Slurry pump in drilling mud

2012-11-02

DaChuan Co.,Ltd liquid slag slurry pump structure strong and durable. Such as the installation of used correctly, pump life will be very long, but should pay attention to the following several aspects of maintenance.

First : liquid slag slurry pump impeller adjustment and change

Liquid slag slurry pump pump impeller and pump body between the clearance should be held in 0.5 1 mm or so, but by adjusting the bearing pedestal and support between gasket to adjust clearance, make the pump efficient operation. When the impeller and pump body wear to pump the performance and efficiency of the serious decline that cannot satisfy the application requirements, should replace worn parts.

Second, the liquid slag slurry pump bearing lubrication

Bearing at assembly has joined the right amount of grease, in motion can be regularly through the bearing body on two choke add grease, grease injection quantity cannot too much, too much can cause bearing fever. Add grease cycle and injection with operating condition is different, the large change. In use should be gradually accumulate experience, and should pay attention to grease must be kept clean, do not allow into dirt. At the same time suggest using clean lubricating oil.

Third : impeller adjustment (installed)

Bearing at assembly has joined the right amount of grease, in motion can be regularly through the bearing body on two choke add grease, grease injection quantity cannot too much, too much can cause bearing fever. Add grease cycle and injection with operating condition is different, the large change. In use should be gradually accumulate experience, and should pay attention to grease must be kept clean, do not allow into dirt. At the same time suggest using clean lubricating oil.

Third : impeller adjustment (installed)

For liquid slag slurry pump impeller adjusting no specific provision, when impeller and casing wear so much, that is, the performance and efficiency of the pump is seriously changed, they need to replace any wear parts. Fourth: wear a replacement

Submerged slurry pump wear rate and pump working condition and pumping medium abradability relevant. So wear a life such as impeller and pump body, etc for pump and installation situation is different and otherness. When the pump running no longer meet the pump characteristic of performance requirements, must the wear parts to replace. If pump first used in particular condition, especially in bearing grinding a damaged, will have serious consequences, it is suggested that pump start, every certain time to check parts, and estimate their wear degree, in order to ensure the service life of parts.

Fifth: the standby pump

Standby pump long time idle fixed, it is suggested that once a week by hand turn their shaft 1/4 turn, with this method, all of the bearing body ball can in turn loading.
