Embodiment Construction

[0012] The lubricating oil centralized recycling system for preventing oil pump suction of the present invention includes an oil tank 1, an oil pipe 2, a double gear pump 4 that sends the lubricating oil from the clean chamber 1a of the oil tank 1 to the lubrication point 3, and transfers the lubricating oil to the lubricating point 3. The oil is sent back to the oil return pump 5 in the dirty oil chamber 1b of the oil tank, and the lubricating oil deposited in the dirty oil chamber 1b of the oil tank is pumped into the circulating gear pump 6 in the clean chamber 1a, and a preventive oil pipe is installed on the oil pipe from the double gear pump 4 to the lubrication point The suction branch 7 and the anti-cavitation branch 7 are connected to the double oil return pump 8 and the single oil return pump 9 . A speed regulating valve 10 is also set on the suction branch 7, and the speed regulating valve 10 is connected with a progressive distributor 11, and the progressive distrib...

Abstract

The invention relates to a lubricating oil focus cycle utilization system for preventing oil pump suction. The lubricating oil focus cyclic utilization system comprises an oil box, an oil pipe, a gear pump, an oil return pump, a cycle gear pump and a suction prevention branch circuit, wherein the gear pump is used for sending lubricating oil from a clean cavity of the oil tank to a lubricating point; the oil return pump is used for sending lubricating oil of the lubricating point back to a sump oil cavity of the oil tank; the cycle gear pump is used for pumping lubricating oil precipitated in the sump oil cavity of the oil tank into the clean cavity; the suction prevention branch circuit is arranged on the oil pipe from the gear pump to the lubricating point and connected with the oil return pump; and the suction prevention branch circuit is connected with a progressive distributor which is connected with the oil return pump. After the structure is adopted, the lubricating oil focus cycle utilization system for preventing the oil pump suction can be used for effectively preventing the oil pump from having a suction phenomenon so as to prolong the service life of the oil pump, reduce the maintenance cost and enhance the lubricating effect.

Description

technical field [0001] The invention relates to a lubricating oil circulation system, comprising an oil tank, an oil pipe, a gear pump for sending the lubricating oil from a clean chamber of the oil tank to a lubricating point, and an oil return pump for sending the lubricating oil at the lubricating point back to the dirty oil chamber of the oil tank. The lubricating oil deposited in the dirty oil chamber is pumped into the circulating gear pump in the clean chamber. Background technique [0002] The air suction of the oil pump mainly means that the oil sucked by the oil pump is mixed with air. This situation is not only prone to cavitation and increased noise, but also affects the volumetric efficiency of the oil pump and makes the working oil easy to deteriorate. The function of the oil return pump in the lubricating oil system is to send the lubricating oil from the lubricating point back to the oil tank, and the lubricating oil at the lubricating point often has a smal...
