RYB internal gear cycloidal gear pump stuck fault diagnosis and processing methods
   RYB internal gear cycloidal gear pump is the diesel engine fuel supply system, "heart." RYB internal gearing cycloid pump precision coupling lag, will lead to unstable engine speed, serious engine flameout can cause accidents and speed.
   1, RYB internal gear cycloid gear stuck reason
   For the old RYB internal gear cycloidal gear pump, the reason for its stagnation mostly diesel is not clean, there is mechanical impurities between the plunger and the plunger sleeve, Po Taibang or plunger and plunger sleeve surface is pulled, or the top of the plunger Corner was bump caused by bump.
For the new RYB internal gear cycloidal gear, the reason for the stuck are the following:
   (1) At present, some manufacturers and maintenance units do not pay attention to the selection of high quality diesel during commissioning, which leads to the actual colloidal content in the diesel used for debugging is larger and the acidity is higher. After this debugging, in the RYB meshing cycloidal gear pump precision coupling with the surface adhesion of a layer of residual oil film. If the RYB internal gear cycloidal gear pump is stored too long, this layer of oil will gradually generate organic sediment and gel, installed will have a sluggish phenomenon.
   (2) RYB internal meshing cycloid gear pump storage is not good, lax packaging, moisture-proof rust-proof material missing or damaged, the tubing joint dust cap damage or loss, will also have a phenomenon of stagnation.
   2, the card lag processing
   For used RYB internal geared pumps, locate the stuck plunger coupling and remove it and clean it with clean diesel. If the plunger coupling is pulled by mechanical impurities, can be cleaned with a clean oil. If the top of the plunger is bump generated glitches (the naked eye is difficult to observe), when the plunger is retracted into the plunger sleeve will send astringent hair card, at this time must not repeatedly rotate or twitch the plunger to prevent burrs scratch the plunger set. The correct approach is: pull the top corners of the plunger pulled into the hole with the plunger sleeve flush with the center, slowly turning the plunger, there will be a sense of block. When the switch to a certain location block sense disappears, it means that the top corner of the plunger bump just in the plunger sleeve into the hole. Marked at the location, the top edge of the plunger pushed out of the plunger sleeve, with fine sand grinding the bump area. Grinding, fine sand plane and the plunger axis was 45 ?, gently push and pull a few times to eliminate edges and corners can be burr. But not too much grinding, so as not to affect the cylinder starting angle of consistency and fuel supply uniformity.
   For jammed new RYB internal gear cycloidal pump, the following methods can be used to deal with:
   (1) The appropriate amount of gasoline or diesel oil is injected into the RYB internal gear pump and the governor, and the camshaft is rotated repeatedly to move freely the RYB internal gear, the gear lifter and the flywheel, etc. Rusty card issue, resulting in diesel speed.
   (2) For the upper and lower body can break down the RYB internal gear cycloidal gear pump, the pump body can be placed flat, open the side cover, remove the pump head fastening nut, remove the pump head, clamp the plunger Root, slowly remove the fault cylinder plunger and spring (not to injure the plunger), with clean gasoline or diesel repeatedly cleaned, washed and loaded (note the plunger arm must be placed in the regulating fork), and alternating Tighten the pump head nut, turn the camshaft, pull the pump control handle review.
   (3) For the integral RYB internal gear cycloidal gear pump, you can open the side cover, turn the camshaft, with a screwdriver inserted into the quill plug spring holder gently pry, forcing the plunger down after reset, exposed to the column Inject the clean petrol or diesel fuel at the base of the plunger outside the plug sleeve and turn the camshaft. When the plunger reciprocates freely, the front and the back of the two racks move sensitively, and then the net cleaning oil is thrown in, and a proper amount of clean lubricating oil is injected into the governor housing.Metal Fence Roll Forming Machine, Fence is mainly used for highway, highway, highway bridge on both sides of the shield used as fence netting, can also be used in airports, ports, docks safety protection, municipal construction of parks, lawns, zoo isolation and protection, roads, residential area, hotel, hotels, supermarkets, entertainment protective and decorative products, etc. Welcome to provide your own profile Or send samples to us, We have the most professional designers Free to serve you, Looking forward to cooperating with you.
