Description
Technical field
The utility model relates to and uses different main pumps to provide the technical field of pressure oil-source in same hydraulic system, specifically a kind of double pump work switched system.
Background technique
At present, structural type equipment adopting multiple power system coexist gets more and more, and hydraulics is widely used on various operating mode equipment simultaneously.Comprehensive above-mentioned technology, adopting multiple power system to drive many pumps to be respectively same hydraulic system provides pressure oil-source to become a kind of trend; Shuttle valve group according to large discharge, high pressure provides pressure oil-source, and cost of production will be made significantly to increase.
Summary of the invention
The purpose of this utility model is the deficiency in order to overcome above-mentioned technology, the double pump work switched system providing a kind of structure simple, easy to manufacture, with low cost.
The utility model solves the problems of the technologies described above taked technological scheme: a kind of double pump work switched system, comprise front pump, rear pump, front one-way valve, rear one-way valve, oil gathering block, hydraulic oil container, it is characterized in that: hydraulic oil container has front pump and rear pump, front pump there is front one-way valve, rear pump has rear one-way valve, and front pump is connected with oil gathering block with rear one-way valve respectively by front one-way valve with rear pump; During front pump work, front pump sucks fluid from hydraulic oil container, pumps to oil gathering block by front one-way valve, and oil gathering block is to hydraulic system fuel feeding, and rear one-way valve cuts off fluid; During rear pump work, rear pump sucks fluid from hydraulic oil container, pumps to oil gathering block by rear one-way valve, and oil gathering block is to hydraulic system fuel feeding, and front one-way valve cuts off fluid.
When described front pump is different with rear pump work, front pump and rear pump respectively by oil gathering block for same hydraulic system provides pressure oil liquid; During described front pump work, rear one-way valve cut-out pressure oil; During described rear pump work, front one-way valve cut-out pressure oil.
The utility model is reasonable in design, novel, and structure is simple, easily manufactures, cost is low, use, easy to operate, and reliable performance, maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is structure hydraulic schematic diagram of the present utility model.
1, hydraulic oil container, 2, front pump, 3, front one-way valve, 4, oil gathering block, 5, rear one-way valve, 6, rear pump.
Embodiment
As shown in Figure 1, a kind of double pump work switched system, comprise front pump 2, rear pump 6, front one-way valve 3, rear one-way valve 5, oil gathering block 4, hydraulic oil container 1, its hydraulic oil container 1 there are front pump 2 and rear pump 6, front pump 2 there is front one-way valve 3, rear pump 6 has rear one-way valve 5, and front pump 2 is connected with oil gathering block 4 with rear one-way valve 5 respectively by front one-way valve 3 with rear pump 6; When front pump 2 works, front pump 2 sucks fluid from hydraulic oil container 1, pumps to oil gathering block 4 by front one-way valve 3, and oil gathering block 4 is to hydraulic system fuel feeding, and rear one-way valve 5 cuts off fluid; When rear pump 6 works, rear pump 6 sucks fluid from hydraulic oil container 1, pumps to oil gathering block 4 by rear one-way valve 5, and oil gathering block 4 is to hydraulic system fuel feeding, and front one-way valve 3 cuts off fluid.
Work when described front pump 2 and rear pump 6 are different, front pump 2 and rear pump 6 respectively by oil gathering block 4 for same hydraulic system provides pressure oil liquid; When described front pump 2 works, rear one-way valve 5 cut-out pressure oil; When described rear pump 6 works, front one-way valve 3 cut-out pressure oil.
Its concrete working principle is as follows:
When the front pump 2 described in power source drives works, front pump 2 sucks fluid from hydraulic oil container 1, and pumps the hydraulic fluid port a to oil gathering block 4 by front one-way valve 3, and the hydraulic fluid port a pressure oil liquid of oil gathering block flows to hydraulic fluid port b and hydraulic fluid port c; When fluid flows to hydraulic fluid port c, then to whole hydraulic system fuel feeding; When fluid flows to hydraulic fluid port b, one-way valve 5 after fluid flows to, rear one-way valve 5 cuts off fluid, makes pressure oil liquid can not flow to rear pump 6, and the pressure oil avoiding front pump 2 impacts rear pump 6, causes damage to rear pump 6.
When the rear pump 6 described in power source drives works, rear pump 6 sucks fluid from hydraulic oil container 1, and pumps the hydraulic fluid port b to oil gathering block 4 by rear one-way valve 5, and the hydraulic fluid port b pressure oil liquid of oil gathering block flows to hydraulic fluid port a and hydraulic fluid port c.When fluid flows to hydraulic fluid port c, then to whole hydraulic system fuel feeding; When fluid flows to hydraulic fluid port a, one-way valve 3 before fluid flows to, front one-way valve 3 cuts off fluid, makes pressure oil liquid can not flow to front pump 2, and the pressure oil avoiding rear pump 6 impacts front pump 2, causes damage to front pump 2.
Claims (2)
1. a double pump work switched system, comprise front pump, rear pump, front one-way valve, rear one-way valve, oil gathering block, hydraulic oil container, it is characterized in that: hydraulic oil container has front pump and rear pump, front pump there is front one-way valve, rear pump has rear one-way valve, and front pump is connected with oil gathering block with rear one-way valve respectively by front one-way valve with rear pump; During front pump work, front pump sucks fluid from hydraulic oil container, pumps to oil gathering block by front one-way valve, and oil gathering block is to hydraulic system fuel feeding, and rear one-way valve cuts off fluid; During rear pump work, rear pump sucks fluid from hydraulic oil container, pumps to oil gathering block by rear one-way valve, and oil gathering block is to hydraulic system fuel feeding, and front one-way valve cuts off fluid.
