do you know? Vacuum pump control cabinet common problems and solutions

What are the common problems of vacuum pump control cabinet? How to solve it? Xiaobian today to tell you the answer! You know? Vacuum pump control cabinet common problems and solutions 1, liquid level control reverse phenomenon: water supply (drainage) tank has been full (anhydrous), the control cabinet began to work, and no water (catchment full), control cabinet The opposite of stopping and using. Solution: Control the description of the float switch, which is normally closed for water supply, normally open drain, re-float the ball line. 2, the star delta decompression when starting the motor line then the wrong phenomenon: the motor starts normal, and go to run, the motor suddenly stopped or the air switch off. Solution: 1) Go to stop the motor in operation, check the wiring of the motor terminal to the terminal of the control cabinet according to the wiring diagram, and then readjust the wiring after checking. 2) Turn the air switch off during operation, and check whether the connecting copper pieces on the motor terminal are completely removed or the middle of the connecting cable is damaged or not. 3, auto-decompression starting torque is not enough phenomenon: auto decompression starter box at start-up, the motor starting torque enough not to move. Solution: 1) Check for missing phase. 2) Heavy-load start-up of the autotransformer 65% tap to 80% tap. (65% conventional) 4,15kw following a standby type with a direct start counter, failover. Phenomenon: Test failover, the main pump AC contactor coil arbitrarily removed a line, but can not automatically switch to the standby pump. Solution: The following 15kw with a spare control cabinet fault signal using the thermal relay normally open normally open contact for the fault signal. Solid test failover, the absence of thermal relays "97" and "98" caused a human failure test.

Welded Gabion Box

A gabion is a cage, cylinder, or box filled with rocks, concrete, or sometimes sand and soil for use in civil engineering, road building, military applications and landscaping.
Gabion baskets are wire containers made of hexagonal netting. The wire is double twisted and the mesh is reinforced by a wire border along the edges. The baskets are filled with stones and linked together to form a monolithic structure.
Gabion box, also known as a gabion basket, is a WIRE MESH container filled with stones or other hard materials. They are used in civil engineering projects to control erosion, stabilize soil, and create retaining walls.

Gabion mesh is the wire material used to make gabion boxes and baskets. It is typically made of heavy galvanized steel or coated with PVC to resist corrosion. The mesh is woven into a hexagonal pattern to provide strength and flexibility.

Gabion mesh is a type of wire mesh that is used to build structures like retaining walls, erosion control barriers, and other similar structures. It is typically made of steel wire that is woven into a mesh pattern, and then filled with rocks or other materials to create a strong, durable structure. The mesh is designed to be strong enough to hold the weight of the materials inside, while also being flexible enough to conform to different shapes and sizes. Gabion mesh is often used in civil engineering projects, landscaping, and other construction projects.
