The causes for the leakage of high temperature heat pump and the emergency response method
the use of high temperature heat pump is closely connected with users daily use standard operation. In addition, the understanding of high temperature heat pump daily daily troubleshooting is extremely important. Like water pump leakage, we should find the right solution, the editors will brief analysis of the causes for the leakage of high temperature heat pump and the emergency treatment method.
1, the working conditions of construction machinery. Easy on bakelite seals and bushing end face form uneven wear. Spring water for a long time, easy to rust, reduces elasticity and cause leakage.
2. In the winter, if you don't forget to water or water clean, and the temperature is too high, after the condensation water vapour in the cooling system will freeze, which may lead to the pump body freeze and burst, causing leakage.
3, installing a heat pump, not the water seal seat ring components installed, resulting in continuous leakage of pump. Because the inspection hole corresponding to the pump shaft with a manger ( Shaking) Water ring, so when the water seal leakage in the cooling water pump in water retaining ring was thrown and observation hole dripping from the water pump. Axis. To prevent the cooling water flow into the bearing, and make it smooth. In addition, the replacement of water ring, please take care not to eliminate between pump body and pump cover sealing, the sealing not well sealed, and can also lead to pump leaking.
4, the machine is old, and the water seal of the internal parts wear and tear, rust and aging is the leading cause of pump leaking in the factors. Park construction machinery for a long time, because of no cooling water, the engine will therefore bakelite seal for drying and shrinkage deformation. Although bakelite seal swells when adding water, but was unable to fully recover, this leads to a small amount of leakage. In addition, the pump for new equipment, bakelite seals and cast iron liner has not been fully wear and tear, this will also bring a small amount of water leakage in the pump.high temperature heat water pump leak emergency treatment methods:
if it is found that det pump leakage, then please do not stop immediately. You should maintain a low speed, and to the internal water cooling system ( Note: open the cover, water injection should be above the water cover) Cover to prevent the combustion of water vapor) Slowly moving, cooling device, for short periods of time, and then drive to the nearby shelter for cleaning. If the pump shell burst and leakage, or the internal parts of the pump damage and loss of pumping function, can replace the relevant appropriate parts to eliminate the fault.
if the pump damage and no maintenance conditions on the way, it can be connected directly to the pump inlet pipe and outlet pipe, in order to make full use of the natural circulation of hot and cold water effect to temporarily keep blasting machine in the room temperature may be used as a container or bucket, inner tube to be firmly fixed, and then from the container to pull out two rubber hose, a water inlet connected to the initiator, the other connected to the outlet of the initiator. The other two tube inserted into the container and firmly fixed at the end of the hose. If it is just crack leakage of the pump casing can eliminate cracks, and then use glue to repair. For an emergency, can add the egg white cement mixing to form clumps, condensation can be used after fracture.
during the engineering mechanical drive or work, pump leakage water seal is also common. As long as the water valve without damage or swelling deformation, there is not lack of water seal spring force, also can perform other emergency treatment. Emergency handling the specific method is: if the water water pump water seal slight leakage due to poor sealing, but wear is not serious, could be a piece of glass or tablet with emery cloth, and then polished 020 - The sealing surface. In turn, you can also use the water seal. However, attention should be paid to the surface of the water seal and pump body contact surface grinding should be conducted to ensure that its sealing function.
