Sliding-blade air compressor 802055 field application and fault treatment. Aluminum Qinghai Branch Electrolytic Plant Qinghai 810108 Zhou Jingcheng Zhou Hailu Peng Guo Zhang Cheng discussed.
The latch, 2055 along the principle of the chip air compressor, the air passes through the filter and adjusts the proportional valve into the pressure chamber. The pressure chamber is composed of the cylinder stator and the rotor. The rotor rotates eccentrically with respect to the cylinder, and the valve plate is mounted on the rotor. In the groove, the valve plate slides in the groove, and the slide piece is pushed to the cylinder wall by the centrifugal force. During the air compression process, the volume between the vane and the cylinder of the compressor rotor is continuously reduced to achieve compression of the air. The compressed oil and gas mixture enters the oil chamber from the pressure chamber, and the oil is separated by the labyrinth structure and the filtering device, so that the compressed air contains less than 34 oil, and the purified compressed air enters the radiator for cooling and output. Then, the intelligent controller stomach 0 device is separated by condensed water, and the four condensate drain valves are sequentially controlled to open and close, and the condensed water is discharged. 1.

Air filter MATTEI sliding plate press Features Rotor structure and lubrication mechanism The rotary vane air compressor adopts a rotary vane design, which is fully slip-proof so that there is no friction between the cylinder and the cylinder.
Rotor transmission and internal components are connected by a maintenance-free flexible coupling. No transmission belt or speed-increasing gear is required. Only the rotor rotates when the compressor is running. No complicated roller bearings are required. Moreover, the use of babbitt as the bearing bush does not require replacement of the bearing bush.
The segmental oil and gas separation system and the intelligent condensate discharge treatment system ensure that the oil in the air is effectively removed. The standard discharge air contains less than 2% of the parent oil, and the compressed air output from the unit contains very little oil and moisture. The gas supply quality is excellent.
The servo system is equipped with a fully automatic stop start and a fully automatic unloading and heavy load double control system. Under continuous operation, the air intake can be automatically adjusted according to the amount of air used outside to maintain a stable output pressure and keep the internal gas constant. Pressure state. When the external air consumption is reduced, the unit automatically unloads; when the outside world does not need compressed air, the unit automatically discharges the pressure inside the machine to atmospheric pressure and enters the standby or shutdown state.
The stable intelligent electronic control system is simple and highly intelligent electrical control, which can effectively avoid the external GM operation and the monthly operation, and the maintenance of 0 A, the signal interference generated from 01 æ™·6. Among them, the data recording function of the intelligent controller can record the fault data in detail, which provides convenience for fault diagnosis and processing of the unit.
Continuous operation mode 0 The air compressor 1 can be stopped only when the operator presses the stop clamp; the maximum working pressure of the air compressor is determined by the solid state control system; 833, which is determined by the single parameter. When the working pressure of the air compressor reaches the maximum air pressure setting, the air compressor automatically stops. When the air compressor unit is 1.51031.5181, the air compressor is turned into the no-load state.
The automatic operation mode is to immediately lower the air compressor when the externally required compressed air pressure is reduced or the external compressed air is not required. For example, 1 air compressor is busy at 1 and 3, such as 0.1. Before the unloading time in the dish, the compressed air pressure output by the unit reaches the minimum output pressure value, and the air pressure machine is transferred to the load operation mode again.
1. The adjustment of the air compressor pressure servo valve 讪 The adjustment of the servo valve can control the air compressor, the large working pressure and the unloading pressure, but for a certain model, the 0 air compressor is shipped from the factory. Adjusted to the best working condition. If a small range of adjustment is required during field use, make sure that the maximum servo pressure given by the corresponding model air compressor cannot be exceeded. The maximum servo pressure is 7.5, 107.51 compared to the 120551 air compressor.
(1) Enter, 上 adjust the value of the elbow to the required unit servo pressure value.
Start the air compressor, then slowly close the automatic suction valve until the servo valve is actuated, or until the internal pressure value of the unit reaches the maximum price, then proceed to the valve adjustment step to remove the left end cover of the air compressor, you can see To the air compressor servo valve, adjust the servo valve pressure to adjust the hexagon socket screw. That is, the servo pressure of the loosening screw is reduced, and the working pressure of the tightening screw is increased until the servo pressure is adjusted to the desired value. At this time, attention should be paid to the pressure index check on the gas oil separator. Then slowly open and close the automatic inhalation valve, check that the set pressure value is correct, and finally tighten the servo valve pressure adjusting lock nut to lock the servo pressure adjustment screw.
Replace the relevant parts of the air compressor servo system, cover the end cover and tighten the end cover protection lock and 8 people 33 æ±². , 01 menu stores the adjusted servo pressure value.
The fault type and processing controller of the daily 2055 air compressor are working normally, and the air compressor can also be started, but the air compressor motor cannot be switched correctly.
The controller works normally, and the green 0 start indicator on the controller can also be lit, but the air compressor cannot be started.
The working pressure of the air compressor system does not reach the predetermined force value.
The internal pressure of the air compressor cannot reach the set pressure.
The air compressor oil consumption is too large, the oil level drops too fast, and oil is mixed in the compressed gas system.
The air compressor temperature is too high, causing the unit to stop.
The operating temperature of the air compressor motor is too high, causing the unit to stop.
A large amount of running oil appeared at the servo valve, and the fuel injection air compressor was periodically exhausted.
