Problems solved by technology

[0006] The purpose of the present invention is to overcome the defect of the existing single oil inlet hydraulic integrated valve, solve the lack of double oil inlet holes corresponding to the double large electric oil pump group, and need to indirectly connect the double large electric oil pump group and the hydraulic integrated valve by means of a three-way joint , the structure is complex, there are many oil pipe joints, the failure rate is high, there is a certain pressure loss after the hydraulic oil passes through the three-way joint, and the oil inlet hole of the hydraulic integrated valve is close to the fuel tank cover, the installation space is limited, and the installation and removal of the three-way joint is difficult. The technical problem is to provide a double oil inlet hydraulic integrated valve group and a double oil pump hydraulic station for a large filter press; Double oil pump hydraulic station for large filter presses, abbreviated due to the limited number of characters in the patent name

Embodiment 1

[0024] 1. Integrated hydraulic reversing valve (2. Integrated hydraulic reversing valve), 2. Integrated hydraulic relief valve (2. Integrated hydraulic reversing valve); The key points of the innovative overall implementation scheme are: the existing single oil inlet hydraulic integrated valve is improved into double oil inlet hydraulic integrated valve 1, including confluence hole 8 and oil return hole 9; The double hydraulic oil pipe 21 can be directly connected with the double large electric oil pump set 22 and the hydraulic integrated valve 1, and the tee joint is omitted; The specific implementation scheme is described in detail as follows.

[0025] The hydraulic integrated valve 1 is a cuboid hydraulic integrated valve 1, which is provided with oil inlet hole 6, various installation holes 7 (including integrated valve installation hole, one-way valve installation hole and overflow valve installation hole), confluence hole 8, oil return hole 9, overflow oil inlet hole 10, ove...

Embodiment 2

[0032] The utility model relates to a double oil pump type hydraulic station 25 for a large filter press (hereinafter referred to as the large hydraulic station), which uses the double oil inlet hydraulic integrated valve group 20 provided by the invention (hereinafter referred to as the hydraulic integrated valve group); The large hydraulic station 25 is mainly composed of double large electric oil pump set 22 (including high-power motor and gear oil pump), hydraulic oil tank 23, side chassis, hydraulic integrated valve set 20, air filter, oil return filter, liquid level gauge and hydraulic oil pipe 21; The hydraulic integrated valve group 20 includes hydraulic integrated valve 1, electro-hydraulic directional valve 2, hydraulic control one-way valve 3, electromagnetic overflow valve 4 and manual overflow valve 5, which has the functions of hydraulic oil reversing, overflow pressure stabilizing and check pressure maintaining; The double large hydraulic station 25 can automaticall...

Abstract

According to the double-oil-inlet type hydraulic pile-up valve group and the double-oil-pump type hydraulic station for the large filter press, the key points of the innovative scheme are that the hydraulic pile-up valve group comprises a hydraulic pile-up valve, an electro-hydraulic directional control valve, a hydraulic control one-way valve and an electromagnetic relief valve; the double-oil-inlet hydraulic pile-up valve is mainly characterized in that an existing single-oil-inlet hydraulic pile-up valve is improved into a double-oil-inlet hydraulic pile-up valve, so that double large electric oil pump sets and the hydraulic pile-up valve can be directly connected through double hydraulic oil pipes, and a three-way connector is omitted; the functions of hydraulic oil reversing, overflow pressure stabilizing and non-return pressure maintaining are achieved. The double-oil-pump type hydraulic station uses the hydraulic pile-up valve group, and solves the problems that a single-oil-inlet type hydraulic pile-up valve needs to be indirectly connected with a double-large electric oil pump group and the hydraulic pile-up valve by means of a three-way joint, the structure is complex, the number of oil pipe joints is large, the failure rate is high, and certain pressure loss exists after hydraulic oil is converged through the three-way joint; an oil inlet hole of the hydraulic pile-up valve is close to an oil tank cover, the installation space is limited, and the three-way connector is difficult to install and detach.
