The importance of the correct installation and use of magnetic level gauge
When the magnetic flap level gauge is installed, a shutoff valve is installed between the upper and lower liquid distribution pipes of the measured container to open or collect the liquid level gauge. The magnetic flip liquid level gauge on the other hand facilitates the maintenance of the liquid level. When the upper and lower shut-off valves are closed, the bottom drain flange of the level gauge can be opened or the drain screw can be removed, and the main body of the level gauge can be cleaned by injecting clean water. 2, install the level gauge, flange center line perpendicularity ∠4 ‰, when the level gauge measurement range is greater than 3 meters, you need to consider increasing the middle reinforcement flange (or ear climbing) as a fixed support to increase strength. 3. The cross-sectional area of ​​the core wire connecting the remote liquid level transmitter and the secondary instrument should be greater than 0.8mm2. When laying parallel with the AC power supply, at least 20 centimeters or more should be maintained. Pipe laying, or laying with shielded two-core cable, shielding layer can only be grounded at one end. 4. The liquid level controller is selected, and the contact capacity of the liquid level controller is designed for resistive loads. If non-resistive or high-power loads are used, intermediate relays are used for conversion. 5. When the liquid medium contains suspended impurities and magnetic substances, it is not appropriate to use the level gauge (because these impurities will cause blockage on the float assembly). 6. The “L1†in the outline structure diagram is a side-mounted level gauge. The “Sink distance†parameter must be understood by the user. This parameter is related to the density of the medium. According to the principle of buoyancy, the length of the float assembly is related to the density of the medium. Therefore, different parameters must be taken into consideration when selecting and designing. Magnetic flap level gauge installation and maintenance of important steps: 1, magnetic flap level gauge installation must be vertical to ensure that the float assembly can move up and down freely in the main tube, 2, the container and the level gauge installed between the cut-off Valves for cleaning and servicing the liquid level cut off the material. 3. The proximity of the magnetizer is not allowed around the main tube of the level gauge, otherwise it will directly affect the normal operation of the level gauge. 4. After the installation of the liquid level gauge, it is necessary to use magnetic steel for correction, and guide the column once to make red below zero and white above zero. 5. When the level gauge is put into operation, the lower inlet valve should be opened to allow the liquid medium to enter the main tube smoothly, avoiding the liquid medium with the floating ball assembly to rise rapidly, causing the column to turn black and failing or turning over (if this phenomenon occurs) After the level of the beam is stable, the magnetic steel can be used for recalibration. 6. In order to prevent damage to the float ball assembly during transportation, the float ball assembly is taken out of the main tank of the small level gauge before shipment. After the level gauge has been installed, open the bottom drain flange and reinstall the float ball assembly into the main tube. Note that the weight of the float assembly is upward and cannot be flipped. 7. According to the condition of the medium, the sewage cleaning flange can be periodically opened to clean the precipitation of the main body of the pipe. With the above installation steps and technical knowledge overview, you can allow users to properly install the magnetic flip level gauge to extend the life and improve the measurement accuracy! ! Marine Electro-hydraulic Windlass The windlass is installed on the main deck of the ship's bow, which is used for the ship to lift the anchor and drop the mooring cable.

Windlass can be divided into manual, electric, hydraulic, pneumatic, etc. according to the driving form.
The windlass can be divided into several specifications such as φ12--φ120mm according to the diameter of the anchor chain.
Windlass can be divided into single-sided and double-sided according to the distribution of drums.
The windlass is mainly composed of base, bracket, chain wheel, brake, chain wheel, gearbox, electric control system (except manual windlass), etc. Electric windlasses have electric motors, and hydraulic windlasses have hydraulic pump stations.
The main technical indicators of the windlass include the diameter of the anchor chain, the nominal speed of the anchor, the rated load, the supporting load, several levels of speed change, electrical system, etc. The installation of the windlass on the ship should ensure that the wrap angle between the anchor chain and the sprocket is 117-120°.
Electric windlass
The electric motor directly drives the windlass, and the drive shaft is driven by the gear box to work, and the structure is simple; it is generally suitable for windlasses with an anchor chain diameter of 16mm-93mm.
hydraulic windlass
It is suitable for windlass with anchor chain diameter of 16mm-120mm. Hydraulic windlasses are also called electro-hydraulic windlasses. It drives the oil pump with a motor, drives the motor with high-pressure oil, and then drives the transmission gear through a reducer (or no reducer). To make the windlass run, its structure is relatively compact and its volume is small. Now there has been an automatic hydraulic windlass, which is equipped with an anchor chain length sensor. When the anchor chain needs to be thrown out, the windlass will automatically stop; , can automatically decelerate; the anchor will automatically stop when it enters the anchor chain drum and is properly received.
