MVR, or Mechanical Vapor Recompression, is a cutting-edge energy-saving technology that significantly reduces your need for external energy sources by ingeniously reusing the secondary steam it generates. This innovative process works by compressing the secondary steam, produced by the evaporator, using a highly efficient steam compressor. This compression process transforms electrical energy into thermal energy, elevating both pressure and temperature of the secondary steam. The result is a rise in temperature that propels the secondary steam back into the evaporator, where it heats materials and induces evaporation. Ultimately, this ensures a brilliant recycling of the latent heat of vaporization, optimizing energy use and efficiency in your processes.
The DM series Single-stage Geared Steam Compressor is a marvel of engineering, meticulously designed to incorporate essential components such as the compressor body, coupling, gearbox, lubrication system, motor, electric instrumentation, and an advanced anti-surge control system. This high-performance compressor boasts a compact structure, ensuring it is not only space-saving but also remarkably convenient for maintenance. Experience seamless operation and reliable performance with a design that emphasizes user-friendliness and minimal downtime.
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 Once the main fan along with its auxiliary components has been meticulously installed and the concrete base has fully solidified, you can proceed to conduct the compressor operation test. This crucial step will ensure optimal functionality and reliability of your system.
3.3.8 For seamless operation, the compressor's electric control cabinet should be positioned within a convenient 5-meter range from the compressor. The wiring that connects the compressor to this cabinet must be securely threaded through an underground piping system. Once the cabinet is properly situated, establish a connection by linking the wiring terminals inside the cabinet to the lines at the remote DCS, ensuring a streamlined and efficient setup.
