Multi-stage pump failure and solution

Fault one: the pump is not suction gauge and vacuum gauge pointer violently beating

Reasons: 1. Insufficient filling perfusion 2. Pipeline and instrumentation joints leak 3. Suction too high

Solution: 1. Check whether the end of the valve leakage. Re-hire enough water 2. Tighten the leak 3. Lower water absorption height

Fault two: the pump does not absorb water vacuum table indicates a high degree of vacuum

Reason: 1. The end of the valve is not open or blocked 2. The suction pipe resistance is too large 3. The filter is clogged

Solution: 1.Check? Chase 2. replace the suction 3. clean the filter

Failure three: pressure gauge pressure but still no water

Reason: 1. The outlet pipe resistance is too large 2. The direction of rotation is wrong 3. The outlet pipe valve is not open 4. The impeller is clogged

Solution: 1. Check the hiss tick Oh trip 2. Check said 缁? Intermodulation of each other 3. Open the outlet valve 4. Clear the dirt inside the impeller

Fault four: reach the design flow

Reason: 1. There is air inhalation 2. As the water level decreases. Inundation depth is not enough 3. Impeller blockage of foreign body 4. Rotor part of the serious wear and tear

Solution: 1.Check Temple Temple 徊 lesson ⑴ ⑴ cowardly to extend the suction pipe to deepen the depth of flooding 3. Remove and remove foreign objects 4. Replace the seal ring

Fault five: pump power consumption is too large

Reason: 1. Packing pressed too tight. And fever 2. Flow too large 3. Swivel body and shell with friction 4. Pump bearing wear 5. Pump shaft bending

Solution: 1. Appropriate relaxation packing pressure 2. Off gate valve opening 3. Trim slewing body and shell position 4. Replace the bearing 5. Replace or correct

Failure six: Pump vibration increased

Reason: 1. Impeller partially blocked 2. Impeller damaged 3. Flow is too small 4. Pump shaft and motor are not the heart 5. Bearings damaged 6. Mixed with air. Cavitation occurs

Solution: 1. Removal and removal of foreign matter 2. Replace impeller 3. Slightly open the outlet valve 4. Fixed point to find 5. Change the suction bit. Improve the water absorption

Steel Structure

Tower Crane Steel Structure, regarded as the main parts of tower crane, refers to the tower crane jib, tower crane counter jib, tower head, tower crane Telescoping Cage, tower crane turning table,tower crane pull rod, tower crane Mast Section, tower crane Fixing Angle, ect. Steel Structure is made of steel, which fits the name.

Tower crane jib is a metal lattice structure of a normally triangular section, whose main mission is to provide the crane with the necessary radius or range. It is also called a jib. Like the mast, it usually has a modular structure to facilitate its transport.

The Anchorage Frame secures the tower crane mast to a structure or framework and provides stability when the tower crane is under load or experiencing wind forces.

The hook is the main load-bearing component that hauls loads. It is attached to a trolley that allows the hook to raise and lower, as well as move towards and away from the mast.
