Salient Features of TMVT Compressors:

• TMVT make Twin Lobe Compressors (MTLK / MP / ETP Series) are enjoying tremendous reputation in the market since about 3 decades.
• Complete range of 18 Models of MTLK type covers requirements of various industries of divers nature.
• Suitable for different pressure up to 1 Kg/cm2 in Single Stage and up to 2.2 Kg/cm2 in Double Stage. Also suitable for Gas Duty as well as Vacuum Duty (Up to 600 mbar).
• Blower : The Main Body, Side Covers are manufactured from Graded Cast Iron as per CI IS 210 FG 260. Castings are procured from Foundries of repute like Bhagwati Spherocast, Ductile Iron Foundry, etc. etc.
• Rotors : The Rotors are of S. G. Iron as per grade 400 / 015 of smaller capacities up to 1500 M3/ Hr. For larger capacities of Twin Lobe Compressors, Rotors are having Lobes in Graded Cast Iron IS 210 FG 260 Construction. All types of Rotors are with EN-8 Shafts.
• For corrosive gases we supply blower in C.I. construction with electro less nickel plating on contact parts or complete blower in stainless steel construction.
• Machining : All components are machined to very accurate dimensions with extremely tight tolerance with guaranteed interchangeability. The Castings of Casing and Main Covers (Bearing Housing) are stress relieved after pre- machining for dimensional stability at elevated temperature.
• Lobe Profiles : The Lobes of Rotors are having involute profile ensuring Uniform clearances between rotor to rotor in any position of two rotors. The profile also ensures uniform clearances between Casing and Lobes unlike providing PTFE strips which is usually done as a cheap method of manufacturing for maintaining clearances.
• The Rotor profiles are machined on CNC machines and imported Copy Shaping/Planning Equipment ensuring profile with high accuracy/finish which result in power saving.
• MTLK type blower main chamber is sealed by labyrinth seal. Four numbers piston rings are fitted on each side of rotor.
• Lubrication : Both side of side casings are oil filled. All bearings and gears are splash lubricated. This increases life of bearings and gears.
• Timing Gears : The Timing Gears are wide for more load bearing, and having helical teeth, hardened and ground, maintaining backlash within the limit of 0.03 to 0.06 mm to ensure low noise level. Same are either Press-fit on rotor shafts by Tensioning Element or having taper locking on rotor shaft by hydraulic system making mounting and dismounting of Gears much easier.
• Bearings : In case of Air Cooled Compressors model MTLK, Bearings on the drive shafts have Spherical Taper Roller Bearings to take axial as well as thrust load whereas the gear Shafts have Angular contact Ball Bearings. In case of Water Cooled Compressors Model MP, all bearings are cylindrical Roller Bearings.
• Cooling : .Air Cooled as well as Water cooled models are available for specific requirements .In case of air cooling, housing surface is cooled by convection cooling. Making fins on the housing surface increases convection. In case of Water Cooling, water is flown in the casing constantly at the specific rate which cools the blower, lobes and oil..
• Testing : All the Blower are individually tested with Test Procedure based on IS-10431/IS-5456-Rev. (BANGALORES-726/BS-1571-Part-II-Rev) for capacity, power consumption, temperature rise noise level as well as vibration level.

Three Lobe Roots Blower :

TMVT Three Lobe Roots Blower are new 3MTL series Roots type Blower. Rotors are manufactured on high precision CNC machines ensuring high performance. Owing to ‘THREE LOBES' Rotor design, the reverse flow pressure variation period is only 2/3 of that of a conventional ‘TWO LOBES' rotor, the peak pressure is also lower. So the noise and pressure pulsation are greatly limited.

Features Of Three Lobe Roots Blower :

• Discharge pressure pulsation is reduced, so lighter loading of bearings and timing gears ensures the long servicing life.
• Oil Chamber is separated from main chamber. Hence air is oil free.
• Bearings on drive and driven sides are lubricated by oil
• Construction simple and hence easy maintenance.
• Less back flow. Hence Volumetric Efficiency increased.
• Stable air flow rate
• Lower vibration. Less vibration transmitted through the lobe results approximately 20% longer bearing life
• Three lobes design efficiently reduce noise by approximately 5dB

Product Details:

Air Roots Blowers offered by us have less pulsation, less vibration, less noise resulting into longer life of the machines compare to Two Lobe Blowers.  Also in our Tri Lobe Blower’s design, we have separated both sides bearing housings and oil chambers from main working chamber and due to this design possibility of entering moisturized and dusty air into the bearings and oil chambers is eliminated which increases life of bearings and subsequently other rotating parts of the machine.
