Background technique
Membrane compressor is a kind of positive displacement compressor of special construction, there is compression ratio large, good airproof performance, pressurized gas is not by the feature that lubricant oil and other solid impurity pollute, usually, diaphragm type compressor is primarily of driving mechanism, crankcase components, cylinder part, lubricating oil system, the compositions such as air pipe parts, wherein air pipe parts are made up of air inlet pipeline and gas exhaust piping etc., under normal conditions, compressor inleting pipe Lu Weiyi stop valve, front end connects low-pressure gas source, rear end is directly connected with compresser cylinder suction port by one section of straight-through pipeline, the deficiency that this structure exists is, if unclean by pressurized gas, wherein be mixed with in solid particle or gas source pipe and have welding slag, rusty stain and dirt easily enter compressor air cavity, and the air cavity of diaphragm type compressor is made up of cylinder cap and diaphragm, the dirt that diaphragm is easy to by entering is broken, cause the chain shutdown of compressor alarm failure, user cannot be used.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of diaphragm type compressor with inlet air filter system, in diaphragm type compressor air inlet pipeline, increase inlet air filter system, and diaphragm is effectively protected.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The utility model is a kind of diaphragm type compressor with inlet air filter system, comprise air inlet stop valve, the suction port of air inlet stop valve is connected with source of the gas, diaphragm type compressor also comprises duplex strainer, first tee union, second tee union, differential pressure transmitter and compressor control system, air inlet stop valve connects duplex strainer, duplex strainer comprises entrance point tee ball valve, outlet end tee ball valve, first cartridge filter and the second cartridge filter, the relief opening of air inlet stop valve is connected with the entrance point tee ball valve of duplex strainer, the outlet end tee ball valve of duplex strainer is connected with compresser cylinder import, the height of differential pressure transmitter, low pressure port is connected entering of duplex strainer respectively by the first tee union with the second tee union, outlet port, detect entering of duplex strainer, the pressure difference in outlet port, along with the progressively obstruction of filter screen in the first cartridge filter or the second cartridge filter, its corresponding pressure reduction can progressively increase, afterwards the pressure signal detected is converted to standard 4-20mA electrical signal and sends compressor control system to.
Further improvement of the utility model is: the filter screen of duplex strainer is detachable.
Further improvement of the utility model is: differential pressure transmitter is explosion-proof type, and band digital display function.
During normal boot-strap work, open inlet shutoff valve, ensure that duplex strainer imports and exports tee ball valve opening is same orientation simultaneously, and low pressure gas now by one of them cylindrical shell of duplex strainer, after filtering out solid particulate matter wherein, enters compressor air cavity.Differential pressure transmitter detects duplex strainer inlet and outlet pressure by tee union simultaneously, show its pressure difference, and be transferred to compressor control system after pressure signal conversion, when the signal value that compressor control system receives is the alarming value originally arranged, warning reminding user filter screen blocks, and need change filter screen.User need not shut down; as long as the inlet/outlet tee ball valve opening of duplex strainer is switched to another location; low pressure gas, now by another cylindrical shell of duplex strainer, is reported to the police and is eliminated, and maintenance person is according to one end filter screen changing operational instruction and replaceable obstruction cylindrical shell.
The beneficial effects of the utility model are: in diaphragm type compressor air inlet pipeline, increase inlet air filter system; prevent solid particle from entering in air cavity and break diaphragm; effectively protect diaphragm; improve its working life; simultaneously; have and automatically detect blocking function, prompting user changes the filter screen that duplex strainer wherein blocks when not stopping diaphragm type compressor operating, substantially increase the Economy of user.
