Gear oil pump wear repair

1, diesel gear oil pump drive shaft and bushing repair after wear due to the weight of the gear pump gear and the passive gear meshing generated when the radial thrust, easy to shaft and bush bore eccentric wear and tear, increased clearance. Therefore, oil leaks due to increased clearance at work, reducing the amount of oil supply. Drive shaft and bushing wear, you can repair journals or repair bushing method to restore coordination gap. In the minor wear of the journal, simply press the old sleeve put on the new sleeve, and the shaft can not be repaired, so with the gap can be restored to the allowable range. In the shaft and bushing wear are very serious, with a large increase in the gap, not only to replace the bushing, and the shaft also applies chrome or vibration welding to increase the diameter, and then grinding to the standard size to restore the journal and Bushing requirements. 2, the pump housing cavity and gear wear after repair Pump housing cavity and gear wear, a significant impact on the pump oil. When the shaft and the bush or shaft hole wear serious, work in the tooth top and the pump chamber cavity surface will have an undivided contact. And because the pressure of the oil chamber is higher than that of the oil chamber, under the action of pressure difference, there is more contact between the tooth top and the oil inlet chamber of the pump housing. As a result, the cavity of the pump housing is more worn there, Top clearance increases. As a result, the pressure difference between the oil pump inlet and outlet oil chambers is reduced, and the effect of scraping oil and pressure oil on the gear teeth is reduced, resulting in a decrease of the oil supply pressure and a decrease of pump oil. The pump chamber cavity wear generally adopt lumen inlay method to be repaired. Secondly, due to the gear tooth wear in the direction of tooth thickness, so that the main and driven gear meshing gap increases. Its wear characteristics are unilateral heavier wear, so the gear can be turned 180 degrees use. 3, the gear end face and pump cover wear repair gear end face and the pump cover the plane between the left a certain gap, said the end gap. Work wear and tear on the contact surface between the gear end face and the pump cover plane will increase the gap of this face, when the limit is exceeded, the pump oil will have a significant impact. When the gear end wear, the end surface can be polished, and then grind oil pump housing decomposition surface to ensure that the pump end clearance in the required range.

Liquid Reservoir

4 Channel Reagent Reservoirs,8 Channel Reagent Reservoirs,12 Channel Reagent Reservoirs,96 Well Reservoir,384 Well Reservoir, from Yongyue Medical, is made of strong clear polypropylene (PP). Low profile designation which is suitable for small volume robotic tips used in high flux instruments. In the automatic pipetting process, the reservoir can perfectly overcome the surface tension of the liquid and minimize residual liquid

Our Reservoir Plates are perfect for storing volumes of samples to be pipetted into other microplates for further applications.
These plates are manufactured in cleanroom facilities which are certified free of RNase, DNase, human genomic DNA and endotoxins. We use only the highest medical grade virgin polypropylene with high resistance against chemicals such as DMSO, phenol, and chloroform. Pyramid channel bases are best for small volume recovery. The standard SBS footprint ensures its compatibility with automation.
Our sturdy and reusable reagent reservoirs can stand-up to autoclaving, exposure to temperature extremes, and chemicals. Made from polypropylene these reservoirs offer a stable base that makes them suitable for manual procedures as-well-as automation.
These fully automation compatible reservoirs feature an SBS footprint and can be used in plate handlers or stackers. To minimize space on platforms (when a stacker is not in use) or under hoods, these reservoirs can be filled and stacked.

High Quality PP, Stable with Lab Common Reagents, including DMSO, etc
Conical Bottom Design To Save Expensive Reagents
DNase/RNase & Pyrogen Free
Stable at -80℃
Conformed to ANSI/SBS Standards
