Abstract
The utility model discloses a novel hydraulic pump station which comprises an oil tank, a filter, an oil pump, four sets of three-position four-way electromagnetic valves, four sets of jacks and a two-position two-way electromagnetic valve. An inlet of the filter is connected with the oil tank, and an outlet of the filter is connected with the oil pump. The oil pump is connected with an overflow valve, and the oil pump is connected with the four sets of three-station four-way electromagnetic valves in parallel. Outlets of the four sets of three-station four-way electromagnetic valves are respectively connected with a jack, and a converging outlet of the four sets of three-station four-way electromagnetic valves is connected with the two-position two-way electromagnetic valve. A damping hole is arranged in the two-position two-way electromagnetic valve. According to the novel hydraulic pump station, personal errors can be reduced, a pipeline is prevented from being wrongly connected, auxiliary working time is reduced, carrying and installing are convenient, and the novel hydraulic pump station is flexible. Technology content needed in installation is greatly reduced, the number of constructors is reduced, labor intensity is relieved, efficiency is improved, and meanwhile a construction period is shortened.

As shown in Figure 1:
1) synchronization of jacking up: electromagnet DT1, DT3, DT5, the DT7 in four groups of three position four-way electromagnetic valves 5.1,5.2,5.3,5.4 left sides power on simultaneously, and four groups of jack 6.1,6.2,6.3,6.4 pistons stretch out simultaneously, upwards the lifting beam body;
2) descend synchronously: solenoid valve DT2, DT4, DT6, the DT8 on four groups of three position four-way electromagnetic valves 5.1,5.2,5.3,5.4 right sides power on simultaneously, and jack 6.1,6.2,6.3,6.4 pistons are regained simultaneously, following landing beam;
3) jack is unloaded descends: electromagnet DT11 outage, the direct oil sump tank 1 of oil return;
4) jack load descends: electromagnet DT11 powers on, and oil return provides back pressure through damping hole 8 oil sump tanks 1, steadily descends.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model; the technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
