Haitan pump submersible pump safe and efficient use of five points Haitan pump submersible pump safe and efficient use of five points 1. When purchasing submersible pump should pay attention to its model, flow and head, such as the use of inappropriate specifications, will not be able to get enough water, can not play unit efficiency. In addition, we should also clarify the direction of rotation of the motor, some types of submersible pump forward and reverse can be water, but reverse the small amount of water, current, reverse will damage the motor windings. To prevent submersible pump leakage in the water when working under the accident caused by electric shock, leakage protection switch should be installed. 2. When installing submersible pump, the cable should be overhead, the power cord should not be too long Do not force the cable when the unit is launching, so as to avoid causing the power cord to break. Submersible pumps do not sink into the mud during work, otherwise it will lead to bad cooling and burn motor windings. Installation, the insulation resistance of the motor should not be less than 0.5 megohms; 13 kW motor can be started directly below 13 kilowatts should be used to start the compensator. 3. Try to avoid starting the low-voltage power supply voltage and rated voltage can not be a difference of 10%, the voltage is too high will cause the motor overheating and burn the winding, the voltage is too low, the motor speed drops, if less than 70% of rated speed, start the centrifugal switch Will be closed, resulting in a long time to start the winding energized and even burn the windings and capacitors. Do not switch the motor on and off frequently. This is because the pump will run back when it stops. If it is turned on immediately, the motor will start to load, causing the starting current to be too large to burn the winding. 4. Do not idle and overload operation Do not allow the pump long-term overload operation, do not pumping large amounts of water, dehydration pump operation time should not be too long, so as not to overheat and burn the motor. During the operation of the unit, the operator must keep an eye on whether the working voltage and current are within the values ​​specified on the nameplate. If not, the motor should be stopped to find out the cause and solve the problem. 5. Inspection usually peacetime inspection motor, found under the crack, rubber seal ring damage or failure, etc., should be promptly replaced or repaired to prevent water penetration into the machine.
Smart Lights
Our Smart Light has a longer lifespan and more complete functions. The life of the smart light is determined by the light decay, and there are four main reasons that affect the luminous decay. 1. The raw materials of the product. The less the impurities, the less the heat dissipation. All our products are made of original brass, and the quality of the products is strictly controlled from the raw materials. Second, the heat dissipation structure of the product. We have more than ten years of work experience in structure research and development personnel. Each product has undergone heat dissipation design, heat dissipation simulation, and heat dissipation experiment to ensure the best heat conduction and heat dissipation of the product. Third, the design of the power supply, the higher the efficiency of the power supply, the better the heat dissipation. Our electronic engineers with more than 15 years of work experience adopt imported chip solutions and use the smallest space to make the power supply with the highest efficiency and the lowest temperature rise. Fourth, for LEDs, we purchase light sources from American CREE or Japan's Citizen to minimize light decay.
Smart lights is available in wattage dimming, romotely controll, module replaceable. More importantly, we are professional in OEM and ODM. We are a brass landscape lights factory integrating R&D, design and manufacturing. Please click on the product to learn more about our products.
