Abstract
The utility model relates to a capacity regulating device which serves the chemical industry gas, such as coal gas, natural gas, etc. as a working medium, and is arranged at the inlet position of a centrifugal type pressurizing machine. The capacity regulating device is provided with a line of fixed blade cascades and a line of movable blade cascades. According to the requirement of the working condition, via a variable geometry flow channel established by the rotation of the blade cascade, the non-stage regulation is carried out on the gas flow and the gas pressure of the pressurizing machine. The capacity regulating device has two functions; the positive pre-rotating regulation has the function of infinitely reducing the flow capacity of the pressurizing machine, and the negative pre-rotating regulation can cause the parameter of the rated output of the pressurizing machine to be increased by 15%-20%. The capacity regulating device implements the remote manual operation or self control; the pressurizing machine can be caused to save the power by 15%-20% on average, and the current of a motor is decreased, the service life of the motor is prolonged, and the surge of the pressurizing machine can be effectively prevented.
Description
The utility model relates to and a kind ofly carries out flow, pressure controlled novel regulating controller to flowing into chemical industry working medium such as coal gas in the press, natural gas.
Centrifugal gas compressor is a kind of of centrifugal blower, extensive use in China's gas plant, steel mill and chemical enterprise.The general power of press is many more than 100KW, and power is big, seal request is high, and variable working condition is many during operation, its regulation and control with energy-conservation be the emphasis that relevant department pays close attention to always.At present, domestic regulation and control work in this respect is still in the starting stage, and the measure of being adopted can be divided into two classes:
1) conventional valve regulated: at the import and export preparation gate valve or the butterfly valve of press, this type of regulates throttling resistance consumption
Very big, less economical.
2) speed change is regulated: between press and motor, install fluid coupling additional or carry out motor speed-regulating, and this
Though the adjusting method has energy-saving effect preferably, investment is big, installs and the maintenance expenses height.
The Standard Turbo-Air and MSG Guide Vane and the C8 SeriesInlet Guide Vane that abroad use now are with the controlling device that air is bad as the sealability of transferring working medium, flow passage component is coarse mostly, and its variable working condition adaptive capacity is poor and can not be used for the occasion of coal gas working medium.
The purpose of this utility model is by preswirl field control method, obtains that a kind of adjusting function is good, the resistance consumption is little, regulates that the degree of depth is big, simple installation, service-strong controlling device.If when being used for having now the unit transformation, press need not done any change.When doing variable working condition and regulating, pressure reduces synchronously with tolerance, but comparatively slow, can make press and extraneous demand fully adaptive, thereby satisfies the requirement of external load with rational capacity.
The purpose of this utility model is achieved in that by different movable vanes and turns to, and can form with the press impeller and turn to consistent flow field of just prewhirling (being applicable to conventional variable working condition adjusting) or the negative flow field (being applicable to the special adjusting to the press dilatation) of prewhirling.The utility model comprises frame (1), inner housing (9) and the outlet end cap (10) of controlling device, static cascade (2) and moving blades (4) that arranged radially is arranged in the inner housing (9), interior movable vane number of moving blades and width of blade are 2 times of stator blade, can do 0 °～135 ° revolution, the number of blade remains between 12～16, and blade profile is streamlined.
Along on the direction of flow of gas shown in the arrow, air-flow runs into the variable-geometry runner of being made up of static cascade of arranged radially (2) and moving blades (4), thereby after making air flow stream go out leaf grating, having strong spin feature, its rotation direction and intensity are by the angle of swing decision of moving blades intra vane.The gear train assembly control that the flow channel shape of moving blades is made up of gear mesh (6), gear ring (7) etc., this transmission system is driven by the output shaft of final controlling element (5), and final controlling element carries out artificial or operation automatically according to the signal variable of taking from the press output parameter.
This device is provided with multiple combination type black box (3), (8), in O shape circle and line cutting piston ring are arranged, O shape cast formula is selected by working medium character and temperature.
The utility model is simple in structure, compact, reliable operation, manual dexterity, can carry out manual or full-automatic remote-controlled, the various working condition requirements that its adjusting function can satisfy press economize on electricity more than 20% than the valve regulated mode under identical operating mode, and the function that prevents the press surge is arranged.
Shown in Figure 1 is gas compressor capacity regulating controller sectional arrangement drawing.
1 narrate embodiment of the present utility model in conjunction with the accompanying drawings: the utility model is made up of frame (1), static cascade (2), black box (3), moving blades (4), final controlling element (5), gear mesh (6), gear ring (7), black box (8), inner housing (9) and outlet end cap (10), and the shown position moving blades is in the standard-sized sheet shape.Final controlling element (5) places the device top to form compact operation mechanism.Its final controlling element (5) is accepted operational order (manual or automatic), driven gear rotates (6) and gear ring (7), and then drive moving blades (4) revolution that an end has the awl tooth, moving blades (4) can be done 0 °～135 ° revolution under instruction, thereby form the different positive and negative flow fields of prewhirling, reach the purpose of regulating flow and pressure.
Claims (2)
1. capacity regulating controller especially for centrifugal gas compressor ingress, it is characterized in that this device has one group of static cascade that is arranged radially (2) that places in the inner housing (9), one group of moving blades (4) that can change angle of swing is arranged thereafter, control the runner of moving blades (4) by the gear train assembly of gear mesh (6), gear ring (7) composition.
2. device according to claim 1 is characterized in that moving blades can do 0 °-135 ° revolution, thereby forms the positive and negative runner of prewhirling.The number of blade in the moving blades is the 12-16 sheet, and blade profile is streamlined.
