Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0025] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0026] Such as Figure 1-3 The installation position of the automatic trigger cooling branch circuit of the present invention shown in the present invention is surrounded by the overall structure of the motor, including the outer wall 1 of the motor, the inner wall 2 of the motor, the guide vane 4 and other components of the unit (the remote end of the motor, not shown in the figure). The first chamber 101 of the first chamber 101 is filled with the conveying medium flowing from the p...

The invention discloses a self-triggering cooling branch arranged in a wet-type motor. The interior of the motor is divided into a first cavity and a second cavity, and the second cavity is filled with cooling liquid; the self-triggering type cooling branch comprises a cooling liquid conveying pipeline arranged in the first cavity and a self-triggering switch arranged in the second cavity. A one-way valve A and a one-way valve B which are communicated with the second cavity are arranged at the two ends of the cooling liquid conveying pipeline, and the one-way valve A is a liquid inlet valve and controls cooling liquid to flow into the cooling liquid conveying pipeline from the second cavity. The one-way valve B is a liquid outlet valve; the self-triggering switch is arranged corresponding to the valve port position of the one-way valve A and used for opening the one-way valve A according to the temperature of the cooling liquid and controlling flowing of the cooling liquid between the cooling liquid conveying pipeline and the second cavity. The cooling branch can be automatically triggered according to the temperature of the cooling liquid at the position of the mechanical seal, when the temperature rises, the mechanical seal is further cooled, and the mechanical seal is prevented from losing efficacy.
Description
technical field [0001] The invention belongs to the field of fluid mechanical pumps, and in particular relates to a self-triggering cooling branch arranged in a wet motor. Background technique [0002] The high-power high-speed submersible pump unit is equipped with a wet motor to work, and a mechanical seal is used to separate the pump transmission medium from the cooling liquid in the wet motor cavity. Among them, the mechanical seal area is easy to accumulate heat, causing the temperature of the mechanical seal to be too high, causing the mechanical seal to fail, and causing the unit to not work normally. Contents of the invention [0003] Aiming at the problem that the temperature at the mechanical seal is prone to cooling failure and high temperature, the present invention proposes a self-triggering cooling branch arranged in the wet motor. [0004] Realize above-mentioned technical purpose, reach above-mentioned technical effect, the present invention realizes throu...
