Block heating substations for make-up for various closed systems using booster pumps

The independent circulation circuit is, as a rule, filled and replenished from the return pipeline of the vehicle, using make-up pumps.

The coolant from the TS return pipeline enters the make-up pipeline through ball valve No. 6. Further, it is cleaned of mechanical impurities with a mesh filter No. 5. The consumption of make-up water is recorded by meter No. 4. Then follows the “normally closed” solenoid valve #2, which opens in sync with the start of pump #1 and closes in sync with the stop of the pump. The pressure boosting pumps are turned on and off by a signal from the pressure switch No. 14 installed in front of the circulation pumps on the return pipeline of the heating / ventilation / other system. Pumping group, consisting of working and reserve booster pumps No. 1. To ensure the absence of vibrations and noise in the pipelines of the system, flexible connectors No. 12 are used. After the downstream pressure regulator No. 3, which maintains a constant pressure in the heating / ventilation system, the make-up pipeline is connected to the return pipeline of the heating / ventilation / other system.

Technical parameters of make-up BTP based on MHI (PN10) pumps.

Make-up BTP marking

TJ.MHI 205/PN10/2n/DN 25

TJ - BTP make-up

MHI 205 - brand of pumps

PN10 - design pressure, bar

2n - number of pumps

DN 25 - pipeline diameter

NOTES:

We reserve the right to make changes to the design of the BTP that do not affect the technical characteristics of the product.

Our specialists carry out an individual calculation of the BTP and its cost with initial parameters different from those indicated in the table.
