The thermal hydrodynamic pump consists
of: heat-generator, electric motor, joint box, frame. The
thermal hydrodynamic pump is equipped with control, measurement
and monitoring units. TS1-055/75/90/110 products are unified and
differ only in case details, mounting dimensions, and electric
motor capacity. |

Heat-generator is a cylinder with covers,
inlet and outlet fittings. The inlet fitting is at the bottom
part of the cover at the electric motor side, the outlet fitting
is at the top part of the heat-generator outside cover. A heat
carrier activator – rotor – made as a shaft with rigidly fixed
disks of a special profile is mounted in the case. The
heat-generator shaft is connected with the electric motor
through a joint box.
The shaft at the motor side is fixed with
a ball double-row self-aligning bearing, the international
marking (ISO 492) is 2311, Russian marking - 1611, and at the
other side - with 466311 duplex bearing.
End seals 60mm Ò2100/K/BR1C1/M manufactured by the John Crane
or analogous end seals by other manufacturers are mounted on the
shaft to prevent heat carrier leakage on the shaft. End seals
are cooled with heat carrier under pressure. |

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.
