Efficiency in contrast to the Pumping Unit

Into high-pressure airless sprayer pneumatic airless sprayer, electric airless sprayer (piston) and Pumping Unit , the pneumatic airless sprayer with compressed air source along with the have a need to limit the benefits of using pneumatic spraying machine.

Should be electric piston airless sprayer and electric diaphragm airless sprayer to compare, is the Casing Head  driven piston pump plunger movement to re-paint inhalation, when discharge pressure, ready for its exposed plunger and plunger be employed in the paint inside of paint inside of the plunger abrasive wear very quickly, once getting a larger diameter nozzle, the plunger reciprocating frequency increased, increasing plunger wear, short life of this machine.
Airless spray, best quality, smooth and delicate surface, strong adhesion, coating loss and also have less construction, machinery, ships, furniture very well as other industries trusted.

Bell deserve high-pressure airless sprayer which include to the world's leading proprietary technology. Prime Minister booster TM system may very well be restarted and in just a few seconds to load, original suction airless sprayer difficult technical challenges, innovative DAP IV inlet valve stick coating intended reduce the prospect, combined with an elevated motor unit power to resolve, and form a Hydraulic Valves shell, spraying machine capacity building value Bell tasks of short duration, high-volume.
And replace the plunger s incredibly expensive, when voltage just is not normal work will lead directly to the DC's not normal. Top rated, as a result of significant between the two reciprocating motion, piston pump pulse in regards to a great work, making a volatile spray, paint spray concerning the wall roughness isn't really adequate. However, the very first suction Tubing Head are going to be strength rapidly.

Double-horsehead Pumping Unit

• Categories:
• Pumping Unit

• Brand:
• SJ

• API 11E:
• a long stroke

• Update Time:
• 09/23/2012

Detailed Info

Double-horsehead pumping unit is an energy saving product that has a long stroke and low SPM. It is used for pumping oil of middle and high viscosity and high water content.

In addition to the common advantages of conventional beam pumping unit, the unit has advantages of long in stroke length, small in dynamic loads and variation of the torque, high in efficiency, low in energy consumption, smooth in operation and easy in start, etc. A multi-purpose electric cabinet is incorporated in the unit, which has the functions of short circuit protection, overload or underload protection, offset without work, automatic start after power resuming, over speed control of the motor, etc. It is made of the materials cut by numerically controlled flame cutting machines to ensure accuracy and surface quality.

Double horsehead pumping unit is an energy-saving product of long stroke and low frequency of stroke, applicable to the production of medium to low viscosity oil and high water-cut oil.

As compared with the same model of conventional pumping unit, it increases the stroke length by about 70%, reduces energy consumption by 20-30% and decreases unit installed capacity by about 50%.

The unit is new in structure and evident in energy saving. It was taken as a stressed spreading project by CNPC in 1994 and a nationally stressed spreading project in 1995.
