The hydraulic oil tank is equipped with a partition to prevent excessive fluctuation of hydraulic oil, increase the circulation distance of hydraulic oil, so that the hydraulic oil has enough time to separate bubbles, precipitate impurities, and dissipate heat. The hydraulic oil tank is equipped with an oil suction filter and an oil return filter, whic
1 The role of the filter in the hydraulic system The role of the filter in the hydraulic system is: 1) Filter the dirt particles in the oil, prevent the moving parts from jamming, parts scratches, oil passage blockage and other failures, and improve the reliability and stability of the system. 2) Filter out fine particles of impurities in the oil, prevent abras
Pressure switch characteristic Understanding system dynamics is essential for switch selection. Here is a list of questions to answer when specifying the pressure switch: How often is the switch activated? Electromechanical switches are prone to fatigue. Bourdon tube or diaphragm switches typically provide 1 million cycles compared to piston or diaphragm sealed piston switches that provide 2
Float flowmeter indispensable accessories - magnetic filter
Float flowmeters include metal tube float flowmeters and glass float flowmeters (glass rotor flowmeters). Generally speaking, the float flowmeter is suitable for small pipe diameter and low flow rate working environment, commonly used instrument diameter is below 40-50mm, the minimum diameter is 1.5-4mm. Taking liquid as an example, the nominal pipe diameter of the full degree flow of the glass tube float flowmeter with a diameter below 10mm has a flow rate of only 0.2-0.6m/s, or even lower than 0.1m/s; The metal tube float flowmeter and the glass tube float
