KCB gear pump

KCB series gear pump USES: KCB series gear pump is suitable for the transportation temperature is not higher than 150 ℃, the viscosity is not more than 1500 CST various have similar liquid lubricity and properties.The pump gear is all made of hard tooth surface and equipped with safety valve to protect the motor from overload.

I. principle and characteristics of surface sticking of gear pump

In recent years, the surface adhesion technology has been widely used in the maintenance of equipment in China, which is applicable to the repair of various materials of parts and equipment.Its working principle is to add molybdenum disulfide, metal powder, ceramic powder, and fiber and other special packing adhesive, surface coated directly on the material or parts, wear-resisting, corrosion resistance and other functions, mainly used for surface strengthening and repairing.Its process is simple, convenient and flexible, safe and reliable, does not need special equipment, just put the surface with good adhesive coating still good parts, finishing can stay after curing, often operating at room temperature, won't make parts joule equivalent effect and deformation, etc.

2. Adhesive coating process

When the uniform wear amount of small area in the outer circle of the axle sleeve, the end face of the axle sleeve, the end face of the gear wheel or the inner hole of the pump shell is between 0.15mm and 0.50mm, and the scratch depth is more than 0.2mm, it is advisable to adopt the adhesive coating repair technology.Coating process of adhesive coating: initial cleaning, preprocessing, cleaning and activation treatment, preparation of repair agent, coating, curing, dressing, cleaning or post-processing.

Although the adhesive coating technology is relatively simple, but the actual construction requirements are quite strict, only by the choice of good adhesive, may not be able to obtain high adhesive strength.Should choose the appropriate adhesive, and strictly in accordance with the correct method to stick with appropriate adhesive, and strictly in accordance with the correct process principle line mucous coating can get satisfactory effect.

The rotation direction of gear pump should be consistent with the inlet and outlet.Gear pump if a run, or long - term idle after use, in the case of no - load or small load running around an hour.If abnormal temperature rise, leakage, vibration and noise are detected in advance during the running-in phase, it shall be stopped for inspection.Check valves and safety valves are fitted with a check valve on the output pipe of the gear pump.

The gear pump is enclosed in a shunt valve and provides ink evenly to the gear pump through a single pipe supply system.Synchronous ac motor is used in the pump and its drive system.Rotary valves are used to determine the amount of ink, and these valves are in the same position as the inkjet keys they replace.The valve operates in two dimensions.
