Basic Info

Model No.:  TM-001

Product Description

Model NO.: TM-001 Operating Speed: Adjust Speed Magnetic Structure: Permanent Magnet Structure: Compact Structure Ventilation: Protection Type Brand: Tianan Electric Rated Torque: 53000 Nm Rated efficiency: 95% Temperature Rise: 40 K Core length: 720 mm Specification: 33kW Application: Industrial, Beam Pumping Unit Operation Mode: Electric Motor Function: Driving Number of Poles: Three-Phase Certification: CCC, ISO9001 Rated power: 33kW Rated speed: 6 rpm (0~6 rpm CVT) Rated current: 65 A The outer diameter of the core: 990 mm Trademark: Tianan Electric Origin: Zhejiang Ningbo Electric Motor Direct Drive Beam Pumping Unit

1.Working Mechanism
        Working Mechanism straight to beam pumping unit are: using a low speed high torque permanent magnet motor complex, to replace the original prime mover, belts and reduction gearbox, direct drive beam pumping unit.
2. Drive Features
        Direct drive permanent magnet beam pumping unit only Composite Motor driving a rotating part. Natural cooling temperature does not exceed 40K, effectively guarantee the long-term stable operation of the motor. Rotor torque is transmitted without contact, there is no mechanical wear, no lubrication.
        Low rotor speed, bearing cylindrical roller bearings, high radial load carrying capacity, life expectancy is higher than the mechanical gearbox.
        Without changing the existing infrastructure at the same volume and the reduction gear box torque specifications fairly, so the traditional beam pumping unit direct drive transformation can be directly under the original design specifications of the reduction gear box and spindle motor base directly primordia seat installation. Run smooth, quiet.
3. The device features:
>>3.1 Maintenance-free
        The device design and manufacturing time, fully take into account the full advantage of the existing pumping and learn to be less than the original pumping full optimization. Pumping would not have accidents due to replace the belt, adjustment of stroke caused by making improved. A series of maintenance trouble eliminating the gearbox oil spills, maintenance and so on. Therefore, the device is a revolution in the oil industry.
>>3.2 low-cut speed can be continuously adjusted
        Direct drive motor output speed (0 to 10) between r / min, speed continuously. RMS reservations decimal place.
>>3.3 Comprehensive energy-saving rate
        Standard wells by the National Certification Commission for Certification of metering energy monitoring agency issued the "energy-saving test report" given comprehensive energy-saving rate of 16.53%.
>>3.4 Average system efficiency
        The average system efficiency standard wells by the National Certification Commission for Certification of metering energy monitoring agency issued the "energy-saving test report" given increase 3.19 percentage points.
>>3.5 brake mechanism
        Direct drive motor output shaft mounted brake mechanism. Ensure the safety parameter adjustment when operating.
>>3.6 Overs
        When pumping parameter adjustment operations, direct drive motor in a hovering state, direct-drive motor output of the braking force is greater than equal to the motor torque.
>>3.7 Easy installation
        Direct drive motor is directly connected to the output shaft of the crank, the base and the cylinder fixing bolts. Easy to install.
4. beam pumping unit straight drive means advanced:
>>4.1 Advanced unique to the world that the permanent magnet motor drive system that uses no position sensor, extending motor life, reduce points of failure. Reduce motor complex parts.
>>4.2 The drive uses the company's unique operating system. The operating system has a lot of upgrades and expansion space, and equipment compatible with all smart fields, such as: full level control, remote operation and monitoring.
>>4.3 The overload apparatus having automatic adjustment of the torque output range, low load or no-load current is automatically reduced to stop power supply, so as to achieve maximum power saving purposes.
>>4.4 The device is equipped with a feedback unit interface that can be caused by excessive power balancing feedback network.
