MVR, an acronym for mechanical vapor recompression, stands as a groundbreaking energy-saving technology. Its brilliance lies in its capacity to significantly cut down external energy consumption through the ingenious reuse of secondary steam energy. The core principle revolves around the secondary steam produced by the evaporator, which is then subject to compression by a high-efficiency steam compressor. This process ingeniously transforms electrical energy into thermal energy, elevating both the pressure and temperature of the secondary steam. Consequently, this heated steam returns to the evaporator, effectively heating the materials and sparking evaporation anew. This entire cycle masterfully recycles the latent heat of vaporization from the secondary steam, showcasing unparalleled efficiency and sustainability.
The DML series low temperature rise steam compressor is a marvel of engineering, crafted with precision and sophistication. It consists chiefly of a robust compressor body, including crucial components such as the volute, impeller, main shaft, bearing housing, and seal. In addition, it is equipped with a coupling, motor, and an array of electric instruments, each contributing to its seamless operation and reliability. This meticulous assembly ensures the DML series delivers exceptional performance, meeting the demands of modern industry with ease.
3.3.1 Begin with the seamless placement of the compressor base on its sturdy foundation. To ensure impeccable unit leveling, strategically insert wedge-shaped shims beneath the base.
Thoughtfully alternate the placement of two wedge-shaped irons. Once the unit achieves level perfection, secure the shims by spot welding them at 4 to 5 points.
This precision task, including the crafting and installation of the wedge, falls to the user, tailored to meet specific needs. The contact surface must be flawless,
ensuring an even conjunction of inclined planes. Note, the bearing capacity of the wedge iron must not surpass the remarkable threshold of 40Kg/cm2).
3.3.2 Utilize a precision level to determine the exact level. The stringent leveling criteria for the unit are as follows: the axial level must hold at 0.05/1000mm,
while the horizontal level also adheres to a meticulous 0.10/1000mm.
3.3.3 Master the art of coupling alignment! Prior to embarking on this alignment journey, validate the following crucial prerequisites:
1) Ensure the main power supply is safely turned off;
2) Carefully remove the shielding of the coupling;
3) Detach the diaphragm coupling’s intermediate section with care;
4) Scrutinize the flatness of the motor installation plane, ensuring it remains free of any debris or contaminants;
5) Ascertain that the motor bolt hole is generously larger than the bolt size, allowing for loosening, thereby facilitating effortless motor adjustments;
6) Arm yourself with ample stainless steel gaskets to adorn the motor's foot. The gaskets should be pristine, flat, and devoid of attachments. Avoid using elongated or thin gaskets for base adjustments;
7) Equip yourself with a dial indicator or a laser alignment meter, boasting an accuracy of 0.01mm (to be procured by the customer);
8) Ready the bracket designed to support the dial indicator, as demonstrated in the illustrative figure below;
9) Utilize the motor wheel hub mounting bracket to deftly mount a dial indicator on the hub's edge. Place the dial indicator probe on the compressor wheel hub's outer edge;
10) With finesse, adjust the bolts around the motor feet to align the compressor and motor center line harmoniously. The outer circle deviation must not exceed 0.05mm,
and ensure that the motor shaft center line is elevated above the compressor's low-speed shaft center line, maintaining a coupling end face between 0.03 and 0.05mm;11) Conclude by securely tightening the motor foot bolts, and meticulously verifying the outer circle runout and coupling end face runout;
12) Seamlessly reinstall the coupling intermediate section post motor idling test.
3.3.4 Post adjustment of both the casing's 'levelness' and alignment, ensure the anchor bolts are firmly tightened. Post mechanical operation, loosen and re-tighten for optimal security.
3.3.5 The impeller, a high-speed marvel, must remain pristine. Any solid or liquid intrusions can inflict irreversible harm to the compressor. Thus, ensure inlet and outlet pipelines are spotless,
3.3.6 Meticulously install inlet and outlet pipes, adhering to the PI diagram for relevant pipeline accessories. Ensure the pipelines are supported independently with a robust bracket, avoiding weight on the compressor.
3.3.7 With the main fan and ancillary equipment fully installed, and concrete perfectly cured, it's time to embark on the exhilarating compressor operation test.
