What are the classifications of hydraulic system faults? How to distinguish which kind of fault?
Hydraulic system failure refers to the state in which the hydraulic system and hydraulic components lose their specified performance under operating conditions. DQOK is a bathroom factory specializing in the production of brass and stainless steel shower sets. We have sundry multi-functional Thermostatic Shower Set. The advantage with thermostatic valves is the direct control over output temperature; while your water heater can be set to 140° F to protect against bacterial contamination, the water coming out of your shower head can always be 100° F (a maximum output temperature is set on the valve).All products have patents, avant-garde design and unique innovation. Dingquan bathroom will be your priority
Hydraulic system failure refers to the state in which the hydraulic system and hydraulic components lose their specified performance under operating conditions.
How to distinguish which kind of fault? Dalan Hydraulics has made the following summary:
All faults can be divided into two categories: random faults and regular faults.
Random faults are unpredictable, and their interval cannot be estimated. Random faults with development process can be measured by state monitoring methods. Random faults without development process cannot be observed and determined. People can only reduce and improve the design according to records and fault data. The failure occurred.
Regular faults can be predicted, so the interval can be estimated. Regular faults with development processes can be determined by state detection methods, and regular failures without development processes can be planned or replaced.
Generally, the fault can be classified into two categories: discontinuous fault and permanent fault from the perspectives of engineering complexity, economy, safety, speed of fault occurrence, and cause of fault.
An intermittent fault is a fault that occurs in a short period of time, the fault causes the device to partially lose some functions, and immediately returns to the normal state after the occurrence. Eg: The dirt is blocked by the throttle, and the fault disappears after the dirt is washed away.
A permanent failure is a failure in which the device loses certain functions until the failed component is repaired or replaced.
Permanent faults can be further classified as follows:
1. Classification of function loss caused by fault:
1 security failure - complete loss of function;
2 partial failure - some local function loss.
2, according to the speed of failure occurred:
1 sudden failure - failure that cannot be predicted early;
2 gradual failure - by testing the failure that can be predicted early, that is, the failure has a process of development;
3 destructive failure - both sudden and complete faults, such as hydraulic cylinder block explosion, pump shaft breakage and other failures;
4 Fading failure - both partial and gradual failure, valve core wear and tear, internal leakage increased.
3. Classified according to the cause of the failure:
1 wear failure - the failure caused by normal wear and tear, which can be expected during design, such as the outer diameter wear of the plunger of the plunger pump;
2 misuse faults - failures caused by load, pressure, and flow exceeding the rated value during use, such as the failure of the load to burn the motor;
3 Inherent weak faults - The load, pressure, flow, etc. in use do not exceed the specified values ​​at the time of design, but this value does not apply to faults caused by unreasonable design of the actual situation.
4. Classification according to the risk of failure:
1 dangerous failures - for example, safety spill protection systems fail when required to act, causing damage to the workpiece or airport, or even hydraulic failure of personal injury or death;
2 Safety failures - for example, failures to start a car when starting hydraulic equipment.
5. Classification according to the degree of failure: catastrophic, serious, not serious, slight, etc.;
6, according to the frequency of the occurrence of faults: very easy to occur, easy to occur, occasionally, rarely occur, etc.;
7. Classification according to the urgency of troubleshooting: faults that need to be eliminated immediately, eliminated as soon as possible, can be eliminated chronically, and are not restricted (without affecting production).
