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...

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...
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 ...
Heat pump is a device that transfers heat energy from a low-level heat source to a high-level heat source. It is a energy-saving high-efficiency device that makes full use of low-grade heat energy. It is a new energy technology that attracts much attention all over the world. As we all know, heat can be transferred spontaneously from high-temperature objects to low-temperature objects, but not in ...
Maybe you are not heard of Shinhoo, and maybe you haven’t seen our pumps in your daily life, but our pumps are closely related to your daily life. Let us see the following photos: The core of household water heater, gas wall stove, floor heating and so on is our water pump. The principle is to drive water circulation through the impeller rotation, so that the hot water can always flow in the pipe ...
Ⅰ.Noise Cause 1：Impurities that entering the gap of rotating parts makes friction noise. Solutions: 1. Disassemble the pump and take out impurities in the runner. 2. Use water softener to reduce scale formation. 3. Use a filter net to keep the water in the pipeline clean. Cause 2: Shaft abrasion caused by scale and by grinding due to lack of water. Solutions: 1. Change the rotor and impeller. 2. U...
