Introducing the revolutionary technology of MVR, which stands for mechanical vapor recompression—an ingenious energy-saving innovation designed to significantly cut down on external energy needs. This is accomplished through the remarkable process of reutilizing the secondary steam energy that it generates. The core principle behind this technology is both elegant and efficient: the secondary steam produced by the evaporator is cleverly compressed using a high-energy efficiency steam compressor. This process seamlessly transforms electrical energy into thermal energy, resulting in a rise in both pressure and temperature of the secondary steam. This transformed steam is then returned to the evaporator, where it efficiently heats the materials, leading to further evaporation. This cycle ingeniously recycles the latent heat of vaporization of the secondary steam, marking a paradigm shift in energy utilization.
Discover the exceptional DM series Single-stage geared steam compressor, a masterpiece of engineering excellence. This system is meticulously designed and comprises several premium components: the compressor body, a robust coupling, a state-of-the-art gearbox, a highly efficient lubrication system, a powerful motor, sophisticated electric instruments, and an advanced anti-surge control system. All of these are integrated into a structure that is not only compact but also engineered for ease of maintenance, making it both practical and reliable for any demanding industrial environment.
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 and its auxiliary components are expertly installed and the concrete foundation has reached full solidity, it's the perfect moment to proceed with the compressor operation test, ensuring a seamless and efficient performance evaluation.
3.3.8 The compressor's electric control cabinet should be strategically positioned within a convenient 5-meter radius of the compressor itself. The wiring pathway from the compressor to the control cabinet should be meticulously routed through threading pipes and situated underground to ensure safety and efficiency. Upon positioning the electric control cabinet, it is crucial to seamlessly connect the wiring terminals within the cabinet to the corresponding lines at the remote DCS, enabling flawless communication and control.
