The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides an even oil suction device of many oil pumps, includes the oil tank, sets up four at least heating pipes in the oil tank to and the oil-out, the oil pipe of oil-out intercommunication, the last at least three oil pump of intercommunication of oil pipe, the mouth of pipe of one of them heating pipe sets up out oil pipe mouth I and replaces this heating pipe, goes out oil pipe mouth I and communicates out the end of oil pipe through oil pipe I.

According to the multi-oil-pump balanced oil suction device, the pipe opening of the other heating pipe is provided with the oil outlet pipe opening II to replace the heating pipe, and the oil outlet pipe opening II is communicated with the tail end of the oil outlet pipe through the oil pipe II.

In the balanced oil suction device with multiple oil pumps, the nominal diameter of the oil outlet pipe is 125 mm, the nominal diameter of the oil pipe I is 80 mm, and the nominal diameter of the oil pipe II is 80 mm.

According to the multi-oil-pump balanced oil suction device, the heating pipe is removed, and then the pipe orifice of the heating pipe is set to be the oil outlet pipe orifice.

Compared with the prior art, the beneficial effects of the utility model are that, the utility model discloses utilize the mouth of pipe of oil outlet pipe replacement heating pipe, set up the oil circuit and provide the fuel feeding compensation to the oil pump, avoided the oil pump to rob oily phenomenon each other for the oil pump can balanced oil absorption, has improved the life of oil pump, makes system's pressure obtain stably, has reduced the shutdown fault rate of equipment.

Fig. 1 is a schematic view of the present invention.

Wherein 1 is a fuel tank; 2 is a heating pipe; 3 is an oil outlet; 4 is an oil outlet pipe; 5 is an oil pump; 6 is an oil outlet pipe orifice I; 7 is an oil pipe I; 8 is an oil outlet pipe orifice II; 9 is an oil pipe II; 10 is a removed heating pipe I; 11 is a working unit; 12 is a removed heating tube II.

Detailed Description

As shown in fig. 1, a balanced oil suction device of many oil pumps, including oil tank 1, set up four at least heating pipes 2 in the oil tank 1 to and oil-out 3, go out oil pipe 4 of 3 intercommunications of oil-out, go out at least three oil pump 5 of intercommunication on the oil pipe 4, set up out oil pipe mouth I6 at the mouth of pipe of one of them heating pipe and replace this heating pipe, go out oil pipe mouth I6 and pass through the end that oil pipe I7 intercommunicated out oil pipe 4, provide the fuel feeding compensation for the terminal oil pump of play oil pipe 4, realize the balanced oil absorption of oil pump.

Foretell balanced oil suction device of many oil pumps sets up out oil pipe mouth II 8 at the mouth of pipe of another heating pipe and replaces this heating pipe, goes out oil pipe mouth II 8 and passes through the end of oil pipe II 9 intercommunication oil pipe 4, provides bigger compensation flow for the terminal oil pump of oil pipe 4 for the balanced oil absorption of a plurality of oil pumps.

In the balanced oil suction device for the multiple oil pumps, the nominal diameter of the oil outlet pipe 4 is 125 mm, the nominal diameter of the oil pipe I7 is 80 mm, the nominal diameter of the oil pipe II 9 is 80 mm, and a pipeline with enough diameter is arranged to meet the oil suction requirement of the oil pump 5.

The working process of the utility model is as follows: as shown in fig. 1, hydraulic oil in an oil tank 1 is heated by at least four heating pipes 2 arranged in the oil tank 1, and enters an oil outlet pipe 4 communicated with an oil outlet 3 from the oil tank 1 through an oil outlet 3, the hydraulic oil enters at least three oil pumps 5 connected in parallel through the oil outlet pipe 4, and the oil pumps 5 supply the hydraulic oil to a working unit 11 to meet the unit operation requirement. Meanwhile, the nozzle of one heating pipe is provided with an oil outlet nozzle I6 to replace the heating pipe, so-called replacement is to remove the heating pipe and then set the nozzle of the heating pipe as the oil outlet nozzle I6, hydraulic oil enters the oil outlet pipe 4 through the oil pipe I7 communicated with the tail end of the oil outlet pipe 4 through the oil outlet nozzle I6, oil supply compensation is provided for an oil pump 5 communicated with the oil outlet pipe 4, and the oil pump 5 can suck oil in a balanced manner.

The oil supply capacity is further improved, an oil outlet pipe opening II 8 is arranged at the pipe opening of another heating pipe to replace the heating pipe, so-called replacement is that the heating pipe is removed, the oil outlet pipe opening is arranged as an oil outlet pipe opening II 8, hydraulic oil enters the oil outlet pipe 4 from the oil outlet pipe opening II 8 through an oil pipe II 9 communicated with the tail end of the oil outlet pipe 4, and therefore larger compensation flow is provided for the oil pump 5 communicated with the oil outlet pipe 4, and the oil pump 5 can absorb oil in a balanced mode.

The broken line 10 in fig. 1 indicates the position of the removed heating tube i 10 before removal, and the oil outlet i 6 is provided at the tube opening of the heating tube instead of the heating tube, and the oil outlet i 6 is provided at the tube opening after the heating tube is removed. The broken line range 12 in fig. 1 indicates the position of the removed heating tube ii 12 before removal, and the oil outlet ii 8 is provided at the tube opening of the heating tube instead of the heating tube, and the replacement is that the tube opening is provided as the oil outlet ii 8 after the heating tube is removed.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
