Steps for installation of hot oil pump
Installation of hot oil pump
Installation of hot oil pump
1. Preparations before installation
1) Preparation of technical data
(1) Technical documents of design and pump should be prepared before construction, and construction plan of RY hot oil pump should be prepared at the same time;
(2) Learn to understand drawings, construction plans and other technical data before construction.
2) Foundation acceptance
The function of the base is mainly to fix the machine equipment in a certain position to make it bear all the gravity of the machine and the dynamic load produced by the machine in operation, and absorb and isolate the vibration produced by the machine, to prevent the occurrence of resonance phenomenon.
Before the installation of the hot oil pump, the competent department shall organize the relevant personnel of the civil construction unit and the equipment installation unit to conduct a comprehensive inspection on the construction quality of the foundation.
It mainly includes the following contents:
(1) The appearance of the foundation shall be inspected, and there shall be no cracks, honeycomb, cavities, exposed tendons and other defects.
Defects should be dealt with if found.
(2) Retest and check the geometric dimension and position of the foundation according to the civil engineering foundation drawing and technical documents of the pump.
If there is no special requirement, the acceptance can be carried out according to GB 50231-98(General Code for Construction and Acceptance of Mechanical Equipment Installation Engineering). The allowable deviation is shown in Table 6-2.
The alignment of the pump is measured with a line hammer according to the center line marked by the foundation, so that the vertical and horizontal center lines of the hot oil pump are consistent with the center line of the foundation.
Make sure there is no difficulty in installing piping or connecting to other equipment.
The longitudinal centerline of the pump is based on the centerline of the pump shaft.
In the longitudinal centerline alignment, can use the method of hanging hammer line side measurement.
The vertical line is hung from the center of the pump shaft so that it coincides with the center line on the base.
The center line of the inlet and outlet pipe flange is often used as the positioning datum and is aligned with the method of pulling wires.
Take the point or line demarcated on the workshop wall or foundation as the installation datum, pull a straight line, and the center line through the inlet and outlet pipeline flange coincides.
Can also be installed and adjusted the center line of the machine pump has been used as the measurement datum to calibrate, so that the transverse center position of the pump body to meet the technical requirements.
Ensure that there is no big deviation when the pump body is connected with the pipeline or other machinery and equipment.
The development direction of hot oil pump is small pulsation
In order to improve the performance of hot oil pump and reduce the manufacturing cost, it is required to meet the design requirements of smaller volume, faster response, smaller pulsation and lower noise of hot oil pump.
High pressure multistage diesel pump classification
Open or half open in high pressure multistage diesel pump is generally adopts the volute pump body, pump casing in main shaft centerline plane separately, the pump according to the main shaft is installed in the open in different points level and vertical open type two kinds, it is each impeller has a corresponding volute suction chamber and pressure out of the room, which is equivalent to a few single stage volute pump assembly work on the same shaft series.
What are the common reasons for the failure of the oil pump
Generally speaking, the mechanical oil transfer pump is very reliable. Even if it fails, it is often the diaphragm rupture that causes insufficient oil transfer. Sometimes the rocker arm or spring of the oil pump is worn out excessively, which will also cause insufficient oil delivery. The fault is easier to identify. The old-fashioned oil pump can be repaired, but the new-style oil pump cannot be disassembled, so it should be replaced once it fails.
Analysis of the types of oil transfer pumps
Scope of application of KCB oil transfer pump: It is suitable for conveying lubricating oil or other liquids with similar properties to lubricating oil that do not contain solid particles and fibers, are non-corrosive, have a temperature not higher than 150 °C, and have a viscosity of 5 to 1500 cst.
Hot oil pump bearing lubrication
the bearing oil level is too low, so that some parts of the RY hot oil pump bearing can not be lubricated, so the bearing will produce wear and heat, so that the bearing is burnt out.
Common faults and countermeasures of electric grease gun
The electric grease gun is a miniature electric grease gun, which consists of a casing, a frame, a plunger pump mechanism, a crank-slider mechanism, a gear reduction mechanism, an oil supply system, an operating system and a power system: its structure is small and the battery is built-in, An external charger can be installed, driven by a DC motor, the price is moderate, labor-saving, fast, easy to operate, high pressure, and can meet the general mechanical oiling requirements.
Precautions and maintenance when using electric grease gun daily
Before use, check whether the valve spring, steel ball and other parts are in short supply, the sealing condition of the piston and the oil gun head, and pay attention to check the squeezing effect to ensure the smooth progress of the maintenance work.
