Multi-way Valve Grease Filling
Sep 06, 2018

The multi-way valve is an important part of the machine equipment. The damage of this part may cause the whole machine to be inoperable, so the maintenance of the multi-way valve becomes more important. Today, I will tell you about a more effective maintenance method. - Multi-way valve grease maintenance.

When the first and multi-way valves are greased, it is easy to ignore the amount of grease. After the grease gun is refueled, the operator selects the multi-way valve and the grease-bonding method to perform the grease-filling operation. There are two situations: on the one hand, insufficient amount of grease is injected, resulting in a lack of lubricant and wear. On the other hand, too much grease is injected, causing waste. It is not based on the multi-way valve type to accurately calculate the different valve sealing capacity. The sealing capacity can be calculated in terms of multi-way valve size and type, and a proper amount of grease can be injected reasonably.

Second, when multi-way valves are greased, pressure problems are often ignored. During the grease injection operation, the grease injection pressure changes regularly in the peaks and valleys. The pressure is too low, the seal leaks or fails, the pressure is too high, the grease injection port is blocked, the seal grease hardens or the seal ring and the valve ball and the valve plate are locked. Usually, when the grease pressure is too low, the injected grease flows into the bottom of the multi-way valve chamber. On the one hand, the grease injection pressure is too high. On the one hand, the grease injection nozzle is checked. If the grease hole is blocked, the situation is replaced. On the other hand, the grease is hardened. The cleaning fluid is used to repeatedly soften the failed sealing grease and inject a new grease. .
