What tools are needed to replace the water seal for the air conditioning pump? What's the name?
Here I introduce the replacement of mechanical seals technical points:Mechanical seal principleThe seal is defined by at least a pair of end faces perpendicular to the axis of rotation of the fluid pressure and the elasticity of compensation organizations (or force) the role of the device and auxiliary seal with maintaining relative sliding postmerger and constitutes to prevent fluid leakage. The main parts of mechanical seals are as follows: A. main seals: moving ring and stationary ring. B. auxiliary seals: seals. C. press: spring.
Four. Inspection of mechanical seal before installationBefore assembling the mechanical seal, the moving ring, the stationary ring, the shaft sleeve and other parts should be thoroughly cleaned. Key examination:1. whether there is any scratch, crack and other defects on the surface of the dynamic ring, these defects will cause serious leakage of the mechanical seal.2. check whether the static ring seat affects the sealing defects. Such as static and dynamic ring seat and dynamic ring seal apron, with the presence of defects such as scars.3. check whether the mechanical seal spring is damaged or deformed and whether the coefficient of rigidity changes.4. check the sealing sleeve whether there is burr, groove mark and other defects.5. sweep check all seal aprons whether there are cracks, holes and other defects, measuring whether the rubber ring diameter in the range of work.6. pump mechanism of mechanical seal, but also to check whether the spiral of the spiral pump cracks, broken wires and other defects.
Two. Water pump mechanical seal damage, those effects can cause leakage, protection alarm, water pump can not work properly, serious water pump motor, burning the motorThree. How to remove mechanical seals?1., maintenance pumps will be power outages and listing, in the water pump from the sump hanging out to clean.2. make a mark between the pump base and the oil chamber to make it easy to install and remove the bottom seat (the fixed base is three inner six angle bolts)3. remove the fixed bolts from the impeller and remove the impeller with the pull codes.The lower end of the 4. oil cavity is provided with three inner six angle bolts, and the oil cavity is removed and cleaned, and the original mechanical seal static ring is disassembled.5. to see the water leakage protection points clean, measuring leakage protection point and pump casing resistance (resistance value is close to 500 billion Ou)
Replace mechanical seal of water pumpIn the water supply and drainage system and air conditioning system, water pump occupies an important position. The maintenance of water pumps has become a skill we must master.
