Universal three-screw pump with wide application
1.The screw units is rotating along with the external prime mover.
2.The spiral groove of the screw opens periodically,and the volume of suction cavity increases,resulting into a vacuum.
3.The medium is absorbed into the spiral groove and sealed in the spiral groove.
4.Along with the rotation of screw,the medium moves toward the outlet along the axial line of the screw.
5.The medium is pumped out.This is the operating principle of screw pump.
Performance Viscosity:3.0 ~ 1500 mm2/s
Flow:5 ~ 5300 L/min
Maximum Pressure:4.0 Mpa
Maximum Temperature:150 ℃
Oil type screw pump:
1. Oil pumps are suitable for transporting all kinds of oils, such as light oil, diesel oil and lubricating oil. Copper gears can be used to transport low-point liquids, such as gasoline, benzene, etc. Our unit also produces stainless steel gear pumps for transporting beverages and corrosive liquids.
2. Various pump types of oil pump are simple and compact, easy to use and maintain, and have good self-priming property. It helps not to inject liquid before starting each pump.
3. The lubrication of some oil pumps is automatically achieved by transporting liquid, so no additional lubricant is needed in daily work.
4. Using the elastic coupling to transfer power can compensate for the small deviation caused by the installation of the oil pump. When the pump is inevitably impacted by hydraulic pressure, it can play a better buffer role.
Many advantages of screw pump make the application scale of screw pump oil production technology in China's oil field increasing year by year. It has developed into a very common manual lifting method, which can slow down the investment of funds, reduce the cost of oil field production, and better meet the needs of the development of lifting technology. Of course, any technology is not always advantageous or harmless. As a relatively new technology, screw pump oil production technology has many advantages, but there are also some shortcomings. Screw pump needs high viscosity fluid to lubricate, otherwise it is very easy to cause damage to the stator of pump barrel. Although screw pump oil production technology is simple to operate, it needs high accuracy, otherwise it is easy to build. The stator life of the screw pump is not high due to the damage of the finished pump. It needs to be checked many times and the cost of testing is high. In the process of application, it is necessary to develop the advantages and avoid the disadvantages, and gradually improve the screw pump well production technology, so as to play its greatest role and bring higher benefits for oil exploitation.
