Submersible pump installation safety inspection precautions

Submersible pump installation safety inspection precautions
First, the safe operation precautions
1. To participate in submersible pump installation or raise the operator, should be safety training, work focus and close cooperation.
2. When lifting (lifting) any equipment, sling, hanging chain and other hoisting tools should be strictly inspected to ensure compliance with requirements and undamaged to ensure personal and equipment safety.
3. Personnel operating electrical equipment must be trained to operate according to electrical safety practices.
4. In the submersible pump downhole components installed, raised wells must be cut off the power.
Second, the wellsite safety and security measures
1. Well site should be equipped with lightning protection device
2. Electrical equipment (control cabinet, transformer, junction box) should be provided around the fence, and with "high voltage danger" sign
3. Terrestrial cables shall be buried underground by means of ducts and provided with a cable duct or overhead to prevent damage.
4. Well site should be reliable grounding device, control cabinet, transformer, junction box, wellhead should be reliably grounded.
Third, the control cabinet (station) safety devices and precautions
Safety device
1). Control cabinet (station) are high pressure isolation zone
2) control cabinet (station) are grounding devices, and a grounding symbol
3) control cabinet (station) access and junction box are "high voltage danger" signs and text
2. Safety Precautions
1) The operator of the control cabinet (station) must be a trained electrical technician.
2) The operator must observe the electrical safety rules.
3) control cabinet (station) must be reliably grounded
4) must be blackout when troubleshooting.
Fourth, the transformer safety and precautions
1) alpine region with a transformer should be equipped with snow cover to prevent transformer short circuit.
2) The transformer is equipped with grounding device, which must be grounded reliably.
3) The operation of the tap changer must be operated during a power outage.
4) When observing the transformer, we must pay attention to safety and keep a certain distance with live parts. It is not advisable to observe on the high voltage side to avoid electric shock accident.
5) When monitoring the oil surface temperature, keep a certain distance. Observe the temperature from the exposed part of the thermometer. Do not touch the thermometer with your hands.
6) Transformer installation, operation must be conducted by a trained electrician
Fifth, cable safety precautions
1) submersible pump unit normal operation, the operator can not touch the cable should be kept at a distance with the cable.
2) After measuring the insulation resistance, discharge it to ground.
Sky wave pump industry: Original

Single two three four spindles CNC High Speed Drilling Machine for metal plate, clapboard, flange, tube plate, in the filed of petrochemical boiler and power flange industry, also for plate in building, bridge, iron tower etc.

1) High-speed internal cooling, high efficient processing
2) High rigidity, anti-shake resistance, high precision
3) Identify the CAD graphic files intelligently, and automatically convert into the processing programm; Support off-line programming
4) The most optimal processing sequencing, the most optimal path control

This equipment is an improved version double power heads Drilling Machine with high accuracy, high efficiency, high rigidity, high reliability, the work table is divided into four processing zones, and you can load and unload the workpiece and program while drilling. It can be used to drilling connecting plates, foundation plates, end panels, templates, flanges, structural components and other parts in steel structures, bridge building, power communication tower, heat boiler, etc.

This machine is mainly composed of movable gantry, base, table, support frame, movable support, left/right bracket, power head, automatic chip conveyor, circulation cooling device and electrical system etc.
