Common Faults and exclusion method stainless steel external gear pump

Air is sucked into the common faults of stainless steel gear pump, following the first volume of the air sucked into this fault exclusion method: Pump with stainless steel end caps on both sides of the gas transfer pump in direct contact with a hard seal, if the flatness of the contact surfaces do not meet requirements, the work of the hydraulic piston pump when air is sucked into the easily; Similarly, the pump and the pressure cap also for direct contact between the cover, the air is easily invade into; If the gland is plastic products, due to its damage or deformation due to temperature changes, but also make Mifengbuyan enter the air. Exclude this failure is: when the flatness of the pump or manual fuel transfer pump cover less than the specified time, you can press shaped route from grinding on the plate with emery also be on the surface grinder grinding to flatness of not more than 5μm, and the need to ensure that the vertical plane of the hole which requires; leakage and the gland to the pump at the head, can be coated with an adhesive such as epoxy resin for sealing.
