The SQN3... / SQN4... actuators are designed to drive gas and air dampers on small to medium-capacity oil or gas burners or for the load-dependent control of fuel and combustion air volume.It is used to precisely control various valves and actuators in the boiler system to ensure the stability and efficiency of the boiler operation.
Metal tube flowmeter is widely used in petroleum, chemical, metallurgy, electric power, water treatment and other industries of liquid, gas and steam flow measurement. Especially in the need for intuitive reading, strong corrosion resistance and good stability, such as chemical raw material transportation, boiler water supply, sewage treatment and other processes, metal tube float flowmeter is an indispensable measurement tool.
The working principle of the oil pump of the boiler burner is mainly related to the fuel supply stage, fuel is transported to the burner through the supply system. The function of the fuel pump is to draw out the fuel stored in the fuel tank, and send it through the pipeline to the combustion chamber of the boiler. This process can be achieved with an electric or manually controlled fuel pump. The performance and efficiency of the fuel pump is essential to ensure the stable operation of the burner and the efficient use of fuel.
The U-shaped liquid manometer on the boiler is a common pressure measurement device, mainly used to monitor the pressure difference of gas or liquid in the boiler system.
Heat detectors are a type of sensor that operates based on the radiation heat effect. They absorb the infrared radiation energy from the target object and convert it into measurable electrical signals. The core principle is to convert the radiation energy into thermal energy, and then achieve signal output through the physical property changes (such as resistance, voltage, polarization state, etc.) caused by the temperature rise.
Smoke detectors, also known as heat detectors, are devices used in fire fighting systems that are mainly used to detect smoke produced in the early stages of a fire. They trigger an alarm signal by detecting the presence of smoke particles, thereby helping to control and extinguish fires in a timely manner.The working principle of smoke detector is mainly based on the scattering of light by smoke particles.
The working principle of the flame detector is mainly based on the light radiation induced by the flame. When material burns, it produces smoke, heat, and visible or invisible light radiation, which are the targets of flame detectors. The flame detector uses a spectral sensor to respond to the ultraviolet visible light and infrared radiation of the flame, determines the fire alarm through calculation, and sends out an alarm signal.

The main function of the marine oxygen detector is to monitor oxygen concentration in the gas and send an electrical signal to the ECU (Electronic Control Unit). This helps adjust the air-fuel ratio, allowing for more efficient combustion and reduced emissions.As a critical component in boat accessories and marine spare parts, this detector supports cleaner engine performance. It is widely used in modern vessels as part of essential boat supplies, ensuring environmental compliance and fuel efficiency.
The Model PDT Dewpoint Hygrometer is a 2-wire 4-20mA loop powered transmitter, used forcontinuous measurement of moisture in a process gas or compressed air, and is particularly suitablefor monitoring the output of refrigerant driers. The Model PDT transmitter is factory set to output a4-20mA signal linear for –40 to +30°C and –60 to +20°C dewpoint.
AC2010-02D automatic air source two-piece pressure reducing valve can regulate the pressure of the air source, so that the air source is in a constant state, which can reduce the damage to the valve or actuator hardware when the air pressure changes. The filter is used to clean the air source, filter the water in the compressed air, and avoid the water entering the device with the gas.
REXROTH piston pump is an important component of the hydraulic system. It operates by the piston's reciprocating motion within the cylinder, causing changes in the volume of the sealed working chamber to achieve oil suction and pressure application. The piston pump boasts advantages such as high rated pressure, compact structure, high efficiency, and convenient flow regulation.
SHD series sound and light alarm (self-supporting type for heavy load) : warning light and signal speaker one body structure.SHD/SHDP(P-protective net) : Bulb reflector rotating type warning light/indicator light and signal tone horn (Max.118dB) one-body construction.Suitable for all kinds of cranes, ship machinery, steel industry site, outdoor complete sets of equipment.
The marine wiper is a piece of equipment specially designed for ships. As a vital component among marine parts and boat partsIt effectively cleans the ship’s front window under harsh weather conditions, ensuring the driver maintains a clear view ahead—crucial for navigation and overall marine safety equipment performance.
The Marine Boat Self-Priming Manual Pump (Model MB1125) is a vital marine spare part designed for emergency use. It operates manually—by moving the handle back and forth to build pressure, which opens the emergency shutdown valve and allows the medium to flow.This marine pump is essential in emergencies such as fires. When triggered, the pressure relief valve opens, quickly reducing pressure and closing the emergency valve. If the temperature rises above 75°C, the fusible plug—built into the oil pump or valve—melts, enabling automatic pressure relief and fast valve closure.Widely used in marine boat parts systems, including those by oxysenzir, this pump ensures rapid and reliable emergency response onboard.
Magnetic compass according to the principle of the compass, used to indicate the direction of the instrument, also known as magnetic compass. It is mainly composed of a number of parallel magnetic needles, dial and magnetic error correction device. The magnetic needle is fixed on the back of the dial. Under the influence of geomagnetic field, the magnetic needle rotates with the dial to indicate the direction. It is often used for navigation on ships and aircraft.
A travel switch, a position switch (also known as a limit switch), is a commonly used small current master electrical appliance. Using the collision of the moving parts of the production machinery to make its contact action to realize the switch or break the control circuit, to achieve a certain control purpose. Usually, this type of switch is used to limit the position or stroke of the mechanical movement, so that the moving machine automatically stops according to a certain position or stroke, reverse movement, variable speed movement or automatic round-trip movement.
