The water pump does not run after power supply on, it is called "locking", which is the most common situation of wall-hung boiler water pump. It often occurs after the wall-hung boiler has not been running for a long time. 1. Locate a large screw on the top of the water pump and use a large "one" screw to loosen it. Then use a suitable screw to loosen the inner shaft slowly. After you feel the jam...
After a non-heating season, the heating pipes of wall-hung boilers are left unused which is likely to produce impurities after rust and microbial precipitation. Water pump is a precision component inside the wall-hung boiler. These impurities can easily hinder the operation of the water pump, causing it to jam, increase noise, or even damage it. The ideal solution is to release and clean the water...

There are several reasons that cause water circulator pump do not start. 1. Problems with power supply: You should check the plug and socket and the cable. Check circuit breaker in electrical panel. 2. Capacitor not working: Needs a new capacitor, not expensive. 3. Air pressure in water pressure tank too high: Reset air pressure in pressure tank. 4. ...
There are mainly four reasons that cause canned motor pump can not pump water 1. Water or air leakage in the pipeline: The nut may not be tightened tightly during installation. If the leakage is not serious, apply cement or cement slurry mixed with asphalt oil on the leaking or leaking place. Serious water leakage must be re-disassembled. 2. The water circulator...
High pressure centrifugal pump working principle :Relying on the action of the rotating impeller on the liquid to transfer the mechanical energy of the prime mover to the liquid. Due to the action of the liquid flowing from the impeller inlet to the outlet, its speed and pressure energy are both increased, and the liquid removed by the impeller passes through In the press-out chamber, most of the ...
The impeller is an important accessory of the canned pump, and its shape, size, processing technology, etc. have a decisive influence on the performance of the water circulator pump. The function of the impeller is to transfer the energy input from the prime mover to the liquid. There are three main structural forms of water pump impellers: those with front and rear cover plates are called closed ...
