Saiken Pump Industry will explain to you the important role of gear oil pump safety valve:
The safety valve is also an important accessory part of the positive displacement gear oil pump. Each positive displacement gear needs to be equipped with a safety valve. If the pump is self-provided, it is not necessary. The repair of the safety valve of the gear oil pump is mainly the repair of the sealing surface of the safety valve. Therefore, there are higher requirements for the sealing surface material of the safety valve. The basic requirement is: high strength, can withstand high sealing pressure: a certain degree Impact resistance and toughness, can withstand the impact of the rapid take-off and return of the valve core: high hardness, can withstand medium erosion: can not rust, otherwise it will leak quickly: to be resistant to high temperatures, can be applied to steam and other media, and will not soften at high temperatures: To be corrosion resistant, can withstand acid and alkali corrosion.
The type of safety valve on the oil gear pump The safety valve for positive displacement gear pump has two forms: spring safety valve and one-time safety valve. Types of safety valve on the gear oil pump Safety valve for positive displacement gear pump has spring safety valve and There are two forms of one-time safety valve.
Safety valve return pressure Ph When the discharge pressure of the gear oil pump is less than the safety valve return pressure, the safety valve is closed. Obviously there is no return pressure Ph for the one-time safety valve. When the discharge pressure of the gear pump is greater than the kick-off pressure Pk, the safety valve is opened to release the pressure to a predetermined level.
