Underground drainage equipment, emergency drainage equipment, climbing edge technology

Changsha Science and Technology Development Co., Ltd. Pan was established in 2000 to automatically water supply equipment, stainless steel water tanks and water treatment equipment for the development, production body, has a long-term commitment to research and development of high-tech talent and an outstanding equipment installation works team, covering Hunan, Hubei, Jiangxi, Guangdong, Shanghai, so far, has successfully for more than one national key projects, well-known institutions, industrial enterprises, government office buildings, the province many well-known large-scale real estate House group, high-rise building, cigarette factory in Changsha multiple dormitories and other groups to solve the water supply and drainage is difficult. And it has won high praises from users, especially in recent years, the company launched a series of intelligent non-vacuum laminated (constant pressure) water supply equipment, the national five ministries and the key recommendation of the Ministry of Construction projects, represents the most advanced domestic level, triggering major reforms in the field of domestic water supply, which not only provides an efficient water supply areas, energy-saving, pollution-free new ideas, and the green, clean and efficient to dissolve into millions of households, really completely solved the problem of water supply industry for many years the traditional water supply secondary pollution. How to extend the life of the deep well pump domestic water supply equipment is well known as a core component of the pump water supply equipment, household water supply equipment is the key to whether the normal operation, in addition to the principle of centrifugal related understanding, we more important is how to related to our pump maintenance to extend the life of the pump, the following detail from the following points should be noted that what matters to extend pump life. First, before starting to prepare: 1, the test motor rotation is correct, from the top of the pump motor to see the clockwise rotation, test time should be short in order to avoid the mechanical seal dry wear. 2, open the exhaust valve so that the liquid fills the pump, to be filled close the exhaust valve. 3, check all parts are normal. 4, hand plate moving pump lubricating fluid into the mechanical seal face. 5, the high temperature should be run warm-up, a heating rate of 50 ℃ / h, in order to ensure uniform heating ministries. Second, start: 1, fully open the inlet valve. 2. Close the discharge pipe valve. 3, the starter motor, observe the pump is running correctly. 4, adjusting the outlet valve opening to the required conditions, such as the user is equipped with a flow meter or pressure gauge at the pump outlet should be made by adjusting the pump outlet valve opening operation at the rated point performance parameters listed in the table, such as a user at the pump outlet when not loaded flow meter or gauge, should start by adjusting the outlet valve degrees; measuring pump motor current, the motor runs at the rated current, otherwise it will cause pump overload (ie high current operation, to make motor burned out) just tune outlet valve opening big and small and pipeline related conditions. 5. Check the seal leaks, mechanical seal leakage should be less than 3 drops / minute of normal time. 6, check the motor, the bearing temperature rise ≤70 ℃. Third, stop:
