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 ...
Circulating pumps are centrifugal pumps designed to generate a forced circulation in a closed system. Such us heating systems for hot water ,heat transfer systems, forced circulation boilers or reactor circuits ,and they are also used in open systems. The design of a circulating pump is often determined by the frequently high temperature of the fluid handled and the relatively low head which corre...
Recently, the rising oil price called for people’s attention. US President Joe Biden on Tuesday announced the imposition of an energy embargo on Russia, banning US imports of oil, liquified natural gas and coal from Russia over its ongoing military operations in Ukraine. Meanwhile, the European Union, which relies on Russia for some 40 percent of its natural gas supplies, announced earlier Tuesday...
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...
Ⅰ.Leakage Cause 1：The worn shaft causes the can damaged. Solutions:1.Test the motor resistance. If it is normal, replace the shielding cover- rotor assembly. 2.If the motor is burnt out, return it to the factory for maintenance Cause 2:During the maintenance of the water pump, the sealing gasket is poorly installed and deviated Solution:1.Reinstall the gasket. Ⅱ.Burning Cause 1: Burning caused by ...
