Introducing the groundbreaking MVR technology—Mechanical Vapor Recompression—a revolutionary energy-efficient solution designed to significantly curb external energy usage by harnessing the power of secondary steam energy. At the core of its ingenious operation, this cutting-edge technique involves the compression of secondary steam, generated by the evaporator, utilizing a high-efficiency steam compressor. This process ingeniously transforms electrical energy into thermal energy, elevating the pressure and temperature of the secondary steam. Subsequently, this enhanced steam is cycled back to the evaporator to heat materials and induce evaporation, effectively recycling the latent heat of vaporization. Experience a marvel in sustainable technology that not only optimizes energy usage but also promotes environmental responsibility.
Explore the DM series Single-stage Geared Steam Compressor, a masterpiece of engineering that embodies efficiency and reliability. This advanced compressor system is composed of a robust compressor body, a precise coupling, a durable gearbox, a sophisticated lubrication system, a powerful motor, an integrated electric instrument, and an advanced anti-surge control system. Its design is a testament to innovation, boasting a compact structure that ensures ease of maintenance and unrivaled operational convenience. Elevate your operations with a system engineered for performance and longevity.
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 and its supportive equipment, and after the concrete has fully cured and solidified, the stage is set to initiate the compressor operation test. This marks a pivotal moment in ensuring the system's efficiency and reliability.
3.3.8 It is imperative that the electric control cabinet for the compressor be strategically placed within a 5-meter radius of the compressor itself. The wiring should be carefully laid using threaded pipes that run underground, ensuring a clean and unobtrusive setup. Once the electric control cabinet is positioned, seamlessly connect its wiring terminals with the remote DCS lines to guarantee smooth and efficient operation.
