Problems solved by technology
The first oil pump and the second oil pump of the existing hydraulic oil station share a relief valve. If the relief valve is jammed or malfunctions, it cannot be cleaned and replaced online. At this time, even if the first oil pump and the second oil pump are started at the same time, the oil Station can not work normally, therefore, those skilled in the art provide a fan hydraulic station double overflow valve block reconstruction device, in order to solve the problems raised in the above background technology

The invention discloses a device for reconstructing double overflow valve blocks of a hydraulic station of a fan. The device for reconstructing the double overflow valve blocks of the hydraulic station of the fan comprises an oil tank body, wherein a first motor convenient to provide power is fixedly arranged at the upper end of the oil tank body; a second motor is fixedly arranged at a position,located on the same horizontal line of the first motor, at the upper end of the oil tank body; and a first oil pump is fixedly connected to one end of the first motor. According to the device for reconstructing the double overflow valve blocks of the hydraulic station of the fan provided by the invention, a valve block on an outlet of an oil pump is redesigned, a hydraulic oil station is double-overflow reconstructed, and each oil circuit is provided with an independent overflow valve and a stop valve; when a first overflow valve or a first one-way valve is failed, a second oil pump is started, then a first oil pump stops working, and a first stop valve is closed, so that the first overflow valve or the first one-way valve of a main oil circuit of the first oil valve can be cleaned and replaced; and when a second overflow valve or a second one-way valve is failed, the same method is utilized for handling the situation. With the design, the operating reliability of an oil station and the fan are improved, and working personnel can conveniently operate the device.
Description
technical field [0001] The invention relates to the technical field of a fan hydraulic station, in particular to a double overflow valve block transformation device for a fan hydraulic station. Background technique [0002] The hydraulic oil station of the fan is an important part of the fan adjustment device. The reliability is directly related to the flexibility, accuracy and reliability of the blade adjustment device. In order to ensure the long-life and reliable operation of the fan. The first oil pump and the second oil pump of the existing hydraulic oil station share a relief valve. If the relief valve is jammed or malfunctions, it cannot be cleaned and replaced online. At this time, even if the first oil pump and the second oil pump are started at the same time, the oil Station can not work normally, therefore, those skilled in the art provide a fan hydraulic station double relief valve block transformation device to solve the problems raised in the background technol...
