If pressure at heat-generator outlet fitting is less than 2.0kgs/cm2, even at a short-term start-up of the product, it causes the end seals destruction.
Heat-generator does not generate outlet pressure. Moreover as the diameters of disks apertures and gaps between the heat-generator case and disks are the minimum, the pressure loss makes 1.2-2.0 kgs/cm2. Pressure in the heat system is generated by the circulating pump, which power is defined by its concrete design features. Product automatics are designed for control of the circulating pump with a power max. 5.5 kW. The circulating pump is not an equipment of the product and does not enter into the delivery complete set.
Serial, industrial, induction, three-phase electric motors with a short-circuited rotor, frequency of 50Hz, line voltage of 380V, rotational speed of 3000 rpm, on lugs, with one end shaft are applied for thermal hydrodynamic pumps. At the customer's option installation can be completed with electric motors in tropical, marine, explosion-proof, etc. modification.
Power of the electric motor is selected from the line by the rated capacity parameter – power necessary for starting spinup of the heat-generator. The rated capacity is necessary for initial spinup of the shaft with a large inertia moment, and overcoming of heat carrier viscosity in the heat-generator. As the motor gets an operating mode the power consumption decreases to 10%.
The joint box consists of two half-couplings connected with metal fingers with rubber spigots. Acceptable radial concentricity is max. 0.07mm.
The heat-generator and electric motor are delivered to the customer skid-mounted. The frame for TS1-055/75/90/110 products is unified and differs only in binding of mounting dimensions of heat-generator and electric motor. The frame is made of channel # 18. Frame outer dimensions (length/width): 2000mm x 700mm.
For maintenance of concentricity of the electric motor and heat-generator the frame is annealed, and then mounting faces are planar machined with a facer that eliminates deformation and heat stress in the frame coursed by welding.
The thermal hydrodynamic pump is installed on six vibratory bearings or special rubber mats in order vibration is not transferred to the base. Delivery hoses (flexible inserts) prevent transfer of vibration to the pipes of heating system.
