DETAILED DESCRIPTION

[0023] In order to make the content of the utility model more easily and clearly understood, the utility model will be further explained in detail below according to the specific embodiments and in conjunction with the drawings.

[0024] Figure 1 The structure diagram of the pump seal cooling device provided by the embodiments of the present application is shown. The device comprises a pump seal assembly, a seal water tank and heat dissipation fins. The seal water of the pump seal assembly is cooled by the independent seal water tank, avoiding the pollution of a single pump seal affecting all the seal water.

[0025] Specifically, a first water inlet is formed in the upper end of the pump seal assembly, and a first water outlet is formed in the lower end of the pump seal assembly.

[0026] The seal water tank is fixedly installed on the pump seal assembly by a mounting bracket. A second water inlet is formed in the upper part of the side wall of the seal water tank, and a second water outlet is formed in the bottom of the seal water tank. The second water outlet of the seal water tank is communicated with the first water inlet of the pump seal assembly through a first pipeline. The first water outlet of the pump seal assembly is communicated with the second water inlet of the seal water tank through a second pipeline. A valve for controlling the opening and closing of the first pipeline is arranged on the first pipeline.

[0027] When the seal works, heat is generated between the dynamic ring and the static ring through friction, and the pump exchanges heat with the seal water, so that the temperature and pressure of the seal water are increased, and then the seal water in the pump enters the seal water tank through the second pipeline. After that, the seal water enters the first pipeline, and then returns to the pump seal assembly after cooling, and continuously circulates.

[0028] Preferably, referring to Figure 1 Heat dissipation fins are fixedly arranged on the outside of the first pipeline. After the seal water enters the seal water tank and then enters the first pipeline and flows along the first pipeline, the heat dissipation fins can cool the seal water in the first pipeline, so that the seal water is cooled and then returns to the pump seal assembly, thereby absorbing the heat generated during the operation of the pump, and ensuring the cooling effect of the pump.

[0029] An opening is arranged on the top of the seal water tank, and a cover for closing the opening is detachably installed at the opening. When it is necessary to add seal water to the seal water tank, the operator can open the cover and add seal water to the seal water tank through the opening.

[0030] A blowdown port is also formed in the bottom of the seal water tank, and a blowdown pipeline is connected to the blowdown port, and a valve for controlling the opening and closing of the blowdown pipeline is arranged on the blowdown pipeline.

[0031] In the embodiment, the side wall of the machine seal water tank is transparent, so that the operator can directly observe the liquid level and turbidity of the machine seal water in the machine seal water tank. If the machine seal water in the machine seal water tank is insufficient, the operator can timely add machine seal water into the machine seal water tank. If the machine seal water is too turbid, the turbid machine seal water can be discharged through the blowdown port and blowdown pipeline, and then machine seal water is added into the machine seal water tank.

[0032] It should be noted that the machine seal water is high-purity water.

[0033] In another embodiment, the machine seal water tank is not transparent, but an observation window for observing the inside of the machine seal water tank is arranged on the side wall of the machine seal water tank. The observation window extends along the height direction of the machine seal water tank, and the upper end of the observation window extends to the top of the machine seal water tank, and the lower end of the observation window extends to the bottom of the machine seal water tank. The operator can observe the liquid level and turbidity of the machine seal water in the machine seal water tank through the observation window.

[0034] Therefore, compared with the whole production line machine seal water system, the technical scheme provided by the present application does not need to design the whole production line machine seal water system, and does not need to design and purchase large machine seal water tanks and circulating cooling pools, thereby saving the design cost and the cost of purchasing materials. At the same time, the separate machine seal water cooling device avoids the pollution of a single pump machine seal to all machine seal water.

[0035] In addition to the above embodiments, the utility model can also have other implementation manners; any technical scheme formed by equivalent replacement or equivalent transformation falls within the protection scope required by the utility model.
