b. After installed the pump cover, check the pump cover and the clearance between the impeller ( To see from the exit) , should guarantee the clearance at about 2 mm, high temperature medium pump, the clearance in 2. About 5 mm

c. Clearance between the impeller and the pump body can not meet the requirements, can increase or decrease thermal gasket between the impeller and shaft sleeve and adjusting collar adjusting nut to adjust

d. cover and the clearance between the impeller can not meet the requirements, can increase or decrease between pump body and pump cover gasket to adjust the

e. Hand plate dynamic coupling, until the move, according to the launch step again drive

mine with wear-resisting centrifugal pump pump and seal the runtime maintenance:

a. Often see outside cooling system work is normal, should check the cooling water supply is normal qso cooling water pump, supplying of cooling oil pump stay in, check the oil level when filling in time

b. The operation of the pump when close the outlet valve is called the running state of the closed pressure, all plastic or lining plastic pump pressure closed running time should be shortened as much as possible, the normal temperature medium is limited to not more than 10 minutes, high temperature medium had better not more than five minutes

c. Keep the machine without water, prevent motor be affected with damp be affected with damp
