I-1B series of thick pump is a single screw volume rotary pump, the pump using eccentric single-screw rotation within the double helix, so that the thick slurry along the spiral groove from the suction port to the discharge port, the pump delivery Features. Faults and Troubleshooting Reasons to troubleshoot 1. Difficult to start 1. The feed liquid is not filled in the pump chamber. Frictional resistance is large: 2. The packing gland is pressed too tightly. The friction torque between the shaft and packing is too large. 1. Use a pipe clamp to move the spindle pump shaft 3 to 6 turns: 2. Adjust the packing gland. 2. No liquid after starting 1. There is a lot of air inhaled: 2. The motor is not steering: 3. Fluid viscosity is too large. 1. Check suction level is too low suction pipe leaks 2. Connect any two-phase motor into the line: 3. dilute the feed solution. 3. The pump has a lot of vibration or noise 1. The motor is not the same as the pump shaft: 2. Air is sucked into the pump or there is a lot of air mixed with the material - 1. To re-adjust the concentricity: 2. Check the material level. Remove air from inhalation liquid. 4. During operation, the flow rate drops significantly 1. The bushing is worn and the clearance is increased: 2. The speed is reduced: 3. The gimbal shaft or stern shaft is damaged. Transmission failure: 4. Insufficient penetration of liquid into the suction pipe. Air into the pump ^ 1. Replace the bushing. If necessary, for the screw: 2. Check the power and motor: 3. Shutdown maintenance. Replace shaft 朕 shaft section or around the axis: 4. Off a small inhalation height. Once immersed into the depth of the inhalation of liquid air to exclude 5. Motor overload 1 head over the pump stroke too much: 2 liquid viscosity is too high: 3 voltage is too low 1. Minimize the pipe head Loss or replacement of high-lift pump. 2. Dilute the feed solution: 3. Check the cause. Increase the voltage to the specified value. 6. A large number of shaft seal packing leakage 1. Gland is too loose: 2. Packing wear: 3. Inverse position import and export. 1. Adjust the gland: 2. Replace the packing: 3. Take the middle flange port as suction port.
The history of stone carving begins with the origin of human art. It can be said that there is no art form that is more ancient than stone carving, and there is no art form that is more popular and lasting. The history of stone carving can be traced back to the middle of the Paleolithic Age, which is about 120000 years ago. Since then, stone carvings have been handed down to this day.
