Problems solved by technology
During the test, the water tank will be required to be lifted from the ground to a 3.2m platform and then dropped from the platform to the ground. It is not easy to lift such a large-span and heavy-weight water tank from the ground to the plane, and It is required that during the lifting process, the water tank is not allowed to shift, otherwise the water tank will be stuck by the track, unable to continue to lift, and even cause damage to the water tan

Embodiment Construction
[0019] Such as figure 1 As shown, the hydraulic station system of the present invention includes an oil tank 1 and four jacking hydraulic oil circuits
[0020] 201, 202, 203, 204 and a bolt hydraulic oil circuit 300.
[0021] Each jacking hydraulic oil circuit includes a duplex pump 8 driven by a speed regulating motor 7 , a two-position three-way solenoid valve 32 , a proportional overflow valve 12 and a first one-way valve 111 .
[0022] Wherein, the oil inlet of the duplex pump 8 is connected to the oil tank 1 through the first ball valve 151, and the oil outlet of the main oil pump of the duplex pump 8 is connected to the first oil port of the two-position three-way solenoid valve 32, and the two-position three-way The second oil port of the solenoid valve 32 is connected to the oil inlet port of the first one-way valve 111 .
[0023] The oil outlet of the auxiliary oil pump of the double pump 8 is directly connected to the oil inlet of the first one-way valve 111, and t...

The invention discloses a hydraulic station system. The hydraulic station system comprises an oil tank and an ejecting hydraulic oil channel, wherein the ejecting hydraulic oil channel comprises a double pump driven by an adjustable-speed motor, a two-position three-way solenoid valve, a proportional overflow valve and a first non-return valve; an oil inlet of the double pump is connected to the oil tank; an oil outlet of a main oil pump of the double pump is connected to a first oil port of the two-position three-way solenoid valve; a second oil port of the two-position three-way solenoid valve is connected to the oil inlet of the first non-return valve; the oil outlet of a secondary oil pump of the double pump is directly connected to the oil inlet of the first non-return valve; the oil outlet of the first non-return valve is connected to the oil inlet of the proportional overflow valve and a first system outlet. The hydraulic station system has the advantage of being capable of accurately controlling the speed and pressure of hydraulic oil entering an oil cylinder.
Description
technical field [0001] The invention relates to hydraulic equipment, in particular to a hydraulic station system. Background technique [0002] In the impeller dynamic test, one of the important test items is to place the guide vane in a super-large water tank for testing. This super-large water tank is 3 meters wide and 6 meters long, and weighs 132 tons when it is full of water. During the test, the water tank will be required to be lifted from the ground to a 3.2m platform and then dropped from the platform to the ground. It is not easy to lift such a large-span and heavy-weight water tank from the ground to the plane, and It is required that during the lifting process, the water tank is not allowed to shift, otherwise the water tank will be stuck by the track, unable to continue to lift, and even cause damage to the water tank. [0003] In order to realize precise control of the lifting process of super-large and heavy equipment such as water tanks, the applicant thoug...
