The Knock Sensor is located on the engine block, cylinder head or intake manifold. This is because its function is to sense vibrations caused by engine knock or detonation. The PCM uses this signal to alter the ignition timing and prevent detonation. It will compare this information with its preset tables to identify a valid knock or ping. If a ping is sensed, it will retard the ignition timing to protect the engine from this damaging pre-ignition.

Explosion-proof accident exhaust fan control box how to purchase:
1. Custom explosion-proof accident ventilator control box, we must first provide explosion-proof accident ventilator control box riot signs. Such as: ExdeIIBT6
2. It is best to directly provide the model of the explosion-proof accident ventilator control box, or the outline drawing and electrical schematic diagram; if there is no need to provide explosion-proof distribution box categories (lighting or power), product characteristics (how many loops), In and out of the line (number and size and direction), leakage protection, installation environment and methods, internal electrical brand (Ore conventional electrical brand ABB, Schneider) and so on.
3. Under normal circumstances, explosion-proof accident exhaust fan control box master switch is 3P, sub-switch is 2P; Explosion-proof power distribution box master switch and sub-switch are 3P; if the switch technology has different requirements, need to be described separately.
4. If the switch inlet and outlet specifications, direction, and switch current are different, the number of corresponding circuits must be described separately.
5. If the explosion-proof accident ventilator control box switch is to be leaky, the leakage current shall be described separately for the corresponding circuit number.
6. Can be customized according to special requirements. (Ouri common materials: copper-free aluminum alloy, carbon steel, stainless steel) BEP56 explosion-proof distribution box technical data!
Hazardous area: Combustible gas and flammable dust may appear at the same time or separately. The shell is welded by steel plate and the surface is sprayed. The main chamber and wiring chamber are all flameproof.
Optional components such as high breaking circuit breakers, AC contactors, thermal relays, control buttons, and signal lamps can be installed. The handles can be opened and closed using the handles on the cover of the housing. The performance is reliable and the indicator lights are provided.
The incoming and outgoing wires can be either steel pipe or cable wiring. The direction of the inlet and outlet lines and internal components can be determined by the user.
The perfect combination of technology:
Cutting: Using shears, plasma cutting machines and other equipment according to the requirements of the drawings.
Bend: Formed using a bending machine.
Welding: AC arc welding machine (or AC-DC argon arc welding machine) welding, to ensure the sealing of the welding.
Polishing: Performs a burr finish on the welded and welded surfaces of the welded product. Or use a high-precision surface grinder for the flameproof surface to ensure the accuracy of the flameproof surface.
Drilling and tapping: Use special special drills, clamps, drilling and tapping the component mounting holes on the plastic housing.
Inlet and outlet holes. Each unit product has a complete set of tooling drills,
Clamp tool and product processing process documentation.
Pickling, Phosphating: The product surface is cleaned to ensure surface quality.
Spraying: Adopting domestic advanced “high-voltage electrostatic spraying†process to improve plastic layer adhesion.
Anti-corrosion performance has increased significantly. (Stainless steel products do not need coloring)
Assembly: Strictly follow the "Assembly Operating Procedures" and "Product Assembly Work Instructions" for assembly.
Inspection: In strict accordance with relevant national standards and "product inspection guidance card" for inspection,
When manufacturing this unit product, each process has a full-time quality inspector to carry out process quality inspection.
All inspection reports are recorded on file and saved to ensure the traceability of quality control.
