No. Solar energy refers to the energy of thermal radiation from the sun, which is mainly expressed in the form of solar rays. It is generally used to generate electricity or provide energy for water heaters. There are two conditions for installing solar energy. First, solar power should be close to the water pipe to facilitate solar water supply. Second, solar energy should be placed in a place where it can be directly illuminated by the sun and should not be used. be blocked by other objects. Therefore, solar energy can only meet the usage conditions if it is close to tap water and cannot be placed anywhere. With the decline of fossil fuels, solar energy has become a significant part of human energy consumption and continues to grow.
Water outlet.
It is simpler to insertInstall the water outlet circuit breaker on the hot water outlet pipe. As long as the hot water outlet pipe is closed, the water circuit breaker will operate. If installed on the tap water supply pipe, in addition to being able to cut off the power supply when using hot water, the power supply will also be cut off when filling the water heater with tap water, which is not necessary for actual use.
So-called water outlet cut-off devices for electric water heaters are "custom-made" by manufacturers for consumers who do not understand electricity. If it is safe to cut off the water outlet and electricity, then the instantaneous electric water heater factories have closed down. Many devices that require electricity to operate are also unusable.
Additional information:
As for the contact assistant, its technical skills mainly include: gap size, contact surface quality and spring tension.
(1) The size of the contact gap not only affects the closing angle, primary current and secondary high voltage, but also affects the ignition timing. Therefore, when adjusting the ignition timing, the contact gap must be adjusted. Its standard value is generally 0. 35 to 0.
(2) The contact area of the contact affects the contact resistance, primary current and secondary high voltage. Therefore, it is necessary to ensure that the mating surfaces of the contacts are parallel and account for more than 90% of the bonding area.
(3) The direct factor affecting spring tension is the thermal effect of the primary current. When the generator voltage is too high; the primary current is too large;the engine operates at low speed for a long time; the extra resistor is shorted and the secondary short of the ignition coil will anneal the spring and weaken the spring. tension.
