Internal maintenance instructions of brake pump
1. Maintenance of brake pump: brake pump is the power source of brake hydraulic system, and its vol-
ume efficiency will influence the speed and efficiency of actuator directly. It is not recommended to
remove or install the brake pump by non-professionals as it is a precise hydraulic element, and the
broken pump shall be returned to the manufacturer and repaired by professionals; after repair, brake
pump shall perform the test of airtightness and volume efficiency in order to guarantee its perfor-
mance and normal application.
2. Installation requirements for brake pump:
(1) You shall understand fully about rotating direction of brake pump and its compliance with the require-
ments of the entire machine before installation of the brake pump.
(2) Inlet and outlet port of brake pump shall be kept clean without dirts, and its surface shall have no inju-
ries so as to guarantee the sealing effect of O-ring.
(3) Before assembling the brake pump, check whether the mounting hole depth of gearbox spline is
larger than the pump's shaft extension length or not, in order to prevent from culmination phenome-
non, pump burnt out. Installation of spline shaft and spline housing shall be free without stuck.
3. Precautions for maintenance of brake pump:
(1) Apply a moderate force during assembly and disassembly of brake pump, and rude operation is not
allowed; user shall not open the brake pump without manufacturer's consent, otherwise they cannot
guarantee their product performance.
(2) Pay attention to maintenance of brake pump during operation, replace the hydraulic oil and check all
bolts at connections for looseness according to the maintenance manual.
(3) Oil inlet and outlet of brake pump shall be installed firmly and sealing device shall be secured, other-
wise it may cause oil leakage or air suction and affect the pump's performance.
(4) It is not allowed to operate the brake pump under maximum pressure, maximum speed or over-
loaded circumstances, otherwise, it may influence the service life.
(5) Oil temperature is required to be kept lower than 80 °C/176°F, otherwise it may affect the viscosity of
hydraulic oil and also accelerate the oxidation of fluid.
