In recent years, the guide rail elevator equipment has received unanimous praise from our customers, and production orders have continued to rise. As more and more consumers choose, the problems of the guide rail elevator equipment also appear, so the elevator guide rail equipment is in use. How to improve the service life?
The hydraulic system of the elevator guide rail equipment is the main factor affecting the instability of the gate valve components, causing the instability of the liquid circulation. The direct consequence is the abnormality of the supercharger, which shortens the normal service life of the guide rail.
The main medium of railway elevator is hydraulic oil. Hydraulic oil easily expands and contracts. After starting, the system medium is heated in cold state. The door opened when the weather was hot and cold. According to the introduction of the rail lift and crane, if the system takes some measures, the pressure of the rail lift will inevitably increase.
The normal opening and closing of the rail lift valve is the key to industrial process control. Valve housing hydraulic lifts, caps and other extreme pressures. When the pressure is very dangerous, when the medium is high temperature gas, toxic and harmful gas, easy to corrode and pollution is more serious, they are easy to cause mechanical damage. Equipment and personnel, sowing seeds of potential safety hazards, should be checked for partial overpressure in a timely manner.
Elevator guide-type valve housing, bonnet and valve stem part with valve design strength, the strength of abnormal pressure nominal pressure, the opening pressure will double, and cause the use stress of related parts to increase exponentially, when the actual stress exceeds the allowable With stress, high-stress areas produce fracture damage, resulting in the valve not being able to open, and the valve and machine can be damaged or destroyed.
