Abstract
The utility model discloses a safety valve part for a gear oil pump. The safety valve part comprises a valve body, wherein a vertical passage is arranged on one side edge of the pump body; an overflow valve core is mounted in the vertical passage; a pressure adjusting spring is mounted at the upper end of the overflow valve core; a spring seat is mounted at the upper end of the pressure adjusting spring; a pressure adjusting screw is mounted at the upper end of the spring seat; a nut is sleeved outside the part of the pressure adjusting screw, which extends out of the vertical passage; a plug is mounted at the lower end of the vertical passage; a filter screen is mounted at the lower end of the plug; an elastic collar is mounted at the lower end of the filter screen; and a connecting part is arranged at the lower end of the elastic collar. The safety valve part is simple in structure, the service life of the gear pump is prolonged, noises are reduced and the maintenance is benefited.
Description
Technical field:
The utility model relates to the oil pump field, relates in particular to a kind of safety valve component of gear oil pump.
Background technique:
Gear oil pump is widely used in the industries such as oil, chemical industry, boats and ships, electric power, grain and oil, food, medical treatment, building materials, metallurgy and national defence scientific research, and gear pump is to nibble mutually with two gears to rotate work, and is less demanding to medium.General pressure gear oil pump power is below 6MPa, and flow is larger.Gear oil pump is equipped with a pair of swiveling gear in the pump housing, an active, and one is passive, relies on the intermeshing of two gears, divides two independently parts the whole active chamber in the pump.A is suction chamber, and B is discharge side.Gear oil pump in the running driving gear drives the driven gear rotation, and (A) just forms parital vacuum in the suction side when gear is thrown off from being engaged to, and liquid is inhaled into.The liquid that is inhaled into is full of each tooth paddy of gear and takes to and discharge side (B), and liquid was extruded when gear entered engagement, forms highly pressurised liquid and outside the pump discharge excavationg pump.Therefore imagination provides a kind of equipment to solve this problem.
The model utility content:
The purpose of this utility model just provides a kind of safety valve component of gear oil pump, solves the job insecurity of existing gear pump, the problem of serious wear.
The technical solution adopted in the utility model is:
A kind of safety valve component of gear oil pump, comprise the pump housing, pump housing side is provided with Vertical Channel, relief valve spool is installed in the Vertical Channel, the relief valve spool upper end is equipped with pressure adjusting spring, the pressure adjusting spring upper end is equipped with spring seat, and the spring seat upper end is equipped with pressure regulating screw, and the part that pressure regulating screw stretches out Vertical Channel is set with nut outward; The Vertical Channel lower end is equipped with plug, and the plug lower end is equipped with filter screen, and the filter screen lower end is equipped with circlip, and the circlip lower end is provided with joint, and the joint lower end is equipped with emergency valve seat, between emergency valve seat and the joint rubber sheet gasket is installed; The joint side has side outlet, and side outlet is equipped with screw plug outward, is provided with the side sealing circle between screw plug and the pump housing.
Described pressure regulating screw is set with seal ring outward, is provided with the side sealing circle between screw plug and the pump housing.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by being provided with Vertical Channel at pump housing side, relief valve spool is installed in the Vertical Channel, the relief valve spool upper end is equipped with pressure adjusting spring, pressure adjusting spring upper end is equipped with spring seat, and the spring seat upper end is equipped with pressure regulating screw, and the part that pressure regulating screw stretches out Vertical Channel is set with the structure of nut outward, make it simple in structure, improve the life-span of gear pump, reduce noise, convenient for maintaining.
