Basic oil pump inspection, maintenance and heavy attention _

the common fault is the oil pump, oil cannot reach the limit vacuum, and oil is blocked and cannot be started. Therefore, maintenance is very important. General maintenance inspection is the color of oil pump, check the oil level, check the entry and exit filter, etc. The following small series will share the pump inspection, repair and refilled prevention measures.

always check the position of the vacuum pump oil level. If do not conform to the requirements, it must be adjusted to meet the requirements. Use the vacuum pump is running, the center of the oil level in oil standard.

always check the oil quality, and find new oil should be replaced in a timely manner to ensure normal work of the vacuum pump.

users according to actual conditions of use and whether to meet the performance requirements to consider oil change period.

usually, when using the new vacuum pump to remove clean and dry gas, suggest you to change the oil every 100 hours. In oil can't see the black metal powder, can extend the oil change period in the future.

under normal circumstances, should be in operation after 2000 hours of vacuum pump overhaul:

check the service life of rubber seal,

check if the exhaust valve failure.

remove deposits on the valve plate and the exhaust valve seat of dirt.

clean parts of the whole vacuum pump chamber, such as rotor, vane, spring, etc.

usually use gasoline cleaning and drying. Rubber parts after cleaning, dry with dry cloth. Should be careful when cleaning and assembly. Oil pipe blocked, pipes must be cleaned to ensure that the pipeline flow.

to replace aging seals, add and replace the oil, clean the oil pipe line, replace the aging distributor, rotor and spring, and replace the damaged power components and motor coil.

after reassembling, should be tested. Normally, it must run 2 hours, and two times an oil change. Due to the vacuum pump in the process of cleaning will have a certain number of, so in the normal after the operation will be able to enter the normal operation.

vacuum pump parts have clean, repair and reinstall:

a, before installation, please check the devices of fasteners is loose, and the place if there is any foreign body congestion, the runner to avoid the damage of rotary vane water pump runtime and pump body.

2, should not be increasing the weight of pipe on the pump, pump so as not to cause deformation. During the installation process must tighten the anchor bolts, to avoid excessive vibration and impact in the start-up process of the pump performance. For the convenience of maintenance and the use of safe, please into the pump, the installation of a control valve on the outlet pipe, and install a pressure gauge near water pump exports, to ensure that the rated head and flow rate within the scope of operation, and prolong the service life of pump.

three, after the installation of pump shaft, rotary vane should be no friction or blocked.
