Description
Technical Field
The utility model relates to a double suction pump is with exempting from water forced air cooling heat exchanger cooling mechanical seal mechanism mode specifically is to cool off back cooling heat exchanger water and then cooling mechanical seal water through the vortex tube to compressed air.
Background
With the increase of the use places of the double suction pump, particularly the places for conveying high-temperature medium water are increased. When delivering high-temperature medium water, the mechanical seal is generally washed by hot water, so that the mechanical seal cannot be cooled. The conventional solution method is to use a heat exchanger to cool the mechanical seal, but the conventional heat exchanger needs to be externally connected with cooling water, and a large amount of washing water is needed in the scheme, so that the water resource is greatly wasted. The condition of no external cooling water exists in individual sites, so that the mechanical seal cannot be effectively cooled. It is therefore desirable to improve the cooling of mechanical seals for double suction pumps.
Disclosure of Invention
The utility model discloses a solve the double entry pump mechanical seal cooling problem of carrying the high temperature medium, effectively solve high temperature medium water and just avoid wasting water resources to mechanical seal cooling problem. The utility model discloses a two suction pump are with exempting from water forced air cooling heat exchanger cooling mechanical seal mechanism, including two suction pumps, a serial communication port, main shaft at two suction pumps is the extension axle, an outside end at the extension axle is provided with the fan blade casing, install the fan blade in the fan blade casing, the fan blade is fixed at the extension axle by lock nut and stretches out the end, be provided with air inlet and gas outlet on the fan blade casing, the gas outlet is connected with the vortex tube intake pipe, vortex tube intake-tube connection vortex tube, the air inlet of heat exchanger is connected to the gas outlet of vortex tube, be provided with the gas outlet on the heat exchanger, the inlet tube is connected to the one end of the coil pipe in the heat exchanger, the mechanical seal delivery port is connected to the other end of inlet tube, the outlet pipe is connected to the other end of coil pipe in the heat exchanger, the mechanical seal water inlet is connected to the other end of outlet pipe. The water outlet pipe connected with the coil pipe in the heat exchanger is provided with two branches which are respectively connected with the mechanical seal water inlets at two ends of the double-suction pump. The utility model has the advantages that simple structure, the cooperation heat exchanger uses, and occupation space is little, and is reliable and stable, easily installation, moving part are only the fan blade, and no electric device does not have other wastes (the water-cooling can waste a large amount of water resources). Is a structure which is convenient to add and has good refrigeration effect.

Detailed Description
The present invention will be described in detail with reference to the following examples and drawings,
the cooling mechanical sealing mechanism of the water-free air-cooled heat exchanger for the double suction pump comprises a double suction pump 1 and is characterized in that a spindle 11 of the double suction pump is a lengthened shaft, a fan blade shell 8 is arranged at one outer side end of the lengthened shaft, a fan blade 9 is installed in the fan blade shell and fixed at the extending end of the lengthened shaft through a locking nut 10, an air inlet and an air outlet are formed in the fan blade shell, the air outlet is connected with a vortex tube air inlet pipe 7, the vortex tube air inlet pipe is connected with a vortex tube 6, the air outlet of the vortex tube is connected with the air inlet of a heat exchanger 4, an air outlet 5 is formed in the heat exchanger, one end of a coil pipe in the heat exchanger is connected with a water inlet pipe 2, the other end of the water inlet pipe is connected with a mechanical sealing water outlet 12, the other end of the coil pipe in the heat exchanger is connected with a water outlet pipe 3, and the other end of the water outlet pipe is connected with a mechanical sealing water inlet 13. The water outlet pipe connected with the coil pipe in the heat exchanger is provided with two branches which are respectively connected with the mechanical seal water inlets at two ends of the double-suction pump.
The method comprises the following specific implementation steps: the fan blades are fixed to the lengthened shaft through locking nuts and rotate synchronously with the main shaft, air is sucked in through the end face of a fan blade shell, is extruded to an air outlet through the rotation of the fan blades, compressed air enters the vortex tube through the air inlet pipe of the vortex tube, the vortex tube is used for manufacturing cold air after working, the cold air enters the inlet of the heat exchanger through the vortex tube and is connected with the heat exchanger pipe, and the cold air is discharged through the air outlet of the heat exchanger after working. The hot water of the double suction pump is pumped out by the double suction pump and enters the heat exchanger through the heat exchanger pipe, and the hot water is cooled in the heat exchanger and then enters the mechanical seal cavity through the cold water of the heat exchanger and the mechanical seal cavity pipe to cool the mechanical seal.
The specific detail power source comes from the extension shaft, and the fan blade does synchronous revolution along with the main shaft, does not have the rotation deviation, and the water pump is changeing, and the fan blade just can rotate simultaneously, guarantees the synchronism, guarantees that the water pump can carry air conditioning cooling for the heat exchanger once running. Compressed air enters the vortex tube through the air inlet pipe of the vortex tube by the fan blades, the compressed air enters the vortex tube, the compressed air is converted into low-temperature cold air flow through the self performance of the vortex tube to cool local hot spots, the lowest temperature of the generated air flow can reach-40 ℃, the low-temperature cold air flow is short-circuited to one end of the heat exchanger, the cold air is discharged from an air outlet of the heat exchanger after working and cooling in the heat exchanger, hot water in a cooling mechanical seal cavity is pressed out by a water pump to enter the heat exchanger, the hot water is cooled by the working of the heat exchanger, and the hot water returns to the mechanical seal cavity to cool the mechanical seal.
The utility model has the advantages that simple structure, the cooperation heat exchanger uses, and occupation space is little, and is reliable and stable, easily installation, moving part only are the fan blade, and no electric device does not have other wastes (water-cooling can waste a large amount of water resources). Is a structure which is convenient to install and has good refrigeration effect.
