Caminix Valve test bench was established in 2009 ,during
these years Caminix valve testing equipment has been
developed into the international market as the superior leader
in China domestic market, regarding both the market share
and the advanced technology. Our valve
testing equipment have being sold to over 20 countries
and won a high reputation with good quality and strong after sale
services.All of our products are designed , developed, manufactured
and tested by ourselves. The product development is influenced by
the experience that many of our customers have made during their
various assignments and also the strong engineer team supporting.We
have various types of Valve test bench/ valve grinding
machine for different valves with different
specification, Please check our products details and welcome
to give us some suggestions.Our highest priorities are to
secure the production , products quality and after sale
services.Data sheet of CMX-L300 Vertical Valve test
bench forTesting gate valve, globe valve,check valve, ball
valve etc up to DN300Machine OverviewCMX-L valve hydraulic test
bench is based on our company's many years of production valve
testing equipment technology, and is managed and produced in strict
accordance with the ISO9001 quality management system. The products
meet relevant standards such as GB/T-13927-92 "General Valve
Pressure Test", ZBJ16006-90 "Valve Test and Inspection" and AP1598
American Standard. The test bench integrates hydraulics,
machinery, electrical appliances and medium storage and
circulation. It has the advantages of reasonable structure, perfect
function, stable performance and high degree of automation. It is
widely used in high and medium straight flange valves with a
nominal diameter of DN15-300mm. It is the most ideal valve testing
and testing equipment for industrial units such as valve
manufacturing, petroleum and petrochemical, natural gas, water
supply and drainage engineering, power plants, and valve
maintenance stations.2. Structure and working principle of
CMX-L300:1. CMX-L valve hydraulic test bench consists of hydraulic
system, electrical control system, high and low pressure water pump
pressure supply device system, oil pressure, water pressure
instrument system, control valve system, clamping table system, top
pressure cylinder system and hydraulic pressure The composition of
the medium storage circulating water tank, the test process and
results, meet the relevant regulations and requirements.2. The
downward workbench of the test bench adopts the valve flange end
face seal, and the claw is used to directly clamp the back of the
valve flange for compression. The clamping mechanism is directly
driven by the clamping cylinder of the clamping jaw to work, and
the radial movement is composed of an oil cylinder and a lever. ,
Realize the radial synchronous movement of each gripper, no
external force on the test valve, the top pressure cylinder on the
test bench can move up and down horizontally, not limited by the
length of the test valve structure, the top pressure cylinder
horizontal frame has the function of hand push to rotate 90
degrees, which is convenient for the valve loading and unloading.3.
The hydraulic pressure supply water pump is powered by air pressure
(0-0.7Mpa), and the direction is automatically reversed through the
reversing valve, so that the high-pressure water cylinder (pump)
automatically reciprocates to work, and the water suction check
valve and the water outlet check valve are interchanged
Continuously supply pressure to the tested valve to meet the
pressure requirement of the tested valve.4. It is suitable for
straight-through type: flange, welding, thread and socket valve
sealing and strength performance test.5. Working process: adjust
the cylinder pressing pressure according to the nominal diameter
and pressure of the valve (refer to the pressure comparison table)
- press the workpiece - turn on the low water pump for quick water
injection - turn on the high pressure water pump (the pressure can
be set) - keep the Pressure timer - manual pressure relief,
reset.6. Set the self-locking function of the compression cylinder:
when there is pressure in the test valve cavity, the compression
cylinder cannot be released. Protects against misoperation.7.
Timer: Set the pressure holding time - when the pressure reaches
the set pressure, press the button to start timing - when the
pressure holding time is reached - the alarm light buzzes and the
red light flashes.8. Air cooler: reduce the oil temperature and
prolong the trial life of the equipment. TEST SIZEPNTESTING
