[Lubricants Network] gear lubricating oil pump in the process of using, there may be some failures, we must learn to deal with failure, in order to ensure the pump can be put into operation as soon as possible. Now to introduce the gear pump lubrication problems and solutions. Gear Lubricants Pump Gear Lubricants Pumps Common Problems and Solutions Symptoms Causes Remedies Not to drain or drain less 1. Inhalation height too high Exceeds rated value 2. Inhalation pipe air leaks 3. Incorrect direction of rotation 4. Suction pipe plug or valve Off 5. The liquid temperature is low and the viscosity increases 6. Serious damage to the gear and pump body 1. Raise the suction side or reduce the tube resistance 2. Check whether the joints leak or leakage and sealed with sealing material such as asbestos 3. Correct the direction as directed by the pump 4. Clear the blockage and open the valve 5. Preheat the fluid and reduce the discharge pressure if possible Decrease the oil discharge 6. Disassembly Check seal and other parts for replacement Oil leakage 1. Shaft The seal is not adjusted 2. Seal wear, clearance increased 3. Mechanical seal static ring and moving ring friction surface damage or burr scratches and other defects 4.
Spring relaxation 1. Readjustment 2. Production Tighten the nut, Or replace the seal 3. Replace the static and dynamic rings or regrind 4. Replace the spring noise or vibration 1. Suction mesh or filter plugging 2. Straw into the shallow oil pool 3. Pipe into the air 4. Exhaust pipe resistance is too large 5 Serious wear on gears, bearings or side plates 6. Inhalation of liquid Viscosity is too high 1. Clear the dirt on the filter 2. The suction pipe should be inserted into the oil tank about 0.5 meters 3. Check the connections to seal it 4. Inspect the pipes and valves and discharge the clogged objects or adjust Pipelines to reduce elbows, valves, etc. 5. Replacement of new gears, bearings or side panels 6.

Tapping Screw
Although there are many types of tapping screws, they all have the following similarities:
(1) are generally made of carbonized carbon steel (accounting for 99% of total production). It can also be made of stainless steel or non-ferrous metals.
(2) The product must be heat treated. Carbon steel tapping screws must be carbonized and stainless steel tapping screws must be solution hardened. In order to make tapping screws to meet the requirements of the standard of mechanical properties and performance.
(3) The product surface hardness is high, the core toughness is good. That is, "soft inside strong outside". This is a major feature of tapping Screw performance requirements. If the surface hardness is low, it can not be screwed into the matrix; If the core toughness is poor, a twist will break, can not be used. So "inside soft outside steel" is self-tapping screw to meet the use of performance, very important requirements.
(4) The surface of the product needs surface protection treatment, generally electroplating treatment. Some product surface must be treated by phosphate (photostatting), such as wall panel self - tapping screws for photostatting.
(5) Production by cold heading process. It is recommended to use high-speed cold heading machine and high-speed wire rolling machine or high-speed planetary wire rolling machine. High speed is emphasized here to ensure product quality. Only the head of tapping screw produced by high-speed machine is well formed and the thread quality is high.
