Definitions
- the present invention relates to a screw compressor according to the preamble of patent claim 1.
- check valves are usually arranged on the suction side of the compressor to prevent it when switching off the compressor drive by the pressure difference before and after the compressor to a
- check valves also serve to ensure that the pressures of the system before and after the compressor do not compensate when the compressor is stopped.
- Such systems typically have filters on the suction side of the compressors to prevent dirt from entering and damaging the compressor.
- Compressor housing integrated check valves common, which are opened by the gas flow and closed by a compression spring.
- DE 10 2006 016 317 AI shows an exemplary construction which is actuated by a compression spring. In such
- CONFIRMATION COPY Compressors are also customary in the compressor housing integrated suction gas filter.
- the check valves commonly used in small compressors, which are actuated by a compression spring, are not advantageous because of their large flow losses.
- the streamlined, operated by compressed gas check valves, which are common in systems with larger compressors, are expensive.
- the separately arranged components require a plurality of housings, which are connected by connecting elements, which leads to high expenditure on machining and assembly. Pipelines are required to direct gas from the pressure side of the compressor to the check valve, the
- Check valve has low flow losses. This construction is to be designed as inexpensively as possible and should have the least possible number of pipelines and fittings in order to minimize the risk of gas leaks. The installation of a suction gas filter should also be possible.
- the object underlying the invention is achieved by a screw compressor with the features of claim 1.
- the non-return valve located in the compressor housing together with the suction gas filter for its control supplied with compressed gas, wherein the compressed gas passes through drilled or cast in the compressor housing channels to the check valve.
- a likewise arranged on the compressor solenoid valve is present, which serves for switching on and off the compressed gas supply.
- Suction gas filter coaxially arranged around the check valve so that the valve disc of the check valve moves within the Sauggasfilters.
- Design is a cover of the compressor housing at the same time cover of the
- This integrated solution is less expensive than using separate components in the system. By eliminating external lines assembly costs are saved and the risk of gas leakage through broken pipes or leaking pipe fittings is avoided.
- the check valve controlled by compressed gas has lower flow losses than the check valves commonly used in small and medium screw compressors and actuated by a compression spring.
- Fig.2 the check valve of Fig. 1 in the open state (screw compressor in Business);
- Fig. 3 the check valve of Fig. 1 in the closed state (screw compressor stopped);
- Figure 4 is a sectional view of the first embodiment of a screw compressor, showing a system of bores and solenoid valves through which gas, which is under final pressure, is passed from a gas space behind the screw rotor a channel for a rod of the check valve in the lid;
- Figure 5 is a sectional view of a section of a second embodiment of a screw compressor according to the invention, showing a system of holes and a shut-off valve, whereby a bypass between the gas space in front of and behind the closed check valve can be made.
- a position reporting system which may optionally be present to report the switching position of the check valve.
- a compressor housing 1 of a screw compressor a screw compressor
- Suction gas filter 2 is arranged, which has the shape of a cylinder open on both sides.
- the compressor housing 1 is closed by a cover 3, so that a change, or the cleaning of the suction gas filter 2 is easily possible.
- the lid 3 is sealed by a first seal 4, for example, an O-ring to the housing 1.
- a first seal 4 for example, an O-ring to the housing 1.
- At both ends of the suction gas filter 2 is fitted in the housing 1, so that the gas entering the compressor is forced through a screen fabric 5, which
- Suction gas filter 2 has, and not to flow laterally past this.
- Valve rod 8 is arranged.
- the valve rod 8 is guided by a linear ball bearing 9, so that the valve disc 6 and valve rod 8 are jointly axially displaceable.
- Linear ball bearing 9 is arranged in a first channel 13 in the lid 3. The linear linear
- Lid 3 limited in the other direction of movement moves the valve plate 6 against a valve seat 10 which is arranged in a bore in the compressor housing 1, which is also arranged coaxially with the valve disk 6 and the suction gas filter 2.
- the valve seat 10 is sealed by a second seal 11, for example an O-ring, against the compressor housing 1 ⁇ .
- Screw rotor 14 of the compressor is formed.
- the check valve 7 In a screw compressor at standstill, the check valve 7 as shown in Fig 3, closed. This prevents a pressure equalization of the different pressures of the working medium takes place before and after the screw compressor.
- pressurized gas In order to close the check valve 7, pressurized gas has to be disposed downstream of the screw rotor 14 from a third gas space 15 which is located downstream (with regard to a gas flow in the compressor during a normal operation of the compressor)
- a plurality of channels and a solenoid valve 17 are arranged in the compressor housing 1 and in the lid 3 .
- a second channel 16 extends to the solenoid valve 17, which is arranged directly on the compressor housing 1.
- the solenoid valve 17 opens so that the check valve 7 closes.
- the solenoid valve 17 is open, the compressed gas from the gas chamber 15 via the channels 16, 22, 23 and 24 passes through the compressor housing 1 in the lid 3 and there in the first channel 13.
- the valve rod 8 In the first channel 13 is the valve rod 8.
- the compressed gas pushes the valve rod 8 with the valve plate 6 to the Valve seat 10.
- the valve is closed. This pressure equalization between the gas (compressed gas or by the screw rotor 14 compressed gas) in the suction line 18 and the gas in the third gas space 15 is prevented.
- the screw rotor 14 generated in the first and second gas chamber 12 and 19 between valve seat 10 and screw rotor 14 has a lower ⁇ pressure which is lower than the pressure in the suction line 18 so that the check valve 7 opens and in Fig.2 shown position occupies.
- a system of bores and a shut-off valve as shown in Fig.5 is provided in a second possible embodiment of the system according to the invention. As a result, a bypass between the second gas chamber 12 and the suction line 18, which are separated by the valve disk 6, which rests against the valve seat 11, are produced.
- a sixth channel 20 in the compressor housing 1 is connected by two channels (seventh channel 21 and eighth channel 29) to the second gas chamber 12 and the suction line 18.
- a check valve 25 At the junction of sixth channel 20 and seventh channel 21 is a check valve 25 in
- Compressor housing 1 is arranged so that when closing the shut-off valve 25, the connection of the sixth channel 20 to seventh channel 21 is disconnected or closed. During maintenance, the shut-off valve 25 can be opened, so that the connection of the sixth channel 20 to seventh channel 21 is opened, and thus the pressure between the gas space 19 second gas space 12 and the suction line 18 can compensate.
- a position reporting system 30 is mounted on the cover 3 of the check valve 7, by means of which an adjustment path of the valve rod 8 can be detected.
- the detection can in individual embodiments, for example, on mechanical, electrical or electro-magnetic, and on magnetic basis.
