Abstract

The invention allows to increase the efficiency of the pump. A partition 12 with a central bore 13 having a seal for the rod 11 is installed between the dividers 6 and 10 to form an additional pump chamber 14 with valves 15 and 16. The capillary-porous evaporator 7 and the condenser 8 filled with partially boiling driving medium are made spherical in place of 17 mutual contact. The evaporator is located on the end wall 9 of the housing 1 in the zone circumferentially bounded by its contact with the condenser. The spacers 6, 10 are bonded with a membrane and made in the form of membranes. This embodiment provides a double pump action and reliable contact of the evaporator and condenser on spherical surfaces, which increases the rate of condensate absorption and prevents leakage of a pair of boiling medium to the cooled wall 19 at the site of contact. 1 hp f-ly ,. 1 il.

The invention relates to pumping engineering, concerns heat driven pumps and can be used in various industries for pumping fluids.

The aim of the invention is to increase the efficiency of the pump.

The drawing shows the pump.

The pump includes a housing 1, in which a flexible separator 6 is installed to form a pump chamber 2 with valves 3 and 4 and a drive chamber 5. A capillary-porous evaporator 7 and a condenser 8 filled with partially light-boiling drive medium and condenser 8 are mounted in the drive chamber 5 and connected respectively with a top wall 9 of the housing 1 and a flexible separator 6.

The pump is additionally equipped with a second separator 10 connected to the first separator 6 by the rod 11. In case I, a partition 12 is made with a central bore 13 having a seal (not shown) for the rod 11, installed between the separators 6 and 10 to form an additional pump chamber 14 with valves 15 and 16, the Evaporator 7 and the condenser 8 are spherical in the place of the mutual contact 17. When this evaporator 7 is located on the end wall 9 of the housing 1 in the area bounded on the periphery of the site 17 of its contact with the capacitor 8. The separators 6 and 10 are made in the form of membranes. Valves 3 and

15 are suction and valves 4 and

16 under pressure. At the inlet, the pump has a filter 18. The wall 19 of the housing is cooled.

When the upper end wall 9 of housing 1 is heated by solar radiation, bring heat to the capillary-porous evaporator 7, in the pores of which there is a boiling driving medium. The latter evaporates, the vapor pressure in the actuator 5 increases, and the separator 6 sags down, dragging the separator 10 connected with it by the brush 11 (see the left half of the drawing). At the same time, the pumped medium through the discharge valve 4 is forced out of the pump chamber 2 to the consumer, and the pumped medium is sucked from the source through the suction valve 15 into the pump chamber 14.

When the separators 6 and K) are moved downward, the capillary-porous capacitor 8 moves away from the charger 7, and the EJ at the contact place 17 forms a gap, through which the pairs of low-boiling medium rush towards

cooled by the pumped medium wall 19 of housing 1 and condensing on it. The condensate is absorbed by the condenser 8. At the same time, by drying the evaporator 7 and condensing the vapor of light boiling medium, the pressure in chamber 5 drops, and the separators 6 and 10 rise (right half of the drawing) due to its elasticity. The condenser 8 comes into contact with the evaporator 7, thereby blocking, in the place of contact 17, leakage of the light boiling medium to the cooled wall 19 of the housing 1. At this time, the condensate from the condenser 8 is absorbed into the evaporator 7, which is saturated with light boiling liquid. In the process of lifting the dividers 6 and I), the pumped medium is sucked into the pump chamber 2 through the suction valve 4 and the pumped media is displaced to the consumer through the pressure valve 16 from the pump chamber 14.

Thereafter, evaporation of the boiling medium in the evaporator begins again, and the cycle is repeated.

By providing double operation of the pump and reliable contact of the evaporator 7 and condenser 8 on spherical surfaces, which increases the speed to draw in condensate, the efficiency of the pump is increased.
