    While Ariel compressors share many similarities, each model has aspects that are unique to the particular type. If you as an operator are familiar with Ariel compressors, it is still impor- tant to review this manual to determine the differences. If you are new to Ariel compressors it is critical that you become very familiar with this manual prior to operating the compressor.

    (see Figure 1-5: on page 1-6). When compressor location or operating conditions change, the lubrication rates should be changed according to the Ariel Lube Specifications shown in Table 4-1 on page 4-8. When two or more force-feed lubricator pumps are manifolded into one distribution block, the following procedure is recommended to adjust pump rates: Start with each pump adjusted to full open.

  • Page 104: Piston Rod Packing Ring Material

    AINTENANCE Piston Rod Packing Ring Material In the past, bronze was the standard material for Ariel packing rings. Bronze, however, is unsatisfactory for sour gas service, (hydrogen sulfide in the gas). PEEK, cast iron and Teflon provide outstanding service with sour gas, and since they perform equally well with sweet gas, they are now the standard materials.

    Packager’s instructions regarding where to set the VVCP. Also reference the VVCP data sheet in the Ariel Technical Manual Parts Book. The VVCP piston ring is designed not to be gas tight, to allow a nearly balanced gas pres- sure for ease of VVCP adjustment with the cylinder pressurized.
  • Page 110 : JGW, JGR 5 - M ODELS ECTION AINTENANCE the VVCP can be adjusted when the cylinder is pressurized, but difficult to turn when the cyl- inder is vented. This problem is corrected by disassembling the VVCP and cleaning. To adjust the volume, loosen the stem locking handle, so that stem is free to turn. Turn the stem by use of the hand wheel on the outboard end of the shaft.

These troubles are most often traced to liquid, dirt, improper adjustment or to operating personnel being unfamiliar with Ariel compressors. Difficulties of this type can usually be corrected by cleaning, proper adjustment, elimination of an adverse condition, replacement of a relatively minor part or proper training of the operating personnel.
