Title: Method for operation of the liquid cooling system of the internal combustion engine
Inventor: KROKHTA GENNADIJ MIKHAJLOVICH
IPC: F01P3/02
Filed: 2021-02-12
Granted: 2021-12-23
Abstract: FIELD: engine technology.  
     SUBSTANCE: invention can be used in liquid cooling systems designed for pre-start preparation of internal combustion engines for start-up. The method for operation of the liquid cooling system of internal combustion engines consists in the fact that the coolant is circulated through the cavities of the cylinder head (3), cylinder block (16) and cooling radiator (8) using a liquid pump (9) and pipelines. The coolant flows are controlled using thermostats (2), (17). The coolant is heated during pre-start preparation using a pre-start heater (1) and the coolant temperature is measured using a temperature sensor (6) installed in the cylinder head (3). During the pre-start thermal preparation of the engine, the drive of the main liquid pump (9) is switched off using an electromagnetic coupling (10). Coolant circulation is carried out only in the cavity of the cylinder head (3) using an autonomous liquid pump with an electric drive. When the maximum permissible temperature in the head (3) of the unit is reached, the preheater (1) is turned off and the engine is started. If, during engine operation, the liquid temperature in the head (3) of the block reaches a preset maximum value, the drive of the autonomous liquid pump is simultaneously switched off and the drive of the main liquid pump (9) is switched on, which simultaneously circulates the liquid through the cavities of the head (3) of the block and the block (16) of the cylinders. With a further increase in the temperature of the liquid, the coolant is circulated through the cooling radiator (8) and, if necessary, the cooling fan (26) is turned on. When the temperature of the liquid in the head (3) of the unit decreases below the set minimum value, the cooling fan (26) is first turned off. If the temperature of the liquid continues to decrease, then the cooling radiator (8) is turned off. With a further decrease in the temperature of the liquid, the drive of the main liquid pump (9) is simultaneously switched off and the drive of the autonomous liquid pump is switched on.   
     EFFECT: reduction of energy costs and time for pre-start thermal preparation as well as hazardous emissions into the atmosphere.

Abstract: FIELD: building demolition.  
     SUBSTANCE: invention relates to the field of demolition of structures, namely to the dismantling of chimneys. Mechanization of dismantling is provided, work is carried out without rope access, which ensures safety at any time of the year under suitable weather conditions. It also ensures that the machine is placed on one wall of the chimney without covering the entire chimney cut. This even makes it possible for chimneys with a large diameter of several meters to have a compact machine for dismantling the chimney. In addition, the speed increases and the complexity of moving the machine between the points of its stop for dismantling the chimney section decreases. The machine has a spatial support structure that includes two U-shaped frames connected on the sides, respectively, by a central rack and an insert. The frames are installed on the sawn-off wall of the chimney trunk and have internal stops for pressing against the wall of the dismantled chimney. A boom with a winch is fixed on the central rack, which deviates sideways from the first frame. A frame with a hydraulic hammer is suspended from the boom on cables. A hydraulic displacement cylinder and a chain are fixed to the support structure, covering the chimney wall through the upper edge and capable of moving the machine along this wall.   
     EFFECT: solving problem of reducing the dimensions of the machine and simplifying its movement through the chimney while dismantling.
