1. The way oil enters the water (1) The fuel tank cover due to alternating hot and cold and make the water in the air condense into water droplets fall into the oil. (2) The cooler or heat exchanger seal is damaged or the cooling tube ruptures causing the water to leak into the oil. (3) through the hydraulic cylinder piston rod seal is not tight into the system of moist air condensed into water droplets. (4) When the oil with human water and oil exposure to wet conditions and affinity with...
Screw pump hydraulic anti-reversing technology is to prevent the conventional screw pump wells in the shutdown or card pump column reversal, resulting in off the rod, polished rod rejection bending, ground equipment damage and other issues of technology. Screw rod pump often shut down after the pole reversal phenomenon occurs, the pole of the internal storage of torsional potential energy and the oil pressure differential may lead to pole reversal. Sudden release of the sucker rod torque, by...
Oil mixed with various impurities in the oil particles in the form of solid-state pollutants exist. Some of these impurities are the components of the process of processing and assembly residual, some are generated during the hydraulic components in the course of work, and some from the outside world intrusion of impurities, the harm is: 1. Oil in a variety of particulate impurities will pump and motor caused harm. When the foreign particles into the hydraulic pump gear or gear motor gear end...
