Oil pressure system oil temperature rise fast and high reasons

Oil pressure system oil temperature rise fast and high reasons are:

① The internal parts of the blade pump of the hydraulic press are strained and heated, and the leakage between the valve plate of the blade pump and the end face of the rotor is large due to strain or wear, and the pump volume efficiency is low and heated;

② The control box spool and box hole due to wear internal leakage, pressure loss and heating temperature rise;

③ The pressure regulation of the back pressure valve is too high, exceeding 0.8MPa;

④ Ball valve A pressure adjustment is too high, more than 0.8MPa;

(5) The pressure regulating spring of the relief valve is installed incorrectly, and the elasticity is too large;

The bed doubles as a fuel tank, the tank capacity is not enough when designed, and the amount of oil added to the tank is not enough, it is easier to heat up.

Oil press temperature exclusion methods are:

① Check and repair or replace strained and worn parts, repair vane pumps and control boxes;

② The pressure of the back pressure valve is adjusted to 0.6~0.8MPa;

③ Repair and adjust the pressure of ball valve A to 0.6~0.8MPa;

Replace the appropriate relief valve spring, and correctly adjust the pressure to the specified value;

⑤ Add enough oil pressure to the oil mark position of the tank.
