Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0012] Such as figure 1 with figure 2 The shown vinyl chloride gas compressor includes a compressor host 6 provided with an intake buffer tank, and this embodiment is a WW type vinyl chloride gas compressor, which has two primary cylinders and a secondary cylinder , the intake ports of the two first-stage cylinders are respectively connected with an intake buffer tank 1 and an intake buffer tank 4; the crankshaft of the compressor host 6 is connected with three piston rods, which are respectively used to drive the piston in the three The reciprocating piston rods in each cylinder are equipped with a packing device outside each piston rod. The three packing devices are respectively the packing device 2 of the first-stage cylinder, the packing device 3 of the first-stage cylinder, and the packing device of the second-stage cylinder. 5. These packing devices all inclu...

Abstract

The invention discloses a chloroethylene gas compressor, and relates to the technical field of compressor manufacturing. The chloroethylene gas compressor comprises a compressor main machine with a gas inlet buffer tank, and a bent axle of the compressor main machine is connected with a plurality of piston rods. A packing device is arranged outside each piston rod, and each packing device comprises a shell which is arranged on the corresponding piston rod in a sleeving mode and is provided with a gland. Each gland is provided with a gas channel, a sealing unit and a gas recovery unit are arranged in a cavity of each shell, and each gas recovery unit is provided with a gas channel communicated with the corresponding gland gas channel. The gas channels of the glands are connected with a pipe joint which is connected with the gas inlet buffer tank. Compared with the prior art, the problem that leakage can be likely to happen to an existing chloroethylene gas compressor can be solved.

Description

technical field [0001] The invention relates to the technical field of compressor manufacturing, in particular to a gas compressor for vinyl chloride gas. Background technique [0002] Vinyl chloride compressors are used in the vinyl chloride chemical industry. Vinyl chloride gas is a flammable, explosive, colorless gas with low toxicity and slightly aromatic odor; therefore, the vinyl chloride compressor should be installed separately in an independent In the compressor workstation, there should be good ventilation conditions; at the same time, the leakage of vinyl chloride gas should be prevented when the vinyl chloride compressor is in operation, and the most likely place to cause the leakage of vinyl chloride gas is the joint between the piston rod and the packing assembly; At present, the packing components of vinyl chloride compressors produced on the market are all composed of multiple sealing rings set outside the piston rod; There is residual vinyl chloride gas in ...
