Abstract

Provided is a gas-oil balance type gas-liquid separation device. The gas-oil balance type gas-liquid separation device comprises a barrel, wherein a plurality of U-shaped pipes are arranged in the barrel, a first oil return hole is formed in the side face of the bottom of each U-shaped pipe, a second oil return hole is formed in the end of each U-shaped pipe, a baffle is arranged on a top cover of the barrel, and is used for preventing splashing liquid generated in the process of operation from entering the U-shaped pipes, and a gas inlet pipe is welded to the middle of the top cover. According to the gas-oil balance type gas-liquid separation device, due to the facts that the design of the U-shaped elbows is adopted, and the interiors of the U-shaped elbows are symmetrical, internal splashing is prevented, oil at the bottom of the separation device can be evenly distributed to compressors, the problem that when a system runs in a partial load mode, the flow velocity of refrigerants in a gas pipe is excessively low, so that the oil return capacity of the system is reduced is solved, the gas-oil balance type gas-liquid separation device is applicable to gas-oil balance when the compressors run in parallel, and safe reliability of operation of a heat pump/multi-union unit is greatly improved.

Description

Gas and oil balance-type gas-liquid separation device

Technical field

The utility model relates to a kind of separator, is specifically related to the gas and oil balance-type gas-liquid separation device that a kind of heat pump/multi-joint unit is used.

Background technology

At present, earth source heat pump unit, net for air-source heat pump units have been familiar with by people and are cognitive, and are widely used in the various places such as refrigeration, the office heating, factory building, hotel.And most source pump are while adopting 2 and above multi-compressor structure, usual way is that every compressor completes an independently closed circuit operation, and water piping system is public, in the time of certainly will causing so therein a loop works, cold water/the hot water producing mixes with the loop of not working, the temperature error of measuring is excessive, causes the compressor of work excessively to freeze, and affects the press life-span; Now, it is some that water route, public to change fluorine road into public, although guaranteed like this accuracy of temperature measurement, but caused again, do not suck the refrigerant quality of every compressor and lubricating oil not etc. when practical application, can cause so a wherein press oil starvation operation, finally cause card cylinder, burn, another oil mass is too much, has affected heat exchange efficiency.

Summary of the invention

The utility model provides a kind of gas and oil balance-type gas-liquid separation device, the poor problem of heat pump/multi-joint unit property safe and reliable to operation existing to solve prior art.

The utility model comprises cylindrical shell, solving the technical scheme that its technical problem adopts is that some U-shaped pipes are set in cylindrical shell, the bottom sides of U-shaped pipe arranges the first spill port, the tip position of U-shaped pipe arranges the second spill port, the top cover of cylindrical shell arranges baffle plate, in case the liquid that splashes producing when operation enters in U-shaped pipe, an air inlet pipe is welded in top cover centre position.

The U-shaped pipe quantity arranging in above-mentioned cylindrical shell and the quantity of the compressor in heat pump/multi-joint unit equate.

The bottom of above-mentioned U-shaped pipe is provided with strap, with against shock, ftractures.

Above-mentioned cylinder body bottom is welded with bolted firm banking.

Above-mentioned cylindrical shell side arranges the form that is used for observing internal flow motion state.

The utility model adopts inner symmetrical U-bend design, prevent inner splash, contribute to the oil of separator bottom to distribute to uniformly every compressor, while having eliminated components of system as directed load operation, endotracheal cold-producing medium flow velocity is too small and cause system oil return ability to decline, while being applicable to Multi-compressor parallel operation, gas and oil is balanced, has greatly improved the property safe and reliable to operation of heat pump/multi-joint unit.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is schematic top plan view of the present utility model.

1 gas outlet, 2 air inlet pipe, 3 baffle plates, 4 second spill ports, 5 forms, 6 first spill ports, 7 straps, 8 firm bankings, 9 bolts, 10U shape pipe, 11 cylindrical shells, 12 top covers in figure.

The specific embodiment

As shown in the figure: a kind of gas and oil balance-type gas-liquid separation device, comprise cylindrical shell 11, cylindrical shell 11 is interior arranges some U-shaped pipes 10, the bottom sides of U-shaped pipe 10 arranges the first spill port 6, the tip position of U-shaped pipe 10 arranges the second spill port 4, the top cover 12 of cylindrical shell 11 arranges baffle plate 3, in case the liquid that splashes producing when operation enters in U-shaped pipe 10, an air inlet pipe 2 of top cover 12 centre position welding, U-shaped pipe 10 quantity of cylindrical shell 11 interior settings and the quantity of the compressor in heat pump/multi-joint unit equate, the bottom of U-shaped pipe 10 is provided with strap 8, with against shock, ftractures.The firm banking 8 that cylindrical shell 11 bottom weldings have bolt 9 to connect, cylindrical shell 11 sides arrange the form 5 that is used for observing internal flow motion state.U-shaped pipe 10 works alone according to the conditions of demand of every compressor, that is: adaptivity oil balancing technique refrigeration system.The unit of the Multi-compressor parallel of this many U-shapeds of employing pipe design, can the running efficiency of keeping system and the normal oil level of crankcase, and the oil return that can not only solve compressor, can also make the oil return of each compressor have equal opportunities; Not only play good oil return and all oil effects, and make to move simultaneously in each compressor under more approaching pressure of inspiration(Pi), move.While having eliminated components of system as directed load operation, tracheae inner refrigerant flow velocity reduces and causes the decline of system oil return ability.

In the situation that having a plurality of outdoor Unit Combination, during system operation, if there is each unit module off-premises station, tell oil mass and recirculating oil quantity when unbalanced, the lubricating oil of the outdoor unit that oil return is too much accumulates in gas-liquid separator, break spill port oil return and compressor and tell oily balance, cause the pasta in separator ceaselessly to raise.When pasta exceeds second spill port 4, spill port 4 starts participation work, and the oil mass that makes separator return to compressor increases greatly, and too much oil returns to the compressor with balance pipe; The pasta of compressor bottom oil sump also can raise gradually, covers the bottom mouth of pipe of oily balance port.Now, under the differential pressure action of pressure at expulsion, unnecessary lubricating oil can be discharged in exhaust by oil balance tube, enters subsequently systemic circulation, returns in the separator of each off-premises station by the reallocation in systemic circulation.In separator by spill port 6 at the inferior compressor of on average getting back to.Repeat in the cyclic process of above-mentioned equal oil, oil return not stopping, lubricating oil convergence poised state again gradually in each outdoor unit, thus reach the autobalance of lubricating oil between each off-premises station.

By practical proof, the separator of self adaptation oil balancing technique has fundamentally solved oil return and the equal oily problem of module machine combined system well.
