gear trembling and noise and expulsion

(1) The intake air

①speed reducer types pump body with both sides of the cover for lineal adjoin with the hard seal adjoin surface flatness not cope with demands, the pump at exercise, easygoing to inspire air; likewise, the end cap with pressing pump likewise for lineal touch between the lid and the air is likewise easy sank in; if the gland for plastic productions, owed to harm or distortion owed to temperature alters, just likewise cause Mifengbuyan into the air. Except this defect: while the flatness of fewer than the demanded pump or pump cover demands, "eight"-formed route backward and forward with emery grinding plate, surface grinder grinding it flatness of not much 5μm, and the demand to ascertain that the plane of the vertical hole demand; for the pump covering and the gland at the leakage, different adhesives canful be surfaced with epoxy resin for sealing off.

② Universal skeleton oil seal on the pump shaft is sealed off. If the cards the tight lip spring falling off, or anti-oil packet, or lip stress aging, will make the oil seals the backend frequently in damaging pressing state and inspired air, could commonly be substituted with brand-new oil seal to be called.cycloidal speed reducer

③ tank oil isn't adequate, or the suction nozzle isn't plugged in to the oil beneath the pump intake air will, to add on the oil inner the tank to the oil marks; oil return pipe mouth open, occasionally owed to the instantaneous damaging force inward the system leading the air counter irrigation to infix the system, return pipe mouth ought likewise be put in to the oil beneath.

④ pump mounting place from the oil surface is excessively high up, particularly while the pump speed is brought down, as they can't ascertain the essential level of vacuum inward the pump suction chamber Suction deficient intake air. You ought adapt the proportional height of the pump and the oil, to cause it match the designated demands.

⑤ suction filter the dirt clogged or excessively low capability, oil absorption opposition enhanced inspired air; additional, into the oil port big caliber air mayhap brought in. Washable oil filter, or choose a bigger capability, and the importation and exportation of diam oil filter. So, not entirely to forbid the inhalant of air, but as well to forbid the generation of noise.

(2) mechanistic causes

① Connectedness of the pump and coupling owed to unregularities demands and brings forth quivering and noise. Ought be demanded for adaptation of couplings.

② dirt into oil pump gears and additional constituents wear strain noise. Ought substitute oil, raising filters, take apart the pump cleanup; severely assumed gear to be amended or substituted.

③ Discredited or gravely assumed parts of the pump will bring about quivering and noise: specified as tooth fault or pitch fault, bad contact of two gear tooth surface harshness of tolerance, convention line length, the backlash is likewise low, two gear the contact region isn't indexing circuit location. In this event, substitute the gear or the speed reducer types on the enquiry. Concurrently, the needle roller bearing cage breaking, the length of the shaft journal and needle wear, could pass to the bearing revolution bad and yield mechanistic noise, and the require to overtake the gear pump, substitute the needle roller bearings
