How to choose solenoid valve grease

First of all, we need to look at the type of solenoid valve, which is divided according to the working frequency:< /span>

Less than 10 times/second is low speed,

More than 10 times/second is considered high speed,

30-60 times/second is considered super high speed.

solenoid valve with different speeds, it controls the oil The requirements are quite different, and the requirements for grease adhesion, water resistance, wear resistance and other requirements will also be different.

Because the amount of grease used in solenoid valves is very small, the amount of grease inside a valve is about 0.1-0.2 grams, and the use of automated grease filling equipment can effectively reduce the waste of grease, and the precise control of the amount is excellent, so most manufacturers do not care much about the price of grease , mainly depends on the quality of the oil.

BecauseSolenoid valve has high requirements on grease life and wear resistance, so synthetic grease is required to start, and at the same time, it is necessary to choose adhesion and water resistance Excellent impact resistance and wear resistance.

As we all know, solenoid valve grease is used with sealing rings. The sealing rings are generally made of PTFE. This material will wear out under long-term working conditions.

Experimental verification: Under non-laboratory working conditions, when coated with the industry's top fluorine grease, the sealing ring will wear a small amount after about 15 million operations, but this will not affect the working performance. The lifespan can reach about 60 million times, but the disadvantage is that it is expensive.

The non-top grade grease currently used in the industry is generally fully synthetic lithium-based grease. The general working life is more than 10 million times. Under different working conditions, the life span will fluctuate, and some can reach 20 million times. The price is cheap, and the price generally fluctuates within 1,000 according to different brands, while the top-grade fluorocarbon grease is generally 8-10 times the price.
