Impact on the lubrication system: 1. Decrease in lubricant viscosity: The viscosity of lubricants decreases as temperature rises. In high-temperature environments, lubricating oil becomes thinner, its lubricating properties decline, and it is difficult to form a thick enough oil film on the surfaces of the moving parts of the compressor. This leads to increased friction between the moving parts, thereby increasing wear and shortening the equipment’s service life. For example, insufficient lubrication between the crankshaft and the bearings can lead to overheating or even damage of the bearings. 2. Accelerated oxidation and deterioration of lubricating oil: High temperatures speed up the oxidation reactions of lubricating oil, causing changes in its components and the formation of harmful oxidation products such as sludge and varnish. These substances adhere to the surfaces of the internal components of the compressor, affecting their normal heat dissipation and lubrication functions. They can also block the oil passages, resulting in insufficient supply of lubricating oil and further increasing the risk of equipment failure. 2 Effects on the cooling system: 1. Reduced cooling efficiency: Reciprocating compressors generate a large amount of heat during operation, which needs to be dissipated through the cooling system. As the ambient temperature rises, the temperature of the cooling medium (such as cooling water or air) also increases accordingly. This reduces the temperature difference between the cooling system and the compressor, thereby lowering the cooling efficiency. For example, in the case of air-cooled compressors, high-temperature environments raise the temperature of the surrounding air, reducing the amount of heat that can be carried away by the air, which in turn leads to an increase in the exhaust temperature of the compressor. 2. Rising cooling water temperature: If the compressor uses a water-cooling system, the temperature of the cooling water will also increase in high-temperature environments. This reduces the amount of heat carried away by the cooling water, causing the temperatures of components such as the compressor cylinders and valves to rise, which affects their proper operation. At the same time, excessively high cooling water temperatures can also cause the dissolved oxygen in the cooling water to precipitate, leading to corrosion of the cooling system and affecting its service life. 3. Effects on compressor performance 1. Reduced displacement: Rising ambient temperatures lead to a decrease in the density of gases. At the same suction pressure and speed, the mass of gas drawn in by the compressor decreases, resulting in a reduced exhaust volume. This will affect the efficiency of the compressor, preventing it from meeting the requirements for gas flow during the production process. 2. Increased power consumption: Due to the reduced gas density, the compressor must exert more effort to compress the gas in order to achieve the same exhaust pressure. Therefore, an increase in ambient temperature raises the power consumption of the compressor, increasing the load on the motor, raising energy consumption, and increasing operating costs. 3. Increased failure rate of air valves: In high-temperature environments, components such as the springs and sealing elements of air valves are prone to thermal expansion, which leads to a decline in their sealing performance. At the same time, high temperatures reduce the elasticity of the springs in the gas valves and weaken the strength of the valve plates, leading to issues such as gas leakage from the valves and breakage of the valve plates, which affects the performance and reliability of the compressor. 4 Impact on equipment safety 1. Thermal expansion of components: The components of reciprocating compressors expand due to heat at high temperatures. If the expansion is uneven, it may cause changes in the clearance between components, and even lead to sticking, thereby affecting the proper operation of the equipment. For example, if the gap between the piston and the cylinder is too small, it may cause the piston to collide with the cylinder, resulting in equipment damage. 2. Equipment overheating: The temperature of the compressor rises due to factors such as reduced cooling efficiency and increased power consumption. If the equipment remains in an overheated state for an extended period, it may cause damage to its components, such as burned-out motors or deformed cylinders, and it could even lead to safety incidents like fires.
