The whole machine is skidded. The main and auxiliary machines are installed on the same skidded block, which has high safety.▲Compressor structure: V-type, 2-row, two-stage compression. The machine has the characteristics of low energy consumption, low noise, small starting torque, low vibration, high reliability, high degree of automation, easy operation and maintenance, etc.▲Motor: YB series explosion-proof motor is adopted, and the starting mode is explosion-proof soft start.▲Compressor cylinder lubrication mode adopts oil-free lubrication design, oil-free lubrication operation, piston rings, fillers and cylinders have longer service life and superior economy.▲Compressor is driven by explosion proof motor, and motor and compressor are directly connected by elasticity.▲Compressor cooling mode adopts air cooling.▲There is an air inlet buffer filter recovery tank to ensure that there is no natural gas leakage during operation and shutdown.▲Equipped with PLC explosion-proof soft start control cabinet.▲Manual reflux device is installed to ensure that automatic no-load start-up and change-over are operated under light load. .▲Compressor Configuration and Performance1. There is a ball valve in front of the entrance of the compressor.2．Safety valves are installed at all levels and intake air. When the pressure exceeds the standard, unloading is opened, and safety release system is equipped to ensure the safe operation of the system. The compressor field is equipped with a primary instrument to display pressure and temperature.3．The pry body is equipped with an exhaust gas recovery tank to start the compressor without load and improve the gas utilization rate.4.The waste oil and gas of the compressor are separated into two pipelines for centralized discharge.5．Instrument display system adopts electronic system.6．ESD Emergency Button: There is an ESD Emergency Button on the pry of the compressor. When an emergency occurs, the compressor will stop automatically after pressing the button.7．Acousto-optic alarm and shutdown settings for compressor chainl Compressor automatic start-stop, if the suction pressure too low or too high controll Alarm shutdown for high exhaust pressure of last stagel High exhaust temperature alarm shutdown at all levelsl Oil temperature low automatic heating, oil temperature high alarm shutdownl Oil pressure low alarm shutdownl Overload of main motor, oil pump motor and fan motor l ESD emergency shutdown button activation 8．Compressor Control System8.1The control system is composed of explosion-proof Siemens PLC soft start control cabinet.8.2Compressor uses imported Siemens PLC to complete the main logic control function, equipped with transmitter.8.3Compressor pry is equipped with a high-pressure interface.8.4Compressor inlet and exhaust pipe joints are connected to the outside of compressor pry block and matched with relevant joints to facilitate on-site installation.三Quality Assurance3.1Performance AssuranceCompressor shaft power deviation is not more than 5%; displacement deviation is not more than 5%; exhaust pressure has no negative deviation; other indicators should meet the relevant national regulations.3.2 Design Life of Compressors and ComponentsCompressor design life not less than 20 years;Mainland mainframe is guaranteed for 1 year (excluding spare parts)The service life of piston rod, piston, cross pin and cross head is not less than 5 years.The service life of piston ring, supporting ring, packing, oil scraper ring, valve disc and valve spring is not less than 6000 hours.3.3Quality Assurance PeriodThe warranty period is 12 months after leaving the factory. During the guarantee period, if parts are damaged due to design and manufacturing quality problems, the manufacturer is responsible for free replacement.3.4After-sales Service CommitmentQuality service is the eternal goal of Keepwin Technology Hebei Co., Ltd. The company wholeheartedly provides pre-sale, in-sale and after-sale services for new and old customers, and makes the following service commitments;3.4.1The Customer Department of Keepwin Technology Hebei Co., Ltd Co., Ltd. receives customer calls, letters, visits and other repairs information.
