Instructions for use
The working medium of the series pump is YB-N32 hydraulic oil, the ambient temperature is lower than 10`C, can switch to YB-N22 number of hydraulic oil, environmental temperature is higher than 40`C, you can switch to YB-N46 hydraulic oil.
The liquid level of the oil tank in the work should always be kept on the center line of the oil mark, so that the oil pump suction. When refueling, the application of 120 mesh filter to filter out impurities in the new oil. Frequently used, every two months to clean an oil filter, six months to clean the oil tank, while the replacement of new oil.
The normal operating temperature of the oil pump is 10`C-50`C. Oil temperature is too high, need to take measures to cool or stop the pump, oil temperature is too low, adopt heating measure or low-pressure operation to improve the oil temperature.
Before starting the motor, the valve should be changed to the middle. Point move several times, in case of high pressure pump suction air, the air out of the rear can be used.
The pump working pressure set at the factory shall not increase.
High pressure hose factory, after 1.25 times the rated pressure of the pressure test. Due to the aging of the resin, the user should pay attention to regular inspection, six months to check once. When checking to do pressure test, the leakage, bump or blasting case must be replaced. When in use, should avoid discounts and appear sharp, but not too close to the anti blast hose, thrown from the hurt. Fixed occasion, can be replaced by steel tubes.
The series pump once a year. All the parts with kerosene cleaning, pay attention to the protection of the mating surface shall not be any knock against, assembly, all moving parts should be flexible movement and no local blocking. Five, common failures and troubleshooting methods
fault
Main cause
Elimination method
Insufficient pressure
1 safety valve adjustment value is too low.
2 safety valve cone valve stuck or wear.
3 joints loose or seal caused by leakage.
4 pressure gauge failure caused by pressure response distortion.
1 adjust the safety valve.
2 check the cone valve or valve replacement or repair
3 fastening joint or replace seal
4 check the pressure gauge maintenance pressure gauge block
fault
Main cause
Elimination method
High pressure discharge
1 plunger coupling with clearance wear too large
2 plunger or spring break
3 all the leakage caused by inadequate flow
4 temperature caused by the low oil difficult, high temperature caused by the volume efficiency
5 Hydraulic too low, oil pump suction
6 high pressure pump suction or no high pressure oil discharge (suitable for pumping station with low pressure pump)
1 generally replace the plunger even parts
2 replace the parts
3 fastening joint replacement seal
4 temperature control in 10` C-50`C
5 refueling
6 for the first time before the use or replacement of oil, so that the motor back to the minute or move several times.
