In order to extend the life of the plunger metering pump, it is necessary to do routine maintenance work, then in daily life, how to maintain the plunger metering pump? The following is about the plunger metering pump Routine maintenance introduction. Plunger metering pump routine maintenance 1, should always check the designated tank within the rotation box, not too much or too little, the lubricant should be clean and free of impurities, and pay attention to timely oil change, oil change deadlines. 2, the leakage of packing seal at no more than 8-15 drops per minute, if the leakage exceeds, the packing should be properly tightened cap; but not to fill the temperature rise too high, so that the axle or burn out Plunger seal packing. Pump temperature in the main part of the provisions of the operation are as follows: Motor temperature ≤ 80 ℃; Rotating the oil temperature within the tank ≤ 65 ℃; Packing cavity temperature ≤ 110 ℃. 3, pump operation 2000-3000 hours later, should be opened to check the internal parts, connecting rod bushings and other wear parts into and repair or replacement. 4. If the pump is deactivated for a long time, the medium in the pump cylinder should be drained cleanly. For example, if the corrosive liquid is corrosive, run it for 5 minutes with clean water before shutting down and wash the remaining liquid in the cylinder to prevent decay after stopping.

HDT Vicat softening temperature Tester
The HDT Vicat Softening Point Apparatus is a testing instrument used to determine the softening point of a material. It is commonly used in the plastics industry to evaluate the heat resistance and thermal stability of polymers.
The apparatus consists of a heating bath, a test specimen holder, and a needle or a flat-ended plunger. The test specimen is placed in the holder and immersed in the heated bath. The temperature is gradually increased at a specified rate, and the needle or plunger is applied to the specimen at regular intervals.
The softening point is determined by observing the point at which the needle or plunger penetrates a specified distance into the specimen. This indicates the temperature at which the material starts to soften and lose its dimensional stability.
The HDT Vicat softening point apparatus is designed to meet international standards, such as ISO 306 and ASTM D1525. It provides accurate and reliable results, allowing manufacturers to assess the suitability of materials for various applications and ensure product quality.
