How to maintain and maintain the valve of ZYB-B burner pump to teach you a few tricks! 1. The valve should be stored in a dry and ventilated room, and both ends of the passage must be blocked. 2. Valves stored for a long time should be inspected regularly to remove dirt and apply anti-rust oil on the processing surface. How to maintain and maintain the valve of ZYB-B burner pump to teach you a few tricks!
1. The valve should be stored in a dry and ventilated room, and both ends of the passage must be blocked.
2. Valves stored for a long time should be inspected regularly to remove dirt and apply anti-rust oil on the processing surface.
3. After installation, it should be inspected regularly, mainly for inspection items:
(1) Wear of the sealing surface.
(2) Trapezoidal thread wear of the stem and stem nut.
(3) Whether the filler is out of date or not, and if it is damaged, it should be replaced in time.
(4) After the valve is overhauled and assembled, the sealing performance test shall be carried out.
The maintenance work of the valve during grease filling is professional maintenance work before and after the production of the valve, which plays a vital role in the service of the valve. Correct and orderly and effective maintenance will protect the valve. The valve functions properly and extends valve life. Valve maintenance work seems simple, but it is not. There are often neglected aspects of work.
First, when the valve is greased, the problem of the amount of grease is often ignored. After the grease gun is refueled, the operator selects the valve and the grease injection method to perform the grease filling operation. There are two cases: on the one hand, the amount of grease is less than that of the grease, and the sealing surface is accelerated by the lack of lubricant. On the other hand, excessive fat injection causes waste. The ZYB-B burner pump is based on the type of valve type, and Botaibang accurately calculates the sealing capacity of different valves. The sealing capacity can be calculated in terms of valve size and type, and a proper amount of grease can be injected reasonably.
Second, when the valve is greased, the pressure problem is often ignored. When the ZYB-B burner pump is in the grease injection operation, the grease injection pressure changes regularly in the peaks and valleys. The pressure is too low, the seal leakage or failure pressure is too high, the grease injection port is blocked, the seal grease is hardened or the seal ring is locked with the valve ball and the valve plate. Usually, when the grease pressure is too low, the injected grease flows into the bottom of the valve chamber, which usually occurs in a small gate valve. 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. . In addition, the sealing type and sealing material also affect the grease filling pressure. Different sealing forms have different grease filling pressures. Generally, the hard sealing grease pressure is higher than the soft sealing.
