Spin-on Oil Filter Dry Leakage Tester

In the Filter Paper & Filter Testers section, the Spin-on Oil Filter Dry Leakage Tester is mainly used to detect the dry leakage performance of the spin-on oil filter. This section is an important part of the filter quality control, which is used to ensure that there will be no abnormal oil leakage during the manufacturing and use of the filter, so as to maintain the normal operation of the engine and extend its service life.

Specifications

Feature

◆ Rigid clamping system : 3 years warranty program is employed

◆ Patented clamping system : No need to change collets according to tap hole size (M18 ~ M26).

◆ Reliable test mechanism. : No solenoid operated valves that will distort pressure difference and cause wrong test result are used in the way to pressure differential sensor.

◆ Testing both filters with gasket and filters without gasket are available in one machine with 20 minutes changeover time

◆ Both clamping by collet and push down type are available by simple test method selection switch. Machine push down top of filter or seaming cycle when clamping by collet is not available due to special structure of filters.

◆ 3 steps alarm system for individual test station failure checking. 1st Failure alarm (1st lamp ON) -> 2nd Consecutive Failure alarm (2nd lamp ON) -> 3rd Consecutive Failure alarm -> the test station stop working with alarming sound and lamp while other stations still on work

Safety

◆ Automatic stop by 1) Motor overload 2) Filter loading fail 3) Filter unloading fail 4) Filter unload guide fail 5) Low air supply 6) Wrong positioning of filter

Introduction

• The equipment will be capable of dry leak testing Spin-On type filters with diameter 65 – 105mm height 65 – 180mm fully automatically without any operators in attendance.
• The equipment will be capable of receiving a Spin On filter from a continuous flow slat conveyor with the open end down, placing the filter into the test machine, conducting a leak test to the specification and ejecting the filter assembly from the machine onto an output slat conveyor without any damage or scuffing to the product.
• Any filter assemblies that fail the leak test will be ejected from the machine onto a separate holding station for inspection and re-testing. The equipment will include systems which minimise the set up time required to change from one job to another.
• The equipment shall run fully automatically without any direct labour once set up. Leak testing example : The machine is capable of pressurising the filter assembly to 600 kPa with air, maintain this pressure for 10 seconds whilst checking the filter leakage rate. The maximum allowable leakage is 0.5cc within the 10 second period at 600 kPa air pressure.
• We use very sophisticated Low Range Differential Pressure Transducer made by USA manufacturer which is very famous in manufacturing pressure sensors and ISO 9001 registered and QS-9000 compliant company, Reliable pneumatic regulators (CKD, Japan) and Controllers ( Yokogawa, japan) are employed.
