Description

Efficient hydraulic double-cooling loop system

Technical Field

The utility model relates to a die casting machine drive cooling technical field specifically is a two cooling circuit systems of efficient hydraulic pressure.

Background

In the die-casting industry, a cooler is mostly adopted for cooling a cold chamber die-casting machine by water, and the specific cooling mode is system return oil cooling or bypass cooling or the two cooling modes are adopted at the same time; the bypass cooling generally uses an independent motor to cool a main motor and a driver, and then oil returns to the oil tank, and the oil in the oil tank in such a way is hot oil, so that the performance of the whole hydraulic system is affected, and the quality of the oil is also affected in the past.

Therefore, it is necessary to design a device which can ensure the original cooling effect and solve the problem of bypass cooling and oil return, and has lower cost.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming prior art's defect, the utility model provides a two cooling circuit systems of efficient hydraulic pressure, fine promotion hydraulic system's wholeness ability, the quality of fluid and then the life-span of having prolonged fluid in the system among the assurance system, improved work efficiency.

A high-efficiency hydraulic double-cooling loop system comprises an oil tank, a cooling motor pump, a bypass oil filter, a bypass cooler, a driver and a system main motor pump; an oil suction port of the cooling motor pump is connected with an oil tank through an oil pipe, an oil outlet of the cooling motor pump is connected with an oil inlet of a bypass oil filter through an oil pipe, a bypass oil filter, a bypass cooler, a driver and a cooling oil port of a system main motor pump are sequentially connected in series through an oil pipe, and a cooling oil outlet of the system main motor pump is finally connected with a cooling oil return inlet of a machine main system through a one-way valve; the converged oil passes through an oil return tank of a system oil return cooler.

The utility model discloses the structure is ingenious, reforms transform simply, simultaneously fine promotion hydraulic system's wholeness ability, the quality of fluid and then prolonged the life-span of fluid in the system in the assurance system, improved work efficiency.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As can be seen from the attached drawings 1 to 2, the utility model discloses an oil tank 1, cooling motor pump 2, bypass oil filter 3, bypass cooler 4, driver 5, system owner motor pump 6, the oil absorption mouth of cooling motor pump 2 passes through oil pipe 8 and connects oil tank 1, the oil-out of cooling motor pump 2 passes through the oil inlet that oil pipe 8 connects bypass oil filter 3, bypass cooler 4, driver 5 and system owner motor pump 6's cooling hydraulic fluid port establishes ties in proper order through oil pipe 8, system owner motor pump 6 is connected with machine owner system oil return circuit through check valve 7 at last, the fluid after joining returns the oil tank through system oil return cooler 9.

In order to ensure the quality of oil returning to the oil tank 1, the connection among the cooling motor pump 2, the bypass oil filter 3, the bypass cooler 4, the driver 5, the system main motor pump 6 and the check valve 7 is a bypass cooling loop.

In order to ensure the operation effect of the whole system, each component is connected with the oil pipe 8 in a sealing way through a sealing pipe joint.

In order to ensure the cooling effect, the oil pipe 8 adopts a threaded telescopic pipe, is smoothly connected in the connecting process and cannot be bent.

The utility model discloses when specifically using, fluid in the bypass cooling circuit is L1, the fluid that the main system oil returned in the machine system is L2, the fluid that bypass cooling circuit and main system oil returned and converge back is L3, cooling motor pump 2 starts the oil absorption mouth through being connected with oil tank 1 and absorbs fluid from oil tank 1, the fluid of absorption is through the filtration of bypass oil filter 3, get into drive 5 after the cooling of bypass cooler 4 and realize the cooling to drive 5, later get into system owner motor pump 6, the cooling oil-out of last system owner motor pump 6 joins with the main system oil return of machine through check valve 7, and return oil tank 1 behind system return oil cooler 9, realize the cooling to drive 5 and main motor pump 6, specific fluid flows and is: after fluid in oil tank 1 passes through bypass cooling circuit, owing to realized the cooling to driver 5 and main motor pump 6, L1 is hot oil this moment, L2 is the oil of main system usefulness simultaneously, also be hot oil, L1 converges into L3 with L2, L3 returns oil tank 1 after system oil return cooler 9 cools off, can effectually realize that the hot oil after cooling to driver 5 is at oil tank 1 front secondary cooling, the fluid of having guaranteed oil return tank 1 has the temperature that is low enough, and then promote hydraulic system's wholeness ability, the life-span of fluid in the quality extension system of assurance fluid in the system.

In addition, the bypass cooling loop is converged with the main system oil return path through the one-way valve 7, so that the influence of the main system oil return pressure fluctuation on the stability of the bypass cooling oil is well avoided.

The utility model discloses an increased check valve 7 on bypass cooling circuit to return oil circuit with main system before system oil return cooler 9, stopped the fluid that original bypass cooling back was heated directly and returned oil tank 1 when guaranteeing that the stability of bypass cooling fluid is not influenced, the fluid of guaranteeing to return oil tank 1 all is the fluid through after the cooling, and then promotes hydraulic system's wholeness ability, guarantees the life-span of fluid in the quality extension system of fluid in the system.
