Small car core drilling rig

The Boyles C5/C5C surface core drilling rig is compact, yet powerful. Its compact design makes it easy to position and transport, even by helicopter. During helicopter transport, the rig is broken dow. [pdf]

Rock drill buffer piston failure case

In this study, the fracture of piston for rock drill produced from case hardening steel is investigated. In order to study the causes of the fracture, specimens prepared from the damaged pistons were subject. [pdf]

Screw air compressor host frequency conversion failure 004

Either an electrical problem, or the compressor has tripped on a safety device. Check supply power. Check for errors on display. Check emergency stop is out. Check and reset the overload relay. If it’s a new installation, check the phase sequence. Ambient temperature too high or not enough ventilation. [pdf]

FAQS about Screw air compressor host frequency conversion failure 004

Are ER CS screw compressors maintenance free?

ER CS Screw Compressor Maintenance and Repair:BITZER CS screw compressors do not have any internal valves and therefore are relatively maintenance free. However, the following p hecked as planned maintenance:4.1 Oil Supply:Annual o

How does a screw compressor work?

A screw compressor can run loaded ('pumping air') or unloaded ('idle'). The inlet/loading valve opens and closes according to air demand. The inlet valve is controlled by a solenoid valve that supplies control air to the inlet/loading valve. Check solenoid valve coil and solenoid valve operation.

How do I know if my rotary screw compressor is bad?

Check the voltage when the compressor is running. If the voltage drop significantly when the compressor starts/runs, you have a bad connection somewhere. Check all relays, fuses and electrical connections. Common rotary screw compressor problems and issues that have been reported. Get help with the most common problems for rotary screw compressors.

How do you operate a screw compressor?

w compressors operate in the correct rotation.Screw compressors can only be operated in one direction of rot ion; otherwise, substantial damage can occur.Connect a pressure gauge to the suction service valve and ensure the por

How do you connect a compressor to a roof ventilator?

Connect an exhaust duct from the compressor to the roof ventilator. Local exhaust ventilation to control temperature requires much lower air flow rate. If air is exhausted from the room, make-up air must enter the room. Local exhausting requires much less air flow. Connect an exhaust duct from the compressor to the roof ventilator.

Why is my air compressor flooded?

ing Start-up and then Returns to Normal Sound:This is an indication of liquid refriger t existing in the compressor before starting.Refrigerant returning to the compressor during off cycl ill also lead to a flooded start condition. Determine the source of refrigerant entering the compressor. Possible checks should include the expansion and
