Embodiment 1

[0021] Such as Figure 25 As shown, the high-efficiency and energy-saving two-stage screw air compressor control system includes a frequency converter 69, an air compressor host 7, a motor 3, two temperature sensors, two pressure control devices, a controller 70, an oil-gas separator 26, a Heater 14, its operating steps are as follows:

[0022] (1) Start the air compressor, and the inverter starts to drive the motor;

[0023] (2) The motor drives the host to run according to the output of the frequency converter;

[0024] (3) The controller detects the status of each point of the air compressor at all times through the action of the sensor;

[0025] (4) One pressure control device detects the intermediate pressure under the primary host, and the other pressure control device detects the exhaust port pressure;

[0026] (5) One temperature sensor detects the exhaust port temperature of the primary main engine, and the other temperature sensor detects the exhaust port temperat...

Embodiment 2

[0041] Such as Figure 11 As shown, the difference between this embodiment and Embodiment 1 is that the bottom surface of the air compressor case 1 is provided with an air compressor base 58 and a motor base 60, and the air compressor base 7 is installed on the air compressor base 58 , the bottom of the motor 3 is provided with a mounting base 71, the mounting base 71 is installed on the motor base 60, the length of the motor base 60 is greater than the length of the mounting base 71, and the air compressor host 7 is installed on the air compressor base 58 by bolts , the mounting seat 71 is installed on the motor base 60 by bolts, and the installation is more convenient; in addition, the length of the motor base 60 is greater than the length of the mounting seat 71 of the motor 3, and when the motor 3 needs to be removed for maintenance or maintenance, the motor 3 can be installed in the Move on the motor base 60, the motor 3 is still shelved on the motor base 60, without havi...

Embodiment 3

[0043] Such as Figure 18As shown, the difference between this embodiment and Embodiment 1 is that the oil-gas separator 26 includes a barrel body and an oil mark 41, the upper end cover of the barrel body is provided with an upper cover A42, and the bottom of the barrel body is connected with an oil mark lower connection pipe 43, and the lower part of the barrel body The side wall is connected with an oil standard upper connection pipe 44, the oil standard upper connection pipe 44 and the oil standard lower connection pipe 43 are connected with the oil standard 41, the oil standard upper connection pipe 44 and the oil standard lower connection pipe 43 are connected with the oil standard 41 by bolt A45, the upper The edge of the cover A42 and the upper end of the staving pass through the rotating shaft A46, and the upper cover A42 and the staving are connected by a fixing bolt A47. A lower bracket A48 is arranged on the upper part of the outer side wall of the staving, and the ...

Abstract

The invention relates to the technical field of screw air compressor energy saving, in particular to an efficient energy-saving dual-stage screw air compressor control system. The efficient energy-saving dual-stage screw air compressor control system comprises a frequency changer, air compressor main machines, a motor, two temperature sensors, two pressure control devices, a controller, an oil-gasseparator and a heat exchanger; a first-stage main machine exhaust port temperature sensor is used for protecting an oil way system and the running condition of the first-stage main machine, a second-stage main machine exhaust port temperature sensor is used for protecting the whole temperature and running condition of the system, a first-stage main machine exhaust port pressure control device isused for controlling the middle pressure between the two stages of main machines, the main machine system is maintained at the best efficiency point, a second-stage main machine exhaust port pressurecontrol device is used for controlling the exhaust pressure of the system, the rotating speed of the frequency changer is controlled, and the appropriate gas yield is adjusted. The efficient energy-saving dual-stage screw air compressor control system has the beneficial effects that the problem about the temperature of two stages of compressors is solved, and the energy-saving efficiency of the two stages of compressors is improved.

Description

technical field [0001] The invention relates to the technical field of energy-saving screw air compressors, in particular to a high-efficiency energy-saving two-stage screw air compressor control system. Background technique [0002] Compressors are now widely used in many fields. The existing screw air compressors are complex in design and have a lot of pressure loss, and there are major hidden dangers of low-temperature heat transfer in the early stage of equipment use. In order to be able to monitor comprehensively, it is necessary to Control and adjust the usage scenarios from time to time to avoid the lack of intelligent control of equipment, high resource consumption and waste of energy, which is not conducive to energy saving and environmental protection requirements. Contents of the invention [0003] In order to solve the above-mentioned technical problems of avoiding high resource consumption and wasting energy due to lack of intelligent control of equipment, the...
