Air Compressor Parts Adjustment Method

Automatic Control Pressure Switch Adjustment Method

Adjustment of pressure height: turn the pressure adjusting screw to the right to increase the set pressure, and vice versa to decrease the set pressure. Adjustment of differential pressure: turn the differential pressure adjusting screw to the right to increase the differential pressure range, and vice versa to decrease the differential pressure range. The adjustment screws are related to each other, so please adjust them properly. Please note that the pressure adjustment should not exceed 0.8MPa (low pressure) and 1.2MPa (high pressure).

Adjustment Method of Semi-Automatic Control Pressure Regulator

Loosen the lock nut left, then tighten the pressure adjusting nut to the right, the pressure increases, the opposite direction of the loosening will reduce the pressure, adjusted to the required value, then the lock nut right fixed.

Adjustment of Pressure Control System for Fully Automatic and Semi-Automatic Models

Close the ball valve under the pressure regulator to use as a fully automatic model, and open the ball valve under the pressure regulator to use as a semi-automatic model. When adjusting, it should be noted that the set pressure of the pressure switch should be 0.05MPa higher than the set pressure of the pressure regulator.

The air compressor parts system is used to provide a low-pressure, high-flow air source for the production process. In the past, due to the manual control room noise is too loud, the operator can not stay long, a little inattention, the outlet temperature of the air compressor parts will exceed the standard, this parameter is particularly important to the chemical production process, poor control may cause defective products or even scrap, so that production costs increase; more importantly, sometimes the air compressor parts will occur wheezing, in serious cases will make it damaged. Therefore, in order to ensure the quality of products and protect the compressor parts system, there is an urgent need for a set of microcomputer automatic control system to control the compressor parts and manage the production. The structure of automatic control system of air compressor parts is complex, with high and low pressure circuit (air compressor parts are driven by 6 kV high pressure motor), gas circuit (two-stage booster), oil circuit, water circuit, etc. The working condition of air compressor parts is severe, strong electromagnetic interference, high vibration and noise, long working time, many input parameters, and there are 5 interlocking mechanisms, two closed-loop control, and its control is relatively complex. The system control process requires the compressor parts to run continuously without stopping, so the reliability of continuous operation and anti-interference ability of the system must be fully considered; the continuous operation should prevent the compressor parts from entering the boundary of wheezing, and it can exit soon after entering, so the control model should be accurate and the control parameters can be modified at any time with the season and process changes. The control principle of the system is that all working conditions are automatically controlled by the microcomputer except for the start-up and normal stopping of the air compressor parts, such as the automatic control of the three systems of air, oil and water circuits of the air compressor parts system and the axial displacement of the air compressor parts. Among them, the core control is the automatic control of anti-surge system of air compressor parts and export temperature. This is the key to ensure the safe work of air compressor parts and product quality. At the same time, the manual operation function of the original compressor parts is retained, so that even if the microcomputer system fails, it can still be operated normally by manual operation.

The automatic control system of anti-surge system can be considered as a system composed of inlet pipeline, centrifugal impeller of air compressor oil and exhaust pipeline. First of all, it takes a total control body, then the force acting on the control body is a continuous distribution of axial force (it includes the blade force and wall force), the energy exchange between the control body and the outside world is a continuous distribution of mechanical work W and heat Q. The mass exchange between the control body and the outside world (excluding the import and export sections) is expressed by a continuous distribution of flow. Air compressor parts are reciprocating intermittent air supply, with high airflow pulsation during operation, high compressor speed, smooth air delivery and no airflow pulsation, which can meet the needs of users requiring high air volume. There is basically no automatic control system for air compressor parts, and the compressor has a perfect automatic control and protection system, which is a mechatronic product, which facilitates the maintenance and management of the equipment, and also minimizes the energy consumption.
