Hydraulic system failure analysis 2019-06-22

The hydraulic system is a complex collection of mechanical, hydraulic, electrical and other fields, so once the system fails, it is more troublesome to eliminate. To analyze the cause of the fault, first of all, to have an overall understanding of the role of each component in the schematic diagram, to understand the hydraulic system schematic diagram, and then to analyze and troubleshoot according to the fault phenomenon. The flow of the transmission medium in the hydraulic system in the components and pipelines is not visible outside, so it brings certain difficulties to the troubleshooting. Therefore, the relevant personnel must have strong analytical capabilities, and the whole system is complicated. Identify the cause of the failure and eliminate it in the connection relationship.waste paper hydraulic baler is one of using the hydraulic system equipment .

1 Hydraulic Drive System Fault Overview
1.1 Fault division

According to the causes of hydraulic system failure, it can be roughly divided into three categories: (1) abnormal pressure value. In order to effectively monitor the operation of the hydraulic system, a lot of pressure test points are reserved during the pipeline design, and the pressure gauge is installed to monitor the detection points. By comparing with the normal values, the hydraulic components with abnormal pressure can be found in time. Pressure loss is: pressure loss along the path, partial pressure loss. When the pressure is overloaded, the relief valve overflows. When the relief valve is not working properly, the system pressure cannot be guaranteed normally, which requires us to effectively monitor the operation of the hydraulic system; (2) the flow rate is abnormal. When the hydraulic system is in operation, the oil output from the hydraulic pump enters the hydraulic cylinder to force the seal volume formed by the cylinder and the piston to increase, resulting in movement of the piston (or hydraulic cylinder). Its speed of movement is related to the flow into the hydraulic cylinder. So first check to see if there is any leak in the connection in the working system. By adjusting the throttle valve, the speed regulating valve and the variable pump variable mechanism one by one according to the schematic diagram, the speed range value of the actuator is observed, and then compared with the design value to determine; (3) the operation is abnormal. The abnormal reaction of the work is that the action of the actuator is largely different from the predetermined one, and the work process is accompanied by vibration, noise, high working temperature, and large hydraulic shock. Perform a switching test on each of the reversing valves to see if the action of each actuator is normal, and then find the abnormality, then check the execution sequence and stroke control to find the fault.as more information ,please contact : www.nkbaler.com

Hydraulic baler failure and maintenance 2019-06-17

When the hydraulic baler is working, the hydraulic baler fails, what are the common faults and maintenance methods of the motor? The normal operation of the hydraulic baler motor and pump is due to the abnormal noise of the motor: the hydraulic baler, the silage corn hydraulic baler motor bearing damage; the motor is not synchronized.
  The reason why the hydraulic baler cannot be started is: the power is not turned on; the fuse is blown; the overload protection action; the wiring of the control device is wrong. The reason why the hydraulic baler motor vibrates strongly is that the motor is inconsistent with the mechanical center of the drive; the coupling fails; the unit loses balance, the foundation is not strong, and the rotor is set to contact the broom: the free warranty period of the hydraulic baler is 1 year. Hydraulic baler, silage corn hydraulic baler Master the common faults of the hydraulic baler motor, check the repair method, and ensure the normal use of the baler equipment is very important.
  The large allowable pressure of the hydraulic baler under conditions of rated pressure, according to the test standard, the large pressure value of the hydraulic pump that allows the hydraulic baler to operate briefly is called the large allowable pressure. For each rotation of the hydraulic pump, the volume of the discharged liquid calculated by the change of the sealed volume of the hydraulic baler is called the displacement of the hydraulic pump, the hydraulic pump with the adjustable displacement is called the variable pump; the hydraulic pump with the constant displacement It is called a metering pump.
  Hydraulic Baler Working Pressure The output pressure of the hydraulic pump of the hydraulic baler is actually called the working pressure. Regardless of the flow rate of the hydraulic pump, the hydraulic baler, the working pressure of the silage corn hydraulic baler depends on the size of the external load and the pressure loss on the discharge line. The rated pressure of the waste paper is based on the test standard. The hydraulic pump of the hydraulic baler is called the rated pressure of the hydraulic pump under normal working conditions.

Analysis and elimination of common faults in hydraulic cylinders (2) 2019-06-13

Analysis and elimination of common faults in hydraulic cylinders

Among the many causes of hydraulic cylinder failure, improper installation, use, and maintenance are important causes of failure.
2 Why is the hydraulic cylinder not sensitive (blocking), how to eliminate it?

The hydraulic cylinder is not sensitive to the movement of the hydraulic cylinder. This phenomenon means that the hydraulic cylinder cannot be operated immediately after the instruction of the hydraulic cylinder is issued, and it takes a short time to operate, or it can be stopped when it is moving, and the operation is very irregular. The main causes and troubleshooting methods for this fault are:

1) There is air in the hydraulic cylinder. Remedy: Exhaust through the exhaust valve. Check the seal ring at the reciprocating part of the piston rod for air inhalation. If so, replace the seal.

2) There are irregularities in the operation of the hydraulic pump, and the pump rotation has a block or a slight seizure. Remedy: According to the type of hydraulic pump, according to the reasons for its failure, solve the problem separately. For details, please refer to the relevant information.

3) When the hydraulic cylinder with the buffer device is started in reverse, the piston temporarily stops or reverses. Remedy: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above-mentioned failure phenomenon occurs when the buffer plunger leaves the end cap. In this regard, the orifice of the check valve should be enlarged.

4) When the piston movement speed is high, the steel ball of the check valve follows the oil flow, so that the valve hole is blocked, and the hydraulic cylinder causes the movement to be irregular. Remedy: Replace the steel ball with a poppet or spool with a guide shoulder.

5) The inner layer of the rubber hose is peeled off, so that the oil passage is broken and the hydraulic cylinder is irregularly moved. Remedy: Replace the rubber hose.

6) The hydraulic cylinder is subjected to a certain lateral load. Remedy: Same as the method of "the hydraulic cylinder can't move".
