CVS 50-1-DMV, Инструкция по эксплуатации

Страница: 2 / 12

Installation and Operation
- Upon removing the pump from carton,
inspect for possible damaged or missing
components from transit from CVS
Controls. Contact a CVS controls
representative should there be any
concerns.
- Blow out and remove potential debris
from supply line before hooking up
supply air/gas to inlet. Supply pressure
should be regulated with a maximum
setting of 50 psi.
- Connect suction line to pump head.
- A line check should be installed in the
discharge line close to the point of
injection. (note the direction of the flow
arrow) CVS Controls offers the
CVS-B-0283 line check in stainless steel,
for all plunger sizes which will
withstand a working pressure of 6000
psi.
- Connect the discharge line to the ¼”
FNPT in both the line check and the Top
Bushing (CVS-A-0152) of the head
assembly. Ensure the line is clear of all
debris.
- Partially open Bleeder Valve
(CVS-A-0123)
- Connect the gas supply line, considering
the pressure required of the pump. If
the gas exceeds 50 psi, the supply
should be equipped with a regulator to
reduce the pressure to 50 psi.
Lubrication
A stick lubricator (CVS-A-3179) is inserted into
the grease assembly (CVS-A-0558) upon
manufacturing. CVS controls has available and
recommends CVS-A-3179 for most fluids. No
lubrication stick is required if the pump is
equipped with Teflon packing and chrome
plated plunger.
Operation
1. Remove the body cover (CVS-B-0004)
and cover gasket (CVS-B-0036)
2. Open the main air/gas supply valve and
slowly open the exhaust valve
(CVS-A-2489). The pump should
automatically start. Ensure the suction
line is primed with fluid, and then test
the pump head by opening the Bleeder
Valve (CVS-A-0123). The fluid escaping
from the bleeder valve may contain
bubbles. As soon as the bubbles
subside, close the bleeder valve for
normal operation.
3. Adjust for desired volume by
considering pump speed using the flow
control. Consider the position of Brass
Adjusting Pin (CVS-A-0035)to adjust
stroke.
