 Trouble shooting of the gear lubrication pump |
CB-B gear lubrication pump control mechanism of the dump truck and construction machinery use more now Common Faults and exclusion method described below for reference. 1, vibration and noise reasons and exclusion
(1) inhalation of airborne
CB-B gear lubrication pump, pump and both sides of the end cap for direct contact with the seal, if the flatness of contact surface do not meet requirements, easy to inhale the air pump at work; Similarly, the pump cover and gland between direct contact with the air intrusion; if the gland for plastic products, due to damage or deformation due to temperature changes, but also make Mifengbuyan into the air. Exclude this fault is: when the pump or pump cover a flatness of less than the requirements in the plate with emery "8" shaped route back and forth grinding, but also on the surface grinder grinding its flatness of not more than 5µm, and the need to ensure that the vertical plane with the hole degree requirements; pump cover and gland at the leak, can be coated with epoxy resin adhesive seal.
seal on the shaft is generally skeleton oil seal. Clamping lip spring fall off or encapsulated anti-oil, or lip injury, aging, will make the oil seal back-end is often in a vacuum state, the air inhaled, and can be replaced with new oil seal to be addressed.
the fuel tank of fuel is not enough, or mouth of the suction pipe is not plugged in to the oil below, the pump will draw in air to the fuel tank to supplement the oil to the oil marking; if the return pipe mouth exposed oil surface, sometimes due to instantaneous negative pressure within the system make air anti-irrigation into the system, so the return line port should generally also be inserted into the oil below.
The
pump installation location away from the oil level is too high, especially when the pump speed is reduced, because they can not ensure that the pump suction chamber vacuum caused by oil absorption and inhalation of air. You should adjust the relative height of the pump with the oil surface to meet the requirements.
The
suction filter was clogged by dirt or capacity is too small, resulting in oil absorption resistance increase in inhaled air;, into the larger diameter of the outlet may be brought into the air. At this point, cleaning the oil filter, or select a larger capacity, and import and export of the appropriate diameter of the oil filter. So, not only can prevent the inhalation of air, but also to prevent noise.
(2) mechanical reasons
Requirements the
pump and connection to the coupling due to the irregularities arising from the vibration and noise.