The air compressor continuously vents continuously, and the remote cannot stop normally.
The noise of the air compressor is intensified, and the noise tone is sharp. When the controller works normally, the air compressor can also start. However, when the air compressor motor cannot correctly switch the contactor, the electrical main circuit of the air compressor should be inspected in detail. Confirm the good condition of the switching contactor of the main contactor, measure the coil voltage resistance, determine whether the main circuit fault or the control loop fault; at the same time, measure the phase power voltage value of the main loop within the allowable range to prevent excessive voltage drop. The startup fault recovers the electrical main circuit voltage, replaces the damaged electrical device to normal, and restarts. When the controller works normally, the green recognition 0 start indicator on the controller can also be lit, but when the air compressor cannot start, Checking the air compressor cycle of the air compressor and the failure of the pressure measurement sensor can cause this fault. Detect the pressure value of the pressure on the body of the gas oil separator, and compare it with the pressure value set inside the controller. Also check the operation of the pressure control system, and measure whether the control wiring of the sensor and the switching of the solenoid valve are normal. .
The working pressure of the air compressor system does not reach the predetermined pressure value. The working pressure of the system does not reach the predetermined value. It is often incorrect for the same week. The servo valve pressure is adjusted again. The condensate outlet solenoid valve is blocked. The solenoid valve is detailed. Check to eliminate the cause of the blockage and test that it is working properly.
The filter of the air inlet is damaged or blocked. If necessary, replace the over-running and maintenance.
The demand for external compressed gas exceeds the maximum capacity of the air compressor. Consideration should be given to whether the compressed air line is damaged or leaking, or the external pneumatic equipment is faulty.
3 The internal pressure of the air compressor cannot reach the set pressure value parameter value for inspection and correction.
4 Air compressor oil consumption is too large, the oil level drops too fast, there is oil in the compressed gas system, or black smoke at the air inlet.
The return filter is damaged to become clogged and the return filter is replaced.
The gas oil separator filter element is damaged or severely clogged, right! 1 Check the status in detail and replace if necessary.
If the oil in the return valve line is too much or the oil color is black, the return valve may be seriously blocked or damaged, and the return valve should be cleaned and replaced. It is often the case that a small amount of clear oil flows through the soft transparent oil line connected to the helium valve.
5 The temperature of the air compressor is too high, which causes the radiator of the air compressor to be blocked or uncleaned, resulting in poor heat dissipation. After determining the cause, the radiator should be thoroughly cleaned and dusted. If the radiator is damaged, it should be completely replaced. . If the ambient temperature of the indoor or air compressor operating site is too high, you should consider increasing the radiator or additional cooling device to meet the operating environment temperature of the air compressor. The operating temperature of the air compressor motor is too high, resulting in the operating temperature of the unit shutdown motor. Too high, the main cause of unit shutdown is the severe wear of the motor bearings, which is often accompanied by abnormal sounds. At this time, the motor temperature should be tracked and measured and recorded. The motor bearings should be carefully inspected and the motor bearings should be replaced if necessary. At the same time, in the daily maintenance, the grease of the motor bearing should be lubricated with lithium grease every month.
Check that the cooling condition of the motor is normal. When there are no other abnormalities, consider improving the cooling effect of the motor.
Empty 1. The pressure of the machine 1 is too high, and the pressure of the plate should be appropriately lowered. After checking the pressure setpoint, the pressure can be lowered to below 77 for the å±20551 unit.
A large number of oil-injection servo valves appear at the servo valve, and there are a lot of oil or fuel injection. It is often the air compressor servo valve core, and the seal ring is replaced.
Air compressor periodic exhaust termination The most direct cause of periodic exhaust termination is that the hole 0 controller has no output signal, or the output line has a virtual connection or disconnection fault. First, the internal program of the controller should be checked to correct the program error. , re-wired correctly.
The sequential discharge solenoid valve is blocked or the coil is damaged, and the solenoid valve cannot operate reliably. It is possible to test whether the state is good by adjusting the coils of the sequential discharge valves in the field.
The air compressor continuously vents continuously, and the far-end cannot stop normally. The most direct cause of continuous exhaust fault is that the controller output signal is abnormal, and the internal program performs an unexpected error and the output lock occurs. Stop the air compressor, cut off the control power, and re-power the power to reset.
The solenoid valve spool is faulty in sequence and normal closing action cannot be achieved.
The peripheral compressed air line is damaged and the compressed air is leaked.
This should identify the point of failure of the pipeline and promptly repair or replace it.
The noise of the air compressor is intensified, and the noise tone is sharp. The 20551 air compressor of the team has a certain noise under normal working conditions. The source is mainly the sequential emission noise of the compressed air of the fan air compressor motor of the unit air cooler. If the noise is sharply increased, the bearing of the motor is often less lubricated, or wear has occurred, and the motor bearing should be inspected in detail.
If the main circuit of the air compressor is overhauled, or the power supply of the power distribution is repaired or the maintenance of the phase cable is carried out, the phase sequence of the air compressor motor should be checked in detail to avoid correcting the air compressor. This in turn caused severe damage to the unit.
The field application fully embodies the failure of the 02055 vane type air compressor for the application of the 4-slide air compressor, and combines advanced fault diagnosis measures to find out the cause of the fault. In the application, we continuously accumulate maintenance experience, improve the maintenance level, and give full play to the outstanding performance of the vane air compressor.
