Failure three gauge water pressure but still reasons: 1. too much resistance outlet pipe 3. 2. Turn right direction outlet pipe valve is not open impeller clogged 4. Solution: 1. Check or cord short pipe 2. Check Motor two intermodulation 3. Open the outlet valve 4. remove dirt impeller failure to reach the design flow rate of four reasons: 1. There are air intake 2. Due to lower the water level inside the submerged deep enough impeller blockage 3. 4. rotor portion severe wear solutions: 1. Check the leak site and the exclusion 2. extend deeper water pipe flooded the depth 3. Remove and drops in addition to foreign bodies 4. Replace the seal ring is mounted using the Edit installation This pump is installed in addition to satisfying the general installation. Technical requirements Jiangxi mining wear multi-stage pump, it should note the following: 1, when a combination of motor and pump installation, should the pump coupling end of the axially outer pull out, and then leave 3-5mm end clearance values wear multi-stage pump prices in order to guarantee the value of the pump and motor axial gap between the two coupling. Note: Make sure the floor leveling, equipment level of good after grouting CAUTION: To make a successful installation wear multi-stage pump, the coupling adjustment must be correct, a flexible coupling can not compensate for any obvious imbalance. Imbalance may cause rapid wear, noise, vibration and damage to the equipment. Therefore, the coupling must be adjusted within the given limits. Caution: You must take measures to support the pump inlet and outlet, to prevent overloading the pump inlet 2, the centerline of the pump and motor shaft should be on the same horizontal line. 3, the pump can only afford their own internal forces, can not withstand any external force. md wear multi-stage pump, Bijie wear multi-stage pump, mine wear multi-stage pump is provided by Anguo City Pump Co., Ltd.
