1, water pump leaking reason
(1) installation of pumps, water seal seat assembly is not installed in place, causing the pump to continue leaking. And view the shaft
of the hole corresponding to the block (Lut) hydrosphere, and when the water seal leakage, cooling water along the shaft in case of
retaining ring from the pump manhole thrown out and Dettol, which prevents lubrication cooling water flows into the bearing damage. In
addition, replace the retaining ring, do not pay attention to clear between the pump and pump cover can not be a good combination and
sealing will cause the pump leaking.
â'µ old machine, water seal, mechanical wear and tear, corrosion and aging failure, pump leaking reason. When long-term parking of
construction machinery, due to engine cooling water, resulting in bakelite gasket dry, shrinkage and deformation; Bakelite seal swell,
but not full restitution after adding water, is bound to cause a small amount of leakage. In addition, the newly installed pump, the the
bakelite seal and cast iron bushing is not yet fully running good, will also lead to pump a small amount of leakage.
â'¶ construction machinery harsh working environment, likely to cause uneven wear in of bakelite seal and bushing end; spring soak in
water for a long time, easily corroded, stretch down, can also cause leaks.
â'· forget to water or water net, and the water temperature after the condensation of water vapor cooling system within the ice, may have
resulted in the pumps pump was the cracking, resulting in leaking in winter.
2, the emergency measures
If you find that are operating the engine water pump leaks, shall immediately stop the work should be to keep it at the lowest stable
speed, side and waterside water to the cooling system (Note: Open the filler cap, should be put on the top covering to prevent steam
burns) smoke, engine cooling, and a short period of time, slow driving, reaching near the shelter and then excluded. If you suddenly
encountered a pump shell rupture and leakage, or water pump mechanical damage lost pumping effect, may, at their discretion, replace
parts, troubleshooting.
Pump damage is very serious, the way they did not repair the condition, can pump into the outlet pipe directly connected to the
temporary engine to maintain normal temperature; to take advantage of the natural cycle of the role of hot and cold water or use an
inner tube or bucket as container, firmly fixed, and then leads to two hose from the container, the one connected to the engine intake,
the second pick in the engine outlet, the other end of the two tubes are inserted into the container and should be fixed firmly hose.
If the pump shell cracks and leakage, and can handle clean cracks, and then stick with adhesive to fill. Emergency, the available egg
plus cement mixture into the molasses applied in the cracks upon solidification a few minutes.
Driving or operating process of construction machinery, water pump water seal leakage is a frequent occurrence. As long as the rejection
of the hydrosphere is damaged or swelling deformation, the spring force of the water seal or break, such as failure, can deal with
emergency. The specific practices of the emergency response: If the water pump water seal minor leaks due to poor sealing, but the wear
and tear is not too serious, in glass or flat capped with an emery cloth, a water seal sealing plane grinding flat can be; also bakelite
water seal flip before use. But should be aware of grinding, the contact surface of the water, cover and water pump body should be to
ensure that the sealing performance.
