MVR, which stands for mechanical vapor recompression, represents an innovative energy-conserving technology designed to significantly curtail the need for external energy sources. It achieves this by ingeniously reutilizing the secondary steam energy it generates. The fundamental principle at work is that the secondary steam produced by the evaporator is then efficiently compressed using a high-performance steam compressor. This process smartly converts electrical energy into thermal energy, resulting in an elevation of both the pressure and temperature of the secondary steam. The heated secondary steam is then seamlessly cycled back to the evaporator, where it effectively heats the materials, inducing further evaporation. This elegant cycle allows for the brilliant recycling of the latent heat of vaporization inherent in the secondary steam, delivering both environmental and cost benefits.
The DM series Single-stage geared steam compressor is an engineering marvel that primarily encompasses a compressor body, coupling, gearbox, lubrication system, motor, electric instrumentation, and an advanced anti-surge control system. Its design is characterized by a remarkably compact structure that ensures not only seamless integration but also enhanced ease of maintenance. This compressor series is meticulously crafted to cater to the demands of cutting-edge industrial applications, offering a reliable and efficient solution for those seeking superior performance in steam compression technology.
3.3.1 The compressor base is integrally placed on the foundation, put wedge-shaped shim under the base (used to adjust the unit level),
place two wedge-shaped irons alternately, after leveling the unit, and spot weld the wedge-shaped irons for 4~5 points. The wedge shall be
manufactured and installed by the user according to the actual situation, and the contact surface shall be finished (even contact of inclined
plane, and the bearing capacity of wedge iron shall not be greater than 40Kg/cm2).
3.3.2 Use a level to find the level. The leveling requirements of the unit: the axial level of the unit is 0.05/1000mm, and the horizontal
level of the unit is 0.10/1000mm.
3.3.3 Coupling is centered. Before starting alignment, confirm the following requirements:
1) Turn off the main power supply;
2) Remove the coupling shield;
3) Remove the diaphragm coupling intermediate section;
4) Check the flatness of the motor installation plane to ensure that there are no stolen goods, dirt and attachments;
5) The motor bolt hole should be larger than the bolt size, so that the bolt can be loosened to adjust the motor;
6) Prepare enough stainless steel gaskets to cover the foot of the motor, the gaskets should not have attachments and should be flat enough. You cannot use long and thin gaskets to insert between the motor and the base for adjustment;
7) Use a dial indicator or a laser alignment meter with an accuracy of 0.01mm (prepared by the customer himself);
8) Prepare the bracket for supporting the dial indicator as shown in the figure below;
9) The motor wheel hub mounting bracket is used for mounting a dial indicator on the edge of the wheel hub, and placing a dial indicator probe on the outer edge of the compressor wheel hub;
10) By adjusting the adjustment bolts around the motor feet, the compressor and the motor center line are basically on the same line (or according to the corresponding instructions), and the maximum deviation of the outer circle is 0.05mm (the motor shaft center line should be higher than the compressor low-speed shaft center line), coupling end face 0.03~0.05mm;
11) Finally, tighten the motor foot bolts, and review the outer circle runout and end face runout of the coupling;
12) Install the coupling intermediate section after the motor idling test.
3.3.4 After adjusting the "levelness" and alignment of the casing, tighten the anchor bolts. After the mechanical operation (or trial operation), loosen the bolts and tighten them again.
3.3.5 The impeller is a high speed rotating component, and any solid or liquid entering impeller will cause irreversible damage to compressor. Therefore, it is necessary to ensure that the inlet and outlet pipelines connected with compressor are clean and meet the requirements of steam corrosion grade of the system. Pipelines that do not meet this condition must be rectified. It is suggested to add solid liquid separation equipment (gas scrubber or sedimentation tee) before the straight pipe at the compressor inlet.
3.3.6 Install compressor inlet and outlet pipes. Import and export pipelines shall be installed with relevant pipeline accessories according to PI diagram. The pipeline connected to the compressor shall be supported by another bracket, and its weight shall not be supported by the compressor body.
3.3.7 Following the meticulous installation of the main fan along with its essential ancillary equipment, and once the concrete foundation has fully solidified, you are ready to initiate the compressor operation test. This pivotal step ensures everything is in perfect working order, setting the stage for optimal performance and reliability of the system.
3.3.8 Position the electric control cabinet for the compressor within a convenient distance of 5 meters from the compressor itself. Ensure the connection from the compressor to the cabinet is seamlessly integrated by using a threading pipe, which is skillfully routed underground. Once the cabinet finds its rightful place, proceed to connect the wiring terminals inside the electric control cabinet to the lines at the remote DCS. This strategic connection guarantees a smooth and efficient operation, reflecting the precision and innovation of NANTONG DART-RICH FAN CO.,LTD.
