assembled on the shell of the gear increasing box, and the lubricating oil system is arranged in the chassis of the unit tightly. The motor and gearbox are installed on the common base, and the base is also used as the ol tank.

After the rotor is strictly balanced, the vibration is small, the reliability is high, and the whole noise is low.

The rotary inertia of the rotor is small, the starting and stopping time of the unit are short, and no high oil tank and accumulator are needed.

The vacuum pump structure is advanced and reasonable, less vulnerable parts, easy to install, operate and maintain.

Bearing vibration, the temperature rise, the import and export pressure, temperature, anti surge control, start interlock protection, fault alarm, lubrication system oil pressure, oil temperature control adopts programmable logic controller to control the operation of the machine, get real-time monitoring, convenient maintenance.

Main Structure

Impeller According to the three dimension flow theory to the design of high efficiency, the precision machining after strict dynamic balance correction, and through overspeed test 1.15 times the rated speed, ensure the impeller strength. In order to meet the needs of different working conditions, the impeller can be used for many kinds of materials such as forging aluminum, stainless steel and titanium alloy.
High-speed Rotor The high speed rotor consists of the impeller, the high speed gear and the high speed shaft. The impeller is connected to the high speed shaft by the pull rod, and the torque is passed on the end face pin. In order to ensure the smooth and reliable operation of the vacuum pump, the overall balance precision of the high speed rotor is G1.
Vaned Diffuser The wing type diffuser has the advantages of large diffuser, small size, small flow loss and good performance under variable conditions.
Volute Casing The circular section spiral case and the profile of the volute wall are designed as logarithmic spiral lines, which conform to the motion law of the air flow and have little impact on the vacuum pump. Therefore, the vacuum pump has high flow efficiency, small vibration and low noise.
Gear The speed increasing gear pair for the involute tooth shape, the size gear surface is all grind and nitriding hardening treatment, guarantees the vacuum pump to run at high speed steadily, the vibration and the noise are small, the life can reach 20 years.
Bearing High speed bearings with tilting pad sliding bearing is composed of a plurality of pivot deflection activities can be composed of its anti vibration pad, excellent performance, and can be automatically adjusted according to the change of load and speed changes.

Lubricating System

The lubricating system is divided into two parts, the oil tank and the lubricating oil road. The base of the unit is also used as an oil tank, with an immersion electric heater and a temperature transmitter to ensure the temperature of the lubricating oil.

The lubricating oil containing the main oil pump, electric pump, double cylinder filter, main oil pump driven by a low speed gear shaft, the normal operation of the unit can ensure the gear and bearing lubrication oil stabilizing pressure lubrication; electric pump provides for pre lubrication system in unit before the start, keep the oil pressure stable in an emergency and shutdown process, and set aside the effect of oil pump.

The filtration precision of the oil filter is 20 m, and the alarm device of the filter pressure difference is too high.

Monitoring and Control System

The monitoring and control system is specially designed for the operation of turbine vacuum pump. The system has the functions of interlocking of starting conditions, anti surge control, auxiliary pump's automatic start and stop with the change of oil pressure, high bearing temperature and over vibration protection of bearing.

Equipped with oil pressure sensor in vacuum pump oil pipeline, equipped with oil temperature sensor in the cooler, equipped with high-speed sliding bearing temperature, vibration sensor, pipeline with measuring the temperature and pressure of import and export of vacuum pump, a two meter and transmitter, so, real-time monitoring of various operating parameters, ensure the vacuum pump safe, stable and reliable operation.

Performance table of series TB Turbo Vacuum Pump

Remarks:

When the condition of the blower is inconsistent with the upper table, we need to perform the performance conversion. Our company can carry out the non-standard design according to the user's requirements, so as to meet the specific needs of users in all kinds of working conditions.

In order to achieve different vacuum requirements, the turbine vacuum pump can design a double impeller structure.

When transporting corrosive medium, our company will carry out the corresponding anti-corrosion treatment for the inner and impeller of the shell, and change the seal to achieve zero leakage to meet the needs of users.
