Product Description

Product Description

MVR, or Mechanical Vapor Recompression, is a groundbreaking energy-saving technology designed to significantly reduce the need for external energy. It ingeniously harnesses the power of secondary steam energy that it itself generates, facilitating a cycle of energy reutilization. At the heart of this technology lies a brilliant principle: the secondary steam produced by the evaporator is subjected to compression through a high-efficiency steam compressor. This process masterfully transforms electrical energy into thermal energy, resulting in an increase in both the pressure and temperature of the secondary steam. The elevated temperature steam is then reintroduced to the evaporator, where it acts as a heat source, initiating material heating and further evaporation. This cycle not only optimizes energy use but also achieves the effective recycling of the latent heat of vaporization of secondary steam.
The DML series low temperature rise steam compressor stands as a pinnacle of engineering excellence, primarily comprised of several integral components. These include the meticulously designed compressor body, which encompasses the volute, impeller, main shaft, bearing housing, and seal, among others. In addition to these, the system integrates a robust coupling, a powerful motor, and a sophisticated array of electric instruments. Each component is expertly crafted to ensure seamless operation and superior energy efficiency, making this compressor an indispensable asset in the realm of cutting-edge energy solutions.

Installation Instructions

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/cm
2).
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;

Energy Efficient Low Temperature Rise Fan with Guide Vane Adjustment
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 ancillary equipment have been meticulously installed and the concrete foundation has fully solidified, it's time to initiate the compressor operation test. This crucial step ensures optimal performance and reliability, confirming that everything is perfectly aligned for your Energy Efficient Low Temperature Rise Fan with Guide Vane Adjustment.
3.3.8 The electric control cabinet, a vital hub for the compressor's operation, should be strategically installed within a convenient 5 meters of the compressor. For seamless integration, the wiring from the compressor to the electric control cabinet must be expertly connected using threading pipe, discreetly routed underground. Once the electric control cabinet is securely in place, ensure that the wiring terminals are carefully connected to the lines at the remote DCS, thereby establishing a flawless communication network for your cutting-edge fan technology.
