Application of Ingersoll Rand Micro-oil screw air compressor in production

This paper introduces the working performance of the micro-oil screw air compressor and the proposed solutions to the problems that arise in use.

Ingersoll Rand micro-oil screw air compressor is widely used in various industries such as chemical metallurgy and mineral processing with its stable performance and advanced control methods. The whole system is mainly composed of the host and motor system lubrication and cooling system pneumatic system oil and gas separation system control system and protection system. The following is a brief introduction to the lubrication and cooling system pneumatic system control system that requires special attention during routine maintenance.

1Lubrication and Cooling System Ingersoll Rand's micro-oil screw machine lubrication and cooling system consists of the main engine separation cylinder temperature control valve oil cooler coolant filter oil cut-off solenoid valve and main engine, the coolant circulation is generated by the unit operation The pressure difference mountain is under high pressure and low voltage transmission. The specific working process is that the motor drives the main engine to rotate, and the coolant is injected into the separator through the oil passage from the high side of the main machine. From the separator part into the oil cooler, the fan is cooled, and some directly enter the temperature control valve. The temperature control valve cools the two parts according to the temperature requirement, and then resets the controller, and then checks other temperature transmitters.

5.93 After the verification is completed.ç ¬ Set the temperature of the controller for this purpose. And wait for the temperature to drop below 1001 to move the calibration furnace, such as verifying the furnace to put back into the grandfather. It must be confirmed that the furnace temperature is not higher than room temperature.

6 Precautions Mix with uncooled oil and enter the oil coolant filter to remove impurities. Then through the oil cut-off solenoid valve into the low pressure of the main engine, the oil is routed to the micro-oil screw machine in the compression process is very hot. The requirements for coolant are extremely high. Therefore, in the process of use, 6.8 system connection is required to note the precision temperature of the D7, and the channel is connected to the temperature change data line of the standard probe channel connected to the switch.

6.9 Pay attention to the configuration of the standard probe during use to prevent damage caused by improper use.

7 verification result processing probe name model series number temperature range configuration, with pin by the precision platinum resistance precision thermocouple 935 please secret thermocouple 035 6. To keep the dry furnace, clean and no pollution, no foreign matter, 6.2 to the instrument Keep it in a vertical position to prevent the probe from falling out of the sleeve.

6.3 When removing the furnace cover from the ten-body furnace. Avoid burns and fire.

6.4 Do not operate the instrument near flammable materials.

6.5 Do not use liquid to clean the dry furnace.

6.6 After the fuse is blown, the fuse of the same type should be replaced immediately.

6.7 If the AC power supply fluctuates, turn off the power of the instrument immediately.

Verified. Temperature transmitter. Each technology is required to paste the certificate. Issue a certificate of verification, and issue a notice of verification results for non-compliance with technical requirements.

8 The use effect has been used since the application of the automatic temperature verification system.

In 2006 and 2007, a total of 562 temperature transmitters were tested. The automatic temperature verification system solves the problem of the time and time calibration of the even field temperature transmitter. + Only reduced the verification cost, accumulated savings of more than 100,000 yuan in inspection costs, and because the external inspection of the temperature transmitter is avoided, the impact on the production system due to the inspection is reduced, the production needs are better met, and the production can be produced in time. And operating to provide accurate data and evidence.

Use a special coolant to avoid the host's operation to ensure reliable operation due to improper use of the coolant. When the unit is in operation, the exhaust temperature of the main engine should be controlled at 80, 90, and the temperature should be close to or exceed 98. The oil cooler should be cleaned in time. The unit is operated for 8000 hours for 2 years, and the coolant is changed in time.

Since the air entering the main engine contains a lot of dust, it will cause damage to the bearings and rotor of the left machine. Therefore, the timely replacement of the coolant filter is also extremely important. The replacement period of the coolant filter is 150 hours for the initial operation and no operation afterwards. 2 hours.

3 pneumatic system Ingersoll Rand's micro-oil screw machine's pneumatic system is vented by the minimum pressure valve aftercooler condensate separator air filter 下 into the next 1 specific working process for the loading process. When the working pressure of the main road gas is less than the set value, the deflation valve closes the 14-inch machine to drive the boring machine to rotate, and the gas enters the separator after entering the main machine. Ke enters the cooler to cool down by the minimum force. 6. Enter the water island to separate the water vapor in the air, and finally enter the main line to complete the gas loading process.

The minimum pressure acts well when the pressure in the separator is less than 4.

It is closed at 188 hours, so the compressed air will not enter the main bamboo road during unloading, and the minimum force valve also acts as a check valve to prevent unloading, and the air of the bamboo road returns to the separator.

The function of the separator is to separate the air coolant sent from the host, the air enters the main line, and the coolant returns to the main machine for recycling.

Air filter applicators should be checked frequently to avoid failure. 4 Causes large dust to enter the main unit. Reduce machine life.

4 system system Ingeso stomach company's micro oil screw machine screwing system; to controller active circuit board stepping machine power board pressure sensor temperature sensor relay contactor and other groups of specific work process for pressing 30 controller Start button, generation 4 诏 motor contactor 伢屯, contact closure, 1 fan electricity as work, while auxiliary contact touch 42 closed, 55 broken 汕 solenoid valve has electric oil passage, auxiliary contact 阽 41 closed 1 The main motor contactor is energized, the 1 PCT main motor works, and the start-up process is completed.

Used to detect the torque and temperature of the unit; 1 stepper motor controls the size of the intake butterfly valve. 5 Problems and solutions in use 5.1 Machine temperature over two When the air compressor motor is a high voltage motor, the contactor used must be a single wire. Because if you choose a double coil to operate the contactor.

50 The controller issues a stop command, the oil shutoff solenoid valve is closed, and the oil circuit is disconnected, but after the tapping contactor trip coil is burned. The main motor can't stop, causing the main unit to burn down.

5.2 Control panel display inspection control system, can not start the machine after inspection, the intake butterfly valve and the stepper motor coupling are disengaged, resulting in the intake butterfly valve can not be normally opened and closed, unable to start. Solve the problem after replacing the coupling.

5.3 The temperature value of the control panel often fluctuates between 800, 10, 1. The temperature of the small machine is high. After the shutdown, the grounding effect of the shielded circuit of the electrical circuit is poor, resulting in interference of the temperature sensor transmission signal. The numerical value is not accurate. . After the shielded wire is grounded, solve it.

In addition, some fault phenomena such as the unloading of the cylinder and the overload of the fan motor are relatively easy to solve, and will not be enumerated here.

6 Conclusion Ingersoll Rand's micro-oil screw machine parts are more expensive, so it is crucial to ensure that the original maintenance is critical to reduce the consumption of parts and reduce the failure rate to ensure the efficient and stable operation of the equipment.
