Stainless steel water tank Features: 1, stable physical and chemical properties of stainless steel, for water pollution, ensure clean water quality. 2, high water tank strength, light weight, good clean, beautiful and elegant. 3, smooth surface appearance, easy to clean. 4, excellent corrosion resistance, good sealing performance. 5, large impact resistance, strong seismic performance. 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:
