Description

Technical Field

[0001] The utility model relates to the technical field of mechanical seals, in particular to a compact buffer air cooling system for double-end surface mechanical seals. Background Art

[0002] Double-end seals generally use an external gas-pressurized buffer tank to provide clean buffer for the isolation fluid sealing cavity. The pressure of the buffer is kept higher than the pressure of the sealing cavity so that the buffer is located between the two sets of seals. The buffer is output from the tank using an internal circulation device and returned to the sealing cavity after heat dissipation.

[0003] Most current buffer cooling systems use liquid cooling, which has the following disadvantages: (1) If there is no coolant or the working environment is not suitable for liquid cooling, the buffer cannot be cooled; (2) If air cooling is used, heat sinks need to be installed. If only natural wind is relied on, the heat dissipation effect is still poor; therefore, if the heat dissipation effect is to be improved, the size of the heat sink needs to be increased, which will increase the volume of the storage tank.

[0007] Preferably, one side of the lower end of the upper liquid storage tank and one side of the upper end of the lower liquid storage tank are both provided with bayonet openings, and the upper and lower sides of the two cover shells are connected with buckles, and the upper and lower ends of the cover shells are snap-connected to the bayonet openings of the upper liquid storage tank and the lower liquid storage tank through the buckles.

[0008] Preferably, mounting ears are connected to both sides of the cover shell, and screw holes are provided on the mounting ears. After the two cover shells are closed, the mounting ears of the two cover shells overlap and are connected by bolts.

[0009] Preferably, a slot is provided at the lower portion of the cover shell, and an electrical connector is provided in the slot, wherein an induced draft fan in one cover shell is electrically connected to the electrical connector in the cover shell through a wire, and an exhaust fan in another cover shell is electrically connected to the electrical connector in the cover shell through a wire.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The buffer in the sealed cavity enters the upper liquid storage tank through the liquid inlet pipe, and enters the lower liquid storage tank through the heat dissipation pipe. When passing through the heat dissipation pipe, the heat in the buffer is dissipated through the heat dissipation fins. The buffer in the lower liquid storage tank then enters the sealed cavity through the liquid outlet pipe, thereby realizing the recycling of the buffer.

[0014] In order to improve the heat dissipation effect, a cover is installed on the periphery of the heat dissipation pipe and the heat dissipation fins. The induced fan blows air to the heat dissipation fins, and the exhaust fan quickly discharges the heat, thereby achieving strong air convection and improving the heat dissipation effect. There is no need to increase the size of the heat dissipation fins and the heat dissipation pipe, thereby reducing the overall size of the storage tank. BRIEF DESCRIPTION OF THE DRAWINGS
