Product Description
Characteristics of the screw refrigeration compressor
Reciprocating positive displacement piston compressor, screw compressor is a rotary positive displacement compressor. Compared to piston compressors, screw type refrigeration compressor has the following advantages:
(a) Small size, light weight, simple structure, fewer parts, is only equivalent to a piston compressor 1 /3 to 1 /2;
(b) High speed, stand-alone cooling capacity;
(c) Less wearing parts, maintenance convenience;
(d) Smooth operation, low;
(e) Single-stage pressure ratio can be used at lower evaporating temperature;
(f) Low exhaust temperature, pressure ratio;
(g) Not sensitive to the wet stroke;
(h)Cooling capacity of between 10% to 100% stepless adjustment;
(I)Easy to operate, easy to achieve automatic control;
(j)Small size, easy to realize the unit of.
Screw compressors work to keep the working chamber is injected into lubricating oil, plays lubrication, cooling, sealing and muffler role, as well as lubricating the main bearings, thrust bearings, shaft seal lubricant to promote oil-free piston, balanced piston pressure of the oil, these oils last and high-pressure gas mixture discharge of the compressor. The oil must be separated, after cooling, filtration, pressurized circulating.
(1) inspiratory filter
Suction filter is mainly composed of shell and metal filter. The shell is installed on the aspirated thermometers, pressure gauges and fuel valves. The refueling valve is the the the site of refueling in the unit run-time.
(2) oil separator
Screw compressor oil separator with vertical and horizontal, and the main filler type. My company is currently widely used horizontal two oil, three sub - oil way, high efficiency oil separator, and up to 10PPm. Oil separator and is the compressor, the basis of the motor to make the unit compact.
(3) oil cooler
The oil separation from oil absorb the frictional heat and gas heat leaving temperature ( close to the exhaust gas temperature ). Lubricants normal use temperature is 30 to 60 deg. C, high oil temperature to reduce viscosity, make sealed weakened, increased leakage, reducing the efficiency of the
(4) crude oil filter
Work properly to protect the pump, lubricating oil into the pump crude oil filter to filter out impurities. The filter shell and metal filter housing has a fuel valve, the initial fuel through this valve. Fuel oil through the system vacuum, you can also pump fuel.
(5) pump
Pump compressor is to increase the oil pressure. Often used gear pump or the pump rotor. Before starting the first check the pump direction of rotation.
(6) oil filters
Oil filters by the shell and filter, after assembly in the pump, before the oil distributor, the fine particles in the filtered oil to protect the compressor rotor and shaft seal. To be able to filter out the fine metal debris in the filter contains a permanent magnet.
(7) hydraulic control valve
The role of the hydraulic control valve to adjust the injection pressure compressor. Entering the compressor oil pressure is too high will lead to the injector too large, both the compressor suction flow rate, increased compressor power consumption will also increase the possibility of seal leakage; Low oil pressure, make the fuel injection quantity is too small to weaken the role of the lubricant.
(8) check valve
Check valve, also known as a check valve or check valve. Screw compressor suction cases similar to the piston compressor, the exhaust valve can be automatically separated from the high pressure gas chamber, the compressor suddenly shut down and not had time to close the suction and discharge cut-off valve, the refrigerant gas from the high pressure side flows to the low pressure side of the compressor rotor in the reverse phenomenon of the role of air.
"HEN BUSCH GROUP" whose headquarters is located in Germany is the enterprise of manufacturing specialized air conditioned, cooling equipments, electronic control apparatus and also referring to realty as well as information industry. The amount of annual business selling is nearly 2 billions Euros. HEN. BUSCH air conditioner is one of the main productions in its business titled group brand.
