“We’ve had acts of violence, actually perpetrated onto assaults onto all of the disciplines of first responders, EMS, fire department,” Chief Schaeffer said. “The volume and the nature of our jobs have changed so much we’re actually in reaction mode all the time.”
Schaeffer said it used to be rare, but now he’s getting calls weekly from EMS or firefighters saying they were hurt by someone they were trying to help.
“All of us have been in situations where there have been shots fired or a shooting, or a bomb that may or may not have been detonated,” he said.
The Spokane Police Department does provide support on active scenes, but that isn’t able to happen all the time.
“The fire department does go to situations where either weren’t accurately reported, or they’re just, they have to go based on the resource disparity and we don’t have enough people available,” said Corporal Nick Briggs with SPD.
In November, Schaeffer will bring a proposal to the Public Safety and Community Health Committee for approval to fund bulletproof vests for the department.
“This added level of protection could give us that leverage that we need just to make the job safer for the people we have on the street,” said Chief Schaeffer.
Right now, only the firefighters’ ‘Rescue Task Force’ has bulletproof vests. They’re the team that responds to the most dangerous calls, like active shooters. They responded to the Freeman High School shooting.
The dimensions of the elastomeric stator change when the rotor begins rotating, increasing the differential pressure inside the pump and adding heat to the elastomer, causing the elastomer to swell and narrowing the tolerances between the rotor and stator. Note that there can be cases where the elastomer shrinks instead of swelling.
“The tolerance between rotor and stator is dynamic. The elastomer is a living, breathing element,” Noonan said.
The list of life-extending tips keeps coming back to understanding how changes to operating conditions, downhole fluids, and reservoir pressures can affect the PCP pump.
Noonan offered a sneak peek at results from a field in the Middle East where PCP run lives were doubled over a 4-year period by simply understanding PCP fundamentals and applying operating and pump selection criteria. The paper, SPE 206909, will be presented at the SPE Middle East Artificial Lift Conference and Exhibition in late October.
The thinking required to improved PCP performance is often counterintuitive. For these pumps, loose is better than tight and not targeting 100% volumetric efficiency downhole is the better long-term bet.
In order to account for the swell that the elastomer will see due to reservoir fluids and temperature, the acceptance pump efficiency from the bench test should not be any higher than 80% at the differential pressure that will be needed from the pump. This is only for low-viscosity fluids. For high-viscosity fluids, the acceptance criteria could be as low as 0% efficiency.
To better understand why that is the case, Noonan strongly recommended a paper by Evan Noble and Lonnie Dunn based on testing at Weatherford. The results showed many instances where the differential pressure across the pump was concentrated towards the discharge, rather than evenly spread over its length (SPE 153944).
The study showed why PCP pump failures often occur at the upper portion of the pump. It included a chart showing the importance of fluid slippage to distribute the differential pressure across the pump. The slippage is highest at 100% lift capacity.
Noonan talked about a field in Canada where the PCPs were failing early at the upper portion of the pump, and since the reservoir pressure had increased due to a waterflood, the differential pressure needed from the pumps was less. This chart demonstrates what occurred in the pumps and that the differential pressure had concentrated much closer to the discharge leading to elastomer failure.
The differential pressure curves will vary depending on the pump design (rotor/stator interference fit), operating speed, presence of free gas, and fluid viscosity. While the specifications can allow an expert an educated performance prediction, bench testing is needed to catch manufacturing defects and collect data needed to predict the interference fit between the rotor and elastomer once in the wellbore.

The particular improved upon cost-effectiveness regarding transistors generated the particular advancement regarding electronic digital planes methods through the entire 60s and also 1970s, in the beginning inside the armed service battle planes in which it absolutely was useful for Nav/Attack methods.
For quite some time, the effective use of electronic devices to be able to airborne methods has been restricted to analogue gadgets and also methods together with sign ranges and also voltages typically getting connected in a few linear or perhaps predictive approach. This sort of method has been typically susceptible to temperature bathe, move as well as other non-linearities. The particular rules regarding electronic digital calculating was comprehended for many decades ahead of the strategies have been placed on planes. Dimensions has been the key buffer.
The initial planes being produced in the usa making use of electronic digital strategies has been the particular Us A-5 Vigilante, any US ALL Deep blue carrier-borne bomber which usually started to be in business inside the 60s. The initial planes being produced in britain, designed to utilize electronic digital strategies about virtually any important level has been the particular ill-fated TSR a couple of that has been baulked from the BRITISH Authorities inside 1965. The particular engineering used by the particular TSR a couple of has been generally in relation to solid-state transistors, next inside comparison beginnings. In britain, it absolutely was not necessarily before the advancement with the Anglo-French Jaguar as well as the Hawker Siddeley Nimrod inside the 60s in which gun methods begun to significantly convey electronic digital calculating, even though over a minimal level when compared to the 1980s.
Considering that the overdue 1970s/early 1980s, electronic digital engineering is now more and more found in the particular handle regarding planes methods along with only for vision connected methods. An integral motorist on this program continues to be the particular option of cost-effective electronic digital info busses for instance ARINC 429, Mil-Std-155311 and also ARINC 629. This kind of engineering, along with the particular option of low-cost microprocessors plus more superior computer software advancement equipment, provides generated the particular popular program regarding avionics engineering through the entire planes.
It has superior to the level in which which has no planes method : like the lavatory method : continues to be still left unblemished.
The particular advancement and also improving usage of avionics engineering regarding city software regarding powerplant handles and also airline flight handles continues to be considering that the 1950s. Powerplant analogue handles have been released simply by Super inside the 1950s which usually made up power throttle signalling applied to planes including the Bristol Britannia. Total
specialist electronic digital powerplant handle started to be widely used inside the 1980s. Electronic digital major airline flight handle using a physical back up continues to be applied to the particular Airbus A320 and also A330/A340 family members making use of side-stick controllers and also around the Boeing, employing a standard handle yoke. Planes including the Dornier 728 household as well as the A380 look like taking on airline flight handle without the physical back up, yet together with electrically signalled back up.
The effective use of electronic digital ways to some other planes methods : tools methods : started out afterwards. Nowadays, avionics engineering will be strongly stuck inside the handle regarding practically all planes methods high voltage diode. As a result a knowledge with the dynamics regarding avionics engineering is essential inside understanding how the particular handle regarding planes methods will be attained.
